Abstract

The invention discloses a tire stiffness testing device used for measuring the vertical stiffness, the longitudinal stiffness and the lateral stiffness of a tire and completing measurement of coupling stiffness. The tire stiffness testing device comprises a vertical loading device, a lateral loading device, a longitudinal loading device, a base, a rack, a roll axis, a connecting piece, expansion connecting sleeves, a first plane connected with the base through a longitudinal steel rail, and a second plane connected with the first plane through a transverse guide rail; the connecting piece, the first plane and the second plane are each provided with a linear displacement sensor; the roll axis is connected with the connecting piece through the two expansion connecting sleeves; the connecting piece is provided with a six-component-force sensor; through holes matched with two guide rails of the rack are formed in the connecting piece. The tire stiffness testing device is simple in structure, reasonable in design and capable of measuring acting force in all directions of the tire, linear displacement sensors of the loafing devices can measure displacement of the tire in all the directions, and the stiffness, in all the directions, of the tire and the coupling stiffness of the tire can be obtained through calculation.

Description

technical field [0001] The invention relates to the field of tire performance testing, in particular to a tire stiffness testing device. Background technique [0002] Tire stiffness is an important parameter for studying the mechanical properties of tires, and the measurement accuracy of this parameter plays a decisive role in studying the mechanical properties and structural parameters of tires. [0003] The current tire stiffness test device generally only loads the tire in a single direction, and measured the stiffness data of the Liaoning station in a single direction. However, in actual situations, it is generally subjected to multi-directional loads, so there is an urgent need for devices to test the stiffness characteristics of each direction and coupling stiffness characteristics, but such devices are rare in China. Contents of the invention [0004] The main technical problem to be solved by the present invention is to overcome the defects of the prior art and pr...
