Detailed description of the invention
Below in conjunction with embodiment and respective drawings, the technical solution of the utility model is described in detail, so that those skilled in the art can be more clearly understood from scheme of the present utility model, but and is not so limited protection domain of the present utility model.
For solving the technical problem in above-mentioned background technology, this utility model provides a kind of light-duty unit deceleration electric drive axle, conventional fossil fuel internal combustion engine is replaced to provide power for car load by motor, and utilize the speed reducer assembly of simple in construction described in the utility model to realize the reduction to motor speed and the raising of output moment of torsion, to adapt to the actually used of car load.
As it is shown in figure 1, in the present embodiment, a kind of light-duty single-stage speed reducing electric drive axle, it includes motor 1, main gearbox assembly 2, differential assembly 5；Wherein, main gearbox assembly 2 includes the first main shaft the 21, second main shaft the 22, the 3rd main shaft 23 and parking brake 3；It is provided with gear on first main shaft 21, the second main shaft 22 and the 3rd main shaft 23 are coaxially arranged with master gear and pinion respectively；First main shaft 21 is arranged at the outfan of motor 1, and its gear and the second main shaft 22 master gear external toothing, the second main shaft 22 pinion and the 3rd main shaft 23 master gear external toothing, the 3rd main shaft 23 pinion and differential assembly 5 gear external toothing.When motor 1 is in running order, the power of motor output is successively by motor 1 outfan, first main shaft the 21, second main shaft the 22, the 3rd main shaft 23, and eventually arrive at differential assembly 5, utilize the structure in above-mentioned main gearbox assembly 2 to be exported by the power in motor 1 and be sent to differential assembly 5, so that car load onward impulse is exported by motor 1 completely, it is achieved replaced traditional combustion engine by motor and cause the technical problem of energy waste and air pollution as car load power.
In the present embodiment, the speed ratio of main gearbox assembly 2 is 8～19.
In the present embodiment, main gearbox assembly 2 is made up of three grades of cylindric spiral gear systems, in order to optimize occlusion structure between gear, improves transmission efficiency.
