Definitions
- Electric drives for mobile vehicles are used, for example, as exclusive drives or auxiliary drives for rear axles in passenger cars.
- DE 100 49 514 B4 discloses an electric drive for a rear axle of a passenger car, in which an electric drive motor via a spur gear drives a differential whose output drive the wheels of the vehicle.
- the present invention has for its object to provide an electric drive for a mobile vehicle, which is inexpensive and easy to assemble.
- the electric drive has an electric motor, which drives two outputs of the differential gear via a spur gear and a differential gear, via which, for example by means of plug shafts, the wheels of the vehicle are driven.
- the electric drive has a housing which encloses the differential, the spur gear and the electric motor.
- the housing consists of a central housing part, which on the one hand receives the electric motor and on the other hand substantially the spur gear and the differential gear.
- ceiling-shaped housing parts are attached, which close the middle housing part.
- the middle housing part has on the one hand a cylindrical shaped extension in which the engine is arranged, and on the other hand, a parallel to the cylindrical extension arranged extension, in which the spur gear and the differential gear are arranged.
- cooling channels are arranged in the middle housing part in order to cool the electric motor.
- main cooling channels are preferably arranged parallel to the axis of rotation of the drive shaft of the electric motor, wherein these are designed so that they fill the space between the round rotor of the electric motor and the square outer contour of the central housing surrounding the electric motor.
- connecting channels located at the two end faces of the central housing part perpendicular to the rotational axis of the drive shaft of the electric motor arranged connecting channels, each connecting two main cooling channels, and the be closed with a stopper after drilling.
- On one of the two end faces is the coolant supply, from which the coolant enters one of the four main cooling channels.
- the coolant passes through the middle housing part to the other end face, where it is passed through the connecting channel in another main cooling channel and flows through the central housing part back to the first end side, where it is deflected again.
- the coolant passes through the channels until it exits on the first end side from the return, which is arranged on the same side as the coolant supply.
- the central housing part has receptacles for power electronics for the electric motor. Furthermore, it is possible to arrange sealing elements between the electric motor and the spur gear, whereby the electric motor remains oil-free.
- the spur gear may consist of four spur gears, wherein a first spur gear rotatably connected to the motor shaft of the electric motor and is operatively connected to a second spur gear which is rotatably connected to a third spur gear and rotatably supported via an intermediate shaft, wherein the third spur gear with a fourth spur gear is in operative connection, which is rotatably connected to the differential gear.
- the fourth spur gear is connected via a material connection with a differential carrier of the differential gear.
- the motor shaft is integrally connected to the first spur gear, whereby the first spur gear and the motor shaft must be stored only over two bearings.
- the motor shaft is mounted on three bearings, wherein a bearing at one end of the motor shaft and a bearing point at the other end of the motor shaft and a bearing between the rotor of the motor and the first spur gear is arranged.
- Fig. 1 shows a section through the electric drive.
- Fig. 2 is a rear view of the electric drive and
- Fig. 3 is a front view of the electric drive.
- An electric motor 1 drives with its motor shaft 2 to a first spur gear 3.
- the first spur gear 3 is in operative connection with the second spur gear 4, which is non-rotatably connected via an intermediate shaft 5 with a third spur gear 6.
- the third spur gear 6 is in operative connection with the fourth spur gear 7, which is rotatably connected to a differential carrier 8 of the differential gear 9.
- Via a first output 10 and a second output 1 1 vehicle wheels can be driven.
- the housing of the electric drive consists of a central housing part 12, a decker-shaped housing part 13 and a further lid-shaped housing part 14.
- the decker-shaped housing part 13 is at one end of the central housing part 12 and the lid-shaped housing part 14 is arranged at the other end of the central housing part 12.
- the middle housing part 12 consists of a cylindrical extension 15, in which the engine 1 is arranged, and of a parallel to the cylindrical extension 15 arranged extension 16, in which the differential gear 9 is arranged.
- the motor shaft 2 is supported on the one hand via the bearing 17 in the lid-shaped housing part 13 and on the other hand via the bearings 18 and 19 in the middle housing part 12 and in the further lid-shaped housing part 14. If there is no parking lock wheel on the motor shaft 2, then the motor shaft 2 and the first spur gear 3 integrally connected to it can also be mounted only via the bearing 17 in the housing part and the bearing 18 in the housing part 12. The bearing 19 can thus be omitted.
- the intermediate shaft 5 is mounted on the one hand via the bearing 20 in the middle housing part 12 and the bearing 21 in the further ceiling-shaped housing part 14.
- the differential gear 9 is mounted on the bearings 22 and 23 in the middle housing part 12 and in the further ceiling-shaped housing part 14.
- the first spur gear is disposed in the axial direction along the motor shaft between the electric motor 1 and the fourth spur gear 7.
- the middle housing part 12 has in the region of the differential gear 9 a reinforcing web 24, which connects the extension 16 with the cylindrical extension 15.
- the further ceiling-shaped housing part 14 has in the region of the differential gear 9 reinforcing ribs 25 which extend radially about the axis of rotation of the second output 1 1.
