This disclosure claims the benefit of Provisional Patent Application No. 60/724,194, filed on Oct. 6, 2005.
FIELDThe disclosure generally relates to devices for mounting, inflating, and balancing a tire relative a wheel and more particularly to automated systems for removing an entrapment between a tire bead and a bead seat of a wheel prior to balancing an inflated tire mounted to a wheel.
BACKGROUNDTire/wheel assembly facilities may incorporate one or more automated tire/wheel assembly lines for preparing vehicle tires and vehicle wheels. This process typically involves, amongst other operations: (a) the mounting of a tire onto a wheel, (b) the inflating of the tire to the desired pressure, and (c) the balancing of the tire/wheel assembly.
Although automated tire/wheel assembling systems are known in the art, their use includes several drawbacks. One of these drawbacks includes their inability to flush entrapments, such as, for example, air bubble(s), lubricant, or the like, which may be microscopic in size, residing between a tire bead and a wheel bead seat when a tire is mounted to the wheel. Once the entrapment is present, it is factored into the balancing of the tire/wheel assembly. Subsequently, if the entrapment is bled out (e.g. during vehicle operation) the tire/wheel assembly may become imbalanced.
Accordingly, a need therefore exists for a device that removes entrapments, such as for example, air bubble(s), lubricant, or the like prior to balancing a tire/wheel assembly. As such, the present invention provides tire/wheel assemblies that may be balanced without entrapments, thereby increasing the potential that the tire/wheel assembly will not become imbalanced during normal operation of the vehicle.
The present disclosure will now be described, by way of example, with reference to the accompanying drawings, in which:
A tire/wheel assembly is shown generally at 10 and a tire/wheel bead entrapment remover is shown generally at 100 and 200 in
Referring to
The tire/wheel bead entrapment remover 100, 200 also includes a second working assembly 102b positioned on a support surface 52 of the cart 50. As illustrated, an inboard circumferential perimeter surface 18 of the tire 12 is positioned on top of a circumferential perimeter 103b of the second working assembly 102b. The second working assembly 102b is attached to a second vacuum device 117b driven by the controller 113 and connected to the second working assembly 102b by a hose 121.
According to an embodiment, the working assemblies 102a, 102b are designed to circumferentially and, optionally, sealingly-engage the outboard and inboard surfaces 16, 18 of the tire 12 to remove any entrapments, such as, for example, microscopic air bubbles, B (

According to the embodiment shown in
Once the plunger portion 109 moves the first working assembly 102a to an engaged position as described above, the outer peripheral portions 107 of platens 104a, 104b circumferentially engage the outboard and inboard surfaces 16, 18 of time 12 while leaving a space S, between a facing surfaces 112a, 112b and an outermost circumferential periphery 28, 30 of the wheel 14. By leaving sufficient space S, axial movement of the wheel 14 relative the axially-fixed positioning of the platens 104a, 104b, as described below, will not result in contact between the platens 104a, 104b and the wheel 14.
According to an embodiment, the hub engagement mechanisms 108a, 108b are oscillated, respectively, according to the direction of arrows, F, F′, in accordance with forces provided from one or more of the oscillating motors 106a, 106b, respectively. The forces, according to the direction of arrows, F, F′, may be substantially parallel to an axis of rotation, A-A, of the tire/wheel assembly 10. Accordingly, the working output shafts 110a, 110b and/or hub engagement mechanisms 108a, 108b work on and axially-oscillate the positioning of the wheel 14 relative the axially-fixed positioning of the platens 104a, 104b that engage the outboard and inboard surfaces 16, 18 of the tire 12.
Referring to
Referring now to
The hub engagement mechanisms 108a, 108b and working output shafts 110a, 110b are designed to clamp and hold the wheel 14 in an axially-fixed position as the platens 104a, 104b are designed to engage and axially-move the positioning of the tire 12 relative the axially-fixed positioning of the wheel 14. Accordingly, once the plunger portion 109 moves the first working assembly 102a to an engaged position as described above, the outer peripheral portions 107 of platens 104a, 104b circumferentially engage the outboard and inboard surfaces 16, 18 of the tire 12 while leaving a space S, between a facing surface 112a, 112b of each respective platen 104a, 104b and an outermost circumferential periphery 26, 28 of the wheel 14. By leaving space S, axial movement of the platens 104a, 104b and tire 12 relative the axially-fixed positioning of the wheel 14, as described below, will not result in contact between the platens 104a, 104b and the wheel 14.
According to an embodiment, the platens 104a, 104b are axially-moved (e.g. axially-oscillated) according to the direction of arrows, F, F′, in accordance with forces provided from the platen moving devices 206a, 206B, respectively. The forces according to the direction of the arrows, F, F′, may be substantially parallel to an axis of rotation, A-A, of the tire/wheel assembly 10. Accordingly, axial movement of the platens 104a, 104b work on and axially-move/axially-oscillate the positioning of the tire 12 relative the axially-fixed positioning of the wheel 14.
Referring to
Accordingly, because of the relative movement caused between tire 12 and wheel 14, contact between the tire bead 22 and the wheel bead seat 24 is interrupted. This interruption primarily is characterized by portions of the outboard/inboard tire bead 22 being temporarily pulled away from the seating surface of outboard/inboard wheel bead seat 24. By axially moving the tire 12 or wheel 14 while holding the other in an axially-fixed relationship in this way, any entrapments, such as, for example, air bubbles, B, that may be entrapped between the tire bead 22 and the wheel bead seat 24 is/are released.
According to an embodiment, the first and/or second vacuum devices 117a, 117b may be activated when the tire 12 or wheel 14 is axially-moved as described above. As seen in
Referring now to
The tire/wheel bead entrapment remover 300 also includes at least one kneading wheel 308a, 308b. As illustrated, the kneading wheel 308a engages the outboard surface 16 of the tire 12, and the kneading wheel 308b engages the inboard surface 18 of the tire 12. The kneading wheels 308a, 308b are manipulated to engage the outboard and inboard surfaces 16, 18, respectively, of the tire 12 generally proximate the area 20 that defines the region of the tire bead 22 and wheel bead seat 24.
As illustrated in
According to an embodiment, the radial axis, R-R, is substantially misaligned with the radial line, X, and does not pass through the axis of rotation, A-A. By radially misaligning radial axis, R-R, with the radial line, X, the intersection of the radial axis, R-R, and the radial line, X, creates an offset angle, θ.
Accordingly, as seen in
In an alternative embodiment as shown in
The wobble-wheel 408a, 408b is not snuggly fit to the radial axis, R-R, but rather, the wobble-wheel 408a, 408b is loosely-fitted about the radial axis, R-R. By loosely-fitting the wobble-wheel 408a, 408b relative the radial axis, R-R, the wobble-wheel 408b, 408b is allowed to “wander” or “wobble” and deviate angularly +/−between bounds defined by deviation angle, +Δ, −Δ (
Accordingly, the wobbling effect, W, will introduce, in addition to kneading action, a dynamic vibration, pulling, and other disruptive forces, which is shown generally at KVP. The kneading, vibration, and pulling force, KVP, would otherwise not be present if wobble wheel 408a, 408b was tightly affixed to the radial axis, R-R, as shown and described in
By providing the disruptive forces, FVP, associated with the wobbling effect, W, the outboard and inboard surface 16, 18 of the tire 12, during rotation of the tire/wheel assembly 10, temporarily disrupts the interface between the tire bead 22 and the wheel bead seat 24, thereby releasing any entrapments, such as, for example, air bubbles, B, therebetween. Although not illustrated, vacuum sources 117a, 117b may be included as shown in
According to an embodiment, the tire/wheel bead entrapment removers 300, 400 may include optional rollers 310, 312, 314 that can be used to steady the overall movement of tire/wheel assembly 10 during rotation. Additionally, according to an embodiment, the rollers 310, 312, 314 can be attached to a drive motor and can be used to rotate tire/wheel assembly 10. Although the rollers 310, 312, 314 are shown engaging the outboard surface 16 of the tire 12, it will be appreciated that rollers 310, 312, 314 may be applied alone or in combination proximate the inboard surface 18 of the tire 12.
The present invention has been described with reference to certain exemplary embodiments thereof. However, it will be readily apparent to those skilled in the art that it is possible to embody the invention in specific forms other than those of the exemplary embodiments described above. This may be done without departing from the spirit of the invention. The exemplary embodiments are merely illustrative and should not be considered restrictive in any way. The scope of the invention is defined by the appended claims and their equivalents, rather than by the preceding description.
