摘要： A method for improving fatigue resistance performance of a locomotive rubber-metal pad with variable thickness improves the fatigue resistance performance of the rubber-metal pad and prevents rubber and metal from being torn during running by changing a structure of the rubber and the metal of the rubber-metal pad and adjusting a shape and position relationship between the rubber and the metal. The shape and the position relationship of the rubber metal is adjusted by adjusting thickness of a rubber layer between the rubber and the metal of the rubber-metal pad so that the rubber layer has variable thickness. The fatigue resistance performance of the rubber-metal pad is improved by adjusting the thickness of the rubber layer.

摘要： 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.

摘要： Disclosed is a hydraulic bushing and a rail vehicle. The hydraulic bushing comprises: a core shaft; a sleeve mounted on the core shaft, wherein a first rubber body is filled in a space formed between the core shaft and the sleeve, and a groove is provided on an outer surface of the sleeve; and an outer housing, which is mounted on the sleeve through press fit. Two liquid chambers for accommodating liquids are provided diametrically opposite to each other on the first rubber body, and the groove and the outer housing together define a flow channel, through which the two liquid chambers communicate with each other. Use of the hydraulic bushing on the rail vehicle not only can assure stable operation of the vehicle in a straight running state thereof, but also can reduce abrasion of a wheel and a rail in a curve running state.
