Abstract

As the name implies, a simple vehicle can be describe as vehicle which only has a few parts, doesn't have a complicated design, doesn't involve complex machinery, and easy to operate. Although simple, each and every component must be properly built to achieve certain purposes of the vehicle, including the running chassis. It comprises of braking system, suspension system, and steering system. A poorly designed running chassis would cause an uncomfortable ride of the vehicle, instability especially during comer, and eventually low fuel efficiency. The objective of this project was to produce braking system that can give adequate braking, rigid suspension system that can bear the whole weight of the vehicle and give stability to the vehicle and its cargo, and also a rigid and light steering system. They were achieved by conducting research and calculations, experimenting on different setups (trial and error) method and also research about local market availability of the required products. The vehicle's brake was tested both under static and dynamic brake test. Due to all calculations and modifications done to the vehicle, it could be stopped at a 30° inclined slope both using the front brakes and rear brakes individually. Under dynamic test, the vehicle can be stopped in Jess than 5m when the vehicle was driven at a speed of 25 km!h. The brake was also easier and less tiring to operate than the previous configuration thanks to foot operated brakes. Better parts tolerance was achieved due to better design and fabrication process. It reduced the clattering and eases the general operations, especially after proper usage of grease. A newly ergonomic and space efficient driving position was also achieved by simulating it digitally until a satisfying design was achieved. Lastly, the current vehicle can be controlled easily by having a steering ratio of 0.815:1, or also called fast ratio, which is desired for simple vehicle with limited cockpit space.
