Abstract
The device is for a motor-drive unit 1 suspended elastically on the structure 5 of a vehicle. The device comprises reverse speed and forward speed abutments 11, 12 of low flexibility which are each interposed between two bearing elements of which one is connected to the support 6 of the unit 1 and the other is connected to a support 16 which is part of the structure 5. One, 18, of the bearing elements of at least one, 12, of the abutments is mounted to be movable relative to its support 16 and is maintained spaced from the latter by a predetermined distance J in a direction perpendicular to the axis of rotation of the unit 1, by means of a highly flexible pre-stressed spring 20. By means of this arrangement, when the gearbox is engaged with a front speed ratio and the vehicle remains stationary, the transmission to the structure 5 of the vibrations of the unit 1 through the forward speed abutment 12 is prevented.
