Abstract
A rear bridge comprises bridge legs, a motor shell, a motor shell cover, a stator iron core, an armature winding, a magnetic yoke, a differential assembly, a Hall element, a bearing and so on, a motor stator which consists of the armature winding and the stator iron core is fixed on the motor shell, a motor rotor which consists of the magnetic yoke and a permanent magnet is fixed on the differential assembly, and the Hall element which is fixed on the stator iron core can ensure the normal operation of the motor. The electric rear bridge has simple structure and reduced volume as the rotation of the motor is directly acted on the differential assembly of the rear bridge.
Description
Affiliated technical field
The utility model relates to a kind of by electrically driven (operated) electronic back axle, and it is that a kind of stator of motor is fixed on the axle housing, and rotor is fixed on the back axle on the differential mechanism.
Background technology
At present, known electrically driven (operated) electronic back axle, motor are outside axle housing, and the outputting power of motor passes to differential mechanism on the back axle by machine driving, and whole like this power and transmission mechanism complex structure, volume is too fat to move and huge.
Summary of the invention
For the whole power that overcomes existing electric driving rear axle and transmission mechanism complex structure, the too fat to move and huge deficiency of volume, the utility model provides a kind of electronic back axle, directly in axle housing, the stator of motor is fixed on the axle housing its motor, and rotor is fixed on the back axle on the differential mechanism.This electronic back axle is simple in structure, volume-diminished.
The technical scheme that its technical problem that solves the utility model adopts is: the stator of motor is fixed in the axle housing, and rotor is fixed on the outer back axle of differential assembly.Electronic back axle is simple in structure, volume-diminished.
The motor casing of back axle and motor cap are fixed on the bridge leg of both sides, and stator core is fixed on the motor casing, and on the armature winding fixed stator iron core, promptly the motor stator of being made up of armature winding, stator core is fixed on the motor casing.Yoke is fixed on the differential assembly skin, and permanent magnet is the yoke skin fixedly, and promptly the rotor of being made up of yoke, permanent magnet is fixed on the differential assembly.And the Hall element that is fixed on the stator core plays guarantee effect to the normal operation of motor.Because the rotation of motor acts directly on the differential assembly of back axle, makes this electronic back axle simple in structure, volume-diminished.
The beneficial effects of the utility model are, motor stator is fixed in the axle housing of back axle, rotor be fixed on differential mechanism total on.This electronic back axle is simple in structure, volume-diminished.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is a part sectioned view of the present utility model.
1. bearings among the figure, 2. motor cap, 3. screw, 4. differential assembly, 5. yoke, 6. permanent magnet, 7. stator core, 8. armature winding.9. motor casing, 10. Hall element, 11. bridge legs
Embodiment
In the drawings, the bridge leg (11) at back axle two ends is connected with motor casing (9) with motor cap (2) respectively by screw (3), stator core (7) is fixed on the motor casing (9), on armature winding (8) the fixed stator iron core (7), promptly by armature winding (8), the motor stator that stator core (7) is formed is fixed on the motor casing (9), yoke (5) is fixed on differential assembly (4) skin, permanent magnet (6) is fixed on yoke (5) skin, promptly by yoke (5), the rotor that permanent magnet (6) is formed is fixed on the differential mechanism total (4), and Hall element (10) is fixed on the stator core (7).Because the rotation of motor acts directly on the differential assembly of back axle, makes this electronic back axle simple in structure, volume-diminished.
Claims (1)
1. back axle of forming by bridge leg, motor casing, motor cap, stator core, armature winding, yoke, differential assembly, Hall element, bearing etc., it is characterized in that: motor stator is fixed on the rear axle housing body, rotor be fixed on differential mechanism total on.
