制动系的主要功用,是使行驶中的拖拉机,按照驾驶员的要求及时实现减速或停车。使用制动系实现制动拖拉机在平路上行驶时,如果切断发动机动力(断开离合器或换入空档),发动机作用在驱动轮上的驱动扭矩消失,拖拉机在惯性作用下向前滑行。此时地面行驶阻力和传动,行走系的摩擦阻力使拖拉机逐渐减速,直至完全克服惯性力后,拖拉机才能停下来。从切断动力到拖拉机停下来,要行驶相当长的距离,靠这种方法停车是不行的。因此要设置制动系。
The main function of the braking system is to make the tractor in motion, and realize the deceleration or stop in time in accordance with the requirements of the driver. Braking with Braking System When driving the tractor on a flat road, if the engine power is cut off (the clutch is disconnected or neutral), the driving torque of the engine acting on the driving wheels disappears and the tractor slides forward by inertia. At this time, the driving resistance of the ground and the frictional resistance of the transmission system gradually decelerate the tractor until the tractor can stop after completely overcoming the inertial force. From cutting off power until the tractor stops, it takes a long way to go and stopping by this method will not work. Therefore, to set the brake system.
