Embodiment Construction
[0036] The technical solution in the embodiment of this application is to solve the problem that the air spring in the prior art is prone to failure during actual use, and to ensure the normal operation of the rail vehicle. The general idea is as follows:
[0037] A shock absorbing spring is provided, and a novel structure of a shock absorber is designed, the shock absorber includes a first permanent magnet and a second permanent magnet, and the first permanent magnet and the second permanent magnet are oppositely arranged with the same polarity, When the two permanent magnets are close to each other, a repulsion force is generated, and the closer the distance is, the greater the repulsion force is, that is, the permanent magnet is equivalent to providing a flexible damping spring with variable stiffness, thus solving the problem of the air spring in the prior art in the actual use process. prone to failure issues.
[0038] In order to better understand the above-mentioned tec...

The invention discloses a damping spring which comprises a supporting part and a damping part. The damping part comprises a first magnetic assembly fixed to the supporting part, and a second magneticassembly installed on the supporting part, wherein the first magnetic assembly comprises a first permanent magnet which comprises a magnetic pole end, the magnetic pole end is perpendicular to the bottom face of the supporting part, the second magnetic assembly can slide in the direction perpendicular to the bottom face of the supporting part, the second magnetic assembly comprises a second permanent magnet, and the second permanent magnet and the first permanent magnet are arranged in the manner that the same polarity is opposite. The damping spring solves the problem that an air spring in the prior art breaks down easily in the actual use process, and then the operation efficiency of the railway vehicle is improved.
Description
technical field [0001] The invention belongs to the technical field of damping elements of a rail vehicle suspension system, and in particular relates to a damping spring and a rail vehicle. Background technique [0002] Rail trains will produce severe vertical vibration during high-speed operation, which affects the ride comfort of passengers. In order to solve the above problems, damping springs are usually installed between the car body and the bogie or suspension frame. Currently, rail trains use Air springs are mostly used as shock absorbing springs. [0003] Although air springs can improve riding comfort, the inventors of the present application found that air springs are prone to problems such as airbag failures during the process of implementing the technical solutions of the inventions in the embodiments of the present application, thereby causing inconvenience to the operation of rail vehicles. Contents of the invention [0004] The purpose of the present inven...
