  • Parking gear for a motor vehicle
    Patent number: 6905004
    Abstract: 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.
    Type: Grant

  • Parking brake actuating device for a parking brake arrangement in a motor vehicle
    Patent number: 6655505
    Abstract: A parking brake actuating device includes a rotary lever arrangement in operative connection with a compensation device providing an idle path and a restoring element for controlling the rotary lever arrangement. The rotary lever arrangement controls the engagement of a blocking member with a counter-blocking member of the parking brake arrangement. The rotary lever arrangement has a rotary lever input part and a rotary lever output part and the idle path of the compensation device can be constructed so as to be in an operative connection between the rotary lever input part and the rotary lever output part.
