Research about the arrangement of the lifted suspension under the minimum turning radius of tractors

This paper takes the tractor which was arranged many lifted suspension by the way of 6 × 2 as the object of study,and,analysis the arrangement of the lifted suspension under the minimum turning radius. The conclusions of research follow these:for playing the role of the front-outside turning angle "α_0max" fully and getting the minimum turning radius,we should set the second,the fifth and the sixth axles as the lifted suspensions,and the distance between the second and the third axles should be twice of "ΔL".The reasonable arrangement of lifted suspension provides possible conditions for matching one tractor with different trailers whose distance between each axle are different.
