57什么是分时四驱?汽车在直线行驶时,四个车轮的转速是相同的,但在转弯时,尤其是急转弯时,四个车轮的转速可以说各不相同。外侧车轮比内侧车轮转速应快些,前轮比后轮转速应快些。在湿滑的草地、泥泞、沙漠行驶时,往往可以采用四轮驱动的方式,用分动器将四个车轮硬性连接,让四个车轮都按同样的转速进行驱动。因为这类路面的摩擦系数较低,转弯时前后车轮虽然会发生转向干涉,但是它们可以自由滑动(打滑),所以不
57 What is time-sharing, four-wheel drive? When a car drives in a straight line, the speeds of the four wheels are the same, but the speeds of the four wheels can be different when turning, especially when turning sharply. The outer wheel should be faster than the inner wheel, and the front wheel should be faster than the rear wheel. In slippery grass, muddy, desert driving, often can be used four-wheel drive mode, the transfer case will be four wheels rigidly connected, so that all four wheels are driven at the same speed. Because of the low coefficient of friction of such pavements, the front and rear wheels, while cornering, can interfere with steering but they can slide (slip) freely, so no
