Abstract
The utility model discloses a replaceable driving bridge of an electric vehicle. The replaceable driving bridge comprises a driving device, a speed changing device, a differential mechanism, a haft shaft casing pipe fixedly arranged on a vehicle body, and two half shafts respectively connected with the differential mechanism; the half shafts are mounted inside the half shaft casing pipe; the driving device drives the differential mechanism to rotate through the speed changing device; the replaceable driving bridge further comprises a gearbox body; the differential mechanism and the speed changing device are mounted inside the gearbox body; and the driving device is fixedly connected outside the gearbox body. According to the replaceable driving bridge provided by the utility model, the driving device is independently designed outside the gearbox body, and is separated from the half shaft casing pipe, so that the driving device is convenient to replace. Furthermore, the gearbox body is internally maintained, so that the maintenance cost is reduced, and the replaceable driving bridge has a simpler structure.
Description
Technical field
The utility model relates to a kind of changeable type drive axle of battery-driven car, belongs to the differential drive axle technical field of structures.
Background technology
At present, China Patent Publication No. CN101348075A discloses a kind of motor-driven drive axle and China Patent Publication No. CN101323253A discloses a kind of differential drive axle, the structure of these drive axles, motor all is fixed in the gearbox body, if motor damages, during maintenance, need to take gearbox body apart, very inconvenient, maintenance cost is higher.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of changeable type drive axle of simple in structure, the battery-driven car of being convenient to keep in repair and change force piece is provided.
The technical scheme that realizes the utility model purpose is: a kind of changeable type drive axle of battery-driven car, axle tube on comprising actuating device, transmission system, diff and being connected vehicle body and two semiaxis that are connected with diff respectively, semiaxis is installed in the axle tube, actuating device drives differential mechanism rotating by transmission system, also comprise gearbox body, described diff and transmission system are installed in the gearbox body, and actuating device is fixedly connected on outside the gearbox body.
Further, described transmission system is comprised of the first flower wheel, the second flower wheel and driven wheel and the first order transmission shaft and the second stage transmission shaft that can be rotated to support on respectively on the gearbox body, first order transmission shaft is connected with described actuating device, driven wheel is sleeved on the first order transmission shaft, the first flower wheel and the second flower wheel all are sleeved on the transmission shaft of the second stage, driven wheel and the first flower wheel are meshed, and the second flower wheel is meshed with described diff.
After having adopted technique scheme, the actuating device outputting power is after the transmission system deceleration, pass to diff, again by diff with transmission of power to semiaxis, thereby the wheel hub that drives both sides rotates, and realizes normally travelling of vehicle, the utility model with the actuating device independent design outside gearbox body, and and axle tube separate, be convenient to change actuating device, and to the maintenance of gearbox body inside, reduced maintenance cost, and structure is simpler.
Description of drawings
Fig. 1 is the structure cutaway view of the changeable type drive axle of battery-driven car of the present utility model.
The specific embodiment
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model according to specific embodiment also by reference to the accompanying drawings,
As shown in Figure 1, a kind of changeable type drive axle of battery-driven car, axle tube 3 on comprising actuating device 1, transmission system, diff 2 and being connected vehicle body and two semiaxis 4 that connect of being connected with diff respectively, semiaxis 4 is installed in the axle tube 3, actuating device 1 drives diff 2 rotations by transmission system, also comprise gearbox body 5, diff 2 and transmission system are installed in the gearbox body 5, and actuating device 1 is fixedly connected on outside the gearbox body 5.Transmission system is comprised of the first flower wheel 6, the second flower wheel 7 and driven wheel 8 and the first order transmission shaft 9 and the second stage transmission shaft 10 that can be rotated to support on respectively on the gearbox body 5, first order transmission shaft 9 is connected with actuating device 1, driven wheel 8 is sleeved on the first order transmission shaft 9, the first flower wheel 6 and the second flower wheel 7 all are sleeved on the second stage transmission shaft 10, driven wheel 8 and the first flower wheel 6 are meshed, and the second flower wheel 7 is meshed with described diff 2.
Actuating device 1 can adopt DC machine.
Principle of work of the present utility model is as follows:
Actuating device 1 outputting power, after slowing down by transmission system, pass to diff 2, again by diff 2 with transmission of power to semiaxis 4, thereby the wheel hub 11 that drives both sides rotates, realize normally travelling of vehicle, the utility model with actuating device 1 independent design outside gearbox body 5, and and axle tube 3 separate, be convenient to change actuating device 1, and to the maintenance of gearbox body 5 inside, reduced maintenance cost, and structure is simpler.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
