Railway vehicle roof airfoil profile board device and railway vehicle

Abstract

The invention relates to the technical field of railway vehicles, in particular to a railway vehicle roof airfoil profile board device and a railway vehicle. The provided railway vehicle roof airfoilprofile board device comprises a drive motor, a transmission assembly and an airfoil profile board. The drive motor is arranged on a vehicle roof of the railway vehicle, and an output shaft of the drive motor is arranged in the width direction of the vehicle roof. The transmission assembly comprises two rotary arms connected with the two ends of the output shaft of the drive motor, the two rotaryarms are connected with a rear beam of the airfoil profile board through rotary hinges, and the output shaft, the rear beam of the airfoil profile board and the two rotary arms jointly form a parallelogram mechanism. A front beam of the airfoil profile board is rotationally installed on the vehicle roof. The output shaft of the drive motor drives the transmission assembly to rotate around the output shaft, so that the attack angle of the airfoil profile board is controlled, aerodynamic lift is provided in the vehicle running process, and comfort and stability are improved; or aerodynamic resistance is provided in the vehicle braking process, the braking distance is shortened to improve the train braking efficiency, the structure is simple, and cost is low.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a rail vehicle roof airfoil device and a rail vehicle. Background technique [0002] At present, the equipment installed on the roof of ordinary high-speed trains is mainly pantographs, high-voltage equipment, air conditioners and other components. The roof equipment of high-speed trains with wind resistance braking function is also equipped with brake wind resistance wings, hydraulic control and actuators, etc. . However, the above two types of high-speed trains cannot provide aerodynamic lift for the whole vehicle through the relevant equipment on the roof, resulting in single function and energy consumption. Contents of the invention [0003] (1) Technical problems to be solved [0004] The first purpose of the present invention is: to provide a simple structure, reasonable design, low cost and when the rail vehicle is running or braking, it can effectively use the e...
