ELECTROMECHANICAL BRAKE DEVICE WITH A COMPACT LINEAR ACTUATOR

原文（中国語）

An electromechanical brake device with a linear actuator for moving a brake piston in an electromechanically operable wheel brake of a motor vehicle, and to a motor vehicle having an electromechanical brake device of this type. The electromechanical brake device has an actuator unit wherein the actuator unit comprises a rotational-translational movement converter having a piston movable in an axial direction and a spindle wherein the spindle is hollow at least in portions, to at least partially define a cavity, a force transmission unit, which comprises a planetary gearbox with a sun gear, planet gears, a planet carrier and a ring gear, and an axial bearing located in the cavity for absorbing axial forces occurring during brake application. The electromechanical brake device herein can also comprise a force sensor.
