Process and device for qualifying shock absorbers on spring-suspended vehicles, preferably of motor vehicles, provided with elastic tyres

摘要

In the process of this invention, the wheel of the landing gear with sinusoidal oscillations of constant amplitude is energized to a lying above the natural frequency frequency value, that is, accelerated but then delayed. During the deceleration phase that minimum sole force is measured, which occurs at the natural frequency of the system. The essence of the invention is that the minimum sole force approximated measured at the maximum frequency, and therefrom, and a ratio is formed from the measured at resonant frequency minimum sole force on the basis of which is then qualifies the quality of the landing gear shock absorption.; The proposed test device has a wheel support (1), a co-operating with this Erregereinhe ⁱ t, and an input coupled to an electronic measuring unit force sensor (5). Is its essence, that the Erregereinhe ⁱ t with lifting wedges (2) is provided with a rotating mechanism (3) can be moved in the horizontal plane, the wedges (2) partly on the wheel support (1) and partly between the two support beams (4) configured transmission structure are embedded. The one support of the two support bar (4) serves as a force sensor (5).
