WEIGHT TRANSFER-AND-DRIVING DEVICE Russian patent published in 2000 - IPC

FIELD: transport engineering; combination transport and transport-and-technological means. SUBSTANCE: proposed device is designed for use in aggregating. Weight transfer-and-driving device has hitch member connected with tractor mounting rods and coupled with mating member installed for rotation relative to horizontal and vertical axles on traction ring of semitrailer tow bar. Vertical axle is rigidly connected with horizontal bushing installed on support pivot and compensating gasket on hitch ring. Intermediate shaft intended for driving working members of transport-and-technological means is installed inside horizontal bushing. Upper rod of tractor mounting is made in form of hydraulic cylinder. Piston space of cylinder accommodates conical compression spring, and rod space accommodates limiting bushing press-fitted onto hydraulic cylinder rod. Length of bushing is calculated by formula. EFFECT: reduced labour input for connecting implements to tractor, enhanced reliability of operation of transport and technological means, reduced labour input for bringing weight transfer-and-driving device into action. 3 cl, 3 dwg
