An actuator includes a controller, a motor and a sensor device. The controller includes a housing, and the motor includes a rotor, and the rotor includes a rotating shaft. The motor is mounted on the outside of the housing, and the sensor device includes a magnet and a sensor, the magnet is mounted on the rotating shaft of the motor, and the sensor is mounted inside the housing. The actuator has a good waterproof performance and anti-interference ability. This disclosure also relates to an electronic clutch system having the actuator.

A hydrostatically operated clutch system having a hydrostatic clutch actuator for hydrostatically operating a clutch, in particular a pulse separation clutch of a hybrid drive, such that the hydrostatic clutch actuator is combined with a valve arrangement which is to be opened actively and enables the clutch to be engaged rapidly.

Clutch for a motor vehicle, preferably for engaging and disengaging a drivetrain for all-wheel drive vehicles, comprising a first shaft, a second shaft coaxially arranged with the first shaft, a clutch sleeve, which is displaceable in an axial direction relative to the first shaft and the second shaft and which brings about a positive coupling or decoupling of the first shaft and the second shaft, together with a coil to which current can be applied, wherein the clutch sleeve is arranged, torsionally fixed to the first shaft, and wherein the coil to which current can be applied is arranged coaxially with the axial direction, wherein the clutch sleeve to which current can be applied can be displaced in an axial direction through the application of current to the coil.

A vehicle includes an engine, a manual transmission, and a clutch that selectively couples the engine to the transmission. The clutch includes a disk biased to engage a flywheel of the engine, a first actuator that disengages the disk in response to depression of a clutch pedal, and a second actuator that disengages the disk in response to an electric signal from a vehicle controller.
