A vehicle axle assembly is provided including an axle housing having legs extending along an axis. Each housing leg has a wall defining an interior cavity with the wall having a first locating feature formed therein. The first locating feature may be an indentation in the wall of the axle housing that may be in the shape of a concave dimple or a trough running transverse to the axis. The first locating feature may also be a protrusion instead of an indentation. A suspension component is secured to the housing leg by clamps. A suspension component includes a second locating feature of a complimentary shape to the first locating feature. The locating features cooperate to axially locate the suspension component on the housing leg preventing lateral movement.
Description
- This invention relates to a vehicle axle arrangement, and more particularly, the invention relates to an arrangement for attaching a suspension component to an axle housing that prevents lateral movement between the suspension component and axle housing.
- Vehicle axles are connected to the vehicle frame by suspension assemblies, which dampen the harsh inputs from the roadway transmitted through the wheels. The suspension assembly is typically attached to the axle housing by clamps. The axle housing and suspension assembly must be sufficiently secured to one another such that they do not move relative to one another, particularly in the lateral direction, over time from the harsh inputs from the roadway.
- Hollow axle housings are frequently used. The clamp assembly is used to secure the suspension assembly to the axle housing generate a preload that may decrease during the operation of the vehicle. As the preload decreases, the axle may walk relative to the suspension assembly resulting in an undesirable alignment of the axle. Solid axle housings may be used for non-drive axle applications. For solid axles, lateral movement is not as great of a concern as for hollow axle housings because the preload does not decrease as greatly.
- In the prior art, the suspension assembly and axle housing have been secured to one another using a variety of mechanisms. For example, a hole is drilled into the axle housing and a dowel pin is inserted into the hole. A component of the suspension assembly includes a hole that receives the end of the dowel protruding from the axle housing to laterally locate the suspension component and axle housing relative to one another. In another similar arrangement, a pin is welded onto the top side of the axle housing and is received by a hole in the suspension component similar to the manner described above. The drawback with the dowel pin arrangement is that it sometimes comes loose during operation and the suspension component can move along the axle housing. The drawback with the welded pin is that the welding operation adds significant cost to the manufacture of the axle. As an alternative to the two arrangements described above, the suspension component is welded directly to the axle housing, which presents problems with servicing the suspension assembly or axle.
- Therefore, what is needed is an improved axle housing suspension seat arrangement that is less costly and more effective for the duration of vehicle operation.
- The present invention provides a vehicle axle assembly including an axle housing having legs extending along an axis. Each housing leg has a wall defining an interior cavity with the wall having a first locating feature formed therein. The first locating feature may be an indentation in the wall of the axle housing that may be in the shape of a concave dimple or a trough running transverse to the axis. The first locating feature may also be a protrusion instead of an indentation. A suspension component is secured to the housing leg by clamps. A suspension component includes a second locating feature of a complimentary shape to the first locating feature. The locating features cooperate to axially locate the suspension component on the housing leg preventing lateral movement. Furthermore, the arrangement of locating features described above may also be used for a solid axle.
- Accordingly, the above invention provides an improved axle housing suspension seat arrangement that is less costly and more effective for the duration of vehicle operation.
- Other advantages of the present invention can be understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:
-
FIG. 1 is a perspective view of a vehicle suspension system; -
FIG. 2 is an exploded perspective view of the present invention axle housing and suspension component; -
FIG. 3 is a cross-sectional view of the vehicle suspension system shown inFIG. 2 ; -
FIG. 4 is a perspective view of another configuration of a locating feature in the axle housing; and -
FIG. 5 is a flowchart of the present invention axle manufacturing process. - A
vehicle suspension system 10 is shown schematically inFIG. 1 . Thesystem 10 includes anaxle 12 havingopposing housing legs 14 extending longitudinally along an axis A. Although a hollow drive axle is shown, it will be understood from the description below that the present invention may be used with non-drive axles and solid axles. - A
suspension component 16 of a suspension assembly is secured to theaxle 12 with aclamp assembly 18. Thesuspension component 16 is shown very schematically. It should be understood that the component may be any device secured to vehicle structures other than axles. Theclamp assembly 18 generates a preload that may decrease during vehicle operation. Accordingly, a mechanism is typically used to laterally locate thesuspension component 16 relative to thehousing leg 14 to prevent movement in the direction L throughout the operation of the vehicle. - The housing leg includes a
wall 20 defining a longitudinalinterior cavity 22. - The
wall 20 may be constructed from one or more portions welded to one another, as discussed in more detail below. Thewall 20 includesside walls 24 andlateral walls 26 extending between theside walls 24, as best shown inFIG. 2 . Thewalls unbroken wall 20, which is shown by the cross-section in the Figures. Thewall 20 has generally uniform thickness. - The
axle housing leg 14 andsuspension component 16 have complimentary locatingfeatures 28 that prevent undesired lateral movement between thehousing leg 14 andsuspension component 16 during operation of the vehicle. More specifically, thewall 20 may include a first locatingfeature 30, and the suspension component may include a second locatingfeature 32 complimentary in shape to the first locatingfeature 30. For example, the first locatingfeature 30 may be a dimple or concave depression formed in theexterior surface 31, and the second locatingfeature 32 may be a complimentary-shaped protrusion to the dimple 33. - Referring to
FIG. 3 , the first locatingfeature 30 is formed by thewall 20 so that no additional structure such as a welded pin is required. The first locatingfeature 30 may be constructed during the stamping operation in which the axle is formed. For example, theaxle 12 may be formed by securing first 34 and second 36 housing portions to one another by aweld bead 38. During this stamping operation, the first locatingfeature 30 may be formed simultaneously. In this manner, no additional operations are required to provide the first locatingfeature 30. Alternatively, the first locatingfeature 30 may be formed into thehousing leg 14 subsequent to any axle housing forming operation. In the case of a solid axle, the first locatingfeature 30 may be formed by a forming or drilling operation. - Referring now to
FIG. 4 , it will be appreciated that the locatingfeatures 28 may be of any suitable shape to prevent relative movement between thesuspension component 16 and thehousing leg 14 in the lateral direction L. The first locatingfeature 30 may be in the shape of atrough 40 plastically deformed into thewall 20 in a direction transverse to the axis A. Thesuspension component 16 includes a protrusion of a complimentary shape to the trough 40 (not shown) to form the second locatingfeature 32. Furthermore, it will be appreciated that the first locatingfeature 30 may be a protrusion instead of a depression, and the second locatingfeature 32 may be a complimentary shaped depression to receive the protrusion in theaxle housing leg 14. -
FIG. 5 depicts the present inventionaxle manufacturing process 42. Theaxle housing 12 is formed in the desired shape, as indicated atblock 44. The axle housing may be formed by securing one or more housing portions to one another by a weld bead, or by any other suitable manufacturing process. The first complimentary locatingfeature 30 is formed into the axle housing, as indicated atblock 46. The first locating feature may be formed simultaneously with the axle forming process of 44 or subsequent thereto. Thesuspension component 16 having asecond locating feature 32 complimentary to thefirst locating feature 30 is assembled onto theaxle 12, as indicated atblock 48. Aclamp assembly 18 may be used to secure thesuspension component 16 to theaxle 12. - The invention has been described in an illustrative manner, and it is to be understood that the terminology that has been used is intended to be in the nature of
