A self-cleaning mechanism for a pneumatic central clutch release includes: a release piston which is coaxially arranged around a hollow shaft and is mounted such that it moves in the direction of an axis of the hollow shaft; and a housing which at least partially surrounds the release piston so as to form a pressure chamber between the hollow shaft, the housing and the release piston, which is sealed from the environment and can be connected to a fluid pressure source; and a cleaning chamber fluidically arranged between the pressure chamber and the environment. The cleaning chamber is able to be connected to the environment by way of a ventilation channel.

Self-cleaning mechanism for pneumatic central clutch release

A clutch actuator transmitting a disengaging force to a clutch disengaging device of a includes an actuating element which receives the disengaging force, and a piston rod for transmitting the disengaging force from the actuating element to the disengaging device. The piston rod bears against an actuating element connection region such that the piston rod is movable towards the connection region by the reaction force of the clutch. The positioning of the connection region and the piston rod relative to each other due to the movement can be fixed by applying the disengaging force to the actuating element. The actuating element at least partly deflects the disengaging force, producing a normal force and/or a radial force acting between the connection region and the piston rod. The normal force and/or the radial force fixes the position of the connection region and the piston rod relative to each other.

A sensor device is provided for detecting a shifting position of a vehicle transmission. The vehicle transmission includes a transmission chamber, in which transmission elements are arranged. The sensor device includes a bar element, which extends from the transmission chamber into a secondary chamber sealed off from the transmission chamber and is arranged such that the bar element can be moved in dependence on the shifting position. The bar element has an interface arranged in the transmission chamber for coupling the bar element to a transmission element positioned in dependence on the shifting position and an accommodating segment arranged in the secondary chamber. The sensor device also has a transducer element, which is attached to the accommodating segment of the bar element. The sensor device also has a detecting device for detecting a position of the transducer element depending on the shifting position or a motion of the transducer element depending on a change in the shifting position.
