摘要： A liquid composite spring for vehicles includes: a core shaft; an outer sleeve arranged on an upper portion of the core shaft, the upper portion of the core shaft being located inside the outer sleeve while the lower portion of the core shaft being located outside the outer sleeve; an upper liquid chamber formed in an upper portion of the outer sleeve, a lower end of the upper liquid chamber being connected to a top of the core shaft; and a lower liquid chamber formed in a lower portion of outer sleeve, the lower liquid chamber and the upper liquid chamber being connected with each other through a metal-rubber main spring. At least one flow channel body is provided in the metal-rubber main spring, so that liquid in the upper liquid chamber and liquid in the lower liquid chamber are communicated with each other through the flow channel body.

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.

摘要： A liquid composite spring and a method for adjusting stiffness and damping property of the liquid composite spring such that the liquid composite spring includes an outer sleeve; a core shaft arranged around an upper portion of the outer sleeve. An upper portion of the core shaft is located inside the outer sleeve, while a lower portion extends out of the outer sleeve; an upper liquid chamber formed in an upper space inside the outer sleeve and having a lower portion connected to a top end of the core shaft; and a lower liquid chamber formed in a lower space inside the outer sleeve and connected with the core shaft. The core shaft has a damping flow channel arranged therein, for communicating liquid in the upper liquid chamber with liquid in the lower liquid chamber. The liquid composite spring can provide vibration-reducing effect and change stiffness and damping effect.

摘要： A method for sealing a liquid composite spring, includes the steps of: placing a sleeve-shaped outer wall around an upper portion of a core shaft, and forming an upper liquid chamber and a lower liquid chamber inside the outer wall; and arranging a sealing member at a bottom of the outer wall to seal the lower liquid chamber, wherein the sealing member is made of flexible material. The liquid composite spring is provided with the rigid outer wall and the flexible sealing member. The volume and shape of the lower liquid chamber can be changed through the flexible sealing member, so that the chamber is formed as a flexible chamber.
