The tire fixing device is characterized in that a top plate, a movable plate, a hydraulic cylinder, two side plates, a bottom plate and four supporting columns are included, wherein the top plate, the movable plate, the two side plates and the bottom plate are rectangular; the four corners of the top plate and the four corners of the bottom plate are fixedly connected with the four supporting columns; the four corners of the movable plate are provided with four through holes for the supporting columns to pass, and the movable plate can slide on the four supporting columns; a base of the hydraulic cylinder is fixed to the movable plate, and the top of the hydraulic cylinder is fixed to the top plate; the tops of the two side plates are fixed to the two sides of the movable plate and are perpendicular to the movable plate; the bottoms of the two bottom plates are correspondingly provided with grooves used for fixing a wheel axle of the tire. The tire fixing device is simple in structure and convenient to transport, separation cost of the tire fixing device and a testing device is low, two kinds of rigidity in the vertical direction of the tire can be tested according to loading in different directions, and the two kinds of rigidity are important data sources of a tire mechanical property test.
Description
Technical field
The present invention relates to a kind of rigidity testing instrument, particularly relate to the fixing device of the tire in the test of a kind of mechanical elastic vehicle wheel tire vertical stiffness.
Background technology
Order tire vertical stiffness is the important component part of mechanics of tire characteristic, and the structural parameters of tire and mechanical characteristic decide the main rideability of automobile.Fixing device of the tire in the test of tire vertical stiffness is one of key equipment of testing tire performance.Existing fixing device of the tire complex structure, heaviness, and link together with testing apparatus, cost is higher.
Summary of the invention
Technical matters to be solved by this invention is for the defect in background technology, and the fixing device of the tire in providing a kind of tire vertical stiffness to test, utilizes Different Loading Method to measure two kinds of vertical rigidity of tire.
The present invention is for solving the problems of the technologies described above by the following technical solutions:
Fixing device of the tire in the test of tire vertical stiffness, comprises top board, movable plate, hydraulic cylinder, two side plates, base plate and four support columns;
