Specification

Description:FIELD OF THE INVENTION
This invention relates to bicycle engineering and eco-friendly transportation technology, focusing on a two-wheel-drive (2x2) bicycle that uses human power to drive both the front and rear wheels. Designed for enhanced stability and traction, the invention addresses limitations in traditional bicycles when navigating through rough terrain, mud, and steep inclines.
BACKGROUND OF THE INVENTION
Traditional bicycles are designed to be powered by pedaling, which typically transfers power to the rear wheel only. While efficient on smooth, paved surfaces, this single-wheel drive design poses challenges on rough or slippery terrains, where the front wheel often lacks sufficient traction and control. When riding on muddy or inclined roads, the likelihood of the bicycle slipping increases due to insufficient power distributed to the front wheel. This invention addresses these challenges by incorporating a dual-drive system, where the same pedaling force powers both the front and rear wheels, enhancing grip, stability, and overall control. By using a 2x2 drive mechanism, this bicycle improves traction and reduces slippage, providing a safer and more versatile riding experience across various terrains.

The Eco-friendly 2x2 Human-Powered Bicycle is designed with a dual-drive mechanism that enables the rider to propel both wheels simultaneously, enhancing stability and control. The design consists of a primary power transfer system that drives the rear wheel and an additional mechanism to transfer pedaling power to the front wheel. The rear-wheel power transfer mechanism includes a pedal-connected chain that engages with a rear sprocket. When the rider pedals, the force is transmitted directly to the rear wheel, enabling propulsion.
To drive the front wheel, an advanced power transfer system involving sprockets, chains, universal joints, and bevel gears is used. A secondary sprocket attached to the pedal connects to another sprocket through a chain. This sprocket is linked to a bevel gear, which changes the direction of power by 90 degrees. The bevel gear connects to a propeller shaft via a universal joint, ensuring that rotational movement is smoothly transmitted despite possible angular changes. The propeller shaft then extends towards the front wheel, where it is connected to another universal joint and a bevel gear assembly. The bevel gear at the front wheel converts the rotational movement back to align with the front wheel's direction, effectively transferring pedaling power to the front sprocket through another chain connection.
This dual-drive mechanism enhances the bicycle's performance on various terrains by providing consistent power to both wheels. The front-wheel drive reduces the risk of slippage, particularly on muddy or inclined surfaces, while the rear-wheel drive maintains stability and control. The bicycle's dual traction capabilities enable it to handle challenging environments, including soft sand, rocky paths, and steep inclines. Additionally, the human-powered design ensures that the bicycle remains environmentally friendly, as it does not rely on fossil fuels or electrical power.
The bicycle frame is designed to support the additional components of the dual-drive system, ensuring structural integrity and ease of pedaling. The system's universal joints and bevel gears are made from durable materials to withstand the forces generated during pedaling. The entire assembly is lightweight and efficient, allowing riders to enjoy enhanced stability without a significant increase in pedaling effort.
