Abstract
A brake actuator (1, 1′) includes a casing (10), an electric motor for providing a driving torque, a cam disc (20) rotatably mounted to the casing (10) and operatively coupled to the electric motor, and a push rod (30) received in the casing (10), and configured to reciprocate in a longitudinal direction (100) between a retracted position (300) and an extended position (400). The push rod (30) and the cam disc (20) are operatively coupled such that a rotational movement of the cam disc (20) causes a linear movement of the push rod. A guiding member (40), in particular a bushing, is mounted to the casing (10), wherein the guiding member (40) guides the movement of the push rod (30) in the longitudinal direction (100).
Claims19
A brake actuator (1, 1′) comprising:
- a casing (10),
- an electric motor for providing a driving torque,
- a cam disc (20) rotatably mounted to the casing (10), wherein the cam disc (20) is operatively coupled to the electric motor,
- a push rod (30) disposed in the casing (10), the push rod configured to reciprocate in a longitudinal direction (100) between a retracted position (300) and an extended position (400),
- wherein the push rod (30) and the cam disc (20) are operatively coupled such that a rotational movement of the cam disc (20) causes a linear movement of the push rod,
- wherein a guiding member (40) is mounted to the casing (10), wherein the guiding member is a bushing;
- wherein the guiding member (40) is configured to guide movement of the push rod (30) in longitudinal direction (100);
- wherein the guiding member (40) has at least one slot (43) extending in the longitudinal direction (100).
