Suspension device for motorized drive unit assembly of motor vehicle, has spring and damper interposed between support and motorized drive unit assembly, such that assembly oscillates with spring and damper to form mass of cylinder

摘要

The device has a support (3) integrated to a hub (2) of a ground connector of a vehicle. Slides (5) guide a motorized drive unit assembly (1) in rectilinear translation movement with respect to the support, such that the assembly is displaced along a straight path in a vertical plane. A transmission unit (9) i.e. epicyclic reduction gear, is interposed between the support and the assembly. A helical suspension spring and a damper are interposed between the support and the assembly, such that the assembly oscillates with the spring and the damper to form a mass of cylinder.
