Problems solved by technology

[0004] Practice has shown that the above methods all focus on the buffering and vibration reduction of the connection between the roller and the vehicle body, and do not fundamentally consider the vibration reduction of the roller. As the main bearing mechanism of the tracked vehicle, the severe impact vibration will inevitably affect the bearing Heavy wheel life and vehicle vibration

Abstract

The invention belongs to the technical field of vibration reduction and noise reduction for tracked vehicle wheels, and specifically relates to a mixed particle damper for tracked vehicle rollers, which includes a roller body and damping particles. A cavity for accommodating damping particles, a sealing cover for sealing the cavity is provided on the wheel body of the support roller, and a support is provided in the cavity. The rollers are filled with mixed damping particles, which combine the advantages of metal particles with wide frequency band, low impact force, low noise, light structure, high temperature and high pressure resistance, suitable for harsh environments and rubber particles with high elasticity, good wear resistance, and high tear resistance. The advantages of breaking strength and elongation.

Description

technical field [0001] The invention belongs to the technical field of vibration reduction and noise reduction for tracked vehicle wheels, and in particular relates to a mixed particle damper used for tracked vehicle rollers. Background technique [0002] Tracked vehicles can overcome certain terrain restrictions and are widely used in construction and machinery industries. However, its working conditions are generally under "non-road" conditions, and the harsh environment has a severe vibration impact on it. At the same time, severe vibration and noise have a serious impact on environmental pollution and driver comfort. Among them, the track roller is the main bearing structure of the crawler bulldozer, and the cushioning performance of the track roller directly affects the vehicle and the driver. [0003] Therefore, in order to ensure the reliability and comfort of tracked vehicles, the following methods are generally used for vibration reduction of track rollers: Chines...
