A pneumatic tire filling station includes a support and seal arrangement on which one side wall of the tire is supported and sealed, and a tire filling bell that presses and seals against the opposite side wall of the tire and then supplies pressurized air into the tire. The filling bell includes outer and inner rings that are concentrically slidable relative to each other. One of the rings is selected for the filling operation depending on the size of the tire. The support and seal arrangement includes plural plate members that are joined and sealed together to form a continuous support and seal surface, or moved laterally apart to allow a transport apparatus to carry and support the mounted tire from underneath. The tire filling station is adaptable to different models and sizes of mounted tires even in a mixed process flow, in an automated manner.

The apparatus which protects from an explosive air blast when inflating a wheel comprises: a frame having a front side, a back side, a top side and an end portion for entry of the wheel into the cage; a transparent shield positioned on an interior front side of the frame to allow for convenient inspection of the wheel after the wheel is inflated, and to prevent the explosive air blast from passing through the front side of the cage to the technician; and, a central opening through the shield to allow the technician to access the valve on the wheel. The apparatus can be adapted to be anchored to a supporting structure so that in the event of an explosion the cage will remain stationary. A method of inflating a tire on a comprises the steps of: a) providing a tire safety cage as above; b) rolling the wheel to be inflated into the cage; c) accessing the valve on the wheel with an air hose through the central opening in the shield and inflating the tire to required air pressure; d) observing the pressurized wheel in the cage through the shield for a period of time to ensure that the tire will safely hold air; and finally, e) rolling the wheel out of the cage.

An improved vehicle wheel tire changing system having a tire mount / dismount head coupled to an articulating tire mount / dismount arm assembly and a tire pressure sensor system which is configured to detect the presence of a tire pressure monitoring system sensor, mounted within a vehicle wheel assembly, prior to altering the mounting of a tire on an associated wheel rim.

An apparatus for processing an un-inflated tire-wheel assembly for forming an inflated tire-wheel assembly is disclosed. The apparatus includes at least a first robotic arm and a second robotic arm forming a pair of robotic arms; an assembling end effecter attached to the first robotic arm; and an inflating end effecter attached to the second robotic arm, wherein the assembling end effecter is indirectly interfaceable with the inflating end effecter by way of the un-inflated tire-wheel assembly. One or more methods are also disclosed. One or more components are also disclosed. One or more systems are also disclosed.

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.

An apparatus for protecting the exterior or polished surface of wheels as tires are removed and placed on the wheel. The apparatus includes a substantially flat base having a plurality of stanchions extending out from the base. Each stanchion has a collar positioned adjacent to the base that includes a diameter greater than the stanchion. The stanchions are sized to fit through the bolt holes of the wheel in order to generally align each stanchion with one of those holes. Each collar is sized to be preferably slightly larger than the average bolt, or lug, hole on the wheel. Additionally, each collar is sized to cover substantially the same area as the lug nut or nut that normally attaches the wheels to the vehicle upon which they are used.

A safety device for inflating an envelope at risk of bursting comprising: a tubular body, a piston element slidably and sealably mounted within at least one inner portion of the tubular body; at least one piston rod integral with the piston element and extending so as to protrude from a first end of the tubular body; an annular bottom member, located in the tubular body or at the first end of the tubular body and suitable for slidably guiding the piston rod and for closing the tubular body whereby delimiting an annular space together with the tubular body and with the piston; removable anchoring device suitable for acting at a protruding end of piston rod and for constraining the piston rod to a support; at least one inlet opening and at least one outlet opening formed in the tubular body at the annular space, in operation said inlet opening being suitable for being connected to a pressurize fluid source and the outlet opening being designed to be connected to the envelope to be pressurized; and a yielding retainer for holding in position the said piston element, so that in case of bursting, the unit formed by the tubular body and the annular bottom member can be moved longitudinally following a bursting impact with respect to the piston element in contrast with the yielding retainer.

A transfer device is provided for transferring tires from a tire conveyor line to a wheel conveyor line. The transfer device includes first and second surfaces rotatable with respect to one another. The first surface can receive tires from the tire conveyor line. A rotating device rotates the first surface to induce movement of the tire to the second surface. The second surface can receive the tire from the first surface and rotate toward the wheel conveyor to position the tire to engage the wheel.

A nozzle for seating a tubeless tire on a rim using pressurized gas includes an outlet, a jet configured to accept pressurized gas and emit a stream of gas through an orifice into a chamber. As the stream of gas enters the chamber, the Venturi effect causes air to enter the chamber through air intake ports and the stream of gas and air from the air intake ports is blown out of the outlet of the nozzle. A system for seating a tubeless tire on a rim includes the nozzle, a tank and a valve configured to control the flow of pressurized gas from the tank to the nozzle. The tire may be seated on the rim by positioning the system so that the air from the nozzle blows into the tire between the bead of the tire and the rim if the valve is opened.

In the method of mounting a pneumatic radial tire comprising a spiral belt and a pair of cross belt members arranged in parallel to each other at both sides of an equatorial plane of the tire and at a given opening space onto a vehicle body, the tire is mounted as a front tire and / or a rear tire so as to contact a portion of the cord in the belt member facing the opening space with ground under a given condition in a forward rotating direction of the tire.

A method of separating the bead of a tire from a rim to which it is mounted in a tire / rim combination. One step of the method involves providing a tire lifting device having a working end including a rigid bead puller and a flexible positioner. Next, a sidewall of the tire is depressed, such as via a roller, in order to produce a gap between the bead and the rim. The working end of the tire lifting device is then inserted into the gap such that the flexible positioner engages the rim and the bead puller engages the bead. Finally, the tire pulling device is moved such that the bead is pulled over the rim.
