Problems solved by technology

When the height of the carriage is high, on the one hand, problems such as a decrease in stability will be caused by the raised center of gravity; on the other hand, it is necessary to build a tunnel with a larger cross-section, which makes the project cost higher

Embodiment 1

[0029] This embodiment provides a carriage, which can be applied to a rail vehicle. The rail vehicle can be an EMU, a subway, a light rail, a maglev vehicle, or a tram.

[0030] In this embodiment, the length direction of the carriage is the same as the traveling direction of the rail vehicle. The length direction of the carriage is called the longitudinal direction, the width direction of the carriage is called the transverse direction, and the height direction of the carriage is called vertical or vertical.

Abstract

An embodiment of the present application provides a carriage and a rail vehicle, wherein the carriage includes: a carriage body and an air duct extending in the longitudinal direction; the interior space of the carriage is formed in the carriage body; In the roof recessed space for accommodating the air-conditioning unit, the roof recessed space penetrates from one end of the roof to the other end along the longitudinal direction; the air duct is arranged in the interior space of the vehicle compartment and is located on both lateral sides of the roof recessed space; The air duct runs through from one end of the compartment to the other end; the top of the car body is provided with a roof air outlet, and the air duct is provided with a first air outlet and a second air outlet; the first air outlet is connected to the air conditioner through the roof air outlet. The air supply ports of the unit are butted and connected, and the second air supply port faces the interior space of the compartment, which can reduce the vertical height of the compartment.

Description

technical field [0001] The present application relates to a carriage structure of a rail vehicle, in particular to a carriage and a rail vehicle. Background technique [0002] Rail vehicles are an important transportation link connecting cities, and have gradually become the main means of transportation in cities. Rail vehicles are also the main carrier for cargo transportation. The rail vehicle is composed of multiple carriages connected in series. An air-conditioning unit is installed above the roof of each carriage, and a running system is installed under the chassis of the carriage. The distance between the top of the air-conditioning unit and the bottom of the running system is the height of the carriage. When the height of the carriage is high, on the one hand, problems such as a decrease in stability will be caused by the raising of the center of gravity; Contents of the invention [0003] In order to solve one of the above-mentioned technical defects, an embodimen...
