THE LOCKING SYSTEM FOR STARTER PINION GEAR
TECHNICAL FIELD
The invention relates to locking system providing gears of starter motor, which is used for providing the first movement to the engine, to be turned only one direction, but when they are withdrawn they turn to idle in land vehicles. PRIOR ART
The starter motor is the part providing the first movement in automobiles. When the starter motor is worked at the first time, it means that when the ignition is switched on, starter pinion gear engages with flywheel attached to the crankshaft for transferring force of rotation produced by starter motor, to the crankshaft via flywheel.
In this way, the first movement is transferred to the engine. After transferring of the first movement, starter pinion gear leaves from flywheel. Starter pinion gear is locked to shaft transferring movement coming from starter motor and then starter pinion gear turns only one direction on this condition which enables flywheel to rotate. The locking operation isn't carried out when the starter pinion gear is withdrawn.
There are different locking mechanisms in the starter motor gear systems which are manufactured by using technic known today. The locking is provided by locking bearing on the body in these systems. The labour cost of this system is very high because of the body produced with locking bearing. The locking bearing will be worn out, because these systems have continuous working, which causes when the ignition is switched on, starter pinion gear can't transfer rotation power to the flywheel, attaching to crankshaft, inducing that the engine can't be worked and the battery can be discharged. BRIEF SUMMARY OF THE INVENTION
The invention relates to innovations of locking mechanism used in order to provide to transfer the first movement from starter pinion gear rotating one direction freely while it is prevented to rotate the other direction by locking mechanism in land vehicles.

The invention consists of these parts that are body (1), starter pinion gear (2), roller ball (3) and spring (4). The locking mechanism works in the body (1), which has at least two ball bearings (2.1) of the starter pinion gear (2).
In order to be transferred movement from starter motor to the flywheel via the starter pinion gear (2) when the ignition is switched on, the roller balls (3) in the ball bearing (2.1) of the starter pinion gear (2), which are in working position bearing (2.1.1) pass to the locking position bearing (2.1.2) owing to the movement from starter motor, for providing locking through locking surface (1.1 ) on the body (1 ), creating friction which makes the gear to be locked.
In this way, the movement is transferred to flywheel without any loss. The spring connection holes (2.1 .3) in the ball bearing (2.1 ) enables roller balls (3) connected with spring (4), to have controlled movement between working position bearing (2.1 .1 ) and locking position bearing (2.1 .2). When the locking operation is finished, it is very important that roller balls (3) should be returned back to working position bearing for maintaining continuous working.
The working position bearing (2.1.1 ) in the ball bearing (2.1 ) is structured as concave, that enables starter pinion gear (2) to rotate through roller ball (3) which doesn't contact with inner diameter of the body (1 ), thus, this situation prevents to occur any friction.
The locking position bearing (2.1 .2) in the ball bearing (2.1 ) is structured as convex, that enables starter pinion gear (2) to be locked through roller ball (3) which contacts with the inner diameter of the body (1), thus, this situation provides friction which enables locking for transferring movement to the flywheel.
The gear (2.2) can freely rotate backwards as long as roller balls (3) are in the working position bearing (2.1 .1 ) in the ball bearing (2.1 ).
