It is not very simple to replace the engine foot pad, because there are many things to be disassembled and the working hours are long. To replace the engine floor mat, the engine must be supported by a supporting device, and then the old floor mat is removed and replaced with a new floor mat. Then this process needs the cooperation of several people, so it is more troublesome to replace the foot pad of the machine. Machine pads are not expensive, but the labor cost of replacing machine pads is more expensive.
The engine pad is between the car body and the engine. The foot pad is used to buffer the vibration generated when the engine is running and prevent the vibration of the engine from being directly transmitted to the vehicle body. The machine mat is made of rubber, which will age and harden after a long time, so it can't play a buffering role after hardening, and the car will produce some vibration and jitter.
The gearbox also has organic foot pads to cushion some jitter generated during the operation of the gearbox.
Some high-end luxury models will use hydraulic foot pads, which are expensive and easy to leak oil. However, the foot pad of the hydraulic press can isolate the vibration of the engine more thoroughly and improve the quietness of the car. Some luxury cars even use electromagnetic pads. The hardness of the electromagnetic foot pad can be automatically adjusted according to different situations.
