Description
Technical field
That the utility model relates to is that car, accommodation move be used to ordering about, drive the electric energy drive system of the wheel hub that is used for connecting tire or blade; In particular for the electric wheel system on elec. vehicle, particularly for axle load heavy large-scale public transport manned vehicle, train, and the electric wheel system of high-performance electric motor-car.
Background technology
In recent years, use the electric vehicle development of the good wheel hub motor of mechanical efficiency very active.The prior art wheel hub motor is directly to bear car weight, road shocks load with the torque output shaft of motor, is not suitable for self car weight heavier, bears the stronger full size vehicle of impact load.Prior art also rests on the exploitation of elec. vehicle and improves the electrical efficiency aspect, comparatively slow for the research and development of supporting car weight, bearing the basic mechanical characteristicss such as road shocks load, also do not launch the research of countermeasure realistic applying working condition and that reduce costs aspect.
The prior art wheel hub motor is the direct axle shaft rotation of rotor, and wheel hub is installed on rotor, and axletree is not only born rotor weight, tire wheel hub weight, also bears the impact load on the road surface in driving process.For flexural load, the impact load of slowing down axletree and transmit moment of rotation and can run into following problem:
1. axletree need to use high strength material, causes cost to raise;
2. in order to ensure axletree intensity, can the axletree design is thicker, but bring simultaneously weight to increase, rideability decline problem;
3. when travelling, impact load is directly passed to the rotor of drive motor, causes the rotor fine motion, thereby rotor and stator gap can not be very little, and motor output can not improve; In order to control rotor fine motion and distortion, need to improve the intensity of each part simultaneously, cause manufacturing cost and tare to increase;
4. in order to improve bending strength under the equivalent weight condition, will strengthen the axletree diameter, and axletree can be made tubulose according to mechanics general knowledge, but the motor internal diameter is limited, order strengthens the axletree diameter and is difficult to realize;
5. disc brake device or drum type braking device are installed in wheel hub, and the weight of brake gear increases the burden of axletree, causes manufacturing cost and tare to increase;
6. vehicle maximizes, maximizes by brake and improve vehicle braking force, raising Vehicle Driving Cycle when the performance of uneven road surface, all makes Design freedom narrow because axletree intensity limits, and the prospect of electronlmobil is limited;
7. for improving motor output, can improve rotor diameter, because the wheel hub internal diameter is limited, motor output raising degree is little; And if add big hub, axletree is also wanted overstriking, causes car weight to increase, and rideability descends; Can not make the minitype high-performance battery-driven car that accords with the demands of the market;
8. for controlling the axletree distortion, improve axletree intensity, make axletree there is no elastic deformation, axle support directly is subject to impact load, thereby will improve axletree intensity, just causes manufacturing cost and tare to increase;
9. if increase axletree and circumferential component intensity thereof, causing recoil spring to bear weight increases, and rideability descends a lot, can only performance-oriented shock absorber, and cause manufacturing cost to improve;
10. above productive costs improves and causes selling price to rise, and greatly hinders battery-driven car universal, make the axletree circumferential component productive costs, assembling implementation, that performance is difficult to is the same with fuel vehicle enterprise;
11. when more than causing weight to increase, direct image rate of fuel consumption rate, this is to saying it is fatal with the battery-driven car that improves energy use efficiency.
