Release apparatus for pull-type friction clutches

摘要

A release apparatus for a pull-type friction clutch wherein the coupling between the parts on the engine and the parts on the power train of a motor vehicle is automatically deactivated in response to separation of the engine from the power train, and is automatically reestablished during reassembly of the engine with the power train. The coupling employs a detent in the form of a resilient split wire ring which is carried by the parts on the engine or by the parts on the power train, and a complementary undercut member which is carried by the parts on the power train or by the parts on the engine and form-lockingly engages the detent when the two sets of parts assume predetermined axial positions relative to each other. A releasing device is provided on one set of parts to depress the detent into a socket in response to movement of the engine and the power train away from each other to thus deactivate the coupling.
