GEARSHIFT MECHANISM WITH CAM CLUTCH Russian patent published in 2024 - IPC B60K17/08 

FIELD: machine building.

SUBSTANCE: gearshift mechanism comprises a ring-shaped clutch mounted on a smooth cylindrical surface of a sliding gear clutch. Cam clutch is supported and centered relative to it. On one half of the outer surface of the cam clutch there is a toothed sector. On the second half on the side surfaces there are cuts forming the surface of cams, which are a helical surface with three straight sections. Lateral surfaces of the cam clutch represent a stepped surface; these surfaces run in parallel on one side and the other side. On the inner surface of the cam clutch on the edge there is a projection in the form of a sector, and on the opposite edge there is a removable plate in the form of a sector, made for fixation of the cam clutch in the axial direction relative to the sliding gear clutch. Guide thrusts with sharpened tips, which are fixed on the gearbox housing, adjoin the side surfaces of the cams. Drive gear of the last stage of the drive reduction gear, the axis of which is fixed in the gearbox housing, is engaged with the toothed sector of the cam clutch, the reduction gear receives rotation from the stepper motor of the gearshift mechanism.

EFFECT: higher efficiency.
