HYDRO BUSHING CAPABLE OF SUPPLYING AN IMPROVED NOISE VIBRATION HARNESS PERFORMANCE IN A HIGH FREQUENCY AREA AND TO SUPPLY IMPROVED STEERING STABILITY AND IMPROVED RIDING QUALITY AT A LOW FREQUENCY AREA
PURPOSE: A hydro bushing is provided to improve an NVH(Noise Vibration Harness) and riding quality in every frequency area by controlling the amount of fluids flowing through an inertia track.;CONSTITUTION: A hydro bushing comprises a first fluid chamber(130a), a second fluid chamber(130b), a first inertia track(140a), a second inertial track(140b), a main mass(150), a sub mass(160), and a control unit. The first fluid chamber and the second fluid chamber are formed between an outer(110) and an inner(120) and are filled with fluids. The first inertia track and the second inertia track are formed so that the fluids flow between the first fluid chamber and the second fluid chamber. The main mass wraps the inner and fills the space between the inner and the first inertia track. The sub mass fills the space between the first inertial track and the second inertial track. The control unit controls the opening of the second inertial track between the outer surface of the sub mass and the inner surface of the outer. The control unit disturbs or induces the flow of the fluid through the second inertia track according to the change in vibration frequency.;COPYRIGHT KIPO 2013;[Reference numerals] (130a) Fluid chamber(High pressure); (130b) Fluid chamber(Low pressure); (AA) Low frequency; (BB) High frequency
