1离合器弹簧长期不调整或更换离合器弹簧长期受静压力作用,时间一长,就会塑性变形,其自由长度缩短,弹力减弱。离合器弹簧的弹力减弱,则离合器所能传递的力矩减小,发动机的功率就不能充分发挥,而造成拖拉机工作无力。
1 clutch spring long-term does not adjust or replace the clutch spring long-term by the role of static pressure, a long time, it will plastic deformation, shortening its free length, stretch weakened. Clutch spring weakened, then the torque can be reduced by the clutch, the engine’s power can not give full play, leaving the tractor ineffective.
