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, Soil compaction 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.</p><p>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 its compact 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.</p><p>After more testing, this design get the following conclusions:</p><p>Chassis system can achieve a hydraulic pump motor differential walking two, to increase the adaptive capacity of the chassis. </p><p>The?design of the?chassis?mass of?2.5t, Compared with the current most of the chassis, Reached a?lightweight?design requirements</p><p>Variable speed?hydraulic?drive system?to achieve, At the same time to achieve high-speed braking and convert, Namely: working at low speed, transitions is high speed.
