Abstract
A wheel assembly comprises a drive shaft (18) and a spindle (16) which are drivingly splined together, and are axially secured together by a lock but (24). A snap ring (34) is secured in a groove (32) about the outerside circumference of the spindle (16), the snap ring (34) extending radially outwardly to engage an inner race (36) of a bearing (14) for axial securement of the spindle (16) with respect to the bearing. As the bearing is axially secured to a support member (17), the likelihood of loss of the spindle (16) and wheel (28) attached thereto through separation from a fractured axle shaft is minimized. <IMAGE>
Description
SPECIFICATION
Wheel assembly
This invention relates to wheel assemblies, and particularly, although not exclusively, to wheel assemblies comprising live spindles on drive shafts of vehicles.
In the prior art, a typical structure embodies a tapered roller bearing assembly mounted within a support member which is, in turn, fixed to a cross member or other base structure of a vehicle. Rotat ablyjournalled within the bearing assembly is a spindle on which a wheel is secured conventionally by nuts and bolts. The spindle has an internally splined portion through which a drive shaft having an externally splined mating portion extends. A lock nut is typically installed at the end ofthesplined portion of the drive shaft for axial securement of the spindle to the shaft.
It is common knowledge that splined drive shafts used for propelling vehicles undergo relatively high stresses. It is also common knowlege that such drive shafts may occasionally fracture, resulting in loss of a portion of the splined end of the shaft, along with the lock nut. As the spindle is generally axially secured to the shaft only by the lock nut, the forces applied to the spindle by the wheel are generally sufficient to result in separation of the sheel and spindle from the vehicle. The prior art structures have thus been unsatisfactory from a safety standpoint, in view of the potential wheel loss resulting from drive shaft failure.
According to the present invention there is provided a wheel assembly comprising a supporting member which supports a spindle by means of a bearing arrangement, the spindle being provided at its outboard end with coupling means for receiving a wheel, the coupling means being rotatable with the spindle relatively to the supporting member, retaining means being provided for retaining the spindle positively against axial movement in at least one direction with respect to the bearing arrangement whereby axial movement of the spindle with respect to the supporting member in the outboard direction is prevented.
The present invention thus provides a means for securement of wheel and spindle parts of a wheel assembly in the event of drive shaft failure and separation.
For a better understanding of the present invention and to show how it may be carried into effect, reference will now be made, by way of example, to the accompanying drawing which is a fragmentary cross section of a wheel assembly.
The wheel assembly 10 is mounted on a vehicle cross member 12 of a vehicle (not shown). The wheel end assembly 10 includes a support member 17 secured to the cross member 12 by bolts 19. A double tapered roller bearing assembly 14 is axially fixed within the annular shaped body of the support member 17. Journalled within the bearing 14 is a spindle 16 which extends axially outwardly of the wheel hub, and has a flanged portion 15 on which a wheel 28 is mounted. In the preferred embodiment shown, a drive axle shaft 18 extends through the spindle 16, the spindle 16 and drive shaft 18 being rotationally coupled together by splines 20 and 22.
This type of spindle is referred to as a "live spindle" as it rotates directly with the drive shaft. The drive shaft 18 has a yoke member 26 at the inboard end 40 thereof which, in the preferred embodiment shown, forms part of a universal joint coupling. At the opposite, or outboard, end of the drive shaft 18, a lock nut 24 is employed for axially securing the spindle and drive shaft together. The wheel 28 is affixed to the spindle 16 by bolts or rivet members 30 which also contain and support a brake drum 70.
It may be now appreciated that in a typical live spindle wheel end assembly, a fracture 46 along the path shown will result in loss of the lock nut 24 and of that portion of the drive shaft 18 positioned outboard of the fracture 46. Loss of the lock nut 24 permits the spindle 16 to freely shift or slide in the outboard direction relatively to the bearing 14, resulting in complete separation of spindle, drum, and wheel from the associated vehicle.
The improvement embodied in the illustrated wheel assembly 10 lies in a new structure for wheel retention shown at 50, which in the embodiment shown is positioned on the inboard side of the bearing 14. The structure 50 provides means for restricting axial movement of the spindle 16 upon fracture of the drive shaft. Thus, a groove 32 is provided in the outer circumference 42 of an inboard portion of the spindle 16. The groove 32 locates and contains a snap ring 34, the outboard side of which bears against the inner race 36 of the bearing 14.
Alternatively, the groove 32 could be positioned directly under the inner race 36 of the bearing 14 and an associated snap ring groove could be formed in the inner race 36. With either arrangement, the snap ring is engaged directly against some portion of the bearing 14.
In the preferred form as shown, however, an annular spacer 38 has a portion thereon which bears against the inboard side of the bearing inner race 36, the spacer 38 providing means by which the spindle 16 may be axially tightened via the lock nut 24 without binding the snap ring 34. Although the snap ring 34 is positioned between the spacer 38 and inner race 36, the arrangement described minimizes frictional forces on the snap ring, ensuring a greater useful life thereof. It will also be noted in the preferred form as shown, that a shoulder 60 will restrict axial outward movement of the bearing 14 in the event of drive shaft fracture. Thus is may now be fully appreciated that upon a fracture 46 of the drive shaft 18, and consequent loss of the lock nut 24, any outboard movement of the spindle 16 will be restricted by the interaction between the spindle 16, snap ring 34, and the bearing 14.
