Engine mount rubber pads Description

 

The engine mount rubber pad is an important part of the connection between the engine and the body of the automobile, and its main functions and related information are as follows:

 

Function

1

Fix the engine: Firmly fix the engine to the frame to ensure that the engine can run stably in various working conditions.

2

Shock absorption and noise reduction: Through the elasticity and softness of rubber, it absorbs and disperses the vibration and impact force generated by the engine when it is working, reduces the vibration and noise transmitted to the body, and improves ride comfort.

3

Reduced friction and wear: Creates a cushioning layer between the engine and chassis, reducing direct contact and collisions, and reducing component damage caused by friction and wear.

4

Thermal insulation and fire prevention: Rubber materials have certain thermal insulation properties, which can block the conduction and radiation of heat energy, prevent the high temperature generated by the engine from being transmitted to the chassis, reduce the chassis temperature, and reduce fuel loss. At the same time, the rubber material also has relatively high fire performance, which can prevent fire under abnormal engine conditions to a certain extent.

 

Performance metrics Unit Typical value
Hardness Shore A 30 to 100
Tear strength kg/cm² 50 to 300
Elongation % 100 to 1000
Heat resistance °C 100 to 150
Cold resistance °C -30 to -70

 

Material

Engine mount rubber pads typically use the following rubber materials:

1

Natural Rubber (NR): It has good elasticity and fatigue resistance, and is suitable for general shock absorption needs.

2

Styrene-butadiene rubber (SBR): low cost, stable performance, often mixed with NR to reduce costs.

3

Butadiene rubber (BR): It has excellent abrasion resistance and elasticity, and is suitable for high-load shock absorption needs.

4

Nitrile rubber (NBR): It has good oil resistance and heat resistance, and is suitable for environments with a lot of oil around the engine.

5

Neoprene (CR): It has good weather resistance and aging resistance, and is suitable for outdoor environments.

6

Ethylene propylene diene monomer (EPDM): It has good heat resistance and ozone resistance, and is suitable for high-temperature environments.

Apply

1

Engine mounting: It is used for the connection between the engine and the body, effectively absorbs the vibration of the engine, avoids the transmission of vibration to the body, and improves the comfort of the car.

2

Transmission system: It is used for the central bearing of the transmission shaft and other parts to reduce the vibration of the transmission shaft and ensure the smooth operation of the transmission system.

3

Chassis mounting: It is used for the connection between the chassis and the body to reduce the vibration from the chassis and improve the driving stability of the vehicle.

 

Maintenance & Replacement

Inspection cycle: It is recommended to check the condition of the engine mount rubber pads every 6 to 80,000 km.

Replacement conditions: If it is found that the rubber pad is aging, cracking, deformed, or separated from the metal joint, it should be replaced in time to avoid aggravated engine vibration and affect driving safety.
