Abstract

This utility model relates to the field of tire forming equipment technology, specifically to a device for reducing the incidence of tire sidewall suspension buckling and folding. It includes two symmetrically arranged clamping assemblies, each comprising a mounting bracket. One end of the mounting bracket has a central shaft vertically mounted on it. A first ball bearing is fitted onto the central shaft, and a flexing arm roller is fitted onto the outer periphery of the first ball bearing. The mounting bracket has two flexing arms symmetrically arranged along its length, with the two flexing arms located on one side of the flexing arm roller. A plurality of second ball bearings are fitted onto the shafts of the two flexing arms. The device provided by this utility model for reducing the incidence of tire sidewall suspension buckling and folding can solve the problem of existing flexing arms easily causing tire sidewall suspension buckling and folding.
