Reinforcement structure for rear wheel housing of vehicle

Abstract

A reinforcement structure for rear wheel housing of vehicle wherein a wheel housing inner panel and wheel housing cover of rear wheel housing are respectively coupled by a plurality of reinforcement members to further reduce vibration levels at intermediate and high speed booming domains, such that noise generated by resonance with exciting frequency input from road surface while a vehicle is running can be greatly decreased, the rear wheel housing including a wheel housing cover and a wheel housing inner panel protruded upwards to install a shock absorber of rear suspension system and wheels at left/right tip end parts of rear floor panel, the structure comprising: first and second reinforcement members for being respectively coupled up and down at front corner part formed by front and side surfaces of the wheel housing inner panel and extended to define closed sections upto a rear floor panel; a third reinforcement member extended fieldwise and coupled to a bottom surface of the wheel housing cover between first and second mounting parts formed toward external side of the vehicle body; and a fourth reinforcement member crosswise extended and coupled to a central portion of the first and second mounting parts.
