摘要： A hydraulic brake and electronic parking integrated caliper includes a base, a main body movable relative to the base, two brake pads movable relative to the main body, two hydraulic pistons for pushing the brake pads, an electronic drive fixed to the main body, a threaded rod driven by the electronic drive to rotate, and a linearly displacing member displaceable relative to the threaded rod. When moving from a first position to a second position, the linearly displacing member pushes a hydraulic piston and a brake pad toward a direction to press against a brake disc. When moving from the second position to a third position, the linearly displacing member moves the threaded rod, electronic drive and main body toward another direction to make the other hydraulic piston and brake pad press against the brake disc. The caliper has simple structure and generates larger clamping force.

摘要： A ball-screw drive (16) for an actuator assembly (10) of a vehicle brake is indicated, comprising a rotatably mounted recirculating ball screw (18) on which a cup-shaped screw nut (20) is mounted. On the circumferential surface of the recirculating ball screw (18), at least one thread (26) is formed, and on the inner surface of the screw nut (20), a corresponding thread (28) is formed, wherein, in the threads (26, 28), a plurality of balls (30) are guided in such a way that a rotation of the recirculating ball screw (18) brings about an axial displacement of the screw nut (20) along an axis of rotation of the recirculating ball screw (18), The screw nut (20) is formed in two parts and has an inner part (36), in which the thread (28) is formed, and an outer part (38), on which the circumferential surface (34) of the screw nut (20) is formed, wherein the outer part (38) has protection against corrosion. Furthermore, an actuator assembly (10) and a method for producing a ball-screw drive (16) are indicated.

摘要： A ball screw drive for an actuator assembly of a vehicle brake is disclosed, comprising a rotatably mounted ball screw shaft on which a ball nut, which is open axially on one side, is mounted, wherein at least one thread is formed on a circumferential face of the ball screw shaft and a corresponding thread is formed on an inner face of the ball nut, wherein a large number of balls is guided in the threads in such a way that rotation of the ball screw shaft causes axial displacement of the ball nut along an axis of rotation of the ball screw shaft. The ball nut has a corrosion protection coating on an exterior thereof, at least on an end face thereof and in a region of a circumferential wall adjacent to the end face. A method for producing a ball screw drive is disclosed.

摘要： Provided is an electric parking brake device in which an actuator case of an electric actuator is mounted to a backplate of a drum brake which includes a parking brake lever, with which electric actuator it is possible to obtain a parking brake state by pulling a brake cable linked with the parking brake lever. The backplate is formed with a through-hole for passing the brake cable and has a connecting tube portion integrally protruding therefrom and enclosing the through-hole. A mounting tube includes, on one end in an axial direction, a joint portion which is formed separately from the backplate and joined to the connecting tube portion. The actuator case is mounted to the mounting tube at certain axial and circumferential positions with respect to the mounting tube. This allows increased freedom of the mounting attitude of the electric actuator with respect to the backplate without increased cost.
