Active geometry control suspension system

Abstract

An active geometric control suspension system may include an upper arm connected to a side above and between a rear wheel-sided knuckle and a subframe, and an assist link connected to the other side above and between the knuckle and the subframe, together with a node-changeable unit, wherein the node-changeable unit includes a housing formed at a portion of the subframe, a track-variable kit detachably coupled to brackets of the housing, cam-operating rails fixed to a side of the track-variable kit, a cam disposed on the cam-operating rails of the track-variable kit to be slidable up / down along the cam-operating rails, and a cam bolt connecting the cam with a vehicle body-sided connecting portion of the assist link.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application claims priority to Korean Patent Application No. 10-2011-0132821 filed in the Korean Intellectual Property Office on Dec. 12, 2011, the entire contents of which is incorporated herein for all purposes by this reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to an active geometry control suspension system (AGCS), and more particularly, to an active geometry control suspension system that makes it possible to reduce machining cost and A / S cost by using a track-variable kit that is separately manufactured.[0004]2. Description of Related Art[0005]An active geometry control suspension system that is generally applied to a rear suspension is a device that improves handling performance by improving cornering force of the rear wheel by changing the geometry of the rear suspension, when a vehicle rapidly turns.[0006]The active geometry control suspension system causes ov...

AI Technical Summary

Benefits of technology

The present invention provides an active geometry control suspension system that reduces machining and A / S costs by using a track-variable kit that functions like a cam-operating rail for each track. This kit can be easily applied to improve the performance of a vehicle and can be easily replaced when parts are replaced in A / S, reducing repair costs. The system allows for better tracking and toe change performance of a vehicle while using a housing.

Problems solved by technology

However, since the rail-mounting grooves 21 are formed at the housing 23 in the active geometry control suspension system described above, it is also necessary to change the tracks of the rail-mounting grooves 21 when performance tuning is performed while the tracks of the cam-operating rails 25 are changed in the development, it is required to manufacture a new housing 23 every time the tracks change, thereby causing a large amount of cost.
