Embodiment 1

[0035] see figure 1 , this embodiment provides a rubber ball joint that reduces the radial / axial stiffness ratio. The rubber ball joint includes a metal mandrel 1, a rubber layer 2, a metal jacket 3 and a metal end cap 4. The rubber layer 2 is vulcanized and bonded to the metal On the mandrel 1, the metal jacket 3 is set on the outside of the rubber layer 2 and the metal end cap 4, and the metal end cap 4 is directly assembled or vulcanized and bonded to both ends of the rubber layer 2 to prevent the rubber from extruding from both ends of the rubber layer 2 .

[0036] Such as figure 2 As shown, the metal end cap 4 includes a stepped portion 41 and an annular portion 42, the annular portion 42 is connected to one end of the stepped portion 41, the annular portion 42 and the stepped portion 41 are transitionally connected by a fillet-43, and the circle of the fillet-43 The radius of the arc is R1, and the metal end cap 4 is wrapped into a whole by the flanging of the metal j...

Abstract

The invention relates to a rubber ball hinge for reducing the radial / axial rigidity ratio and an assembling method of the rubber ball hinge. The rubber ball hinge for reducing the radial / axial rigidity ratio comprises a metal mandrel, a rubber layer, metal end covers and a jacket. The rubber layer is vulcanized to be bound between the metal mandrel and the metal end covers, and the metal jacket isarranged on the outer sides of the rubber layer and the end covers and used for preventing rubber of the rubber layer from being extruded out. According to the rubber ball hinge, the end covers are arranged at the two ends of the rubber layer, bulging of the rubber at the two ends of the rubber layer can be effectively reduced, the outer molded surface of the rubber is scientifically and reasonably designed, the rubber layer deforms to bulge from a first end face to the inner side of the metal jacket, and bulging of the rubber on the bonding portion of the two ends of the rubber layer, the rubber layer, the metal jacket and the mandrel can be effectively reduced; and meanwhile the positions, close to the jacket and the mandrel, of the molded surfaces of the rubber are not prone to wrinkling or cracking, and the service life of the rubber ball hinge can be effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle elastic components, and in particular relates to a rubber ball joint with reduced radial / axial stiffness ratio and an assembly method thereof. Background technique [0002] The rubber ball joint for vehicle hydraulic shock absorber is a kind of elastic connecting element with excellent performance made of rubber and metal. The ball joint mainly uses rubber for vibration damping and buffering, and metal parts for support and installation interface. The ball joint can withstand complex working environments, including axial, radial, torsional, deflection and other multi-directional loads. and instant mechanical shock. Therefore, rubber ball joints are widely used in the field of rail vehicles. [0003] The general structure of the existing rubber ball joint is a mandrel, a jacket, and a rubber layer. The rubber end surface area of ​​the product is too large. During the use of the ball joint, t...
