Description
Technical field
The utility model belongs to the vehicle technology field, specifically, and the particularly wheel hub motor double clutch planetary shift mechanism in the electric motor car.
Background technology
At present, the electric vehicle motor of producing on the market is to reach infinitely variable speeds by electronic controller, and its rotating speed can be from zero to rated value, and the engine throttle speed change compares, and the speed change of motor is more steady.But the method that adopts electronic controller to carry out speed change has very large deficiency: when climbing and loading, the continuous increase by electric current during machine operation increases torque, changes climbing capacity with this.Therefore, the large electric current of torque is just large, and the output torque of motor is little, and power consumption is large, and the ability that continues shortens widely.
The producer that has integrates the wheel hub motor of planetary gears and electric motor car, carries out speed change by planetary gears.But in speed change, gear need to be moved axially, could realize to change the engagement object.When speed or in the situation of climbing, loading, cause easily gear to break, and the stationarity of gearshift is relatively poor, car load is easily shaken during gearshift, can affect the comfortableness of driving.Simultaneously, existing wheel hub motor gear changing mechanism complex structure, assembling difficulty, volume are large, production cost is high, are unfavorable for the large-scale promotion use.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of gearshift steady, the wheel hub electric motor of electric vehicle double clutch planetary shift mechanism of ability and the climbing capacity of can Effective Raise continuing.
The technical solution of the utility model is as follows: a kind of wheel hub electric motor of electric vehicle double clutch planetary shift mechanism, comprise wheel hub (25), it is characterized in that: described wheel hub (25) is supported on the motor shaft (5) by bearing, at motor shaft (5) suit motor housing (8), this motor housing (8) connects fixing with wheel hub (25); Motor inner casing (1) is set in described motor housing (8), magnetic links (7) is housed on the inwall of this motor inner casing (1), and stator (6) is set in motor inner casing (1), stator (6) is placed on the motor shaft (5) admittedly; The two ends of described motor inner casing (1) are respectively by the first inner end cap (2) and the second inner end cap (3) sealing, these two inner end cap (2,3) all be bearing on the motor shaft (5) by bearing, be provided with at least two the first planetary gears (9) on the next door of described the first inner end cap (2), all the first planetary gears (9) all are meshed with the first sun gear (13), this the first sun gear (13) kink is on motor shaft (5), and the first sun gear (13) fixes with the first inner end cap (2); Described the first planetary gear (9) is positioned at wheel hub (25), corresponding second planetary gear (12) of each first planetary gear (9), the first planetary gear (9) is by planet axis (23) and the connection of corresponding the second planetary gear (12), described planet axis (23) is located on the planet carrier (10), and this planet carrier (10) is connected with motor shaft (5) by standard rolling bearing mono-directional overrun clutch (14); All the second planetary gears (12) all are meshed with the second sun gear (15), this second sun gear (15) fixes with the wheel hub connection (24) of wheel hub (25) inside, and the second sun gear (15) is connected with motor shaft (5) by the controllable bidirectional clutch.
