- a differential assembly houses a gear assembly that is traditionally configured to change a direction of a power input from a drive shaft to two half shafts.
- the drive shaft receives power from an engine and through a transmission, while the half shafts deliver power to the wheels from the differential assembly.
- the differential assembly is generally indicated by reference numeral 10 .
- a drive shaft 12 enters a differential assembly housing 14 , also referred to as a carrier housing 14 , at a front portion 16 of the housing 14 .
- a gear assembly 17 or differential gear set, transfers power to a right half shaft 18 a and a left half shaft 18 b , which hereinafter are collectively referred to as half shafts 18 .
- the housing 14 also has a plurality of mounting brackets 20 that are configured to secure the differential assembly 10 within the applicable subassemblies (not shown) of the vehicle (not shown).
- solid beam axle housings can be divided into two groups, an integral carrier, or a removable carrier.
- the integral carrier housing attaches directly to the rear suspension.
- a service cover in the center of the housing, fits over the rear of the differential and axle assembly. When service is required, the cover must be removed and the components of the differential unit are then removed.
- Integral carriers are also commonly referred to as unitized or salisbury-type differentials, named after C. W. Salisbury one of the founders of Salisbury Axle Company.
- a removable carrier assembly is configured so that the gearing assembly can be removed from the front of the differential housing as a unit, when the front portion of the differential housing unit is removed.
- a rear axle refers an axle mounted in the rear of a vehicle and to the rear tires.
- the front of the rear axle refers to the area which the driveshaft connects thereto and live denotes that the axle carries power, such as in a rear wheel drive vehicle.
- the typical housing of a removable carrier assembly has a cast-iron center section with axle shaft tubes pressed and welded into either side.
- the removable carrier assembly is sometimes called a “banjo” because of the bulge in the center of the housing.
- the bulge contains the final drive gears and differential gears.
- the two designs of axle housing look similar except that the opening for the differential unit on a banjo axle is at the front and the rear of the housing is solid, while access to the salisbury axle is through a rear service cover.
- the housing 14 further includes a differential assembly cover 22 , which attaches to a rear portion 24 of the housing 14 with a plurality of fasteners 26 .
- the rear portion 24 defines a window 24 a that provides access to the interior cavity of the housing 14 .
- the differential assembly 10 is salisbury differential, as the cover 22 is a separate component that is releaseably connected to the rear of the housing 14 .
- Disposed between the housing 14 and the differential assembly cover 22 is a gasket 28 .
- the gasket 28 seals the differential assembly cover 22 to the housing.
- the gasket 28 must be placed over the housing 14 in a proper orientation to ensure proper installation when the cover 22 is secured to the housing 14 . It will be further appreciated that misalignment of the gasket 28 may lead to improper sealing of the gasket 28 , which may manifest itself in leaks from the housing 14 . Misalignment may also cause the gasket 28 to be pinched or crimped by the fasteners 26 when the cover 22 is secured to the housing 14 . The pinched or crimped gasket 28 may also improperly seal when the cover 22 is secured to the housing 14 .
- the fasteners 26 When the cover 22 is secured to the housing 14 , the fasteners 26 must be secured so as to apply a clamping force about the perimeter of the cover 22 .
- the clamping force causes the gasket 28 to compress and thus form a seal between the cover 22 and the housing 14 .
- the gasket 28 not only serves to retain the internal lubrication of the differential assembly 10 , but also protects the differential assembly from the regimes of driving environment, such as water, salt, and dirt.
- the axle of a vehicle is located along the underbelly of the vehicle and by the very nature of its location is exposed to not just water, salt, and dirt as mentioned above but may also be exposed to high-pressure water from conventional car washes.
- the gasket 28 must not only seal the lubrication in the differential assembly, it must also keep many things out of differential assembly, so water, dirt, salt and the like does not pollute the lubrication.
- an incorrect amount of clamping force applied to the cover 22 may lead to improper sealing of the gasket 28 .
- Over-tightening the fasteners 26 may generate too much clamping force and over compress the gasket 28 , such that the gasket 28 may bulge or kink, which is sometimes referred to as coining.
- Coining and over-compression in general may lead to leaks especially when the gasket expands and contracts due to heating and cooling the assembly 10 .
- An axle assembly that includes a differential gearset in a carrier housing.
- a housing cover is coupled to the carrier housing and is operable for sealingly closing a window on the carrier housing through which there is access to the differential gearset.
- the housing cover includes a cover member and a seal ring.
- the cover member includes a mating face and a plurality of raised connection points that are disposed between the carrier housing and the mating face.
- the seal ring is coupled to the mating face and encircles each of the raised connection points.
- the seal ring further includes at least first and second ring members that are disposed between each of the raised connection points. The seal ring sealingly engages the carrier housing and the mating face.

- the seal ring 106 may include at least a first sealing member 112 and a second sealing member 114 that may be approximately concentric with the first sealing member 112 .
- the seal ring 106 can also include a web member (not shown) that connects the first sealing member 112 to the second member 114 . It will be appreciated that either the first sealing member 112 and/or the second sealing member 114 may be individually applied or connected to the cover mating face 110 directly or as an assembly incorporating the web member (not shown) therebetween.
- the seal ring 106 is attached to the cover mating face 110 with a suitable adhesive. It will be appreciated that when the cover 100 is secured to the housing 14 ( FIG. 1 ) there is no need to align a separate gasket as the sealing ring has already been affixed to the cover mating face 110 in the proper orientation. It will be further appreciated that the sealing member can contain one sealing member or a plurality of sealing members.
- the cover 100 also includes a plurality of raised connection points 116 .

- the distance in the elevation between each of the raised connection points 116 and an end 106 a of the seal ring 106 opposite face 110 is referred to as the compression distance.
- the cover 100 can be stamped as one piece.
- the stamping process creates, among other things, the bowl portion 102 , the raised connection points 116 , and the cover mating face 110 along with the general geometry of the bowl.
- the seal ring 106 can be affixed to the cover 100 during the stamping process, so that the cover 100 and the seal ring 106 can be produced as a single unit. This can not only eliminate the need to match the cover 100 to the gasket 28 ( FIG. 2 ), this can also reduce production time, part cost and inventory control issues.
- FIG. 4 a portion of the cross-section of the cover 100 is shown with the seal ring 106 encircling the raised connection point 116 .
- a segment of the bowl portion 102 connects with the cover mating face 110 .

- a plurality of fasteners 122 secure the cover 100 to a housing mounting face 130 of a housing 132 .
- the raised connection point 116 makes direct contact with the housing mounting face 130 and by virtue of the geometry of the cover 100 , the seal ring 106 is compressed to a desired distance.
- the desired distance to compress the seal ring 106 between the cover mating face 110 and the housing mounting face 130 may be the compression distance.
- the housing 132 can be a salisbury differential housing, wherein the cover 100 is a modified housing cover configured to secure to a salisbury differential housing.
- the cover 100 may also be modified to seal to an axle assembly configured with independent suspension or to various transaxles.
- the cover 100 can also be used in other areas of the vehicle beyond its use on front or rear axles.
- the cover 100 is placed over the housing 132 and secured to the housing with the plurality of fasteners 122 . It will be appreciated that when the apertures 118 of the connection points 116 are aligned with the housing mounting face 130 , the seal ring 106 is necessarily aligned properly to the housing 132 . The plurality of fasteners 122 are then used to secure the cover 100 to the housing 132 . When the fasteners 122 are secured, the configuration of the cover 100 is such that the seal ring 106 is properly compressed between the cover mating face 110 and the housing mounting face 130 . As such, the seal ring 106 can be compressed by an amount equal to the compression distance between the cover mating face 110 and the housing mounting face 130 , while the connection points 116 make direct contact with the housing mounting face 130 .
- a proper seal between the housing cover 100 and the differential housing 132 is required to not only contain lubrication within the differential housing 132 but also keep out the many pollutants to which the exterior of the differential housing is exposed.
- pollutants for example, include water, salt spray, dirt, oil, and the like.
- axle assemblies are commonly exposed to high-pressure wash systems or driven through water both of which can add to the need to have a robust seal between the housing cover 100 and differential housing 132 .
- FIG. 6 depicts a portion of the cover 100 using a shoulder bolt, which is generally indicated by reference numeral 134 .
- the shoulder bolt 134 has a head 136 from which a shank 138 extends.
- the shank 138 has a threaded-portion 140 and a non-threaded-portion 142 , which is located between the threaded portion 140 and the head 136 .
- the length of the shank 138 includes a length of the threaded-portion 140 and a length of the non-threaded-portion 142 , which are indicated by reference numerals 144 and 146 , respectively, a shown in FIG. 7 . It will be appreciated that the threaded portion 140 has a smaller diameter than the non-threaded portion 142 , such that the end of the non-threaded portion 142 , adjacent to the threaded portion 140 , generally forms a shoulder 142 a.
- the shoulder bolt 134 can be inserted into a threaded aperture 148 or a conventional nut. It will be appreciated that the shoulder bolt 134 can only be inserted a distance 144 into the threaded aperture 148 . As shown in FIG. 6 , the shoulder bolt 134 is inserted through the differential assembly cover 100 and the housing 132 . The shoulder bolt 134 is then secured into the threaded aperture 148 . It will be appreciated that the shoulder bolt 134 compresses the cover 100 against the housing 132 enough to properly clamps the seal ring 106 therebetween. As such, the shoulder bolt 134 limits the compression of the seal ring 106 as the shoulder bolt 134 can only be inserted the distance 144 into the threaded aperture 148 .
- a compression limiter (not shown) may be introduced between the cover 100 and the housing 132 to establish a proper compression distance for the seal ring 106 .
- a compression limiter may take the form of a sleeve (not shown) over a conventional fastener, which may be used to limit the insertion of the fastener. While introducing compression limiters may be a less expensive option than using shoulder bolts, compression limiters add to the overall parts count of the assembly and can increase the overall cost of the process.

Description
- This application is a continuation of U.S. patent application Ser. No. 10/755,962 filed on Jan. 12, 2004. The disclosure of the above application is incorporated herein by reference.
- The present invention relates to a differential cover for a vehicle drivetrain assembly and further relates to a double seal ring that is pre-attached to the differential cover that also includes integral compression limiters.
- A differential assembly houses a gear assembly that is traditionally configured to change a direction of a power input from a drive shaft to two half shafts. The drive shaft receives power from an engine and through a transmission, while the half shafts deliver power to the wheels from the differential assembly. With reference to
FIG. 1 , the differential assembly is generally indicated byreference numeral 10. Adrive shaft 12 enters adifferential assembly housing 14, also referred to as acarrier housing 14, at afront portion 16 of thehousing 14. Agear assembly 17, or differential gear set, transfers power to aright half shaft 18 a and aleft half shaft 18 b, which hereinafter are collectively referred to as half shafts 18. Thehousing 14 also has a plurality ofmounting brackets 20 that are configured to secure thedifferential assembly 10 within the applicable subassemblies (not shown) of the vehicle (not shown). - Based on their construction, solid beam axle housings can be divided into two groups, an integral carrier, or a removable carrier. The integral carrier housing attaches directly to the rear suspension. A service cover, in the center of the housing, fits over the rear of the differential and axle assembly. When service is required, the cover must be removed and the components of the differential unit are then removed. Integral carriers are also commonly referred to as unitized or salisbury-type differentials, named after C. W. Salisbury one of the founders of Salisbury Axle Company.
- A removable carrier assembly is configured so that the gearing assembly can be removed from the front of the differential housing as a unit, when the front portion of the differential housing unit is removed. With reference to rear live axles, a rear axle refers an axle mounted in the rear of a vehicle and to the rear tires. The front of the rear axle refers to the area which the driveshaft connects thereto and live denotes that the axle carries power, such as in a rear wheel drive vehicle. The typical housing of a removable carrier assembly has a cast-iron center section with axle shaft tubes pressed and welded into either side. The removable carrier assembly is sometimes called a “banjo” because of the bulge in the center of the housing. The bulge contains the final drive gears and differential gears. In appearance, the two designs of axle housing look similar except that the opening for the differential unit on a banjo axle is at the front and the rear of the housing is solid, while access to the salisbury axle is through a rear service cover.
- It will be appreciated that variations of the salisbury and the banjo axles exist, such as independent front and rear axles. With an independent front or rear axle, the differential housing is mounted to the vehicle's chassis. As such, the differential housing does not move with the suspension. The half axles, however are connected to the wheels of vehicle which are suspended. To that end, constant velocity joints are used to connect the half axles to the differential assembly and the wheel hubs so that the half axles are able to move with the suspended wheels. The differential housing remains unsuspended and secured to the applicable subassemblies of the vehicle.
- With reference to
FIG. 1 andFIG. 2 , thehousing 14 further includes adifferential assembly cover 22, which attaches to arear portion 24 of thehousing 14 with a plurality offasteners 26. Therear portion 24 defines awindow 24 a that provides access to the interior cavity of thehousing 14. It will be appreciated that thedifferential assembly 10 is salisbury differential, as thecover 22 is a separate component that is releaseably connected to the rear of thehousing 14. Disposed between thehousing 14 and thedifferential assembly cover 22 is agasket 28. Thegasket 28 seals the differential assembly cover 22 to the housing. By sealing thecover 22 to thehousing 14, the gear assembly contained therein is protected from the regime in which it is installed. Thecover 22 also forms a sealed volume of space in which the gear assembly is constantly lubricated. - It will be appreciated that the
gasket 28 must be placed over thehousing 14 in a proper orientation to ensure proper installation when thecover 22 is secured to thehousing 14. It will be further appreciated that misalignment of thegasket 28 may lead to improper sealing of thegasket 28, which may manifest itself in leaks from thehousing 14. Misalignment may also cause thegasket 28 to be pinched or crimped by thefasteners 26 when thecover 22 is secured to thehousing 14. The pinched or crimpedgasket 28 may also improperly seal when thecover 22 is secured to thehousing 14. - When the
cover 22 is secured to thehousing 14, thefasteners 26 must be secured so as to apply a clamping force about the perimeter of thecover 22. The clamping force causes thegasket 28 to compress and thus form a seal between thecover 22 and thehousing 14. Thegasket 28 not only serves to retain the internal lubrication of thedifferential assembly 10, but also protects the differential assembly from the regimes of driving environment, such as water, salt, and dirt. It will be appreciated that the axle of a vehicle is located along the underbelly of the vehicle and by the very nature of its location is exposed to not just water, salt, and dirt as mentioned above but may also be exposed to high-pressure water from conventional car washes. It will be appreciated that thegasket 28 must not only seal the lubrication in the differential assembly, it must also keep many things out of differential assembly, so water, dirt, salt and the like does not pollute the lubrication. - To that end, an incorrect amount of clamping force applied to the
cover 22 may lead to improper sealing of thegasket 28. Over-tightening thefasteners 26, for example, may generate too much clamping force and over compress thegasket 28, such that thegasket 28 may bulge or kink, which is sometimes referred to as coining. Coining and over-compression in general may lead to leaks especially when the gasket expands and contracts due to heating and cooling theassembly 10. - It is desirable, therefore, to secure the differential assembly cover to the housing without a separate compression limiting device. It is further desirable to have the compression limiting device pre-configured into the differential assembly cover. It is also desirable to have a seal pre-attached to the differential assembly cover that is cost-effective and robust. It is additionally desirable to avoid the steps of aligning the gasket while securing the differential assembly cover to the housing.
- An axle assembly that includes a differential gearset in a carrier housing. A housing cover is coupled to the carrier housing and is operable for sealingly closing a window on the carrier housing through which there is access to the differential gearset. The housing cover includes a cover member and a seal ring. The cover member includes a mating face and a plurality of raised connection points that are disposed between the carrier housing and the mating face. The seal ring is coupled to the mating face and encircles each of the raised connection points. The seal ring further includes at least first and second ring members that are disposed between each of the raised connection points. The seal ring sealingly engages the carrier housing and the mating face.

Thecover 100 has abowl portion 102 that can be configured to surround a portion of the gear assembly 17 (FIG. 1 ) contained in thedifferential assembly housing 14, as shown inFIG. 1 . When thecover 100 is secured to the housing 14 (FIG. 1 ), the gear assembly 17 (FIG. 1 ) inside is not only protected from the elements outside of the housing 14 (FIG. 1 ) but is also sealed inside with lubrication. A modifiedconventional drain plug 104 can be integrated into thecover 100. - A
seal ring 106 encircles aperimeter 108 of thecover 100. Theperimeter 108 of thecover 100 includes acover mating face 110. Theseal ring 106 is connected to thecover mating face 110, which encircles thebowl portion 102, such that when thecover 100 is attached to the housing 14 (FIG. 1 ), at least thebowl portion 102 is sealed from the outside. - The
seal ring 106 may include at least afirst sealing member 112 and asecond sealing member 114 that may be approximately concentric with thefirst sealing member 112. Theseal ring 106 can also include a web member (not shown) that connects thefirst sealing member 112 to thesecond member 114. It will be appreciated that either thefirst sealing member 112 and/or thesecond sealing member 114 may be individually applied or connected to thecover mating face 110 directly or as an assembly incorporating the web member (not shown) therebetween. - In the various embodiments of the present invention, the
seal ring 106 is attached to thecover mating face 110 with a suitable adhesive. It will be appreciated that when thecover 100 is secured to the housing 14 (FIG. 1 ) there is no need to align a separate gasket as the sealing ring has already been affixed to thecover mating face 110 in the proper orientation. It will be further appreciated that the sealing member can contain one sealing member or a plurality of sealing members. - The
cover 100 also includes a plurality of raised connection points 116. The plurality of raised connection points 116 are integral to thecover mating face 110 and define a plurality ofapertures 118 within the connection points 116 spaced along theperimeter 108 of thecover 100. In the various embodiments, there are ten (10) connection points 116 that are approximately equally spaced apart from one another. It will be appreciated, that while ten (10) connection points 116 are depicted inFIG. 3 , more or less connection points 116 can be used as size, geometry, and sealing requirements change in a given application. - The
seal ring 106 encircles eachconnection point 116 so that a continuous seal is formed around thebowl portion 102 of thecover 100. It will be appreciated that the raisedconnection point 116 is at a different elevation than a portion of thecover mating face 110 adjacent to the raisedconnection point 116, as shown inFIGS. 4 and 5 . To that end, theseal ring 106 encircles eachconnection point 116 but theseal ring 106 is otherwise mounted to thecover mating face 110 at a lower elevation when compared to the elevation of theconnection point 116. In the various embodiments, the distance in the elevation between each of the raised connection points 116 and anend 106 a of theseal ring 106opposite face 110 is referred to as the compression distance. - In the various embodiments, the
cover 100 can be stamped as one piece. The stamping process creates, among other things, thebowl portion 102, the raised connection points 116, and thecover mating face 110 along with the general geometry of the bowl. Moreover, theseal ring 106 can be affixed to thecover 100 during the stamping process, so that thecover 100 and theseal ring 106 can be produced as a single unit. This can not only eliminate the need to match thecover 100 to the gasket 28 (FIG. 2 ), this can also reduce production time, part cost and inventory control issues. - With reference to
FIG. 4 , a portion of the cross-section of thecover 100 is shown with theseal ring 106 encircling the raisedconnection point 116. A segment of thebowl portion 102 connects with thecover mating face 110. Each of theapertures 118 is formed within each of the raised connection points 116. It will be appreciated that theseal ring 106 is shown in an uncompressed state inFIG. 4 , and in a compressed state inFIG. 5 . - With reference to
FIG. 5 , afastener 122 is shown having ahead 124 and a threadedshank 126 that is at least partially inserted within a threadedaperture 128. A plurality offasteners 122 secure thecover 100 to ahousing mounting face 130 of ahousing 132. It will be appreciated that the raisedconnection point 116 makes direct contact with thehousing mounting face 130 and by virtue of the geometry of thecover 100, theseal ring 106 is compressed to a desired distance. In the various embodiments, the desired distance to compress theseal ring 106 between thecover mating face 110 and thehousing mounting face 130 may be the compression distance. - In the various embodiments, the
housing 132 can be a salisbury differential housing, wherein thecover 100 is a modified housing cover configured to secure to a salisbury differential housing. Thecover 100 may also be modified to seal to an axle assembly configured with independent suspension or to various transaxles. Moreover, thecover 100 can also be used in other areas of the vehicle beyond its use on front or rear axles. - The
cover 100 is placed over thehousing 132 and secured to the housing with the plurality offasteners 122. It will be appreciated that when theapertures 118 of the connection points 116 are aligned with thehousing mounting face 130, theseal ring 106 is necessarily aligned properly to thehousing 132. The plurality offasteners 122 are then used to secure thecover 100 to thehousing 132. When thefasteners 122 are secured, the configuration of thecover 100 is such that theseal ring 106 is properly compressed between thecover mating face 110 and thehousing mounting face 130. As such, theseal ring 106 can be compressed by an amount equal to the compression distance between thecover mating face 110 and thehousing mounting face 130, while the connection points 116 make direct contact with thehousing mounting face 130. - It will be appreciated that a proper seal between the
housing cover 100 and thedifferential housing 132 is required to not only contain lubrication within thedifferential housing 132 but also keep out the many pollutants to which the exterior of the differential housing is exposed. Some of the pollutants, for example, include water, salt spray, dirt, oil, and the like. Moreover, axle assemblies are commonly exposed to high-pressure wash systems or driven through water both of which can add to the need to have a robust seal between thehousing cover 100 anddifferential housing 132. - Other devices can be employed to address compression of the
seal ring 106 a proper distance or put another way to limit compression. Any such device must not only be robust, easy to use, and compliant with other materials, it must also be cost effective in a mass production scale.FIG. 6 depicts a portion of thecover 100 using a shoulder bolt, which is generally indicated byreference numeral 134. Theshoulder bolt 134 has ahead 136 from which ashank 138 extends. Theshank 138 has a threaded-portion 140 and a non-threaded-portion 142, which is located between the threadedportion 140 and thehead 136. The length of theshank 138 includes a length of the threaded-portion 140 and a length of the non-threaded-portion 142, which are indicated byreference numerals FIG. 7 . It will be appreciated that the threadedportion 140 has a smaller diameter than thenon-threaded portion 142, such that the end of thenon-threaded portion 142, adjacent to the threadedportion 140, generally forms ashoulder 142 a. - The
shoulder bolt 134 can be inserted into a threadedaperture 148 or a conventional nut. It will be appreciated that theshoulder bolt 134 can only be inserted adistance 144 into the threadedaperture 148. As shown inFIG. 6 , theshoulder bolt 134 is inserted through thedifferential assembly cover 100 and thehousing 132. Theshoulder bolt 134 is then secured into the threadedaperture 148. It will be appreciated that theshoulder bolt 134 compresses thecover 100 against thehousing 132 enough to properly clamps theseal ring 106 therebetween. As such, theshoulder bolt 134 limits the compression of theseal ring 106 as theshoulder bolt 134 can only be inserted thedistance 144 into the threadedaperture 148. - In lieu of the
shoulder bolt 134, a compression limiter (not shown) may be introduced between thecover 100 and thehousing 132 to establish a proper compression distance for theseal ring 106. In various embodiments, a compression limiter may take the form of a sleeve (not shown) over a conventional fastener, which may be used to limit the insertion of the fastener. While introducing compression limiters may be a less expensive option than using shoulder bolts, compression limiters add to the overall parts count of the assembly and can increase the overall cost of the process. - The description of the invention is merely exemplary in nature and, thus, variations that do not depart from the gist of the invention are intended to be within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
