Abstract
The utility model provides an automobile rear auxiliary frame, automobile rear auxiliary frame includes front -axle beam and differential mechanism support, the differential mechanism support adopts rectangular shape single chip architecture, and the welding is in on the front -axle beam the both sides of front -axle beam form the supporting structure of integral type. The utility model discloses automobile rear auxiliary frame differential mechanism support utilizes the differential mechanism support to make front -axle beam middle zone's local increase in thickness to the increase strength performance. This kind of structure makes strength character increase by 30%, and the thin zone of weakness territory of part is effectively strengthened, and it is more reasonable that weight distributes, and technology is more simple and convenient, and the risk that the part became invalid also obviously reduces.
Description
Technical field
The utility model relates to automotive field, particularly a kind of automobile rear sub-frame.
Background technology
Multi-link suspension is passenger-car chassis typical suspension form, and knuckle assembly and subframe couple together by the general 4-5 root connecting rod that adopts.After 4 wheel driven, pair is connected to stabilizer rod, Control arm, toe-in, diff and vehicle body, is component part important in chassis system.
Fig. 1 is the schematic diagram of traditional 4 wheel driven Rear secondary frame for vehicle, and as shown in Figure 1,4 wheel driven Rear secondary frame for vehicle 10 is welded by front-axle beam 11, side bar 13, the back rest 12 and a series of support 14, and front-axle beam 11 part mainly carries the loading force of toe-in and diff.
Fig. 2 is the assembling schematic diagram of conventional carrier support and front-axle beam.As shown in Figure 2, the both sides of support 14 are welded with front-axle beam 11 respectively.In fatigue test process, support 14 just ftractures lower than fatigue life after being subject to longitudinal force ringing, and formation of crack is in front-axle beam body and support junction.Fig. 3 is the assembling schematic diagram of conventional carrier support and sleeve.As shown in Figure 3, conventional carrier support 14 is welded by front and back two panels punching and welds with sleeve 15.Under the prerequisite meeting target weight, need the design adjusting part to reach and put forward performance-oriented object.
Utility model content
The technical problems to be solved in the utility model to be connected with front-axle beam easily to ftracture to overcome in prior art diff, and the defects such as performance is low, provide a kind of automobile rear sub-frame.
The utility model solves above-mentioned technical matters by following technical proposals: a kind of automobile rear sub-frame, its feature is, described automobile rear sub-frame comprises front-axle beam and diff support, described diff support adopts strip shape single chip architecture, be welded on described front-axle beam, form integrally supporting structure in the both sides of described front-axle beam.
Preferably, the two ends of described diff support respectively with sleeve weld.
Preferably, the shape of described diff support and the mating shapes of described front-axle beam are fitted.
Preferably, the centre portion width of described diff support is less than the width of both sides.
Positive progressive effect of the present utility model is:
The utility model automobile rear sub-frame diff support utilizes diff support that the local thickness of front-axle beam zone line is increased, thus improves strength character.This structure makes strength character increase by 30%, and part weakness zone is effectively strengthened, and weight distribution is more reasonable, and technique is easier, and the risk of part failure also obviously reduces.Described automobile rear sub-frame diff support has the advantages such as performance is strong, technique convenient, lightweight, also comparatively outstanding at the aspect of performance such as rigidity, intensity.
Accompanying drawing explanation
The above and other feature of the utility model, character and advantage are by more obvious by what become below in conjunction with the description of drawings and Examples, and Reference numeral identical in the accompanying drawings represents identical feature all the time, wherein:
Fig. 1 is the schematic diagram of traditional 4 wheel driven Rear secondary frame for vehicle.
Fig. 2 is the assembling schematic diagram of conventional carrier support and front-axle beam.
Fig. 3 is the assembling schematic diagram of conventional carrier support and sleeve.
Fig. 4 is the assembling schematic diagram of diff support and crossbeam in the utility model automobile rear sub-frame.
Fig. 5 is the assembling schematic diagram of diff support and sleeve in the utility model automobile rear sub-frame.
Detailed description of the invention
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, therefore the utility model is not by the restriction of following public specific embodiment.
Fig. 4 is the assembling schematic diagram of diff support and crossbeam in the utility model automobile rear sub-frame.Fig. 5 is the assembling schematic diagram of diff support and sleeve in the utility model automobile rear sub-frame.
As shown in Figure 4 and Figure 5, disclose a kind of automobile rear sub-frame in an embodiment of the present utility model, it comprises front-axle beam 20 and diff support 30.Diff support 30 herein adopts strip shape single chip architecture, is welded on front-axle beam 20, forms the supporting structure of integral type in the both sides of front-axle beam 20.This structure makes stress reach part material surrender, and fatigue life also reaches designing requirement.Diff support 30 adopts the design of monolithic, and its technique is simple and reach the requirement of light-weight design.
Further, the two ends of diff support 30 are welded with sleeve 40 respectively.The shape of diff support 30 and the mating shapes of front-axle beam 20 are fitted, and the centre portion width of diff support 30 is less than the width of both sides.
Describe according to said structure, the utility model automobile rear sub-frame utilizes diff support that the local thickness of front-axle beam zone line i.e. high stress areas is added, and effectively improves strength character.The strength character of described automobile rear sub-frame increases by 30%, and part weakness zone is effectively strengthened, and weight distribution is more reasonable, and technique is easier, and the risk of part failure also obviously reduces.
In sum, the utility model automobile rear sub-frame has the advantages such as performance is strong, technique convenient, lightweight, also comparatively outstanding at the aspect of performance such as rigidity, intensity.
Although the foregoing describe detailed description of the invention of the present utility model, it will be understood by those of skill in the art that these are only casehistorys, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection domain of the present utility model.
