A manually adjustable wheel for, e.g. a tractor, com-prising a generally octagonal disc having four longer sides and four shorter sides, the rim having lugs to which the disc is bolted, the rim/disc bolts being arranged in pairs on the shorter sides of the disc only.
Description
5~7~
This invention relates to a manually adjustable wheel for a high horse power vehicle such as an agricultural tractor.
It is known to provide agricultural tractors with manually adjustable wheels whereby the track, i.e. the spacing between the driven wheels of the tractor, may be adjusted to suit its use in differing agricultural situations where for example differing widths of rows of crops have to be traversed by the tractor. Such known manually adjustable wheels usually comprise a rim detachably secured to a disc which is itself detachably secured in conventional manner to a hub at the end of a drive sha~t. The means for de-tachably securing the rim to the disc usually comprises a plurality of lugs spaced apart circumferentially around the radially inner surface of the rim.
The disc usually comprises a generally circular steel ele-ment havingascalloped periphery, the apices of the scallops providing circumferentially spaced apart portions of the disc adjacent the rim which are bolted to the lugs.
It is an object of the invention to provide a manually ad-justable wheel wherein the amount of material used in the disc is optimized having regard to the required strength of the wheel.
,, ~53~9 According to the invention we provide a manually adjustable wheel for a vehicle, e.g. a tractor comprising a rim to receive a tire; a plurality of channel-shaped fixing lugs spaced apart around the radially inner periphery of the S rim, the lugs being arranged in pairs with the circumferen-tial spacing between the lugs of each pair being less than the circumferential spacing between adjacent lugs of adja-cent pairs, the lugs having flanges which overlie, and are welded to the rim thus fixedly to secure the lugs to the rim; a disc of uniform thickness for connection to-a hub of the vehicle; the disc having substantially the shape of a square with the corners cut off so that the disc has an irregular octagonal shape having four longer sides and four shorter sides arranged alternately around the periphery of the octagon, each shorter side being juxtaposed against a pair of lugs; and bolt means detachably securing the disc to the lugs, the disc and lugs being arranged so that the disc may be selectively secured to the lugs in either of two positions, the bolt means being located along the shorter sides of the disc only and, at each of said shor-ter sides comprising two bolts each passing through the disc and through one of the lugs of a pair of lugs juxta-posed to said shorter side.
The features of the invention will become apparent from the following description given herein solely by way of example with reference to the accompanying drawings wherein:
FIGURES 1 and 2 are axial viewsof manually adjustable wheels constructed in accordance with the prior art;
FIGURE 3 is an axial view of a manually adjustable wheel constructed in accordance with a first embodiment of the invention;
FIGURE 4 is a cross-sectional view on the line 4-4 of F igure 3;
~5~37~
FIGURE 5 is an axial view of a manually adjustable wheel constructed in accordance with a second embodiment of the invention; and FIGURE 6 is a cross-sectional view on the line 6-6 of Figure 5.
Figures 1 and 2 of the drawings show manually adjustable tractor wheels as constructed by prior art methods. Thus, referring to Figure 1, it will be seen that the wheel rim 10 is provided on its radially inner surface with a set of eight equi-distantly spaced apart lugs 12 welded to the rim. The disc 14, which is detachably secured to the rim lugs 12 by means of bolts 16, is of generally circular configuration but has a scalloped periphery with the apices of the scallops providing portions adjacent the rim which are boltable to the lugs.
Figure 2 of the drawings shows a similar construction of wheel wherein six circumferentially spaced lugs 112 are provided on the rim 110 to which six corresponding por-tions of a generally circular disc 114 are boltable.
In each case the variation in track is obtained by (1) varying the surface of the disc which is in contact with the hub and (2) varying the ends of the lugs against which the disc abuts.
In each of the constructions shown in Figures 1 and 2 the construction of the disc 14 is extremely wasteful of metal since it is generally ~ircular and is usually produced as a steel stamping out of a square or rectangular blank.
Referring now to Figures 3 and 4, these show a first em-bodiment of the invention. There is a disc 50 secured to a rim 51. The disc has a central planar portion or nave 52 and a conical portion 53 leading to a portion 54 which , 3'7~
is perpendicular to thé rotary axis 55 of the wheel. The disc is made from a square blank and as shown in Figure 3 is generally octagonal in shape having four longer sides 56 which alternate, around the periphery of the disc, with shorter sides 57. It will be noted that the longer sides 56 are slightly concave towards the centre of the disc while the shorter sides 57 are convex towards the centre of the disc. It will be seen from Figure 4 that the disc is of uniform thickness.
Secured to the radially inner periphery of the rim are eight lugs 58 which are arranged in pairs with a circum-ferential ~pacing between the lugs of each pair being less than the circumferential spacing between adjacent lugs of adjacent pairs. These lugs are generally of top hat sec-tion and provide, referring to one of the lugs, a channelhaving sides 59, a base 60 and flanges 60a. The flanges 60a are welded to the rim and the channel in the lug ex-tends generally parallel to the rotary axis of the wheel and receives a bolt 61 which passes through the lug and through an aperture 62 in the disc. Each bolt has a head 63 and is prevented ~rom turning by a rib 64 under the head which fits in the channel of the lug as shown in Figure 4, and carries a nut and washer 65 and 66 respec-tively. It will be noted that the apertures 62 and the bolts 61 are located on the shorter sides only of the disc.
Variation in track of a vehicle having wheels as shown in Figures 3 and 4 is obtained either by reversing the disc 50 so that it diverges towards the left rather than the right in Figure 4 and/or, by arranging the part 54 of the disc at one side or the other of the lugs 58.
Referring now to Figures 5 and 6, these show a second em-bodiment of thé invention comprising a disc 70 and a rim 71. As shown in Figure 5, the disc has been made from a square blank and has four longer sides 72 and four shorter 37~
sides 73 so that it has the shape of an irregular octagon.
It will be noted that th longer sides 72 are slightly concave towards the centre of the disc while the shorter sides 73 are slightly convex relative to the centre of the disc.
The rim is secured to the disc by lugs and bolts as before.
The lugs are indicated at 74, are arranged in pairs as described in relation to Figures 3 and 4, and as shown in Figure 6 are of top hot cross-section having a base 75, side walls 76 and flanges 77. The flanges 77 are welded to the rim so that the channels in the top hat section ex-tend perpendicular to the rotary axis of the wheel. Each lug is strengthened by a gusset plate 78.
Still referring to Figure 5, the disc 70 has a central portion 79 adapted to be secured to the hub of a vehicle via apertures 90 and bolts or studs (not shown). It then has a portion 80 which is perpendicular to the rotary axis of the wheel but displaced from the portion 79. Outwardly of the portion 80 is a conical portion 81 which then leads to a portion 82 perpendicular to the rotary axis of the wheel. The portion 82 provides the shorter sides 73.
The disc is secured to the wheel by bolts 83 which have squared portions 84 on their shanks to engage in square section holes 85 in the walls 76 of a lug, each bolt having a threaded portion 86 to receive a nut 87 and washer 88.
It will be noted that the bolts 83 pass through apertures 89 in the disc and that these apertures are located in the shorter sides 73. Variation in track of a vehicle having wheels as shown in Figures5 and 6 is obtained as before either by reversing the position of the disc and/or by changing the side wall of the lug against which the por-tions 82 of the disc abut.
~53~
It will be seen that the invention provides two embodiments of wheeIs, specially for tractors, in which the discs can be made from square blanks with very little waste in material as compared with the considerable waste in material involved where the blanks are circular as shown in Figures 1 and 2 which relate to the prior art.
