Hub with a toothed disk freewheel

摘要

Hub for two-wheeled vehicles having a hub axle and a hub body and a rotor and with a toothed disk freewheel comprising a pair of interacting engagement components each comprising one axial toothing. The engagement components are biased in the engagement position via a biasing device. The one of the engagement components is received at the hub body to be non-rotatable and axially displaceable and the other of the engagement components is provided non-rotatable at the rotor for transmitting a rotary motion from the rotor to the hub body in the engagement position of the two engagement components. At least one engagement component is configured as a toothed disk and is provided with the axial toothing and has an axial width which is at least the size of half the outer radius of the axial toothing.

1. A hub for at least partially muscle-powered vehicles, comprising:
a hub axle, a hub body, a rotor and a toothed disk freewheel comprising a pair of interacting engagement components each comprising at least one axial toothing, the engagement components being biased in an engagement position via two biasing devices; one of the engagement components is coupled with the hub body to be axially displaceable and non-rotatable in the driving direction; another of the engagement components is provided non-rotatable at the rotor for transmitting a rotary motion from the rotor to the hub body in the engagement position of the two engagement components; and the two engagement components are configured as toothed disks and are provided with axial toothing and have an axial width that is at least the same size as half the outer radius of the axial toothing, a first one of said biasing devices associated with one of said toothed disks and a second one of said biasing devices associated with the other of said toothed disks, the biasing devices are at least partially disposed in an interior of said toothed disks, a cross-section of each of said toothed disks being L-shaped, wherein a radial leg of each of the toothed disks includes the axial toothing, and wherein said biasing devices each press against the respective radial legs of the toothed disks to urge the toothed disks toward one another in an axial direction so as to achieve a floating bearing of the toothed disks.
