Embodiment Construction

[0021] Such as figure 1 and as figure 2 As shown, a wind resistance brake device 100 includes a wind resistance brake plate 120 and a driving mechanism 140; the drive mechanism 140 includes a drive rod 142, and the drive rod 142 is hinged to the wind resistance brake plate 120; One end of the braking plate 120 is hinged to the fixing base 200 , and is driven by the driving rod 142 to rotate around the fixing base 200 .

[0022] Specifically, the windage braking plate 120 is provided with a mounting base, the mounting base includes a first mounting base 122 and a second mounting base 124, the first mounting base 122 is hinged to the fixing base 200, and the second mounting base 124 is hinged to the drive rod 142 . In this embodiment, the mounting seat and the windage brake plate 120 are integrally formed, so that the structure of the windage brake device 100 is simpler and the performance is safer.

[0023] It should be understood that the installation seat is provided to m...

Abstract

A wind resistance braking device comprises a wind resistance braking board and a driving mechanism; the driving mechanism comprises a driving rod; the driving rod is hinged onto the wind resistance braking board; and one end of the wind resistance braking board is hinged on a fixed seat and is driven by the driving rod to rotate around the fixed seat. The wind resistance braking board can be rotated around the fixed seat for a corresponding angle, and when airflow flows towards the wind resistance braking board, the wind resistance braking board can generate certain air resistance which directly pushes the wind resistance braking board to rotate through the driving rod, so that the required driving force is small, the efficiency is improved, and energy is saved; two wind resistance braking boards are symmetrically mounted on side wall plates on the two sides of a motor car body, so that a motor car keeps a good balance; rain water, dust and other impurities can not fall in the wind resistance braking device to influence the wind resistance braking device, so that the service life of the wind resistance braking device is prolonged; and the mounting areas of the two sides of the motor car body are large, so that the wind resistance braking device can be mounted and used conveniently.

Description

technical field [0001] The invention relates to the technical field of vehicle braking, in particular to a wind resistance braking device and a motor vehicle body using the wind resistance braking device. Background technique [0002] The traditional forms of train braking are tread braking, disc braking, regenerative braking or resistance braking, which rely on the adhesion between the wheel and rail, but the adhesion coefficient between the wheel and rail decreases with the increase of the train speed. The drop is more pronounced when the train speed is higher than 250km / h. With the large number of high-speed EMUs running at home and abroad with a train speed exceeding 250km / h, the traditional braking form can no longer meet the braking needs of high-speed EMUs in emergency situations. Contents of the invention [0003] Based on this, it is necessary to provide an air resistance braking device and an EMU using the wind resistance braking device for the problem that the ...
