What is differential ring and pinion？

The ring and pinion are crucial components of a vehicle's differential, which is responsible for transferring power from the engine to the wheels while allowing them to rotate at different speeds (e.g., during turns). The ring and pinion work together to change the direction of the power flow by transferring torque from the driveshaft to the wheels.

An axle ring and pinion kit typically includes a new ring gear, pinion gear, bearings, seals, and sometimes shims or other small parts required for the installation or replacement of these components. These kits are commonly used for repairing or upgrading a vehicle's differential, especially in cases where the original components have worn out or when gear ratios are being changed to suit specific driving needs, such as off-roading or towing.

Components of axle ring and pinion

• Ring Gear: The ring gear is a large, circular gear that is mounted on the inside of the differential case. It meshes with the pinion gear and is responsible for transferring torque from the driveshaft to the axle shafts, which ultimately drive the wheels. The teeth on the ring gear's outer circumference engage with the teeth of the pinion gear.
• Pinion Gear: The pinion gear is a smaller gear that is connected to the vehicle's driveshaft. It is positioned at a slight angle and meshes with the ring gear. As the pinion gear rotates, it transfers rotational force (torque) to the ring gear, which, in turn, transfers the torque to the axle shafts.

Axle ring and pinion gears are under considerable stress and load, and they require proper lubrication and maintenance. Over time, they may wear out or become damaged, resulting in noise, vibration, and reduced performance. If issues arise with the ring and pinion gears, they may need to be inspected, repaired, or replaced
