20100240465 | SHAFT ARRANGEMENT FOR A TRANSMISSION - A shaft arrangement for a transmission comprises a shaft having an axial bore into which oil can be introduced via an oil supply system, at least one loose wheel which is rotatably supported on the shaft via a bearing, and a shift clutch arrangement which is arranged for connecting the loose wheel with the shaft in a rotationally fixed manner. The shift clutch arrangement comprises a guide sleeve which is connected with the shaft via a tooth engagement in a rotationally fixed manner. The axial bore is connected via at least one transversal bore with the outer circumference of the shaft, so as to supply oil to the bearing and to the shift clutch arrangement. The transversal bore is arranged in an area of the tooth engagement between the guide sleeve and the shaft. A channel is provided in at least one of an area of a toothing of the guide sleeve and an area of the toothing of the shaft, which, together with the guide sleeve toothing, forms the tooth engagement. The channel connects the transversal bore with an area between the guide sleeve and the bearing. | 09-23-2010 |
20120316023 | MOTOR VEHICLE DRIVE TRAIN - Drive train for a motor vehicle, having an electric machine for providing motive power, and a transmission arrangement. The transmission arrangement has a transmission input shaft and a first and a second gear stage. The transmission input shaft is connected to the electric machine. The drive train has a differential, which is connected to an output of the transmission and is set up to distribute motive power to two drive shafts.

A pressure pad arrangement absorbs axial forces arising from the helical toothing. | 12-13-2012 |
20130056322 | CLUTCH ARRANGEMENT, MOTOR VEHICLE DRIVE TRAIN AND CLUTCH ACTIVATION METHOD - A clutch arrangement for connecting two components, which can rotate relative to one another, of a motor vehicle drive train, in particular for connecting two shafts of a transmission or a shaft to an idler gear rotatably mounted on the shaft. The clutch arrangement has a clutch and an actuator arrangement. The clutch is opened in a first actuator position of an actuator section of the actuator arrangement. The clutch arrangement has a locking device for locking the actuator section in a locked position to keep the clutch closed. The locking device has a slotted-link guide with a first guide section and a second guide section for the actuator section, wherein the locked position can be reached from the first actuator position via the first guide section, and wherein the first actuator position can be reached from the locked position via the second guide section. | 03-07-2013 |
20130059668 | SHAFT ARRANGEMENT FOR A TRANSMISSION - A shaft arrangement for a transmission comprises a shaft having an axial bore connected to an oil supply system, at least one loose wheel rotatably supported on the shaft via a bearing, and a shift clutch arrangement which connects the loose wheel for rotation with the shaft. The shift clutch arrangement comprises a guide sleeve connected for rotation with the shaft via a tooth engagement. The axial bore supplies oil to the bearing and shift clutch arrangement via a transversal bore in an area of the tooth engagement between the guide sleeve and the shaft. A channel in at least one of an area of a toothing of the guide sleeve and an area of the toothing of the shaft, which, together with the guide sleeve toothing, forms the tooth engagement connects the transversal bore with an area between the guide sleeve and the bearing. | 03-07-2013 |

20130192948 | DRIVETRAIN-CLUTCH ARRANGEMENT AND FLUID CYLINDER THEREFOR - Fluid cylinder for activating an element of a drivetrain of a motor vehicle. The fluid cylinder has a cylinder housing and a piston. The piston is sealed off from the cylinder housing by means of a piston seal. At least one fluid chamber is formed between the cylinder housing and the piston, which fluid chamber can be connected via at least a first fluid connection to a fluid supply device. The piston in a piston stop position rests against a stop surface of the cylinder housing. The first fluid connection is formed in the region of the stop surface of the cylinder housing. The piston is connected to a sealing device which seals off the first fluid connection in the piston stop position. | 08-01-2013 |
20130305861 | CLUTCH ARRANGEMENT AND TWO-SPEED GEARBOX - Clutch arrangement for a motor vehicle gearbox. The clutch arrangement has a housing and a clutch. The clutch is arranged in the housing and is arranged concentrically with a shaft, which extends in a longitudinal axis. The shaft is supported on the housing by means of a first shaft bearing adjacent to the clutch and by means of a second shaft bearing spaced at an axial distance from the clutch. The clutch arrangement has an actuator arrangement for actuating the clutch. The actuator arrangement is designed to exert an actuating force on the clutch in a first longitudinal direction. The actuator arrangement here being axially braced on the housing and a force flux being introduced into the shaft as a result of the actuating force. The first shaft bearing is arranged so that the force flux introduced into the shaft can be axially braced on the housing by way of the first shaft bearing. | 11-21-2013 |
20130306431 | ACTUATOR ARRANGEMENT FOR A MOTOR VEHICLE DRIVE TRAIN - Actuator arrangement for a drive train, which has at least one friction clutch for transmitting drive torque and has a transmission. The friction clutch can be actuated by means of a hydraulic clutch cylinder, which is connected directly to a pump port of a pump driven by an electric motor in order to actuate the friction clutch, such that the friction clutch can be actuated by varying the speed of the pump. The actuator arrangement has a parking lock actuator device for actuating a parking lock arrangement of the drive train. The parking lock actuator device has at least one hydraulic parking lock cylinder, which can be connected to the pump, such that the parking lock arrangement can be actuated by varying at least one of the direction of rotation or the speed of the pump. | 11-21-2013 |
20140033844 | STEP-VARIABLE TRANSMISSION FOR A MOTOR VEHICLE - Step-variable transmission for a motor vehicle. The transmission has a gearbox inlet, which can be connected to a drive motor, and has a gearbox outlet, which can be connected to a driven axle of the motor vehicle. The step-variable transmission is designed for establishing at least a first gear and a further gear.
