Automatic locking gear for four wheeled drive vehicle - has compressible bearing between static and driven race urging cam into locking engagement with locking member

摘要

The automatic mechanical clutch assembly has a shift mechanism which is directly responsive to torque applied to a driving member. This advances driven member into position for locking engagement without the necessity of interlocking elements being brought into alignment with one another. This is accomplished by coacting complementary cam portions between movable and normally fixed actuating members. The cam portions on the movable actuating member rise and are axially displaced so as to shift the drive gear into position for intermeshing engagement with a driven gear.
