Abstract
A structure for standardizing at least one kind of part of an endless track so that parts can be used for the same size of construction vehicles of a plurality of construction vehicle makers, wherein (a) when the part is a link belt, each of a configuration and a dimension of each link, the pin and the bushing is unified over the same size of construction vehicles of a plurality of construction vehicle makers, and (b) when the part is a shoe including four coupling holes, each of a position, a configuration and a size of the four coupling holes is unified over the same size of construction vehicles of the plurality of construction vehicle makers.
Claims10
A structure for standardizing at least one part of an endless track so that said part can be used for a same size of construction vehicles having different structural specifications of a plurality of construction vehicle makers, said at least one part including at least one of (a) a link belt including a pair of links, and a pin and a bushing for coupling adjacent pairs of links, and (b) a shoe coupled to each pair of links of said link belt,
- wherein except a length of said pin, a length of said bushing, at least one of an inside span and an outside span between said pair of links, and a diameter and a position of a shoe bolt hole formed in said pair of links,
- (a) when said at least one part is a link belt, each of a configuration and a dimension in an extending direction of said endless track and two directions perpendicular to said extending direction of said endless track, of each link of said pair of links, said pin and said bushing is unified over said same size of construction vehicles having different structural specifications of said plurality of construction vehicle makers, and
- (b) when said at least one part is a shoe including four coupling holes for coupling said shoe to said pair of links of said link belt, each of a position, a configuration and a size of said four coupling holes is unified over said same size of construction vehicles having different structural specifications of said plurality of construction vehicle makers.
A structure for standardizing at least one part of an endless track so that said part can be used for the same size of construction vehicles having different structural specifications of a plurality of construction vehicle makers, said at least one part including a pair of links, and a pin and a bushing for coupling adjacent pairs of links,
- wherein except a length of said pin, a length of said bushing, and at least one of an inside span and an outside span between said pair of links, each of a configuration and a dimension in an extending direction of said endless track and two directions perpendicular to said extending direction of said endless track, of each link of said pair of links, said pin and said bushing is unified over said same size of construction vehicles having different structural specifications of said plurality of construction vehicle makers.
A structure for standardizing at least one part of an endless track so that said part can be used for the same size of construction vehicles having different structural specifications of a plurality of construction vehicle makers, said at least one part including a shoe coupled to each pair of links of a link belt, said shoe including four coupling holes for coupling said shoe to said pair of links of said link belt,
- wherein each of a position, a configuration and a size of said four coupling holes is unified over said same size of construction vehicles having different structural specifications of said plurality of construction vehicle makers.
