摘 要
推土機是土方工程機械的一種主要機械，按行走方式分為履帶式和輪胎式兩種.因為輪胎式推土機較少。本文主要講述履帶式推土機的結(jié)構(gòu)與工作原理。
推土機產(chǎn)品種的開發(fā)拓展，既要滿足不同工況條件的工作適應(yīng)性，又必須與基本型保持最大限度的零部件通用性（或稱互換性），這就為廣大用戶使用維修帶來極大的方便。為方便用戶購買配件，生產(chǎn)廠都保留了日本小松公司的零部件編號，只有改型中自行設(shè)計的零部件，才冠以自己廠家的編號。 履帶式推土機主要由發(fā)動機、傳動系統(tǒng)、工作裝置、電氣部分、駕駛室和機罩等組成。其中，機械及液壓傳動系統(tǒng)又包括液力變矩器、聯(lián)軸器總成、行星齒輪式動力換擋變速器、中央傳動、轉(zhuǎn)向離合器和轉(zhuǎn)向制動器、終傳動和行走系統(tǒng)等。本文將重點介紹上述傳動系統(tǒng)中的液力變矩器、行星齒輪式動力換擋變速器、轉(zhuǎn)向離合器和轉(zhuǎn)向制動器的結(jié)構(gòu)、工作原理及其液壓系統(tǒng)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 basic components to maintain the maximum commonality (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 hood components. Among them, mechanical and hydraulic drive system also includes torque converter, coupling assembly, planetary 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, planetary gear-type power-shift transmission, steering clutches and steering brakes structure, working principle and its hydraulic system and rule out the possibility of failure.
