A tire blow-out simulation deflator comprises a hub with a deflating hole and a hard deflating tube. An inner end of the hard deflating tube is fixedly connected with the hub and is hermetically communicated with the deflating hole of the hub. A seal cap is arranged on an air outlet at the outer end of the hard deflating tube. An elastic pad for sealing the air outlet at the outer end of the deflating tube is fixed on the seal cap. One side of the seal cap is hinged to the outer end of a seal cap prop. The inner end of the seal cap prop is fixedly connected with the hub, a pressure bar, a pressure bar prop and a remote adjustable pressure bar forcing structure are arranged on the other side of the seal cap, and the inner end of the pressure bar prop is fixedly connected with the hub. The outer end of the pressure bar prop is hinged to the pressure bar. One end of the pressure bar is connected with the seal cap and presses the seal cap on the air outlet at the outer end of the hard deflating tube. The remote adjustable pressure bar forcing structure is arranged at the other end of the pressure bar. The vacuum tire blow-out simulation deflator is safe and reliable, can be disposed on a test vehicle for practical vehicle driving test, and has the advantages of simple structure and high simulation control precision.
Description
technical field [0001] The invention relates to an automobile safety test device, in particular to a tire burst simulation air deflation device during the automobile tire burst test. Background technique [0002] Blowout is an important cause of highway traffic accidents. Statistics show that in my country's expressway traffic accidents, tire blowouts account for more than 22%. Therefore, the tire blowout phenomenon of high-speed vehicles and its impact on vehicle handling stability and countermeasures are issues that relevant scholars and automobile companies have to face. [0003] The current tire blowout test mainly uses the following two methods to deflate the tire. One is to use the explosion of the detonator to realize the rapid deflation of the tire. Every time a test is done, a tire will be scrapped, which is very costly; the other is to use the electromagnetic valve to realize the rapid tire deflation. bleed, but the battery valve needs to be specially made. The ...
