Multi-piece combined inner core supported on automobile shock absorber

Abstract

The invention provides a multi-piece combined inner core supported on an automobile shock absorber. The multi-piece combined inner core comprises a partition plate and a vibration isolation part; thevibration isolation part comprises an upper vibration isolation block, an inner bonding layer and a lower vibration isolation block, wherein the partition plate is made of a metal material, and the upper vibration isolation block, the inner bonding layer and the lower vibration isolation block are all made of a polymer elastomer. The vibration isolation part of the multi-piece combined inner coreis different from an integrated inner core vibration isolation part which is widely used at present; different characteristics such as rigidity, density and elastic modulus of different materials areutilized, and different materials are combined to realize accurate adjustment for different demand designs; and the vibration isolation part is easier to design and manufacture, the product consistency is higher, and the performance is more stable.

Description

technical field [0001] The invention relates to the manufacture of automobile parts, in particular to a multi-piece combined inner core supported on an automobile shock absorber. Background technique [0002] The upper support of the shock absorber made of polyurethane elastomer has been used in the automobile chassis to connect the automobile suspension shock absorber and the automobile chassis and / or chassis parts, and is an important elastic element for attenuating automobile vibration. The vibration and noise generated by the contact between the car and the road surface are transmitted to the body through the wheels and the shock absorber. The vibration isolation elements supported on the shock absorber can weaken and isolate the vibration and noise as well as the vibration and noise generated by the shock absorber itself. The vibration isolation element also provides the possibility for the yaw movement of the shock absorber, and enables the whole vehicle to meet the mo...
