Embodiment Construction

[0015] An embodiment of the present invention provides a non-powered bogie for a meter-gauge line, such as figure 1 and figure 2 As shown, the non-power bogie for the meter-gauge line includes a bogie frame 1, and two wheel sets 2 are arranged in parallel on the bogie frame 1, wherein each wheel set 2 includes an intermediate shaft 21 and two wheels 22; The sides of the two wheel sets 2 facing away from each other correspond to the position of each wheel 22 in the wheel set 2, and a tread braking device 3 is respectively provided for braking each wheel 22, wherein the tread braking device 3 The devices known to those skilled in the art to perform braking by friction between the brake shoe and the tread of the moving vehicle wheel will not be repeated here. In this embodiment, the tread braking device 3 is arranged on the side away from the two wheelsets 2, compared to being arranged on the opposite side of the two wheelsets 2, the installation and maintenance are more conven...

Abstract

The invention provides a non-powered bogie for a meter-gauge track. The non-powered bogie comprises a bogie frame, two wheel set assemblies are arranged on the bogie frame in parallel, and a tread braking device used for braking each wheel is arranged at the position, corresponding to each wheel in each wheel set assembly, of one of mutually-opposite sides of the two wheel set assemblies. The non-powered bogie for the meter-gauge track has the advantages that the tread breaking devices are arranged on the mutually-opposite sides of the two wheel set assemblies, so that mounting and maintenance are facilitated, space between the two wheel set assemblies can be saved, distance between shafts of the wheel set assemblies is shortened, vehicles pass through small radius curve tracks smoothly and beneficially, and interference of parts in the internal space can be prevented.

Description

technical field [0001] The invention relates to rail vehicle technology, in particular to a non-powered bogie for meter-gauge lines. Background technique [0002] The bogie is one of the most important components in the rational system of the EMU. Whether its structural design is reasonable or not directly affects the running quality, dynamic performance and driving safety of the railway vehicle. At present, the braking device in the bogie is generally implemented by installing a tread braking device corresponding to each wheel on the opposite side of the two wheel pairs, or setting a hub disc braking device on the central axis of the wheel pair. brake. [0003] However, the way of setting tread braking devices on the opposite sides of the wheel pair and setting the axle disk braking device on the central axis of the wheel pair is for meter-gauge vehicles. Due to the narrow track distance, the installation and maintenance of the braking device is difficult. It is very inco...
