    Provided on the supporting flange (2) is a detent star wheel (3) which is provided with recesses (12). Connected to the supporting flange (2) is a driving disc (4) with pawls (5) recessed into cut-outs (16). The rotary motion of the driving disc (4) pushes one of the pawls (5) as far as is permitted by the cut-outs (16) accommodating the pawls (5) in the driving disc. Depending on the direction of the rotary motion, one pawl (5) is pushed back into the driving disc (4) and remains inoperative, while the other pawl (5) performs an operative function. The freewheel is of uncomplicated construction and simple to manufacture and use. <IMAGE>

    专利说明:

    This invention relates to double acting freewheels with a ratchet stop for positioning on a drive shaft of a mechanical system, preferably in children's vehicles. Various types of freewheel systems or freewheel brakes with a ratchet stop are known, according to the principle of which the ratchet stops 1 are located on the drive shaft, which cause braking only in one direction. The disadvantages of these systems appear especially if they turn against the direction of rotation of the drive, as undesirable braking is then caused, then the next backward movement is prevented. To prevent unwanted braking, various additional switching elements and functional parts are used which are impractical in handling and workable only with manual control. So, for example, use the cams of a slipping clutch of a manual-clutch coupling that slides into the cam casing and prevents unwanted braking. This principle of operation is impractical since automatic shutdown does not occur and additional work is required. It is known brake device dL light motorcycles, having a brake lever, which is connected to the outer wheel, which has on its inner side a gear rim of the ratchet. It covers the inner wheel with two locking paws arranged in the recesses, which are pressed against the locking tooth with a corresponding spring. It is also known a braking device — a free-wheeling brake with dogs, placed on a drive shaft in which braking is not caused when rotating backward. This is achieved in that the bicycle wheel drive wheel can only rotate when the drive shaft rotates. There is no free wheeling when the bike moves on while the pedals are in a resting state. The known braking devices do not have a simplified free-wheeling system, which is suitable for children's vehicles. 32 The purpose of the invention is to develop a simple double acting freewheeling mechanism, preferably for three or four wheeled children's vehicles. This goal is achieved by the fact that the coupling, containing the drive shaft with ratchet stop, is provided with a flange rigidly connected to the drive and supporting flange, on which a free-wheeling system consisting of a locking sprocket, a driving disk with oppositely arranged dogs, spring-loaded pressure springs is mounted. brake disc with switching springs placed in it with a preload, with cams entering the recesses of the drive disc, while one of the dogs is blocked by a switch cam th spring and off. 8 three- and four-wheeled children's vehicles use two systems of ratchet dogs with opposite rotation. Depending on the direction of rotation of the drive, the ratchet pliers system is locked or released, and the locked system is inactive, and the released one begins to operate. The supporting flange, the locking sprocket, the remote disc are interconnected by rivets. FIG. 1 shows a dual action freewheel, slit; in fig. 2 is a depiction of the function of lock dogs with opposite rotation of the double-acting one-way clutch. The coupling includes a flange 1, rigidly connected to the drive shaft. On the 3toM flange, the support flange 2 is fixed as a support for the entire free-wheeling system. A retaining sprocket 3 is located on the support flange 2, and also a drive disk C with paws 5 and pressure springs 6 placed there. Next to the retaining sprocket 3 there is a remote disk 7, which serves to guide the distance of the brake disk 8 switching springs 9. Switching springs 9 are pre-tensioned and lie in the brake suit 8, and their cams are included in the corresponding recesses of the drive disc i. The Bcfi system is held together by rivets 10 by riveting the support flange 2, locking sprocket 3, remote disc 7 and cover plate 11. The brake disc 8 is held on the stationary part of the mechanical system and does not move. As the drive disk k is rotated, one of the two dogs 5 pushes towards. as many cams of switching springs 9 as allowable for notches in the drive disk 4. As a result, depending on the rotation, one of the dogs 5 is pressed back into the drive disk k and remains dormant, while the other dog 5 performs the function of free running or power transmission . During the next rotation of the drive disk, the switching springs 9 are gripped and slid in the brake disk 8, while with free running the position of the switching springs 9 is fixed by the brake disk 8. It is recognized as an invention according to the results of the examination carried out by the Office for the Invention of the German Democratic Republic.
