Claims

[Scope of utility model registration request]

A freewheel hub having stepped inner peripheries on the inside and outside in the axial direction, inner and outer tapered roller bearings having outer races fitted to the stepped inner peripheries of the freewheel hub, and these tapered roller bearings. A knuckle spindle having a fitting portion into which the inner race is fitted so as to be slidable in the axial direction, and a threaded portion located outside the fitting portion in the axial direction and having a smaller diameter than the fitting portion; a disc spring that is movable in the axial direction on the outer periphery of the fitting portion of the Knuckle spindle and is disposed on the axially outer side of the outer taper roller bearing and comes into contact with the inner race of the outer taper roller bearing;
The nut includes a nut that is screwed into the threaded portion and tightens the disc spring inward in the axial direction until it is stopped by a stepped surface at the boundary between the fitting portion and the threaded portion of the nutcle spindle. Mounting structure for tapered roller bearings for automobile freewheel hubs.
