Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing.

[0021] Such as figure 1 with figure 2 As shown, a shock absorber for a suspension system of a large excavator of the present invention is mainly composed of an upper cover plate 1, a support vulcanized body 2 and a protective plate vulcanized body 4; the protective plate vulcanized body 4 is provided with a support The base vulcanized body 2, the support vulcanized body 2 and the protective plate vulcanized body 4 are fixed together by connecting pieces; the upper cover plate 1 is installed above the support vulcanized body 2. The connecting piece is a hexagon socket head cap screw 6, and the hexagon socket cap screw 6 is locked by a conical pin 5.

[0022] In order to further prolong the service life of the present invention, a sleeve shaft 3 is provided between the protective plate vulcanization body 4 and the support vulcanization body 2 for position limiting. When th...

Abstract

The invention discloses a shock absorber for suspension systems of large excavators, which comprises a top cover plate (1), a support vulcanized body (2) and a protective plate vulcanized body (4); the support vulcanized body (2) is arranged on the protective plate vulcanized body (4), and the support vulcanized body (2) and the protective plate vulcanized body (4) are fixed together through a connecting part; the top cover plate (1) is mounted upon the support vulcanized body (2). The shock absorber adopts a conical shear type, most of rubber elastomers of the shock absorber are wrapped in a rigid shell, only a small part of the rubber elastomer II and the rubber elastomer III is exposed in the outside environment, consequently, the affection of solar radiation, oxygen aging, ozone aging and other factors on the elastomers of the shock absorber is little, the operating conditions of large excavators are met, the shock absorber plays the role of limiting sudden impact, and cannot be deformed severely to locally damage the structure in the rubber elastomers, and thereby the service life of the shock absorber is prolonged effectively.

Description

technical field [0001] The invention relates to a shock absorber, in particular to a shock absorber for a suspension system of a large excavator, belonging to the technical field of excavator shock absorption. Background technique [0002] With the leap-forward development of various basic large-scale projects in our country, the demand for large excavators has gradually increased, and the operating environment of large excavators is relatively harsh. The operation, and the workload is also strong, which puts forward higher requirements for the shock absorber of the excavator suspension system. The excavator is equipped with a suspension system to minimize the vibration transmitted from the power element to the support system. [0003] At present, the shock absorbers used in the suspension system of large excavators are usually of the upper and lower buckle type, the middle is positioned by a sleeve, and the outer flange, the middle sleeve and the elastic body are vulcanize...
