The present invention relates to a hydraulic bushing, including a main spring and a cylindrical outer housing. The main spring comprising: a core shaft; a first rubber body arranged on an outer wall of the core shaft, wherein two liquid chambers diametrically opposite to and spaced from each other are formed on the first rubber body, each liquid chamber extending throughout the first rubber body along an axial direction thereof; and a sleeve mounted on an outer wall of the first rubber body, a groove being formed in an outer wall of the sleeve. The main spring is disposed inside an inner chamber of the outer housing, and a flow channel for connecting the two liquid chambers with each other is formed between the outer housing and the sleeve through the groove. The hydraulic bushing not only can assure stable operation of the vehicle in a straight running state, but also can reduce abrasion of a wheel and a rail in a curve running state.
