Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the non-pressure head of the existing train brake cylinder deforms during long-term work due to its uneven ventilation, and produces relatively loud noises when the train brakes. Therefore, it provides a Train brake cylinder without pressure head

Abstract

The invention discloses a train brake cylinder non-pressure head. The head comprises a horn-shaped body, the caliber of a rear end opening of the body is larger than that of a front end opening of thebody, an annular edge arranged towards the outer side of the rear end opening of the body is arranged on the rear end opening of the body, the annular edge is perpendicular to the central axis of thebody, an assembling hole and a plurality of air chambers evenly distributed along the circumference are formed in the annular edge, and a vent hole is formed in each air chamber; a lining part coaxial with the body is welded in the body, the lining part is composed of an annular lining plate and a center pipe, and the center pipe stretches out towards the rear side of the body. The head is compact in structure and good in mechanical performance, the balance and high efficiency of air inlet and outlet of the train brake cylinder on the pressure-free head side are guaranteed, the pressure-freehead is more stable in structure, and noise pollution is greatly reduced.

Description

technical field [0001] The invention relates to a headless head, in particular to a headless head for a train brake cylinder. Background technique [0002] Currently, train brake cylinders are used to control the braking operation of trains. see figure 1 , the train brake cylinder is made up of a cylinder body 4, a headless head and a piston rod assembly 5, wherein the headless head has a trumpet-shaped body 1, and the caliber of the rear port of the body 1 is larger than the caliber of the front port, and on the side wall of the body 1 There is a vent hole 2, and a dust filter 3 is installed at the vent hole 2; an air inlet hole 6 and an air outlet hole 7 are arranged on the cylinder body 4, and a return spring 8 is set on the rod body of the piston rod assembly 5, and the return spring The front end of 8 is installed in the spring seat 9, and the spring seat 9 is built in the front end of the body 1 without pressure head, and the rear end of the return spring 8 correspon...
