Description

A kind of rear axle of electric automobile of modified node method
Technical field
The utility model relates to a kind of motor rear axle of modified node method, belongs to electronlmobil accessory field.
Background technology
Rear axle of electric automobile steel pipe two ends are equipped with semiaxis for installing wheel hub, and it is the important accessory of composition electronlmobil.The gap of traditional rear axle of electric automobile semiaxis distance axle bearing is very large, the outstanding liter of rear axle shaft is oversize, the load capacity of semiaxis will be caused like this to reduce, half spindle nose easily ruptures, affect the service life of back axle entirety on the one hand, in use also can there is great potential safety hazard on the other hand, can not user demand be met.Therefore, a kind of new technical scheme should be provided to solve the problem.
Summary of the invention
The purpose of this utility model is: for above-mentioned deficiency, provides a kind of rational in infrastructure, the rear axle of electric automobile of the modified node method that result of use is good.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of rear axle of electric automobile of modified node method, comprise back axle steel pipe, semiaxis, drg and for the bearing of fixing semiaxis and bearing seat, described drg is installed on mounting seat of brake, the side of mounting seat of brake is located at by described back axle steel pipe, and its end is fixedly connected with mounting seat of brake, partly be located in the opposite side of mounting seat of brake, described bearing and bearing seat are located at the inside of mounting seat of brake, and the side of described bearing is provided with bearing locating bush.
Further technical scheme: be provided with lining between described bearing seat and bearing locating bush.
Due to the application of technique scheme, the utility model compared with prior art tool has the following advantages:
Rear axle of electric automobile of the present utility model, rational in infrastructure, bearing and bearing seat are located at the inside of mounting seat of brake, the distance between Hub mounting surface on axle bearing to semiaxis can be shortened, substantially increasing the load capacity of semiaxis, the load capacity of back axle can be made when not changing axle bearing neck size to improve 1.5-2 doubly.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model embodiment one structural representation.
In above accompanying drawing: 1, back axle steel pipe, 2, semiaxis, 3, drg, 4, mounting seat of brake, 5, bearing, 6, bearing seat, 7, bearing locating bush, 8, lining, 9, Hub mounting surface.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment one:
As shown in Figure 1, the rear axle of electric automobile of a kind of modified node method of the utility model, comprise back axle steel pipe 1, semiaxis 2, drg 3 and for the bearing 5 of fixing semiaxis and bearing seat 6, drg 3 is installed on mounting seat of brake 4, the side of mounting seat of brake is located at by back axle steel pipe 1, and its end is fixedly connected with mounting seat of brake 4, and semiaxis 2 is located at the opposite side of mounting seat of brake 4, bearing 5 and bearing seat 6 are located at the inside of mounting seat of brake 4, and the side of bearing 5 is provided with bearing locating bush 7.
Preferably, as an embodiment, between bearing seat 6 and bearing locating bush 7, be provided with lining 8.
The rear axle of electric automobile of modified node method of the present utility model, bearing 5 and bearing seat 6 are located at the inside of mounting seat of brake 4, the distance between Hub mounting surface 9 on axle bearing 5 to semiaxis can be shortened, substantially increasing the load capacity of semiaxis 2, the load capacity of back axle can be made when not changing axle bearing neck size to improve 1.5-2 doubly.Meanwhile, the utility model adopts heavy serial bearing, and when not affecting installation, the size (increasing to Φ 40 by original Φ 30) increasing the bearing neck of semiaxis can make again the load capacity of back axle improve 1.5-2 doubly.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
