The invention provides a wind generating device, a parking braking system and a train, the wind generating device is used for the parking braking system of the train, the train is provided with a train body and a support which float relatively, the parking braking system is connected with the train body and the support, and the wind generating device comprises a piston assembly, a rotating assembly, an exhaust assembly, an air inlet assembly and a limiting assembly. The piston assembly comprises a main body with a cavity and a piston located in the cavity, the main body is connected with the vehicle body, the piston is rotationally connected with the rotating assembly, the exhaust assembly and the air inlet assembly communicate with the cavity, and the limiting assembly communicates with the exhaust assembly. The piston is driven to move in the cavity to drive the air to enter the cavity, so that the air is exhausted and sucked, and air pressure is formed to drive a parking braking system; or the air is driven to enter the limiting assembly until the limiting assembly is clamped with the piston, and parking braking is stopped, so that the efficiency can be improved, and the pressure of a user is reduced.
本申请提供了一种制风装置、驻车制动系统及列车,制风装置用于列车的驻车制动系统,列车具有相对浮动的车体与支架,驻车制动系统连接车体与支架,制风装置包括活塞组件、转动组件、排气组件、进气组件以及限位组件,活塞组件包括具有空腔的主体,以及位于空腔内的活塞,主体与车体连接,活塞与转动组件转动连接,排气组件与进气组件均与空腔连通,限位组件与排气组件连通,当车体与支架相对浮动时,车体带动转动组件相对支架移动,并带动活塞在空腔内移动,驱动气体进入空腔,实现气体的排出与吸入,形成气压,以驱动驻车制动系统;或驱动气体进入限位组件,直至限位组件与活塞卡接,驻车制动停止,可以提升效率,减小使用者的压力。
