后钢板限位销套不可漏装问:我单位用一辆东风 EQ140型汽油车改装成一辆柴油车。为提高其承载能力,改装时对左右后钢板弹簧各加了一片主钢板,但行驶不足一月时间,便发现左后钢板滑板磨损得不能再用了,不知何故,盼分析一下原因。好吗?(湖北张京)答:这种现象其他单位也出现过。例如有个单位在修车时,修理工将左边钢板后固定端支架处的限位销套弄丢了,于是就将该处的固定螺检死劲地紧固了一下,使后钢板端部与支架成了一整体。他不知道,二汽东风 EQ140的支架后端采用的是滑板结构,在汽车使用过程中地面的冲力会使钢板上下跳动,此时滑板端可自由伸缩,可是在制动时,车轮一抱死就会与路面形成拖带,车架上部重心因汽车惯性而上移,车轮发生跳动,后钢板弹簧后端与滑板处就处在连续冲击状态。若修理工过紧地拧紧支架螺枪、后钢板端部与滑板间运动受阻,两者之间磨损加剧,从而加速了滑板磨损。处理办法是更换新滑板,装上限位销套。注意:修理时切不可忘装钢板限位销套;要是不慎丢了,也必须弄个配件装上,不能瞎凑合。你单位那辆车极有可能是这个问题,你不妨查查。用粘结剂修水箱 After the steel limit pin sleeve can not be missed Q: I unit with a Dongfeng EQ140 gasoline car converted into a diesel car. In order to improve its carrying capacity, when the modification of each of the left and right rear leaf springs added a main plate, but driving less than a month’s time, we found that the left rear plate skate wear can not be reused, somehow, hope to analyze the reasons. Okay (Zhang Jing, Hubei) Answer: Other units of this phenomenon have also appeared. For example, when a unit repairs a car, the mechanic will lose the limit pin set at the rear end bracket of the left steel plate, and then fasten the fixing screw of that place tightly to make the end of the rear steel plate and the bracket Into a whole. He did not know, two steam Dongfeng EQ140 bracket rear end is skateboarding structure, the car’s use of the ground during the impulse will make the steel up and down beating, this time the free end of the scalable skateboarding, but braking, the wheels of a lock It will form a tow belt with the road, the center of gravity of the upper frame due to car inertia and move up, the wheel beats, the rear end of the leaf spring and skateboard at the continuous impact state. If the mechanic tightens the bracket gun tightly, the movement between the rear end of the steel plate and the sliding plate is blocked and the wear between the two increases, accelerating the sliding plate wear. Approach is to replace the new skateboards, install limit pin sets. Note: Do not forget to repair the steel limit pin set; if lost, you must also get a fitting, can not blindly make do. Your unit that car is most likely this problem, you may wish to check. Repair the tank with adhesive
