摘要： A drive force transfer device that includes a friction clutch with improved response at the time when the friction clutch is pressed by a hydraulic pressure is provided. A drive force transfer device has: a clutch drum; an inner shaft; a friction clutch that has a plurality of outer clutch plates that are rotatable together with the clutch drum and a plurality of inner clutch plates that are rotatable together with the inner shaft; a piston that receives a hydraulic pressure supplied to a cylinder to press the friction clutch; and a hydraulic circuit that supplies the cylinder with working oil. The hydraulic circuit has a first pump portion that supplies the cylinder with the working oil, and a second pump portion that supplies the cylinder with the working oil at a pressure that is higher than that of the working oil supplied by the first pump portion.

摘要： A hydraulic system for a vehicle clutch assembly can include a pump and a purge valve for regulating hydraulic pressure supplied to the clutch. The hydraulic pressure at the pump can be set to a value higher than the operating pressure for the clutch. The purge valve can be configured to purge hydraulic pressure from the hydraulic system so that an optimum, controllable, and/or pre-determined operating pressure can be supplied to the clutch. The system can be configured to provide accurate control of the clutch(es), continuous cooling capacity to the hydraulic system components, lateral torque control when two separate hydraulic circuits are used, weight and cost reduction of the vehicle clutch, as well as other vehicle functions and characteristics.

摘要： An automated mechanical transmission system for use in commercial vehicles comprises an oil spray type oil hydraulic clutch, a mechanical transmission having a shift cylinder, a shift valve, a select cylinder, and a select valve, a hydraulic system control circuit, a clutch oil spray circuit, and a clutch/transmission select valve. The oil hydraulic clutch includes an oil hydraulic clutch servo cylinder for sandwiching a clutch disk between a pressure plate and a clutch cover, the system control circuit includes a high pressure side and a low pressure side hydraulic clutch control lines connected with the clutch servo cylinder, and a hydraulic transmission control line connected with the shift cylinder and select cylinder through the shift valve and select valve. A pressure control valve actuated by a pressure control pilot valve is disposed at the low pressure side hydraulic clutch control line. The pressure control valve adjusts oil pressure of the oil hydraulic circuit to connect or disconnect the clutch, thereby to gear shift the transmission. An oil spray control valve is disposed in the clutch oil spray circuit and controls the flow rate of oil displayed to the clutch disk spray according to each state of the clutch.

摘要： A clutch control hydraulic circuit includes first and second solenoid valves connected to a control unit, the first solenoid valve is provided between a first hydraulic pathway and a downstream junction hydraulic pathway normally switches to an open state when not energized, and switches to a closed state when energized; and the second solenoid valve is provided between a second hydraulic pathway and the junction hydraulic pathway, switches to a closed state when not energized, and switches to an open state when energized. The first solenoid valve maintains its closed state when switched to a non-energized state from an energized state while pressure of the junction hydraulic pathway is higher than that of the first hydraulic pathway, and when the first solenoid valve is thus closed in its non-energized state, pressurizing the upstream side hydraulic pathway by operation of a clutch lever opens the first solenoid valve.

摘要： A vehicle clutch hydraulic system for a vehicle is provided with a mechanical oil pump, an electric oil pump, a forward clutch and a control valve unit. In the vehicle clutch hydraulic system, a main pump oil passage fluidly connects the mechanical oil pump to the control valve unit. A sub-pump oil passage fluidly connects the electric oil pump to a forward clutch oil passage into which an oil passage outlet opens at an inside location closer to a clutch rotational axis than a clutch oil chamber of the forward clutch.
