In addition, coaxiality requirement of mounting of the connecting device is lowered, and the connecting device of the motor and the reduction gearbox in the electric automobile is convenient to install and high in transmission efficiency.
Description
[technical field]
The utility model relates to the whole drive-type automobile axle structure of electronlmobil, specifically is meant the motor of whole drive-type automobile axle and the connecting device of drop-gear box.
[background technology]
The location arrangements of traditional retarder, diff, semiaxis and propulsion source in the traditional integral drive-type automobile axle structure is separated by far away; The middle need adopts transmission devices such as axle drive shaft and universal driving device to connect through change speed gear box one-level speed change again; Such structure; Not only take up space bigger, cost is higher, thereby and cause driving efficiency relatively low because of the course of torque transfer is long.
Electronlmobil is different with orthodox car on energy sources and type of drive with orthodox car, and orthodox car changes the speed of a motor vehicle through change speed gear box usually, but electronlmobil can be realized speed of a motor vehicle control through the control rotating speed of motor.Owing to the difference of speed change pattern, cause the difference of structure aspects.Motor and drop-gear box be integrated to have compact conformation, and driving efficiency is high, the advantage that is easy to arrange.Can effectively save installing space.But this structure proposes high requirement to the power transmission pattern of motor and drop-gear box, and the quality of type of drive can exert an influence to the life-span of motor and drop-gear box.Motor output and drop-gear box input driving device work under bad environment are easy to occur to damage the problem with high noisy.Motor shaft is with the mode and the drop-gear box direct connection of axle head female splines in the prior art, and the difficulty of processing of expanded motor axle is difficult for changing, setting accuracy has relatively high expectations.
[utility model content]
The utility model technical matters to be solved is to provide a kind of motor easy, that driving efficiency is high and connecting device of drop-gear box processed.
The utility model adopts following technical scheme to solve the problems of the technologies described above:
The connecting device of motor and drop-gear box in the electronlmobil comprises that a diff, two-semiaxle, two bridge tubes, a Qiao Bao and a front end are provided with the motor of output shaft, and said two bridge tubes are sheathed on the surface of two-semiaxle respectively, and two these bridge tubes are connected through the bridge bag; Two mouths of said diff are connected with a joggle with two-semiaxle respectively; And this diff is positioned at the bridge bag, comprises that also one is positioned at the drop-gear box of bridge bag, and this drop-gear box and diff are connected with a joggle; The front end of said motor docks with the attachment face of bridge bag; The rear end of this motor is connected with bridge tube, and said drop-gear box is provided with an input shaft, and this input shaft is a castellated shaft; The output shaft of said motor also is a castellated shaft; Be connected through a spline housing between the input shaft of said drop-gear box and the output shaft of said motor.
The front end of said motor is provided with threaded mounting hole, and this threaded mounting hole docks interlocking through bolt with the attachment face of bridge bag.
The rear end of said motor is connected with bridge tube through a mounting bracket.
The advantage of the utility model is: connection mode is simple, is easy to realize that for ease of maintenaince, compact conformation can effectively be practiced thrift installing space.Can reduce the right alignment requirement of installation, be convenient to install, driving efficiency is high.
[description of drawings]
Combine embodiment that the utility model is done further to describe with reference to the accompanying drawings.
Fig. 1 is the utility model structural representation.
Fig. 2 is a spline housing structural representation in the utility model.
[specific embodiment]
See also Fig. 1; The connecting device of motor and drop-gear box in the electronlmobil; Comprise a diff 1, two-semiaxle 2, two bridge tubes 3, be located at bridge bag (not shown) between two bridge tubes 3, motor 4 that a front end 41 is provided with output shaft (not shown), and one be positioned at the bridge bag drop-gear box 5; This drop-gear box 5 is connected with a joggle with diff 1, and said two bridge tubes 3 are sheathed on the surface of two-semiaxle 2 respectively, and two these bridge tubes 3 are connected through the bridge bag; Two mouths of said diff 1 are connected with a joggle with two-semiaxle 2 respectively; And this diff 1 is positioned at the bridge bag; The front end 41 of said motor 4 docks with the attachment face of bridge bag; The rear end 42 of this motor 4 is connected with bridge tube 3, and said drop-gear box 5 is provided with an input shaft (figure does not show), and this input shaft is a castellated shaft; The output shaft of said motor also is a castellated shaft; Be connected through a spline housing 10 between the input shaft of said drop-gear box and the output shaft of said motor.Spline housing 10 structures are as shown in Figure 2.
In addition, in the present embodiment, the front end 41 of motor 4 is provided with threaded mounting hole (not shown), and this threaded mounting hole generally forms the state of interlocking that docks through bolt (not shown) with the attachment face of bridge bag; The rear end of motor 4 is connected with bridge tube 3 through mounting bracket 6.
The beneficial effect of the utility model is: connection mode is simple, is easy to realize that for ease of maintenaince, compact conformation can effectively be practiced thrift installing space.Can reduce the right alignment requirement of installation, be convenient to install, driving efficiency is high.
Product form of the foregoing description and graphic and non-limiting the utility model and style, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing.
