Braking module applicable to passenger train with center sill on underframe

Abstract

The invention relates to a braking module applicable to a passenger train with a center sill on an underframe. A life air cylinder, a working air cylinder, a sub air cylinder, a distribution valve, a gas control unit and a gas pipe are lifted under lifting frame; the gas control unit is fixed in a protective cover; the protective cover is fixed under the lifting frame; the lifting frame is formed by a longitudinal beam and a cross beam, which are welded with each other; the middle part of the longitudinal beam is fixed under the underframe of the train through a middle lifting seat; the upper part of the middle lifting seat is welded and fixed together with the underframe of the train; a gap allowing the longitudinal beam of the lifting frame to be inserted is formed in the bottom end of the middle lifting seat; a transitional backing plate which stretches over the gap is fixed at the bottom end of the middle lifting seat through a bolt; and the longitudinal beam falls on the transitional backing plate and is fixed together with the transitional backing plate through a bolt. According to the invention, as a braking system of the passenger train with the center sill is designed in a modularized way and passes production verification, the product quality is improved, the production efficiency and enterprise economic benefit are increased, and market adaptability capacity of the product is also enhanced.

Description

technical field [0001] The invention relates to a brake module suitable for a railway passenger car with a center girder on an underframe, and belongs to the technical field of rail vehicle brake systems. Background technique [0002] For a long time, the braking system of railway passenger cars has adopted a modular design, because the underframe of some railway passenger cars (such as luggage cars, etc.) has the limitation of the center beam running through the whole vehicle and the distribution of multiple fish-bellied main beams in the vehicle. Two electrical conduits with a diameter of 76mm are installed on both sides of the vehicle, so the brake system is not installed in a modular manner like other types of railway passenger cars, and the components are independently hoisted on the bottom of the car body by bolt fastening On the frame, the individual brake components are connected through brake pipes, so that all the assembly is carried out on the vehicle, which bring...

[0002] For a long time, the braking system of railway passenger cars has adopted a modular design, because the underframe of some railway passenger cars (such as luggage cars, etc.) has the limitation of the center beam running through the whole vehicle and the distribution of multiple fish-bellied main beams in the vehicle. Two electrical conduits with a diameter of 76mm are installed on both sides of the vehicle, so the brake system is not installed in a modular manner like other types of railway passenger cars, and the components are independently hoisted on the bottom of the car body by bolt fastening On the frame, the individual brake components are connected through brake pipes, so that all the assembly is carried out on the vehicle, which brings great inconvenience to the assemblers. Even if the designed brake pipe size is very accurate, sometimes it will Due to process errors, the brake components cannot be connected well, resulting in waste of materials and increased costs and man-hours
