DRIVE SET FOR ELECTRIC RAIL VEHICLES Russian patent published in 1999 - IPC

FIELD: transport engineering. SUBSTANCE: drive set has traction motor, mechanical transmission consisting of shaft-gear and large gear wheel, large gear wheel hub set into operation by traction motor by means of shaft-gear. Hollow shaft of transmission arranged at one side of wheelset axle enclosed the axle with clearance. Coupling serve as point of support and center of joint of drive set. Coupling permits cross and angular displacement from hub and provides transmission of torque from motor to side surface of one of wheelset wheels. Coupling consists of two halves one of which, arranged at hub side, is made with external toothed rim with round teeth meshing with teeth of second half of coupling. Wheels are of disk design, coupling sleeve of coupling is connected with inner side surface of disk wheel nearest to coupling. One half of coupling is connected with hub for detachment. EFFECT: facilitated mounting of coupling without press-fitting of wheel and bearings. 1 dwg
