A securing device for securing a stationary state of an electric vehicle includes a gearshift interlock device and a differential interlock device. The gearshift interlock device has a gearshift interlock drive with a gearshift interlock shaft for driving a gearshift interlock between a gearshift interlock position and a gearshift release position. The differential interlock device has a differential interlock drive with a differential interlock shaft for driving a differential interlock between a differential interlock position and a differential release position. The gearshift interlock shaft and the differential interlock shaft are connected to one another in a drive-transmitting fashion.

Securing device for securing a stationary state of an electric vehicle

A securing device for securing an electric vehicle in a stationary position. The securing device having a transmission locking device and an axle locking device. The transmission locking device has a transmission locking drive with a transmission locking shaft for driving a transmission lock between a transmission locking position and a transmission release position. The axle locking device has an axle locking drive with an axle locking shaft for driving an axle lock between an axle locking position and an axle release position. The transmission locking shaft and the axle locking shaft are formed independently of one another.

Securing device for securing a standstill of an electric vehicle

A motor vehicle transmission for coupling an electric machine to a drivetrain of an electrically driveable motor vehicle. The motor vehicle transmission includes a planetary transmission for converting a torque that is introducible by the electric machine. An internal gear of the planetary transmission has an input toothed gear for forming a spur gear stage with a drive shaft of the electric machine. A brake immobilizes a sun gear of the planetary transmission with a static housing. A clutch rotationally conjointly connects the sun gear to the internal gear. The brake and the clutch at least partially overlap as viewed in a radial or axial direction. By virtue of the overlap, it is possible for axial and radial structural space, respectively, to be saved, such that a motor vehicle transmission with a small structural space requirement is made possible.

Motor vehicle transmission

An electric axle drive has a transmission arrangement with two gears, with an electric machine for driving two output shafts of the axle of the motor vehicle, a first spur gear stage which can be driven by the electric machine for driving an intermediate shaft and a planetary carrier of a planetary gear mechanism, which planetary carrier is connected fixedly to the intermediate shaft and receives planetary gears, and with an internal gear of the planetary gear mechanism for driving a second spur gear stage, a sun gear of the planetary gear mechanism and shifting elements for shifting the two gears. A first shifting element is configured as a clutch, by way of which the internal gear and the sun gear or the internal gear and the planetary carrier or the sun gear and the planetary carrier can be connected in a torque-transmitting manner.
