Disclosing a patent No. on January 7th, 2009 is that ZL200820101291.3, name are called the utility model patent of " a kind of loader subframe ", it comprises two brace tables that have the ridged girder of rotating shaft connecting portion, two auxiliary girders and four band fixed orifices, girder is connected with welding manner with auxiliary girder, form square subframe main body, four brace tables are welded on the two ends of auxiliary girder respectively, though the whole manufacturing cost of this loader subframe is lower, but integral body is comparatively thin, load-carrying capacity and impact resistance are relatively poor, use easily in than heavy-duty loader and damage.
The utility model content
The technical problems to be solved in the utility model provides a kind of subframe mechanism that is applied to forklift truck or wheel type loader, and load-carrying capacity and strong shock resistance are applicable to fork dress weight bigger forklift truck or heavy wheel type loader.
For achieving the above object, the technical solution of the utility model is: a kind of subframe mechanism that is applied to forklift truck or wheel type loader, comprise that two are roughly lambdoid girder, two girders be arranged in parallel, it is characterized in that: two girders respectively weld a stay bearing plate in the lower end of homonymy, the top of the lower end of two girder homonymies respectively is connected by a brace panel, the lower surface of two stay bearing plates is in the same plane, respectively be provided with a plurality of connecting through holes on the lower surface of two stay bearing plates, each girder comprises at least two blocks of chevron pointing plates that be arranged in parallel, weld mutually with two stay bearing plates two lower ends of every block of chevron pointing plate, the top that constitutes at least two blocks of chevron pointing plates that be arranged in parallel of each girder is connected by attaching parts, described attaching parts is provided with hinged through hole, and two hinged through holes of two girders are on the same axis.
Further improve, the top of two lower ends that constitutes at least two blocks of chevron pointing plates of each girder respectively is welded with positioning plate, and the upper surface of every positioning plate is in the same plane, and the upper surface of every positioning plate parallels with the lower surface of every stay bearing plate.When being conducive to increase the rear driving axle swing, the area of contact of subframe and back vehicle frame, the support strength of raising subframe.
Further improve, also be connected by at least one connecting panel between the brace panel on top, two girder lower ends of described connection and the stay bearing plate.Further strengthen bulk strength.
Further improve, two lower ends that constitute every block of chevron pointing plate of each girder are provided with knock hole, constitute between the knock hole on two lower ends of at least two blocks of chevron pointing plates of each girder to be connected by solid fix shaft.This structure had both strengthened the intensity of girder, and manufacturing process is improved in the mutual location between at least two blocks of chevron pointing plates of convenient each girder of formation again.
The utility model is because each girder comprises at least two blocks of chevron pointing plates that be arranged in parallel, weld mutually with two stay bearing plates two lower ends of every block of chevron pointing plate, the top that constitutes at least two blocks of chevron pointing plates that be arranged in parallel of each girder is connected by attaching parts, described attaching parts is provided with hinged through hole, two girders respectively weld a stay bearing plate in the lower end of homonymy simultaneously, the top of the lower end of two girder homonymies respectively is connected by a brace panel, this structure when alleviating subframe weight as far as possible, guarantee the intensity of girder, make subframe integral body have stronger load-carrying capacity and impact resistance, applicable to fork dress weight bigger forklift truck or heavy wheel type loader.
On the other hand, the utility model utilize two on the girder hinge hole and the back vehicle frame of forklift truck or wheel type loader be hinged, utilize the lower surface of two stay bearing plates to be connected across rear driving axle centre plane both sides, can improve the strained condition of forklift truck and wheel type loader rear driving axle and the strained condition of back vehicle frame greatly.
