Lower bearing-type wheel rail operation mechanism of electric railway empty coach

Abstract

The invention relates to a lower bearing-type wheel rail operation mechanism of an electric railway empty coach, and the mechanism belongs to the technical field of electric railway empty coaches. The operation mechanism comprises at least four operation mechanism units; each operation mechanism unit comprises a driving wheel and a driven wheel which is arranged on the opposite side of the driving wheel; the driving wheels and the driven wheels are connected in a seamless railway in a rolling way; a pair of railway height adjusting devices are arranged at positions on the lower edge of the seamless railway which are opposite to the driving wheel and the driven wheel; and according to the structure, based on a three-point balance principle, height difference is difficult to eliminate on both railway surfaces on one side which is vertical to an operation direction; in addition, a high and a low super-high slopes are needed for running on a curve; and in such a manner, the running on an uneven railway surface is adjusted only by a steel ball and a combined cylindrical spiral compression spring, so that stable operation is realized. The lower bearing-type wheel rail operation mechanism of the electric railway empty coach has the advantages of high safety coefficient of operation, elaborate and simple structure, low cost and wide application prospect.

[0002] In today's society, traffic congestion has become one of the problems that plague urban development. Especially in recent years, with my country's urban economy and trade, social activities have become increasingly frequent, and people's living standards have improved, urban traffic has grown rapidly at an unprecedented rate. Traditional The traffic and road facilities can no longer meet the needs of the development of modern society

[0003] How to alleviate the increasingly serious problem of urban traffic congestion has become a developmental problem that large and medium-sized cities urgently need to solve. Therefore, it is imperative to vigorously develop the public rail transit system. The principle of the subway transportation system leads to the heavy passenger car box body, and the capacity of each passenger car is limited, and the manufacturing cost is high
