HAN D AND FOOT CONTROLLED GAS SYSTEM Technical Field of the I nvention

This invention relates to a gas system which enables gas system used in tractors be controlled by hand and foot. State of the Art (Prior Art)

The fuel flow to the engines of vehicles is generally controlled by a pedal which is actuated by foot. The fuel flow to the engine increases or decreases proportional to the amount of actuation applied by the user on the pedal I n addition to vehicles, the tractors have a handle which is actuated by hand in order to control the fuel flow to the engine. Spirals which are provided in the continuum of foot and pedal adjust the gas flow and control fuel flow to the engine. Handle and pedal spirals are connected to the pump separately on the engine and enable the controlling of engine speed. The condition that the spirals are independent from each other may lead to differences in speed in hand and foot gas courses. Hand gas which is adjusted with the help of handle is important during the processing of the field with tractor. I t is required to process the field at a fixed speed together with the equipment attached to the tractor. I n addition to the difference of speed, the spiral that extends from the handle may break after deformation over time. I n the patent application No. CA 1 169743A1 , a gas system which could be controlled by handle and pedal is explained. By means of a protective sheath which is provided on the spiral in the gas system , it is aimed to avoid the deformation. Another purpose of the invention is to ensure that spirals are used individually or collectively. The disadvantage of the application in question is that the spirals affect the operation of one another. When the user transmits actuation to the handle or pedal, other elements are affected from this movement. Thus, differences in speed occur in adjustments between elements.

I n the utility model application with publication No. CN203547930U, a gas system is disclosed wherein both gas pedal and handle controls are connected to the same spiral. The spiral to which the pedal is connected is extended and its end is connected to a transmission mechanism. The transmission mechanism is connected to the spiral that is received from the handle. When an actuation is transmitted from the handle, the mechanism takes the movement and transmits it to the other gas spiral. By this means, the gas system is aimed to be controlled from a single spiral by means of transmission elements. This system has a structure which could decrease deformation that could occur on the spirals. However, the adjustment of motor speed and prevention of speed losses will not be taken under control.

D Rotating Point Detailed Description Of The I nvention

I n this detailed explanation, the innovation which is the subject of the invention is explained with examples which are for the purposes of better understanding of the subject and which shall not constitute any restrictive effect. Accordingly, elements which comprise a tractor gas system (10) and a tractor gas system (10) itself are explained. Referring to Figure 1 , an exploded view of the elements constituting the tractor gas system (10) is given. The tractor gas system (10) mainly comprises the following; a handle assembly (20) ; a pedal assembly (30) ; a transmission mechanism (40) which enables integration of the handle assembly (20) with the pedal assembly (30) , and a gas spiral (50) which reaches to the gas piston of the tractor that is in contact with the transmission mechanism (40) .

The tractor gas system (10) preferably has a handle assembly (20) which is located in the tractor cabin in such a way that it can be reached by the tractor user. The handle assembly (20) is contacted to the tractor frame by the help of a carrier body (21 ) . A pin (21 1 ) is provided on the body (21 ) . A handle (22) is contacted with the carrier body on the pin (21 1 ) . The handle (22) is contacted on the pin (21 1 ) from around the middle region. The handle (22) could make an angular rotational movement on the point where the pin (21 1 ) is defined. The carrier body (21 ) also determines the movement limits of the handle (22) . The user could perform forward - reverse, angular movement with the handle (22) within the limits mentioned. There is a connection extension (221 ) provided on the handle (22) and defined after the pin (21 1 ) . The contact extension (221 ) defines a movable end. The connection extension (21 1 ) moves in the same manner with the angular movement of the handle (22) . There is a pin (222) provided on the connection extension (221 ) in a sufficiently vertical manner. There exists a handle spiral (23) which enables contact of the handle assembly (20) with the transmission mechanism (40) . The handle spiral (23) has a mechanism connection end (232) and a handle connection end (231 ) provided thereon. The handle connection end (231 ) contacts with the pin (222) and the mechanism connection end (232) contracts with the transmission mechanism (40) .

The tractor gas system (10) has a pedal assembly (30) which is provided so as to be controlled by the user by foot inside the tractor cabin. The pedal assembly (30) is contacted with the tractor frame over a carrier body (41 ) . There is a connection socket (31 1 ) on the pedal (31 ) which enables contact with the carrier body (41 ) . The pedal (31 ) could perform an angular rotational movement on the point to which the connection socket (31 1 ) is connected. The pedal (31 ) has a pressing end (32) provided by the user. The user applies a force to the pressing end (32) enabling the pedal (31 ) to perform the rotational movement in question. There is a mechanism end (33) which is located at the continuum of the connection socket (31 1 ) over the pedal (31 ) . The pedal assembly (30) gets into contact with the transmission mechanism (40) through mechanism end (33) . A spring socket (332) provided on the mechanism end (33) as well as a pin (331 ) extends sufficiently vertical to the mechanism end (33) . There is a spring (34) one end of which is located in the spring socket (332) in question and the other end to the tractor frame. When the force which is applied on the pedal assembly (30) is removed, the spring (34) enables that the pedal assembly (30) returns back to the former position.

The tractor gas system (10) has a transmission mechanism (40) which enables contacting the handle assembly (20) and pedal assembly (30) to the gas spiral (50) by integrating one another. The transmission mechanism has a carrier body (41 ) on which the elements a are located on the transmission mechanism (40) . The carrier body (41 ) has a L shaped profile. The carrier body (41 ) is contacted to the tractor frame over a section of the form which it has. The vertical part defines the contract part for pedal (31 ) and transmission group (40) elements. The carrier body (41 ) has a pedal extension (41 1 ) and a group extension (412) which extends on the opposite direction to the pedal extension (41 1 ) The pedal (31 ) is connected with the pedal extension (41 1 ) on the connection socket (31 1 ) . The transmission mechanism (40) has a gas link (42) contacted with the group extension (412) . There is a spiral pin (421 ) and a groove (422) provided on the gas link (42) . The groove (422) has a structure which is suitable with the form of the pin (331 ) and complements the curved structure of the pin (331 ) in figurative way. There is an puller link (43) which is located in the neighborhood of the gas link (42) and contacted to the gas extension (412) . On the puller link (43) an align (431 ) is provided which extends towards the gas link (42) so as to be closed to the end part. The align (431 ) grasps the gas link (42) so as to abut the groove (422) . On the other end of the puller link (43) there is provided a chamber housing (432) . The handle spiral (23) contacts the chamber housing (432) over a connection chamber (44) in which the mechanism connection end (232) is located. A nut (45) which contracts the mechanism connection end (232) enables the mechanism connection end (232) to protect its position in the chamber (44) . I n this manner, the handle spiral (23) contacts with the transmission mechanism (40) over the puller link (43) . A number of washers (46) are provided between the carrier body (41 ) , has link (42) and puller link (43) . The washers (46) enable that there is a certain distance between the elements and the frictions arising from the movement are decreased. The washers (46) also assist in the elements in question to be placed on the group extension (412) . A stopper (47) is located at the end of the group extension (412) so as to remain outside the elements. The stopper (47) enables the elements in question to keep their position on the group extension (412) . Gas link (42) and puller link (43) could perform rotational movement on group extension (412) .

The transmission mechanism (40) is in contact with the has spiral. The gas spiral (50) has two ends, being one mechanism end (51 ) and one gas piston end (52) . The gas spiral (50) is in contact with the transmission mechanism (40) by means of the contact of spiral pin (421 ) of mechanism end (51 ) . The movement that comes from transmission mechanism (40) is transmitted to the end of gas piston (52) . Gas piston end (52) is in contact with the gas piston (not shown in the figure) over a spring (not shown in the figure) . The movement that comes from mechanism end (51 ) is directly transmitted to the end of gas piston (52) . The power that comes from mechanism end (51 ) moves the gas piston end (52) if it is higher than the traction power of the spring. When the force received from the mechanism end (51 ) is revealed, it returns the gas piston end (52) to previous position. Referring to Figure 2, the profile view of the mounted status of transmission mechanism (40) is given. I n the condition in question, the handle assembly (20) and the pedal assembly (30) are at the beginning condition. For that reason, the transmission mechanism (40) is at stable status at the beginning condition. Elements which comprise the pedal assembly (30) and the transmission mechanism (40) are located at opposite sides of the carrier body. The pin (331 ) that is located on the mechanism end (33) is located inside the groove (422) . By means of the contact of puller link (43) to the gas link (42) over the pin (331 ) of the pedal over the align (431 ) , two different actuation sources are made in contact with the gas spiral (50) from a single point. The group extension (412) defines a rotating point (D) for the transmission mechanism (40) . Similarly, the pedal extension (41 1 ) defines a rotational point for the pedal assembly (30) . Both rotational points, namely the pedal extension (41 1 ) and group extension (412) are not concentric. For that reason, in order to reach to the gas link (42) , the mechanism end (33) and puller link (43) do not rotate at equal amounts. The design details at mechanism end (33) and puller link (43) actuate the gas link (42) from two neighboring points, thus abolishing the differences in question. By this means, it is ensured that the dimensions of the transmission mechanism (40) are minimized and made suitable for the pedal assembly (30) and cover less space inside the cabin.

Referring to Figure 3, a perspective view is given of the condition where force is applied to a pedal assembly (30) . When force is applied to user pressing end (32) , the pedal (31 ) starts to rotate on the rotational axis defined by the pedal extension (41 1 ) . Since the force applied by the user is more than the strain force of the spring (34) the mechanism end (33) starts to rotate. Since the pin (331 ) which is located at the mechanism end (33) rests on the groove (422) , the movement that comes from the pressing end (32) is transmitted to the gas link (42) . The gas link (42) performs rotational movement on the rotation point (D) defined by the group extension (412) . The spiral pin (421 ) tracts the mechanism end (51 ) towards the rotational direction and enables transmission of the movement to the end of gas piston (52) . As the user removes the force applied to the pressing end (32) , the force applied by the spring (34) overcomes the force received at the mechanism end (33) and the pedal (31 ) returns to the initial position.

Referring to Figure 4, a perspective view is given of the condition where force is applied to a handle assembly (20) . I n case that the user applies a force on the handle (22) , the connection extension (221 ) moves in the rotational direction defined by the pin (21 1 ) . The pin (222) transfers the movement to handle connection end (231 ) and enables the mechanism connection end (232) to be drawn. The movement that is received at mechanism connection end (232) is transmitted to the puller link (43) . The puller link (43) starts to rotate at rotating point (D) axis. The support extension (431 ) starts to move the gas link (42) on the axis of rotation point. The movement that is received at the gas link (42) is transmitted to the gas spiral. As the user brings the handle assembly (20) to the initial position, the transmission mechanism (40) starts to move in the opposite direction. The transmission mechanism (40) returns to the beginning condition. Similarly, since the force received at the mechanism end (51 ) is removed, the spring located on the gas piston returns the gas spiral (50) back to its beginning position. Referring to Figure 5, a profile view is given of the condition where force is applied to a handle assembly (20) . When a force is applied to the handle assembly (20) or pedal assembly (30) , it moves on the transmission mechanism (40) and the gas link (42) draws the gas spiral (50) . A gap (A) occurs between the gas link (42) and the actuating element according to the resource where the user applies force. I f the user wants to transmit actuation from the handle assembly (20) to the transmission mechanism ; the puller link (43) moves the gas link (42) . Meanwhile, a gap (A) occurs between the gas link (42) and the mechanism end (33) . I f the user wants to transmit actuation from the pedal assembly (30) to the transmission mechanism ; the mechanism end (33) moves the gas link (42) . Meanwhile, a gap (A) occurs between the gas link (42) and the puller link (43) . This condition provides the user with the advantage of continuity during the gas setting. I n case that the user shifts from one assembly to another for making gas adjustment, the user could continue to make adjustment without any loss of course. For example, when the user brings the handle assembly (20) and gas adjustment to a certain point and wants to continue gas adjustment with pedal assembly (30) , first the user starts to apply force on the pedal (31 ) . Since there is a gap (A) between the mechanism end (33) and gas link (42) , the movement that comes from the pedal (31 ) does not directly affect the gas link (42) . I t is required that the mechanism end (33) should first close the gap (A) and contact the gas link (42) . After the mechanism end (33) contacts the gas link (42) is moved and a movement that comes from the pedal (31 ) to the gas spiral is started to be transferred. A similar situation also takes place when the user wants to continue with the gas adjustment after bringing the pedal assembly (30) and gas adjustment to a certain point. The user firs starts to apply force on the handle (22) . The handle (22) takes the movement and transmits to the handle spiral (23) and from there to the puller link (43) . The puller link (43) for closes the gap (A) that is between the gas link (42) . The puller link (43) contacts the gas link (42) and transmits the movement that is received from the handle (22) to the gas link (42) .

For both conditions, the puller link (42) is located at a certain position. For that reason, a certain course is provided to the gas spiral (50) . When the users want to continue with the gas adjustment with the second assembly, the actuation applied by the users to the gas link (42) is transferred starting from the current position. During the movement transferred to the gas link (42) , since there is no difference between movement transmission points, no course difference occurs on the gas spiral (50) . For that reason, there is no change in the gas amount transferred to the engine. By this means, there is no sudden speed loss or speed increase on the engine. Since the handle assembly (20) is not affected when force is applied to the pedal assembly (30) , the handle spiral (23) is subject to continuous actuation. By this means, the life of handle spiral (23) is extended.
