Description
Technical field
The utility model relates to a kind of integrated electric wheel construction that is applied to the four-wheel drive fuel cell car, especially a kind of in limited wheel rim space, integrated motor and planetary gear reducing mechanism and brake are the planet carrier output type internal rotor integrated electric wheel of the integrated outside disk brake of one.
Background technology
The electric automobile of wheel hub electric motor driving at present mainly contains two types.A kind of is the motor that adopts the high speed internal rotor, and the epicyclic reduction gear unit that installs high speed reducing ratio between motor output shaft and wheel again additional reduces vehicle wheel rotational speed; Another kind then is to adopt the low speed outer rotor motor, and this kind motor need not any speed change gear and is directly installed on the rim for automobile wheel.The high speed inner rotor motor has that volume is little, light weight, cost is low and power density is high advantage, but it needs the step planetary gear gear.And the low speed outer rotor motor is simple in structure, and the former power density is lower, volume is bigger but compare, but this can be by coming balance owing to reduce the volume and the quality of the corresponding increase motor of speed changer.Therefore, the motor of these two kinds of forms is all used on modern electric automobile to some extent at present.
Compare with the traditional combustion engine automobile, the drive system arrangements of electric automobile has greater flexibility.The electric motor car that the wheel limit drives pattern has changed traditional centralized driving mode, is driven respectively on the wheel limit by four independent Electric Motor Wheel.Like this, the mechanical output that it has omitted orthodox car again to the transmittance process on wheel limit, has high efficiency advantage from the gearbox to the semiaxis.Particularly because the actuating force of each wheel is all directly accurately controlled, can and realizes driving automobile chassis dynamics Controlling functions such as anti-skidding, braking anti-lock and Stability Control easily, and can obtain splendid dynamics Controlling performance.Therefore taking turns limit driving pattern is the feasible Drive for EV form of a kind of advanced person.But Electric Motor Wheel has increased parts such as motor, reducing gear on the wheel limit, and the nonspring carried mass of automobile is increased, and will cause the ride comfort variation of automobile, and it is big that the dynamic loading of wheel becomes.For Electric Motor Wheel, lightweight is the emphasis and the difficult point of its design.
Summary of the invention
The utility model relate to be to provide a kind of in the wheel rim space planet carrier output type internal rotor integrated electric wheel of the integrated outside disk brake of integrate motor, planetary gear reducing mechanism and brake, this Electric Motor Wheel transmission of power approach and force-bearing situation are reasonable, each parts integrated level height, compact conformation can effectively be realized the lightweight of integrated electric wheel construction.
For achieving the above object, the technical solution adopted in the utility model is as follows:
The planet carrier output type internal rotor integrated electric wheel of a kind of integrated outside disk brake, comprise inner rotor motor, disk brake, wheel hub, planetary gear reducing mechanism, planetary gear reducing mechanism is by gear ring, planetary gear, planet carrier, sun gear is formed, the outside of hub for vehicle wheel is equipped with disk brake, and disk brake is built-in with the inner rotor motor that is connected with suspension, and the rotor of inner rotor motor is fixedlyed connected with sun gear, planet carrier cooperates fixedly connected with jack shaft, one end of jack shaft is fixedlyed connected with wheel hub by ring flange, and the other end penetrates in the rotor of inner rotor motor, and flexibly connects with rotor; Gear ring is fixed on the static electric machine casing.
Inner rotor motor is a non-brush permanent-magnet DC motor; Planetary gear reducing mechanism is that speed ratio is 3 NGW type planetary gear reducing mechanism; Planet carrier cooperates fixedly connected with jack shaft by spline with jack shaft.
The utility model adopts inner-rotor type integrated electric wheel mechanism arrangement, transmission of power approach and force-bearing situation reasonable, each parts integrated level height, and compact conformation has effectively been realized the lightweight of integrated electric wheel construction.As novel integrated Electric Motor Wheel, the utility model can directly apply to the electric automobile that wheel hub motor drives.
And have advantages such as light weight, power density is big, output torque is big, established important basis for exploitation based on four-wheel wheel hub motor driven vehicles high-performance chassis system, have very strong engineering specific aim, therefore have very important actual construction value.
Description of drawings
Fig. 1 is a structural configuration schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1, the planet carrier output type internal rotor integrated electric wheel of a kind of integrated outside disk brake, comprise inner rotor motor 100, disk brake 200, wheel hub 18, planetary gear reducing mechanism 300, planetary gear reducing mechanism 300 is by gear ring 4, planetary gear 5, planet carrier 6, sun gear 7 is formed, and the outside of wheel hub 18 is equipped with disk brake 200, disk brake 200 is built-in with the inner rotor motor 100 that is connected with suspension 9, the rotor 11 of inner rotor motor 100 is fixedlyed connected with sun gear 7, and planet carrier 6 cooperates fixedly connected with jack shaft 16, and an end of jack shaft 16 is fixedlyed connected with wheel hub 18 by ring flange 17 usefulness bolts 8, the other end penetrates in the rotor 11 of inner rotor motor 100, and flexibly connects with rotor 11; Gear ring 4 is fixed on the static electric machine casing 12.
It is non-brush permanent-magnet DC motor that the utility model adopts inner rotor motor 100, and the stator 10 of motor is fixed on the electric machine casing 12; Integrated planetary gear reducing mechanism 300 brake disc 1 of loop vent disk brake 200 is installed, and caliper 9 is installed on the suspension 15 for speed ratio is 3 NGW type planetary gear reducing mechanism on the wheel hub 18 of lateral wheel.Power is that the sun gear 7 of planet gear mechanism provides by motor internal rotor 11, because gear ring 4 is fixed on the static electric machine casing 12, so power passes to planet carrier 6 via planetary gear 5.Because planet carrier 6 links to each other by the jack shaft 16 of spline with the mechanism center, rotate again so can drive jack shaft 16 thus, and then by mounting flange 17 drive hubs 18 and even the rotation of whole wheel.
