Juria CAD Model, Description of Parts, and Assembly Details

This is one of the initial 3D renderings, showcasing the key components that make up the Juria. Each component serves a specific purpose, contributing to the final Juria design.

The battery will be mounted in the center of the rig and will power both motors. Placing the battery in the center helps to distribute weight more evenly across the vehicle or device, improving balance and stability. In the Juria, which will prioritize safety and practicality, this can lead to better handling and reduced body roll during turns. A centrally mounted battery also lowers the center of gravity, improving overall vehicle dynamics, and making it more stable and safer. The vehicle's center is often the safest location in the event of a collision or damage from the underside. While traversing through rugged trail terrain, mounting the battery in the center protects it from damage, which is crucial since batteries can be hazardous if ruptured.

The front wheel will be able to gyrate around itself and will provide extra maneuverability as opposed to the original Wike which usually has a stationary front wheel. The front wheel is typically responsible for steering the vehicle. By allowing the front wheel to move, the driver can control the direction of the Juria. Without a steerable front wheel, the Juria would be difficult to maneuver and change directions effectively. This is especially crucial in a trail environment where navigating around boulders and outstanding roots is very common. A movable front wheel makes the vehicle easier to handle, particularly at lower speeds or in tight spaces. This is important for the overall usability and safety of the Juria. Furthermore, many three-wheeled vehicles, like trikes or certain types of motorcycles, are designed with one wheel at the front and two at the rear. The front wheel typically does most or all of the steering work, which allows the vehicle to be more compact, efficient, and easier to control.

The new Juria will have a reinforced chassis and mount for the wheel as opposed to the conventional Wike. Three-wheeled vehicles often have a different weight distribution compared to four-wheeled vehicles, with more stress placed on fewer points of the chassis. A reinforced chassis helps distribute these loads more evenly, preventing structural failure. The fewer number of wheels means that the chassis needs to bear more stress, particularly at the points where the wheels connect. Reinforcement ensures that these areas can handle the increased loads. The angled shape of the front chassis also allows for a streamline design as opposed to a straight aluminum piece that would likely move the center of mass further to the rear and cause instability on inclined terrain.

The L-faster 24V 500W Motor will be utilized to power the Juria. A 500-watt motor provides sufficient power to propel the Juria at a reasonable speed (typically 4-8 mph) and to handle inclines or rough terrain. This level of power strikes a balance between ensuring adequate performance while maintaining battery efficiency. While higher-wattage motors could offer more power, they would also drain the battery faster. A 500-watt motor offers a good compromise, providing the necessary power while optimizing battery life for longer usage between charges. Mounting the motor close to or directly on the rear wheel allows for a direct drive system, where the motor drives the wheel directly without the need for complex transmission systems. This increases efficiency by reducing energy losses and mechanical complexity. The rear wheels also typically bear more of the Juria’s weight, especially during acceleration or when climbing inclines. By positioning the motor at the rear, it can more effectively transfer power to the wheels, improving traction and stability. Placing the motor in the rear helps in balancing the overall weight distribution of the Juria. This is important for maintaining stability and preventing tipping, especially when navigating slopes or uneven terrain. Furthermore, the rear-mounted motor provides a smoother and more controlled ride, as the power delivery is more direct and predictable. This is crucial for user comfort, especially for individuals who may spend extended periods in the Juria over long stretches of trail.

The motor will be mounted on a steel plate that will be attached to the rear part of the chassis. The plate ensures that the motor is securely fastened to the chassis, distributing the forces and stresses generated by the motor evenly across a larger area. This reduces the risk of damage to the motor or the Juria's frame. The mounting plate also incorporates features and materials that help dampen vibrations generated by the motor. This reduces the transmission of vibrations to the Juria's frame, improving user comfort and minimizing noise.

The motor will also be directly attached to a smaller adjustable plate that will utilize two screws to move the motor in any direction in relation to the positioning of the chain. An adjustable mounting plate allows for fine-tuning the position of the motor relative to the drive components (e.g., wheels, chain, or sprockets). Proper alignment is crucial to ensure efficient power transfer, minimize wear and tear, and prevent issues like misalignment that could cause excessive noise, vibration, or even damage. Adequate tension needs to remain in the chain and the motor in order to drive the gears and power the Juria.
