摘要
推土机是土方工程机械的一种主要机械,。本文主要讲述履带式推土机的结构与工作原理。
推土机产品种的开发拓展,既要满足不同工况条件的工作适应性,又必须与基本型保持最大限度的零部件通用性(或称互换性),这就为广大用户使用维修带来极大的方便。为方便用户购买配件,生产厂都保留了日本小松公司的零部件编号,只有改型中自行设计的零部件,才冠以自己厂家的编号。履带式推土机主要由发动机、传动系统、工作装置、电气部分、驾驶室和机罩等组成。其中,机械及液压传动系统又包括液力变矩器、联轴器总成、行星齿轮式动力换挡变速器、中央传动、转向离合器和转向制动器、终传动和行走系统等。本文将重点介绍上述传动系统中的液力变矩器、行星齿轮式动力换挡变速器、转向离合器和转向制动器的结构、工作原理及其液压系统的故障及排除。

Abstract
Earthwork bulldozer machinery is one of the main machinery, by way of walking tracks and is divided into two types of rubber-tyred. Because less rubber-tyred bulldozers. This article focuses on the structure of crawler-type bulldozers and working principle. Bulldozers to expand product development of species, it is necessary to meet the needs of different working conditions of the work of adaptation, but also with the ponents to maintain the monality (or interchangeability), which for the majority of users will have an extremely maintenance Great convenience. To facilitate the purchase of spare parts, production facilities have retained parts of Komatsu, Japan ID, only the modified parts of their own design, only the number of manufacturers known as their own. Tracked by bulldozer engine, drive system, the working device, electrical parts, such as driver's cab and ponents. Among them, mechanical and hydraulic drive system also includes torque converter, coupling assembly, ary gear-type power-shift transmission, the central transmission, steering clutches and steering brakes, final drive and running systems. This article focuses on the above-mentioned transmission system in the torque converter, ary gear-type power-shift transmission, steering clutches and steering brakes structure, working principle and its hydraulic system and rule out the possibility of failure.
