Abstract

The invention discloses a variable gauge bogie provided with an adjustable unit braking device. The variable gauge bogie comprises a frame composition, a variable gauge wheel pair composition, a shaft box suspension device and a composite braking device containing a disc-shaped braking device and the adjustable unit braking device. The frame composition is of a H-shaped structure, and the rhombus resistance capacity is high; through the shaft box suspension technology, the unsprung mass is reduced, and vertical dynamic performance of a vehicle is improved; by adopting a variable gauge wheel pair, the operation requirements under different gauges are met; and the composite braking device comprises the disc-shaped braking device and the adjustable unit braking device, so that the requirement of a braking heat load under large shaft weight and high speed reduction under different gauge conditions is met. The variable gauge bogie is suitable for subway tunnels and railway main track vehicles with different gauges, and has strong social and economic benefits, the transport efficiency is improved, and transferring time is saved.

Description

technical field [0001] The invention relates to a variable-gauge bogie suitable for subway tunnels with different gauges and railway main line vehicles, and belongs to the technical field of railway transportation. Background technique [0002] At present, the trade volume between China and Europe is increasing year by year, among which railway transportation has greater advantages than sea and air transportation. However, different countries and regions have different railway gauges, which restrict the development of railway transportation. Due to differences in operating environments and braking conditions, subway tunnel vehicles and railway main line vehicles do not operate directly in subway tunnels and railway main lines at the same time. Vehicles, especially engineering vehicles with relatively large axle loads, cannot meet the requirements of frequent braking and large braking deceleration in subway tunnels, and the braking thermal load is high.
