연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A track for in-line tires on a skid steer vehicle, the track includes a continuous loop of links with sidebars and a pin and a barrel, the pin and barrel together forming a hinge between the links and extending between the sidebars. Tire side guides extend upward from the side bars to guide the tires along a pathway over the upward side of the hinges. The opposite side of the hinges engage the ground. The tire side guides can be permanently attached or temporarily fastened to the sidebars at selected positions and moved to other selected positions to con...

1. A track for a skid steer vehicle, comprising:a plurality of links, each of the links having a pin, the pin having a pin axis, a first pin end and a second pin end, a first sidebar extending radially outward from adjacent the first pin end of the pin, a second sidebar extending radially outward from adjacent the second pin end of the pin, the first and second sidebars being radially locked relative to the pin in a substantially spaced apart and parallel relationship, the first sidebar further having an inset-jog directed toward the second sidebar and the second sidebar further having an inset-jog directed toward the first sidebar, a barrel, the barrel having a barrel axis, a first barrel end and a second barrel end, the first barrel end rigidly secured to the first sidebar radially outward from the inset-jog and the second barrel end rigidly secured to the second sidebar radially outward from the inset-jog, such that the barrel is carried spaced apart from and parallel to the pin in an aligned relationship between the first sidebar extending from the pin and the second sidebar extending from the pin, and the barrel of a link capturing a pin of a sequential link between the first and second sidebars of the sequential link to define a barrel-pin hinge between the link and the sequential link, the barrel-pin hinge defining, on a first side, a tire-support for a tire of the skid steer vehicle and defining on an opposite side a ground-engaging support; anda first tire side guide projecting from the first sidebar on the first side of each link and a second tire side guide projecting from the second sidebar on the first side of each link, the first and second tire guides together defining boundaries of a guided pathway for the tire of the skid steer vehicle over the tire-support of the barrel-pin hinge. 2. The track of claim 1 and wherein the links are joined to form a continuous track such that the tire of the skid steer vehicle is sequentially guided over all of the barrel-pin hinges and then sequentially re-encounters all of the barrel-pin hinges. 3. The track of claim 2 and wherein a spacer-link is encountered, the spacer-link having a smaller spaced apart relationship between the pin and the barrel of the spacer-link than the spaced apart relationship between the pin and barrel of the link. 4. The track of claim 3 and wherein the first and second spacer-link sidebars each have a plurality of apertures to connect to a pin, the plurality providing a plurality of selectable spacings between barrel and pin of the spacer-link. 5. The track of claim 1 and wherein the sidebars, pin and barrel are formed of hardened steel. 6. The track of claim 1 and wherein the first tire side guide has an outward axial flare. 7. The track of claim 1 and wherein the second tire side guide has an outward axial flare. 8. The track of claim 1 and wherein the first tire side guide has an outward axial flare, the outward axial flare of the first tire side guide being spaced apart from the tire-support of the link, and the second tire side guide has an outward axial flare, the outward axial of the second tire side guide being spaced apart from the tire-support of the link. 9. The track of claim 1 and wherein the tire side guides are equally spaced from the pin. 10. The track of claim 1 wherein the tire side guide of the first sidebar is positioned between the pin and the offset-jog. 11. The track of claim 1 and wherein the tire side guide of the first sidebar is positioned between the offset-jog and the barrel. 12. The track of claim 1 and wherein the tire side guides are permanently attached to the sidebars. 13. The track of claim 1 and wherein the tire side guides are separable from the sidebars. 14. The track of claim 13 and wherein the sidebars have a plurality of attachment positions for the tire side guides, such that the tire side guides may be attached to a selected one of the plurality of attachment positions to facilitate use with different tire sizes. 15. The track of claim 1 and wherein the barrel of the track is characterized by a flat surface on the barrel directed away from the pin of the link. 16. The track of claim 1 wherein the track is one of a pair of tracks are arranged to sequentially engage the in-line tires in the same sequence. 17. The track of claim 1 and wherein the track has a centerline extending through a midpoint of each hinge, the sum of the spacing from the centerline to the tire side guide on the first sidebar and the spacing from the centerline to the tire side guide on the second side bar determining the tire size which the track is adapted to accommodate. 18. A track system, suitable for use on a skid steer vehicle, the track system being convertible from a first size tire to a second size tire, the second size tire being distinct from the first size tire, the system comprising:a chain, the chain encircling a pair of in-line tires on a side of the skid steer vehicle, the chain comprising a plurality of sequentially hinged links, each of the links having a pin, the pin having a pin axis, a first pin end and a second pin end, a first sidebar extending radially outward from adjacent the first pin end of the pin, a second sidebar extending radially outward from adjacent the second pin end of the pin, the first and second sidebars being radially locked relative to the pin in a substantially spaced apart and parallel relationship, the first sidebar further having an inset-jog directed toward the second sidebar and the second sidebar further having an inset-jog directed toward the first sidebar, a barrel, the barrel having a barrel axis, a first barrel end and a second barrel end, the first barrel end rigidly secured to the first sidebar radially outward from the inset-jog and the second barrel end rigidly secured to the second sidebar radially outward from the inset-jog, such that the barrel is carried spaced apart from and parallel to the pin in an aligned relationship between the first sidebar extending from the pin and the second sidebar extending from the pin, and the barrel of a link encasing a pin of a sequential link between the first and second sidebars of the sequential link to define a barrel-pin hinge between the link and the sequential link, the barrel-pin hinge defining, on a first side, a tire-support for a tire of the skid steer vehicle and defining on an opposite side a ground-engaging support and further defining a center-line of the track through the midpoint of the hinge; anda first tire side guide separably attachable to the first sidebar to project from the first sidebar on the first side of each link with a first separation from the centerline of the track and alternatively separately attachable to a different attachment position with a different spacing from the centerline of the track to provide for a different tire size and a second tire side guide projecting from the second sidebar on the first side of each link, the first and second tire guides together defining a guided pathway for the tire of the skid steer vehicle over the tire-support of the barrel-pin hinge. 19. The convertible track system of claim 18 and wherein the second side bar includes a second separable attachment position for a second tire guide. 20. A method of converting a convertible skid steer track chain, comprising the steps of:providing a chain and separable tire side guides according to claim 14; and,altering the centerline to tire side guide spacing of the track chain.
