Introduction

A rear wheel hub assembly is an integral part of a vehicle's suspension and steering system. It serves as the mounting assembly for the wheel and consists of a central housing, bearings, and a hub. It is designed to support the weight of the vehicle and facilitate smooth wheel rotation.

Components of a Rear Wheel Hub Assembly

The key components of a rear wheel hub assembly include:

  • Hub: The central part that attaches to the wheel and rotates with it.
  • Bearings: These reduce friction between the hub and its housing, allowing for smooth wheel rotation.
  • Wheel Flange: Connects the hub to the brake rotor and wheel.
  • ABS sensors and tone ring: Integrated into some assemblies to provide data to the vehicle's ABS system.

Functionality

The primary functionality of a rear wheel hub assembly includes:

  • Wheel Attachment: The hub serves as a mounting point for the wheel and is bolted onto the axle.
  • Weight Support: It supports the vehicle's weight and helps in maintaining proper tire alignment.
  • Rotation Facilitation: The bearings within the hub reduce friction, thus aiding in smooth wheel rotation.
  • Data Provision: Where equipped, ABS sensors within the hub assembly provide critical wheel speed data for braking efficiency.

Numerical Specifications

The design and performance specifications of a rear wheel hub assembly can vary, but common parameters include:

  • Load Capacity: Typically ranges from 1,500 to 2,500 kg per wheel, depending on vehicle type.
  • Bearing Diameter: Usually ranges between 70 mm to 150 mm to accommodate different axle sizes.
  • Material Composition: Majority made from high-strength steel or aluminum alloys, providing a balance of durability and weight.
  • Tolerances: Machining tolerances are often within ±0.01 mm to ensure precise fit and function.
