  • Patent number: 8795136
    Abstract: An actuating device includes a vehicle operating brake and parking brake. A first braking effect is generated by the parking brake independently of a braking procedure for the operating brake. The actuating device comprises a first switched state, wherein the first braking effect of the parking brake cannot be provided, and a second switched state, wherein the first (full) braking effect of the parking brake is provided. The actuating device further comprises a manually actuatable operating element for actuating the parking brake that comprises travel positions. The actuating device is switched to the second switched state in a first travel position when the parking brake is released, and to the first switched state when the parking brake is applied. Also, the actuating device is switchable to a further switched state. In an actuating method, the actuating device is switched to the further switched state in response to an actuation.

  • Patent number: 8290679
    Abstract: An electrically controlled brake system for a tractor is provided that is equipped with an anti-jackknifing brake that can be actuated by means of a manual operating element and that acts only on the brakes of a trailer coupled to the tractor. The operating element is an electrical element which generates an electrical signal to control a valve device by means of which the braking force of the anti-jackknifing brake can be increased.

  • Publication number: 20120006634
    Abstract: The invention relates to an actuating device for a parking brake of a vehicle, in particular a commercial vehicle, wherein the actuating device comprises an operating brake for driving operation and the parking brake for securing the vehicle. A first braking effect can be generated by means of the parking brake for the vehicle independently of a braking procedure for the operating brake. The actuating device comprises a first switched state, wherein the first braking effect of the parking brake cannot be provided, and comprises a second switched state, wherein the first, in particular full, braking effect and the parking brake can be provided.
