Problems solved by technology
However, the traditional conical rubber spring cannot provide damping force, and there is no energy-absorbing device similar to a shock absorber. Although it can effectively isolate the vibration generated by the wheel rail and achieve the effect of vibration isolation, it cannot absorb the energy generated by the vibration and effectively attenuate the vibration amplitude. , which is detrimental to the overall dynamic performance of the bogie
And the rubber material is easy to react with substances such as engine oil, resulting in structural failure

Embodiment Construction
[0017] Refer to attached figure 1 The specific embodiment of the present invention is that the capsule 7 is integrated in the inner cavity 8 of the conical rubber spring, the groove 3 is arranged on the cover plate 2 of the conical rubber spring, the upper end of the mandrel 9 of the conical rubber spring is provided with a boss 1 along the circumference of the inner wall, and the boss There is a groove on the inner side of the upper edge, the upper edge of the capsule is placed in the groove of the cover plate, and the lower edge of the capsule is placed on the boss and fits with the groove on the inner side of the upper edge of the boss. The upper part of the conical rubber spring corresponds to the capsule and installs a metal part 4 as an interface for connecting the side beam of the frame. The metal part is trapezoidal, and the outer edge of the trapezoidal bottom edge is pressed on the cover plate 2 to press the outer edge of the upper part of the capsule 7 and fasten it....

Disclosed is a vibration reduction conical rubber spring mechanism. The mechanism is characterized in that a capsule is integrated inside a cavity inside a conical rubber spring, the upper end of thecapsule is installed on a cover plate, the lower end of the capsule is installed on a central spindle, a metal piece is connected to the upper portion of a conical rubber spring as a connector for being connected with a framework side beam, an O-shaped sealing ring is arranged outside the metal piece, and a throttling hole is formed in the center inside the metal piece; a boss needed by capsule installation is arranged at the upper end of the conical rubber spring central spindle along the circumference of the inner wall, a groove is formed in the inner side of the box, and the lower edge of the capsule is arranged on the boss and matched with the groove; compared with the prior art, the mechanism has the advantages, by arranging the capsule and the throttling hole inside the inner cavityof the spring, air can generate damping force in the throttling hole process, vibration energy is dissipated, and the vibration reduction effect is achieved; by adopting the pressure air structure, rubber degeneration caused by damping medium leakage is avoided; the mechanism is consistent with an existing vehicle connector, and installation of other structures is not affected.
Description
technical field [0001] The invention relates to a vibration-damping rubber spring of a primary suspension system of a rail vehicle, in particular to a conical vibration-damping rubber spring mechanism of a primary suspension mechanism. Background technique [0002] The existing urban rail vehicle bogie primary suspension system mainly has two forms of steel spring and conical rubber spring. In the swing arm steel spring primary suspension system, the steel spring is connected in parallel with the oil pressure shock absorber to achieve the purpose of vibration isolation and energy absorption. This structure can adjust the damping force by adjusting the parameters of the oil pressure shock absorber, but the parallel oil pressure The shock absorber and the steel spring are not on the same center, which will cause partial load, and the overall structure takes up a lot of space, which is not conducive to the layout of the bogie equipment. The traditional conical rubber spring pr...
