Problems solved by technology

[0002] In the construction vehicle industry, most manufacturers use special tire test benches to test the hysteresis loss resistance performance of tires. However, in the existing tire test benches, tires are analyzed under static conditions, and the test results are not accurate. Accurate; even if the force analysis under the rotating platform is used, the connection between the drive shaft and the tire is integrated, and it is difficult to disassemble when the tested tire is damaged or the model of the tested tire is replaced, which seriously consumes man-hours

Abstract

The invention provides a test bench for mechanical performance testing of a tire. The test bench comprises a test bench support frame, a lift transmission mechanism, a rotary transmission mechanism, a first support plate, and a pressure sensor. The lift transmission mechanism consists of a portal frame, two guide rails, and a hydraulic cylinder; the two guide rails are arranged on the support plate vertically; chutes are formed in the side support walls of the portal frame; sliding blocks are arranged at the side walls of the two guide rails; and on the basis of cooperation of the chutes and the sliding blocks, the rotary transmission mechanism can move to be lifted to drive the portal frame to make lifting reciprocating motion at the guide rails. The rotary transmission mechanism consists of a drive shaft, a drive motor, and a hub fixation unit; the hub fixation unit includes a first fixed plate and a second fixed plate that sleeve the drive shaft for fixing the hub; a protruding limiting part is arranged at the drive shaft; the first fixed plate is provided with a recessed limiting part cooperating with the protruding limiting part for limiting; and the drive shaft includes a first rotation shaft and a second rotation shaft that are in reverse threaded connection.

Description

technical field [0001] The invention relates to the field of tire testing, in particular to a tire mechanical performance test bench. Background technique [0002] In the construction vehicle industry, most manufacturers use special tire test benches to test the hysteresis loss resistance performance of tires. However, in the existing tire test benches, tires are analyzed under static conditions, and the test results are not accurate. Accurate; even if the force analysis under the rotating platform is used, the connection between the drive shaft and the tire is integrated, and it is difficult to disassemble when the tested tire is damaged or the model of the tested tire is replaced, which seriously wastes man-hours. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a tire mechanical performance test bench: including a test bench support frame, a lifting transmission mechanism, a rotation tr...
