Description
Technical field
The present invention relates to a kind of battery-driven car, specifically is a kind of double-motor driving structure of battery-driven car.
Background technology
Present battery-driven car all is single motor-driven, drive motor is set in the hub shell usually, drive motor is given wheel hub by wheel hub end housing with power transmission, battery-driven car is owing to be subjected to restrictions such as weight, volume, the power of drive motor can not be very big, current of electric was bigger when ubiquity started, and started the propulsive effort deficiency, so battery-driven car startup acceleration capability is not good; When acclive road traveling, also there is the situation of above-mentioned under power in addition.
Summary of the invention
The object of the invention is to have additional a high-revolving auxiliary-motor in existing conventional wheel hub electric motor of electric vehicle outside, control the operating mode of this auxiliary-motor by controller for electric vehicle, when battery-driven car when propulsive effort is not enough, auxiliary-motor is got involved battery-driven car rapidly and is travelled in the Dual-motors Driving mode, to overcome the deficiency that present battery-driven car exists, the present invention can increase the mileages of continuation of battery-driven car and increase output torque.
The present invention is achieved in that
A kind of double electric motor driving structure for electric vehicle, comprise main motor, hub shell, wheel hub end housing and main shaft, main motor is arranged in the hub shell, main motor output end and wheel hub end housing link, it is characterized in that: have an auxiliary-motor to link by reducing gearbox and wheel hub end housing, auxiliary-motor is connected on the housing of reducing gearbox, and reducing gearbox is connected on wheel hub end housing and the main shaft and with vehicle frame by bearing carrier ring and is connected.
Described reducing gearbox comprises case shell, case lid, train of reduction gears and unilateral bearing; Be provided with an annular around the axis hole in the described wheel hub end housing outside and connect boss; The case shell is connected on this annular by bearing carrier ring and connects on the boss, case lid then is connected on the main shaft by bearing carrier ring, gear cluster and unilateral bearing are meshing with each other and are arranged on the sealing of case shell and case lid and form in the casing, unilateral bearing is socketed in above-mentioned annular and connects on the boss, auxiliary-motor is connected in the outside of reducing gearbox, and the mouth of auxiliary-motor is meshed with train of reduction gears.
Described annular connects on the boss establishes the two-stage step, and the case shell is by the bearing carrier ring step place higher in inside, and one-way shaft is accepted and is socketed in outside lower step place.
When the present invention started at battery-driven car, the major-minor motor put into operation, and after starting was normal, auxiliary-motor quit work automatically, and main motor continues normal operation; As master's motor load surpasses the busy hour of setting when climbing, and the auxiliary-motor thigh is gone into work increasing output torque, thereby improves hill climbing ability; And when load diminishes, auxiliary-motor just quits work and is worked on saves energy by the single motor of main motor, the running condition that controller of the present invention detects main motor is touched the auxiliary-motor mode of operation, to improve the work efficiency of motor, increase the battery-driven car output torque, and saves energy, increase mileages of continuation to reach.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a lateral plan of the present invention;
Fig. 3 be Fig. 2 A-A to portion's view.
The specific embodiment
As Figure 1-3, a kind of double electric motor driving structure for electric vehicle, comprise main motor, hub shell, wheel hub end housing 1 and main shaft 2, main motor is arranged in the hub shell, main motor output end and wheel hub end housing 1 link, have an auxiliary-motor 3 to link by reducing gearbox 4 and wheel hub end housing 1, reducing gearbox 4 is fixed on the vehicle frame, and described reducing gearbox 4 comprises case shell 41, case lid 42, train of reduction gears 43 and unilateral bearing 44; Be provided with an annular around the axis hole in described wheel hub end housing 1 outside and connect boss 11, described annular connects on the boss 11 establishes the two-stage step; Case shell 41 is connected on this annular by bearing carrier ring and connects higher step place, boss 11 inside, case lid 42 then is connected on the main shaft 2 by bearing carrier ring, train of reduction gears 43 and unilateral bearing 44 are meshing with each other and are arranged on 42 sealings of case shell 41 and case lid and form in the casing, one-way shaft bearing sleeve 44 is connected on above-mentioned annular and connects lower step place, boss 11 outsides, auxiliary-motor 3 is connected in the casing outside of reducing gearbox 4, and the mouth 31 of auxiliary-motor 3 is meshed with train of reduction gears 43.
Battery-driven car is when starting, two motors of major-minor put into operation simultaneously, the mouth 31 of auxiliary-motor 3 is given unilateral bearing 44 by train of reduction gears 43 with the power transmission of output, unilateral bearing 44 drives wheel hub end housing 1, two motors increase output torque of working simultaneously, alleviate the load of main motor, improved the work efficiency and the saves energy of motor; Behind the battery-driven car cruising, auxiliary-motor 3 quits work automatically, and main motor works on, adopt unilateral bearing 44 to connect between auxiliary-motor 3 and the wheel hub end housing 1, when auxiliary-motor 3 stopped, unilateral bearing 44 can play the effect that auxiliary-motor 3 separates with wheel hub end housing 1, kept the cruising of battery-driven car; When battery-driven car travels to the climbing highway section or load when increasing suddenly, when the controller of motor detects working current and increases suddenly, can touch auxiliary-motor work at once, to increase the output torque of battery-driven car, improve hill climbing ability; Load when reducing and arrive battery-driven car, controller can switch to auxiliary-motor intelligence halted state, to reach the purpose of saves energy.
