摘要： A seal (21) comprising a link side lip part (22) abutting against the outer link part (9) of a cover belt (7), a bush side lip part (23) abutting against a bush (11), and an intermediate linking part (24) for linking the lip parts (22, 23). A relation (T2≅ T2'> T1≅ T1') is set, where (T1, T2, T1', T2') are the thickness dimensions at the link side lip part (22), the bush side lip part (23), a link side linking part (24A) and a bush side linking part (24B). Maximum outside diameter part (24C) side of the intermediate linking part (24) is located on the radial outside of the radial intermediate position of the bush side lip part (23). The bush side lip part (23) is pushed entirely and uniformly toward the end face (11A) of the bush (11) by the intermediate linking part (24).

摘要： A drive system for a crawler vehicle includes an endless tread belt consisting of identical tread belt links and a cooperating drive wheel (40). Each link has connecting ears along its forward and aft sides which interdigit with and are hinged to the ears of other links so as to form the belt. Each link also has a guiding cog (13) projecting from its central region, a bearing surface on each lateral side of the guiding cog, aligned drive surfaces on the forward and aft sides of the guiding cog, and a slot (27, 28) in alignment with the drive surfaces. The drive wheel (40) has a plurality of circumferentially spaced teeth (41), two rows of segmented bearing rims (44, 45) alternately offset laterally from each other on the sides of the teeth, the segments of each row being circumferentially spaced and being formed such that the teeth (41) project radially beyond the segments, and a plurality of pockets (42, 43) located between the teeth that open radially outward, and open laterally from the wheel between the rim segments.

摘要： A seal (21) is constituted by an outer lip portion (22) to be held in abutting engagement with an outer link portion (9) of a crawler belt (7), an inner lip portion (23) to be held in abutting engagement with a bush (11), and an interconnecting bridge portion (24) bridged and connected between the outer and inner lip portions (22, 23). The outer lip portion (22) on the side of track link, the inner lip portion (23) on the side of bush, and outer bridge portion (24A) and inner bridge portion (24B) of the interconnecting bridge portion (24) are formed in thicknesses (T1, T2, T1' and T2'), respectively, which are in the relations of (T2 ≒ T2' > T1 ≒ T1'). A maximum outside diameter portion (24C) of the interconnecting bridge portion (24) is located radially outward of a median point between inner and outer peripheral ends of the lip portion (23) on the side of bush. The inner lip portion (23) as a whole is uniformly pressed against an end face (11A) of the bush (11) by the interconnecting bridge portion (24).
