Abstract
The invention relates to an improved differential mechanism shell, and belongs to the field of accessories of an electric car. The improved differential mechanism shell solves the technical problems that in an existing differential mechanism shell, as axial holes perpendicularly extend out of a differential mechanism shell cover, the axial holes are prone to fracture, the service life is short, the working effect of a differential mechanism is wholly influenced, and the using requirement cannot be met. According to the technical scheme, the improved differential mechanism shell comprises a differential mechanism shell body and a differential mechanism shell cover fixedly connected with the differential mechanism shell body, axial holes are formed in the differential mechanism shell body and the differential mechanism shell cover, the differential mechanism shell cover comprises an end face used for being connected with the differential mechanism shell body, and transition sections are arranged between the end face and the axial holes. The improved differential mechanism shell has the advantages of being reasonable in structure, good in using effect and long in service life.
Description
Technical field
The present invention relates to the differential casing of a kind of improvement, belong to the accessory field of electric automobile.
Background technology
Automobile differential is the main part of drive axle.Its effect is exactly while transmitting power to both sides semiaxis, it is allowed to both sides semiaxis rotates with different rotating speeds, meets two sidecar wheels and makes Unequal distance traveling with the form of pure rolling as far as possible, reduces the friction of tire and ground.Differential casing is the important feature for protecting the internal each parts of differential mechanism to make its long-term safety effectively work.The housing of existing differential mechanism is generally divided into poor shell main body and difference cap two parts when design, fixing connection between two housings, the axis hole of gear shaft extends perpendicularly out poor cap, owing to differential mechanism operationally output torque is bigger, the differential casing axis hole causing current this structure is easily broken off, service life is short, affects the working effect of differential mechanism on the whole, it is impossible to meet user demand.Therefore, it should provide a kind of new technical scheme to solve 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, the differential casing of the improvement of long service life.
For reaching above-mentioned purpose, the technical solution used in the present invention is:
A kind of differential casing of improvement, including differing from shell body and fixing, with described poor shell body, the poor cap being connected, having axis hole on described poor shell body and difference cap, described poor cap includes, for the end face with difference shell body connection, being provided with changeover portion between described end face and axis hole.
The relevant content of technique scheme is explained as follows:
Described changeover portion is arc-shaped transition section.
Further technical scheme:
It is bolted between difference shell body and described poor cap.
Owing to technique scheme is used, the present invention compared with prior art has the advantage that
The differential casing of the improvement of the present invention, the changeover portion of arc it is provided with between connecting end surface and the axis hole of difference cap, adopt the structure the existing axis hole of replacement and connecting end surface structure connected vertically, be conducive to strengthening the intensity of axis hole, it is avoided in use to rupture, extend its service life, reduce use cost.
Accompanying drawing explanation
Fig. 1 is the embodiment of the present invention one structural representation.
Fig. 2 is Fig. 1 side view.
In the figures above: 1, differ from shell body, 2, difference cap, 3, axis hole, 4, end face, 5, changeover portion, 6, bolt.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
Embodiment one:
As illustrated in fig. 1 and 2, the differential casing of a kind of improvement of the present invention, the poor cap 2 being connected is fixed including difference shell body 1 and with described poor shell body 1, difference shell body 1 and difference cap 2 have the axis hole 3 for output shaft traverse, difference cap 2 includes, for the end face 4 with difference shell body connection, being provided with changeover portion 5 between end face 4 and axis hole 3.Described changeover portion 5 is arc-shaped transition section.
Preferably, as an embodiment, it is connected by bolt 6 between difference shell body 1 and described poor cap 2.
The differential casing of the improvement of the present invention, the changeover portion 5 of arc it is provided with between connecting end surface 4 and the axis hole 3 of difference cap 2, adopt the structure the existing axis hole of replacement and connecting end surface structure connected vertically, be conducive to strengthening the intensity of axis hole, it is avoided in use to rupture, extend its service life, reduce use cost.
Above-described embodiment only for technology design and the feature of the present invention are described, its object is to allow person skilled in the art will appreciate that present disclosure and to implement according to this, can not limit the scope of the invention with this.All equivalences made according to spirit of the invention change or modify, and all should be encompassed within protection scope of the present invention.
Claims (3)
1. the differential casing improved, including differing from shell body and fixing, with described poor shell body, the poor cap being connected, described poor shell body and difference cap have axis hole, it is characterized in that: described poor cap includes, for the end face with difference shell body connection, being provided with changeover portion between described end face and axis hole.
2. the differential casing of a kind of improvement according to claim 1, it is characterised in that: described changeover portion is arc-shaped transition section.
