Description

The present invention relates to a ratchet mechanism for the purpose of transmitting movement in the same direction by using dogs fastened to a part connected with either the driven part or the leading part, and the dogs freely rotate around their axes and are located between two concentric gears. crowns with inclined teeth that are integral with the Other part, which is in turn associated with either the drive part or the driven part.

In FIG. 1 shows the ratchet wheel of the proposed mechanism; FIG. 2-part of the mechanism, bearing the dogs, designed to work with the ratchet wheel; FIG. 3-modification of the ratchet; FIG. 4 - a modified device dogs

The ratcheting mechanism shown in FIG. 1 and 2 consists of a pedal wheel of a bicycle mounted on an axis with an opening 8 of a ratchet wheel 1, provided with teeth 7 on the outside, and inside with two gear rims 3 and 4, and part 2 of the mechanism carrying the pawl, and associated with a hole 9, for example, with a hub bike wheels. Detail 2 mechanism

(Fig. 2) is equipped with axles 6, on which dogs 5 are loosely mounted,

; fishtail shaped. Temple The second wheel of the mechanism 1 (Fig. 1}

I equipped with two toothed rims

3 and 4, the teeth of which are inclined

in opposite directions and arranged so that the teeth

; inner rim 3 are pro. tiv cavities external crown 4.

When assembling the mechanism (Figs. 1 and 2), the I parts are opposed to each other so that the pawls 5 are between the gear vents 3 and 4 (the dotted line in Fig. 1). When j rotates the ratchet wheel 1 (Fig. 1), I connected with the leading device, in the direction of the arrow, the driven part 2 I (Fig. 2) will be carried away, and the dogs 5 will engage with the gear crown 3 or the gear veins; com 4, and vice versa, when part 2 i rotates opposite the arrow, the tanks will push up and down, rotate around their axes and slides along the inclined surfaces of the teeth, without interfering with part 2.: Modified device furs; nizhm (Fig. 3 and 4) is equipped with an external gear crown 4 and the inner
