Description

The invention relates to mechanical engineering and can be used in de june vehicles.

The purpose of the invention is to increase reliability and simplify the design.

FIG. 1 shows the proposed coupling, cut; in fig. 2 shows section A-A in FIG. one.

The reverse freewheel includes a drive shaft 1, on which flange 2 is rigidly fixed. To the flange 2, screw 3 fastens a remote disk 4 and a washer 5. In cavities 6 of the remote disk 4 on screw 3, dogs 8 of opposite orientation are fixed, spring-loaded plate spring 9 placed inside the hollow remote disk 4. The switching spring clip 10 is located between the disk 11 mounted between the flange 2 and the brake disk 12. The distance between the ends 13 and 14 of the bracket is equal to 35

but the sum of the width of the protrusion 15 at a distance of 25 from the ends of the switching spring of the decuction disc 4 and the stroke of the staple when moving bake a clear and reliable switching of dogs 8. Switch bracket 10 has windows 16 and 17, through which dogs 8 alternately interact with ratchet teeth 18 of the disc 11. Switch bracket 10 is located in the brake disc 4 with nat -. gom

The windows 16 and 17 of the bracket are equally spaced from its ends 13 and 14. The distance from the ends of the bracket 10 to the windows is chosen from the following condition: when the end 13 of the bracket 10 interacts with the protrusion 15, then window 16, closest to that protrusion, is opposite dogs 8, and another window 17 is blocked by a bracket, with this distance L from the end 14 of the bracket to window 17 being equal to the distance from the protrusion 15 of the disk 4 to the axis of the dog 8.

The clutch works as follows.

The rotation from the drive shaft 1 is transmitted to a remote disk 4, the protrusion 15 of which interacts with one of the ends of the switching bracket 10. The switching bracket 10 rotates until the window 17 faces against the pawl 8, which is under the action of the plate pressure plate. the spring 9 is pressed and enters the window 17 of the drive disk 11, causing it to rotate.

coupling from one direction of movement to the opposite.

Claims (1)

30 claims A reverse freewheel, containing a shaft with a flange fixed on it, a washer, spaced between them in series with the drive and brake discs, a remote disc, placed concentrically with the brake disc and attached to the flange, two podrunny blued dogs opposite the drive disc are reversible orientation, interacting with ratchet teeth, and a switching spring clip with windows for dogs, covering a remote disk, characterized in that, in order to increase reliability, dis The tandem disk has recesses for dogs and a protrusion, the distance between the ends of the bracket is equal to the sum of the width of the protrusion on the remote disk and the stroke of the bracket when the dogs are switched, the ratchet teeth are made on the drive disk 50 §five lazy x on a remote drive whose width is equal to the total width of 7 drive and brake discs. 39092 When the drive shaft 1 is stopped, the drive disk 11 continues to rotate by inertia. With this, the doggie 8 oscillates as it comes in and out of the window 17 of the drive disc 1 1. When changing the direction of rotation of the drive shaft 1, the remote disc 4 together with the pawls 8 rotates with it. At this brake disc 12, due to the friction, holds the switching bracket 10 in place. Another pawl 8, which was unhealthy, rises opposite the window and under the action of the pressure spring 9 enters the window 17 of the drive disk 11, causing it to rotate together with the drive shaft 1. ten The invention allows to simplify the design of the coupling and increase the reliability of its operation. Due to the emphasis of the protrusion of the remote disk in any 35 25 of the ends of the switching spring obes-. produces a clear and reliable switch coupling from one direction of movement to the opposite. 30 claims A reverse freewheel, containing a shaft with a flange fixed on it, a washer, spaced between them in series with the drive and brake discs, a remote disc, placed concentrically with the brake disc and attached to the flange, two podrunny blued dogs opposite the drive disc are reversible orientation, interacting with ratchet teeth, and a switching spring clip with windows for dogs, covering a remote disk, characterized in that, in order to increase reliability, dis The tandem disk has recesses for dogs and a protrusion, the distance between the ends of the bracket is equal to the sum of the width of the protrusion on the remote disk and the stroke of the bracket when switching dogs, the ratchet teeth are made on the drive disk, and the dogs are set to 45 50 §five lazy x on a remote drive whose width is equal to the total width of 7 drive and brake discs.
