A right brake cylinder body multi-cavity composite casting structure
By designing a multi-cavity composite casting structure for the right brake cylinder, the area difference between the annular push frame and the inclined block is used to reduce the burden on the oil pump, thus solving the problem of excessive oil pump load when the single-cavity brake cylinder is pressurized, achieving the effects of stability and extended life.

AI Technical Summary
Technical Problem
Existing single-chamber brake cylinders require a large and constant force to push the piston for braking when pressurized, resulting in excessive load on the oil pump and affecting its service life.
Method used
A multi-cavity composite casting structure for the right brake cylinder is designed. By setting an annular push frame and an inclined block in the pressure chamber, the area difference is used to reduce the burden on the oil pump, and the stability and buffering effect are maintained by the compensation groove and spring structure.
Benefits of technology
It effectively reduces the burden on the oil pump, extends the service life of the brake disc, maintains pressure stability, and reduces the workload of the oil pump.

Abstract
The utility model relates to the technical field of brake cylinder body structure, concretely to a right brake cylinder body multi -cavity composite casting structure, including pressure cabin, the pressure cabin top is connected with pressurizing cabin, the below of pressure cabin is provided with brake disc, one side of pressurizing cabin is provided with the connecting port, and the position between the oil injection pressurization of oil pump connected through the setting connecting port to annular chamber baffle and annular push frame, makes annular push frame slide in annular chamber inner wall, through annular push frame extruding the slope of inclined block, makes the piston disc sinking under the slope of inclined block and pressurizes the inside of pressure cabin, makes the pressure disc drive brake disc and exert pressure and brake, because the area of pressure disc in pressure cabin is pressed, far greater than the force area of piston disc in auxiliary cabin, makes piston disc can smaller pressure make it shift, can effectively alleviate the burden of oil pump.
