Embodiment
With reference to embodiments and technical scheme is described in detail respective drawings, so that this Art personnel can be more clearly understood from the solution of the present invention, but and be not so limited the present invention's Protection domain.
To solve the technical problem in above-mentioned background technology, the present invention provides a kind of light-duty unit deceleration electricity and driven Dynamic bridge, replaces conventional fossil fuel internal combustion engine to provide power for vehicle, and utilize institute of the present invention by motor The speed reducer assembly simple in construction stated realizes reduction and the raising of output torque to motor speed, with Adapt to the actual use of vehicle.
As shown in figure 1, in the present embodiment, a kind of light-duty single-stage speed reducing electric drive axle, it includes electricity Machine 1, main gearbox assembly 2, differential assembly 5；Wherein, main gearbox assembly 2 includes first Main shaft 21, the second main shaft 22, the 3rd main shaft 23 and EPB 3；Set on first main shaft 21 Have and be coaxially arranged with master gear and pinion respectively on gear, the second main shaft 22 and the 3rd main shaft 23；The One main shaft 21 is arranged at the output end of motor 1, and its gear and the master gear external toothing of the second main shaft 22, The pinion of second main shaft 22 and the master gear external toothing of the 3rd main shaft 23, the pinion of the 3rd main shaft 23 with it is poor The fast gear external toothing of device assembly 5.When motor 1 is in running order, the power of motor output is successively By the output end of motor 1, the first main shaft 21, the second main shaft 22, the 3rd main shaft 23, and eventually arrive at difference Fast device assembly 5, is transmitted the power output in motor 1 using the structure in above-mentioned main gearbox assembly 2 To differential assembly 5, so that vehicle onward impulse is exported by motor 1 completely, realization is replaced by motor Change the technical problem that traditional combustion engine causes energy waste and air pollution as vehicle power.
