The invention discloses an internal breathing type spring brake chamber which comprises a brake chamber body, an air inlet filter box is arranged on the side face of an air inlet cavity, moisture absorption cotton, a first filter screen and a second filter screen are movably clamped in the air inlet filter box in sequence, and a rotating shaft is arranged between the first filter screen and the second filter screen. Guide vanes are fixedly connected to the side face of the rotating shaft in the circumferential direction, a gear is connected to the bottom of the rotating shaft, an eccentric wheel is movably connected to the inner wall of the air inlet filter box, and an eccentric connecting rod is hinged to the eccentric wheel. According to the internal respiration type spring brake chamber, water vapor in air is absorbed through the moisture absorption cotton, the structure is simple, when the air passes through the flow guide blades, the flow guide blades are driven to rotate, the eccentric connecting rod is made to move left and right, dust blocked on the first filter screen and the second filter screen is shaken off, automatic cleaning is achieved, and the manual cleaning frequency of workers is reduced.
本发明公开了一种内呼吸式弹簧制动气室,包括制动气室本体,所述进气腔侧面设置有进气过滤盒,所述进气过滤盒内依次活动卡接有吸湿棉、第一滤网和第二滤网,所述第一滤网和第二滤网之间设置有转轴,所述转轴侧面周向固定连接有导流叶片,所述转轴底部连接有齿轮,所述进气过滤盒内壁上活动连接有偏心轮,所述偏心轮上铰接连接有偏心连杆。该种内呼吸式弹簧制动气室通过吸湿棉对气体中的水汽进行吸收,结构简单,当气体通过导流叶片时,带动导流叶片旋转,使得偏心连杆左右移动,将堵塞在第一滤网和第二滤网上的灰尘抖落下来,实现自动清理,减少人员人工清理的频率。
