A track member for a track of a vehicle of the tracked type, which comprises a pin, a bushing associated with and rotatable relative to the pin, and first and second inner and outer track link assemblies associated with and rotatable relative to the pin, and arranged on opposite sides of the bushing
A track member for a track of a vehicle of the tracked type, which comprises a pin, a bushing associated with and rotatable relative to the pin, and first and second inner and outer track link assemblies associated with and rotatable relative to the pin, and arranged on opposite sides of the bushing. The first inner track link assembly is arranged between the first outer track link assembly and the bushing, and the second inner track assembly is arranged between the second outer track link assembly and the bushing. The first and second inner track assemblies each include a ring rotatable relative to the pin. The track member further includes first and second inner and outer gasket seats which house respective gaskets. The inner and outer gaskets are orientated so that they act against side surfaces of the rings.

1. A track member for a track of a vehicle of the tracked type, comprising: a pin;a bushing associated to said pin and rotatable relative to the pin;a first inner track link assembly and a second inner track link assembly associated to said pin and rotatable relative to the latter, respectively arra
1. A track member for a track of a vehicle of the tracked type, comprising: a pin;a bushing associated to said pin and rotatable relative to the pin;a first inner track link assembly and a second inner track link assembly associated to said pin and rotatable relative to the latter, respectively arranged on two opposite sides of said bushing;a first outer track link assembly and a second outer track link assembly associated to said pin and rotatingly integral to the pin,in which said first inner track link assembly is arranged between said first outer track link assembly and said bushing, and in which said second inner track link assembly is arranged between said second outer track link assembly and said bushing, andwhereinsaid first inner track link assembly comprises a first ring rotatable relative to said pin, and a first inner track link rotatably integral to said first ring, and wherein said second inner track link assembly comprises a second ring rotatable relative to said pin and a second inner track link rotatably integral to said second ring;said track member further comprises a first and a second inner gasket seats, wherein said first inner gasket seat is defined by said first ring, said pin, and said bushing, said first inner gasket seat housing a first inner gasket therein, and said second inner gasket seat housing a second inner gasket therein;said track member further comprises a first outer gasket seat defined by said pin, said first ring, and said first outer track link assembly, and a second outer gasket seat defined by said pin, said second ring, and said second outer track link assembly, said first outer gasket seat housing a first outer gasket therein, and said second outer gasket seat housing a second outer gasket therein;wherein the first inner gasket is oriented so that it acts against a first side surface of the first ring, and the first outer gasket is oriented so that it acts against a second side surface of the first ring, and the second inner gasket is oriented so that it acts against a first side surface of the second ring, and the second outer gasket is oriented so that it acts against a second side surface of the second ring; andsaid first inner gasket seat and said second inner gasket seat are respectively partially defined in a first and in a second recessed portions of said bushing. 2. The track member according to claim 1, in which said pin includes a pin extended portion, and said pin extended portion and said pin have cylindrical configurations, said pin extended portion being substantially coaxial to said pin and having a greater diameter than the pin diameter, so that said first and said second abutting surfaces have annular configurations. 3. The track member according to claim 1, wherein said first ring and second ring comprise one or more channels for the passage of lubricant. 4. The track member according to claim 1, comprising a first inner spacer member arranged in said first inner gasket seat between said bushing and said first ring, and a second inner spacer member arranged in said second inner gasket seat between said bushing and said second ring. 5. The track member according to claim 4, wherein said one or more channels are longitudinal or helical. 6. The track member according to claim 1, comprising a first outer gasket seat defined by said pin, said first ring, and said first outer track link assembly, and a second outer gasket seat defined by said pin, said second ring, and said second outer track link assembly, said first outer gasket seat housing a first outer gasket therein, and said second outer gasket seat housing a second outer gasket, therein. 7. The track member according to claim 1, comprising a first outer spacer member arranged in said first outer gasket seat between said first outer track link assembly and said first ring, and a second outer spacer member arranged in said second outer gasket seat between said second outer-track link assembly and said second ring. 8. The track member according to claim 1, comprising a first outer gasket seat defined by said pin, said first ring, and said first outer track link assembly, and a second outer gasket seat defined by said pin, said second ring, and said second outer track link assembly, said first outer gasket seat housing a first retaining ring therein having a first auxiliary outer gasket seat that houses a first outer gasket therein, and said second outer gasket seat housing a second retaining ring therein having a second auxiliary outer gasket seat that houses a second outer gasket therein. 9. The track member according to claim 1, wherein said first and second retaining rings are connected to said pin by interference, and abut in the axial direction against said first and second outer track link assemblies, respectively. 10. The track member according to claim 8, wherein said first and second retaining rings act as spacer members between the first outer track link assembly and the first ring, and between the second outer track link assembly and the second ring, respectively. 11. The track member according to claim 8, comprising a first and a second outer spacer members arranged within said first and said second auxiliary outer gasket seats of said first and second retaining rings respectively. 12. The track member according to claim 1, wherein the bushing has projecting portions delimiting said first and second inner gasket seat. 13. The track member according to claim 1, wherein said projecting portions are inserted in recessed portions of the inner track links. 14. A track comprising one or more track members according to claim 1.
