Abstract

A method of attaching a seal to a cylindrical housing is disclosed. The seal is placed over the housing and located in a seal groove. Heat is then applied which melts the boot, causing the boot to conform and adhere to the housing. A metal boot clamp can then be placed around the seal if additional retention is desired.

M13THOD OF ATTAC~ING A 8~AL q~O ~_CYLINDRICAL ~OU8ING

BACRGROUND OF T~ N'I!ION
This invention relates generally to a method of attaching a seal to a cylindrical housing. More particularly, this invention relates to attaching a seal to a constant velocity joint housing and shaft.
Front wheel drive vehicles utilize a pair of halfshaft assemblies to transmit the power from the transaxle to the front wheels. Each halfshaft assembly comprises a pair of constant velocity joints connected by an interconnecting shaft. One constant velocity joint is connected to the front wheel. The other constant velocity joint is connected to the transaxle.
The constant velocity joint located at the wheel is a fixed center constant velocity joint. This joint is capable of high angles (45 - 50). The high angular capability of this joint allows the front wheels to accommodate steering angles.
The constant velocity joint located at the transaxle is a plunging constant velocity joint. This joint has a movable center of rotation and is capable of angles of 20 - 25.
The movable center of rotation along with the angular capacity of the joint allows for build tolerances of the vehicle as well as suspension movements and engine vibrations.
Constant velocity joints require a continuous supply of lubricant within which to operate. Normally this lubricant is contained within a chamber created by a seal or boot. The seal is usually made from a flexible material, either rubber or 2~ 8 59~3 plastic. The boot is attached to the outer diameter of the constant velocity joint at one end. The other end is attached to the interconnecting shaft. This arrangement creates a generally conical shaped chamber which is filled during the assembly of the halfshaft with a predetermined amount of grease.
This grease is normally sufficient to lubricate the constant velocity joint for the life of the vehicle.
The constant velocity joint seals are a critical component of the halfshaft assembly due to the requirement of continuous supply of lubricant. If for some reason, the seal would fail, this failure would be virtually undetectable to the operator of the vehicle. Once the seal allows the lubricant to leak out of the assembly, failure of the constant velocity joint will follow shortly.
The flexibility of the seal allows for angular movement of the shaft relative to the constant velocity joint housing.
During angulation of the joint, the boot is subjected to compression on one side while the opposite side is elongated.
As the joint operates at angle, the boot goes through a cyclic compression and elongation movement. The frequency of this cyclic action is dependent upon the speed of rotation of the joint.
Early constant velocity joint seals were made of a rubber or neoprene material. This material provides excellent flexibility and is easily attached to the constant velocity joint housing and shaft by using a metal band. While these rubber seals perform acceptably, the softness of the rubber material ~8~ 6~1 makes them highly susceptible to pinch cuts.
Cutting of the rubber boot can occur during handling of the halfshaft, during vehicle assembly or by contact between the boot and other vehicle components during the vehicle assembly. Once properly assembled, the rubber boots can be damaged by road hazards, pry bars used by mechanics, towing hooks or other objects which pinch the boot between the object and one of the other halfshaft components.
Plastic boots, normally Dupont ~ytrel, were developed to reduce or eliminate the susceptibility of pinch cutting. The plastic material being tougher than the rubber material is able to withstand a reasonable amount of mishandling and other abuse which would pinch cut a rubber boot.
Unfortunately, along with the increased toughness comes the difficulty in attaching the plastic boots to the outer races and shafts of the halfshaft assemblies. The plastic material requires a metal band with a larger cross section to hold and seal the boot on the halfshaft components during operation. In addition to an increased cross-section, the material of the metal band is changed from inexpensive galvanized steel to relatively expensive stainless steel. The increase in cross-section along with the change to a more expensive material has significantly increased the cost of the clamping system of the boot.
Accordingly it is desirous to have a method of attaching plastic constant velocity joint boots to a halfshaft assembly which is low cost and reliable.

8UMMARY OF T~ INVENTION
The present invention provides the art with a method of attaching a plastic boot to a halfshaft assembly. The boot is placed into position and then heated to shrink and shape the boot onto the halfshaft assembly.

DETAIL DE8~RIPTION OF THE INVENTION
The detail description will describe the attaching of a plastic seal to a fixed center ball jOillt end of a halfshaft assembly. It is assumed that a person skilled in the art, can take the attaching methods herein described and apply them to the other types of universal joints.
Referring now to the drawings and particularly to Figures 1 and 2, a fixed center constant velocity joint end of a halfshaft is shown and is designated by the reference numeral 10.

2~8~9~
The attachment method begins by positioning a plastic seal 20 over an interconnecting shaft 22. The plastic seal is manufactured from Dupont Hytrel by blow molding techniques well known in the art. The small end of the seal 24 is positioned in a groove 26 located on the outside surface 28 of the interconnecting shaft 22. This positions one end of the seal 20 relative to the end of the interconnecting shaft 22.
The interconnecting shaft 22 and seal 20 are then assembled to the constant velocity joint assembly 30. Normally the interconnecting shaft 22 and the inner race 32 of the constant velocity joint are connected by spline means 34 as shown in Figure 1.
The large end 36 of seal 20 is then positioned over the outer race 38 of the constant velocity joint assembly 30. The seal 20 has a ribbed projection 40 which fits into a groove 42 machined into the outer surface 44 of the outer race 38. The ribbed projection 40 is mated with the groove 42 to properly position the seal 20 relative to the constant velocity joint assembly 30.
The chamber 50 formed by the seal 20, the outer race 36 and the interconnecting shaft 22 is then filled with the proper type and amount of lubricant.
The ends 24 and 38 of the seal 20 are then heated to a temperature slightly above their melting temperatures. This heating of the seal can be accomplished by introducing an exterior heat source by methods well known i~ the art around the ends 24 and 38 of the seal 20. Another method of introducing the 2~859~

necessary heat would be to induction heat the outer race 36 and the interconnecting shaft 22, also by methods well known in the art. The induction heating of the outer race 36 and the interconnecting shaft 22 can easily be controlled to a localized heating area thereby only affecting the areas of the seal 20 designed for attachment.
once the melting temperature of the seal 20 has been achieved, the heat source is removed and the assembly is allowed to cool. The cooling of the assembly 10 allows the seal 20 to conform to and adhere to the outer race 36 and the interconnecting shaft 22.
Normally the attachment of seal 20, once attached to the joint assembly 30 and interconnecting shaft 22 as described by the above method, is a reliable and complete assembly. In order to provide a greater confidence in the attachment of the seal 20, metal bands 52 and 54 can be assembled over the seal 20 as shown in Figure 3. The metal bands 52 and 54 as well as the technique for tightening them are similar to the low cost galvanized steel bands used to retain a rubber seal and are well known in the art.
While the above detailed description describes the preferred embodiment of the present invention, it should be understood that the present invention is susceptible to modification, variation and alteration without deviating from the scope and fair meaning of the subjoined claims.
