Problems solved by technology

Therefore, under the condition that the size of the hydraulic bushing 2 is limited due to restrictions on vehicle assembly, the length of the flow path 52 cannot be ensured, and if the length of the flow path 52 is too long, the size of the liquid chamber 51 will be reduced and the hydraulic bushing will be reduced. 2 functionality is limited

Abstract

A hydro bush includes an outer pipe, an inner pipe, a rubber portion that is installed between the outer pipe and the inner pipe, and stoppers that are installed at both side ends. The hydro bush further includes a liquid chamber which is formed between the outer pipe and the rubber portion, and filled with a working fluid; and a flow path which is formed between the outer pipe and the rubber portion, and connected to the liquid chamber so as to guide the working fluid when the working fluid flows, in which the flow path includes a protruding portion which is formed to protrude inward. Accordingly, a flow distance of a working fluid flowing along the flow path may be increased without increasing a size of the hydro bush, thereby securing various dynamic characteristics.

Description

technical field [0001] The present invention relates to hydraulic bushings. Specifically, in order to adjust the dynamic characteristics of the hydraulic bushing, the hydraulic bushing has a structure that maximizes the length of the flow path and ensures a sufficient size of the liquid chamber. Background technique [0002] The suspension system of a general vehicle is an important device to enhance the ride feeling and driving stability. It mainly realizes the functions of making the vehicle body stably supported by the wheels and suppressing or rapidly reducing the vibration on the wheels. [0003] The suspension system uses a lower arm that is used to connect the wheel to the vehicle body and has a supporting function. The lower arm is equipped with geometric shape bushings to relieve vibration and impact from irregular surfaces, in order to improve the vibration transmission characteristics of the vehicle or The ride comfort and handling stability of the vehicle play a...
