DESIGN & FABRICATION OF SPRING -LESS SUSPENSION WITH BEVEL GEAR

Abstract

The proposed spring-less suspension system integrates an oscillating mechanism with a differential system. The differential consists of a gear train with three driving shafts and  operates on the principle that the rotational speed of one shaft equals the average speed of the other two, or a fixed multiple of that average. Oscillation refers to the periodic or regular movement of an object. The main frame of the system is primarily constructed from aluminum sheets, while the tire-supporting frame is designed to swivel freely. The differential is mounted on this same frame. A motor powers the differential mechanism, transforming it into the driving component. Bevel gears on both sides connect the driving gear to the motor driver, with each gear having two wheels attached on either side. Each wheel is independently powered by its own motor. The motor driver ensures smooth rotation of the wheels and gears, while the oscillating function enables the vehicle to traverse rough terrain effectively. The system is controlled via an ESP32 Cam Car Wi-Fi module, offering seamless remote management. This innovative suspension system eliminates the need for traditional springs by combining an oscillating mechanism with a differential gear train. The differential, characterized by its ability to distribute rotational speeds proportionally, works in conjunction with the oscillation to maintain vehicle stability and adaptability on uneven surfaces. The aluminum frame, coupled with independent wheel motors, ensures a lightweight yet robust structure, making it an efficient and versatile solution for challenging terrains.
