拖拉机刹车时,必需依赖足够的附着力,使轮胎与地面摩擦产生反作用力,才能使拖拉机减速并停车。在附着力较小的滑路上强行刹车,虽然能制止车轮的滚动,但不能制止车轮在地面上的滑动。这样不但刹车距离很长,而且还会因操作不当使轮胎侧滑发生事故。所以在滑路上使用刹车必须注意以下事项: (1)严格调试刹车在滑路上行车前,应对主车和挂车的制动系认真检查调整,一方面要使两驱动轮的制动时间同步、效果一致,以免因刹偏而引起侧滑发生危险;另一方面要 Tractor brakes, must rely on sufficient adhesion, the friction between the tire and the ground reaction, can the tractor slow down and stop. Force less braking in the slippery road, although it can stop the wheel rolling, but can not stop the wheel slip on the ground. This will not only brake a long distance, but also due to improper operation of the tire side slip accident. Therefore, the use of brake on the slippery road must pay attention to the following: (1) strict debugging brake on the slippery road before the car and trailer to deal with the brake system to carefully check the adjustment, on the one hand to make the two drive wheel brake time synchronization, the effect Consistent, so as not to cause side slip slip caused by the danger; on the other hand to
