Cause of chassis loose

1、Chassis loose is from the chassis fault and abnormal sound

As the automobile is a product of mechanical structure, the chassis is also one of the most direct contact with the ground, but also participate in the vibration between the passenger and the road surface isolation and transformation of the structural part. Vehicle chassis parts are very much, their mutual coordination, directly related to the chassis of vibration absorption.

If the vehicle does not pay attention in the driving, there are knock against, impact or bottom phenomenon, will cause parts deformation or kuang, so the chassis will appear abnormal sound, bumpy and other loose phenomenon. In addition, some special cases, not caused by the chassis, such as the direction of the machine part, even the engine fender, fender and other easy to relax the part, will also bring abnormal sound and other loose feeling. This kind of chassis loose feeling is mostly caused by fault, can be improved by maintenance.

2、Shock absorbers brought by the loose feeling

When evaluating the shock absorption of a car, adjectives such as "clean and neat" and "less rebound and aftershocks" are often used. If the shock absorber bounces too little and the aftershock is too small, it will feel like a hard hit when it's too big: rebound aftershocks are hard to suppress for more flex and softer feeling.

If the main engine factory has a strong adjustment ability, it will take into account the appropriate flexibility required by the most frequently encountered road conditions. Here, there is a problem of "adjustment style". Experienced old drivers will feel the subtle differences when driving different cars on the same road. Some adjustments are a little softer, and rebound and aftershocks are often more.

3、Vehicle parts rubber bush performance aging

The rubber bushing on the chassis of a vehicle is an inconspicuous part, and they are often mounted on the chassis of the vehicle is more hidden. This component is also crucial to the ride experience. Automotive rubber bushing is used in the chassis moving parts and rigid body connection position, the chassis is the last shock of the isolation wall. And it is this small rubber part, is also very technical content, it is not only made of rubber, its internal, is full of oil! As the rubber parts squeeze out of shape, the oil has a complex motion loop inside to absorb the impact.
