Tire burst simulation rim and tire burst simulation method

Abstract

The invention relates to a tire burst simulation rim which is composed of a rim body, a deflation executor, a main valve base, an inflation air faucet, a resetting air faucet, a pilot pipeline, a threaded pipe sleeve and an electromagnetic pilot valve. The characteristic that the position around a rim groove of the rim body is suitable for containing a tire burst simulation deflation hole large enough in area is fully used, an air-controlled deflation main valve is designed through an electromagnetic membrane valve structure which is short in deflation path and large in deflation area, the area can be several times that of an existing simulation device, and the tire burst simulation rim can be used for tire burst simulation of a vehicle provided with double wheels. Because the deflation main valve is installed on the rim groove where a tire can be conveniently disassembled and assembled in a rear installing mode, the tire cannot freely disengage from the tire burst simulation rim, and a test vehicle will not be in danger even after a BMCS test fails.

Description

technical field [0001] The invention relates to a tire burst simulation technology for pneumatic tires used in vehicles, in particular to a tire burst simulation rim and a tire burst simulation method that can be repeatedly used in the test of the automobile tire burst monitoring and control system, and can ensure the safety of the vehicle after the test fails. . Background technique [0002] The tire blowout defined by GB / T30513-2014: "The air pressure of the inflated tire drops to the current ambient pressure within 750ms", but in most cases, the air pressure drop time is much shorter than 750ms, and the tire blowout defined by GB / T30513-2014 It can only be considered as the lowest intensity puncture. [0003] The tire burst simulation effect of the existing tire burst simulation device is limited. For example, in the tire blowout simulation device described in CN 102261999 B, the rim has holes in the circumferential direction to guide the main air pipe as a deflation ch...

AI Technical Summary

Problems solved by technology

When the tested BMCS (Burst Monitoring and Control System) fails, it will put the test vehicle in a dangerous state, and even cause disastrous consequences of vehicle crash

[0005] The existing tire blowout simulation technology still has problems such as large volume, complex structure, excessive increase in wheel weight, excessive external air release pipelines seriously affect the vehicle dynamic balance, and the extension of the tire blowout test device to increase the width of the rim, etc., which cannot be used for single Simulation of a flat tire on a vehicle with two wheels on each side of the axle
