A grinding assembly contacts a tire supported by a frame relative to the tire. The grinding assembly includes at least one section, and an axial positioning assembly supporting the at least one section. The axial positioning assembly enables the at least one section to be axially repositioned relative to the tire. The at least one section includes a grinding head, where the grinding head includes a grindstone rotatably supported thereon, the grindstone having rounded shoulders at its axial extremities. The grinding assembly further includes a radial positioning assembly supporting the grinding head for radial movement with respect to the tire.

Tire profile generating machine and related methods

Tire uniformity machine grinding assembly

A tire lubricating system including an applicator assembly having plural applicators movable along a vertical axis to enter the bore of a tire and extensible in a radial direction to contact the beads of the tire and apply a lubricant thereto.

Tire bead lubricating system

A method of positioning a load wheel in a tire uniformity machine to load a tire for testing, the method comprising providing a drive assembly including a drive motor and a drive controller, electrically connected to each other, said drive controller being adapted to switch between analog velocity control and position control; moving the load wheel with the drive motor using analog velocity control; and switching to position control to cause said motor to maintain a selected position of said load wheel without a mechanical brake.

Load wheel drive

A grinder assembly () contacts a tire (T) supported by a frame (F) relative to the tire (T). The grinder assembly () includes at least one section, and a vertical repositioning system () supporting the at least one section. The vertical repositioning system () enables the at least one section to be vertically repositioned relative to the tire (T). The at least one section includes a grinding head (), a radial positioning system () supporting the grinding head () for radial movement with respect to the tire (T), and a tilt adjuster () provided adjacent the grinding head () to provide for pivotal movement thereof. The vertical repositioning system () includes at least one rail extending along the frame (F), and a rail carriage supporting the at least one section on the at least one rail, the rail carriage being vertically repositionable along the at least one rail.

A lateral load testing system for testing a tire mounted on a rotatable spindle, the tire tester including a load assembly, a spindle frame having a support extending therefrom, a spindle housing defining a spindle bore adapted to rotatably receive the spindle, the spindle housing having a support opposite the support on the spindle frame, and a load cell located between the supports, where each support is attached to the load cell. The load cell is in electrical communication with a controller. The spindle frame is moveable to cause the tire to engage the load assembly, whereby lateral forces generated between the load wheel and tire are measured by the load cell and communicated to the controller.

Lateral load tire testing system

A tire uniformity machine for testing a wheel that includes a tire mounted on a rim having a central bore, the tire uniformity machine including a frame defining a machine proper for receiving the reel, a chuck assembly adapted to hold the wheel during testing, the chuck assembly including a protuberance insertably received within the central bore.

Rim chucking machine

A dynamic calibrator in an tire uniformity machine for testing a tire having a chuck assembly for receiving and chucking a tire load cell in sensing relation therewith, the load cell transmitting sensed information to a controller, the dynamic calibrator including a rotatable calibration wheel coupled to the chuck assembly; a motor assembly operatively coupled to the wheel to cause rotation thereof; and a wheel velocity sensing assembly.

Dynamic calibrator

A tire uniformity machine having a framework for receiving a tire to be tested, a rotatable chuck located within the framework and having a spindle driven by a motor directly coupled to the spindle to selectively cause rotation thereof, whereby the tire is chucked within the chuck assembly and caused to rotate by the motor. The motor is disposed in axial alignment with the spindle.

Tire uniformity machine drive assembly

A grinder in a tire uniformity machine having a frame including a first side frame member and a second side frame member, the frame receiving a tire having a central axis for testing, the grinder including a carriage pivotally attached to the first side frame member and a locking assembly adjacent the carriage and the second side frame member selectively coupling the carriage to the second side frame member when the carriage is in the operating position; a grinding head supported on one end of the carriage, the grinding head having at least one grinding stone and at least one motor coupled to the grinding stone capable of causing rotation thereof.

Tire uniformity machine grindstone

A calibration fixture for calibrating load cells in a tire uniformity machine, the tire uniformity machine having a carriage rotatably supporting a load wheel on a first spindle and a second spindle, a first load cell and second load cell in sensing relation to the load wheel and attached to the carriage, at least one of the load cells having a support portion and a sensing portion rotatable within the support portion the calibration fixture including: a fixture member releasably attached to the cover of the load cell; and an adjustment assembly supported by the tire uniformity machine operable with the fixture member to cause movement of the sensing portion relative to the rim.

Load cell conicity calibration apparatus and method

The present invention generally provides an apparatus and method for accurately and rapidly imposing the required average force on a tire by using a drive mechanism, which initially drives the loadwheel carriage to a known average load position for tires of the type under test. This average can be computed based on a single previous test tire or based on an entire population of previously tested tires of the same or similar type.
