The invention provides a suspension system and method of a suspension type railway vehicle and the suspension type railway vehicle. The system comprises air springs and a suspension beam arranged on the suspension type railway vehicle, a plurality of independent additional air chambers are formed in the suspension beam, and the additional air chambers and the air springs are arranged in a one-to-one correspondence mode; and the valve body assembly is arranged on an air path where the air spring is connected with the additional air chamber and used for adjusting the communication state of the air spring, the additional air chamber and the external environment, and then the air pressure in the air spring is adjusted. The cavity of the suspension beam is arranged to be the additional air chamber of the air spring, so that the requirement for adjusting the air pressure in the air spring is met, and meanwhile, the weight of the whole vehicle is reduced.
本发明提供一种悬挂式轨道车辆的悬挂系统、方法及悬挂式轨道车辆,系统包括:空气弹簧,设置于悬挂式轨道车辆的悬吊梁,悬吊梁内部形成有多个彼此独立的附加气室,附加气室与空气弹簧一一对应设置;阀体组件,设置于空气弹簧和附加气室连接的气路上,用于调节空气弹簧、附加气室和外界环境的连通状态,进而实现调节空气弹簧内的风压。本发明通过将悬吊梁的空腔设置为空气弹簧的附加气室,保证了空气弹簧内风压的调节需求,同时减轻了整车重量。
