Talk About the Rubber Metal Parts that Can Not Be Ignored on the Car

Rubber metal parts play an important role

During the driving of the car, many vibrations are generated due to the mechanical vibration of the engine and the transmission itself and the unevenness of the road surface. In order to suppress these vibrations and isolate them from the body and the cockpit, many rubber parts are installed in the car. Among the nearly 10,000 parts of a car, about 5% are rubber parts in various combinations, such as rubber suspension elements (commonly known as machine feet or claws) connecting the body to the engine and transmission, shock absorbers Upper seat (commonly known as top rubber), suspension link rubber bushing (commonly known as rubber sleeve), etc.

The main role of these custom rubber components in the suspension system is to make the suspension components move in a predetermined direction and transmit various forces on the one hand and to suppress various vibrations and isolate various noises on the other hand. In short, they are of great significance to the steering, braking, and driving stability of the vehicle, especially when driving on bumpy roads. For the harsh working conditions of these components, you can have an intuitive experience from the front suspension bench test video below.

Rubber aging is inevitable

For these rubber components, even without mechanical stress, the rubber itself will undergo a natural aging process, and large temperature fluctuations, sunlight radiation, ice, and snow, and salt corrosion are all factors that accelerate the aging of these components. For example, the damping performance of rubber bearings decreases over time, which can cause suspension noise when driving on bumpy roads, which can adversely affect vehicle travel. Therefore, it is very important to regularly check these rubber parts and replace them if necessary, so as to avoid the aging parts causing more serious damage to the other parts of the vehicle, resulting in high maintenance costs.

Custom Rubber Components

Pay attention to replacing rubber parts

The single wire seal manufacturer believes that there are certain things that cannot be ignored when replacing these rubber parts. For example, when installing the rubber bushing of the suspension connecting rod, the mounting bolts must be tightened when the suspension is in a compressed state to avoid bearing pretension and shorten the service life.

Due to the requirements of suspension structure design, some rubber parts are required to have different damping performance in different stress directions, for example, greater damping during braking than acceleration. In this case, the rubber parts are required to have a specific installation location. If they are not followed, the driving performance may deteriorate and the noise may increase after installation. For this reason, there will be some installation marks on the parts, we must learn to use the marks to install correctly.

In addition, we recommend that the rubber parts of the suspension system should be replaced in pairs, because the two parts on the left and right sides have the same mileage and are subject to the same stress, and their aging or damage is very close. Finally, do n’t forget: you must measure the wheel positioning parameters after replacing the suspension components. If you exceed the standard range, you must readjust it. Only in this way can you ensure that no repairs will occur, thereby improving customer satisfaction.
