In order to be able to carry out a fast pilot stroke up to the point at which the clutch makes contact, the piston-cylinder unit has a stepped piston whose first step of small diameter delimits, by means of its cylinder, a first pressure space, and whose second step of relatively large diameter delimits, by means of its cylinder, a second pressure space, a pressure line being connected to the first pressure space and, by means of a first non-return valve which opens at a certain pressure, to the second pressure space, and it also being possible for the second pressure space to be connected via a discharge line and a suction line, which contains a second non-return valve, to the fluid reservoir. The invention also relates to a drive device having clutches of said type.

    摘要: An actuator with a simple function for the control of a friction clutch in the drive train of a motor vehicle having a cylinder/piston unit for generating the contact pressure of the clutch should be fast, inherently safe and nevertheless simple and inexpensive. For this purpose, a controllable pump (3) generates a pressure medium and makes it available to the cylinder/piston unit (1) via a self-regulating valve unit (2). A dump valve (8) consists of a sleeve (10) and a spring-assisted slide (12) therein. The sleeve has a first opening (11), through which the pressure medium can flow from the cylinder/piston unit (1). The slide (12) exposes the opening (11) in a first position and conceals the opening of a second position. The clutch is controlled in this way by actuating the electric motor.

A second driveline for transferring torque to a second set of wheels includes a differential gearset having an output coupled to a second power disconnection device. A hypoid gearset is positioned within the second driveline in a power path between the first and second power disconnection devices. The second power disconnection device includes a clutch having a first set of clutch plates fixed for rotation with the differential gearset output. The clutch further includes a second set of clutch plates fixed for rotation with a shaft adapted to transfer torque to one of the wheels of the second set of wheels. A valve limits a flow of coolant to the clutch when the second power disconnection device operates in a disconnected mode.

    摘要: A vehicle drive train for transferring torque to first and second sets of wheels includes a first driveline adapted to transfer torque to the first set of wheels and a first power disconnection device. A second driveline is adapted to transfer torque to the second set of wheels and includes a second power disconnection device. A hypoid gearset is positioned within one of the first driveline and the second driveline in a power path between the first and second power disconnection devices. The hypoid gearset is selectively disconnected from being driven by the first driveline and the second driveline when the first and second power disconnection devices are operated in a disconnected, non-torque transferring, mode. At least one of the first and second power disconnection devices includes an active dry friction clutch.

    摘要: A coupling arrangement for a drive train of a motor vehicle includes at least one clutch arranged on a rotating shaft in order to couple the rotating shaft selectively with a drive element of the drive train, and at least one activation device to activate the clutch. The activation device is adapted to bring an engagement segment selectively into engagement with a threaded segment rotating with the shaft in order to cause a relative movement of the engagement segment and the threaded segment along the axis of the rotating shaft and thus activate the clutch in the axial direction.

    摘要: A transfer case arrangement may include a first output shaft, a second output shaft, a clutch, a shutdown device, a lubrication device, and a control. The clutch may distribute a torque between the output shafts. The shutdown device may shut down the second output shaft when the clutch is disengaged. The lubrication device may lubricate the clutch and/or another component of the transfer case arrangement. The lubrication device may include an oil conveying device for conveying lubrication oil. The control may activate the oil conveying device periodically when the second output shaft is shut down.
