Problems solved by technology

[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

Embodiment Construction

[0025] Attached below figure 1 , 2 Detailed description of the present invention:

[0026] An under-bearing wheel-rail running mechanism for an electric rail Airbus, the running mechanism includes at least four running mechanism units,

[0027] Each running mechanism unit includes an active wheel 1 and a passive wheel 19 on the opposite side of the active wheel 1. The active wheel 1 and the passive wheel 19 are rollingly connected in the seamless track 20, and the lower edge of the seamless track 20 is opposite to A pair of track height adjusting devices 21 are provided at the positions of the active wheel 1 and the passive wheel 19;

[0028] A load-bearing support beam 10 and a load-bearing frame girder 12 are provided at the lower part of the operating mechanism unit. A guide rod 14 is provided on the load-bearing support beam 10, and a steel ball 15 is provided at the upper end of the guide rod 14. A combined cylindrical spiral compression spring 11 is provided on both sides;

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.

Description

Technical field [0001] The invention relates to an under-bearing wheel-rail running mechanism of an electric rail airbus, belonging to the technical field of electric rail airbuses. Background technique [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, the increasing frequency of social activities, and the improvement of people’s living standards, urban traffic has grown rapidly at an unprecedented rate. The traffic and road facilities in China can no longer meet the needs of modern social development. [0003] How to alleviate the increasingly serious urban traffic congestion problem has become an urgent development problem for large and medium-sized cities. For this reason, it is imperative to vigorously develop the public rail transit system. The rail operation agency of the European rail transit system is to borrow The principle of the subway transp...
