A gearwheel () for a gear step in an electric vehicle transmission () includes a gearwheel carrier and a toothed ring () having an external toothing (). The toothed ring is rotationally fixable to the gearwheel carrier. The gearwheel carrier is formed by a first partial carrier () and a second partial carrier () that are at least partially axially spaced apart and extend from the toothed ring radially inward. An axial spacing of the two partial carriers is greater, at least partially, than an axial length of the toothed ring.

Gearwheel for an electric vehicle transmission

A drive unit for an electrically driven vehicle with an inverter module, an electric machine a stator which is controllable by the inverter module. The rotor of the electric machine rotationally drivingly communicates with at least one shaft of the drive unit, the shaft being rotatably supported in a respective associated housing by a bearing arrangement. The housing and the inverter module are grounded. Further, the drive unit has a grounded, low-impedance electrical connection between the shaft and the inverter module so that, when a potential difference occurs between the shaft and the inverter module, a short circuit is produced. Low-impedance potential equalizer is provided between the shaft and the associated housing. It is provided that the shaft is formed as a rotor shaft or as a transmission shaft, the bearing arrangement has two bearings spaced apart axially from one another, and the potential equalizer is formed axially between the two bearings.

Drive unit for an electrically driven vehicle

A transmission for a bicycle includes at least four shift elements, one input shaft (), a first planetary gear set (PS) which is operatively connected to the input shaft (), and a second planetary gear set (PS). A carrier of the first planetary gear set is rotationally fixed to a carrier of the second planetary gear set (PS).

Transmission for a bicycle

A triple clutch arrangement and a powertrain for a motor vehicle with a dual clutch transmission for use between at least two drive devices and the dual clutch transmission. A first clutch and a second clutch of the triple clutch arrangement are connectable to the first drive device and in each instance to a transmission input shaft. The first drive device and the second drive device are both connected to, or connectable to, a primary side of the first clutch and/or the second clutch via the third clutch.

Triple clutch assembly, powertrain, and motor vehicle

A transmission for a bicycle includes an input shaft () which is rotationally fixable to a crankshaft (), and an output shaft () which is rotationally fixable to an output gear. The transmission includes at least three planetary transmissions which are operatively connected to the input shaft and to the output shaft. A single one of the planetary transmissions includes a stepped planetary gear () with a first gear teeth section () having a first diameter and a second gear teeth section () having a second diameter.
