Automobile Hub Bearing

Definition

To connect the wheel and axle, to withstand the weight of the vehicle and the various forces generated during the driving process, and to ensure that the wheel can rotate smoothly.

Features

- High load capacity: able to withstand the weight of the vehicle and the dynamic load during driving.
- High precision: ensure the smooth rotation of the wheel, reduce vibration and noise.
- Good sealing: prevent dust, water and impurities from entering the bearing, extend the service life.
- High reliability: it can work stably in all kinds of road conditions and harsh environments.

Categories

- First generation hub bearings: consisting of two sets of tapered roller bearings or angular contact ball bearings.
- Second generation hub bearings: the two sets of bearings of the first generation are integrated in a single unit with mounting parts such as flanges.
- The third generation of hub bearings: on the basis of the second generation, sensors and other functional components are added to achieve intelligence.

Basic Parameters

- Inside diameter: matches the diameter of the axle.
- Outer diameter: suitable for the installation size of the wheel hub.
- Width: determines the bearing capacity and installation space.
- Rated dynamic load and rated static load: reflects the bearing capacity.
- Limit speed: indicates the highest speed that the bearing can withstand.

How It Works

The inner ring of the automobile hub bearing is connected with the axle, and the outer ring is connected with the hub. When the wheel rotates, the friction resistance is reduced by rolling between the inner and outer rings through the rolling body (usually a steel ball or roller), so that the wheel can rotate smoothly. At the same time, the bearings bear the forces from the vehicle weight, acceleration, braking and steering.

Application Field

- All types of vehicles: passenger cars, commercial vehicles, off-road vehicles, etc.
- New energy vehicles: such as electric vehicles, hybrid vehicles, etc.
- Special vehicles: such as engineering vehicles, fire engines, ambulances, etc.
