Abstract

The invention discloses a braking device. The braking device comprises an air cylinder used for controlling a proportionality coefficient, wherein the air cylinder is connected with an executive component by virtue of a pipeline; the air cylinder comprises a shell which can contain gas, the shell is provided with a through hole, a connecting rod can be inserted into the interior of the shell from the exterior of the shell through the through hole, and the connecting rod and the through hole are slidably connected by virtue of a screw thread; a baffle used for adjusting the volume of the shell is arranged inside the shell; one end, inserted into the interior of the shell, of the connecting rod is connected with the baffle; the circumference of the baffle and the inner side wall of the shell are in slidably tight fit; and a sealing element used for avoiding gas leakage of the shell is also arranged at the circumference of the baffle. The braking device has the advantages that the connecting rod is adjusted, so that the volume of the shell is regulated, and then regulation on the proportionality coefficient is conveniently realized.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a braking device. Background technique [0002] Generally speaking, the pressure of the locomotive brake cylinder is determined by the proportional coefficient, and the proportional coefficient is determined by the ratio of the volume of the working air cylinder to the volume of the pre-control air cylinder (including the corresponding pipeline). [0003] In the prior art, after the air cylinder controlling the proportional coefficient is manufactured and installed on the locomotive, its volume is fixed; if the proportional coefficient does not conform to the design, the proportional coefficient cannot be adjusted without replacing the air cylinder , so that the pressure of the brake cylinder does not conform to the standard, and there is a certain potential safety hazard. [0004] Therefore, how to conveniently adjust the volume of the brake air cylinder is a technical pr...
