Problems solved by technology

The stiffness of the tire is an important performance index of the tire. If the stiffness is too high, the impact force of the tire on the ground will be greater, and the friction between the tire and the ground will decrease, which will lead to problems of reduced comfort and increased braking distance.
Tires with too low stiffness do not support the car body enough, and the friction between the tires and the ground increases, resulting in reduced handling stability and increased fuel consumption.

Abstract

The invention relates to a fixing device for tire stiffness testing. The fixing device for tire stiffness testing comprises an installation base and a tire installation structure which is used for fixing a to-be-tested tire, the installation base is provided with a bottom plate which is horizontally arranged and a guide support which is vertically fixed on the bottom plate, and a guide groove which is vertically formed and has an upward opening is formed in the guide support; the tire installation structure comprises an installation plate and a guide block which is fixed on the installation plate, and the to-be-tested tire is installed on the installation plate; and the guide block is located in the guide groove, and the width of the guide block is the same as the width of the guide groove. According to the fixing device for tire stiffness testing, the requirements of tires with different sizes and different experimental equipment can be met.

Description

technical field [0001] The invention relates to automobile tire tests, in particular to a fixing device for tire stiffness tests. Background technique [0002] Tires are the only part that connects the vehicle to the ground and play a very critical role in the car. Tires not only support the car body, ease the impact of the road surface, but also play the role of driving and braking through the friction and braking force generated by contact with the ground. The stiffness of the tire is an important performance index of the tire. If the stiffness is too high, the ground impact force of the tire will be greater, and the friction force between the tire and the ground will decrease, which will lead to problems of reduced comfort and increased braking distance. Tires with too low stiffness do not support the car body enough, and the friction between the tires and the ground increases, resulting in reduced handling stability and increased fuel consumption. [0003] In order to ...
