A connection assembly () between two housing chambers () of a control unit, includes a housing having at least two housing chambers () and a housing partition wall () for separating the two housing chambers () and defines a break-through (). The first housing chamber () is configured as a dry chamber and comprises at least one first contact partner. The second housing chamber () is configured as a wet chamber and comprises at least one second contact partner. An electrical line () electrically connects at least the first contact partner to the second contact partner. The electrical line () is guided through the break-through () and includes, locally in the region of the break-through (), a single-layer or multi-layer sheathing () for sealing the break-through (). An electronics module utilizing the connection assembly is also disclosed.

A seal device () for a rotating shaft (). The seal device has a shaft seal () and a collecting device () for the contactless removal of leakage, that penetrates through the shaft seal (), from the shaft (). Further, an electric machine has a rotor shaft () that can be driven in rotation and a seal device () of the type for sealing the rotor shaft () and, therefore, also an inside space of the electric machine. Additionally, a drive device for the electrical driving of a motor vehicle that has an electric machine of the type for the provision of a drive power of the drive device.

Seal device, electric machine, and drive device

A seal device () for a rotating shaft (). The seal device has a shaft seal (), a shaft grounding connection () and a holding feature () for holding the shaft seal () and the shaft grounding connection (). The holding feature () has at least one opening (), between the shaft seal () and the shaft grounding connection (), for clearing particles away from the shaft seal () and the shaft grounding connection (). An electric machine with a rotor shaft () that can be driven in rotation and with a seal device () of the above type for sealing the rotor shaft () and, therefore, also sealing an inside space of the electric machine. Furthermore, a drive unit for electrically driving a motor vehicle, including an electric machine of the above type for providing drive power of the drive unit.

An electric drive unit with an electric machine arranged in a motor housing. The electric machine has a rotor and a stator. A transmission is arranged in a transmission housing and driven by the electric machine. A cooling sleeve is provided, which forms a radially outward facing hollow space for a coolant by virtue of a spiral-shaped circumferential web between itself and the surrounding motor housing. Furthermore the cooling sleeve has a holding web which is designed to be clamped between two motor housing components.

A transmission system for either a manual shift transmission, an automatic transmission or an automated transmission in which the electrical connections and the pneumatic connections including any ventilation port, for the internal components of the transmission are combined with one another so as to exit the transmission housing via a single unified connection formed in the housing wall of the transmission.

Transmission system

A transmission () having a transmission housing () having a region in which gear wheels () rotate and a heat exchanger () which absorbs the heat generated in the transmission (). This heat is transferred to a transmission lubricant and released to a coolant to transport the heat away from the transmission (). A recess () is provided, in the transmission housing () outside of the region in which the gearwheels () rotate, through which transmission lubricant flows and in which the heat exchanger () is arranged. The heat exchanger () has a bypass valve () which enables the heat exchanger () to be bypassed starting at a predefined low or excess pressure.

A shift rocker arrangement for a transmission including a two-arm bracket shift rocker that extends around a transmission element to be shifted and is supported by pivot bearings on the arms of the bracket within a transmission housing to pivot about an axis located essentially in the plane of the bracket. The shift rocker has bearing elements formed on the bracket arms and complementary bearing shells are formed on the inside wall of the closed housing. The bearing shells that support the bearing elements of the shift rocker are either formed on a bearing bar, which is supported at both ends by the housing, or they are formed directly on inside walls of the housing.

An arrangement of the intermediate gear for a reverse gear () is proposed for a transmission with a drive shaft and an output shaft () arranged coaxially in relation to it and with one additional intermediate shaft () arranged parallel to the drive and output shafts () for a power take-off. The intermediate gear for the reverse gear () is driven by a shaft () and drives the output shaft (), in which the intermediate gear for the reverse gear () is arranged above an imaginary plane (A) extended through the axes of the driving shaft () and the output shaft () and, with a horizontal orientation of plane (A), the driving shaft () is located to the right of the output shaft () in the direction of travel.
