汽车的底盘出现异响是因为底盘上的橡胶衬套出现了老化的现象。底盘的橡胶衬套老化后会导致底盘上的很多部件旷量变大，这样会导致汽车经过颠簸路面时出现异响，解决这个问题只需要更换老化的底盘衬套就可以了。

The abnormal noise on the car chassis is due to the aging of the rubber lining on the chassis. After the rubber lining of the chassis ages, it can cause many components on the chassis to have increased play, which can cause abnormal noises when the car passes through bumpy roads. To solve this problem, simply replace the aged chassis lining.

汽车的底盘上是有悬架的，悬架有很多控制臂。各个控制臂的连接处都是有橡胶衬套的，并且控制臂与车身的连接处也是有橡胶衬套的。这些橡胶衬套可以提高汽车的舒适性。但是橡胶制品长时间使用会出现老化现象。如果橡胶衬套老化了，就会导致底盘异响，这样会影响汽车的行驶质感和操控性。

There is a suspension on the chassis of a car, which has many control arms. The connection of each control arm is equipped with rubber bushings, and the connection between the control arm and the vehicle body is also equipped with rubber bushings. These rubber bushings can improve the comfort of the car. However, rubber products may experience aging after prolonged use. If the rubber lining ages, it will cause abnormal chassis noise, which will affect the driving quality and handling of the car.

如果橡胶衬套老化了，需要及时更换。有些汽车控制臂上的橡胶衬套是无法单独拆卸更换的，这种汽车需要直接更换新的控制臂。在汽车上是有很多橡胶制品的，这些橡胶制品长时间使用都会出现老化现象，所以汽车上的橡胶制品是需要定期更换的。汽车上的橡胶部件有轮胎，密封胶条，皮带，底盘衬套等。

If the rubber lining ages, it needs to be replaced in a timely manner. Some cars have rubber bushings on their control arms that cannot be removed or replaced separately, and these cars require direct replacement with new control arms. There are many rubber products in cars, and these rubber products will age after long-term use, so rubber products in cars need to be replaced regularly. The rubber components on a car include tires, sealing strips, belts, chassis bushings, etc.

建议大家在平时用车时定期更换汽车上的橡胶制品，这样可以让汽车保持良好的车况。

It is recommended that everyone regularly replace the rubber products on the car when using it, which can keep the car in good condition.
