Problems solved by technology

[0005] It has been found that the service life of such existing rims may not be long enough, since the structural stresses present in the area where the side sections adjoin the middle section may lead to premature failure of the rim

Embodiment Construction

[0021] see figure 1 and figure 2 , which shows a wheel construction 10 comprising a rim 11 which, in use, receives a tire 14 on its tire side 12 . The position of tire 14 is only in image 3 is shown in .

[0022] The rim 11 is circular and in this case generally symmetrical, having an axially inner 16 and an outer 15 and an intermediate portion 18 between the axially inner 16 and the outer 15 .

[0023] The axially inner 16 and outer 15 are each formed with a flange 22 , a frusto-conical connecting surface 23 and side portions 19 , 20 between the intermediate portion 18 and each respective connecting surface 23 .

[0024] In use, each flange 22 and the adjoining portion of the connecting surface 23 form a seat for the bead of the tire 14 . On the inner radial side opposite the tire-receiving side 12 , the rim 11 is detachably or permanently fixed with a disc 13 , through which the wheel 10 can be mounted to the hub 17 by means of a plurality of fasteners 21 . In use, th...

Abstract

A wheel construction (10) includes a wheel rim (11 ) which in use, at a tyre side (12) of the rim (11 ), receives a tyre (14), the rim (11) being circular and having axially inner and outer portions (16,15), and a mid-portion (18) between the axially inner and outer portions (16,15), the mid-portion (18) including a circumferential well where the radius of the wheel rim (11 ) is a minimum, 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 the connecting 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 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 (24) of greatest radius, adjoining the flange (22), and the side part (20, 19) 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 frusto-conical region (28) at its end of greatest radius (26) adjoining the connecting surface (23), and the curved region (40) including first (41 ), second (42) and third (43) axially spaced circumferentially extending concave surfaces, when viewed from the tyre side (12) of the rim (11 ), the curved region (40) adjoining an end (29) of least radius of the frusto-conical region (28) and the mid-portion (18).

Description

technical field [0001] The present invention relates to wheel construction, particularly, but not exclusively, to wheel construction for agricultural vehicles or light construction machines or the like. Background technique [0002] Wheel constructions for agricultural vehicles and similar off-road vehicles are known which include circular rims forming respective axially inner and outer flanges, so Said inner and outer flanges each form a seat for a bead of a floating tire fitted to the radially outer or "tire side" of the rim. The type of wheel construction disclosed in the example of US-A-5560686 also includes a disc by which the wheel can be fixed to the hub of the vehicle, the disc is connected to the radially inner side of the rim, and the disc The disc and the rim are separable. However, the invention applies to wheels where the rim and disc are permanently joined together, eg by welding. [0003] In this specification, "high-passage wide-section tire" means a wide ...
