为了满足推土机在湿地和沼泽地作业要求,需降低推土机对地面的接地比压,防止推土机陷入湿地和沼泽,本文通过对基本型推土机与低比压推土机终传动装置比较,介绍低比压推土机终传动装置特点及主要承载件半轴的受力。1.低比压履带式推土机结构低比压履带式推土机,一般是以基本型推土机为基础,通过增加履带板宽度和履带长度,加大履带接地面积,降低接地比压。由于低比压履带式推土机履带板宽度大于普通型履带板,从而大
In order to meet the requirements of bulldozers in wetlands and marshes, it is necessary to reduce the earth pressure ratio of bulldozers to the ground and prevent the bulldozers from falling into the wetlands and swamps. This paper compares the final drive of the bulldozer with the low- Transmission characteristics and the main bearing half-shaft force. 1. Low-pressure crawler bulldozer structure Low-pressure crawler bulldozer, usually based on the basic bulldozers, by increasing the width of the track shoes and track length, increase track grounding area, lower ground pressure. As the low-pressure track-type tractor bulldozer track width wider than ordinary, and thus large
