Problems solved by technology

If the damping effect of the damping system is not good, on the one hand, a large amount of vibration energy that should act on the road surface will be lost, and on the other hand, the vibration transmitted to the frame will make the operator's operating comfort of the roller worse.
A large number of tests have found that most of the existing domestic vibratory rollers have the problem of poor vibration damping effect

Embodiment Construction

[0036] like figure 1 , figure 2 As shown, the present invention includes two groups of rubber shock absorber groups symmetrically arranged on the left and right sides of the vibrating shaft 2 provided on the vibrating steel wheel 1 of the vibratory road roller. In the left and right shaft seats 4, the shaft seats 4 are fixedly installed in the vibrating steel wheel 1 through a support. The rubber shock absorber group includes a shock absorber support plate 5 installed vertically and coaxially on the shaft seat 4, and an upper vehicle that is located outside the shock absorber support plate 5 and is used to support and fix the upper frame of the vibratory roller. Frame support plate 6 and a plurality of rubber shock absorbers evenly arranged between the shock absorber support plate 5 and the upper frame support plate 6 along the circumferential direction, and the upper frame support plate 6 is arranged in parallel with the shock absorber support plate 5 . The rubber shock a...

Abstract

The invention discloses a novel vibration damping system for a vibratory road roller, which comprises two sets of rubber dampers arranged symmetrically on the left and right sides of the vibration axis; The upper frame support plate on the outside of the support plate and parallel to the shock absorber support plate and a plurality of rubber shock absorbers uniformly arranged between them along the circumferential direction; The shock absorber outer frame divided into two shock absorber chambers with the same structure by the shock absorber partition between the shock absorber support plates, two shock absorber cores respectively arranged in the inner middle of the two shock absorber chambers and A plurality of vibration-isolation rubbers are evenly and symmetrically arranged in the space between the shock absorber core and the inner wall of the shock absorber cavity. The invention is reasonable in design, reliable in performance and good in use effect. It changes the original working environment of the vibration-damping rubber from being sheared and stretched to a compressed state. While making full use of the performance of the rubber shock absorber, it also extends service life.

Description

technical field [0001] The invention belongs to the technical field of vibration reduction for vibratory road rollers, in particular to a novel vibration reduction system for vibratory road rollers. Background technique [0002] The vibratory roller is the leading model for road compaction, and its working objects have relatively high requirements on the quality of compaction operations. When working, the vibratory roller uses the vibration of the steel wheel to effectively compact the road surface. The steel wheel is connected to the frame through a vibration damping system, and the vibration will inevitably be transmitted to the upper frame. If the damping effect of the damping system is not good, on the one hand, a large amount of vibration energy that should act on the road surface will be lost, and on the other hand, the vibration transmitted to the frame will make the operator's operating comfort of the roller worse. A large number of tests have found that most of th...
