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.

청구항
▼

1. A vehicle comprising: a frame;a drive system including a drive sprocket operatively connected to an endless belt adapted to be rotated to propel the vehicle;a suspension system connected to the frame to suspend the frame, the suspension system including a plurality of independent driveless suspension modules longitudinally disposed at a distance from the drive sprocket, each suspension module comprising a pivot arm pivotally secured to the frame of the vehicle at a first end thereof about a pivot arm pivot and extending toward a rear portion of the vehicle to pivotally secure a first tandem member at a second end thereof about a first tandem member pivot;a first pair of idler wheels rotatably secured to a first end of the first tandem member;a second tandem member pivotally secured to a second end of the first tandem member thereof about a second tandem member pivot;a second pair of idler wheels rotatably secured to a first end of the second tandem member;a third pair of idler wheels rotatably secured to a second end of the second tandem member, the idler wheels being adapted to operatively secure thereon the endless belt; anda compressible suspension member operatively secured between the pivot arm and the frame to suspend the vehicle and adapted to absorb a load variation applied to the suspension system, the compressible suspension member being actuated when the pivot arm pivots about the pivot arm pivot. 2. The vehicle of claim 1, wherein the pivot arm is pivotally secured to the frame via a pivot arm pivot having an axis substantially orthogonal to a longitudinal direction of the vehicle. 3. The vehicle of claim 1, wherein the pivot arm is adapted to pivot about the pivot arm pivot along a substantially vertical plan substantially parallel with a longitudinal direction of the vehicle. 4. The vehicle of claim 1, wherein the pivot arm pivot is in substantial alignment with an associated compressible suspension member axis. 5. The vehicle of claim 1, wherein the compressible suspension member includes a pneumatic bladder. 6. The vehicle of claim 1, wherein the compressible suspension member includes a hydraulic shock absorber. 7. The vehicle of claim 1, wherein the suspension system includes four suspension system modules. 8. The vehicle of claim 7, wherein two suspension system modules are disposed at a forward portion of the vehicle, respectively on each lateral side of the vehicle, and two suspension system modules are disposed at a rearward portion of the vehicle, respectively on each lateral side of the vehicle, wherein two suspension system modules disposed on the same lateral side of the vehicle have opposed first pair of idler wheels to minimize endless belt tension variations when the suspension is traveling when reacting to the load variation. 9. The vehicle of claim 1, wherein the first tandem member pivot is longitudinally asymmetrically located about a longitudinal length of the first tandem member. 10. The vehicle of claim 1, wherein the second tandem member pivot is longitudinally asymmetrically located about a longitudinal length of the second tandem member. 11. A vehicle suspension system comprising: a plurality of independent driveless suspension modules longitudinally disposed at a distance from a drive sprocket, each suspension module comprising a pivot arm pivotally secured to a frame of the vehicle at a first end thereof about a pivot arm pivot and extending toward a rear portion of the vehicle to pivotally secure a first tandem member at a second end thereof about a first tandem member pivot;a first pair of idler wheels rotatably secured to a first end of the first tandem member;a second tandem member pivotally secured to a second end of the first tandem member thereof about a second tandem member pivot;a second pair of idler wheels rotatably secured to a first end of the second tandem member;a third pair of idler wheels rotatably secured to a second end of the second tandem member, the idler wheels being adapted to operatively secure thereon the endless belt; anda compressible suspension member operatively secured between the pivot arm and the frame to suspend the vehicle and adapted to absorb a load variation applied to the suspension system, the compressible suspension member being actuated when the pivot arm pivots about the pivot arm pivot. 12. The vehicle suspension system of claim 11, wherein the pivot arm is pivotally secured to the frame via a pivot arm pivot having an axis substantially orthogonal to a longitudinal direction of the vehicle. 13. The vehicle suspension system of claim 11, wherein the pivot arm is adapted to pivot about a pivot arm pivot about a substantially vertical plan substantially parallel with a longitudinal direction of the vehicle. 14. The vehicle suspension system of claim 11, wherein the pivot arm pivot is located in substantial alignment with an associated compressible suspension member axis. 15. The vehicle suspension system of claim 11, wherein the compressible suspension member includes a pneumatic bladder. 16. The vehicle suspension system of claim 11, wherein the suspension system comprises four suspension system modules collectively suspending the vehicle. 17. The vehicle suspension system of claim 16, wherein two suspension system modules are disposed at a forward portion of the vehicle, respectively on each lateral side of the vehicle, and two suspension system modules are disposed at a rearward portion of the vehicle, respectively on each lateral side of the vehicle, wherein two suspension system modules disposed on the same lateral side of the vehicle have opposed first pair of idler wheels to minimize endless belt tension variations when the suspension is traveling when reacting to the load variation. 18. The vehicle suspension system of claim 11, wherein the first tandem member axis is longitudinally asymmetrically located on the first tandem member pivot. 19. The vehicle suspension system of claim 11, wherein the second tandem member axis is longitudinally asymmetrically located on the second tandem member pivot. 20. A suspension system kit for a vehicle, the kit comprising: a plurality of independent driveless suspension modules longitudinally disposed at a distance from a drive sprocket, each suspension module comprising a pivot arm adapted to be pivotally secured to a frame of the vehicle at a first end thereof about a pivot arm pivot and extending toward a rear portion of the vehicle to pivotally secure a first tandem member at a second end thereof about a first tandem member pivot;a first pair of idler wheels adapted to be rotatably secured to a first end of the first tandem member;a second tandem member adapted to be pivotally secured to a second end of the first tandem member thereof about a second tandem member pivot;a second pair of idler wheels adapted to be rotatably secured to a first end of the second tandem member;a third pair of idler wheels adapted to be rotatably secured to a second end of the second tandem member, the idler wheels being adapted to rotatably secure thereon the endless belt; anda compressible suspension member adapted to be operatively secured between the pivot arm and the frame to suspend the vehicle and is adapted to absorb a load variation applied to the suspension system when the suspension system kit is mounted on the vehicle, the compressible suspension member being actuated when the pivot arm pivots about the pivot arm pivot.
