摘　　要：依据静力学平衡方程对4驱汽车前后轮正面跨越台阶、壕沟能力的理论分析和计算,得到了轮胎直径、附着系数、轴距、车重心距前后轴距离等参数都是影响越障的重要因素.目前丰田4驱SUV的8款汽车的这些参数有较好的跨越台阶、壕沟能力,但综合考虑汽车的安全性、舒适性,限制了这一性能的充分发挥,降低了它们的越障能力.According to the static balance equation, the theoretical analysis and calculation of the ability to cross the steps and trenches on the front and rear wheels of a 4-wheel drive are based on the theoretical analysis and calculation. It is understood that the parameters such as tire diameter, pay coefficient, wheelbase, center of gravity distance, and back axis distance are all important factors which affect crossing the barrier. At present, these parameters of the eight types of Toyota 4-drive SUV cars have a good ability to cross steps and trenches, but considering the safety and comfort of the car, the gap between the car from the ground, the close angle, and the angle of departure are reduced, which greatly affects their abilities to cross the barrier.
