Description
~Z4504~
This application relates to a tool which facilitates removal of a spindle from the wheel assembly of a motor vehicle.
It is particularly applicable to the front wheel spindles in certain four-wheel drive motor vehicles.
BACRGROUND OF T~E INV~NTIO~
It is necessary from time to time for repair or replacement to disassemble the front wheel assembly in a motor vehicle. In some cases, particularly in certain four-wheel drive vehicles, the front wheel spindles are removed by removing the securing bolts and pulling the spindle free of the assembly.
Frequently corrosion and foreign matter adds to the frictional resistance to removal of the spindle to the extent that the spindle is virtually welded to the steering gear knuckle in the assembly. The problem is aggravated in a number of vehicle models where the spindle is actually recessed into the knuckle.
To date in order to free the spindle, it has been necessary to apply a hammer laterally to attempt to jar the spindle free or to apply heat to the assembly. In either case there is a substantial risk of damage to other parts of the wheel assembly, particularly the seals and the bearings. Accordingly, there has been a need for an improved means of spindle removal which will avoid the risk of damage to the spindle itself and to other parts of the wheel assembly.
To that end a tool has now been developed which will i24s0~
facilitate the ready withdrawal of the spindle without the imposition of heat or of lateral direct impact with a hammer.
The inventive tool permits a slide hammer to be used to exert longitudinal force on the spindle to jar it free of the wheel assembly.
PRIOR ART
The inventor is unaware of any relevent prior art, prior techniques being in the nature of the hammering or heating described above.
Of peripheral interest is United States Patent 4,185,372, granted January 29, 1980, to Dupree for a wheel hub support removal means. That patent relates to an adaptor tool for enabling removal of a tapered sleeve joining a farm tractor hub support to the drive axle. The tool in that case is directed to a different type of wheel assembly from the present case and requires a completely different type of adaptor tool.
BRI~F SUMMARY OF T~E INVEMTION
The inventor has developed an adaptor tool which will enable a slide hammer to be attached to the spindle to be removed, so that the force required to jar the spindle free can be exerted outwardly of the wheel assembly and axially of the spindle.
12~3~
Thus, the invention provides a spindle puller tool comprising a body portion having first and second ends, at the first end of the body portion a longitudinally aligned threaded bore adapted to threadedly engage a spindle, and at the second end of the body portion a longitudinally aligned threaded bore adapted to threadedly engage a slide hammer.
BRIEF D~SCRIPTION OF THE DRAWINGS
In drawings which illustrate embodiments of the lnventlon:
FIGURE 1 is a perspective view illustrating the tool of the present invention along with a spindle and part of a slide hammer;
FIGURE 2 is an end view of one end of the tool of the invention; and FIGURE 3 is an end view of the second end of the tool according to the invention.
While the invention will be described in conjunction with an illustrated embodiment, it will be understood that it is not intended to limit the invention to such embodiment. On the contrary, it is intended to cover all alternatives, modficiations and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims.

DFTAIL~D D~SCRIPTION OF T~E: PREF~RRED EMBODIMENTS
The spindle puller tool 10 comprises a body portion 12 having a first end 14 and a second end 16. The spindle 18 which is to be removed from the wheel assembly using the puller tool 10 is provided with a threaded end 20. It is of importance to the working of the invention that a variety of such spindles include as a standard feature the threaded end 20. It is also of importance to the working of the invention that a variety of such spindles 18 are adapted to be removed from a wheel assembly by pulling the spindle axially outwardly from the assembly.
The first end 14 of the body portion 12 includes a threaded bore 22 of which the diameter and thread size is such as to allow the tool 10 to be threadedly engaged with the threaded end 20 of spindle 18.
It is to be noted that the force to be applied through the tool 10 to the spindle 18 is an axially directed force.
Accordingly, it is not necessary that the tool 10 be particularly tightly attached to the spindle 18. It is only necessary that the threaded engagement be such that the axial force to be exerted by the tool. 10 on the spindle 18 will not cause stripping or distortion of the threads in either the tool 10 or the spindle 18.
The second end 16 of body portion 12 of tool 10 is similarly provided with a threaded bore 24. The threaded bore 24 is of such a diameter in thread size as to be adapted to receive ~45~4~
in threaded engagement the threaded end 26 of a slide hammer 28.
As with the connection between the first end 14 of tool lO and threaded end 20 of spindle 18, no turning moment will be imposed in use as between the threaded end 26 of slide hammer 28 and the threaded bore 24 in the second end 16 of tool 10. Accordingly, the connection between the threaded end 26 of hammer 28 and the threaded bore 24 in end 16 of tool lO need not be particularly tight but need only involve sufficient ~hreads that the axial force exerted between hammer 28 and tool 10 will not strip or otherwise damage the threads of either component.
In use with the tool lO screwed onto the spindle 1.8 and the har~er 28 screwed into the bore 24, the impact of the slide hammer axially of the hammer 28, tool 10 and spindle 18 will jar the spindle free without damaging other components of the wheel assembly, The ends 14 and 16 of body portion 12 of tool 10 are illustrated with a hexagonal exterior configuration. This configuration facilitates the use of a wrench where necessary to make the connection as between the tool lO and the spindle 18 and hammer 28. Particularly with respect to the spindle 18, the threaded end 20 may be damaged somewhat in use, so that the tool lO may not always be readily engagable with the threaded end 20 by simple hand twisting of tool lO. In these instances the use of a wrench may be necessary to engage the end 14 of tool 10 with threaded end 20. Similarly, to steady the tool 10 to facilitate entry of the hammer 28, a wrench may be applied to the end 16 of '~24~j~4 tool lO.
While a substantial number of ~orth American four-wheel drive vehicles include standard size front-wheel spindles having a one and one-half inch diameter thread with sixteen threads per 5 inch, clearly the end 14 of tool 10 may differ in regard to thread diameter and size for various specific applications. As well, the opposite end 16 may vary to accommodate specific hammer sizes. A kit may therefore be assembled containing a series of common thread combinations to accommodate different sizes at the ends of tool lO.
Thus it is apparent that there has been provided in accordance with the invention a spindle puller tool that fully satisfies the objects, aims and advantages set forth above.
While the invention has been described in conjunction with a specific embodiment thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description.
Accordingly, it is intended to embrace all such alternatives, modifications and variations as fall within the spirit and broad scope of the invention.
This application relates to a tool which facilitates removal of a spindle from the wheel assembly of a motor vehicle.
It is particularly applicable to the front wheel spindles in certain four-wheel drive motor vehicles.
