Abstract:
A multi air chamber tire 1 includes a partition wall 30 configured to define and form a plurality of air chambers 20 disposed adjacent to each other in an inner cavity of a tire, and a ventilation member 10 provided to the partition wall 30, and configured to connect the plurality of air chambers 20 in a state where ventilation is allowed. The ventilation member 10 allows ventilation between the plurality of air chambers 20 when a predetermined condition is satisfied indicating that fluid is being injected into at least one of the plurality of air chambers 20 from outside of the tire, and the ventilation member 10 shuts off the ventilation between the plurality of air chambers 20 when the predetermined condition is not satisfied.
Abstract:
A method for locking a tire to a wheel rim, includes the steps of mounting a tubular tire locking element on the wheel rim, which tubular locking member is arranged with a valve, which valve is pushed through a hole in the rim; mounting a tire on the rim such that the tire encloses the tubular tire locking element and a pressure chamber is obtained between the tire locking element and the tire; pressurizing the tubular tire locking element via the valve such that it expands, whereby the beads of the tire are pressed against the flanges of the wheel rim; inserting a hollow needle through the tire and into the pressure chamber, which hollow needle is connected to a pressurized air source; pressurizing the pressure chamber to desired pressure, removing the hollow needle; and sealing the hole caused by the needle with sealing fluid or plug.
Abstract:
A pneumatic tires (20FL, 20FR, 20RL, 20RR) each having a plurality of air chambers disposed therein along a tread width direction. An internal pressure control device (100) includes a sensor unit (120) configured to inform a controller (110) that the four-wheel automobile (10) is going as being displaced in the leftward or rightward direction; and the controller (110) configure to change the internal pressures of the plurality of air chambers on the basis of the instruction outputted from the sensor unit (120).
