Embodiment Construction

[0023] refer to figure 1 and figure 2 , which shows a wheel construction 10 including a rim 11 that, in use, receives a tire 14 on its tire side 12 . The location of the tire 14 is only shown in FIG. 3 .

[0024] The rim 11 is circular, and in this case asymmetrical, with an axial inner 16 , an axial outer 15 and a middle 18 between the axial inner 16 and the axial outer 15 .

[0025] Both the axially inner portion 16 and the axially outer portion 15 are provided with a flange 22, a frusto-conical connecting surface 23 and side portions 19, 20 between the central portion 18 and the respective flange.

[0026] In use, each flange 22 and the adjacent portion of the connecting surface 23 constitute a seat for the bead of the tire 14 .

[0027] Reference will now be made to Figure 4 The configuration of the axially outermost 15 of the rim 11 (ie, the portion of the axially outermost rim 11 of the vehicle on which the wheel 10 is mounted in use) is described in detail.

Abstract

A wheel construction (10) includes a wheel rim (11) which in use receives a (tyre 14), the rim (11) having axially inner and outer portions (16, 15), and a mid-portion (18) between them, and each axially inner and outer portion (16, 15) providing a flange (22), a connecting surface (23) adjoining the flange (22) and extending axially towards the mid portion (18), the flange (22) and a part of theconnecting surface (23) providing a seat for a bead of the tyre (14), and there being a side part (19, 20) between the connecting surface (23) and the mid portion (18), and wherein for at least one of the inner and outer portions (16, 15), the connecting surface (23) is a frusto-conical having an axial end (24) of greatest radius and an axial end (25) of least radius, the connecting surface (23),at its axial end of greatest radius (24), adjoining the flange (22), and the axial end (25) of least radius adjoining a circumferentially extending convex surface (26) which extends radially outwardly of the wheel axis A beyond the end (25) of least radius of the adjoining frusto-conical connecting surface (23), and the side part (19, 20) of the at least one of the axially inner and outer portions (16,15) including a generally frusto-conical region (28) and a curved region (40), the curved region (40) including first and second axially spaced circumferentially extending concave surfaces (41, 42), and the curved region (40) adjoining the end of least radius of the frusto- conical region (28) and the mid-portion (18).

Description

technical field [0001] The present invention relates to a wheel construction, and more particularly, but not exclusively, to a wheel construction for agricultural vehicles or light construction machines and the like. Background technique [0002] Wheel constructions for off-road vehicles such as agricultural vehicles are known, such wheel constructions include circular rims forming respective axial inner and outer flanges, which respectively constitute a The seat on the tire bead of a floating tire that mates with the radially outside or "tire side" of the rim. In the example of US-A-5560686 a wheel construction is disclosed which further comprises a disc by which the wheel can be fixed to the hub of the vehicle, the disc being connected to the radial direction of the rim inside, and the disc is separable from the rim. However, the invention is applied to wheels in which the rim and the disc are permanently joined together, eg by welding. [0003] In this specification, "...
