Title:
PNEUMATIC CIRCUIT OF TIRE TESTING DEVICE, TIRE TESTING DEVICE, AND TIRE TESTING METHOD
Document Type and Number:
WIPO Patent Application WO/2011/074460
Kind Code:
A1
Abstract:
Provided is a tire testing device capable of preventing the change of air pressure caused during a tire test by regulating the temperature of air to be supplied to a tire. A pneumatic circuit (1) of a tire testing device (2) is provided with an air supply source (10) for supplying air to a tire (T) mounted between a pair of rims (6, 7), and a pressure regulation valve (13). The pressure regulation valve (13) regulates the pressure of air to be supplied from the air supply source (10) to the tire (T) to bead air pressure for inflating the tire (T) and mounting the tire to the rims (6, 7) or test air pressure that is lower than the bead air pressure and used during the tire test. The pneumatic circuit (1) is further provided with an air temperature increase mechanism (21) for heating the air to be supplied to the tire at the bead air pressure to a temperature higher than the outside air temperature.
