HUB UNIT FOR SUPPORTING DRIVE WHEEL
Document Type and Number:
Japanese Patent JP2010069926
Kind Code:
A
Abstract:
To provide a hub unit for supporting a drive wheel, capable of attaining high installability and high rigidity by devising its shape.
A female spline 23 of a hub ring 12 is divided into a first female spline 40 nearer to an outer end in the axial direction and a second female spline 41 nearer to an inner end in the axial direction. The first female spline 40 is formed to be fitted onto a female spline 33 of a spline shaft 32 and the second female spline 41 is formed into a taper shape so that clearances between the spline shaft 32 and the female spline 33 in the diametrical and peripheral directions gradually increase from a boundary position B to the first female spline 40 toward an inner end position C in the axial direction.
