不少车龄较老的车，其中既有日系进口车，又有德系豪华车，更有自主品牌。从驾驶的过程中，发现这些车都有一个共同的特点，底盘松散！相信许多车主都深有体会，那为什么车底盘越开越松散？该怎么避免底盘松散？下面针对这些问题，带您一探究竟！
汽车开久了难免都会出现这样或那样的问题，毕竟汽车是一种消耗品，需要不断的保养与呵护。对于上了年纪的车型，最让车主头疼的莫过于各类震动和异响，除了发动机和变速箱带来的异响外，底盘往往成为最大的异响源。
底盘是最直接与地面接触的部分之一，同时也是参与乘坐着和路面之间震动隔绝与转化的结构部分。车辆底盘的零件非常多，其质量和相互之间的配合，直接关系到底盘对震动的吸收程度。通常来说，底盘松散的直观表现在于震动，同时也可能伴随着异响。
造成底盘松散的原因可以归结为三大方向：零件磨损松旷、橡胶老化和驾驶习惯。
多数底盘松散都来自于零件之间的磨损，底盘不像发动机那样，可以长期通过润滑油来减少磨损。虽说底盘各部件连接处都有不同程度的润滑油脂，但在风吹雨打后会变得干涩，渐渐失去功效。
其实如何保护底盘是很多朋友不注意的地方，都知道保护发动机保护变速箱，但是底盘的保护也不能忽视的，有条件的朋友平时多走一些路面平坦的地方，避免坑洼路面，尤其是井盖，大城市路上的井盖就是让底盘变散的一个罪魁祸首，再有就是减速带，减速带也是最伤底盘的一种障碍物了。
避免底盘松散的方法：
1.平时在驾驶汽车的时候，就要注意规范操作。
2.汽车要在一段时间中，做一定程度的保养。
3.停车时尽量选择平坦的道路，不要停在斜坡上，或者岔道上。
其实汽车的底盘松散并不是针对一些年龄老的车型，也是一些新上市的车型会遇到的问题。这里所说的底盘松散与上述所说的汽车的底盘松散是有区别的，内行人所述的“底盘松散”主要指汽车底盘的调教方面，有些新车型的悬架会偏硬一些，因而韧性比较好；而有些车型的悬架会比较软，开起来比较缓和。
每一款汽车，在研发的初期都会进行各类调教，而底盘调教的功底影响到汽车的性能。建议车主在买车的时候，最好是要亲身体验，才能找到适合自己的车型。
