Technical Field

[0001] The utility model relates to the technical field of aviation tire tread rubber friction testing, in particular to aviation tire multi-angle friction force detection equipment. Background Art

[0002] Aviation tires, commonly known as aircraft tires, are the only parts of an aircraft that come into contact with the road surface. They support loads, transmit braking force, driving force, and steering force during takeoff and landing, and are directly related to flight safety.

[0003] Existing multi-angle friction testing equipment for aircraft tires, such as the one disclosed in Chinese utility model patent application number CN202322126801.X, uses an electric telescopic rod to control the movable rod to first retract and then extend and recover. A fixed column located on the outer wall of one end of the movable rod can squeeze the convex portion of the first connecting tube and the concave portion of the second connecting tube, allowing the first connecting tube, the second connecting tube, the sleeve and the friction test assembly to rotate counterclockwise 72 degrees as a whole, thereby realizing the replacement of multiple friction plates. The friction coefficients of the outer surfaces of the five annularly distributed friction plates are all inconsistent, which can simulate a variety of landing ground conditions and facilitate the testing of tread rubber friction tests of aircraft tire tread rubber samples under various ground conditions.
