1. What is mounting: The mounting of a car engine is commonly known as "engine foot rubber", "engine rubber", "engine claw rubber", or "engine claw pad". It is a component that connects the vehicle body and the engine. It is mainly used to prevent the vibration of the engine from being transmitted to the vehicle body, reduce the impact of the ground on the powertrain, and play a role in support, limit, vibration isolation, and noise reduction.
2. Use of mounting: Three-point and four-point mounting systems are generally adopted in automobiles. This is because when the vibration is relatively large, if the number of mounting points increases and the vehicle body deforms, some mounting points may become misaligned, causing excessive force on the engine or mounting brackets and leading to damage.
The advantage of the three-point support is that no matter how the car bumps or jumps, it can always ensure that all support points are on the same plane, which greatly improves the force condition of the vehicle body. The front and rear mounts of the four-point mount are mainly used to prevent the torsion of the powertrain, and their torsional stiffness is better than that of the three-point mount.
The suspension is classified as a second-class vulnerable part. If one side of the suspension bracket is damaged, it will affect the engine vibration, driving and riding comfort, and pose a safety hazard during driving. In order not to be affected by the auxiliary parts of other components and not to harm the engine, it is necessary to replace three or four sets together as a complete set.
