The invention belongs to the technical field of railway braking, and discloses an automatic parking braking device for a passenger train and a braking method thereof. Two ends of a cam fixed swing rodand the ends of a cam gap adjusting swing rod of the braking device are movably connected with two braking connecting rods and a sliding seat correspondingly. The sliding seat is connected into a sliding groove of a self-locking mechanism base in a sliding mode, and a parking braking air cylinder is arranged in the sliding groove. The sliding seat is elastically connected with a gap adjusting wedge-shaped sliding block. The braking method comprises the following steps that the sliding seat slides into the sliding groove, the cam fixed swing rod and the cam gap adjusting swing rod move in thedirection of the sliding groove, one ends of the two braking connecting rods get close to the sliding seat, the two braking pads get away from a braking wheel disc, automatic relieving is achieved, and otherwise braking parking is achieved. According to the invention, during braking and parking, the operation time is short, the efficiency is high, effective braking can be ensured, an anti-slip iron shoe does not need to be placed manually, the labor intensity is low, the possibility of omission when anti-slip measures are removed does not exist, and the safety is higher.

    本发明属于铁路制动技术领域,公开了一种铁路客车自动驻车制动装置及其制动方法。本发明制动装置凸轮定摆杆的两端与凸轮调整间隙摆杆的两端分别活动连接两个制动连杆和滑动座;滑动座滑动连接于自锁机构基座的滑槽内,滑槽内设置有驻车制动气缸;滑动座上弹性连接有间隙调整楔形滑块。本发明制动方法步骤如下:滑动座向滑槽内滑动,凸轮定摆杆和凸轮调整间隙摆杆向滑槽方向移动,两个制动连杆的一端向滑动座靠拢,两个制动闸片远离制动轮盘,实现自动缓解,反之实现制动停车。本发明可以使得在制动停车时,作业时间短,效率高,同时可以保证有效制动,不再需要人为的放置防溜铁鞋,劳动强度小,不存在解除防溜措施时遗漏的可能性,更加安全。
