<p>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.</p> |
