Abstract
A device for switching at least two partial gear mechanisms, namely a first partial gear mechanism and a second partial gear mechanism, each having at least two gear stages. The device comprising an actuator connected for drive purposes to a rotatable component, a first switching device for switching the first partial gear mechanism and a second switching device for switching the second partial gear mechanism both of which are arranged on the rotatable component, and an electric drive axle for a motor vehicle comprising a first drive wheel, a second drive wheel and such a device.
Claims13
An electric drive axle for a motor vehicle, comprising:
- a first drive wheel;
- a second drive wheel;
- a first partial gear mechanism assigned to the first drive wheel and having at least two gear stages;
- a second partial gear mechanism assigned to the second drive wheel and having at least two gear stages;
- and
- a device configured to switch the first partial gear mechanism and the second partial gear mechanism, the device including an actuator connected for drive purposes to a rotatable component, a first switching device arranged on the rotatable component configured to switch the first partial gear mechanism between its two gear stages, and a second switching device arranged on the rotatable component configured to switch the second partial gear mechanism between its two gear stages, wherein the first switching device and the second switching device each comprise:
- a sleeve arranged rotationally fixedly but axially moveable on the rotatable component,
- a shift gate formed on the sleeve,
- a guide element arranged fixedly relative to the device and engaging in the shift gate,
- a shift fork arranged axially moveable on the sleeve and engaging in a sliding collar of the respective partial gear mechanism, and
- an elastic storage arrangement which can be loaded by the sleeve via a first carrier element arranged fixedly on the sleeve in order to transmit a load to the shift fork.

An electric drive axle for a motor vehicle, comprising:
- a first drive wheel;
- a second drive wheel;
- a first partial gear mechanism assigned to the first drive wheel and having at least two gear stages;
- a second partial gear mechanism assigned to the second drive wheel and having at least two gear stages;
- and
- a device configured to switch the first partial gear mechanism and the second partial gear mechanism, the device including an actuator connected for drive purposes to a rotatable component, a first switching device arranged on the rotatable component configured to switch the first partial gear mechanism between its two gear stages, and a second switching device arranged on the rotatable component configured to switch the second partial gear mechanism between its two gear stages, wherein the first switching device and the second switching device each comprise:
- a sleeve arranged rotationally fixedly but axially moveable on the rotatable component,
- a shift gate formed on the sleeve,
- a guide element arranged fixedly relative to the device and engaging in the shift gate,
- a shift fork arranged axially moveable on the sleeve and engaging in a sliding collar of the respective partial gear mechanism, and
