Reifen-/Felge-Einheit für LKW

摘要

A wheel assembly comprising a radial ply tyre (P) and a rim (J) with the outside of each seat (20) having an edge (R) formed from part of a truncated cone (23) generally making an angle to the axis of rotation of 20-60 degrees , joined inside to the seat by a S-shaped part and extended outward by a portion of a cylinder (25) itself extended by a lip (26). The width of the rim (A) is at least equal to 0.65 times the maximum width of the tyre inflated to working pressure. The height (H) of the lip is smaller than a normal rim of the same width and is a linear function of the width such that H=a.A where H = height; A = width and a = 0.105 to 0.115.
