Abstract
A hydro bush capable of dynamic characteristic tuning is disclosed. Hydro bush according to an embodiment of the present invention is formed between the inner pipe coupled through the first plunger, the outer pipe for accommodating the inner pipe and the inner pipe and the outer pipe is formed with a liquid chamber It includes an elastic body, an assembly hole of a predetermined size is formed in the lower end of the first plunger.
Description
The present invention relates to a hydro bush, and more particularly, to a hydro bush capable of tuning various dynamic characteristics.
In order to attenuate the vibration of the vehicle, it is generally installed between the vibration generating part such as the engine or the transmission of the vehicle and the vehicle body, and controls various vibrations and shocks to prevent the vibration and shock from being transmitted to the vehicle body. ) Is used. Among these bushes, the bushes formed by using the viscosity of the fluid and the characteristics of the rubber are referred to simply as a hydraulic sealed type bush.

Embodiments of the present invention to provide a hydro bush capable of dynamic characteristic tuning.
According to an aspect of the present invention, the inner pipe is coupled through the first plunger, the outer pipe for receiving the inner pipe therein, and the elastic body is formed between the inner pipe and the outer pipe is formed to include an elastic body The lower end of the first plunger may be provided with a hydro bush in which an assembling hole of a predetermined size is formed.
The apparatus may further include a second plunger fitted into the assembly hole of the first plunger.
The assembly hole may have a space formed therein, and the second plunger may include a head portion seated in the space, a pillar portion integrally formed with the head portion, and a bottom portion integrally formed with the pillar portion. can do.
In addition, the second plunger may be an elastic body.
On the other hand, the first plunger may be formed by coupling the front and rear members having assembly grooves formed at lower ends thereof, and the assembly grooves of the front and rear members may form the assembly holes.
The apparatus may further include a stopper coupled to at least one of front and rear surfaces of the inner pipe.
Embodiments of the present invention it is possible to tune the dynamic characteristics of the hydro bush by forming an assembling hole in the lower end of the main plunger, and adjusting the height of the auxiliary plunger fitted into the assembly hole.
Therefore, it is possible to implement a flexible and elastic hydro bush that can have a variety of properties.
