HYDRAULIC OPERATING DEVICE FOR OPERATING ACTUATORS IN A MOTOR VEHICLE TRANSMISSION

摘要

The invention relates to a hydraulic operating device (10) for operating actuators in a motor vehicle transmission, said device comprising at least two actuation cylinders (16), each containing a cylinder housing (18) and an actuation piston (22) guided therein along a cylinder axis (20) in a longitudinally displaceable manner, which actuation piston can be hydraulically loaded and is operatively connected to one of the actuators. The actuation cylinders are combined into a unit that can be flange-mounted on one side, via a flange face (24), to a dividing wall of a transmission housing of the motor vehicle transmission. To this end, the cylinder housings are injection moulded from plastic integrally with a flange plate (28) that runs transversely to the cylinder axes, the flange face being formed on the flange plate. The cylinder housings protrude beyond the flange plate, at least on the side of the flange face, in the direction of the cylinder axes, such that the installation space requirements for the operating device in or on the transmission housing are minimal.
