TRACK BELT FOR SNOWMOBILE

摘要

PROBLEM TO BE SOLVED: To provide a track belt for snowmobiles that can improve their high- speed travel performance via an arrangement which offsets differential weight caused by the presence and absence of metal guides on sliding metal fittings attached to them by the differential original weight between two types of tractive projection and thus via suppression of dispersion of centrifugal forces by vibration sources during high-speed travel. SOLUTION: Lines of tractive projections 13x embedded with a lateral rigid member mounted with sliding metal fittings 15a alternate with lines of tractive projections 13y embedded with a lateral rigid member mounted with sliding metal fittings 15b having metal guides. The volume of each tractive projection line 13y is set to make almost no difference in weight from each tractive projection line 13x, or the projected portions of each tractive projection line 13y where the crimped lateral rigid member is provided with the sliding metal fittings 15b and metal guides are partly whittled down to the same effect.
