Background technology
Electro-tricycle mainly is applicable to vast friend peasant, especially aspect production needs, but rural area road conditions complexity, the picture mire, the road surface is rough and uneven in surface, the gradient is big. soft spots of road bed etc., motor is wanted a large amount of electric energy of overload consumption when travelling on these abominable road surfaces, may burn out motor, controller, components and parts such as wire harness.
The utility model content
Technical problem to be solved in the utility model provides the automobile-used transaxle of a kind of electric three-wheel, makes that motor can alleviate overload when travelling on abominable road surface, thereby reduces consumed power, and mileages of continuation is long.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The automobile-used transaxle of a kind of electric three-wheel, include gearbox body, it is characterized in that: parallel rotation is equipped with rotating shaft one, rotating shaft two, rotating shaft three, diff on the described gearbox body, one end of described rotating shaft one is connected with machine shaft, and rotating shaft one two ends are separately installed with high speed driving gear, low-speed active gear; Described rotating shaft two two ends are rotatablely equipped with low speed driven gear and high speed driven gear respectively, high speed driving gear, low-speed active gear mesh with high speed driven gear and low speed driven gear respectively, be provided with in the middle of the rotating shaft two by keyway and the cliding gear of key along two axial sliding fits of rotating shaft, the both ends of the surface of cliding gear link by the realization that cooperatively interacts of groove and projection respectively and between the adjacent surface end face of low speed driven gear and high speed driven gear; On the described cliding gear fork slot is arranged, shifting fork device is installed on the gearbox body cooperates, realize endwisely slipping of cliding gear with described fork slot; Be installed with three big gear wheels, three miniature gearss in the described rotating shaft three; Described differential casing external fixation is equipped with the diff big gear wheel, diff big gear wheel and three pinion.
If main transformer speed shift fork is stirred cliding gear to low speed side, cliding gear and the interlocking of low speed driven gear, then cliding gear and low speed driven gear are synchronous, and the power of motor reaches cliding gear by rotating shaft once the low speed driven gear, the high speed driven gear idle running in the rotating shaft at this moment two; If main transformer speed shift fork is stirred cliding gear to high speed side, cliding gear and the interlocking of high speed driven gear, then cliding gear and high speed driven gear are synchronous, the power of motor reaches cliding gear by the high speed driving gear above the rotating shaft one through the high speed driven gear, at this moment the low speed driven gear idle running in the rotating shaft two, three canine tooth crop rotations that reached in the rotating shaft three by cliding gear are further slowed down then, reach the diff big gear wheel again, export wheel to by diff at last.
The utility model has the advantages that:
The utility model can alleviate overload, power saving, and mileages of continuation is long, and torsion is big, uses reliably, and range of use is wider.
