Moulded part for connection to a rim well of a wheel and rim well which is connected to a moulded part

摘要

There is described a shaped object adapted for being connected with a rim at a point located inside the rim well (7), having a contact surface (2) intended to rest on the rim well. It is provided according to the invention that the contact surface (2) intersects each of a set of mutually parallel first planes (3) along a curved curve (5), which is not merely an arc of a circle and whose distance from a second plane (6), that subdivides the contact surface (2) and that extends perpendicularly to the first planes (3) increases with a decreasing growth rate, at least in average, at least on one side of the second plane (6).
