A transmission includes a first component and a second component which are journaled for rotation relative to each other, and a locking mechanism for rotationally locking the first component and the second component relative to each other in a predetermined mutual rotation position. The locking mechanism includes a sleeve and a dog clutch, the sleeve being rotationally locked relative to the first component and the dog clutch being rotationally locked relative to the second component, the sleeve and the dog clutch being axially displaceable relative to each other for engagement of the sleeve and the dog clutch such that the first component and the second component are rotationally locked relative to each other, the sleeve and the dog clutch being engageable only in a mutual rotation position corresponding to the predetermined mutual rotation position of the first component and the second component.

Transmission

A transmission for a vehicle. The transmission includes a housing and a valve block arranged in the housing, and a parking lock mechanism. The parking lock mechanism has a wheel rotationally locked to a shaft of the transmission, a pawl and a hydraulic actuator arranged for engagement of the wheel and the pawl for locking the shaft. The actuator is hydraulically connected to the valve block such that the actuator is supplied by hydraulic fluid from the valve block.

Transmission for a vehicle

The present invention relates to a clutch arrangement () of a vehicle transmission arrangement (), the clutch arrangement () being positioned within a clutch bell housing () of the vehicle transmission and comprising a pneumatically controlled actuator arrangement () connectable to a first clutch unit () of the vehicle transmission arrangement () and arranged to controllably position the first clutch unit () between a closed position and an opened position, a pneumatically controlled brake actuator arrangement () connectable to a second clutch unit () of the transmission arrangement and arranged to controllably position the second clutch unit () between a closed position and an opened position, and a valve unit () connected to the pneumatically controlled actuator arrangement () and the pneumatically controlled brake actuator arrangement (), wherein the valve unit () comprises a clutch valve () arranged in fluid communication with the pneumatically controlled actuator arrangement () for controlling supply of compressed air to the pneumatically controlled actuator arrangement (), and a brake valve () arranged in fluid communication with the pneumatically controlled brake actuator arrangement () for controlling supply of compressed air to the pneumatically controlled brake actuator arrangement ().
