  • Patent number: 11387751
    Abstract: A device for speed-dependent braking torque control for electrical machines excited by permanent magnets includes a switching device deliberately short-circuits the electrical machine. The switching device is controlled as a function of an induced voltage generated by the electrical machine. If the induced voltage falls below a defined value, the switching device reverses the short-circuited state of the electrical machine to cause the braking torque to reduce to zero and the speed to increase again. The speed can thus be controlled within a range by alternately opening and closing the switching device.

  • Patent number: 11378585
    Abstract: A method for determining a speed between a measurement-sensor, including at least one coil and a ferromagnetic-transmitter-element (FEM), including: changing the inductance of the coil and the voltage induced therein, in a vehicle using an inductive-speed-sensor having at least the coil and FEM; recording the inductance-change of the coil, and determining the speed based on the changed-inductance; in which the inductance-change is recorded and the speed is determined based on the changed-inductance only until the determined-speed has reached a speed-limit-value (SLV) starting from lower-speeds, in which a voltage-change induced in the coil is recorded and the speed is determined based on the changed-voltage when the determined-speed has exceeded the SLV starting from lower-speeds, and in which an inductance-change is recorded and the speed is determined based on the changed-inductance when the determined-speed has reached/dropped below the SLV starting from higher-speeds.

  • Patent number: 11359684
    Abstract: A disc brake for a commercial vehicle is provided. The disc brake includes a brake caliper, preferably in the form of a sliding caliper, straddling a brake disc, being arranged on a fixed backing plate, and having an application device for applying the brake. The disk brake also includes two brake pads, each having a pad carrier and an affixed friction pad, and each being inserted into a pad shaft of the backing plate. The brake caliper has a central caliper opening over the disc brake. A hold-down bar is provided, designed in such a way that, of the two brake pads, it radially secures only the reaction-side brake pad in its lining shaft in the backing plate. The hold-down bar is held on the brake caliper by its end facing away from the brake pad. Additionally, the application-side brake pad is radially interlockingly secured in its pad shaft in the backing plate.

  • Patent number: 11255390
    Abstract: A brake caliper is fastened to a stationary brake carrier by two fastening elements such that the caliper can slide axially relative to the brake disc. The fastening elements each have a guide bar fixedly connected to the brake carrier, of which guide bars, one guide bar is guided as a fixed bearing and the other guide bar is guided in a plain bearing, which is designed as a floating bearing having a floating bearing axis. The floating bearing has a guide bush, which reaches around the guide bar and is retained in a caliper bore such that sliding is prevented. A first tubular, variable-length seal is arranged on the end region of the guide bar far from the brake disc, which seals the guide bar from the environment and is fastened on the guide bar and in the guide bush. The first tubular, variable-length seal is clamped on the guide bar by a cap pressed into the guide bar.
