A drive unit having a transmission, which has an input axis and an output axis, which are arranged parallel to one another and spaced apart. In a drive unit of this kind, provision is made for the transmission to be designed as a cartridge which forms a unit and is connected to a support element forming a component part of the drive unit. A drive unit embodied in this way allows quick and easy mounting of the transmission while allowing for the required transmission forces and transmission torques of the transmission. Moreover, the transmission can be embodied in a space-saving way.

Drive unit having a transmission

A hybrid drive for a motor vehicle includes an internal combustion engine and an electric motor, which, together with at least one auxiliary unit, are connected via a belt/chain drive. The internal combustion engine and the electric motor have respective drive elements with unidirectional freewheeling devices for the belt/chain drive, thus automatically achieving a predefined belt/chain speed.

Hybrid drive for a motor vehicle

A double clutch for a hybrid drive of a motor vehicle, has an input shaft that can be driven by an internal combustion engine, and an output shaft that is connected to a transmission. An intermediate shaft extends coaxially to the output shaft and can be driven by an electric motor. The input shaft and the intermediate shaft can be coupled together by a first clutch of the double clutch. The intermediate shaft and the output shaft can be coupled together by a second clutch of the double clutch.

Double clutch for a hybrid drive

A multistage transmission for an internal combustion engine has a disconnect-type clutch, a drive shaft and a driven shift on which engaged gear wheels are arranged to achieve different gear steps. Clutches actuated via shift forks are used to move the speed gears to generate a frictional connection with the gear shaft. The gear change is effected by a control cable and/or gearshift linkage. The gear pairs for the even gears and for the odd gears are arranged side-by-side like a dual clutch gear set. To implement an H shift pattern to actuate the clutches of the even gears and the odd gears a shifter shaft is provided, respectively. The two shifter shafts can be controlled via a common selector and/or shift control system.

Multi-step manual transmission for an internal combustion engine

A manual transmission for a motor vehicle with a front transverse drive, has a wheel set which consists of a transmission input shaft and at least two transmission output shafts, both engaged via a gearwheel with the spur wheel of an axle differential. A-rotationally fixed connection of the loose wheels and/or gearshift wheels provided on the two transmission output shafts with the coupling units assigned to them is provided by gearshift forks displaceably arranged on the shift axles and selectable and operable via at least one gearshift lever shaft. For bearing and/or accommodation of the gearshift axles and the gearshift lever shaft, a common bearing unit is provided. The bearing unit is arranged between the wheel set (transmission input shaft, transmission output shaft) and the central opening in the axial differential.
