Abstract

A device is needed that will provide longboard riders with a truck that is specifically designed for the sharp turns and high speeds they experience throughout their ride. This longboard truck must have a design that is engineered for these purposes and avoids the standard pin and bushing design that is commonly copied from the closely related skateboard truck. This standardized design is outdated, and more importantly, was made to adhere to the skateboard style of riding, consisting primarily of performing tricks with less turning. The longboard truck provides a secure connection point upon the two wheels and the board itself. Additionally, the truck provides a controlled ride by adding additional assistance with turns from leaning the wheels upon the y-axis, unlike the standard skateboard truck design that turns due to motions strictly upon the x-axis. The design enables a larger wheel diameter without sacrificing a low center of gravity compared to a normal truck by relocating the turning pins to the front of the truck instead of directly below it. The truck’s functionality was first evaluated on Solidworks and then 3-D printed to ensure that the motion did not interfere with the structure of the board or the ride. This design offers improved maneuverability while providing a stable ride and a turning radius of just 6 feet.
