  • Publication number: 20240410434
    Abstract: An electromechanical brake for a motor vehicle. The electromechanical brake includes a brake caliper forming a housing, in which is arranged a spindle drive that is drivable via a drive motor so that a brake piston is movable for applying an axial braking force. The brake caliper is formed in one piece and forms not only an axial support for the spindle drive but also a caliper body so that the braking force and a supporting force counteracting the braking force are absorbed by the brake caliper.

  • Publication number: 20240410435
    Abstract: An electromechanical brake for braking a motor vehicle. The electromechanical brake includes an electric motor having a shaft via which a brake piston can be axially moved for braking. A disk is arranged on the shaft and has a plurality of recesses arranged in the circumferential direction. In addition, the electromechanical brake includes a magnetic actuator which axially moves a pin so that one end of the pin interacts with the recesses of the disk and blocks a movement of the shaft in a brake release direction, whereby the pin can be held in a bistable manner. The magnetic actuator and a control unit, for controlling the electric motor and the magnetic actuator, are arranged in the axial direction relative to the electric motor, and the pin is movable parallel to the shaft.

  • Publication number: 20240151561
    Abstract: A sensor unit includes at least one sensor and at least two busbars. The busbars have first ends forming an internal electric interface for contacting the sensor and second ends forming an external electric interface for a connection cable or a plug receiving area. An injection-molded plastic housing defines the outer shape of the sensor unit and forms a sensor receiving area with a through-opening, which holds the sensor. The housing partly encases the busbars such that the internal electric interface is at least partly free and accessible near the sensor receiving area and the external electric interface is formed within the housing. The sensor and the internal electric interface are surrounded by a potting compound in a media-tight manner to form a sealed sensor head. The potting compound is formed of a material that can be processed at lower pressures and/or temperatures than the plastic material of the housing.
