Abstract
The utility model discloses a loader auxiliary frame, which comprises two ridged main girders with rotation shaft connecting portions, two auxiliary girders and four supporting disks with fixing holes, wherein the main girders and the auxiliary girders are connected in a welding type to form a square auxiliary vehicle frame main body, and the four supporting disks are respectively welded on both ends of the auxiliary girders. The loader auxiliary frame segments an auxiliary vehicle frame which is integrally casted into various same spare parts to be respectively manufactured, and then adopts a welding type to form a complete auxiliary vehicle frame to save the investment of moulds. When same-type loaders with various different types or specifications are produced, partial moulds only needs to be modified, and the adaptability of the manufacturing technique of the auxiliary vehicle frame of the loader is improved.
Description
Technical field
The utility model relates to the automobile bearing system, relates to a kind of loader subframe particularly.
Background technology
The loader drive axle is made up of propons and back axle, because loader needs big tractive force, bridge is drive axle before and after the therefore modern wheel type loader.Propons directly is fixed on the front vehicle frame, and back axle is a swing axle, links to each other with the back vehicle frame by subframe, and subframe and back axle can rotate by the rotating shaft connecting portion, and subframe is fixed on the vehicle frame.Existing loader subframe comprises two ridged girders that have the rotating shaft connecting portion, and two auxiliary girders and four brace tables adopt inblock cast to form, and are very big to the input of casting mould.When the automobile of the same type of multiple different model of development or specification, need carry out integral body transformation to mould, loader subframe production technology bad adaptability, the cost of casting mould has high input.
The utility model content
The purpose of this utility model is to provide a kind of loader subframe that is formed with welding manner by multiple metal plate punching spare and Casting Parts, to solve the above-mentioned problems in the prior art, loader subframe in the utility model is divided into multiple identical parts with the cast-in-block subframe and makes respectively, then adopt welding manner to form a complete subframe, to save input to mould.When the loader of the same type of multiple different model of development or specification, only need transform part mould wherein, improved the comformability of loader subframe production technology.
The technical scheme that the utility model provides is as follows:
A kind of loader subframe, comprise that two have the ridged girder of rotating shaft connecting portion, two auxiliary girders and four brace tables with two fixed orifices, it is characterized in that: girder is connected with welding manner with auxiliary girder, forms square subframe main body, and four brace tables are welded on the two ends of auxiliary girder respectively.
Described rotating shaft connecting portion is provided with through hole.
The loader subframe also can be provided with four brace panels, and brace panel is welded on four interior angle places of subframe main body respectively, and brace panel can further firm loader subframe.
Described subframe also can comprise four axle collars, and the axle collar is welded on the both sides of rotating shaft connecting portion.
It is prominent that the both side ends of girder can also be provided with card respectively, and card is prominent can to make the location of girder, auxiliary girder and brace table more accurate, and the prominent face of weld that has also increased girder and brace table of card can make whole loader subframe more firm, and load carrying ability increases.
Brace table can also be provided with groove.Groove can be for one or more, to reduce the iron and steel use amount of subframe.
Two girders, two auxiliary girders, four brace panels and four axle collars all are sheet metal component, and four is Casting Parts with the brace table of two fixed orifices respectively.
Two girders, two auxiliary girders can use same mould-manufacturing respectively, reduce subframe produce in to the input of mould; The shape and size of four brace tables also can be set to left-right symmetric, further reduce the input to mould.Four brace panels, four axle collars also can use same mould-manufacturing respectively, reduce subframe produce in to the input of mould.Use the above-mentioned parts of same mould-manufacturing can guarantee to weld symmetry before and after the loader subframe of formation respectively, make subframe when rotating, keep balance.
Because the utility model is divided into multiple identical parts with cast-in-block subframe in the prior art and makes respectively, then adopt welding manner to form a complete subframe, saving is to the input of mould, when the multiple different model of development loader of the same type, only need transform, improve the comformability of loader subframe production technology part mould wherein.The utility model uses same mould-manufacturing respectively with two girders, two auxiliary girders, four brace panels and four axle collars, and the shape and size of four brace tables also can be set to left-right symmetric, with the input of further minimizing to mould.Subframe of the present utility model also can be provided with groove on brace table, reduce iron and steel raw material, and alleviates the quality of subframe.
Description of drawings
Fig. 1 is the loader subframe perspective view of the utility model embodiment 1;
Fig. 2 is the loader subframe perspective view of the utility model embodiment 1.
The specific embodiment
Shown in seeing figures.1.and.2.A kind of loader subframe is made up of two ridged girders that through hole is set in the center 1, two auxiliary girders 2, four brace panels 3 and four brace tables 4 with two fixed orifices.
Two girders 1 and two auxiliary girder 2 welding form square subframe main body, and four brace panels 3 are welded on the interior angle place of subframe main body respectively, and four brace tables 4 are welded on the two ends of auxiliary girder 2 respectively.
The spine of girder 1 is circular-arc.
Four axle collars 5 are fixed on the both sides of through hole with welding manner.
The both side ends of girder is provided with card prominent 6 respectively.
Four brace tables also are provided with two grooves 7 respectively.
Above-mentioned only is a specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
