Abstract

The invention provides a tread pattern rigidity and friction characteristic testing platform and relates to the field of tire performance testing devices. The testing platform comprises a base, a support frame, a simulation pavement driving device, a sample fixture, a pressure detection device and a pressurizing device, wherein the support frame and the simulation pavement driving device are arranged on the base, and the simulation pavement driving device is used for clamping a simulation pavement and driving the simulation pavement to horizontally move; the sample fixture is arranged on a pressure output end of the pressurizing device, the pressurizing device is arranged on the support frame above the simulation pavement driving device and is used for pressurizing the sample fixture to generate a required pressure between a sample and the simulation pavement; the pressure detection device is arranged between the sample fixture and the pressurizing device and is used for transmitting the pressure and measuring stress data of the sample in real time; the support frame is used for supporting and fixing the pressurizing device. The tread pattern rigidity and friction characteristic testing platform has the advantages that the structure is simple, the use is convenient, the cost is low, and the measured data is accurate.

Description

technical field [0001] The invention relates to the field of tire performance testing devices, in detail, it is a tire pattern stiffness and friction characteristic testing platform with simple structure, convenient use, low cost and accurate test data. Background technique [0002] We know that the service life and friction characteristics of tires are mainly determined by the pattern part of the tire in contact with the road surface, but there is no device for testing the stiffness and friction characteristics of the tire pattern in the existing testing machine, and the stiffness and friction characteristics of the tire pattern It is also an important factor affecting the braking performance of tires on wet and dry ground. At present, tire manufacturers usually adopt the traditional existing pattern design form for their tire patterns; for the designed new tire patterns, they are directly put into use without performance testing; the new tire patterns will greatly affect t...
