Abstract

The invention discloses a device for a tire burst test, comprising a wheel. A wheel hub is provided with a deflation port, a deflation tube is welded at the deflation port, and the deflation tube is provided with an electromagnetic valve; a rotating bearing is arranged outside a wheel shaft, and an insulating layer is arranged outside the rotating bearing; the wheel shaft and the anode a vehicle power source are connected through a switch circuit, the anode of the electromagnetic valve is connected with a circuit of the rotating bearing, and the cathode of the electromagnetic valve is connected with a circuit of the wheel hub. The device is additionally provided with an accessory device on a tire wheel hub of a conventional automobile and uses the electromagnetic valve as a control unit to deflate the tire so as to achieve the test effect same as the tire burst without damaging the tire, thereby saving the cost and being favorable for repeated tests.

Description

technical field [0001] The invention relates to a vehicle test device, in particular to a tire burst test device. Background technique [0002] The importance of tires to cars is self-evident. In daily life, due to tire aging, excessive wear, abnormal tire pressure, tire trauma and other reasons, tire blowout accidents occur frequently, ranging from scrapping the vehicle to jeopardizing the lives of drivers and passengers. According to incomplete statistics, 42% of highway traffic accidents are caused by blown tires, and the death rate of blown tires at a speed of more than 160 kilometers per hour is nearly 100%. Blowout has become the "number one killer" of highway traffic accidents. Therefore, each major tire manufacturer carries out experimental research on the problem of tire blowout, and develops run-flat tires or devices that prevent blowout. For example, the Chinese invention patent No. 200510063728.X discloses a kind of run-flat tire, including a carcass composed ...
