Structural design method and assembling method of integrated supporting spherical hinge

Abstract

The invention relates to the technical field of railway vehicle damping, and particularly discloses a structural design method of an integrated supporting spherical hinge. The supporting spherical hinge comprises an inner sleeve and a rubber sleeve, the inner sleeve is of a two-piece tile type structure which is oppositely mounted, the two pieces of inner sleeves are oppositely mounted at the end face in an attached mode; and an integrated rubber sleeve is arranged on the outer side of the oppositely-mounted two-piece inner sleeve to form the integrated supporting spherical hinge; an axial folding concave surface is arranged in the position, located on the first butt joint face of the two-piece inner sleeve, on the integrated rubber sleeve; an axial opening symmetric with the folding concave surface along the spherical hinge shaft is formed in the position, located on the second butt joint face of the two-piece inner sleeve, on the integrated rubber sleeve; and the spherical hinge can be folded through the folding concave surface and opened towards the two sides at the opening so as to be arranged on a torsion bar in a sleeving mode. The invention further discloses an assembling method of the integrated supporting spherical hinge.

Description

technical field [0001] The invention relates to a structural design method and an assembly method of an integrated supporting spherical joint, belonging to the technical field of rail vehicle shock absorption. Background technique [0002] The supporting ball joint is generally used in the anti-rolling torsion bar system of rail vehicles, and is installed in the mounting seat of the anti-rolling torsion bar system on the torsion bar. The rod system is used for shock absorption and is used to connect the supporting torsion bar and the mount. Most of the existing supporting spherical joints are as follows: figure 1 The two-petal tile structure shown includes a first petal ball joint 1 and a second petal ball joint 2, the first petal ball joint 1 includes a first petal inner sleeve 101 and a first petal rubber sleeve 102, and the second petal ball joint The hinge 2 includes the second petal inner sleeve 201 and the second petal rubber sleeve 202; when assembling, the first pe...

Problems solved by technology

[0003] 1. For the supporting ball joint with two-petal tile structure, it is difficult to ensure the radius and coaxiality of the two-petal spherical joint installed in the process of processing, which will affect the shock absorption and connection support effect of the supporting ball joint; The valve ball hinge and other components cannot be precisely positioned, which increases the difficulty of installation with other components

[0004] 2. The rubber sleeve profile 1 on one side of the outer end faces of the first ball joint 1 and the second ball joint 2 in the circumferential direction is different from the rubber sleeve profile 2 4 on the other side, that is, the sealing part of each ball joint It is an asymmetric structure, which has the problems of poor sealing effect, poor dust and water resistance at both ends of the ball joint, which will easily cause corrosion damage to the torsion bar and reduce the service life of the product

[0005] 3. During the assembly process of the split ball hinge, a workpiece is required to press the first ball hinge 1 on one side of the torsion bar, and then use the second workpiece to connect the second ball hinge 2 with the first valve. The ball joint 1 is pressed on the other side of the torsion bar relative to the first ball joint 1 relative to the sleeve. At this time, in order to prevent the first ball joint 1 and the second ball joint 2 from falling, the first workpiece and The second workpiece needs to compress the first ball joint 1 and the second ball joint 2 at the same time, and then use the two-petal mounting base to press the two-petal ball joints, the assembly cost is high and the assembly efficiency is low
