Abstract

The invention provides a train wing plate decelerating device based on a worm wheel and worm transmission. The train wing plate decelerating device comprises two adjacent wing plate units, wherein a worm transmission mechanism is arranged between the two wing plate units, and the two wing plate units are mutually transmitted through the worm transmission mechanism; wing plate rotating shafts separately extending to the corresponding wing plate unit are separately arranged on two sides of the worm transmission mechanism; each wing plate unit comprises a mounting base plate for being mounted on a train roof; wing plates are arranged on the mounting base plate in a supporting manner; each wing plate is arranged on the corresponding wing plate rotating shaft in a sleeving manner, and the wing plates of the two wing plate units are separately and synchronously started backwards; the worm transmission mechanism comprises a step motor, the rotating speed and the rotating angle of the wing plate rotating shafts are controlled by the step motor, and the starting speed and the opening and closing angle of the wing plates are controlled. According to the train wing plate decelerating device disclosed by the invention, the transmission and the synchronous linkage of the wing plates are realized through a worm wheel and a worm, so that the safe reliability and the braking effect of the wind resistance of a train are further improved.

Description

technical field [0001] The invention belongs to the technical field of train vehicle braking, and relates to a train wing plate deceleration device based on worm drive. Background technique [0002] At present, with the increase of train running speed, the braking effect of traditional adhesive braking in the high-speed section is not enough to ensure the safe operation of the train. As a non-stick braking, wind resistance braking is not limited by sticking conditions. At the same time, the higher the running speed of the train, the greater the wind resistance braking force, which can meet the braking requirements of high-speed trains. Wind resistance braking Most of the wind resistance braking devices disclosed so far realize the opening and closing control through hydraulic pressure, air pressure or gear structure, but there are some problems such as large driving force required to open the wings, strict selection of installation positions, and occupying the interior spac...
