Refined gauge gauge-variable bogie wheel set locking mechanism

Abstract

The invention discloses a refined gauge gauge-variable bogie wheel set locking mechanism which comprises a lock sleeve, a key cover, a key, an unlocking pull rod, a trapezoid lock arm and a lock spring. The mechanism is suitable for narrow gauges, standard gauges and wide gauges with five gauges of 1,676 mm, 1,520 mm, 1,435 mm, 1,372 mm and 1,067 mm, a lock block is meshed with a lock groove of the lock arm, and the device is in a locking state so that wheels and a shaft sleeve can be prevented from moving axially along an axle; when the gauge changes, the lock block is separated from the lockgroove of the lock arm, the device is in an unlocking state and matched with an end surface driving device to complete gauge changing. According to the refined gauge gauge-variable bogie wheel set locking mechanism, accurate gauge changing of refined gauges is realized by the aid of the meshing of the lock block and the look groove of the lock arm and the design of the look groove.

Description

technical field [0001] The invention belongs to the technical field of bogie systems, and relates to gauge changing technology, in particular to a wheel set locking mechanism of a variable gauge bogie with subdivided gauge. Background technique [0002] With the vigorous development of the Silk Road Economic Belt, my country has carried out larger-scale, higher-level, and deeper regional cooperation with countries along the route, and is committed to building an all-round interconnection network. Among them, railway transportation has increasingly become the most important part of the Eurasian road. However, railways with different gauge specifications in different countries and regions have brought many restrictions to the development of international intermodal transport. [0003] At present, the conversion of the gauge of the bogie is mostly realized manually, which is time-consuming and labor-intensive. Therefore, for railways with different gauges, domestic and foreign ...
