Analysis on driving mode affected to steering performances of articulated rubber tyre vehicle

Based on an introduction on structure of articulated rubber tyre vehicle,the paper stated the features and application performances of the articulated rubber tyre vehicle when front axle driving mode or double axle driving mode was applied.A full load pivot steering mechanics model was established under different driving mode, virtual displacement principle was applied to have calculation formula of static steering resistance torque under different driving mode and a test was conducted on the stati C steering torque of the WC8E( B) articulated rubber tyre vehicle under different driving mode.The results showed that calculation value and test value were the seam basic ally and static steering resistance torque under double axle driving was higher than the relevant value of the front axle driving. The conclusion could provide the reference basis to the driving mode selection of other articulated rubber tyre vehicle and the design of the steering system.
