Embodiment Construction

[0014] The accompanying drawings show an embodiment of the present invention, and the present invention will be further described below in conjunction with the accompanying drawings.

[0015] As can be seen from the accompanying drawings, the present invention is a truck axle box spring damping method for rail vehicle bogies, which adopts a two-stage damping method; the axle box spring is a composite axle box formed by a combination of a main spring and an auxiliary spring Spring; the main spring still adopts the current metal-rubber composite conical spring; on the main spring, there is a shear-type conical frustum rubber stack auxiliary spring. The auxiliary spring of the cone-truncated rubber stack with shearing force is located on the main spring, and absorbs the vibration by bearing the shearing force when the main spring is compressed and contacts it. The damping of the axle box spring is divided into two stages of damping. In the vertical direction, the rigidity series ...

Abstract

The invention relates to a goods van journal spring buffering method used for a railbound vehicle bogie and a journal spring. The method adopts a two-stage buffering way. The journal spring is a composite journal spring formed by combining a main spring and an assistant spring, wherein the main spring still adopts the prior metal-rubber composite conical spring, and a shearing stress frustum rubber pad assistant spring is arranged on the main spring. The shearing stress frustum rubber pad assistant spring is arranged on the main spring, thereby buffering by bearing shearing force when the main spring is compressed and contacted with the assistant spring. The composite journal spring is formed by combining a main spring and a shearing stress frustum rubber pad assistant spring, wherein the main spring is a metal-rubber composite conical spring, and the shearing stress frustum rubber pad assistant spring is connected to the main spring in series. The invention adopts a combination structure of the main spring and the assistant spring, utilizes the rubber to play the elastic buffering role, vertically, longitudinally and transversely provides flexible supporting and positioning for the bogie, transfers traction and brake force during running and improves the running quality of vehicles.

Description

technical field [0001] The invention belongs to a rail vehicle vibration damping method and components, in particular to a truck axle box spring vibration damping method and axle box spring for rail vehicle bogies, mainly used for rubber elastic components for various rail vehicle bogies At the same time, it can also be applied to any vibration-damping elastic connection parts such as construction machinery. Background technique [0002] The axle box spring on the truck bogie is set up to ensure the smooth and safe operation of the vehicle. It is installed between the axle box and the frame to play a series of vibration damping functions. [0003] At present, all types of trucks in China use metal round steel springs as axle box springs, and the metal round steel springs used alone have the same longitudinal and transverse rigidity and are relatively small. It is very difficult to achieve a large longitudinal stiffness required for stability (especially at high speed). For ...
