Structure of roll-rod for subframe

Abstract

A structure of a roll-rod for a subframe filled with a hydro liquid therein, may include a bracket bar, an inner pipe including a cylindrical pipe and a supporting plate joined with the cylindrical pipe, an endplate joined to the cylindrical pipe, an outer pipe enclosing the inner pipe between the bracket bar and the endplate and including an extension part, where the supporting plate may be disposed with a gap in the extension part having a curved shape, an insulator forming a front liquid chamber and a rear liquid chamber with the supporting plate to receive the hydro-liquid therein, and a housing, wherein the supporting plate may move relative to the outer pipe such that the gap varies while the insulator is elastically transformed according to movement of the bracket bar and the endplate.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2011-0082661 filed on Aug. 19, 2011, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a structure of a roll-rod for a sub-frame, and more particularly, the present invention relates to a structure of a roll-rod for a sub-frame that can pass a load depending on the applied load. Instead, the flow state of the hydro liquid is variably controlled to more effectively absorb and suppress shocks, and at the same time reduce vibration and support the action of the power train by utilizing the flow of the hydro liquid filled therein. Background technique [0004] Monocoque bodies with small weight and high productivity are mainly used in vehicles instead of frame-type bodies. In a monocoque body which is a structure in which an additional frame is removed, a power ...

Problems solved by technology

[0011] However, the rear bushing in the related art using the elastic force of the material has the following problems: the dynamic ratio (the increase ratio of the dynamic load to the static load) is large, and the adjustment is difficult (in order to meet the design requirements)

[0012] In addition, elastic deformation and recovery of the rear bushing lead to fatigue of the material, and durability deteriorates in continuous use as a structure without an additional stopper (support against predetermined reference or greater elastic compression)
