A drive unit for an actuating device of a brake system. The drive unit includes: a motor housing; an electrical machine arranged in the motor housing, wherein a rotor of the electrical machine is arranged for conjoint rotation on a motor shaft mounted rotatably in the motor housing; and a planetary transmission by way of which the motor shaft is connected or connectable to an actuator element of the actuating device, wherein the planetary transmission has a rotatably mounted planet carrier, and wherein the planet carrier has a carrier portion on which at least one planet gear is rotatably mounted. The drive unit has an end plate arranged on the motor housing, by way of which end plate the planet carrier is mounted on a side of the planet gear facing away from the electrical machine.

Provided is an electric actuator which has fewer movable portions of a motion conversion mechanism so that slapping sound less liable to occur at the time of operation of an electric drive unit, and hence has quietness. An electric actuator includes: an electric driving source configured to generate a rotational motion as a driving force; and a motion conversion mechanism configured to convert the rotational motion to a rectilinear motion.

The motion conversion mechanism includes: a first member configured to be blocked to execute a rotational motion and a rectilinear motion; and a second member configured to engage with this first member to relatively rotate with respect to this first member, to thereby generate a rectilinear motion. This second member is configured to be rotationally driven by the driving force of the electric driving source.

An electric actuator includes a forwardly and reversely rotatable electric motor, a motion conversion mechanism configured to convert rotation of the electric motor into reciprocating linear motion of a screw shaft, an actuator case containing the electric motor and the motion conversion mechanism, and a boot covering a portion of the screw shaft that extends out of the actuator case. A vent is formed on the actuator case. The vent is configured to ventilate a sealingly closed space in the actuator case and the boot. A breathable waterproof member is provided on the vent and a cover member is also provided on the vent. The breathable waterproof member is configured to block entry and exit of water while permitting entry and exit of air. The cover member is configured to cover the vent so as to allow ventilation with outer air.

An electromechanical brake. The electromechanical brake includes an electromechanical actuating device which includes an electric motor, which interacts with a transmission, and a ramp mechanism, the ramp mechanism converting a rotational drive movement of the electric motor into a translational movement for applying a braking force. The electric motor and the transmission are arranged coaxially with each other and are at least partially surrounded by the ramp mechanism.

An electromechanical wheel brake for a motor vehicle, has an electromotive drive assembly designed to impinge a drive shaft with a torque. A transmission assembly transmits a torque acting on the drive shaft to an output shaft. A clamping device converts a torque acting on the output shaft into a clamping force acting along a clamping direction. A clamping force sensor system determines the clamping force generated by the clamping device. A control unit controls the drive assembly on the basis of a brake request and an applied clamping force. The drive assembly, the transmission assembly and the clamping device are each functional modules which can be checked for their respective function and, in the installed state, enter into operative connection via correspondingly designed interfaces. In the installed state of the wheel brake the interfaces establish a signal connection between the control unit and the clamping force sensor system.

A disc brake caliper has a caliper body arranged straddling a brake disc having a rotation axis defining an axial direction and opposite friction surfaces, pads accommodated in the caliper body, a cylinder forming a cylindrical wall and a bottom wall, a piston, and a parking-braking system having a rotating member accommodated within a rotation housing formed in the bottom wall. The cylinder defines a first annular housing and a second annular housing both made in the bottom wall, and extending in a direction transverse to the axial direction and leading into the rotation housing. The second annular housing is distinct from the first annular housing and positioned in a direction opposite to an inner surface of the bottom wall. The first annular housing accommodates a first seal. The second annular housing accommodates a second seal. The first and second seals act between the rotating member and the bottom wall.

This clutch control apparatus includes a clutch apparatus, a clutch actuator, and a release mechanism, wherein the release mechanism includes a release shaft that transmits a drive force of the clutch actuator to the clutch apparatus side, the release shaft is divided into: a clutch-side shaft that is supported by a clutch-side member as a separate body from the clutch actuator; and a control-side shaft that is supported by the clutch actuator and is attachable to and detachable from the clutch-side shaft, and the clutch actuator configures an integral actuator unit that includes the control-side shaft.

An electric braking device is an electric braking device in which a rotary motion of a rotation part is converted into a linear motion of a linear motion part, the electric braking device including a sleeve, and an urging part configured to urge a load sensor toward a caliper to which the sleeve is fixed, where the sleeve includes a rotation lock part configured to guide the linear motion of the linear motion part while preventing rotation of the linear motion part accompanying rotation of the rotation part, and a support part configured to support the urging part
