Abstract

The invention provides a decoupling film, a suspension assembly and a vehicle, and relates to the technical field of vehicle suspension. The decoupling film includes a decoupling film body, contact protrusions are formed on the upper end surface of the decoupling film body at intervals, and continuous annular sealing protrusions are formed on the lower end surface; by forming spaced contacts on the upper end surface of the decoupling film body The bulge makes the liquid flow between the two adjacent contact bulges to avoid vibration and noise, and a continuous annular sealing bulge is formed on the lower end surface to form a seal and block the flow of liquid. The suspension assembly of the present invention includes the decoupling film inside. The present invention also provides a vehicle, including the suspension assembly. The invention solves the problem that the existing suspension assembly generates cavitation noise and abnormal vibration noise during the operation of the vehicle, thereby affecting the ride comfort.

Description

technical field [0001] The invention relates to the technical field of vehicle suspension, and in particular to a decoupling membrane, a suspension assembly and a vehicle. Background technique [0002] As an auto part connecting the powertrain and the body, the suspension system plays the role of bearing, vibration isolation, and position limit. Among them, the hydraulic mount is generally composed of an outer skeleton, a main spring, a flow channel component, a liquid, and a bottom membrane. However, when the hydraulic mount of the existing vehicle encounters low-frequency and large-amplitude working conditions (such as road impact, speed bumps, etc.), the inertia of the powertrain will give a large impact to the hydraulic mount, thereby causing the hydraulic mount Generates cavitation noise. The specific process of cavitation noise is that when the vehicle passes through the speed bump or encounters a road impact, the main spring is rapidly stretched up during the jumpin...
