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 when an existing differential mechanism shell is used, the intensity is not enough, and the toughness is poor, 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 a kind of differential casing, 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., there is the defect of insufficient strength poor toughness in use, it is impossible to meet user demand in current differential casing.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 long service life.
For reaching above-mentioned purpose, the technical solution used in the present invention is:
A kind of differential casing, including left differential carrier and right differential carrier, left and right differential carrier is equipped with ring flange, described left and right flanges dish is equipped with bearing mounting structure, being connected by connector between ring flange on left and right differential carrier, on described left differential carrier and right differential carrier, the position of the connector on companion flange dish is provided with reinforcement.
Described left differential carrier and right differential carrier all include rustless steel top layer and rustless steel internal layer, are provided with enhancement Layer between described Stainless Steel top layer and rustless steel internal layer.
Described enhancement Layer is nickel-base alloy enhancement Layer.
Further technical scheme,
Described connector is bolt.
Described reinforcement be shaped as bending.
Owing to technique scheme is used, the present invention compared with prior art has the advantage that
The differential casing of the present invention, on housing, the position of the connector on companion flange dish is provided with reinforcement, nickel-base alloy enhancement Layer is set between rustless steel internal layer and the outer layer of differential casing, such structural design is conducive to strengthening the intensity of differential casing, 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.
In the figures above: 1, left differential carrier, 2, right differential carrier, 3, ring flange, 4, connector, 5, reinforcement, 6, enhancement Layer.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
Embodiment one:
As shown in Figure 1, one differential casing of the present invention, including left differential carrier 1 and right differential carrier 2, left and right differential carrier is equipped with ring flange 3, left and right flanges dish 3 is equipped with bearing mounting structure, being connected by connector 4 between ring flange on left and right differential carrier, in the present embodiment, connector 4 is bolt.On left differential carrier 1 and right differential carrier 2, the position of the connector 4 on companion flange dish is provided with reinforcement 5.
Left differential carrier 1 and right differential carrier 2 all include rustless steel top layer and rustless steel internal layer, are provided with enhancement Layer 6 between Stainless Steel top layer and rustless steel internal layer.
Preferably, as an embodiment, enhancement Layer 6 is nickel-base alloy enhancement Layer.
Preferably, as another embodiment, reinforcement 5 be shaped as bending.That designs reinforcement 5 is shaped as bending, it is possible to increase the intensity of differential casing further.
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.
