Why is a crown and pinion used in a wheel instead of a bevel gear?

A crown and pinion gear set is typically used in a wheel assembly for its compact design and ability to efficiently transfer power at right angles, which is essential for changing the direction of motion in automotive and machinery applications. Unlike bevel gears, which can be bulkier and less efficient due to their complex tooth geometry, crown and pinion gears offer smoother operation and better load distribution. This makes them ideal for applications where space is limited and reliability is crucial. Additionally, the manufacturing processes for crown and pinion sets can allow for tighter tolerances and improved performance in high-torque situations.
