Abstract

The invention relates to a tire testing machine which comprises a fixing device and a testing device, wherein the testing device is in contact with a tire on the fixing device through a loading device. The tire testing machine has the technical effects that (1) the tire is fixed on the fixing device, the testing device is in contact with the tire through servo system loading, and tire puncture, impression, vertical stiffness and other tests can be realized; (2) the loading device and the testing device are positioned in a foundation pit, so that high loading force can be provided for the testing device; (3) the tire is provided with a protective fence at the exposed part of the back of the testing device, so that potential risk of the test is avoided; (4) an isolated warning fence is arranged at the periphery of the foundation pit, so that an operator is prevented from dropping into the foundation pit due to slip.

Description

technical field [0001] The invention belongs to the field of machinery and relates to a tire testing machine. Background technique [0002] The traditional tire testing machine is fixed for the test bench and the test device, and the tire is loaded onto the test device by a servo device for puncture and impression tests. [0003] In the prior art, there is no special test device for testing the strength, footprint, vertical stiffness and sinkage of OTR tires. Contents of the invention [0004] In order to solve the difficult problems of testing the strength, footprint and vertical stiffness of engineering tires, the invention provides a tire testing machine. [0005] The technical scheme adopted in the present invention is: [0006] The tire testing machine includes a fixing device, a testing device, and a control device. The testing device is driven by a loading device to load the tire on the fixing device. [0007] Preferably, the loading device includes a servo motor...
