Abstract
The utility model provides an integrated rear axle of an electric motor, and the integrated rear axle is simple and compact in structure, long in service life and convenient to maintain. The integrated rear axle comprises a transmission shaft, a rear axle frame installed on the transmission shaft and two driving wheels. The rear axle frame is provided with an electric reduction box and a driving bevel gear, and a driven bevel gear meshed with the driving bevel gear is fixed on the transmission shaft. The integrated rear axle is simple and compact in structure, the electric motor, the reduction box and the rear axle are integrated, the two driving wheels are directly driven by the bevel gears, transmission is stable, transmission friction loss is greatly reduced, output power loss is little, service life is long, and maintenance is convenient.
Description
Technical field
The utility model relates to a kind of motor apparatus, the integrated back axle of especially a kind of electrical motor.
Background technology
Present commercially available battery-driven car speed change system is that electrical motor is from the band portion transmitter, transmission output shaft drives battery-driven car by sprocket wheel, chain, tween drive spindle etc. again, complex structure, manufacturing cost height, transmission process parts frictional loss is big, driving chain comes off from sprocket wheel easily, the horsepower output loss is big, maintenance trouble, car load repair rate height.
The utility model content
The integrated back axle of electrical motor that the purpose of this utility model provides a kind of simple in structure, compact, long service life, is convenient to keep in repair.
Realize the integrated back axle of electrical motor of the utility model purpose, comprise transmission shaft, be installed in rear axle stand and two driving wheels on the transmission shaft; Described rear axle stand is provided with electric reducer and drive bevel gear, fixedly has on the described transmission shaft and the driven wheel of differential of described drive bevel gear to engagement.
Be provided with bearing between described rear axle stand and the transmission shaft.
Be provided with fixed beam in the middle of the described rear axle stand, be used for fixedly electric reducer and drive bevel gear.
The beneficial effect of the integrated back axle of electrical motor of the present utility model is as follows:
The integrated back axle of electrical motor of the present utility model is simple in structure, compact, and electrical motor, retarder, back axle are arranged to one, directly drives two driving wheels by finishing bevel gear cuter, stable drive, significantly reduce gearing friction consume, the horsepower output loss is little, long service life and be convenient to maintenance.
Description of drawings
Fig. 1 is the structural representation of the integrated back axle of electrical motor of the present utility model.
The specific embodiment
Embodiment of the present utility model is as follows: as shown in Figure 1, the integrated back axle of electrical motor of the present utility model comprises transmission shaft 2, is installed in rear axle stand 1 and two driving wheels 3 on the transmission shaft 2; Described rear axle stand 1 is provided with electric reducer 4 and drive bevel gear 5, fixedly has on the described transmission shaft 2 and the driven wheel of differential 6 of described drive bevel gear 5 to engagement.
Be provided with bearing between described rear axle stand 1 and the transmission shaft 2.
Be provided with fixed beam in the middle of the described rear axle stand 1, be used for fixedly electric reducer 4 and drive bevel gear 5.
The integrated back axle of electrical motor of the present utility model, it is simple in structure, compact, because electrical motor, retarder, back axle are arranged to one, directly drive two driving wheels by finishing bevel gear cuter, its stable drive, significantly reduce gearing friction consume, the horsepower output loss is little, long service life and be convenient to maintenance.
Embodiment recited above is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; design under the spiritual prerequisite not breaking away from the utility model; various distortion and improvement that the common engineering staff in this area make technical solutions of the utility model all should fall in the definite protection domain of claims of the present utility model.
