Definitions
- a wheelend assembly typically includes a main body or hub defining a cavity that receives an axle, spindle, or the like.
- the main body houses an inboard bearing assembly, a spacer (optionally), and an outboard bearing assembly.
- the spacer generally acts to maintain the distance between the inboard bearing assembly and the outboard bearing assembly and may allow limited movement of both such that the bearing and the associated race/cup can properly seat.
- the wheelend assembly also includes a spindle nut, oil seal, and retainer located on the assembly.
- the inboard bearing assembly is on the inboard side and is bounded by an oil seal.
- the oil seal secures the inboard side of the wheelend assembly to inhibit the inboard bearing, the spacer, etc. from moving further.
- An end cap or retainer is typically placed over the outboard bearing and coupled to the main body to inhibit the wheelend assembly from unloading to the outboard side of the main body.
- the unitized wheelend assembly may be disassembled and packed with a lubricant.
- this defeats the purpose of providing a unitized wheelend assembly as the assembly of the wheelend is exacting, cumbersome, and difficult.
- the wheelend bearings are installed on the spindle dry.
- the cavity of the wheelend assembly is provided with lubricant in the normal course. The hope being that during operation the lubricant from the cavity will migrate to the inner and outer bearings.
- this is a less than desirable solution as the level of lubrication to the bearings is unknown and lubrication in wheelends is generally viscous and of limited flowability.
- a grease system for providing lubrication to an inner bearing and an outer bearing of a unitized wheelend assembly.
- the grease system has an inner grease tool and an outer grease tool.
- the inner grease tool includes a plug having a sidewall shaped to engage the unitized wheelend assembly.
- the plug includes a fluid conduit formed in the plug where the fluid conduit includes an inlet configured to place the lubrication source in fluid communication with the fluid conduit and an outlet, formed in the sidewall of the plug, in fluid communication with the fluid conduit such that lubrication can be delivered from a lubrication source to the inner bearing.
- the outer grease tool comprises a cap configured to couple with a retainer of the unitized wheelend assembly.
- the cap includes a fluid conduit.
- the outer grease tool comprises an inlet and an outlet, where the outlet is proximal the outer bearing, to place the lubrication source in fluid communication with the outer bearing of the unitized wheelend assembly.
- the cap comprises a cover portion coupled to a base portion.
- a grease system for providing lubrication to an inner bearing and an outer bearing of a unitized wheelend assembly includes a body shaped to fit a spindle bore of a unitized wheelend assembly where the body has a proximal side configured to be proximal the inner bearing of the unitized wheelend assembly and a distal side opposite the proximal side and configured to be proximal the outer bearing of the unitized wheelend assembly.
- An inner rotor and an outer rotor are rotationally coupled to the body.
- the inner rotor is operationally coupled to an extendable and retractable inner disc.
- the outer rotor is operationally coupled to an extendable and retractable outer disc. Rotation of the inner/outer rotor moves the extendable and retractable inner/outer disc between the extended and retracted position.
- a plurality of fluid conduits extending through the body are configured to deliver lubricant to a chamber adjacent to the inner bearing and the outer bearing when the inner rotor and the outer rotor are in the extended position.
- the body is coupled to a lever that causes rotation of the inner/outer rotor.

- the internal grease system 500 has a proximal side 602 (which may be referred to as the inner grease tool part 502) and a distal side 604 (which may be referred to as the outer grease tool part 504).
- the stand 506 has a bore 606 (figure 5) through which a shaft 607 of the internal grease system 500 extends.
- the stand 506, as can be appreciated, may function as the plugs described above.
- the shaft 607 extends from the proximal side 602 to the distal side 604, which shaft 607 includes the fluid channels and conduits similar to the fluid channels and conduits explained above.
- the bore 606 receives a nut 614 that receives the shaft 607 of the internal grease system 500.
- the stand 506 has a slot 608 (figure 5), which receives a lever 610, explained further below.
- the lever 610 coupled to an adapter 612 (or sleeve 612) that is rotationally coupled to the shaft 607.

- the lubricant is forced from the hub side of the wheelend assembly into the bearings.
- the wheelend assembly is slid onto the cylindrical body of the grease tool system and arranged horizontally (similar to how it is deployed on a vehicle). With the wheelend deployed on the internal grease system, the lever is rotated to rotate the rotors and cause the dams to move from the retracted to the extended position.
- the lubrication source is placed in fluid communication with both the inner and outer fluid channels and conduits. Once the amount of lubricant is delivered, the lever or counter rotate to retract the dams to the retracted position.
- the wheelend is removed from the tool and installed on the vehicle spindle in a conventional manner with packed bearings.
- the grease tool 650 shown in figure 10, is a slightly different configuration to place the outer bearing in fluid communication with the lubrication source.
- the flow configuration provides the fluid conduit from the retainer side of the unitized wheelend assembly instead of the oil seal end.
- FIG 11-13 shows alternative internal grease systems 700, 800, and 900.
- the internal grease system 700, 800, 900 includes an inner bearing tool portion 702, 802, 902 and an outer bearing tool portion 704, 804, 904, both of which are designed to engage the inner and outer bearings 701/703, 801/803, 901/903 of the wheelend assembly 705, 805, 905.
- the internal grease systems 700, 800, 900 include an inner bearing support 706, 806, 906 which is an annular surface on the inner bearing tool portion 702, 802, 902 of the cylindrical body of the internal grease system 700, 800, 900 and an outer bearing support 708, 808, 908, which is a protrusion and flanged surface on outer bearing tool portions 704, 804, 904.
- the internal grease systems 700, 800, 900 include elastic members that are elastically deformed and folded about the cylindrical body of the internal grease systems. The elastic members return to a deployed position to form a seal with the inner and outer bearing.
- a stated range of 1 to 10 should be considered to include and provide support for claims that recite any and all subranges or individual values that are between and/or inclusive of the minimum value of 1 and the maximum value of 10; that is, all subranges beginning with a minimum value of 1 or more and ending with a maximum value of 10 or less (e.g., 5.5 to 10, 2.34 to 3.56, and so forth) or any values from 1 to 10 (e.g., 3, 5.8, 9.9994, and so forth).
