Three Part Forged Rear-Bridge House for HOWO A7 8X4

Rear wheel assembly is the complete unit comprising the hub, bearings, and fasteners that mount the wheel to the axle. It is a critical rotating component of the Three part forged rear-bridge house.

Rear wheel hub is the central casting that supports the wheel bearings and provides the mounting flange for the wheel. It is precision‑machined to ensure concentric rotation within the Three part forged rear-bridge house.

Bolt(rear) is a high‑strength wheel stud that secures the wheel to the hub. It is designed to withstand the high shear and tensile loads experienced during cornering and braking.

Hex bolt is a standard metric fastener used throughout the axle assembly for securing covers, brackets, and other components. Its hexagonal head allows accurate torque application.

Hex plug assembly is a threaded plug with a built‑in magnet or seal, used to close inspection or drain ports. It prevents oil leakage and contamination in the Three part forged rear-bridge house.

End plate is a cover that seals the outer end of the axle housing, retaining the lubricant and protecting the bearings from dirt and moisture.

Pin is a cylindrical locating dowel that ensures precise alignment of housing sections and covers. It maintains correct positioning of mating components within the Three part forged rear-bridge house.

Plant gear bracket assembly is the carrier that holds the planetary gears and supports the sun gear. It is a key internal component of the hub reduction system.

Cross axle is a cruciform shaft that supports the planet gears within the differential. It distributes torque evenly to the side gears.

Steel ball8.000 G200b GB308 is a precision‑ground ball used as a check valve or thrust bearing element. Its exact diameter ensures consistent operation.

Plant wheel axle is the shaft that supports the planetary gears within the hub reduction, allowing them to rotate freely and transmit torque.

Roller bearing is a high‑capacity cylindrical roller bearing that supports the axle shaft or hub. It handles heavy radial loads with low friction.

Shim is a thin metal washer used to adjust axial clearance or preload of bearings and gears, ensuring optimal mesh and long life.

Washer is a general‑purpose flat ring that distributes load under fasteners, protecting surfaces and preventing loosening.

Plant wheel(Z=16) is a planetary gear with 16 teeth. It meshes with the sun gear and ring gear to provide the final gear reduction in the hub.

Retainer is a snap ring or circlip that secures bearings and gears in their axial positions, preventing displacement under load.

Sun gear(Z=23) is the central gear of the planetary set, driven by the axle shaft. It transmits power to the planet gears with 23 teeth.

Wheel nut is a hexagonal nut that secures the wheel to the studs. It is torqued to a precise value to ensure safe wheel retention.

Plant bracket retained plate is a cover or retainer that holds the planet gear carrier in position, preventing axial movement.

half axle is a solid shaft that transmits torque from the differential to the wheel hub. It is available in left‑hand and right‑hand versions.

Gear ring is the outer ring gear of the planetary set, fixed to the hub. It provides the reaction torque for the planet gears.

Interior tooth ring (Z=57) is the internal ring gear with 57 teeth, meshing with the planet gears to achieve the desired reduction ratio.

Roller bearing 32222 is a tapered roller bearing used to support the hub or axle shaft. It handles combined radial and thrust loads.

O-ring is an elastomeric seal that prevents oil leakage at joints and between mating surfaces, ensuring a leak‑proof assembly.

Shaft seal ring is a lip seal that prevents lubricant from escaping along the axle shaft while keeping contaminants out.
