目前生产的采用滑块式同步器,挂档脱不出的故障较多,特别是三、四档,有时光换齿环和滑块还不能解决问题,常常要改变基础件的位置才能解决。故障是因同步器齿环过松,挂档后,滑块单面跳出,爬上相关档位的同步器齿环上,造成不能退回,新换的也很松。我们就把一轴的四档齿压出2mm左右,垫实焊牢,使四档齿环端隙变小,滑块前后窜动间隙变小。这样做可以说是规范的,但从以排除故障为原 At present, the production of the use of slider-type synchronizer, hanging off more troubles, especially the third and fourth gear, and sometimes the ring and the slider can not solve the problem, often to change the location of the basic components can be resolved. Fault is due to the synchronizer ring gear is too loose, after hanging gear, the slider out of one side, climbing gear stalls on the synchronizer ring, resulting in can not be returned, the new change is also very loose. We put a shaft of the fourth gear out of about 2mm, pad solid welding, the fourth gear ring end gap becomes smaller, the gap before and after the slide play smaller. This can be said to be normative, but to eliminate the original fault
