Description
STUB AXLES
The present invention relates to stub axles and in particular to tubular stub axles for motor vehicles.
According to one aspect of the present invention a stub axle comprises a tubular member adapted to be located in fixed relationship with respect to a vertical link of a vehicle suspension, bolt means being provided to clamp a wheel bearing on the tubular member, said bolt means comprising an externally threaded member and clamping means, said clamping means comprising a plurality of angularly spaced jaws arranged for engagement of the internal diameter of the tubular member, each jaw having an outer edge for engagement of the internal diameter of the tubular member and an inner edge, each inner edge tapering outwardly towards the inboard end of the tubular member, a wedge member being provided with a threaded aperture for engagement of the externally threaded member, the wedge member defining a plurality of faces, each face engaging one of the inner edges of each jaw, the faces of the wedge member being parallel to the inner edges of the jaws, and resilient means being provided to bias the jaws outwardly so that their outer edges engage the internal diameter of the tubular member.
With the invention described above, the clamping means is located within the tubular member so that the wedge member is located centrally thereof by the jaws which are urged into engagement with the internal diameter of the tubular member by the resilient biasing means. The externally threaded member is engaged in the threaded bore of the wedge member so that as the externally threaded member is tightened to locate the wheel bearing on the tubular member, the wedge member is drawn towards the outboard end of the tubular member thus causing the jaws to expand against the internal diameter of the tubular member, thereby clamping the wedge member axially with respect to the tubular member. The present invention thus provides means for securing the externally threaded member to the tubular member without the need for extensive machining operations.
According to a preferred embodiment of the present invention, the jaws are located symmetrically of one another in a tubular cage. Furthermore, the outer edges of the jaws are preferably serrated in order to improve the grip on the internal diameter of the tubular member.
An embodiment of the invention is now described, by way of example only, with reference to the accompanying drawings, in which:
Figure 1 is a partial sectional elevation of a stub axle/hub assembly in accordance with the present invention; and
Figure 2 is a sectional perspective view of the stub axle illustrated in Figure 1.
As illustrated in the drawings, a stub axle 10 is formed from standard tube, machined on its external diameter to provide a flange portion 11 at its inboard end and a portion 12 of greater wall thickness abuting the flange 11. The portion 12 of stub axle 10 is a press fit within an aperture 13 in the vertical link 14 of the vehicle suspension, the flange portion 11 abutting the rear face of the link 14.
Wheel bearings 20 and hub 21 are located on the stub axle 10 by means of washer 22 which is secured by bolt 23.
The bolt 23 is secured to the stub axle 10 by means of a clamping assembly 25 which is located within the bore 26 of the stub axle 10. The clamping assembly 25 comprises four jaws 30 which are located symmetrically in a tubular cage 31, the jaws 30 extending radially through axially extending slots 32 in the cage 31. Each of the jaws 30 has an outer edge 35 which is disposed substantially parallel to the internal surface of the tubular stub axle 10. The outer edges 35 are provided with saw tooth serrations 36. Inner edge 38 of each jaw 30 is inclined outwardly relative to the axis of the tubular stub axle 10 towards the inboard end of the stub axle 10. A split spring ring 40 engages the inner edges 38 of the jaws 30, adjacent their inboard ends, to bias the jaws 30 outwardly.
A wedge member 42 is located centrally of the jaws 30.
The wedge member 42 has a central screw threaded bore 43 for engagement of the screw thread 44 of the bolt 23.
The wedge member 42 is of square section, defining four faces 45 each parallel to the inner edge 38 of one of the jaws 30.
To assemble the axle, the stub axle 10 is located through the aperture 13 in vertical link 14 and is pressed into position so that the flange portion 11 abuts the rear face of the vertical link 14. The hub 21 with wheel bearings 20 mounted thereon is then located on the protruding portion of the stub axle 10. The clamping assembly 25 with threaded portion 44 of bolt 23 partially engaged in the threaded bore 43 of the wedge member 42 and with the washer 22 located between the clamping mechanism 25 and the head of the bolt 23, is located into the bore 26 of stub axle 10. In order to facilitate introduction of the clamping mechanism 25 into the bore 26, a compression tool may be used to retract the jaws 30 into the cage 31, against the load imposed by spring ring 40, the clamping mechanism 25 may then be introduced into the bore 26.The threaded portion 44 of the bolt 23 may then be engaged with the threaded bore 43 and tightened, resilient engagement of the jaws 30 against the internal diameter of the stub axle 10 preventing rotation of the clamping mechanism 25. When the washer 22 abuts against the inner face of the wheel bearing 20, further tightening of the bolt 23 will draw the wedge member 42 towards the outboard end of the stub axle 10 causing the jaws 30 to move outwardly thus increasing the clamping load between the clamping mechanism 25 and the internal diameter of the stub axle 10. The saw tooth serrations 36 on the jaws 30 will prevent movement of the clamping mechanism 25 towards the outboard end of the stub axle 10.
Expansion of the clamping mechanism 25 in the manner described above, will ensure that the bolt 23 is firmly anchored with respect to the stub axle 10 without the need for accurate machining of the internal diameter of the stub axle 10.
Various modifications may be made without departing from the present invention. For example, while in the above embodiment the clamping mechanism has four jaws, two or more jaws may be used. Preferably there are three or more jaws and these are arranged symmetrically in order to provide accurate lateral location of the bolt. The wedge member will be of suitable configuration to provide a face corresponding to the angular position of each jaw.
