Abstract
The utility model discloses an interaxial differential front shell, comprising a differential front shell body, wherein an arc-shaped groove extending into the differential front shell body along the axial direction of the differential front shell body is arranged at a matched and connected position, between the differential front shell body and a locking ring of a differential lock, on the differential front shell body. The interaxial differential front shell disclosed by the utility model has the advantages that by change of a tool withdrawal groove structure of the differential front shell and enlargement of inner steps, the reduction of the stress of the interaxial differential front shell is realized, and the faults of fracture of journals and fracture of spline root parts of the differential front shell of an automobile driving axle are effectively solved, so that the service lives of an automobile and an axle assembly are prolonged.
Description
Technical field
The utility model relates to automotive field, specifically a kind of novel interaxial differential front casing structure.
Background technique
This product mainly is the continuously Accident due to quality of fracture in use to occur in order to solve domestic STR vehicle bridge interaxial differential, shows that mainly the fracture of differential mechanism fore shell axle journal, spline root are disconnected, causes the axle assembly can't proper functioning, and vehicle can not normally move.
Summary of the invention
Deficiency at the prior art existence, technical problem to be solved in the utility model is, provide a kind of and reduce the concentrated stress of interaxial differential fore shell, effectively solve faults such as the fracture of automobile drive axle differential mechanism fore shell axle journal, the fracture of spline root, improve the interaxial differential fore shell in automobile and axle assembly working life.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of interaxial differential fore shell, comprise differential mechanism fore shell body, on the described differential mechanism fore shell body, be provided with the arc groove that axially extends in the differential mechanism fore shell body along differential mechanism fore shell body with the locking ring of differential lock place of being connected.
Above-mentioned interaxial differential fore shell arranges first step and the second step that is connected with each other in the described differential mechanism fore shell body, and described first step height is greater than half of second step height.
The advantage of the utility model interaxial differential fore shell is: change interaxial differential fore shell fillet into tool withdrawal groove structure (namely with the locking ring of differential lock cooperation place), simultaneously step in the interaxial differential fore shell is increased.Interaxial differential fore shell fillet changes the tool withdrawal groove structure into, simultaneously step in the interaxial differential fore shell is increased, and interaxial differential fore shell stress is reduced, thereby the market rate of fault is reduced.Through finite element analysis, its stress value is lower, can satisfy usage requirement preferably.Increase by changing differential mechanism fore shell tool withdrawal groove structure and interior step, to realize that interaxial differential fore shell stress reduces, efficiently solve the fault of the fracture of automobile drive axle differential mechanism fore shell axle journal, the fracture of spline root, thus the working life of improving automobile and axle assembly.
Description of drawings
Fig. 1 is the structural representation of the present interaxial differential fore shell of using always;
Fig. 2 is structural representation of the present utility model.
Embodiment
Reaching specific embodiment by reference to the accompanying drawings is described in further details the utility model;
As shown in Figure 1, 2, a kind of interaxial differential fore shell comprises differential mechanism fore shell body 1, on differential mechanism fore shell body 1, is provided with the arc groove 3 that axially extends in the differential mechanism fore shell body 1 along differential mechanism fore shell body 1 with the locking ring of differential lock place of being connected 2.First step 4 and the second step 5 that is connected with each other is set in differential mechanism fore shell body 1, and wherein, the height of first step 4 is greater than highly half of second step 5.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
