Abstract:
The present invention relates generally to tire servicing operations and, more specifically, to an improved tire bead seating device. The bead seating device may include an inlet configured to receive pressurized air. The inlet may couple to two or more outlets extending outwardly from a shell of the device. Further, a leg may extend downwardly from each outlet and include a nozzle for directing a pressurized gas into a cavity of a tire. In particular, pressurized air may be delivered via the nozzles to force the tire bead onto the rim flange. Advantageously, the bead seating device may emit a high volume of air through each nozzle to accommodate for wheel assemblies of different diameters.
Abstract:
A pneumatic tire seater for seating a tubeless tire on a rim has an advanced rapid air release (RAR) valve mounted on a tank suitable for containing pressurized air. A nozzle is mounted on one end of the RAR valve, and the other end of the valve is in unconstrained pneumatic communication with the interior of the air tank. A piston is within a cylinder of the RAR valve. A control chamber behind the piston contains a compression spring. Control gas passageways provide constrained pneumatic communication between the control chamber and the air tank, passing control gas into the control chamber. In response to actuating a control mechanism, the air in the control chamber is vented out into the atmosphere causing the RAR valve to rapidly open, producing a blast of air of sufficient magnitude to seat a tire on a rim.
Abstract:
An apparatus for processing a tire and a wheel for forming a tire wheel assembly is disclosed. The apparatus includes a tire support member including a first tire support member, a second tire support member and a third tire support member. Each of the first, second and third tire support members include an upper surface and a lower surface. The apparatus includes a plurality of tire engaging devices including a first tire tread engaging post and a second tire tread engaging post. A method for processing a tire and a wheel for forming a tire wheel assembly is also disclosed.
Abstract:
A tire changing machine for changing difficult to mount tires is provided. The machine utilizes various implements configured about the machine's chassis in such a way that they do not interfere with each other's operation. In this way, the machine enables an operator to effectively change various tires.
Abstract:
An apparatus for mounting a tire on a wheel rim includes a mounting head with a tire bead deflector and a tire press-in roller, and a drive that moves the mounting head toward, and rotates the bead deflector and the press-in roller around, the wheel rim. To avoid a damage-causing contact between the bead deflector and the wheel rim, an arrangement for monitoring a minimum spacing distance between the wheel rim and the mounting head is arranged preferably on the bead deflector. If an improper working position closer than the minimum spacing distance is detected, the arrangement produces a signal that influences, e.g. stops, the motion of the mounting head. The arrangement preferably includes a contact member of a comparatively soft low-friction material at a working end of the bead deflector. If the contact member contacts the wheel rim, this actuates a piezoelectric element to generate the required electrical signal.
Abstract:
A method and machine for mounting tires, bead by bead, in which, after hag partially set a first bead in place in the groove of a wheel rim, that mounting of the first bead of the tire is completed by means of a rotation of the wheel and tire assembly against a mounting roller.
Abstract:
In order to rationalize and make profitable the use of machines for positing the beads of tires for finishing mounted, deliverable assemblies, the machine according to the invention comprises two plates (10), one upper and one lower, each provided with at least two cylindrical rings (4), of different diameters and axially movable independently, and also means (3, 5, 7, 11, 12, 13) which, according to the dimension of the tire of the mounted assembly E to be treated, permit the selection of the appropriate rings (4', 4"), and the adjustment of the axial distance necessary between rings, and sufficient to obtain the desired compression of the sidewalls of the tire, after application of said rings to the sidewalls of the tire of the assembly E.
Abstract:
A method and apparatus for bead setting and inflating tubeless tires on a vehicle wheel is provided. The apparatus for seating a loosely mounted tire ont he rim of the wheel comprises a compressed air tank, a support for the tank including rim engaging saddles slidably mounted on arms which ae releasably connected to the support body. Air from the tank passes out through a fast acting valve to an exhaust manifold to flexible lines and to nozzles mounted on the saddles to ensure the air is directed at the most efficient angle to the inside of the tire to expand it and force a seating of the beads. A main compressed air tank is used in conjunction with the bead seating air tank to supply air thereto and to simultaneously and subsequently supply air to the tire through a conventional tire stem to inflate the tire to the desired level.
Abstract:
An apparatus is provided for mounting on a wheel rim a deflated run-flat type tire which has been loosely preassembled on the wheel. The apparatus includes a wheel support for accommodating the preassembled tire and wheel and retaining same in a horizontal plane. A locking member coacts with the wheel support and locks the preassembled tire and wheel in the horizontal plane. An upright post is fixed a predetermined radial distance from the wheel support and is radially spaced from the periphery of the accommodated tire and wheel. A clamp device is mounted for vertical and transverse adjustment on the upright post and is adapted to clamp a segment of the beaded inner edge of the tire sidewall against a portion of a flange formed on the rim of the accommodated wheel. An installer unit is mounted at a selected elevated position relative to the accommodated tire and wheel and is adapted to be manually rotated intermittently about the axis of the accommodated wheel. The unit includes a radially extending arm having a roller piece pivotally connected ot a distal end of the arm. The roller piece is manually adjustable between operative and inoperative modes. When in the inoperative mode the roller piece rests upon a portion of the exposed surface of one sidewall of the preassembled tire, and, when in the operative mode, the roller piece pivots downwardly and inwardly toward the wheel axis causing the engaged sidewall portion to be distorted and the beaded inner edge thereof to fold over and engage the underside of a portion of the wheel rim flange.
