Abstract:
The invention relates to a wheel (1) comprising a rim (2), a disc (3), a protective ring (4) with an outer surface (4a) and an inner surface (4b), and means (5) for fixing the ring (4) to the rim (2). To facilitate separation of the ring (4) from the rim (2), the protective ring (4) can be accessed from the inner surface (4b) through holes (8) made in the lip (2a) of the rim (2).
Abstract:
An assembly for supporting axles of different diameters in a wheel, in which the wheel has a hub with a bushing receiving portion having an interior surface of a first diameter. The bushing has a portion with an outer surface of a second diameter, somewhat smaller than the hub first diameter, to fit axially into the hub receiving portion and an axle receiving portion having an inner surface of a third diameter that accepts an axle of a corresponding diameter. The hub bushing receiving portion has a first seating on its interior surface and the bushing outer surface has a second seating. A fixing element in the bushing second seating expands radially of the bushing into the hub first seating when the bushing is inserted axially into the hub bushing receiving portion and locks the bushing to the hub.
Abstract:
A wheel (1) includes three parts: an outer rim (2), an inner rim (3), and a disc (4) joined by coach screws or stud bolts (18) directly screwed into the thickness of a wall (10) of the inner rim (3). The outer rim (2) is made from stamped light alloy plate, while the other parts are obtained by casting or other process. A portion of the outer rim (2) is compressed between the disc (4) and a portion of the inner rim (3).
