Dual-rotation brake performance tester inspection bench

Abstract

The invention relates to automobile detection equipment used in the field of automobile industry, in particular to a dual-rotation brake performance tester inspection bench. In order to solve the problem that the measurement range is small and the actual measurement range cannot be reached, the problem that only static measurement can be carried out and dynamic measurement cannot be carried out and the problem that the actual application is difficult due to high control precision requirements and high part machining precision requirements although comprehensive calibration is achieved in the prior art, a full-automatic dual-rotation vehicle portable brake performance tester inspection bench is provided. A portable brake performance tester can be comprehensively calibrated, and all static and dynamic parameters can be automatically calibrated through one-time installation. A control system for dynamically simulating the brake acceleration change curve is simple in structure, the acceleration can be changed according to a specified magnitude only by changing the direction of an acceleration sensor of a calibration instrument, the real-time performance is high, and the matching degreebetween the simulated brake curve and the actual brake curve is extremely high. The mechanism is simple, and the part machining requirement is low. Dynamic unbalance vibration compensation is achieved, so that the whole machine is more stable in operation, the measurement data is more accurate, and the actual use and popularization performance is high.

Description

technical field [0001] The present invention relates to a kind of automobile detection equipment used in the field of automobile industry, more precisely, it relates to a double-rotation brake performance tester inspection platform. Background technique [0002] With the rapid development of my country's automobile industry, the occurrence of traffic accidents is becoming more and more frequent. One of the main reasons is that it is affected by the braking performance of automobiles. The quality of automobile braking performance directly affects the driving safety of vehicles, and only Only a qualified brake performance tester can accurately detect the braking performance of the vehicle, so the verification of the brake performance tester is the most important. [0003] The Chinese patent announcement number is "CN101173878A", and the announcement date is 2008.05.07. The name of the utility model is static and dynamic acceleration testing device, and the application number is...
