离合器从动盘摩擦片,由于自然磨损、使用不当、起步过猛、调整不及时、打滑时间过长、车辆长期处于超负荷状态下工作等原因,造成钢盘铆钉孔磨旷。磨旷的铆钉孔,多呈椭圆,重铆新摩擦片时,再用原规格铆钉,显得十分松旷,必然保证不了质量,使用不会耐久。通常的修复办法有两种: 1.扩孔法在钢盘原孔的基础上,按磨损量最大的多数铆钉孔,选取相应的钻头和铆钉。进行全盘统一尺寸扩孔加工,重新铆摩擦片。实践证明,使用效果很好,同时也延长了钢盘的使用寿命。严禁加大孔和原孔同 Clutch driven disc friction plate, due to natural wear and tear, improper use, too much start-up, the adjustment is not timely, slipping for too long, the vehicle is under overload and long-term work and other reasons, resulting in steel rivet hole grinding. Grinding rivet holes, mostly oval, riveting new friction plate, and then the original specifications rivets, it is very loose Kuang, inevitable guarantee of quality, use will not be durable. The usual repair methods are two kinds: 1. Reaming method On the basis of the original hole in the steel plate, press the most rivet holes with the largest wear amount and select the corresponding drill bits and rivets. Uniform size reaming hole processing, re-riveting friction film. Practice has proved that the use of good results, but also extend the service life of steel. It is forbidden to increase the hole and the hole with the original
