Axle box device of non-power wheel pair of D-series high-speed train for realizing standard gauge and wide gauge conversion

Abstract

The invention provides an axle box device of a non-power wheel pair of a D-series high-speed train for realizing standard gauge and wide gauge conversion. The device is characterized in that a slidingmechanism is mounted on a non-power axle; a non-power wheel and an axle box assembly sleeve the sliding mechanism and are fixed on the sliding mechanism; the sliding mechanism is used for driving thenon-power wheel to slide on the non-power axle when a gauge is changed and used for being matched with the non-power axle to transfer torque so as to drive the non-power wheel to rotate during operating; a locking mechanism is arranged between the sliding mechanism and the axle box assembly and is used for locking and fixing the sliding mechanism before and after the gauge is changed; a bearing base is mounted at the bottom of the axle box assembly and is used for bearing a vehicle when the sliding mechanism slides; and axial positioning mechanisms are arranged at two ends of the non-power axle and are used for realizing axial positioning of the axle. The structure can enable the distance between the inner sides of the wheel pair to adapt to a new gauge value, thereby solving the problemsin the prior art that the distance between the inner sides of the wheel pair is fixed and can not adapt to gauge change and a bogie needs to be replaced.

Description

technical field [0001] The invention relates to a non-powered wheel-to-axle box device for a high-speed train set, in particular to a non-powered wheel-to-axle box device for a high-speed train set that can realize quasi-wide gauge conversion. Background technique [0002] Because countries around the world adopt different railway gauge systems (for example, China’s railways are standard gauge with a gauge of 1435mm, and the railways of Russia and most countries in Eastern Europe and Central Asia are wide gauge with a gauge of 1520mm. In the process of cross-border transport Among them, when domestic passenger and freight railway vehicles run from standard-gauge lines to wide-gauge lines, they cannot pass directly, and need to stop and replace bogies that meet the requirements of different gauges. [0003] In the traditional bogie non-powered wheel-to-axle box device, the non-powered wheels are installed on the axle through interference fit, and the two are relatively fixed,...

AI Technical Summary

Problems solved by technology

When passing lines with different gauges, it is necessary to stop and go back to the warehouse to replace the bogie that adapts to the new gauge before continuing to operate. There are many problems such as increased manpower and material costs, long time consumption, and low operating efficiency.
