Problems solved by technology

When the piston moves back and forth in the valve body, it is easy to cause wear and tear. Although the existing valve body can meet the needs of hydraulic braking, the structure of the valve body is not optimized enough, and the size relationship between the valve cavity, the oil inlet hole and the oil outlet hole is unreasonable. , so that the wear of the piston is more serious, and the hydraulic oil is likely to cause losses when transmitting power; under ordinary braking, the temperature in the valve body will rise, resulting in an increase in pressure. On the one hand, it can dissipate heat, and on the other hand, it can improve the structural strength of the valve body, but this solution will increase the volume of the valve body, increasing the difficulty and cost of production
[0003] In terms of production, the design of the production process is also particularly important, because during the machining process, the internal temperature of the workpiece will rise, which will easily cause deformation. If it is not handled properly, it will directly affect the quality of the workpiece, especially the oxidation treatment. There are many variable factors and improper control, and the ideal oxide layer cannot be formed

Abstract

The invention particularly relates to a valve body of an automobile hydraulic brake valve and a production process thereof, belonging to the technical field of automobile spare parts, the valve body includes two communicating ports, a conical end face is arranged at one of the ports of the valve body, four sets of radial through holes are arranged in the middle of the valve body, which are a radial through hole I, a radial through hole II, a radial through hole III and a radial through hole IV, the radial through hole I and the radial through hole II are perpendicular to and intersect with each other, the radial through hole III and the radial through hole IV are perpendicular to and intersect with each other, the wall thickness of the valve body is h, the inner diameter of the valve bodyis R, the radial through hole I, the radial through hole II, the radial through hole III and the radial through hole IV have the same aperture r, and r<h<2r<R<3r. The valve body has the advantages ofsimple structure, light weight, high structural strength, long service life, and can provide stable oil pressure, so that the braking is faster and more sensitive.

Description

technical field [0001] The invention belongs to the technical field of automobile spare parts, and relates to a brake valve, in particular to a valve body of an automobile hydraulic brake valve and a production process thereof. Background technique [0002] Automobile braking adopts hydraulic control, which can obtain more stable braking force, and has quick response, sensitivity and labor saving. When the piston moves back and forth in the valve body, it is easy to cause wear and tear. Although the existing valve body can meet the needs of hydraulic braking, the structure of the valve body is not optimized enough, and the size relationship between the valve cavity, the oil inlet hole and the oil outlet hole is unreasonable. , so that the wear of the piston is more serious, and the hydraulic oil is likely to cause losses when transmitting power; under ordinary braking, the temperature in the valve body will rise, resulting in an increase in pressure. On the one hand, it can...
