Description

TECHNICAL FIELD

[0002] Traditional suspension upper support assemblies usually adopt metal structures, such as cast iron or steel brackets, which have high strength but are heavy, and are not conducive to the lightweight demand of new energy vehicles. In addition, the existing suspension support structures often have stress concentration problems in the vibration transmission process, affecting durability and ride comfort.

Insufficient damping performance, the combination mode of the rubber damping part and the metal framework is single, which is easy to cause relative displacement and affect the damping effect; 3.
