AXLE-SHAFT STEERING TRANSMISSION Russian patent published in 1995 - IPC

FIELD: automotive industry. SUBSTANCE: device provides transmission coupling between axle-shaft power unit and wheel playing the part of automatic clutch and ensuring free rolling and regenerative and friction braking. Offered complex of original developments provides: bringing clutch plate 13 behind wheel disk with its periodical operation in power flows from engine to wheel and from this wheel to idling engine with self-change for free rolling between working modes; installation of axle-shaft steering transmissions on front and rear axles of automobile with independent power units; one-track rolling of wheels at cornering with maximum total angle of 50 degrees and possibility of using power units separately, depending on conditions and type of terrain. Taking into account the fact that constant-velocity ball universal joints widely used in modern transmissions feature undesirable pushing-apart forces which cause undue wear of contact surfaces and bearings and ball joints of supports, invention offers three-trunnion constant-velocity universal joint which has no above-indicated disadvantages and provides compact mechanical coupling contributing to implementation of promising and economically profitable vehicle of new generation. EFFECT: perfection of design development, reduced materials usage, cut down consumption of energy, higher ecological standards, possibility of implementation of unitilized reserves. 7 cl, 2 dwg
