The invention discloses an air duct for an urban rail vehicle, which comprises an air duct structure I and an air duct structure II, and the air duct structure I and the air duct structure II are aligned and communicated; a plurality of partition plates are arranged in the first air duct structure and the second air duct structure in a penetrating mode, and a corridor passing air duct and a side air duct are defined by the partition plates in the first air duct structure and the second air duct structure. The air volume adjusting mechanism has the beneficial effects that the movable block moves relative to the baffle to adjust the cross sectional area of the through hole for air flow to pass through by controlling the suction force of the electromagnet to the armature, and then the air volume in the corridor-passing air channel and the side air channel is adjusted, and the movable block does not make contact with the baffle in the adjusting process; in the working process of the air volume adjusting mechanism, all parts do not have any contact collision and transmission structure, so that the air volume adjusting mechanism can adjust the air volume without noise, the air volume adjusting mechanism does not need to be lubricated and maintained, and the problem that noise is generated when a current air volume adjusting mechanism works to affect passengers is effectively solved.

    本发明公开了一种用于城轨车辆的风道,包括风道结构一和风道结构二,所述风道结构一和风道结构二对齐连通;所述风道结构一和风道结构二内贯通设置有多块隔板,多块隔板在风道结构一和风道结构二内限定出过廊风道和侧风道。有益效果:风量调节机构通过控制电磁铁对衔铁的吸力大小来实现活动块相对挡板移动调节供气流通过的通孔的横截面积,继而调节过廊风道和侧风道内的风量,调节过程中活动块与挡板不接触,风量调节机构工作过程中各部件没有任何接触碰撞和传动结构,因此风量调节机构可以做到无噪音调节风量,风量调节机构也不需要润滑保养,有效解决了当前的风量调节机构工作时产生噪音影响乘客的问题。
