Power assembly hydraulic suspension

Abstract

The invention relates to a power assembly hydraulic suspension device with a mechanical feedback control structure, which mainly comprises a ball-end connecting rod, a damping valve core (17) and a valve sleeve (11); one end of the ball-end connecting rod is connected with a connecting bolt (6) with the other end connected with the damping valve core (17); the damping valve core (17) can slide inthe valve sleeve (11); the damping of the working fluid in the suspension device is changed according to the real-time requirements of vibration isolation and noise reduction to be applicable to various operating conditions of the power assembly; thereby, the NVH performance of the entire vehicle is improved greatly; the riding comfort of the vehicle is improved obviously; the clients are ensuredto have brand-new driving and riding experiences.

Description

technical field [0001] The invention relates to a power assembly hydraulic mount for automobiles, in particular to a power assembly hydraulic mount with a mechanical feedback control structure. Background technique [0002] Because people have relatively mature manufacturing and processing technology for ordinary rubber mounts and ordinary rubber hydraulic mounts, and their prices are relatively low, they have been widely used, but ordinary rubber mounts and rubber hydraulic mounts are affected by rubber characteristics and Due to the limitations of its own structure, it is impossible to fundamentally eliminate the low-frequency resonance and high-frequency noise of the powertrain; they attenuate the vibration of the powertrain at high frequencies, and still cannot meet the consumer needs of customers who have higher and higher requirements for ride comfort. The design trend of lightweight body has aggravated the above phenomenon, resulting in more complaints from customers;...

[0002] Because people have relatively mature manufacturing and processing technology for ordinary rubber mounts and ordinary rubber hydraulic mounts, and their prices are relatively low, they have been widely used, but ordinary rubber mounts and rubber hydraulic mounts are affected by rubber characteristics and Due to the limitations of its own structure, it is impossible to fundamentally eliminate the low-frequency resonance and high-frequency noise of the powertrain; they attenuate the vibration of the powertrain at high frequencies, and still cannot meet the consumer needs of customers who have higher and higher requirements for ride comfort. The design trend of lightweight body has aggravated the above phenomenon, resulting in more complaints from customers; while semi-active magneto-rheological hydraulic mounts and active control hydraulic mounts have good vibration isolation and shock absorption performance, but most of them have complex structures. The cost is too high, it is still in the experimental testing stage, and it will take time to popularize and apply
