Embodiment 1
[0054] Such as figure 1 and image 3 As shown, a rubber joint composed of ends includes a base (3), a rubber layer (2), and a jacket (1). The base (3) includes a base inner hole (4) and a base shell (5). The jacket (1) includes a jacket inner hole (6) and a jacket shell (7);
[0055] The base inner hole (4) and the base shell (5) as well as the jacket inner hole (6) and the jacket shell (7) are all in the shape of a truncated cone, and the base shell (5) is nested in the jacket inner hole (6) There is a gap in the frustum-shaped space of the cone, and the rubber layer (2) is filled in the gap and vulcanized with the outer casing inner hole (6) and the base shell (5) to form a vulcanized layer.
[0056] Such as Figure 7 As shown, in this embodiment, the cross section of the base shell (5) is sequentially spliced from the top to the bottom by a column 12, a circular platform 13, a circular platform 14, a column 2 16 and a column 3 18 in a stepped manner, wherein the circul...

The invention provides an end part composition rubber joint. The end part composition rubber joint comprises a circular truncated cone-shaped base inner hole, a base outer shell, an outer sleeve innerhole and an outer sleeve outer shell, wherein a rubber layer fills a gap and is vulcanized with the outer sleeve inner hole and the base outer shell to form a vulcanization layer. According to the method for adjusting the rigidity of the end part composition rubber joint, the angle of the base inner hole and the angle of the circular truncated cone of the outer sleeve inner hole are adjusted, theradial direction and the axial rigidity of the rubber joint are formed by the adjusting end part, and tooth-shaped protrusions are arranged on the surface of the inner hole of the outer sleeve and the surface of the outer shell of the base, so that the thickness of the rubber layer is reduced, and the torsional rigidity or the axial stiffness of the rubber joint formed by the end part is increased. The end part composition rubber joint has high axial and radial rigidity, the rigidity can be adjusted, and the adaptability is good.
Description
technical field [0001] The invention relates to the technical field of rail vehicle rubber joints, in particular to a rubber joint composed of end parts and a method for adjusting stiffness; The stiffness in the direction cannot be adjusted, and belongs to the technical field of rubber joint stiffness adjustment. Background technique [0002] The rubber joint at the end is suspended on the front end of the subway bogie. The middle of the two products is installed to the side beam of the bogie through a shaft, and the intermediate shaft needs to be suspended with a signal transmission device. Therefore, the torsional stiffness, radial, and Axial rigidity is required. The two ends of the traditional rubber joint with a mandrel are fixed by mounting holes, which cannot meet the actual installation and application requirements, and its torsional stiffness, radial and axial stiffness cannot be adjusted, so it cannot meet the application requirements. [0003] By patent search, ...
