US Patent 6905004 Parking gear for a motor vehicle

An engagement wheel is mounted so that it can rotate relative to the drive shaft of a drive train in a motor vehicle. To allow rotational driving, the engagement wheel is operatively connected with an element that cannot be rotated relative to the drive shaft by at least one elastically deformable element mounted in the torque path between the engagement wheel and the rotationally fixed element. The elastically deformable element can absorb residual rotational energy of the drive train, when the engagement wheel is locked by a locking element, which may be in the form of a pawl.
