Wheel (x2): Load Capacity 500-5000 kg per wheel

Component Specifications

Definition

A wheel is a circular mechanical component that rotates around an axle, typically used in pairs (wheelset) to support vehicle weight, transmit driving and braking forces, and provide directional control. In industrial applications, wheels are precision-engineered to meet specific load capacities, speed ratings, and environmental conditions.

Working Principle

Wheels operate on the principle of rotational motion, converting linear force into circular movement through torque applied at the axle. The wheel-axle system functions as a simple machine that reduces friction between the vehicle and surface, enabling efficient transportation of loads.

Materials

Typically manufactured from forged or cast aluminum alloys (A356-T6, 6061-T6), steel alloys (SAE 1045, 4140), or composite materials. Material selection depends on application requirements including strength-to-weight ratio, corrosion resistance, and thermal properties.

Frequently Asked Questions

What are the main differences between forged and cast wheels?

Forged wheels are created under high pressure, resulting in denser grain structure, higher strength, and lighter weight. Cast wheels are made by pouring molten metal into molds, offering cost-effectiveness for standard applications but with slightly lower strength-to-weight ratios.

How do I determine the correct wheel load capacity for my application?

Calculate total vehicle weight divided by number of wheels, then apply a safety factor of 1.5-2.0. Consider dynamic loads from acceleration, braking, and road conditions. Always consult manufacturer specifications and relevant standards.
