A special wheel rim with weight-reducing grooves

Abstract

This utility model discloses a special wheel rim with weight-reducing grooves, relating to the field of automotive wheel rim technology. It includes a connecting disc assembly, a connector fixedly connected to one side of the connecting disc assembly, and a first weight-reducing groove on the outer surface of the connector. A wheel rim assembly is fixedly connected to the end of the connector, and a combined weight-reducing groove is formed on the outer surface of the wheel rim assembly. This utility model utilizes the stability of a triangle in the middle of the connector to prevent easy deformation of the connector, thus reducing its weight and consequently the weight of the wheel rim. Furthermore, a U-shaped second weight-reducing groove is formed on the outer wheel rim, and a third weight-reducing groove is formed on the side of the outer wheel rim. By creating the second and third weight-reducing grooves in non-stress-concentration areas, this design not only ensures the structural strength of the wheel rim assembly but also reduces its weight.
