FIELD: mechanical engineering and transport; automobile winch for self-recovery of automobiles and pulling loads at loading. SUBSTANCE: winch has intermediate shaft of mechanical drive, wire rope drum mounted on bearing support installed in winch housing and wave-type reducer installed coaxially with drum. Winch has friction train between wire rope and intermediate shaft to transmit rotation from drive to drum. Intermediate shaft is made in form of polyhedral detachable shaft passing through similar holes of bushing press-fitted into engine crankshaft jaws. According to first design version driven gear of wave generator reduction gear is coupled with wire rope drum through tubular shaft passing inside cantilever-mounted bearing support square to which vertical roller of wire rope layer is installed on winch housing. According to second design version, second end of intermediate shaft is fitted in hole of inner holder of centrifugal coupling. According to first design version, one end of wire rope is secured on grouser and is tensioned at side of other end.
