HOLDER TO PREVENT SLIPPAGE BETWEEN LEAF SPRINGS
Document Type and Number:
WIPO Patent Application WO/2011/155908
Kind Code:
A1
Abstract:
This invention is a piece which prevents the springs, which connect the frame and the barrel, from sliding over each other during the pullings and pushings between the frame and the barrel in vehicles. The piece which is installed between the top level spring and the spring plate by being squeezed with the stud and the clamps, prevents the barrel from moving by being inserted in the barrel sockets of the feet which hang down from the right and left sides of the springs. The transmission of power between the frame and the barrel is provided via this piece. As a result, the connection distances of the wheels of the vehicle are preserved continuously without losing their balance, in the right and parallel proportion.

DESCRIPTION

HOLDER TO PREVENT SLIPPAGE BETWEEN LEAF SPRINGS

The current invention is a piece which eliminates the balance ruining problem in the directly proportional and parallel truck wheels even in hard conditions.

Trucks which occupy the greatest position in road transport have almost the same features with a luxury car. It is a fact that loaded trucks which have advanced features in terms of traction, power, speed, comfort and transport capacity can exceed the maximum legal speed limit while they go up and down a ramp. In such advanced trucks as the weight and speed increases, a greater force is administered on balancing parts.

All engine transmission differential movements are practiced by traction wheels and they bear many times more power than that administered on the shaft and balancing parts of the front wheels. During braking a certain force is administered on the shaft and balancing parts of the front wheels. Balance system installed by pressing the available springs arranged one on top of the other with 1 stud and 2 clamps can be long lasting.

Total weight of trucks concentrates on the frame. Frame is led by traction wheels. Traction wheels push the frame via the barrel to commence the movement. When accelerator is stepped they push more and increase the speed. Engine brake decreases the speed by pulling backwards when the retarder is used. Hence, all movements of trucks occur when the frame pulled or pushed by the barrel. These pullings and pushings begin with the movement of the vehicle and end until it stops. When the accelerator is stepped, engine brake, foot brake and retarder is used intensiveness increases as the orders in the reverse direction of flow of the frame come to the barrel via traction wheels. In semi-firm, loose and marshy grounds, when the vehicle is mired these pullings and pushings are strong. Springs slide over each other to front and back. Stud becomes bent, balance is ruined. The shape of the wheels is as shown in FIG. 2.

As shown in FIG. 3, barrel and frame is connected in the following method: springs arranged one on top of the other by taking their length into account are placed on the barrel. Frame connection is performed with the front tips of two of the main floor springs on top. Rear tips are released in a way that they can swing back, forth, up and down within the scale. Through the middle holes of those springs a stud is passed and squeezed. With 2 clamps, springs are connected to the barrel by squeezing them downwards as in FIG. 3. A spring plate is placed upon the springs and a chock is placed between the spring and the barrel. Some truck brands arrange the height by increasing the number of short springs instead of using chocks. Even when you look at FIG. 3 with the naked eye, it is noticed that the balance can not be preserved during the back and forth movement of the barrel with the squeezing of 2 clamps and 1 stud, that there is not a piece which will prevent the springs from sliding over each other and take the position in FIG. 4 and that a strong piece is required in that area to support the force. Even if we assume that the vehicle is not subjected to any challenges and operates with a light load on highways, it is a fact that the clamps will stretch in time and lose their squeezing effect by expansion, that the stud will bend down during a normal cruise; because, the pushing between the two ends of the stud is so interesting that the top end of the stud is connected to the top spring and the top spring is connected to the frame. The lower end of the stud is connected to the barrel with the lowest spring. The other springs are in the middle... If we only take the first movement of the vehicle into account, when the barrel gives the first movement to the 25 tons of standing frame, the frame will want to stay in its place from the lowest spring, namely the lower end of the stud; naturally the frame will pull back. The frame equals the top spring, namely the top end of the stud... Think of this start in ramps or marshes, where the 25 tons become 75 tons etc... It will not be possible to hold the springs together with squeezing, the springs will slide over each other and the stud will bend. This problem which can be eliminated in vehicle maintenance services in 3 hours and loss of Money will now be eliminated in a short period of time.

When the stud becomes bent, the wheels take the form in FIG. 2 and the following problems occur:

1- Fuel consumption increases.

2- Tires wear out.

3- Traction wheels swerve

4- Road holding decreases as a result of the tires becoming cross as to each other. 5- The vehicle moves with the humming of wheel.

6- Sliding occurs in rainy weathers.

7- Drifting occurs while turning (More to one side...)

8- The steering wheel deviates.

9- The front wheels are required turned to one side constantly in order to go straight.

10- The vehicle slaloms.

11- The vehicle will swerve on the road

12- The inside of the wheel wears out.

13- Since the worn out wheels of the vehicle are generally the tracking wheels, they force the vehicle like it is going to throw it off the road. They apply a force outwards from the waist of the frame. Since even this condition of the really-heavy vehicle is a problem itself, it is a fact that it will spawn lots of small and large problems.

INTRODUCTION OF THE DEVELOPED PIECE;

The piece which can be seen in Figures 5 - 6 - 7 - 8 - 9 - 10 is attached to the front, axle, tracker and all springs which are piled on top of each other. When it is attached, it provides extra force without constraining any movement of the vehicle. The piece is attached in a way that the feet will go down towards the barrel over the top spring, as shown in FIG 5. The stud is passed over the hole in the center of the piece and it is squeezed together with the springs. When it is being placed on the barrel with the springs, the ends of the feet of the piece are placed in the sockets which are added to the barrel or which have been there originally. The sockets can be placed on the sides of the chocks between the barrel and the springs as well as being placed at the location which is the most appropriate one in the vehicle. The function of the socket is to fix the feet of the piece on the barrel. The socket is a rectangular box. There are openings at the bottom of the box for the outflow of the accumulation of dirt on the sides. There are panels which are used for preventing the feet from moving back and forth. A balance adjustment is performed on the panels as well. There is a small space for movement at the sides and the bottoms of the socket. The socket should be installed appropriately in order for the barrel to not be torn in problems such as the wheels being damaged from the outside, traffic accidents etc. The barrel should be removed or should come off from the socket without any damage.

Its function is as follows: the piece, which is installed by being squeezed between the top level main spring contacting with the frame and the plate by the stud and the clamps, prevents the barrel from sliding back and forth. The piece which is installed by centering the top level main spring center stud hole, couples with the main level as if integrated. The feet of the piece move down towards the center of the barrel and couples with the socket of the barrel. Among the serious pullings and pushings occurring between the barrel and the frame, the barrel always keeps its place and balance, and its distance to the frame. The problems of the stud sliding, reclining back or forth and bending are removed. The wheels always preserve their right and parallel proportion.

The same work can be completed by changing the shapes of the same piece and socket in question and places where they are installed as a modification of shapes and locations.

Building the back of the piece in integration with the plate or making a fixation where the back part is not apparent and the feet move down the plate to form the socket. When viewed the part won't show and the original cap will look like the new cap. Installing the socket to the chock or the barrel.

Building the back part of the piece in integration with the top level spring or the lower springs and building the feet like they are as one with the spring, fixating the feet in the socket which is formed by going down towards the barrel.

Fixating the feet of the piece or the feet that go down as a consequence of the changes that are made, by enfolding the barrel instead of being placed into the socket.

Flipping the piece over so that the back part is produced in integration with the barrel, the chock or the lower springs and achieving fixation by protruding the feet and forming a socket.

Installing the back part of the piece between the lowest spring and the barrel, between the barrel and the chock, between the lowest spring and the chock or between the lower springs by the stud and the clamps, and fixating by inserting the feet in the socket that is formed above.

The same work can be completed with changes of shape and locations such as building two pieces and bringing together the feet and forming a socket or making fixations by bringing the feet together in the middle and installing the back part to on parts such as the springs, the barrel, chock and the plate as an original piece.
