Ratchet pawls (220, 222) with selective bias mechanism allow for rotation in a selected direction.

An interior wheel of each ratchet mechanism rotates with the sleeve (80), an exterior wheel (61,71) of each ratchet mechanism drives corresponding generator to generate.

The rod partially protrudes adjacent the ratchet wrench wheel.

The ratchet wheel is disposed between the two toothed plates and engaged with teeth and detents on the ratchet wheel.

Each ramped surface (48) includes a convex surface portion (50) which engages the struts (18) during clutch overrun so as to urge the struts (18) into the non-coupling position.

Ratchet pawls (220, 222) with selective bias mechanism allow for rotation in a selected direction.

The pawls are shaped to permit the bicycle to coast or freewheel.

The pawl and the pawl seat comprise at least two pawls and two pawl seats divided in the axial direction, respectively, and a gap exists between the pawl seats in the axial direction.

A ratchet screwdriver having an handle (10) and two pivotal pawls (26, 27) and a selector (51) rotatable relative to the handle for actuation of the pawls relative to a gear (18).

The apparatus comprises two toothed plates (51), a ratchet wheel (55), a first bobbin (58) and a second bobbin (56).

A cap (26) that is rotatable relative to the handle and that has a web for pivoting the pawls out of engagement with the gear is also provided.

Two offset pawls mounted on the bar transfer the energy to the winding wheel.

Two blocks at the ends of the rotatable piece, as the rotatable piece turns, intermittently press some ratchets inside the gravity wheel to turn the gravity wheel as well.

The rails of the first assembly include ratchet teeth, and the rail receiving platform of the second assembly includes pawls.

As a result, the interaction between the pawls and the wheel is now virtually wear-and-tear-free,” says Gäumann.
