摘要： A drivetrain for a motor vehicle has a friction clutch for transmitting drive torque for the motor vehicle and has an actuator arrangement for actuating the friction clutch. The actuator arrangement has a first actuator which is designed to close the friction clutch quickly with little force expenditure in order to thus quickly close up the play which is present in the open state of the friction clutch. The actuator arrangement has a second actuator which is designed such that, with a small stroke, it applies a large force for actuating the friction clutch in order to keep the friction clutch closed with little energy expenditure.

摘要： The hydraulic coupling according to the present invention generally includes a multi-plate clutch assembly operatively connecting a pair of rotary members, an actuator assembly for actuating the clutch assembly, and a fluid control system operable for controlling actuation of the actuator assembly. The actuator assembly includes a hydraulic pump and a piston mounted in a piston chamber for movement relative to the multi-plate clutch assembly. The fluid control system regulates the fluid pressure supplied to the piston chamber by the hydraulic pump to control the clutch engagement force exerted by the piston on the clutch assembly. The fluid control system includes an electrically-controlled flow control valve operable for regulating the fluid pressure delivered to the piston chamber. Preferably, the flow control valve is a pulse-width modulated (PWM) valve having a moveable valve element. The position of the valve element is controlled by an electronic traction control module that monitors and responds to certain vehicle operating conditions, including a sump fluid temperature, a coupling outlet oil temperature, the four wheel speeds, and the piston chamber pressure. The electronic traction control module sends a control signal to the PWM control valve for modulating the hydraulic pressure supplied to the piston chamber, which, in turn, controls clutch engagement.

摘要： Disclosed is a clutch changeover circuit suitably used for a multi-stage stationary non-stage transmission. Valve bodies of pressure regulating valve (211, 221, 231, 241) are respectively provided with throttle passages (311, 321, 311, 341) communicating therewith in such a manner that hydraulic oil flows to the clutch sides when they are closed, since the sliding of the clutches or damage thereto can occur if pressure regulating valves having good override characteristics are used. Accordingly, at the time of changing over the clutch, since hydraulic oil flows at least by a portion corresponding to the rate of flow of leaking oil, it is possible to prevent the clutches from sliding or becoming damaged while using regulating valves having good override characteristics. In addition, the circuit is provided with common oil passages (301, 302) leading to a plurality of clutches corresponding to speed stages that are not adjacent to each other, and pressure regulating valves (411, 421) and pressure reducing valves (412, 422) that are used jointly for the plurality of stages are provided in these common oil passages, thereby simplifying the circuit configuration by reducing by half the number of these conventionally employed valves.

摘要： The present teachings provide for a power transmitting component including a friction clutch, a reservoir, a hydraulic ram to actuate the clutch, a motor, and first and second pumps simultaneously driven by the motor. The first pump is in fluid communication with the reservoir and the ram. The first pump is configured to provide hydraulic fluid to the ram when the motor rotates in a first direction. The second pump is coupled to the reservoir and provides hydraulic fluid to the ram when the output shaft rotates in the first direction and a pressure differential between the ram and the second pump is less than or equal to a predetermined pressure differential. The second pump has a displacement greater than the first pump and is configured to provide hydraulic fluid to the ram at a lower pressure and higher flow rate than the first pump.

摘要： A torque transfer coupling includes first and second rotary members. A transfer clutch operatively connects the first and second rotary members. A piston, disposed in a piston chamber, is actuable to engage the transfer clutch. A hydraulic pump in fluid communication with a sump containing hydraulic fluid has a first pump member fixed for rotation with the first rotary member and a second pump member fixed for rotation with the second rotary member such that relative rotation between the first and the second pump members generates a fluid pumping action. A first flow path supplies hydraulic fluid from the hydraulic pump to the piston chamber. A second flow path supplies hydraulic fluid from the piston chamber to a control valve for regulating the pressure of the hydraulic fluid supplied to the piston chamber. The second flow path includes an aperture extending through the second pump member.
