Structural features and functions of shift fork of gearbox

  Many families have cars, but many people do not understand the internal structure and parts of the car. The gearbox shift fork is an indispensable part of the car. Today we will talk about the structural characteristics and functions of the part.

  Structural features:

  The shift fork foot of the transmission is stuck in the groove of the double gear. The shift control mechanism drives the shift fork and the shaft to slide in the transmission through the control groove at the head of the shift fork. The shift fork foot moves the double gear to slide on the spline shaft, so as to realize the speed change of the tractor.

  The main working surfaces of the shift fork of the transmission are the control groove and the two end faces of the shift fork foot. The main mating surfaces are Φ 15h8 hole Φ 5H12 hole and inner side of shift fork foot 50h12. The part is a special shape part, but the complexity is general. As the shift fork bears a certain force during operation, it is required to have a certain strength, stiffness and toughness.

  Function:

  The automobile needs a gearbox. When the automobile accelerates or decelerates, the existence of the gearbox can change the gear ratio between the engine and the driving wheel. By changing the gear ratio, the engine speed can be kept below the speed limit and close to the optimal performance speed range.

  Therefore, it is necessary to use the gearbox shift fork to change the meshing of gears at different gears, so as to realize the required gears and realize the movement of the car.
