Description
Technical field
The utility model relates to a kind of pure electric automobile power assembly, especially relates to a kind of two permagnetic synchronous motor pure electric automobile power assembly.
Background technology
Existing pure electric automobile mostly is single motor and drives, and its defect is, when this motor breaks down, car load cannot be exercised, and automobile reliability is reduced.
Chinese patent (notification number CN203739605U, day for announcing 2014.07.30) discloses one and discloses a kind of pure electric vehicle and dual-motor drive system thereof, comprises the first drive motor, the second drive motor and the output shaft for being connected with vehicle bridge; Output shaft is interval with vertically the first transmission gear and the second transmission gear, the clutch end of the first drive motor is connected with the 3rd transmission gear engaged with the first transmission gear, the clutch end of the second drive motor is connected with the 4th transmission gear engaged with the second transmission gear.Analyzing and find, there is following defect in this patent:
(1) the 3rd transmission gear 3 and the 4th transmission gear 4 engage with the first transmission gear 1 and the second transmission gear 2 respectively, cause gear quantity too much, add cost;
(2) the 3rd transmission gears 3 and the 4th transmission gear 4 engage with the first transmission gear 1 and the second transmission gear 2 respectively, cause the axial dimension of output shaft 6 long, are unfavorable for mounting arrangements;
The power take-off shaft of (3) first drive motor is serially connected with second clutch, and this power-transfer clutch makes this system cost increase, reliability decrease.
Chinese patent (notification number CN201423906Y, day for announcing 2010.03.17) disclose a kind of double-motor power mixing driving device, comprise the first drive motor, the second drive motor and a power composite box, first drive motor is connected with power composite box respectively with the second drive motor, and power composite box comprises clutch end, auxiliary power input end, casing and is placed in the first input gear, the second input gear, the output gear in casing.Analyzing and find, there is following defect in this patent:
(1) power composite box comprises auxiliary power input end, and cause body structure complicated, cost increases.
Utility model content
The purpose of this utility model is exactly provide a kind of two permagnetic synchronous motor pure electric automobile power assembly to overcome defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of two permagnetic synchronous motor pure electric automobile power assembly, comprises the first motor, the second motor, also comprises the first gear, intermediate gear, the second gear, the first axle, tween drive shaft, the second axle.
The first described motor and the second motor are permagnetic synchronous motor.
The first described motor is connected with the first described axle, the first described gear engages with described intermediate gear, described intermediate gear and the second described gears meshing, the second described axle is connected with the second described motor, and assembly power is exported by described tween drive shaft.
The first described gear all only engages with described intermediate gear with the second described gear, the first described motor is directly connected by the first described axle with the first described gear, the second described motor is directly connected by the second described axle with the second described gear, and described tween drive shaft one end outputting power other end to be connected with casing by bearing but not to pass casing.
Compared with prior art, the utility model has the following advantages:
(1) first gear all only engages with intermediate gear with the second gear, decreases gear quantity, reduces cost;
(2) first gears all only engage with intermediate gear with the second gear, shorten tween drive shaft axial dimension, are beneficial to mounting arrangements;
(3) motor is directly connected by axle with gear, and axle does not connect power-transfer clutch, and make system architecture simple, cost is low, and reliability is high;
(4) tween drive shaft only has one end to pass casing, and make body structure simple, be easy to processing, cost reduces.
Accompanying drawing explanation
Fig. 1 is the first structural representation of the present utility model.
Fig. 2 is the second structural representation of the present utility model.
In figure: 1 be the first motor, 2 is the second motor, 3 be the first gear, 4 is intermediate gear, 5 to be the second gear, 6 be the first axle, 7 for tween drive shaft, 8 be the second axle.
Detailed description of the invention
Below the utility model is described further.
