Abstract
The present invention relates to the motor rear axle of a kind of improved structure, belong to electric automobile accessory field.The technical solution used in the present invention is: the rear axle of electric automobile of a kind of improved structure, including back axle steel pipe, semiaxis, brake and for fixing bearing and the bearing block of semiaxis, brake is installed on mounting seat of brake, the side of mounting seat of brake is located at by back axle steel pipe, and its end and mounting seat of brake are fixing is connected, partly being located in the opposite side of mounting seat of brake, bearing and bearing block and be located at the inside of mounting seat of brake, the side of bearing is provided with bearing positioning sleeve.The invention have the advantage that rational in infrastructure, bearing and bearing block are located at the inside of mounting seat of brake, axle bearing distance to semiaxis between Hub mounting surface can be shortened, substantially increase the load-carrying ability of semiaxis, the load-carrying ability of back axle can be made in the case of not changing axle bearing neck size to improve 1.5-2 times.
Description
Technical field
The present invention relates to the motor rear axle of a kind of improved structure, belong to electric automobile accessory neck
Territory.
Background technology
Rear axle of electric automobile steel pipe two ends are equipped with semiaxis for installing wheel hub, and it is that composition is electronic
The important accessory of automobile.The gap of traditional rear axle of electric automobile semiaxis distance axle bearing is very
Greatly, the outstanding liter of rear axle shaft is oversize, and the load-carrying ability that so will result in semiaxis reduces, half spindle nose
It is easily broken off, on the one hand affects the service life that back axle is overall, on the other hand the most also can
There is great potential safety hazard, it is impossible to meet use demand.Therefore, it should provide a kind of new
Technical scheme solves the problems referred to above.
Summary of the invention
It is an object of the invention to: for above-mentioned deficiency, it is provided that a kind of rational in infrastructure, use effect
The rear axle of electric automobile of the best improved structure.
For achieving the above object, the technical solution used in the present invention is:
A kind of rear axle of electric automobile of improved structure, including back axle steel pipe, semiaxis, brake with
And for fixing bearing and the bearing block of semiaxis, described brake is installed on mounting seat of brake
On, the side of mounting seat of brake is located at by described back axle steel pipe, and its end is installed with brake
Seat is fixing to be connected, and is partly located in the opposite side of mounting seat of brake, and described bearing and bearing block set
In the inside of mounting seat of brake, the side of described bearing is provided with bearing positioning sleeve.
Further technical scheme: be provided with lining between described bearing block and bearing positioning sleeve.
Due to the application of technique scheme, the present invention compared with prior art has the most excellent
Point:
The rear axle of electric automobile of the present invention, rational in infrastructure, bearing and bearing block are located at brake
The inside of mounting seat, can shorten axle bearing distance to semiaxis between Hub mounting surface,
Substantially increase the load-carrying ability of semiaxis, permissible in the case of not changing axle bearing neck size
The load-carrying ability making back axle improves 1.5-2 times.
Accompanying drawing explanation
Accompanying drawing 1 is the embodiment of the present invention one structural representation.
In the figures above: 1, back axle steel pipe, 2, semiaxis, 3, brake, 4, brake
Mounting seat, 5, bearing, 6, bearing block, 7, bearing positioning sleeve, 8, lining, 9, wheel hub
Installed surface.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the invention will be further described:
Embodiment one:
As it is shown in figure 1, the rear axle of electric automobile of a kind of improved structure of the present invention, including back axle steel
Pipe 1, semiaxis 2, brake 3 and for fixing bearing 5 and the bearing block 6 of semiaxis, system
Dynamic device 3 is installed on mounting seat of brake 4, and the one of mounting seat of brake is located at by back axle steel pipe 1
Side, and its end and mounting seat of brake 4 is fixing is connected, semiaxis 2 is located at mounting seat of brake
The opposite side of 4, bearing 5 and bearing block 6 are located at the inside of mounting seat of brake 4, bearing 5
Side be provided with bearing positioning sleeve 7.
Preferably, as an embodiment, between bearing block 6 and bearing positioning sleeve 7, it is provided with lining
Set 8.
The rear axle of electric automobile of the improved structure of the present invention, is located at system by bearing 5 and bearing block 6
The inside of dynamic device mounting seat 4, can shorten axle bearing 5 to semiaxis Hub mounting surface 9 it
Between distance, substantially increase the load-carrying ability of semiaxis 2, do not changing axle bearing neck size
In the case of can make back axle load-carrying ability improve 1.5-2 times.Meanwhile, the present invention uses weight
Series bearing, in the case of not affecting installation, increase the bearing neck of semiaxis size (by
Φ 30 originally increases to Φ 40) load-carrying ability of back axle can be made again to improve 1.5-2 times.
Above-described embodiment only for technology design and the feature of the present invention are described, its object is to allow and is familiar with this
The personage of item technology will appreciate that present disclosure and implements according to this, can not limit this with this
The protection domain of invention.All equivalence changes made according to spirit of the invention or modification, all
Should contain within protection scope of the present invention.
