Static pressure adjusting device of rotating arm positioning bogie

By integrating a hydraulic/electromechanical control system for the slewing bogie's static pressure adjustment, the problems of uneven wheel-rail contact force, insufficient dynamic load adjustment, and stability and comfort under complex working conditions have been solved. This has enabled uniform distribution of wheel-rail contact force and smooth operation of the bogie, reducing wear and derailment risks and improving operational efficiency.

AI Technical Summary

Technical Problem

Existing swing arm positioning bogies suffer from uneven wheel-rail contact force, insufficient dynamic load adjustment capability, contradiction between stability and comfort, and poor adaptability to complex working conditions under high-speed, heavy-load, and complex track conditions, leading to accelerated wheel flange wear, increased derailment risk, and high operating costs.

Method used

The boom positioning bogie static pressure adjustment device, which adopts integrated hydraulic/electromechanical control technology, optimizes the static pressure distribution of the wheelset in real time through the controller and hydraulic push rod, dynamically adjusts the vertical load, and achieves uniform distribution of wheel-rail contact force and active or semi-active optimization of the bogie.

Benefits of technology

It achieves uniform distribution of wheel-rail contact force, reduces abnormal wear on wheel flanges and rail surfaces, improves the anti-hunting stability and ride comfort of the bogie, reduces derailment risk and operating costs, adapts to various complex working conditions, and extends the service life of key components.

Abstract

The utility model discloses a static pressure adjusting device for a tumbler positioning bogie, which relates to the technical field of railway vehicle bogie design and control and comprises a main cross beam, controllers are arranged on two sides of the upper surface of the main cross beam, damping components are mounted on two side surfaces of the main cross beam, and side support beams are mounted on the outer surfaces of the damping components. And penetrating measurement units are arranged at the tail ends of the four corners of the side supporting beam. Compared with an existing common bogie static pressure adjusting device, the static pressure adjusting device for the tumbler positioning bogie has the advantages that the controller controls the hydraulic push rod to automatically optimize the static pressure distribution of the wheel pairs and dynamically balance the wheel weight, the vertical load of each wheel pair is adjusted in real time, the unbalance loading phenomenon caused by the unsmooth track or uneven load is reduced, and the stability of the bogie is improved. And abnormal wear of the rim and the rail surface is reduced. Wheel-rail contact force is evenly distributed, abnormal abrasion is reduced, and the service life of wheel pairs, steel rails and key components of a bogie is prolonged.
