【摘要】 基于车辆全轮转向的结构特点,在综合考虑转向半径、内外轮胎差速比等转向参数的影响下,建立了无驱动桥矿用重载车辆全轮转向机构理想转角和实际转角数学模型;通过2种模型的对比模拟仿真可知,实际转角模型比理想转角模型计算结果更真实准确,可以采用增大内侧或外侧的转向角来减小低速重载车辆的转向半径,可减小约13%,这为进一步无驱动桥矿用重载车辆全轮转向的结构优化提供了理论依据。更多还原

【Abstract】 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.更多还原
