Abstract

The invention relates to a clutch device (500) of a vehicle transmission device (100), said clutch device (500) being located within a clutch bell housing (206) of a vehicle transmission and comprising a pneumatically controlled actuator device ( 208) connectable to the first clutch unit (202) of the vehicle transmission device (100) and arranged to controllably position said first clutch unit (202) between a closed position and an open position; the pneumatic controlled brake actuator means (210) connectable to a second clutch unit (204) of said transmission means and arranged to controllably switch said second clutch unit (204) in a closed position and open positioning between positions; and a valve unit (302) connected to said pneumatically controlled actuator device (208) and said pneumatically controlled brake actuator device (210), wherein said valve The unit (302) comprises a clutch valve (308) arranged in fluid communication with said pneumatically controlled actuator means (210) for controlling the flow of compressed air to said pneumatically controlled actuator means a supply of (210); and a brake valve (318) arranged in fluid communication with said pneumatically controlled brake actuator device (210) for controlling the supply of compressed air to said pneumatically controlled brake actuator Actuator device (210) supply.

Description

technical field [0001] The invention relates to a clutch device of a vehicle transmission. The invention also relates to a valve unit and a pneumatically controlled actuator arrangement. The invention is applicable to vehicles, particularly light, medium and heavy duty vehicles commonly referred to as trucks. Although the invention will be described primarily in relation to trucks, the invention is also applicable to other types of vehicles, such as construction machinery, buses and the like. Background technique [0002] Each of US2001 / 030097 and US2001 / 030096 discloses an actuation device for a friction clutch provided with a clutch valve unit comprising an actuation valve and a measurement sensor, wherein the clutch valve unit is controlled by An opening in the clutch housing is arranged and can be removed through the opening. In US2001 / 030097 the connection of the clutch valve unit appears to be arranged within the clutch housing. In US2001 / 030096 it is disclosed tha...
