A device () to drive at least an output shaft () of a rail vehicle with a drive engine (). The at least one output shaft () can be brought into an operational connection with a wheel (), and a transmission assembly () is positioned on the drive side of the at least one output shaft (). At least two gear ratios can be presented in the area of the transmission assembly (). In addition, a method is described for operating such a device ().

Device for driving at least one output shaft of a rail vehicle and method for operating such a device

A gear train with at least first and second spur gears () which have a tooth width (b), mesh with one another and each have helical teeth (). The first spur gear () has a tooth profile with a crown circle diameter and the second spur gear () has a tooth profile with a root circle diameter. The first spur gear () has at least one projection () on the tooth profile that extends partially along the tooth width and beyond the crown circle diameter, and the at least one projection () has at least one contact face () in the axial direction.

Gear mechanism having helical toothing

A transmission () for a motor vehicle () with a housing () and a shifting apparatus arranged therein and with an electromechanical transmission actuator () with a first electric motor () for exercising a selection motion of the shifting device with a second electric motor () for exercising a shifting motion of the shifting apparatus and with a control unit () for receiving sensor signals, for processing the sensor signals and for emitting control signals to the electric motors () the axis of rotation of the first electric motor () and the axis of rotation of the second electric motor () lie parallel to each other.
