Abstract

The utility model discloses an auxiliary frame for a dump truck. The dump truck comprises a left longitudinal beam and a right longitudinal beam in parallel; a plurality of crossbeams are arranged between the left longitudinal beam and the right longitudinal beam, and are perpendicular to the left longitudinal beam and the right longitudinal beam; and torsion-resistant beams are also positioned between the left longitudinal beam and the right longitudinal beam. According to the utility model, as the torsion-resistant beams installed between the crossbeams and the longitudinal beams adopt a cross structure, the torsional strength of the auxiliary frame and the stability of the entire dump truck are improved. As a structure of square shaped tubes is adopted for assembling the whole auxiliary frame, the manufacturing procedures are simplified, the manufacturing cost is reduced, the production efficiency is improved, and the strength of the longitudinal beams and the crossbeams is improved and well guaranteed.

Description

The dumping car subframe
Technical field
The utility model discloses a kind of dumping car subframe, be specifically related to improvement dumping car subframe structure.
Background technology
Before the utility model is made, existing dumping car subframe mainly is to be formed by the longitudinal and cross beam Combination Welding, and longeron, crossbeam normally are welded after the channel-section steel open side installs shrouding additional, in installing the welding process of shrouding additional, channel-section steel certainly will the internal stress of channel-section steel be exerted an influence, thereby make bulk strength descend, and welding technological properties is had relatively high expectations, will certainly increase productive costs like this, reduce production efficiency.
Summary of the invention
The utility model provides a kind of dumping car subframe at the deficiency of prior art, and this subframe is simple in structure, has reduced manufacturing procedure, has reduced productive costs.
Below introduce structure of the present utility model in detail, a kind of dumping car subframe comprises left longeron and right vertical beam parallel to each other, and a plurality of crossbeams vertical with them are set between left longeron and the right vertical beam, between described left longeron and the right vertical beam antitorque beam is set also.
Optimally, the material of described left longeron, right vertical beam, crossbeam and antitorque beam is the moulding square tube.
Optimally, described antitorque beam is " ten " word structure.
Optimally, " ten " word structure of described antitorque beam is orthogonal and a short beam and a long beam of being fixed together.
Optimally, described antitorque beam all is provided with brace panel in the top and bottom of " ten " word structure junction.
Optimally, described antitorque beam is provided with one or more between left longeron and right vertical beam.
Optimally, described left longeron and right vertical beam inboard are provided for avoiding the hole of welding stress.
The utility model has the advantages that the antitorque beam that between crossbeam and longeron, is provided with employing " ten " word structure, improved the stability of the torsional strength and the car load of subframe.Whole subframe has reduced manufacturing procedure after adopting the moulding rhs-structure, has reduced productive costs, has improved production efficiency, and its longeron, beam strength improve, and have well guaranteed the intensity of longitudinal and cross beam, thereby has guaranteed the intensity of whole subframe.Select suitable dimensions by optimal design, can saving in material, cost-cutting.
Description of drawings
Figure of description 1 is a structural representation of the present utility model;
Figure of description 2 is the front view of the utility model longeron;
Figure of description 3 is the structural representation of the antitorque beam of the utility model.
The specific embodiment
Below in conjunction with Figure of description utility model is done further to disclose.
Embodiment 1:
See also Figure of description 1, a kind of dumping car subframe comprises left longeron 1a and right vertical beam 1b parallel to each other, and a plurality of crossbeams 2 vertical with them are set between left longeron 1a and the right vertical beam 1b, and antitorque beam 3 also is set between described left longeron and the right vertical beam.Antitorque beam can be provided with one or more between left longeron and right vertical beam, the utility model only end between left longeron 1a and right vertical beam 1b is provided with an antitorque beam 3.One end of subframe adopts antitorque beam to improve the torsional strength of subframe, has prolonged service life.The material of left side longeron, right vertical beam, crossbeam and antitorque beam is a 16Mn moulding square tube.The material of those parts is the moulding square tube, has improved the intensity and the production efficiency of subframe.
See also Figure of description 2, left longeron 1a and right vertical beam 1b inboard are provided for avoiding the hole 4 of welding stress.Stress concentration when avoiding welding is convenient to and being connected of chassis; At longeron front and back end welding shrouding, improve the intensity of longeron.
See also Figure of description 3, antitorque beam 3 is " ten " word structures.It comprises a short beam 31 and a long beam 32 of orthogonal and weld together.Antitorque beam adopts " ten " word structure, has improved the stability of the torsional strength and the car load of subframe.
Antitorque beam 3 all welds brace panel 33 in the top and bottom of " ten " word structure junction.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
