Abstract

PURPOSE: To prolong the service life of the device for reducing noise generated around the idler by designing such that the inner pressure of an air tyre functioning as a cushion can be adjusted.
CONSTITUTION: A tube 17 is inserted inside the type 13, the inner pressure of which is adjusted through a pipe 18 and a valve 19 provided within a passage 20. The inner pressure of the type 13 is adjusted so that track links 5, 9 are separated from idler treading surfaces 6, 10 by a constant pushing of a track bush 22 of a track chain 4 outwardly in the radial direction by the outer peripheral surface 21 of the tyre 13 and besides that when a predetermined amount of force is exerted on the track chain 4, the tyre 13 flexes inwardly in the radial direction to permit an engagement between the track links 5, 9 and idler treading surfaces 6, 10. Thus, the metallic tapping noise generated by the direct contact between the link and idler is much reduced. Even when the tyre surface is frictionally consumed to reduce the height thereof up to its limit of use, the tyre 13 can be further used by increasing the inner pressure thereof.
