Problems solved by technology

If there is such a deviation in the rotational torque, the smooth rotation of the driving body to the hub shaft will not be obtained, which will deteriorate the feel when turning the hub shaft or the driving body by hand, and it will be difficult to have a high-end feeling.

Abstract

The bicycle hub of the present invention can suppress variation in the rotational moment of the drive body. The rear hub (1) has a hub shaft (5), a hub body (6), first and second rolling bearings (10, 11), a driving body (7), a one-way overrunning clutch (8), a third rolling bearing (12) , the fourth rolling bearing (13), the bushing (14) and the pushing member (15). The hub shaft is mounted on the frame. The hub body is arranged on the outer peripheral side of the hub shaft. The first and second rolling bearings are axially separated and arranged between the hub body and the hub shaft. The driving body and the hub body are arranged concentrically, and the sprocket group can be installed. The one-way overrunning clutch only transmits the rotation of the driving body in one direction to the hub body. The third rolling bearing is arranged in the gap between the driving body and the hub shaft, and is in clearance fit with the inner peripheral part of the driving body, and its inner ring is in static fit with the outer peripheral surface of the hub shaft. The fourth rolling bearing is disposed axially outward of the third bearing. The bushing is arranged between the third bearing and the fourth bearing. The pressing member is screwed into the hub shaft, and presses the inner ring of the fourth rolling bearing.

Description

technical field [0001] The present invention relates to a bicycle hub, and more particularly to a bicycle rear hub mounted on a frame of a bicycle, arranged at the center of the wheel, and capable of mounting a sprocket. Background technique [0002] Generally, the hub provided at the central portion of the bicycle wheel has a hub shaft that is detachably and non-rotatably mounted on the frame of the bicycle, a hub body that is freely rotatably mounted on the hub shaft, and a hub body that is freely rotatable relative to the hub shaft. Bearings supporting the hub body. In the case of a rear hub (flywheel hub) mounted on the rear wheel of a bicycle, it also has a drive body rotatably mounted on the hub shaft, and a one-way overrunning clutch that transmits the rotation of the drive body in one direction (the bicycle travel direction). In this known bicycle hub, a pair of rolling bearings are mounted between the drive body and the hub shaft with a gap. In the rolling bearing...
