摘要:
Parking lock arrangement, having a parking lock mechanism, which can be moved between a parking lock position and a release position, and having an operating device which is supported so that it can rotate about a first axis and which is designed, through rotation, to operate the parking lock mechanism. The parking lock arrangement further has an actuating mechanism and a coupling device which couples the operating device to the actuating mechanism. The actuating mechanism is supported so that it can rotate about a second axis relative to a drum, which is rotatable about the second axis via a drive.

Dual coupling gear mechanism for a motor vehicle, having a first input shaft and a second input shaft and having a first and a second countershaft, the input shafts and the countershafts being connected to each other by means of a plurality of shiftable wheel sets in order to establish at least seven forward gear stages and at least one reverse gear stage. At least one wheel set has a fixed wheel which is connected to one of the input shafts and two loose wheels which are rotatably supported on the first and on the second countershaft, respectively, and which are in engagement with the fixed wheel. An electric engine is connected to a loose wheel of one of the wheel sets or can be connected thereto by means of a shift clutch.

A hybrid drivetrain for a motor vehicle has an internal combustion engine, an electric machine, and a transmission arrangement for setting at least two different gears. The internal combustion engine and the electric machine are coupled to an input element of the transmission arrangement. A differential is coupled to an output of the transmission arrangement and is adapted to distribute motive power to two drive shafts. The electric machine and the internal combustion engine are coupled to a transmission input shaft of the transmission arrangement by way of a spur gear train.

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. Power in the first gear is transmitted from the gearbox inlet to the gearbox outlet by way of a first clutch arrangement. Power in the further gear is transmitted from the gearbox inlet to the gearbox outlet by way of a second clutch arrangement. The second clutch arrangement comprises a powershift clutch. The first clutch arrangement comprises an overrunning clutch.
摘要:
A shaft arrangement having a shaft and at least one component, which is arranged on the shaft and which is to be lubricated and/or cooled by a fluid. A fluid feed device being designed to feed the fluid to the shaft arrangement radially from outside. The component is a shaft sealing ring, which rests on the shaft and which is fixed to a housing. A baffle plate, which with the shaft sealing ring defines a fluid baffle chamber and which is separated by an annular gap from the outer circumference of the shaft, is arranged axially next to the shaft sealing ring. The fluid feed device is arranged so that fluid is fed into the fluid baffle chamber.
摘要:
A method for operating a hybrid drivetrain for a motor vehicle. Power is provided by an internal combustion engine in a first operating mode. Power is provided by an electric machine in a second operating mode. A change from one operating mode into the other operating mode is carried out according to the state of at least one of the drivetrain and the motor vehicle. The change of operating mode is controlled according to at least one switching variable, which is a function of a requested power target value.
摘要:
A system and method for maintaining the operation of an automated transmission (16), particularly a dual dutch transmission, for a motor vehicle, in case of a failure of an engine speed sensor (50) or a bus connection (44) between a first control module (42) controlling an engine (28) being connectable to the transmission (16) through at least one separation clutch (12, 149), and a second control module (34) controlling regulating units (12, 14) for connecting the engine (28) to the transmission (16) or to one or more driving wheels (34) in a force-transmitting manner, wherein gear-shift relevant data, particularly a number of revolutions (no) of the engine, is exchanged between the control modules (34, 42) over the bus connection (44).
摘要:
A parking lock arrangement for a motor vehicle gearbox. A parking lock cog can be fixed to a shaft of the motor vehicle gearbox rotatable about a first axis. A parking lock pawl is supported so that it can pivot about a second axis. An actuating mechanism can pivot the parking lock pawl into a locking position, in which the parking lock pawl meshes with the parking lock cog. A release mechanism can pivot the parking lock pawl out of the locking position into a release position, in which the parking lock pawl is decoupled from the parking lock cog. The actuating mechanism has a cam, which is supported so that it can pivot about a third axis and which in a first cam position holds the parking lock pawl in the locking position.

A shift arrangement for a motor vehicle transmission has a multiplicity of gear stages. The shift arrangement has a shift shaft which is aligned in an axial direction and has a multiplicity of shift members which are designed to engage on shift sleeves which can be displaced axially in order to shift the gear stages. The shift shaft is mounted so as to be rotatable in order to select in each case one of the shift sleeves and so as to be axially displaceable in order to shift the gear stages. The shift members have in each case one driver device for coupling to the shift shaft. The shift shaft has a coupling arrangement which is designed to engage, depending on the rotational position of the shift shaft, in each case with a driver device of one of the shift members in order to couple that shift member axially to the shift shaft. The driver devices have in each case a multiplicity of at least three lugs which are aligned in the axial direction and which make it possible for the associated shift member and the shift shaft to be coupled to one another in a multiplicity of axial relative positions.
