Abstract
The utility model relates to an auxiliary frame of a wheel loader. The auxiliary frame of the wheel loader disclosed by the utility model comprises four bottom plates welded together through cross beams and connecting plates. Holes used for fixing a rear axle are respectively formed in the bottom plates; a hinge pin hole for installing a hinge pin shaft is formed in each cross beam; the bottom part of each connecting plate is provided with check blocks. The auxiliary frame of the wheel loader is characterized in that a cut is formed in the middle of each connecting plate. According to the auxiliary frame of the wheel loader disclosed by the utility model, by adding reinforcing plates, increasing the stressed area of each cross beam, and the like, the strength and the stability of the auxiliary frame are integrally improved; the strength requirement of the auxiliary frame is satisfied, and the stress distribution is improved.
Description
Technical field
The utility model relates to a kind of subframe of loader.
Background technology
The working condition of wheel type loader is complicated and changeable, bear various force and moments, so the structural strength analysis of loader is very important in operation and walking process.
As shown in Figure 1, existing wheel type loader subframe is comprised of base plate, crossbeam, gusset piece, backing plate, block, 4 base plates are by crossbeam and gusset piece weld together, hole on base plate is used for fixedly back axle, hinged pin-and-hole on crossbeam is used for installing hinging pin shaft, by hinging pin shaft, subframe and rear vehicle frame is hinged.Having there is cracking in this loader in use subframe, is specially the weld cracking between backing plate and gusset piece, and cracking has also appearred in the weld seam between crossbeam and gusset piece; There is fracture in the bottom at the hinged pin-and-hole of crossbeam place.
Summary of the invention
The utility model aims to provide the wheel type loader subframe that a kind of strength and stability all improves.
Wheel type loader subframe described in the utility model, comprises 4 base plates by crossbeam and gusset piece weld together, and base plate is provided with the fixedly hole of back axle, and crossbeam is provided with the hinged pin-and-hole that hinging pin shaft is installed, and gusset piece bottom is provided with block; It is characterized in that being provided with otch in the middle of gusset piece.
Preferably, it also comprises the brace panel being connected with gusset piece, crossbeam and base plate respectively.
More preferably, the described maximum section radius in crossbeam bottom is 75mm.
Wheel type loader subframe described in the utility model is by increasing brace panel, increasing beam force area etc., and integral body has improved the strength and stability of subframe; Meet the requirement of strength of subframe, and improved the distribution of stress.

The specific embodiment
Embodiment mono-
As shown in Figures 3 and 4, the utility model wheel type loader subframe is comprised of base plate 1, crossbeam 2, gusset piece 3, block 6,4 base plates 1 are by crossbeam 2 and gusset piece 3 weld togethers, hole on base plate 1 is used for fixedly back axle, hinged pin-and-hole 5 on crossbeam 2 is for hinging pin shaft is installed, by hinging pin shaft, subframe and rear vehicle frame is hinged.
Wherein the utility model, by the synthetic part of gusset piece 3 and backing plate, has the otch that makes way for back axle in the middle of this part, can cancel the weld seam between gusset piece 3 and backing plate like this, thereby solve the weld cracking problem between gusset piece 3 and backing plate.
In addition increase brace panel 7, this brace panel 7 connects together gusset piece 3, crossbeam 2 and base plate 1, has improved on the whole the intensity of subframe.The oad of brace panel 7 is unsuitable excessive, otherwise subframe can interfere with rear vehicle frame while swinging to maximum angle.
Finally also add the cross-sectional area of the cross bearer 2 stressed maximums in bottom, the size 60mm in Fig. 1 is increased to 75mm.
