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.

초록

A vehicle equipped with a double wishbones and double tandem members suspension system to suspend the vehicle, the double tandem members being operatively interconnected together and adapted to receive idling wheels adapted to support and guide an endless belt thereon to provide significant suspension travel and prevents an endless belt disengagement from the idling wheels. A suspension and a kit thereof are also provided.

1. A vehicle comprising: a frame;a suspension system connected to the frame to suspend the frame, the suspension system includinga first wishbone pivotally secured to the frame of the vehicle at a first end thereof about a first wishbone pivot and pivotally secured to a hub at a second end thereof;a second wishbone pivotally secured to the frame of the vehicle at a first end thereof about a second wishbone pivot and pivotally secured to a hub at a second end thereof;a first tandem member pivotally secured to the hub 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 single idler wheel rotatably secured to a second end of the second tandem member; the idler wheels being adapted to operatively secure thereon an endless belt adapted to be rotated to propel the vehicle; anda suspension member operatively secured between the first wishbone and the frame to suspend the vehicle and adapted to absorb a load variation applied to the suspension system. 2. The vehicle of claim 1, wherein the first wishbone is pivotally secured to the frame via a first wishbone pivot having an axis substantially parallel to a longitudinal direction of the vehicle. 3. The vehicle of claim 1, wherein the hub is adapted to substantially vertically travel along a substantially vertical plan substantially parallel with a longitudinal direction of the vehicle. 4. The vehicle of claim 1, wherein the suspension member extends through the first wishbone. 5. The vehicle of claim 1, wherein the suspension member includes a pneumatic bladder. 6. The vehicle of claim 1, wherein the suspension member includes a hydraulic shock absorber. 7. The vehicle of claim 1, wherein the suspension system is a suspension system module and wherein four suspension system modules are collectively suspending the vehicle. 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 first wishbone pivotally secured to a frame of the vehicle at a first end thereof about a first wishbone pivot and pivotally secured to a hub at a second end thereof;a second wishbone pivotally secured to the frame of the vehicle at a first end thereof about a second wishbone pivot and pivotally secured to a hub at a second end thereof;a first tandem member pivotally secured to the hub 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 single idler wheel rotatably secured to a second end of the second tandem member; the idler wheels being adapted to operatively secure thereon an endless belt adapted to be rotated to propel the vehicle; anda suspension member operatively secured between the first wishbone and the frame to suspend the vehicle and adapted to absorb a load variation applied to the suspension system. 12. The vehicle suspension system of claim 11, wherein the first wishbone is pivotally secured to the frame via a first wishbone pivot having an axis substantially parallel to a longitudinal direction of the vehicle. 13. The vehicle suspension system of claim 11, wherein the hub is adapted to substantially vertically travel about a substantially vertical plan substantially parallel with a longitudinal direction of the vehicle. 14. The vehicle suspension system of claim 11, wherein the suspension member extends through the first wishbone. 15. The vehicle suspension system of claim 11, wherein the suspension member includes a pneumatic bladder. 16. The vehicle suspension system of claim 11, wherein the suspension system is a suspension system module and wherein four suspension system modules are 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.
