Rail vehicle tilting system, tilt control method and rail vehicle

Abstract

Embodiments of the present invention provide a rail vehicle tilting system and tilting control method; the system includes a controller, a high-pressure air cylinder, a left air spring, a right air spring, an additional left air chamber, an additional right air chamber, a second A three-position electromagnetic proportional flow valve, a second three-position electromagnetic proportional flow valve, a sensor, a differential pressure valve, and a two-position switch valve; among them, the left air spring communicates with the left additional air chamber, and the right air spring communicates with the right additional air chamber. The air chamber is connected; the sensor is used to collect the data of the rail vehicle when it is running, and transmit the collected data to the controller; the controller controls the first three electromagnetic proportional flow valves and the second three electromagnetic proportional flow valves according to the data collected by the sensor. The electromagnetic proportional flow valve is used for control; the differential pressure valve is used to communicate with the left additional air chamber and the right additional air chamber; the two-position switch valve communicates with the left additional air chamber and the right additional air chamber respectively through pipelines.

Description

technical field [0001] The invention relates to the technical field of railway transportation, in particular to a rail vehicle tilt system, a tilt control method and a rail vehicle. Background technique [0002] When a rail vehicle runs on a curved road section, the centrifugal force generated will make passengers feel uncomfortable, and even cause an overturning accident in severe cases. [0003] For this reason, in the prior art, the outer rail is generally raised to a certain degree, and the centripetal force (centripetal force) produced by the body weight of the vehicle is used to balance the centrifugal force. This practice is also known as outer rail superelevation. [0004] However, the laying of railways will be constrained by natural conditions. In some difficult sections, the superelevation of outer rails is often insufficient, which limits the speed of rail vehicles passing through curves and reduces transportation efficiency. In addition, the speed-up operation...
