Transmission device for an electrically driveable vehicle, drive device for an electrically driveable vehicle, and vehicle
View Patent ↗Described is a transmission device ( 1 ) for an electrically driveable vehicle having a transmission element ( 2 ), a parking lock ( 6 ), by which the transmission element ( 2 ) can be blocked and which has a parking lock actuator ( 8 ), and a transmission housing ( 9 ), which encloses the transmission element ( 2 ) and the parking lock ( 6 ). A pressure equalization apparatus ( 14 ) is connected to an exterior of the transmission housing ( 9 ) in a gas-permeable manner. The pressure equalization apparatus ( 14 ) has a lead-through element ( 16 ) which passes through a transmission housing opening ( 15 ) and a fluid guiding element ( 17 ), the first end of which is connected to the interior of the parking lock actuator ( 8 ) and the second end of which is connected to the lead-through element ( 16 ).
1. A transmission device for an electrically driveable vehicle, comprising:
a transmission element;
a parking lock by which the transmission element is blocked and which has a parking lock actuator;
a transmission housing that encloses the transmission element and the parking lock; and
a pressure equalization apparatus by which an interior of the parking lock actuator is connected to an exterior of the transmission housing in a gas-permeable manner,
wherein the pressure equalization apparatus comprises a lead-through element which passes through a transmission housing opening, and a fluid guiding element, the first end of which is connected to the interior of the parking lock actuator and the second end of which is connected to the lead-through element.
2. The transmission device as claimed in claim 1 , wherein the pressure equalization apparatus at the first end of the fluid guiding element has a first coupling which is connected in a latching manner to a diametrically opposed second coupling of the parking lock actuator, and wherein the second end of the fluid guiding element has a third coupling which is connected in a latching manner to a diametrically opposed fourth coupling of the lead-through element.
3. The transmission device as claimed in claim 2 , wherein the first coupling at the first end of the fluid guiding element is configured as a cup coupling and/or the third coupling at the second end of the fluid guiding element is configured as a cup coupling.
4. The transmission device as claimed in claim 2 , wherein the second coupling of the parking lock actuator and/or the fourth coupling of the lead-through element has or have a latching collar.
5. The transmission device as claimed in claim 1 , wherein the lead-through element has a membrane outside the transmission housing.
6. The transmission device as claimed in claim 1 , wherein the lead-through element has a gas-permeable protective cap at its free end outside the transmission housing.
7. The transmission device as claimed in claim 1 , wherein the lead-through element has at least one sealing means which seals the lead-through element in relation to the transmission housing opening.
8. The transmission device as claimed in claim 7 , wherein the sealing means comprises one or more sealing rings.
9. The transmission device as claimed in claim 1 , wherein the lead-through element is fastened by means of a press fit in the transmission housing opening or is passed through the transmission housing opening with a plug connector.
10. A drive device for an electrically driveable vehicle, comprising:
an electric machine;
a transmission device as claimed in claim 1 ; 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. A vehicle, comprising: a drive device as claimed in claim 10 , which is configured for driving the vehicle.
