  • 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.

  • Patent number: 11105386
    Abstract: A brake caliper device is adapted to be used with a brake disk, and includes a main body unit, first and second pads, and a caliper actuator unit. The caliper actuator unit includes an actuating member, a bolt member that abuts against the actuating member, and a threaded sleeve that is threadedly engaged to the bolt member. When the actuating member is driven by an external force, the actuating member is capable of vibrating axially to cause an axial vibration of the bolt member, which prompts the threaded sleeve to rotate relative to the bolt member for pushing the first pad toward the brake disk, thereby automatically providing a travel stroke that compensates for pad wear.
