摘要
履带式底盘的结构特点和性能决定了它在农田耕作业中具有明显的优势,履带式底盘的接地比压相对较低。不会对翻耕过的土壤造成多次反复的碾压,而轮式底盘在整地和耙地作业时轮胎在翻耕过的土壤上反复碾压,造成对土壤的多次压实,不利于播种后种子的生长发育。因此,研究履带底盘的性能具有极其重要的意义。
本毕业设计的课题为履带式液压驱动底盘的设计,设计了一种后轮驱动行走底盘,底盘采用发动机与液压传动系统相结合实现动力匹配,底盘的液压系统实现了一泵驱动两马达差速行走,使其结构紧凑、操作灵活、安全可靠,能适应外负荷的剧烈变化,整机的性能得到了提高,能满足各种工况下的使用要求。在已知功率的情况下,整个设计参考农业机械的基本参数,选取了液压马达、液压泵等液压件。履带的结构同样参考了履带拖拉机的基本参数,设计了履带的结构和尺寸,使整个设计得到了优化。
经过比较试验,本设计得到以下结论:
,增加了底盘的自适应能力。
,与目前大部分底盘相比,达到了轻体的设计要求。
3..液压驱动系统能够实现无级变速,同时能够实现制动和高低速转换,即:工作时低速行驶,转场是高速行驶。灵活方便,易于操纵。

Abstract
Crawler chassis structure determines its characteristics and performance in the fields farming industry has a clear advantage. Crawler chassis ground pressure is relatively low. Tilling the soil will not cause too many repeated rolling. The wheeled chassis in the preparation and harrow tillage operations tires rolling over the soil again, paction caused by repeated is not conducive to the growth and development after sowing seeds, Therefore, the study tracked the performance of the chassis is extremely important.
The subject of this graduation project is tracked hydraulically driven chassis .Design a rear wheel drive, the chassis walk chassis engine and hydraulic transmission system to realize dynamic matching .The hydraulic system realizes the chassis a pump driven two motor differential walk, make pact structure, flexible operation, safe, reliable, and can adapt to the drastic change of load, the machine performance can satisfy the various working conditions of use requirement. In the case of a known power, the design references the basic parameters of agricultural machines, select a hydraulic motor, hydraulic pump, etc. The structure of the reference the same track basic parameters of the crawler tractor, design the structure and size of crawler, make whole design are optimized.
After more testing, this design get the following conclusions:
Chassis system can achieve a hydraulic pump motor
