Abstract

A joint for use in the suspension of a road vehicle comprises a bolt (44) which passes through both a hole (see 50) in a bracket (40) and the end of a radius rod (30,32). An inner liner/spacer sleeve (46) surrounds the bolt and a resilient sleeve (52) is interposed between the liner (46) and radius rod (30,32). The bolt (44) is splined (48) at one end such that on tightening, it cuts into the wall (50) of the hole in the bracket (40) and into the lining sleeve (46) such that they are both held immovably relative one another to eliminate or reduce wear and tear therebetween. <IMAGE>

Description

SPECIFICATION Road vehicle suspensions This invention relates to road vehicle suspensions and in particular but not exclusively to multi-axle suspensions and in particular to the joints between radius rods or their equivalent and brackets and/or axle/spring seats (such joints will hereafter be referred to as "joints of the type described").
Such joints comprise a bolt which passes through a hole in a plate or a pair of plates attached to one member to be joined and through a hole in a second member, a metal lining/spacer sleeve surrounding the bolt and a resiiient, usually rubber, sleeve being interposed between the liner and the walls of the hole in the second member.
However, as wear and tear occurs small but significant relative movement takes place between the liner and the plate or plates of the first member. The wear in particular on the ends of the lining sleeve results in the joint having to be "re-bushed".
It is an object of the invention to overcome or mitigate this problem.
In accordance with the invention a joint of the type described for the suspension of a road vehicle has a bolt having at least one end portion splined so that when the bolt is tightened the spline cuts into the wall of the hole in one plate of the first member and into the lining sleeve so that the plate and lining sleeve are immovably held relative one another.
As the lining sleeve and plate(s) are immovably held relative one another, wear and tear between these parts is eliminated or very much reduced.
Preferably the joint in accordance with the invention is used to join the two pla+es of a bracket with a radius rod of a suspension, the bracket/radius rod connecting an axle to the road vehicle.
The invention wili now be described, by way of example, with reference to the accompanying drawing, in which: Figure 1 is a side view of a tandem axle vehicle suspension incorporating a number of joints in accordance with the invention, and Figure 2 is an enlarged detail of one of the joints shown in Figure 1.
The tandem suspension 10 shown in Figure 1 which is provided at each side of a road vehicle comprises parabolic leaf springs 12, 14 for the relatively forward and rearward axles 1 6, 18 of a pair which in tandem carry load, the axles being connected to the leaf springs by conventional U-bolts 20.
Both ends of both leaf springs are engaged by slipper pads 22, the pads 22a at one end of the springs being supported by a bracket 24 (for the front axle) and 28 (for the rear axle) and the pads 22b at the other end of the springs being carried by a rocker plate 26 (for both front and rear axles).
The rocker plate 26 is pivotally connected to a side rail of the road vehicle (not shown) via a hanger bracket 27 to which it is pivotted about a pivot 29.
As the slipper pads 22 only rest on the ends of the springs, the axles are not located longitudinally and hence radius rods 30, 32 are provided. The rods 30 and 32 are pivotally attached at one end (about axes 34) between the two plates or arms 40 of the brackets 36 which in turn is connected to the U-bolt members 20 and axles 1 6 and 1 8 respectively. The rods are pivotally attached at the other end (about axes 38) between the two arms 40 of the brackets 24 and 27 respectiveiy.
The arrangement is such that when the vehicle is laden and running with the suspension in the general position illustrated in Figure 1, the suspension acts to transfer some of the load applied from one axle to the other. Further details for the suspension shown in Figure 1 and examples of other such general arrangements of suspension can be ascertained from our G.B.
Patent Nos. 1503142 and 2030088.
As described above, the radius rods 30, 32 are pivotted at each end between two arms 40 of a bracket. In Figure 2 the joint between the radius rod and bracket arms is shown in greater detail.
The joint comprises a nut 42 and bolt 44, an inner iiner/spacer sleeve 46 around the bolt 44 and between the arms 40 of the bracket, and an outer flexible rubber sleeve 52 about the inner sleeve 46.
The inner sleeve 46 separates the arms of the brackets by a fixed distance when the nut is tightened. The end of the radius rod 30 or 32 is mounted on the outer sleeve 52 and can move relative the inner sleeve 46 due to the torsion stretchability of the sleeve 52. The end of the rod is at the same time positioned by the sleeve 52 between the arms of the bracket without contact thereto.
To prevent relative movement of the inner sleeve 46 to the arms 40 of the bracket and accordingly prevent wear and tear in particular to the end of the sleeve, one end of the bolt 44 is splined at 48 so that when the bracket/radius rod joint is assembled, the spline 48 cuts into both a wall 50 of a hole in one arm of the bracket and the inner surface 54 of the sleeve 46 to hold the sleeve 46 and bracket immovably relative one another.
Clearly the inner radius of the hole 50 and inner surface 54 must be substantialiy the same as the inner radius of the splined part of the bolt, in order for the spline 48 to cut into the wall 50 and inner surface 54.
1. A joint of the type described for the suspension of a road vehicle wherein the bolt has at least one end portion splined so that when the bolt is tightened the spline cuts into the wall of the hole in one plate of the first member and into the lining sleeve so that the plate and lining sleeve are immovably held relative one another.
2. Joint as claimed in Claim 1 wherein the first member is a bracket having two plates.
