Abstract

The utility model belongs to the field of heavy vehicles, and discloses a steel plate spring side-matching double-shock absorber structure of a wide-body mining dump truck, which comprises a first upper bracket (2), a second upper bracket (3), a first shock absorber (4), a second shock absorber (5), a first lower bracket (6) and a second lower bracket (7); the first upper bracket (2) and the second upper bracket (3) are fixedly connected with the vehicle body; the first lower bracket (6) is fixed on a front lug rolling hole of the steel plate spring; one end of the first shock absorber (4) is hinged with the first lower bracket (6), and the other end of the first shock absorber is hinged with the first upper bracket (2); the second lower bracket (7) is fixed on a rear lug rolling hole of the steel plate spring; one end of the second shock absorber is hinged with the second lower support, and the other end of the second shock absorber is hinged with the second upper support. The technical scheme of the utility model has following advantage: the first shock absorber, the second shock absorber and the steel plate spring form a parallel structure, so that the vibration of the vehicle can be effectively attenuated, and the riding comfort of the members is improved.

Description

Leaf spring side-matched double-shock absorber structure of wide-body mining dump truck

Technical Field

The utility model belongs to the heavy vehicle field especially relates to a be applied to two bumper shock absorber structures on leaf spring suspension before wide mining dump truck.

Background

The wide-body mining dump truck has the advantages that the load-carrying mass is large, the road condition is poor, the jolting and heaving of the vehicle in the driving process are large, the single shock absorber is matched with the side face of the steel plate spring for improving the riding comfort, but the structural damping vibration capacity of the single shock absorber is poor, the improvement on the riding comfort is limited, and therefore the shock absorption structure capable of effectively damping the vibration of the vehicle and improving the riding comfort is required to be provided.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a two bumper shock absorber structures are matchd to mining dump truck leaf spring side of wide body to solve the poor technical problem of structure decay vibration ability of single bumper shock absorber.

In order to achieve the above object, the utility model discloses a two bumper shock absorber structures of wide mining dump truck leaf spring side matching's concrete technical scheme as follows:

a steel plate spring side-matched double-shock absorber structure of a wide-body mining dump truck comprises a first upper support 2, a second upper support 3, a first shock absorber 4, a second shock absorber 5, a first lower support 6 and a second lower support 7; the first upper bracket 2 and the second upper bracket 3 are both fixedly connected with a vehicle body;

the first lower bracket 6 is fixed on a front lug rolling hole of the leaf spring 1; one end of the first shock absorber 4 is hinged with the first lower bracket 6, and the other end of the first shock absorber is hinged with the first upper bracket 2;

the second lower bracket 7 is fixed on a rear lug rolling hole of the leaf spring 1; one end of the second shock absorber 5 is hinged with the second lower bracket 7, and the other end is hinged with the second upper bracket 3.

The first upper support 2, the second upper support 3, the first lower support 6 and the second lower support 7 are all of U-shaped plate structures, and connecting holes are formed in openings of the U-shaped plate structures.

The utility model discloses a two bumper shock absorber structures of wide body mining dump truck leaf spring side matching have following advantage: the first shock absorber, the second shock absorber and the steel plate spring form a parallel structure, so that the vibration of the vehicle can be effectively attenuated, and the riding comfort of the members is improved.

Drawings

Fig. 1 is the utility model discloses a two bumper shock absorbers structural schematic diagrams of mining dump truck leaf spring side matching of wide body.

Detailed Description

In order to understand the utility model discloses a purpose, structure and function better, combine the figure below, right the utility model relates to a mining dump truck leaf spring side of broad body matches two bumper shock absorber structures and does further detailed description.

As shown in fig. 1, the steel plate spring side-matching double-shock absorber structure of the wide-bodied mining dump truck of the present embodiment includes a first upper bracket 2, a second upper bracket 3, a first shock absorber 4, a second shock absorber 5, a first lower bracket 6, and a second lower bracket 7. The first upper support 2, the second upper support 3, the first lower support 6 and the second lower support 7 are all of U-shaped plate structures, and connecting holes are formed in the openings of the U-shaped plate structures. The first upper bracket 2 and the second upper bracket 3 are fixedly connected with a vehicle body.

The first lower bracket 6 is fixed on a front lug rolling hole of the leaf spring 1; one end of the first shock absorber 4 is hinged with the first lower bracket 6, and the other end of the first shock absorber is hinged with the first upper bracket 2.

Leaf spring 1, first bumper shock absorber 4, second bumper shock absorber 5 are parallelly connected structure, can effectively attenuate vehicle vibration, improve the travelling comfort that the member took, arrange compact reasonable, simple structure, good reliability.

Although the embodiments of the present invention have been described with reference to the accompanying drawings, it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the principles of the invention, and these changes and modifications should be construed as being included in the scope of the invention.
