As a soft material, rubber parts are mainly used for the connection and protection of moving parts. The sealing and heat insulation of our doors and windows are all isolated by rubber sealing strips.
Door rubber bellows
Now more and more trucks have integrated functions such as electric windows, electric adjustable rearview mirrors, and even electric heating, which greatly improves the driving comfort of users and friends. But at the same time, in order to power these devices, there are many more wiring harnesses from the cab to the door. To protect these harnesses, the manufacturer has put a layer of rubber bellows on the outside of the harnesses. After a long time, the bellows is also prone to aging and rupture, and dust and rainwater may flow into the pipeline, resulting in equipment failure or short circuit.
Aging manifestation: failure or short circuit of door equipment.
Engine belt, air hose, cooling water pipe
Many air and water paths of our truck engines are connected by rubber hoses, such as the connecting hoses of the intercooler, the inlet and return pipes of the engine cooling water tank, etc., all of which are connected by rubber hoses.
If the hoses in these places are aged and broken, it will cause the vehicle engine to work abnormally. Therefore, we should pay attention to the aging of these parts during daily maintenance and prevent them in advance.
Also, the truck's engine belt is something to look out for. The belt is not only pulled by the tensioner, but also responsible for pulling other idlers, water pumps and other equipment, and the working temperature is also high. Moreover, the belt is outside the engine, and it will also be worn and polluted by foreign objects.
