摘要:
The invention relates to measures for controlling or reducing drag torque occurring in a multi-plate clutch device (202) due to temperature-related increased viscosity of an operating fluid which is supplied to the plates in operation. The aim of the invention is to enable a motor vehicle to be started or operated even at low temperatures. According to one aspect of the invention, a motor vehicle comprising a drive train is especially provided. Said drive train comprises a drive unit (238), a gearbox (330) having a first gearbox input shaft and a second gearbox input shaft, and a clutch (202) having a first clutch device which is associated with the first gearbox input shaft, and a second clutch device which is associated with the second gearbox input shaft, for transferring torque between the drive unit and the gearbox. Said clutch devices are embodied in the form of plate clutches to which an operating fluid can be supplied, especially a cooling oil, in order to operate the same. Said gearbox (330) is associated with an actuator device and a control device (316) for controlling the actuator device, the arrangement of which enables the gears associated with the first and second gearbox input shafts to be engaged and disengaged. According to the invention, the control device (316) is designed in such a way that at least one gear is automatically engaged by means of the actuator device (236), as a result of the clutch release of the vehicle.

摘要:
The invention relates to a clutch system, comprising at least one clutch device, especially for arrangement in a drive train, between a drive unit and a transmission. Said clutch device (202) can be actuated through the conveying of a pressure medium and/or is able to operate under the influence of an operating medium. One aspect of the invention provides that a secondary medium that acts as the pressure medium for actuating or as the operating medium for operating the clutch arrangement is supplied by a pump arrangement (208) which supplies a primary medium and a secondary medium supply device (220) which is connected to the pump arrangement or a secondary pump arrangement (220). Said secondary medium supply arrangement or secondary pump arrangement has the following: at least one pressure absorption element which is movably arranged in a housing, which during operation, is exposed to the primary medium that is supplied by the first-mentioned pump arrangement, on at least one pressure absorption surface, and which can be caused to move by conveying the operating medium; and at least one interactional element which is movably arranged in the/a housing, which is motionally coupled to the pressure absorption element, which during operation, interacts with the secondary medium on at least one interactional surface, and whose action enables the supply of the secondary medium, optionally by displacement and/or introducing an acceleration and/or introducing a swirl.
