An arrangement for actuating a shift element of a gearbox includes a rotatably mounted and preloaded shift pawl () and a shift ring () with an outer toothing () and assigned to a gearbox element. A first end () of the shift pawl () is assigned to the outer toothing () of the shift ring () so as to lock or release the shift ring () in order to shift a gear stage, and a second end () of the shift pawl () is assigned to a shift gate () of a shift drum () that actuates the shift pawl (). The shift pawl () is operatively connected to at least one double torsion spring () in order to apply a preload force.

Assembly for actuating a shifting element of a transmission

An arrangement for actuating a shift element for a bottom bracket gearbox () includes a shift ring () rotatably mounted in a housing () and assigned to a gearbox component. A shift pawl () for locking or releasing the shift ring () is assigned to the shift ring () for shifting a gear stage. A support region mechanically reinforces the housing () and is provided at least along a contact region () between an inner wall () of the housing () and an outer circumference of the shift ring (). The contact region () is defined by reaction forces () acting when the shift ring () is locked.

A vehicle transmission includes a transmission housing defining an oil sump space and a hybrid space, with the hybrid space being arranged vertically above the oil sump space. The transmission further includes a first oil guide shell and a second oil guide shell each fixed to the transmission housing. Additionally, the transmission includes rotating components installable in a portion of the hybrid space between the first oil guide shell and the second oil guide shell in an axial direction, where the rotating components includes at least one electric machine, a damper, and a torsional shock absorber. Two contactless gap seals are formed by one of the oil guide shells and at least one of the rotating components such that oil entry from the oil sump into the portion of the hybrid space is delimited axially by the oil guide shells and radially by the gap seals.

A lubricant guide shell () for includes a first, radially extending section (), which is provided for being situated axially opposite an end face () of a torque converter () in an installed state of the lubricant guide shell (). The first section () transitions radially outwardly into a second, axially extending section (), which, in the installed state of the lubricant guide shell (), is configured for axially at least partially and radially outwardly encompassing the torque converter starting from the first section (). The first section () as well as the second section () are configured to be completely circumferential.

A piping () for guiding a fluid within a drive train unit (G) of a motor vehicle includes a pipe (R). A stop (RA) is formed at a first end (R) of the piping (). A sealing element (RD) is provided at a second end (R) of the piping (). The sealing element (RD) acts as an axial seal. In order to improve a sealing effect of the sealing element (RD), the piping () is loaded along an extension direction of the piping (). A drive train unit (G) for a motor vehicle including such a piping () and a method for installing such a piping () into such a drive train unit (G) is also provided.

Piping, drive train unit comprising such a piping, and installation method

A hybrid drive unit (HY, G) for a motor vehicle includes a housing (GG), in which a torque converter (TC) and an electric machine (EM) are accommodated. The electric machine (EM) and the torque converter (TC) are arranged directly next to each other such that the electric machine (EM) is arranged at a first face end (TC) of the torque converter housing (TCG). An oil guide shell (LS) at least partially encompasses a section of the torque converter (TC). The oil guide shell (LS) has an L-shaped cross-section including a first section (LS) and a second section (LS) and is arranged in such that the first section (LS) partially encompasses a second face end (TC) of the torque converter housing (TCG) and the second section (LS) partially encompasses a circumferential surface of the torque converter housing (TCG).

Hybrid drive unit and drive train for a motor vehicle

A transmission has an input shaft, an output shaft coaxial to the input shaft, an intermediate shaft, a differential gear, and only one electric machine for driving a hybrid vehicle. The rotational axes of the input shaft, the intermediate shaft, the differential gear, and a rotor of the electric machine are axially parallel. The differential gear includes torque-transmitting interfaces to drive shafts connected to driving wheels of the hybrid vehicle. Torque is transmitted between the output shaft and the differential gear via the intermediate shaft. The rotor is permanently connected, via a constant gear ratio, to either the input shaft or a further shaft of the transmission. The rotational axis of the intermediate shaft is arranged spatially below a connection line between the rotational axes of the input shaft and the differential gear, and the rotational axis of the rotor is arranged spatially above the connection line.

Disclosed is a training evaluation device for a vehicle having a first input interface for receiving a recording of a sign given by a road user, and a second input interface for receiving a driver control command corresponding to the sign, wherein the training evaluation device propagates an artificial neural network with the recording of the sign and the driver control command to obtain a vehicle control command in the propagation of the artificial neural network, and adjusts weighting factors such that the vehicle control command matches the driver control command, for the machine learning of a meaning of the sign. A method for training an artificial neural network, a working evaluation device for an automatically operated vehicle, a driver assistance system, and a method for recognizing a meaning of a sign and for indicating a vehicle reaction to a known meaning of this sign are also disclosed.
