DRIVE SYSTEM WITH VENTILATION
A drive system, in particular a drive system of a wheel hub, for a motor vehicle, in particular an electric and/or hybrid motor vehicle, the drive system including an electric motor. In order to prevent moisture from accumulating in an internal chamber ( 1 ) of the drive system, the drive system includes a ventilation device ( 20 ) for aerating and de-aerating the interior chamber ( 1 ) of the drive system. The ventilation device ( 20 ) includes at least one air supply device ( 21 ) for supplying air into the internal chamber ( 1 ) of the drive system and at least one air removal device ( 22 ) for removing air from the internal chamber ( 1 ) of the drive system.
1 - 10 . (canceled)
11 . A drive system for a vehicle, the drive system having at least one drive system internal chamber, the drive system comprising:
an electric motor having a stator and a rotor; and
a ventilation device for aerating and de-aerating the drive system internal chamber, the ventilation device including at least one air supply device for supplying air to the drive system internal chamber and at least one air removal device for removing air from the drive system internal chamber.
12 . The drive system as recited in claim 11 wherein the air supply device is situated above a drive axis of the drive system or the air removal device is situated below the drive axis.
13 . The drive system as recited in claim 11 wherein the air supply device include at least one filter or at least one dryer.
14 . The drive system as recited in claim 13 wherein the air supply device includes a particle filter or a moisture filter or a gas filter.
15 . The drive system as recited in claim 11 wherein the air supply device is designed as an active or temporarily active air supply device for at least temporarily actively supplying air to the drive system internal chamber.
16 . The drive system as recited in claim 15 wherein the air supply device is temporarily connectable or permanently connected to a ventilation system of the vehicle or is temporarily connectable to a maintenance ventilation system.
17 . The drive system as recited in claim 16 wherein the sir supply device is connected to an air conditioning system of the vehicle.
18 . The drive system as recited in claim 11 wherein air from a vehicle interior, is suppliable to the drive system internal chamber with the aid of the air supply device.
19 . The drive system as recited in claim 18 wherein the air is from a passenger cell or a storage compartment.
20 . The drive system as recited in claim 19 wherein the air is from a trunk.
21 . The drive system as recited in claim 11 wherein the air supply device is situated on a stationary drive system element of the drive system.
22 . The drive system as recited in claim 21 wherein the stationary drive system element of the drive system is fixedly connected to the stator of the electric motor.
23 . The drive system as recited in claim 22 wherein the air supply device is on a stator retaining plate.
24 . The drive system as recited in claim 11 wherein the air supply device includes an air supply connecting element for the airtight connection of the air supply device to the drive system internal chamber, or the air removal device includes an air removal connecting element for the airtight connection of the air removal device to the drive system internal chamber.
25 . The drive system as recited in claim 11 wherein the air supply device includes a valve, or the air removal device includes a further valve.
26 . The drive system as recited in claim 25 wherein the air removal device includes a check valve.
27 . The drive system as recited in claim 25 wherein the air removal device includes the further valve, the further valve being designed to allow air to flow out of the drive system internal chamber and to prevent air from flowing into the drive system internal chamber.
28 . The drive system as recited in claim 25 wherein the air supply device includes a check valve.
29 . The drive system as recited in claim 25 wherein the air supply device has the valve, the valve allowing air to flow into the drive system internal chamber and to prevent air from flowing out of the drive system internal chamber.
30 . The drive system as recited in claim 11 further comprising a friction brake.
31 . The drive system as recited in claim 11 wherein drive system internal chamber surrounds a gap between the stator and the rotor of the electric motor or surrounds a friction brake.
