Abstract

The invention discloses a test device of tire-bursting or rapid air leakage for an automobile. N numbered air-bleed holes are drilled on a rim and air in tires is communicated with an air-bleed control valve by respective gas-guide tube through the N numbered air-bleed holes. A control valve base at one side of a control cavity B is provided with a control valve body, an air-bleed cavity body and an air-bleed cavity cover; the control valve body is internally provided with I-shaped slide blocks and the control valve body positioned among the slide blocks is provided with a air leakage port; one side of the slide block is communicated with the control cavity B and the other side thereof is communicated with the control cavity A; the air leakage cavity body is provided with N-1 numbered air leakage holes which are respectively communicated with N-1 numbered gas-guide tubes; the control valve base is provided with the air-bleed holes in a radial direction, one end of which is communicated with the n air-guide tube and the other end of which is communicated with the control cavity B by a two-phase three-way magnetic valve; and the magnetic valve realizes communication between the control cavity B and the n air-guide tube or between the control cavity B and atmosphere and is connected with a remote control switch. The invention adopts the remote control switch and the two-phase three-way magnetic valve with small flow to control opening/closing of big flow, thereby finishing the test of the tire-bursting or the rapid air leakage for the automobile.

Description

technical field [0001] The invention relates to a tire burst or rapid air leakage test device, in particular to an automobile tire burst or rapid air leakage test device. Background technique [0002] Car tire blowout or rapid air leakage is one of the most important factors leading to car accidents. Due to tire blowout or rapid air leakage, the vehicle is seriously unstable. It is necessary to ensure that the vehicle brakes and stops under the premise of stability. The emergency auxiliary braking system with automatic braking stability control function has become one of the hot spots in the research of automobile braking safety performance. The development of the tire burst emergency auxiliary braking system and the matching test with related vehicles are inseparable from the real vehicle tire burst or rapid air leakage test, and the test device that is measurable and controllable and conforms to the actual situation of the tire burst during the driving process of the vehic...
