Problems solved by technology

At present, the tire testing machines on the market can only realize the radial vertical load loading under the normal attitude of the tire, but cannot carry out radial loading under the attitude of the tire deflection at a certain angle and the attitude of the roll, which leads to the radial mechanical properties and stiffness of the tire. The test of characteristics is restricted, and the structure is relatively complex, large in size and high in cost

Abstract

The invention discloses a radial loading experimental device for a tire dynamic test. The radial loading experimental device for the tire dynamic test comprises a base frame and a radial loading mechanism which is fixedly arranged at the upper end of the base frame, wherein a tire to be tested is connected with the radial loading mechanism. The radial loading experimental device is characterized in that a tire turning mechanism is arranged on the radial loading mechanism, and an inclinable rotating drum device is arranged at the lower end of the base frame. When the test is conducted, the outer circumferential surface of the tire abuts against the inclinable rotating drum device. The radial loading experimental device has the advantages that the whole radial loading experimental device can test the radial mechanical feature and the rigidity feature of the tire in an upright posture, a deflection posture, a sideward inclination posture and a deflection and sideward inclination combination posture, the radial loading mechanism changes the radial displacement of the tire through cooperation between a lead screw and a transmission nut, and measures the value of the radial load in real time through a first force sensor, the radial load can be applied to the tire accurately and stably, and accuracy of the experimental result is guaranteed; in addition, the whole radial loading experimental device is simple and compact in structure and low in cost, and convenient to assemble and disassemble.

Description

technical field [0001] The invention relates to a tire performance testing device, in particular to a radial loading experimental device for tire dynamic testing. Background technique [0002] The tire radial load is an important factor affecting the radial deformation of the tire, which will directly affect the vehicle's power performance, economy, handling stability and braking performance. At present, the tire testing machines on the market can only realize the radial vertical load loading under the normal attitude of the tire, but cannot carry out radial loading under the attitude of the tire deflection at a certain angle and the attitude of the roll, which leads to the radial mechanical properties and stiffness of the tire. The test of the characteristics is restricted, and the structure is relatively complicated, the volume is large, and the cost is high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a r...
