【Abstract】Targeted at hydraulic mechanical transmission of tracked vehicle,it studied the load

characteristics from the power source and the load on the running,initially set the design load and applied

,

it to the prototype design. According to the experiment data and the problem of prototype stage it made


further analysis of load characteristics and changed ponents of hydraulic mechanical system. Af-

ter the follow-up tests,it showed that the design met the requirements of structural strength. The principle


of load distribution made
