摘要： The invention concerns a control arrangement for an automatic electrohydraulically controlled transmission. In order to reduce expenditure on parts and assembly, the hydraulic control system and electronic control system are mounted directly adjacent each other and plug-in connections are provided between the solenoid valves of the hydraulic control system and the electronic control system. The hydraulic control system (20) substantially comprises two duct panels (28,30) in which control ducts, piston slides and solenoid valves (not shown) are disposed for controlling the conical plates and couplings of the transmission. The pressurized hydraulic fluid is fed directly into these duct panels from the pump (29). The electronic control system (22) has a single central connection (36) which is secured in the transmission housing cover (42) by an annular seal. Rotational speed sensors for the transmission shafts and temperature and pressure sensors are integrated into the control unit.

摘要： A change-speed transmission in the power train of a motor vehicle has a planetary gearing and coaxial radially inner and outer disc clutches, namely a direct clutch and a reverse clutch. At least that clutch which is engaged (i.e., in use) is cooled by a lubricant for the planetary gearing, and the flow of coolant to the clutches is regulated by the axially movable pressure plate of one of the clutches. A jet pump conveys lubricant from the sump in the transmission case into an axially extending channel of the input shaft of the transmission, and such channel forms part of a system of passages which supply coolant at least to that clutch which is then in use to transmit torque from the input shaft to an output element of the transmission.
