Problems solved by technology

As an indispensable part of the automobile air brake system, the hand brake valve is very important to its performance test. However, the traditional hand brake valve test equipment mostly adopts 0.4-level combined instrument display and semi-automatic operation. Factors have a great influence, so it is necessary to design a hand brake valve for automatic online detection equipment

Abstract

The invention discloses a hand brake valve on-line performance detecting table. According to the hand brake valve on-line performance detecting table, the output end of an air source is connected with the input end of a bigeminy part, the output end of the bigeminy part is connected with the input end of an air storage pot, the output end of the air storage pot is respectively connected with the input end of a precise pressure regulating valve and the input end of an electricity-air proportion valve, the control end of the electricity-air proportion valve is connected with a computer, and the output end of the electricity-air proportion valve is connected with a detecting device. The output end of the precise pressure regulating valve is connected with an air inlet of a two-position five-way electromagnetic valve, the control end of the two-position five-way electromagnetic valve is connected with the computer, and the output end of the two-position five-way electromagnetic valve is respectively connected with a first sliding table air cylinder, a second sliding table air cylinder and a third sliding table air cylinder. The hand brake valve on-line performance detecting table is efficient and accurate in detected result, the full-automatic on-line detecting device is used, and therefore the detection efficiency is greatly improved. The detection results are intelligently judged, and therefore man-made influences are reduced.

Description

technical field [0001] The invention relates to a device for testing the performance of vehicle parts, in particular to an online performance testing platform for a hand brake valve. Background technique [0002] The hand brake valve is an important device in the automobile air brake system. The hand brake valve is an important mechanism for the car to stay in place (including on a slope) for emergency stop and parking. As an indispensable part of the automobile air brake system, the hand brake valve is very important to its performance test. However, the traditional hand brake valve test equipment mostly adopts 0.4-level combined instrument display and semi-automatic operation. Factors have a great influence, so it is necessary to design a hand brake valve for automatic online detection equipment Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention proposes an online performance detection platform for a hand brake valve. [0004...
