Single-cavity spring brake chamber for energy storage air break

Abstract

The invention discloses a single-cavity spring brake chamber for an energy storage air break, and aims to solve the problem of increase in cost due to waste of a membrane cavity under the condition that the membrane cavity in the conventional spring brake chamber is idle and not used. The single-cavity spring brake chamber comprises a cylinder block, a push rod disk, a push rod and a spring assembly, wherein the push rod disk is arranged in the cylinder block, can move along the axial direction of the cylinder block, and partitions the internal space of the cylinder block into an air cavity and a spring cavity; the air cavity and the spring cavity are arranged along the axial direction of the cylinder block; the air cavity is provided with an air inlet / outlet; one end of the push rod is fixedly connected to the push rod disk; the other end of the push rod passes through the end wall of the cylinder block along the axial direction of the cylinder block, and is positioned outside the cylinder block; a sealing assembly is arranged between the push rod and the cylinder block; the spring assembly is arranged in the spring cavity; one end of the spring assembly is pressed against the push rod disk; the other end of the spring assembly is pressed against the internal end wall of the cylinder block; thrusting force facing the outside of the cylinder block is applied to the push rod. Byadopting single-cavity spring brake chamber, the membrane cavity is omitted under the condition of not influencing the brake performance, and the production and usage cost is lowered.

Description

technical field [0001] The invention relates to a single-cavity spring brake chamber for an air-cut brake. Background technique [0002] A conventional spring brake chamber has a diaphragm chamber and a spring chamber. In many cases, the spring brake chamber only uses the spring chamber, causing the diaphragm chamber to be in an idle state, which wastes the diaphragm chamber and increases the cost burden. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a single-chamber spring brake chamber for an air-cut brake, which omits a diaphragm chamber without affecting the braking performance, thereby saving production and use costs. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A single-cavity spring brake chamber for an air-cut brake, comprising a cylinder body, a push rod disk, a push rod and a spring assembly; the push rod disk is arranged in the cy...
