| Summary: | 碩士 === 國立臺灣科技大學 === 機械工程系 === 97 === Prior team which research tilting three wheeled vehicle already have several prototypes. But it not perfectly. When vehicle tilting on a slow speed. On this state ,tread of vehicle will be change. It cause driver cannot go back perpendicular state, and decrease control performance. Also second generation of vehicle cannot tilt at turns like a two wheeler, hence raise the danger of rolling over. This research will improve the tread of vehicle problem and raise vehicle control performance.
The objective of this research is to improve upon the second generation of tilting three wheeled vehicle. This research takes full advantage of the Pro ENGINEER Wildfire 3.0 on design of the vechicle. Reduce of testing with actual materials has consumed a great deal of time and budget. From the simulation results, the mechanic parts can be repeatedly modified with ease. Only after the entire structure can meet the demands of the design, the actual work of assembly and test ride is taken place to physically verified the new design.
In order to improve tread of vehicle problem. We change original swing-linkage to four-bar linkage. And improve second 2F/1R vehicle’s steering ratio problem. The test ride reveals the safety and controllability of the vehicle is greatly enhanced. The driver can control the tilting angle with ease, and turn or dodge obstacles entirely without concerns of rollover.
