Description

Airbag deformation detection device of airbag shock absorber Technical Field The utility model relates to the technical field of air bag detection, in particular to an air bag deformation detection device of an air bag damper. Background An airbag cushion for a motorcycle is a device using an airbag as a main shock absorbing element, and unlike a conventional spring cushion, the airbag cushion absorbs and dampens impact and shock caused by a road surface by compressing or releasing gas. Advantages of the air bag damper for the motorcycle include convenient adjustment, adjustable damping effect according to requirements and good comfort. The bladder is made of a high strength, durable rubber composite material shaped like a ring or bladder structure, and is the primary load bearing and resilient element. The air bag can generate excessive deformation beyond the design range and even generate unrecoverable permanent deformation (such as bulge, dent and local expansion) under the conditions of high pressure, repeated compression and rebound, extreme road conditions or overload for a long time. Deformation is often a precursor to the impending rupture (e.g., crack, delamination) of the balloon. Sudden rupture of the air bag during running can cause instantaneous collapse of suspension, the motorcycle completely loses supporting and damping capacity, the vehicle is extremely easy to run away, and great threat is formed to the safety of a rider. It is therefore necessary to detect the degree of deformation of the balloon. The air bag damper comprises a spherical rubber air bag and two cover plates which are parallel to each other. The airbag shock absorbers with different structural sizes have different airbag deformations when bearing the same load, so that the airbag deformations of the airbag shock absorbers with different sizes are required to be measured when bearing different pressures, thereby guaranteeing the quality of the airbag shock absorbers.
