Abstract

The invention relates to a testing device for tire dynamic impressions, which comprises a transparent plate, a seat body, a first driving mechanism and photographic equipment, and is characterized in that pressure sensing paper is arranged on the transparent plate; wherein a wheel fixer for fixing a wheel is arranged on the seat body; the first driving mechanism is connected with the seat body and is used for driving the seat body to move along a set path, so that the wheel fixer drives the wheel to roll on the pressure sensing paper; and the photographic equipment is positioned below the transparent plate and is used for shooting tire marks generated on the pressure sensing paper. According to the invention, the problems that only the static impressions of the tire can be measured and the change of the grounding shape, the grounding area and the stress distribution under the dynamic change of the tire in the vehicle driving process cannot be simulated to the greatest extent in the related technology can be solved.

Description

technical field [0001] The present application relates to the technical field of tire testing, in particular to a testing device for tire dynamic marks. Background technique [0002] With the advancement of tire production technology and the continuous improvement of tire performance requirements, the impact of tire contact area and stress distribution on tire adhesion performance, wet skid performance, handling performance and tire internal structure design is becoming more and more important. [0003] In some related technologies, a tire is placed on a pressure blanket and a vertical load is applied to read the static tire impression by means of a pressure sensor and a pressure-sensitive film and other testing methods. [0004] The above-mentioned solutions usually only measure static tire footprints, and cannot simulate to the greatest extent the changes in ground contact shape, ground contact area, and stress distribution under dynamic changes of tires during vehicle dri...
