Abstract

The invention relates to a run-flat support body for run-flat vehicle wheels. Said support body is typically embodied as a shell-shaped, metallic annular body (3) having an undulated supporting annular surface. The invention relates to a simple, effective method for producing one such annular body (3), according to which a rectangular blank (6) which is cut out of a strip of sheet metal is bent along the longitudinal side to form a ring and the open ends of the ring are interconnected by a material connection. The annular blank (7) thus produced is provided with the desired profile according to the pressure-rolling method, is provided with connecting elements (9), and cut open between the same.

Dependent claims

A method for producing a run-flat support body in the form of a shell-type, annular metal body with an undulated annular supporting surface for run-flat vehicle wheels, comprising the steps:

providing a rectangular metal blank with a long side adapted to the circumference of the annular body and a narrow side adapted to the width of the annular body,
Bending the metal blank along the long side to form an open ring,
Welding the ends of the open ring to form a closed annular blank,
Profiling the annular surface circumferentially to impart a cross-sectional undulated profile using a pressure rolling method,
Mounting detachably interconnectable connecting elements whose faces lie opposite one another to the profiled annular blank, and
Cutting the annular blank between the connecting elements to produce the mountable shell-type annular body with the undulated annular supporting surface.
