The disclosure relates to removal devices and more particularly pertains to a new removal device for separating a wheel from an axle hub. The present invention discloses a removal device comprising a plurality of tethers extending from a base. Fasteners engaged to the tethers are configured to engage apertures in a wheel. A hydraulic cylinder then can be used to separate the wheel from an axle hub to which the wheel is attached.
The prior art relates to removal devices. The prior art discloses various devices used with jacks to lift a wheel assembly or a vehicle, and one manually operated removal device which does not work with a hydraulic cylinder. What is lacking in the prior art is a removal device which can be used with a hydraulic cylinder to separate the wheel from an axle hub to which the wheel is attached.
An embodiment of the disclosure meets the needs presented above by generally comprising a base, a plurality of tethers, and a plurality of fasteners. A recess extends axially into the base from a first end of the base. The recess is shaped complementarily to a terminus of a piston of a hydraulic cylinder so that the recess is configured for insertion of the terminus of the piston. The tethers are engaged to and extend from the base. Each fastener is engaged to a respective tether distal from the base and is configured to selectively engage a wheel that is engaged to an axle hub. The hydraulic cylinder is positioned longitudinally between the base and the axle hub. The base is configured to translate a force imparted by extension of the piston through the tethers to the wheel to remove the wheel from the axle hub.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
A recess 24 extends axially into the base 12 from the first end 20 of the base 12. The recess 24 is shaped complementarily to a terminus 26 of a piston 28 of a hydraulic cylinder 30 so that the recess 24 is configured for insertion of the terminus 26 of the piston 28. The recess 24 may be shaped complementarily to a ram 32 of a bottle jack 34.
The tethers 14 are engaged to and extend from the base 12. The plurality of tethers 14 is engaged to the first end 20 of the base 12, as shown in
Each fastener 16 is engaged to a respective tether 14 distal from the base 12. The fastener 16 is configured to selectively engage a wheel 40 that is engaged to an axle hub 42, as shown in
In use, the hooks 44 are engaged to the wheel 40 by inserting them through the apertures 46. The bottle jack 34 then is positioned between the base 12 and the axle hub 42 with the ram 32 extending into the recess 24, as shown in
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
