Do the small steel balls in the axle increase or decrease friction?
1 Answers
Small steel balls in the axle can reduce friction. Automotive bearings are fundamental components in the vehicle's transmission system, bearing both axial and radial loads, making them crucial parts. Automotive bearings constitute a significant portion of the bearing industry, including wheel hub bearings, air conditioning fan bearings, and pulley bearings. Bearings primarily serve two functions: 1. Maintaining steering flexibility: They ensure that the shock absorber rotates with the wheel during steering, maintaining steering agility. 2. Shock absorption: The outer ring of the pressure bearing is made of rubber, providing a flexible connection between the vehicle body and the shock absorber. This prevents vibrations from uneven road surfaces from being transmitted through the shock absorber to the vehicle body during driving.
