BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a joint between an at least hollow ended, generally cylindrical first component and a second component.
BACKGROUND OF THE INVENTION
In order to permit rotational transmission between a shaft-like first component and a second component, it is known to provide the components with interengaging splines or to key the components together. Alternatively, the shaft-like component may be provided with a flattened circumferential portion which cooperates with a flat surface on the second component.
It is also known to press fit a hollow shaft-like first component onto a tapered pin on a second component. Thus, as the first component is pressed onto the second component, the diameter of the first component is forced to increase, resulting in a decrease of the wall thickness of the first component.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an improved joint between an at least hollow ended, generally cylindrical first component and a second component, which joint is suitable for transmitting rotational and bending forces.
In accordance with the present invention, these and other objects have now been accomplished by the invention of a joint between an at least hollow ended, generally cylindrical first component and a second component, the first component comprising a first end portion terminating in a first free end region, the second end portion terminating in a second free end region, and a mid portion extending between the first and second end portion, the mid portion presenting a first predetermined external diameter and the first end portion presenting an external diameter which increases gradually from the first predetermined external diameter to a second predetermined external diameter at the first free end region, the first free end region presenting a free end from which at least one planar surface axially extends, the second component comprising a generally ring-shaped socket presenting at least one substantially planar circumferentially and axially extending surface, and a tapered pin extend from within the ring-shaped socket, wherein the first end portion of the first component is adapted to be pushed onto the tapered pin on the second component to a joined position such that in the joined position the first free end region of the first component extends into the generally ring-shaped socket of the second component and the at least one planar surface extending axially from the free end of the first free end region of the first component abuts the at least one substantially planar circumferentially and axially extending surface of the second component.
BRIEF DESCRIPTION OF THE DRAWINGS
This invention will be described in the following by way of example only and with reference to the attached drawings, in which:
FIG. 1 is a schematic perspective view of a suspension assembly for a vehicle, the assembly employing a pair of joints according to the present invention;
FIG. 2 is a schematic perspective view of two components of the suspension assembly of FIG. 1 which are to be joined by a joint according to the present invention; and
FIG. 3 is a partial sectional view through the two components of FIG. 2 in a joint condition.
DETAILED DESCRIPTION
In FIG. 1, reference numeral 10 generally denotes a suspension assembly for a vehicle, the assembly incorporating a pair of joints generally denoted by 12 according to the present invention. The joints 12 unite an at least hollow ended, generally cylindrical first component 14 and a second component 16. In the illustrated example, the first component 14 is a generally omega-shaped, hollow composite spring, while the second component 16 is a suspension arm.
With particular reference to FIGS. 2 and 3, the first component 14 comprises a first end portion 18 terminating in a first free end region 20, a second end portion 11 (FIG. 1) terminating in a second free end region, and a mid portion 24 extending between the first and second end portions. The mid portion 24 of the
