Problems solved by technology

This can cause problems when mounting such tires, specifically when the rim well sidewalls are at angles close to the standard minimum with respect to a plane perpendicular to the wheel axis, one or both beads may not be aligned when initially inflated not directly on the rim

Embodiment Construction

[0026] Referring to the drawings, a wheel structure 10 typically used for tractors, industrial machinery, etc. comprises a rim 12 on which, in use, a tire 13 (a portion of the tire is shown in phantom in FIG. 2 ) is mounted; The wheel structure 10 may be connected to a hub or axle of a tractor, industrial machine or the like via the spokes.

[0027] The spokes 14 include a plurality of openings 15 for receiving bolts or other fasteners for this purpose; Figure 4 In one example, the rim 12 is permanently affixed to the spokes 14 by welding, but in other examples, the rim 12 may be attached to the rim 12 by fasteners, as has been widely accepted in the art, which may be The axial position of the rim 12 is enabled to be varied relative to the hub or axle of the vehicle, thereby varying the distance between a pair of wheels rotating about a generally common axis A.

[0028] The rim 12 is circular in shape with a radially inner surface 17 and a radially outer surface 18 ;

Abstract

A wheel construction (10) includes a wheel rim (12) which in use, receives a tyre (13), the rim (12) being circular and having axially inner and outer portions (19, 20) each of which provides a flange (24) which in use provides a seat for a bead (26) of the tyre (23), and the wheel construction (10) including a mid-portion (29) between the inner and outer portions (19, 20), and side parts (30), connecting the mid (29) and outer portions (19, 20), the mid-portion (29) including a circumferential well (28) where the radius of the wheel rim (12) is a minimum, at least one of the side parts (230) including a plurality of curved regions (38, 39), the plurality of curved regions (38, 39) each being immediately adjacent to each other whereby the side part (30) is continuously undulate. Each curved region (38, 39) provides at least a further two circumferential wells (40, 41). For each adjacent two curved regions, there is an effective angle between a plane normal to the axis of the wheel and a line struck tangentially at a point of inflection between the two curved regions at a tyre side of the rim, of between 25 DEG and 45 DEG .

Description

technical field [0001] The present invention relates to a wheel structure, in particular but not exclusively to a wheel structure for tractors and the like. Background technique [0002] For example, a wheel construction is known from US-A-5560686 comprising a circular rim provided with corresponding axially inner and outer rims, each of which is provided with a There are standoffs for the bead of a tire mounted radially outside or "tire side" of the rim. In the example of US-A-5560686, the wheel structure also includes spokes by which the wheel can be fixed to the hub of the tractor, the spokes are attached to the radially inner side of the rim, and the spokes are detachable from the rim. [0003] The rim has a generally centerable middle portion where a central well is provided on the side of the tire; furthermore, the rim includes side portions extending radially outward between the central well and the rim ( side part), each of which includes a pair of flat surfaces (w...
