  • Publication number: 20200282967
    Abstract: In order to offer an improved brake device without vacuum booster, in the case of which brake device the zero point of the cylinder piston remains as far as possible permanently within defined narrow tolerances and at the same time the impact noise is reliably reduced, it is proposed that the stop disk is elastically reversibly compressible in an axial direction over a defined compression travel and has the compression travel delimited, the delimitation being defined in a travel-controlled manner.

  • Patent number: 9868426
    Abstract: The invention relates to an electrically controllable pressure provision device (5, 5?), particularly for a hydraulic motor-vehicle brake system, comprising a stepped bore (54), which is arranged in a housing (53,21), and a piston (51), which can be actuated by an electromechanical actuator (35, 36). The piston (51), together with the housing (53, 21), delimits a pressure chamber (50). The piston (51) is constructed as a stepped piston, the smaller-diameter piston step (51?) of which enters the smaller-diameter step (54?) of the stepped bore after a specified actuation of the stepped piston, such that the pressure chamber (50) is subdivided into a first pressure chamber (55) and a second pressure chamber (56). The invention further relates to a brake system for motor vehicles having such a pressure provision device.

  • Patent number: 9180851
    Abstract: The invention relates to a master cylinder, in particular for a controlled motor vehicle brake system, including a first and a second piston which is displaceable in a housing and has a captive spring, a first end of the spring bearing at least indirectly against the piston and a second end thereof against a sleeve which is displaceable with respect to the piston and the movement of which with respect to the piston is limited by a pin provided on the piston and by a stop washer, the stop washer being arranged on a free end of the pin. In order to avoid impact noise upon rapid release of the brake, the stop washer of the first piston has a device for the damped abutment of the sleeve.

  • Publication number: 20120117961
    Abstract: A brake actuator unit for actuating a motor vehicle braking system of the “brake-by-wire” type, having a brake booster which can be actuated by a brake pedal and by an electronic control unit as a function of a driver's request and has a piston rod, a master brake cylinder arranged downstream of the brake booster, and a pedal travel simulator which interacts with the brake pedal and is arranged in parallel with the piston rod and by which, in the “brake-by-wire” mode, a restoring force acting on the brake pedal can be simulated independently of actuation of the brake booster. In order to decouple a force-transmitting connection between the brake pedal and the brake booster in the “brake-by-wire” mode, a distance ‘a’ is provided between the brake pedal and a component arranged downstream in the force flux and assigned to the brake booster.

  • Publication number: 20100251848
    Abstract: A brake booster for a motor vehicle brake system of the “brake-by-wire” type, which can be activated, on the one hand, by a brake pedal and, on the other hand, as a function of a driver's request, as well as independently of the driver's will by an electronic control unit, wherein the coupling of the brake pedal to an input element of the brake booster is embodied by a piston rod head provided with longitudinal guide openings, in such a way that a limited relative movement of the brake pedal is possible with respect to the input element, as a result of which, in particular in the “brake-by-wire” operating mode, decoupling of the force-transmitting connection between the brake pedal and the input element is ensured. The piston rod head is embodied as a U-shaped bent part which engages around the brake pedal.
