Abstract

The invention discloses an auxiliary frame of a wheel loader. The auxiliary frame of the wheel loader comprises four base boards, and is characterized by further comprising two cross beams and two connecting plates, wherein each base board is connected with one end of one cross beam and one end of one connecting plate, attaching plates are arranged at two sides of a central hole in each cross beam respectively, reinforcing plates are arranged at the connecting positions between the base boards, the cross beams and the connecting plates, and a check block is arranged at the bottom of each base board. The auxiliary frame of the wheel loader has the advantages of being simple in structure, low in manufacturing cost, good in rigidity and strength, and the like.

Description

Wheel type loader subframe
Technical field
The present invention relates to a kind of wheel type loader subframe, belong to loader technical field.
Background technology
As shown in Figure 1, be the structural representation of existing wheel type loader subframe, by base plate 1, former crossbeam 9, former gusset piece 8, backing plate 7, formed, pasting board 6 is all posted in the both sides of the centre hole in the middle of former crossbeam 9.There is cracking in this loader in use subframe, cracking in various degree has all appearred in the weld seam between backing plate 7 and former gusset piece 8, between former crossbeam 9 and base plate 1, and cracking has appearred in the bottom at the hinged pin-and-hole of former crossbeam 9 place.
Summary of the invention
The technical problem to be solved in the present invention is: all good wheel type loader subframes of a kind of simple in structure, low cost of manufacture, Rigidity and strength are provided, solved loader in use subframe there is the problem of cracking.
In order to solve the problems of the technologies described above, technical scheme of the present invention has been to provide a kind of wheel type loader subframe, comprise 4 base plates, it is characterized in that, also comprise 2 crossbeams and 2 gusset pieces, the base plate described in each is connected with one end of 1 crossbeam, one end of 1 gusset piece, and on crossbeam, the both sides of centre hole are equipped with pasting board, junction between base plate, crossbeam, gusset piece is provided with brace panel, and the bottom of base plate is provided with block.
Preferably, the centre hole on described crossbeam is 15-40mm to the distance of crossbeam bottom.
Preferably, the centre of described gusset piece is provided with otch.
The present invention is simple in structure, low cost of manufacture, and brace panel is connected together crossbeam, gusset piece, base plate three, and integral body has improved the intensity of subframe; And gusset piece structure and profile are adjusted, and by original former backing plate and the synthetic gusset piece of former gusset piece, this gusset piece has the otch of stepping down to back axle in centre, the gusset piece of this structure is simple in structure, easily processing; Crossbeam has strengthened the distance between centre hole and bottom, and stressed sectional area is increased, and increases the intensity of this crossbeam.By to sum up improving, make the present invention there is good Rigidity and strength, can meet the operating needs of complete machine.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing wheel type loader subframe;
Fig. 2 is a kind of structural representation of wheel type loader subframe;
Fig. 3 is the A-A cutaway view of Fig. 2;
Fig. 4 is the structural representation of gusset piece.
In figure: 1 is base plate, 2 is brace panel, and 3 is crossbeam, and 4 is gusset piece, and 5 is block, and 6 is pasting board, and 7 is backing plate, and 8 is former gusset piece, and 9 is former crossbeam, and 10 is otch.
The specific embodiment
For the present invention is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
The present invention is a kind of wheel type loader subframe, as shown in Figure 2 and Figure 3, is a kind of structural representation of wheel type loader subframe.It comprises 3,2 gusset pieces 4 of 1,2 crossbeams of 4 base plates, brace panel 2, pasting board 6, four base plates 1 are by crossbeam 3 and gusset piece 4 weld togethers, be that each base plate 1 is connected with one end of 1 crossbeam 3, one end of 1 gusset piece 4, the hole on base plate 1 is for fixing loader rear axle.Brace panel 2 connects together crossbeam 3, gusset piece 4, base plate 1 three, and the junction between base plate 1, crossbeam 3, gusset piece 4 is welded with brace panel 2, and its integral body has improved the intensity of subframe.The bottom of base plate 1 is provided with block 5.
Centre hole on crossbeam 3 is for filling hinging pin shaft, by hinging pin shaft, subframe and rear vehicle frame is hinged, pasting board 6 is all posted in centre hole both sides, also strengthened the stressed sectional area of crossbeam 3 central hole bottoms simultaneously, soon the centre hole on crossbeam 3 increases to 15-40mm to the distance of crossbeam 3 bottoms, has improved the intensity of crossbeam 3.
As shown in Figure 4, be the structural representation of gusset piece 4.Gusset piece 4 structures and profile are adjusted, and by original backing plate 7 and the synthetic gusset piece 4 of former gusset piece 8, this gusset piece 4 has the otch 10 of stepping down to back axle (otch 10 for stepping down to rear driving axle, otherwise can interfere with back axle) in centre.The gusset piece 4 of this structure is not only simple in structure, easily processes, and has avoided the problem of weld cracking between backing plate 7 and former gusset piece 8, and improved the intensity of gusset piece 4.
The present invention is not only simple in structure, low cost of manufacture, and also this auxiliary frame structure has good Rigidity and strength, can meet the operating needs of complete machine.
