Abstract: A baseboard apparatus for an electrical installation. The baseboard apparatus includes a rail device attachable to a wall structure and connectable to a power supply network using longitudinal contact bars. A placement device is attachable to the rail device using socket units and frame units. The socket units are contactable by the contact bars at various longitudinal positions on the rail device. The frame units can be mounted on the rail device in order to cover the rail device outside the socket units. The rail device includes a data transmission bar connectable to a data network. The placement device includes data transfer interfaces, which are contactable at various longitudinal positions of the rail device by the data transfer bar.

Abstract: An axial bearing arrangement with a first and second bearing rings that are rotatable relative to each other. First rolling bodies are arranged axially between the rings for supporting the rotation of the two bearing rings. The rolling bodies are arranged running on raceways of the first bearing ring and of the second bearing ring during rotation. At least one third bearing ring is arranged offset axially with respect to the second bearing ring, and therefore the second bearing ring is arranged so as to be rotatable relative to the third bearing ring. Second rolling bodies are arranged axially between the second bearing ring and the third bearing ring for supporting the rotation of the second bearing ring relative to the third bearing ring. The second rolling bodies are arranged running on raceways of the second bearing ring and of the third bearing ring during rotation.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a multistage transmission for an internal combustion engine with a disconnect-type clutch, a drive shaft and a driven shift on which engaged gear wheels are arranged to achieve different gear steps. Clutches (S1 to S4) actuated via shift forks (6 to 12) are used to move the speed gears to generate a frictional connection with the gear shaft (2, 4). The gear change is effected by means of a control cable and/or gearshift linkage. It is proposed that the gear pairs for the even gears (G2, G4, G6) and for the odd gears (G1, G3, G5, G7) are arranged side by side in the manner of a dual clutch gear set. To implement an H shift pattern to actuate the clutches (S1 to S4) of the even gears (G2, G4, G6) and the odd gears (G1, G3, G5, G7) a shifter shaft (14, 16) is provided, respectively. The two shifter shafts can be controlled via a common selector and/or shift control system.
