Rail vehicle bogie and rail vehicle with eddy current braking device

Abstract

The invention relates to a rail vehicle bogie with eddy current brake devices, and the rail vehicle. The bogie comprises a framework, wheel pair axle box positioning systems mounted at the end of theframework, foundation brake devices and the eddy current brake devices mounted below the framework, the framework comprises two side beams and two main crossbeams connecting the middle sections of theside beams on the two sides, the middle sections of the side beams are sunken downwards, longitudinal beams are mounted at the two ends of the main crossbeams in a sleeving mode and connected with the two main crossbeams, the two ends of the longitudinal beams are connected with auxiliary crossbeams, and the auxiliary crossbeams are located on the outer sides of the main crossbeams; and the wheelpair axle box positioning systems are connected to the ends of the two side beams, the foundation brake devices are mounted on the outer sides of the auxiliary crossbeams, and the eddy current brakedevices are mounted at the ends of the auxiliary crossbeams. A rail train comprises a train body and the bogie mounted at the bottom of the train body. The technical problems of large braking distance, serious sliding, wheel pair abrasion, long moving block interval and the like of a traditional high-speed bogie adopting adhesion braking are solved, and the braking performance of the train in high-speed operation is improved.

Description

technical field [0001] The invention belongs to the technical field of rail transportation, and in particular relates to a rail vehicle bogie and a rail vehicle. Background technique [0002] As one of the important components of rail vehicles, bogie components and performance parameters of each component play a vital role in the running quality, dynamic performance and passenger transportation safety of rail vehicles. [0003] In the prior art, the bogie braking system mostly adopts electric braking, disc braking or brake shoe braking. Since the braking effect of the above-mentioned braking method is affected by the adhesion performance between the wheel and rail, when the rail vehicle is running at high speed, the adhesion between the wheel and rail is significantly reduced, and the above-mentioned braking method will increase the braking distance, Severe skid, wheelset scratches and other technical problems. With the launch of the domestic 400km / h high-speed rail projec...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at the above-mentioned problems such as large braking distance, serious sliding, wheel set abrasion and the like existing in the braking process of existing rail vehicles during high-speed operation, and provides a rail vehicle bogie with an eddy current braking device and a rail vehicle , the bogie can realize the effective braking of the rail vehicle at high speed, without being affected by the adhesion performance between the wheel and rail, and improve the braking performance of the train at high speed
