  • Patent number: 9976613
    Abstract: A disc brake runs wet by use of cooling fluid, in particular for a road vehicle, and includes stationary stator discs arranged in parallel to and at a distance from one other, and between which in each case a rotatable rotor disc is arranged. During braking, the radially extending stator discs and rotor discs can be pressed against one another, closing an air gap and, after the brake has been released, can be separated from one another, forming the air gap. The brake is designed such that the rotor discs have cooling channels which can be filled with cooling fluid immediately before or at the start of braking.

    Abstract: A method is provided for determining an air gap of a vehicle brake, in particular for a motor vehicle, wherein the vehicle brake includes a clamping device, a wear adjustment device, a sensor apparatus for detecting an actuation stroke of the clamping device, and a vehicle control system. The method performs the following steps: (S1) receiving a measurement signal of the actuation stroke, which measurement signal is provided by the sensor apparatus, within a previously specifiable time window during a braking process and storing the measurement signal as data pairs of actuation stroke and time during a braking process; (S2) calculating a time derivative of the measurement signal in the time window by a suitable algorithm in order to determine a point in time at a maximum; and (S3) determining the air gap on the basis of the point in time thus determined and forwarding the value of the air gap thus determined to the vehicle control system.

  • Patent number: 9810275
    Abstract: A sliding caliper disk brake is provided, in which a stationary brake carrier configured to carry a brake caliper includes two pairs of carrier horns, one pair of which supports a reaction-side brake pad and one pair of which supports an application side brake pad. The spacing between the reaction-side pair of carrier horns is larger than the spacing between the application-side pair of carrier horns. The reaction-side brake pad and reaction-side pair of carrier horns may be shorter than the corresponding application-side brake pad and carrier horns. The arrangement of the brake carrier, the brake caliper and the brake pads permits reduction in disk brake weight, cost and brake carrier stresses while providing desired brake thermal, mechanical and service life performance.
