VEHICLE DIFFERENTIAL LOCKING MECHANISM (DESIGN VERSIONS) Russian patent published in 1997 - IPC

FIELD: transport engineering. SUBSTANCE: shaft is made of coaxial semishafts coupled by three-member differential mechanism. According to first design version second and third members of differential are connected with corresponding ends of semishafts coupled by other ends through corresponding gear trains with differential output members, and first member is coupled through third and additional gear trains and two reversible overrunning clutches with rim of driven gear of drive transmitting torque to differential. According to second design version, one of semishafts is connected with both reversible overrunning clutches by means of which and corresponding gear trains it is coupled with one output member, other semishaft is coupled with other output member through other gear train. Third member of differential mechanism is coupled with above indicated rim by means of third gear train, and two others members are connected with ends of above-indicated semishafts. EFFECT: improved reliability of locking. 6 cl, 2 dwg
