Mechanical engageable and disengageable coupling for use in automobiles for selective transmission of torque acting on rotatable drive axle to rotatable output axle, has axial spring tongues, which are axially pushed-in or pushed-out

摘要

The mechanical engageable and disengageable coupling has axial spring tongues (4), which are axially pushed-in or pushed-out from the axial grooves of an output axle (3). The spring tongues are connected to the walls of the grooves in a force transmitting manner in the pushed-in state. The spring tongues unlatch from the grooves during overtorque. The number of spring tongues is less than the number of grooves.
