The present invention generally relates to devices for changing vehicular components such as wheels and engines.
The reference in this specification to any prior publication (or information derived from it), or to any matter which is known, is not, and should not be taken as an acknowledgment or admission or any form of suggestion that that prior publication (or information derived from it) or known matter forms part of the common general knowledge in the field of endeavour to which this specification relates.
A number of devices are known which can be used for changing vehicular components. A common device used for such purposes is a jack that is placed underneath a vehicle and used to elevate the vehicle off the ground such that a wheel can be replaced. A jack is generally placed substantially near the exterior perimeter of the vehicle such that the wheel may be removed from the axle.
However, in situations where the vehicle includes at least two tyres on a common axle, such as is the situation with large machinery and vehicles, and an inner wheel needs to be changed, the internal wheel may not easily be accessed, because a confined space exists between the wheels on adjacent axles.
Thus, there exists a need for a device that is capable of aiding the changing of vehicular components in confined spaces that address or at least ameliorate problems inherent in the prior art.

The present invention should become apparent from the following description, which is given by the way of example only, of a preferred but non-limiting embodiment thereof, described in connection with the accompanying figures.
The following embodiments, given by way of example only, are described in order to provide a more precise understanding of the subject matter of a preferred embodiment or embodiments.
In the figures, incorporated to illustrate features of an example embodiment, like reference numerals are used to identify like parts throughout the figures.
An example of a device for changing a vehicular component on a vehicle will now be described with reference to FIGS. 1(a) and 1(b).
The device 10 includes a frame 20 for releasably receiving a vehicular component 30, wherein the frame 20 is configured to facilitate the frame being positioned in a component changing position with respect to the first vehicle. The device 10 also includes a first actuator 50 for moving the frame 20 between a first position and a second position to thereby mount the vehicular component on the first vehicle or receive the vehicular component from the first vehicle. In one form, the device includes a mounting member 40 for releasably mounting the device to a second vehicle 200.
As shown in FIGS. 2(a) and 2(b), the device 10 is able to be positioned in a confined space between adjacent axles 130 of the first vehicle. The second vehicle 200 mounted to the mounting member 40 positions the device 10 in a component changing position within the confined space, as represented by arrows 99 in FIGS. 2(a) and 2(b). When the device 10 is placed in the component changing position, the frame 20 is substantially aligned with at least one of the adjacent axles 130.
Once the device 10 is positioned in the component changing position, the frame 20 is moved from a first position to a second position such that the vehicular component 30 can be mounted on the first vehicle or received from the first vehicle. When the frame is positioned in the first position, the frame 20 is positioned distally from one of the axels 130 of the first vehicle, as shown in
When a vehicular component 30 is to be mounted to the first vehicle, the frame 20 supports the vehicular component 30 whilst the device is being placed in the component changing position. Once the device 10 is placed in the component changing position, the first actuator 50 can be actuated to move the frame 20 between the first position and the second position.
Alternatively, if a vehicular component 30 is to be received from the first vehicle, the device 10 is positioned in the component changing position such that the frame 20 can be moved from the first position to the second position so that the frame 20 receives the vehicular component 30 from the first vehicle in the second position. Then the first actuator 50 can be actuated again so as to cause the frame 20 to move from the second position back to the first position, allowing the vehicular component 30 to be disengaged from with the first vehicle. The device 10 can then be removed from the component changing position between the adjacent axles by reversing the second vehicle 200 allowing easy removal of the vehicular component from between the adjacent axels 130 of the first vehicle.
The device 10 allows a vehicular component 30 to be mounted or removed to or from the vehicle in a confined space, which in this example is the gap between adjacent wheels 120, 125 and/or axels 130 of the first vehicle. Generally, by positioning the device 10 in the component changing position between adjacent axles 130, an inner wheel 125 on an axle 130 or an engine 160 for a particular wheel (as will be described in more detail later) can be easily changed, removed or mounted without having to remove the external wheel 120 of the first vehicle.
Referring back to
The slidable members can includes guide members 28 to guide the movement of the moveable members 27 along the legs 26 of the support structure 25. In one form, the guide members 28 may take the form of guide rollers which facilitate the slidable movement of the moveable member 27 along the legs 26.
The support structure 25 is similarly an elongate shape such that the support structure 25, including the frame 20, can be positioned between adjacent axles 130. The support structure 25 generally includes at least one support wheel 14, as shown more clearly in
The frame 20 generally includes one or more support members 70, which can be provided in the form of rollers 70 which support and retain a received vehicular component 30. As shown in
The rollers 71, 72 permit the vehicular component to rotate within the frame 20 by rotating on the external surface of the respective rollers 71, 72. This can be advantageous when a component needs to be rotated within the frame, for example aligning lugs and holes of a vehicular component with a portion of the first vehicle.
The frame 20 can generally include a profile similar to the shape of the received vehicular component 30. Thus, as shown in
The mounting member 40 is capable of being releasably mounted to a second vehicle 200, so that the second vehicle 200 can position the device 10 in the component changing position. As shown in
Referring to FIGS. 2(a), 2(b) and 2(c), the support structure is indirectly connected to the mounting member 40 via a moveable plate 45. As can be seen in FIGS. 3(a), 3(b) and 3(c), the first actuator 50 is located between the mounting member 40 and the moveable plate 45, wherein the moveable plate is connected to the support structure 25 and frame 20. On activation of the first actuator 50, the moveable plate 45 moves relative to the mounting member 40, moving the frame 20 and support structure 25 from the first position to the second position, or reversely from the second position to the first position.
The support structure 25 is moveably mounted to the moveable plate 45 such that the support structure 25, including the frame 20, may be repositioned relative to the moveable plate 45. This relative movement is accomplished using a number of actuators located on the moveable plate 45 and/or the support structure 25.
The device can include one or more second actuators 110 positioned between the moveable plate 45 and the support structure 25 to rotate the frame 20 about an axis 210, as shown in FIGS. 4, 5(b) and 6. A plurality of second actuators 110 may be placed at opposite ends of the moveable plate 45 such as to facilitate the rotational movement of the support structure 25 about the axis 210.
The device can also include one or more third actuators 90 located between each moveable member 27 and the support structure 25 so as to adjust the elevation of the frame 20 relative to the supporting surface.
The device can also include one or more fourth actuators 150 for rotating the frame 20 about a frame axis 220 as shown in
As shown in
The device can also include one or more fifth actuators 100 located between the support structure 25 and the moveable plate 45. Actuation of the fifth actuator 100 can cause the support structure 25 to extend away from the moveable plate 45, or reversely can cause the support structure 25 to move toward the moveable plate. The fifth actuator 100 can be used to accurately align the device with an axel 130 when the second vehicle is unable to perform such accurate alignment.
As shown in FIGS. 7(a), 7(b) and 7(c), the device can include a separable cradle 170 which engages with a portion of the frame 20 so that a vehicular component such as an engine 160 may be releasably received by the frame 20 and cradle 170 in order to manoeuvre, receive and/or mount an engine 160 onto or from the first vehicle.
In particular regard to large machinery, each wheel or pair of wheels may be driven by an independent or dedicated engine 160. In such situations, a respective engine 160 for a particular wheel or pair of wheels may also need to be changed. Thus, the device 10 can be positioned between adjacent axles 130 of a vehicle to change an engine 160 of the first vehicle.
As shown in FIGS. 7(a) and 7(b), the cradle 170 may releasably engage with the rollers 70 of the frame 20 such as to support the engine 160. The cradle 170 engages with the rollers 70 using cradle engagements 180. The engine 160 is supported in the cradle 170 and may be retained to the cradle 170 using fasteners 190. Once the engine 160 has been fastened to the cradle 170, the cradle 170 can be rotated using the various actuators previously discussed by rotating or manoeuvring the frame 20.
It will be appreciated that a number of different actuators may be used. Generally, for example, the actuators may be in the form of a piston and cylinder arrangement which move using hydraulics. It will be appreciated that other forms of actuators could also be used. A controller may also be provided with the device 10 to control the actuation of each actuator.
In one optional embodiment, the device 10 may include a transportation mechanism such as an engine to facilitate the positioning of device in the component changing position. In this optional embodiment, the device 10 does not necessarily require a mounting member to allow positioning of the device using the second vehicle 200 due to the transportation mechanism performing the functionality.
Additionally or alternatively, retainment of the vehicular component 30 can be further provided using a locking member 60 as shown in a
In another optional embodiment, the frame 20 can include a seperatable side bar member 86, as shown in
In one form, the separateable side bar member 86 may include a plurality of portions 87, wherein the portions 87 engage together with the frame 20. When a vehicular component 30 is to be received by the frame 20, the side bar member 86 is separated from the frame 20 such that a gap exists in the frame 20 to allow the frame 20 to receive the vehicular component 30. Once the vehicular component 30 has been received, the side bar member 86 re-engages with the frame 20.
In an alternative embodiment, the first actuator 50 may be located remotely on the second vehicle 200, wherein the second vehicle 200 manoeuvres the frame 20 between the first position and second position.
In an optional embodiment, the device 10 can include a roller actuator which when actuated causes rotational movement of the rollers 70 subsequently causing rotational movement of the vehicular component 30 retained within the frame 20.
