A bevel differential is a type of differential that utilizes bevel gears as its main components. Unlike a standard differential that typically uses spur gears, which are parallel, bevel differentials use bevel gears to allow the input and output shafts to be at right angles to each other. This design is particularly useful in applications where space constraints or specific mechanical configurations require a 90-degree angle between the shafts.
In automotive engineering, for example, bevel differentials can be found in certain rear-wheel-drive vehicles where the engine’s longitudinal powertrain layout necessitates a right-angle change in direction from the driveshaft to the rear axle. This configuration allows for efficient power transmission and torque distribution while maintaining a compact design.
