摘要： Disclosed herewith a hydraulic composite bushing (100, 200) and a sealing method for same. The hydraulic composite bushing (100, 200) comprises: a core shaft (10, 210), with a continuously spiral fluid channel groove (11, 211) formed on an outer surface thereof; a rubber member (20, 220), arranged around the core shaft (10, 210), and having two recesses formed radially outside of the fluid channel groove (11, 211) and radially opposite to each other; a support ring (30, 230) arranged around the rubber member (20, 220), covering the fluid channel groove (11, 211) to form hydraulic chambers (40, 240) for accommodating hydraulic fluid; an outer cover (50, 250) pressing on the support ring (30, 230) from a radially outer side thereof; and a sealing device (80) provided at each end of a fluid channel tube (60, 260) arranged within the fluid channel groove (11, 211). Two ends of the fluid channel tube (60, 260) pass through the rubber member (20, 220) radially to extend into two hydraulic chambers (40, 240) respectively, so that said two hydraulic chambers (40, 240) are in communication with each other through the fluid channel tube (60, 260). One end of the sealing device (80) is arranged inside the flow channel groove (11, 211) and the other end thereof passes through the rubber member (20, 220) to extend into the hydraulic chambers, thus forming a seal between the flow channel pipe (60, 260) and the flow channel groove (11, 211).

摘要： A method for increasing axial stiffness, reducing radial and deflection stiffness of an elastic compounded component, which can increase axial stiffness and reduce radial and deflection stiffness of the elastic compounded component by axial precompression and suspended load bearing structure its elastic subcomponent with multiple free surfaces, wherein the elastic subcomponent with multiple free surfaces is a compounded elastic component of elastic material and metallic components (2) , the elastic subcomponent has three or more free surfaces after being compounded, so that the stress of the elastic subcomponent in all directions is substantially reduced, and the fatigue life of the elastic subcomponent (3) is prolonged; the axial precompression means that the elastic subcomponent is always in an axial compressed state while they are working, so that the axial stiffness is substantially increased; the suspended bearing structure means (1) that at least one of the metallic component of the elastic subcomponent is in a suspended state while they are working, so that the metallic component does not bear the load in radial direction on one hand, and thus the elastic material at this position is in a shearing state completely and only provide very little radial and deflection stiffness, on the other hand, the suspended metallic component will bear the load in axial direction and make great contribution to axial stiffness, thereby increasing axial stiffness, reducing radial and deflection stiffness of the elastic compounded component.

摘要： Method and device for improving comprehensive performance of elastic suspension component of axleless bogie system, According to the structural feature of an axleless bogie, at least one elastic component is arranged in suspension system of the axleless bogie system; the elastic component is combined with a metallic component to form an elastic-metallic combination component; multiple free surfaces are provided for the elastic material component in the elastic-metallic combination component, stress release is realized by the multiple free surfaces of the elastic material component, therefore, the stress of the elastic material component of the axleless bogie in all directions is reduced. Providing multiple free surfaces of the elastic material component refers to designing free surfaces for the elastic material component at different angles and positions in the combination of elastic material component and the metallic component respectively according to the stress conditions of each component, so that stress can be released by the free surfaces when the elastic material component is stressed in all directions, and the stress of the elastic material component is reduced.

摘要： Disclosed are a method for improving overall performance of a rail vehicle bogie and a suspension damping system. The system rigidity of a torque arm node is adjusted by changing and adjusting torque arm node parameters so as to lower the longitudinal rigidity and the deflection rigidity of the torque arm node; meanwhile the axial rigidity is increased, such that a reduction in the torsional rigidity of the torque arm node is avoided. The structure of a vertical stop is changed to lower the vertical rigidity of a primary suspension. The structure of a supporting ball joint of an anti-side-roll torsion bar is changed to prevent the axial movement of the anti-side-roll torsion bar. The structure of a traction ball joint of a traction rod system component is adjusted to control the non-linear rigidity of the traction ball joint such that the non-linear rigidity of the traction ball joint has a smooth transition. The longitudinal rigidity, axial rigidity, torsional rigidity and deflection rigidity of the entire bogie are adjusted by changing the torque arm node and the vertical stop of the primary suspension system, changing the structure of the supporting ball joint of the anti-side-roll torsion bar of a secondary suspension system and changing the structure of the traction ball joint, such that the overall performance of the bogie is further improved.
