Four-shaft high-speed bogie for motorcycle

Abstract

The invention relates to a four-axis high speed turning frame used for s vehicle, which comprises a truss and four wheel sets, a driving device, a hanging mechanism, a brake device and a driving mechanism which are arranged on the truss, wherein, the wheel sets are arranged on the truss via the hanging mechanism, and each wheel set is respectively connected with the driving mechanism and the driving device which are arranged on the truss. The four wheel sets are divided into two groups in pairs, and two wheel sets in a same group are connected with each other via a balance beam of a bearing with a spherical surface axis box. The balance beam is fixed on the truss via a supporting shaft, and more than one screw spring is arranged between the balance beam and the truss. The four-axishigh speed turning frame has big traction power, big adhesion weight, big traction capability, good curved line passing performance and small friction consumption of a wheel track.

Description

technical field [0001] The invention mainly relates to the field of bogies of railway locomotives, in particular to a four-axle high-speed bogie for locomotives, which is especially suitable for railway locomotives with a speed of 200km / h. Background technique [0002] In the prior art, the bogie technology of electric locomotives with a speed of 200km / h is relatively mature in Europe, such as X2000, KTT, 1016, 101, S252, BB36000 and so on. Their power car bogie structures have their own characteristics, but they all adopt the design principles of high reliability, light weight, maintenance-free, and replacement parts; they all use a motor full-suspension structure to reduce unsprung weight to meet high-speed running performance, and carry out A large number of test and verification work have been carried out, and its safety and reliability have been verified by operation. [0003] Domestically, on the basis of summarizing SS8, SS9, DF11 and other quasi-high-speed locomotiv...

AI Technical Summary

Problems solved by technology

[0004] The above high-speed power bogies all adopt the 2-axis B0-B0 structure type, which cannot fully meet the requirements of my country's railway passenger and cargo transportation, mainly due to insufficient traction capacity

Although the C0-C0 six-axle 200km / h locomotive can improve the traction capacity, but the small radius curve has poor passing ability

Since the 200km / h locomotives in foreign advanced countries basically do not use C0-C0 axle locomotives, it is difficult to adopt the advanced and mature technology of B0-B0 axle locomotives on this axle locomotive
