Abstract
The utility model relates to a kind of differential casing of improvement, belongs to the accessory field of electric vehicle.The technical problems to be solved in the utility model is: current differential casing axis hole vertically stretches out poor cap, and axis hole easily ruptures, and working life is short, affects the working effect of differential mechanism on the whole, can not meet user demand.The technical solution adopted in the utility model is: a kind of differential casing of improvement, the poor cap comprising poor shell body and be fixedly connected with described poor shell body, described poor shell body and difference cap have axis hole, described poor cap comprises the end face for being connected with difference shell body, is provided with changeover portion between described end face and axis hole.The utility model has the advantages that: rational in infrastructure, using effect is good, long service life.
Description
Technical field
The utility model relates to a kind of differential casing of improvement, belongs to the accessory field of electric vehicle.
Background technique
Automobile differential is the main part of ransaxle.Its effect is exactly while the semiaxis transferring power of both sides, allows both sides semiaxis to rotate with different rotating speeds, meets two sidecar wheels and makes Unequal distance traveling with the form of pure rolling as far as possible, reduce the friction on tire and ground.Differential casing is the important feature its long-term safety effectively being worked for the protection of each parts in differential mechanism inside.The housing of existing differential mechanism is generally divided into poor shell main body and difference cap two-part when designing, be fixedly connected with between two housings, the axis hole of gear shaft vertically stretches out poor cap, due to differential mechanism, operationally output torque is larger, the differential casing axis hole of current this structure is caused easily to rupture, working life is short, affects the working effect of differential mechanism on the whole, can not meet user demand.Therefore, a kind of new technological 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 differential casing of the improvement of long service life.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of differential casing of improvement, the poor cap comprising poor shell body and be fixedly connected with described poor shell body, described poor shell body and difference cap have axis hole, and described poor cap comprises the end face for being connected with difference shell body, is provided with changeover portion between described end face and axis hole.
The related content of technique scheme is explained as follows:
Described changeover portion is arc-shaped transition section.
Further technological scheme:
Be bolted between difference shell body and described poor cap.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The differential casing of improvement of the present utility model, the changeover portion of arc is provided with between the connecting end surface and axis hole of difference cap, this kind of structure is adopted to replace existing axis hole and connecting end surface structure connected vertically, be conducive to the intensity strengthening axis hole, it is avoided in use to rupture, extend its working life, reduce user cost.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment one structural representation.
Fig. 2 is Fig. 1 side view.
In above accompanying drawing: 1, differ from shell body, 2, difference cap, 3, axis hole, 4, end face, 5, changeover portion, 6, bolt.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment one:
As illustrated in fig. 1 and 2, the differential casing of a kind of improvement of the utility model, the poor cap 2 comprising poor shell body 1 and be fixedly connected with described poor shell body 1, difference shell body 1 and difference cap 2 have the axis hole 3 passed for output shaft, difference cap 2 comprises the end face 4 for being connected with difference shell body, is 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, difference shell body 1 is connected by bolt 6 with between described poor cap 2.
The differential casing of improvement of the present utility model, the changeover portion 5 of arc is provided with between the connecting end surface 4 and axis hole 3 of difference cap 2, this kind of structure is adopted to replace existing axis hole and connecting end surface structure connected vertically, be conducive to the intensity strengthening axis hole, it is avoided in use to rupture, extend its working life, reduce user cost.
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.
