Abstract

The invention provides a breathing dust filter and a basic braking device. The breathing dust filter comprises a body, a first air duct is formed in the body, an air vent is formed in the side wall ofthe first air duct, the air vent penetrates through the body in the extension direction of the first air duct, one end of the body is an opening end to form a first wind outlet of the first air duct,the other end of the body is a closed end to seal the first air duct, and the basic braking device comprises the breathing dust filter. According to the breathing dust filter and the basic braking device, water entering in the breathing dust filter is reduced, and the waterproof property of the breathing dust filter is improved.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle braking, and in particular relates to a breathing dust filter and a foundation braking device. Background technique [0002] The breathing dust filter (hereinafter referred to as the respirator) is an indispensable part of the basic braking device of the railway vehicle. During the braking and release process of the vehicle, the inner cavity of the basic braking device and the outside world will have a breathing effect of gas exchange. The respirator is installed in the breathing channel to play the role of passive breathing and dust filtering. [0003] Such as figure 1 As shown, the existing breathing dust filter comprises a respirator body 1, a dust filter net 2 and a retaining ring 3, wherein the respirator body 1 is fixedly installed on the base body of the foundation brake by a threaded connection, and the inside of the respirator body 1 An air duct is formed, the air duct runs throug...
