Transmission device for an electrically driveable vehicle, drive device for an electrically driveable vehicle, and vehicle
A transmission device for an electric vehicle that includes a transmission element, a parking lock with a parking lock actuator which blocks the transmission element, and a transmission housing which encloses the transmission element and the parking lock. The device further includes a first connection apparatus that has a first cable arrangement that extends into the transmission housing and a first plug connector by which the first cable arrangement connects the exterior of the transmission housing to the parking lock actuator. The device further includes a pressure equalization apparatus which runs through the first plug connector of the first connection apparatus and forms a gas-permeable connection between the interior of the parking lock actuator and the exterior of the transmission housing.
1. A transmission device for an electrically driveable vehicle, comprising:
a transmission element;
a parking lock, by which the transmission element is blocked and comprising a parking lock actuator;
a transmission housing, which encloses the transmission element and the parking lock;
a first connection apparatus with a first cable arrangement extending in the transmission housing and a first plug connector by which a first end of the first cable arrangement contacted from an exterior of the transmission housing, wherein a second end of the first cable arrangement is electrically connected to the parking lock actuator;
a pressure equalization apparatus, which runs through the first plug connector of the first connection apparatus and forms a gas-permeable connection between an interior of the parking lock actuator and the exterior of the transmission housing;
a second connection apparatus with a second cable arrangement; and
a third plug connector arranged at a first end of the second cable arrangement, by which an electrical plug connection is formed with the first plug connector of the first connection apparatus,
wherein the pressure equalization apparatus has a second fluid guiding element, wherein a first end of the second fluid guiding element extends into the third plug connector of the second connection apparatus.
2. The transmission device as claimed in claim 1 , wherein the pressure equalization apparatus has a first fluid guiding element which connects the first plug connector to the interior of the parking lock actuator.
3. The transmission device as claimed in claim 2 , wherein the first fluid guiding element is guided together with the first cable arrangement from the parking lock actuator to the first plug connector.
4. The transmission device as claimed in claim 2 , wherein the first plug connector has a plug connector housing, contact elements, and through openings which are formed in the plug connector housing and which are each designed to receive one of the contact elements, wherein the first fluid guiding element is inserted into one of the through openings.
5. The transmission device as claimed in claim 1 , wherein the second end of the first cable arrangement is electrically connected to the parking lock actuator by a second plug connector of the first connection apparatus and the pressure equalization apparatus extends into the second plug connector.
6. The transmission device as claimed in claim 1 , wherein the second connection apparatus has a fourth plug connector at a second end of the second cable arrangement.
7. The transmission device as claimed in claim 6 , wherein the pressure equalization apparatus has a pressure equalization adapter at a second end of the second fluid guiding element.
8. The transmission device as claimed in claim 7 , wherein the pressure equalization adapter and the fourth plug connector of the second connection apparatus are separate components.
9. The transmission device as claimed in claim 7 , wherein the pressure equalization adapter has a membrane and/or a fastening means for fastening the pressure equalization adapter.
10. A drive device for the electrically driveable vehicle, comprising:
an electric machine;
the transmission device as claimed in claim 9 ; and
a shaft transmitting a rotational motion of the electric machine to the transmission device.
11. The drive device as claimed in claim 10 , wherein the transmission housing is part of a housing enclosing the electric machine, the transmission device, and the shaft.
12. The drive device as claimed in claim 11 , wherein the pressure equalization adapter is fastened to the housing by the fastening means.
13. The drive device as claimed in claim 10 , further comprising:
an inverter, wherein the fourth plug connector of the second connection apparatus is electrically connected to the inverter.
14. A vehicle, comprising: the drive device as claimed in claim 10 , which is configured to drive the vehicle.
