The present invention relates to a clutch arrangement (500) of a vehicle transmission arrangement (100), the clutch arrangement (500) being positioned within a clutch bell housing (206) of the vehicle transmission and comprising a pneumatically controlled actuator arrangement (208) connectable to a first clutch unit (202) of the vehicle transmission arrangement (100) and arranged to controllably position the first clutch unit (202) between a closed position and an opened position, a pneumatically controlled brake actuator arrangement (210) connectable to a second clutch unit (204) of the transmission arrangement and arranged to controllably position the second clutch unit (204) between a closed position and an opened position, and a valve unit (302) connected to the pneumatically controlled actuator arrangement (208) and the pneumatically controlled brake actuator arrangement (210), wherein the valve unit (302) comprises a clutch valve (308) arranged in fluid communication with the pneumatically controlled actuator arrangement (210) for controlling supply of compressed air to the pneumatically controlled actuator arrangement (210), and a brake valve (318) arranged in fluid communication with the pneumatically controlled brake actuator arrangement (210) for controlling supply of compressed air to the pneumatically controlled brake actuator arrangement (210).
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 valve unit for controlling the flow of pressurized air to a pneumatically controlled actuator arrangement and a pneumatically controlled brake actuator arrangement of a vehicle transmission arrangement, the valve unit being connectable to a source of pressurized air and comprises a clutch valve arranged to be provided 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 to be provided in fluid communication with the pneumatically controlled brake actuator arrangement for controlling supply of compressed air to the pneumatically controlled brake actuator arrangement.
A pneumatically controlled actuator arrangement of a vehicle transmission arrangement, said actuator arrangement being 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, the actuator arrangement being connectable to a valve unit arranged to controllably supply pressurized air to the actuator arrangement wherein the actuator arrangement comprises an interface portion for connection to the valve unit, said interface portion comprises a mechanical interface portion and a pneumatic interface portion, wherein the mechanical interface portion comprises guiding means for guiding a portion of the valve unit for connection to the actuator arrangement.
