CN2234885Y - Platform chassis horizontal auxiliary supporting device for tipper - Google Patents

Abstract

The utility model relates to a bearing device of a vehicle, particularly a platform chassis horizontal auxiliary bearing device for a dump truck. Supporting frames are respectively arranged on the left side and the right side of the auxiliary bottom beam of the dump truck. A convex saw tooth is arranged on the supporting frames. A concave saw tooth is arranged on the corresponding position on the bottom of the body. When the body is in full load, two convex and concave saw teeth are engaged to form the auxiliary bearing device of the body of dump truck. A plurality of the auxiliary bearing device of the body of dump truck according to the length of the body of the dump truck to improve the bearing stiffness of the body andto lead the dump truck to have higher transverse stability and running speed when the dump truck runs on bad roads.

Description

The horizontal secondary support means of body of tipper carriage bottom girder

The utility model relates to a kind of means of vehicle support, belongs to the horizontal secondary support means of a kind of body of tipper carriage or rather.

In existing dumping truck, generally be that the compartment is bearing on the vehicle frame, there is not secondary support means at the front end of vehicle frame, descend back or in motoring condition, compartment only depends on Rea car body upset bearing set, plays compartment supporting and positioning action.Thereby when vehicle travels, slight shift is arranged about the compartment on bad road, increased the wearing and tearing of supporting member, and when condition of road surface is bad, can not move fast.

Task of the present utility model provides the horizontal secondary support means of a kind of body of tipper carriage bottom girder, and its purpose is: improve the lateral support rigidity of carriage of dump truck, make dumping car that higher lateral stability and speed of operation be arranged on bad road.

For achieving the above object, the technical scheme that the utility model is dealt with problems is: in the auxiliary bottom girder left and right sides of dumping car support is set respectively, at the top of support the convex sawtooth is set, the spill sawtooth is set, form the body of tipper carriage auxiliary device in corresponding position, bottom, compartment.The compartment at full load, the spill sawtooth of bottom, compartment and the convex engagement of support, shaggy tooth is a free-running fit when unloaded.One or more body of tipper carriage auxiliary devices can be set.

Compared with the prior art, the advantage that the utility model had is: can improve the lateral support rigidity of body of tipper carriage, improve the installing and locating precision in compartment, make dumping car that higher lateral stability and speed of operation be arranged on bad road.

Below in conjunction with accompanying drawing groundwork of the present utility model is described in further detail:

Fig. 1 is the horizontal secondary support means scheme drawing of body of tipper carriage bottom girder.

Fig. 2 is the A-A cutaway view of Fig. 1.

Wherein: 1-vehicle frame; 2-compartment; 3-auxiliary bottom girder; 4-support; 5-convex sawtooth; 6-spill sawtooth.

Concrete scheme of the present utility model is: at the auxiliary bottom girder of dumping car support [1] is set each side, at a top of the trellis convex sawtooth [5] is set, in corresponding position, bottom, compartment spill sawtooth [6] is set, when the compartment fell, the convex-concave engagement formed the self-discharging carriage secondary support means.When the vehicle at full load, the convex concave sawtooth contacts, and can guarantee the lateral support rigidity at full load compartment, reduces about the compartment and slightly moves.When zero load, leave the gap, to guarantee the fine contact of at full load shaggy tooth.As adorn when using the long vehicle railway carriage or compartment, the body of tipper carriage auxiliary devices that many cover supports and convex concave sawtooth form can be set, to satisfy the supporting hand hay cutter degree in compartment.By the secondary support means that the engagement of machicolated form sawtooth forms, improved the installing and locating precision of body of tipper carriage.

Claims (3)

1, the horizontal secondary support means of body of tipper carriage bottom girder, comprise vehicle frame [1], compartment [2], it is characterized in that: in auxiliary bottom girder [3] left and right sides of dumping car support [4] is set respectively, convex sawtooth [5] is set, form the body of tipper carriage auxiliary device at the top of support [4].

2, as the horizontal secondary support means of the said body of tipper carriage bottom girder of claim 1, it is characterized in that: the compartment at full load, the spill sawtooth of bottom, compartment and the convex engagement of support, convex and concave teeth is a free-running fit when unloaded.

3, as the horizontal secondary support means of the said body of tipper carriage bottom girder of claim 1, it is characterized in that: one or more body of tipper carriage auxiliary devices are set on a dumping car.
