Weight Optimization of Gears in the Transmission of an All-Terrain Vehicle

Power transmission in automobile plays a major role in the propulsion of an automobile by transferring the power as per the need for the terrain. In an automobile, the power generated by the engine is low in torque but an automobile requires a high amount of torque in comparison to the supplied torque. How can this be achieved? This is achieved with the help of different types of torque multipliers, one of the most common methods is the use of gears. What purpose do the gears serve? Gears can be used to multiply the torque or speed depending upon the gear ratio. With the help of gears, the power is transferred to the drive shaft or directly to the half shaft and then to the wheels. This increased amount of torque moves the vehicle in the initial stage of motion from a static position. During the motion of the gears, they encounter different kinds of forces like bending and dynamic loading for which they must have high strength and endurance limit. In most of the cases, the conventional design of gears is made neglecting the possible optimization options in terms of weight of the gears, since it is believed that higher the amount of material a component carries greater is the strength of that particular component, but at the same time it increases the weight drastically, which increases the inertia required to move the components and this directly reduces the efficiency of the whole system. The system proposed below, works on this issue and consequently leads to increased efficiency.
