Drive with partial elastic suspension, especially for electric motor vehicles.

摘要

The invention relates to a drive CUSHIONED IN PART, IN PARTICULAR FOR ELECTRIC TRACTION VEHICLES WITH A BIG WHEEL, which is mounted on the shaft with a GEARBOX closed and a small wheel, housed in the gearbox. ENGINE COUPLED fixed to the frame, and fixing GEARCASE TO FRAME is elastic damped by at least two elastic elements damped FITTED IN VERTICAL AND DIAMETRAL APPROXIMATE SENTIDOS the axis of the small wheel, whose lines of action PASSING THROUGH CENTER SHAFT small wheel. Want LIMITING THE DERIVATIVES DISADVANTAGES OF Oscillation BOX DRIVE ON THE SIDE OF CASTING OUT SHAFT PINION AND FIND A SIMPLE AND SATISFACTORY SOLUTION IN GENERAL FOR FIXING GEARCASE the frame with which it can be achieved, Without much while minimizing losses COST dEFORMATION COUPLING, AN ACTION STABILIZING THE QUEFAVOREZCA bearing life. To this end, it INTENDS TO ADJUST THE INVENTION A radial prestressing defined GEARCASE (3) with respect to the wheelset (4/5) by transverse elasticity of the damping elements (6). THAT IS SUITABLE RADIAL prestressing is adjusted by damper arrangement SUPPORT RUBBER SURFACES ABOVE AND BELOW GEARCASE (3).
