Analysis on Full Wheel Steering Features of Mine Heavy Duty Non Driving Axle Vehicles

Based on the full wheel steering structure features of the vehicles,under the comprehensive considerations on the turning radius,the speed deferential rate of the inner and outer tires and other steering parameters,a rational turning angle and actual turning angle mathematical model was established for the full wheel steering mechanism of the mine heavy duty vehicles with non driving axle.The comparison simulations of the two models showed that the actual turning angle model would be more accurate than the calculation results of the rational turning angle model.The inner or outer turning angle increased could be applied to reduce the turning angle radius by 13% of the low speed heavy duty vehicle and could provide the theoretical basis for the structure further optimization.
