At present, in the increasingly extensive application in heavy motor vehicle field, particularly in the application in cross country car field, the maximum capacity that how to excavate the independent suspension drive axle becomes the emphasis of research along with the independent suspension drive axle.Use at present more independent suspension drive axle when the coupling independent suspension, the stage casing of bridge, main reduction gear and diff etc. are suspended on vehicle frame by being connected with axle housing, suspension two side drive wheel parts are connected with axle housing, and the drive wheel of both sides can swing up and down with respect to vehicle frame.But the connecting portion of the stage casing of above-mentioned bridge, main reduction gear and diff etc. and axle housing mostly adopts and casts out with the axle housing one, and this just makes the foundry technique of axle housing more complicated, and manufacture difficulty is large.The existing weak point of prior art that Here it is.
Summary of the invention
The technical problems to be solved in the utility model is exactly for the existing deficiency of prior art, and the housing assy of the simple heavy motor vehicle independent suspension drive axle of a kind of foundry technique is provided.
This programme is achieved by the following technical measures: this heavy motor vehicle independent suspension drive axle housing assy comprises axle housing and the semiaxis that arranges on it, described axle housing upper end is fixedly connected with two symmetrically arranged upper brackets, is provided with vehicle frame on upper bracket end face and suspension top link installation end face are installed; The lower end of axle housing is fixedly connected with two symmetrically arranged lower brackets, is provided with the suspension lower swing arm on lower bracket end face is installed; Be fixedly connected with protecting plate bracket between the end of two lower brackets, the lower surface of protecting plate bracket is fixedly connected with backplate, is provided with main reduction gear on the axle housing above backplate end face is installed.
Be provided with two groups of suspension lower swing arms on above-mentioned lower bracket end face is installed, power suffered in making lower bracket and suspension being connected is evenly shared by two groups of installation end faces, has reduced the suffered power of axle housing, thereby has reduced the manufacture difficulty of axle housing.
Above-mentioned semiaxis is symmetricly set in two sides of axle housing, and two semiaxis partly are connected with two side drive wheel respectively.
Above-mentioned upper bracket is captiveed joint with axle housing by tie bolt.
Above-mentioned lower bracket is captiveed joint with axle housing by tie bolt.
Above-mentioned protecting plate bracket is captiveed joint with lower bracket by tie bolt.
Above-mentioned backplate is captiveed joint with protecting plate bracket by tie bolt.
The beneficial effect of this programme can be learnt according to the narration to such scheme, in this heavy motor vehicle independent suspension drive axle housing assy, described axle housing upper end is fixedly connected with two symmetrically arranged upper brackets, is provided with vehicle frame on upper bracket end face and suspension top link installation end face are installed; The lower end of axle housing is fixedly connected with two symmetrically arranged lower brackets, is provided with the suspension lower swing arm on lower bracket end face is installed; Be fixedly connected with protecting plate bracket between the end of two lower brackets, the lower surface of protecting plate bracket is fixedly connected with backplate, is provided with main reduction gear on the axle housing above backplate end face is installed.After adopting this version, vehicle frame, suspension and main reduction gear etc. are connected with axle housing by split type attaching parts, under the prerequisite that guarantees Joint strenght, have simplified the foundry technique of axle housing like this, have reduced the manufacture difficulty of axle housing.This shows, the utility model compared with prior art has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
In figure, 1 installs end face for vehicle frame, and 2 are suspension top link installation end face, 3 is axle housing, and 4 is tie bolt, and 5 are suspension lower swing arm installation end face, 6 is semiaxis, and 7 is lower bracket, and 8 is tie bolt, 9 is backplate, 10 is tie bolt, and 11 is protecting plate bracket, and 12 are main reduction gear installation end face, 13 is tie bolt, and 14 is upper bracket.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
The housing assy of a kind of heavy motor vehicle independent suspension drive axle, as shown in Figure 1, it comprises axle housing 3 and the semiaxis 6 that arranges on it, semiaxis 6 is symmetricly set in two sides of axle housing 3.Described axle housing 3 upper ends are fixedly connected with two symmetrically arranged upper brackets 14 by tie bolt 13, be provided with vehicle frame on upper bracket 14 end face 1 and suspension top link installation end face 2 are installed; The lower end of axle housing 3 is fixedly connected with two symmetrically arranged lower brackets 7 by tie bolt 4, is provided with two groups of suspension lower swing arms on lower bracket 7 end face 5 is installed; Be fixedly connected with protecting plate bracket 11 by tie bolt 8 between the end of two lower brackets 7, the lower surface of protecting plate bracket 11 is fixedly connected with backplate 9 by tie bolt 10, is provided with main reduction gear on the axle housing 3 of backplate 9 tops end face 12 is installed.
During installation, axle housing 3 is connected by tie bolt 4 with lower bracket 7, backplate 9 is connected by tie bolt 10 with protecting plate bracket 11, and protecting plate bracket 11 and lower bracket 7 are linked together by tie bolt 8 and axle housing 3, form the integral body that intensity is higher, to guarantee to support main reduction gear; Axle housing 3 is installed end face 12 by main reduction gear to be connected with main reducing gear of drive axle, axle housing 3 is connected with upper bracket 14 by tie bolt 13, upper bracket 14 is installed end face 2 by the suspension top link and is connected with suspension, by vehicle frame, end face 1 is installed and is connected with vehicle frame, guarantee that stage casing, main reduction gear and the diff etc. of bridge are suspended on vehicle frame by being connected with axle housing 3; Two side drive wheel partly are connected with axle housing 3 by semiaxis 6, and the drive wheel of both sides can swing up and down with respect to vehicle frame, have reduced the use cost that the damage because of the live load on wheel and drive axle and part causes, and have improved reliability and service life.
