AUTOMOTIVE HUB DESIGN--PT. 2

Double-row angular contact ball bearings for car wheels are discussed as originated by SKF, an international ball and roller bearing manufacturer. Advantages of this bearing over its predecessor, the single-row bearing, are mentioned: preset clearance, making inadvertent preloading impossible; integral seals protecting the bearing during handling and mounting; sealed bearing containing the correct quantity and quality of grease; nylon cages allowing for reduced noise and lubrication demand; axial compactness; reduced parts; and positively locked inner rings. The three generations of double-row ball bearings now produced by SKF and examples of their application are pictured and described. Generation 1 hub bearings are mounted on hub extensions, thereby relieving the CV-joint shaft of all wheel loads. They can be used in driven and non-driven wheels. Generation 2 bearings, fully interchangeable with Generation 1 bearings, have an integral flange on the outer ring for securing to suspension or wheel. The advance is simplicity; only a stub axle and clamping nuts are needed for mounting. Generation 3 bearings are hub units, structural members of the vehicle suspension. Classed as safety critical assemblies, they have to meet very exacting specifications. Extensive development testing resulted in the establishment of a range of five hub units which meet the needs of most European cars.
