Abrasive paper polishing detection device for tire force and torque detection

Abstract

The invention discloses an abrasive paper polishing detection device for tire force and torque detection. The abrasive paper polishing detection device comprises a base used for supporting the ground,a supporting column is vertically arranged at the upper left end of the base, a guiding clamping block is arranged at the upper end of the supporting column, and a moving base is arranged in a U-shaped sliding groove in the upper end of a first pressing disc in a sliding fit mode. A limiting block embedded into a guide groove in the surface of the moving base is arranged on the inner wall of a U-shaped groove of the first pressing disc, a grinding wheel mechanism used for grinding abrasive paper is installed at one end of the moving base, and a positioning assembly used for containing the abrasive paper is installed at the upper end of the base. The positioning assembly is electrically connected with a control panel arranged on the supporting column. The device is designed for overcomingthe defects of an existing device, abrasive paper polishing is uniform, in the polishing process, data can be collected to obtain the friction coefficient, good correlation is achieved, and meanwhilethe beneficial effects of being simple in equipment, low in cost and the like are achieved.

Description

technical field [0001] The invention relates to the technical field of tire manufacturing, in particular to a sandpaper grinding detection device for tire force and moment detection. Background technique [0002] The coefficient of friction is defined as the ratio of the friction force that prevents the relative motion of two objects to the normal force acting on the contact surface of the two objects. Tire friction coefficient is one of the main performance indicators of tires, and it is also an important parameter for force and moment detection. In the force and moment detection, the tire acts on the surface of the sandpaper, and the accuracy and stability of the friction coefficient measurement of the sandpaper directly determine the reliability of the tire detection data. During the force and moment testing process, the service life of sandpaper is generally one year. In use, the coefficient of friction goes through three processes: reduction period-stabilization perio...

Problems solved by technology

[0003] In option 1, it is not easy to manually pull the tensile machine at a constant speed, so the data repeatability is poor and inaccurate; in option 2, as the tire wears out, the longitudinal force increases under the same conditions, and the friction coefficient also increases, which is different from the actual sandpaper friction coefficient. Decrease with use

At the same time, there is no special equipment in the market for pre-grinding sandpaper
