A sensor -load proportional valve that can display stress

Abstract

The invention relates to a load-sensing proportioning valve capable of displaying pressure. The load-sensing proportioning valve comprises a load-sensing proportioning valve body, an inlet oil pressure display structure and an outlet oil pressure display structure. The inlet oil pressure display structure and the outlet oil pressure display structure are additionally arranged on the load-sensing proportioning valve, brake oil pressure can be displayed in real time, and after the brake oil pressure is read, the adjusting convenience of the load-sensing proportioning valve in whole vehicle assembly and after-sales repair is simplified. By means of the load-sensing proportioning valve, the input-output oil pressure relation can be obtained, the input-output oil pressure relation of an actual vehicle can be directly and accurately determined, and the influences of various accumulative errors of all parts of a system on output oil pressure are avoided.

Description

technical field [0001] The invention belongs to the technical field of brake systems, in particular to a load-sensing proportional valve capable of displaying pressure. Background technique [0002] As the name suggests, the load-sensing proportional valve mainly senses the rear axle load dynamically, and adjusts the braking pressure of the rear axle in a timely manner according to the change of the rear axle load during the dynamic braking process, so as to achieve the purpose of adjusting the braking force of the rear axle. Avoid the locking of the rear axle prior to the front axle due to excessive braking force; the locking of the rear axle prior to the front axle will cause the vehicle to appear in an unstable working condition of tail flicking, which is prone to traffic accidents. [0003] As consumers have higher and higher requirements for vehicle safety, the safety configuration required by the automotive braking system must be continuously upgraded to meet customer ...

AI Technical Summary

Problems solved by technology

[0013] The purpose of the present invention is to propose an improved technical scheme for the current load-sensing proportional valve. Through this technical scheme, it can solve the problem that the load-sensing proportional valve in the prior art needs special auxiliary equipment when it is factory-assembled and adjusted, and the after-sales maintenance cannot be adjusted because there is no auxiliary equipment. Happening;

[0014] On the other hand, it can solve the situation that the pressure relationship between the front and rear axles cannot be adjusted accurately due to various accumulated errors in the existing technology
