Abstract

PURPOSE: To eliminate noises due to engagement between sprockets and a pin, by forming connection portions where links, to which a shoe is fixed, are mutually connected in plain-bearing structure, and by making up a lubricating oil path communicated with the connection portions in the pin, in this truck manufactured by mutually connecting said links by means of the pin.
CONSTITUTION: One link 2 and the other link 2' are each fixed to a shoe 3 by means of bolts 9, and the links 2, 2' are severally connected by means of a pin 1. Plain bearings 4 are mounted to the pin 1 of connection portions A so as to resist load in the axial direction while the pin 1 is hollowly built up, and the hollow portion is used as a lubricating oil path, an oil reservoir 5. The oil reservoir 5 and the connection portions A are communicated by means of oil holes 7, and lubricating oil fed to the oil reservoir 5 is supplied to the connection portions A and the plain bearings 4 from the oil holes 7. Thus, impact in the case when the pin 1 and sprockets engage can be damped because the squeeze damping effect of oil is gained by the formation of oil films at the connection portions A.
