有些驾驶员为了省油,常将汽车停在坡道上,利用汽车自由下滑溜坡启动。殊不知这样做得不偿失,既增加机件的磨损,也不利于行车安全。 驱动轮急剧磨损 溜坡开始时,由于挂空挡或离合器分离,机车呈自由滚动体下滑;当挂上挡,结合离合器时,气缸内气体压缩力变为阻力,通过传动系使驱动轮制动。但在汽车下滑惯性作用下,汽车 Some drivers in order to fuel-efficient, often cars parked on the ramp, use the car to start sliding downhill. As everyone knows do not worth the candle, not only increase the wear parts, is not conducive to traffic safety. When the traction wheel starts to slip, the locomotive is sliding down freely due to the neutral gear or the clutch is disengaged. When the gear is engaged and the clutch is engaged, the gas compression force in the cylinder becomes resistance and the driving wheel is braked through the drive train. But under the inertia of cars, cars
