Abstract
The invention relates to a double-motor input wheel-side speed reducer for an electric bus. The double-motor input wheel-side speed reducer comprises a planetary gear speed reducer arranged in a wheel, wherein a wheel shaft is arranged in the planetary gear speed reducer; a driven bevel gear is arranged on the wheel shaft; two driving bevel gears are arranged on the outer side of the driven bevel gear and meshed with the driven bevel gear; meshed points between the two driving bevel gears and the driven bevel gear averagely divide the circumference of the driven bevel gear; and each driving bevel gear is driven by a driving motor. The double-motor input wheel-side speed reducer provided by the invention is suitable for electric buses.
Description
Technical field
The present invention relates to a kind of electrobus with double-motor wheel for inputting side reducer.
Background technology
At present the wheel reduction gear used of electrobus is generally single motor input, and it is through a drive motor that is arranged on the axletree sidepiece, through the transmission of drive bevel gear and driven wheel of differential, thus the running of realization axletree.Its shortcoming is: because axletree is monolateral stressed, can cause the operation of axletree not steady, influence the service life of parts; In addition, the mode of single motor input necessarily requires the modulus of drive bevel gear and driven wheel of differential bigger, not only can influence the stationarity of transmission, and can produce big noise.
Summary of the invention
Technical matters to be solved by this invention is: provide a kind of and can make electrobus that axletree operates steadily with double-motor wheel for inputting side reducer.
For addressing the above problem; The technical scheme that the present invention adopts is: electrobus is with double-motor wheel for inputting side reducer; Comprise being arranged on epicyclic reduction gear in the wheel that be provided with axletree in the epicyclic reduction gear, said axletree is provided with driven wheel of differential; The arranged outside of driven wheel of differential has two drive bevel gear; Two drive bevel gear are meshed with driven wheel of differential, and the point of engagement of two drive bevel gear and driven wheel of differential divide the circumference of driven wheel of differential equally, and each drive bevel gear is respectively by a drive motor drives.
The invention has the beneficial effects as follows: above-mentioned electrobus is with double-motor wheel for inputting side reducer, and it is simple in structure, easy to use, and it is through the mode of double-motor input; Can make axletree is that bilateral symmetry is stressed; Thereby axletree is operated steadily, improve the service life of parts, and the modulus of drive bevel gear and driven wheel of differential can reduce; Not only transmission stability can be improved, and noise can be reduced.
Description of drawings
Fig. 1 is a structure diagram of the present invention;
Among the figure: 1, wheel, 2, epicyclic reduction gear, 3, axletree, 4, driven wheel of differential, 5, drive bevel gear, 6, drive motor.
The specific embodiment
Through specific embodiment electrobus of the present invention is done further to describe in detail with double-motor wheel for inputting side reducer below.
As shown in Figure 1; Electrobus is with double-motor wheel for inputting side reducer; Comprise the epicyclic reduction gear 2 that is arranged in the wheel 1, be provided with axletree 3 in the epicyclic reduction gear 2, said axletree 3 is provided with driven wheel of differential 4; The arranged outside of driven wheel of differential 4 has two drive bevel gear 5; Two drive bevel gear 5 are meshed with driven wheel of differential 4, and two drive bevel gear 5 divide the circumference of driven wheel of differential 4 equally with the point of engagement of driven wheel of differential 4, and each drive bevel gear 5 is driven by a drive motor 6 respectively.
The invention has the beneficial effects as follows: above-mentioned electrobus is with double-motor wheel for inputting side reducer, and it is simple in structure, easy to use, and it is through the mode of double-motor input; Can make axletree 3 stressed for bilateral symmetry; Thereby axletree 3 is operated steadily, improve the service life of parts, and the modulus of drive bevel gear 5 and driven wheel of differential 4 can reduce; Not only transmission stability can be improved, and noise can be reduced.
The above embodiments are the principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used to limit the present invention; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
Claims (1)
