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 band track for a tracked vehicle having enhanced resistance to mines includes a plurality of track pad units disposed on the bearing surface of the track band. The track pad units have extended end walls of sufficient height to distance the vulnerable portion of the band track from the shearing force of an exploding mine. These end walls are sufficiently strong to support the vehicle as it traverses terrain, but are configured to collapse in controlled manner under the force of an exploding mine. Such explosion forces a specifically configured front end wall of a trailing track pad to engage the matingly configured end wall of the leading track pad. The resulting mating juxtaposition of the adjacent end walls forms a relatively continuous physical barrier protecting the vulnerable section of the band track from shrapnel and other entrained ejecta of the explosion.

What is claimed is: 1. In a band track for a tracked vehicle, the improvement comprising a track pad disposed on an outer surface of a band body of the band track, the track pad comprising: a plurality of track pad units, each unit having a bearing surface, a front end wall contiguous between the outer surface of the band track and a front edge of the bearing surface, and a rear end wall disposed opposite the front end wall contiguous between the outer surface of the track body and a back edge of the bearing surface, the front and rear end walls being of only such width sufficient to support the vehicle as it traverses terrain but sufficiently narrow to collapse under the force of an exploding mine, wherein the front end wall curves in an are which is convex relative to the forward direction of movement of the track and the rear end wall curves in an arc which is concave relative to the forward direction of movement of the track, the arcs of the front and rear end walls configured to matingly nest with each other under the compressive force of the explosion of a mine. 2. The band track of claim 1 wherein the front and rear end walls are of height sufficient to minimize the explosive effect of a mine on the outer surface of the track band. 3. The band track of claim 1 wherein the front and rear end walls are arcuately curved as each extends from the bearing surface to the outer surface of the track band, whereby the shear force of the explosion of a mine is dispersed away from the outer surface. 4. The band track of claim 1 wherein the track pad further comprises sealed side walls which, in combination with a sealed interior face of the bearing surface, and a sealed interior face of the band body, and the front and rear end walls, form a track pad cavity having an enclosed volume capable of being filled with with one of either a gaseous fluid or a liquid fluid. 5. The band track of claim 4 wherein said one of either a gaseous fluid or a liquid fluid filling the enclosed volume of the track pad cavity is pressurized. 6. The band track of claim 1 wherein the track pad further comprises at least one between an interior side of the bearing surface an the rear end wall, and extending between an interior side of the bearing surface and an exterior side of the band body. 7. The band track of claim 1 wherein the bearing surface may be selectively textured to increase fraction of the bearing surface over the prevalent terrain condition. 8. The band track of claim 1 wherein the bearing surface may be selectively studded to increase fraction of the bearing surface over the prevalent terrain condition. 9. In a wheel and band track assembly for a tracked vehicle, comprising a drive wheel, an idler wheel and at least one road wheel around all of which the band track is entrained, such that rotation of the drive wheel drives rotation of the band track around said entrained drive wheel, idler wheel, and road wheels, in turn driving the vehicle, the improvement comprising a track pad disposed on an outer surface of a band body of the band track, the track pad comprising: a plurality of track pad units, each unit having a bearing surface, a front end wall contiguous between the outer surface of the band track and a front edge of the bearing surface, and a rear end wall disposed opposite the front end wall contiguous between the outer surface of the track body and a back edge of the bearing surface, the front and rear end walls being of only such thickness sufficient to support the vehicle as it traverses terrain but sufficiently narrow to collapse under the force of an exiting mine, wherein the front end wall curves in an arc which is convex relative to the forward direction of movement of the track and the rear end wall curves in an arc which is concave relative to the forward direction of movement of the track, the arcs of each end wall configured to matingly nest with each other under the compressive force of said exploding mine. 10. The band track of claim 9 wherein the track pad further comprises sealed side walls which, in combination with a sealed interior face of the bearing surface, and a sealed interior face of the band body, and the front and rear end walls, form a track pad cavity having an enclosed volume capable of being filled with one of either a gaseous fluid or a liquid fluid. 11. The band track of claim 10 wherein said one of either a gaseous fluid or a liquid fluid filling the enclosed volume of the track pad cavity is pressurized. 12. The band track of claim 9 wherein the track pad further comprises at least one interior support wall located between the front end wall and the rear end wall, and extending between an interior side of the bearing surface and an exterior side of the band body. 13. The band track of claim 9 wherein the bearing surface may be selectively textured to increase traction of the bearing surface over prevalent terrain condition. 14. The band track of claim 9 wherein the bearing surface may be selectively studded to increase traction of the bearing surface over prevalent terrain condition. 15. In a band track for a tracked vehicle, the improvement comprising a track pad disposed on an outer surface of a band body of the band track, the track pad comprising: a plurality of track pad units, each unit having a bearing surface, a front end wall contiguous between the outer surface of the band track and a front edge of the bearing surface, and a rear end wall disposed opposite the front end wall contiguous between the outer surface of the track body and a back edge of the bearing surface, the front and rear end walls being of only such width sufficient to support the vehicle as it traverses terrain but sufficiently narrow to collapse under the force of an exploding mine, wherein the front end wall curves in an arc which is convex relative to the forward direction of movement of the track and the rear end wall curves in an arc which is concave relative to the forward direction of movement of the track, the arcs of the front and rear end walls configured to matingly engage each other under the compressive force of the explosion of a mine. 16. The band track of claim 15 wherein the front and rear end walls are of height sufficient to minimize the explosive effect of a mine on the outer surface of the track band. 17. The band track of claim 15 wherein the front and rear end walls are arcuately curved as each extends from the bearing surface to the outer surface of the track band, whereby the shear force of the explosion of a mine is dispersed away from the outer surface. 18. The band track of claim 15 wherein the track pad further comprises sealed side walls which, in combination with a sealed interior face of the bearing surface, and a sealed interior face of the band body, and the front and rear end walls, form a track pad cavity having an enclosed volume capable of being filled with one of either a gaseous fluid or a liquid fluid. 19. The band track of claim 15 wherein the track pad further comprises at least one interior support wall located between the front end wall and the rear end wall, and extending between an interior side of the bearing surface and an exterior side of the band body. 20.
