    A dual speed bicycle hub with a planetary gear transmission and automatic gear shift operated by a centrifugal governor is additionally equipped with a manual override permitting manual speed selection while movement of the flyweights in the governor under the influence of centrifugal forces is blocked. The manual controls may hold the flyweights near or remote from the axis of hub rotation and thereby engage or disengage an overrunning clutch which connects a fast-moving transmission element to the hub shell.

    (St) MULTI-SCORES; THICK BIKE SLEEVE
    one
    The invention relates to the bicycle industry, in particular to multi-speed bicycle sleeves,
    A multi-speed bicycle hub is known, comprising an axially rotatable cam, a ratchet body, a planetary gear housed inside the body, a ratchet located between one planetary gear unit and the body, and a centrifugal switch with a shift lever located on the centrifugal counterweight having control lever l.
    The disadvantage of this design is that the switching of speeds in it occurs automatically from the speed of movement, determined by the number of revolutions of the sleeve.
    The aim of the invention is to provide the possibility of manual control.
    This goal is achieved in that the sleeve is provided with a glass mounted rotatably on the axis, an axial movement mechanism connected to the glass and an emphasis mounted rotatably about the axis of the glass and connected to the axial movement mechanism on the counterweight of the centrifugal switch least one surface interacting with the stop.

    The bushing has a housing 1, an axis 2 and a cam 3 with a ring gear 4 mounted by ball bearing 5 on axis 2. The cam 3 is equipped with 6 axle planetary gears and serves as a support for the planetary gears 7. The free ends of the axle 6 planetary gears 7 are interconnected by support ring 8. In the plan, the gears 7 on the cam 3 are engaged on one side with the sun gear 9 fixed on the axis 2 and on the other side with the gear 10 with the internal gear. The support ring and is rigidly connected by means of a gear coupling 11 to the support sleeve 12 mounted on the axis 2 rotatably and stationary in the axial direction by means of the locking ring 13. The support sleeve 13 is rigidly connected by external engagement 14 to the part 15 axially located on the axis 2, having internal tooth cut 16. In this way, the part 15 connected to the support sleeve 12 has an end portion 17 adjacent to the cylindrical part 17 in the form of a disc with radially open receiving pockets 18 on the periphery, in which x placed latches 19. Two diametrically opposed tabs 19 finds schies under the influence of the spring clamping ring 20, the end portion 17 is supported zgitselok In this embodiment mnogoskoros hydrochloric transfer sleeve provided. The latches 19 are located opposite the ratchet 21 in the sleeve housing 1, which in turn is mounted by ball bearing 22 on the cam 3 or on another rigidly connected to the axis 2 of the bearing part 23. The sleeve has an axially moved mechanism consisting of a sliding block .24 and The gland 25. The end part 17 is mounted on the bushing with the possibility of axial movement by means of the sliding block 24 through the bushing 25 and the chain of engagement of the latches 19 with the ratchet 31, as well as the rigid connection with the support bushing 12 while not collapsing. The gear wheel 10 with internal gearing is rigidly connected by a power coupling 26 with a support 27. They are located so that they can be rotated on a wa-. 28, centrifugal counterweights 29 control the distributor disk 31 provided near the center of gravity of the trunnion 30. The latter has shaped cutouts for controlling the latches 32 placed rotatably on the support 2 of the counterweights 29. The latches 32 are clamped by an annular spring element and can, with corresponding position the distributor disc 31 deflect and engage with an annular leader 33 fixed rigidly on the sleeve. The counterweights 2 are constantly under the action of return springs 34. On the part 15, an annular friction spring 35 is elastically clamped in the groove with a radially bent elastic tongue 36, which can temporarily work together with the counterweights. On the counterweight 29, the axis 37 and the -shaped At the same time, one shelf and one-shaped part are marked 38, and a U-shaped transition is marked 39. At the end of the nominal end, each counterweight 29 has another cam lug 40 running from one side in the axial direction, and its U is figurative passage extends in the circumferential direction. The counterweights 29 cover the part 15. The sleeve also has a spring 41, a cup 42 and a centrifugal switch 4 3. In FIG. Figures 1 and 2 depict the working position of the multi-speed bushing in the right end position of the mechanism, the axial movement. At the same time, the end part 17, having the possibility of axial movement along the corresponding groove by means of the sliding pad 24, is positioned so that the elastic tongue 36 of the friction spring 35 can pass through the U-shaped transition 39 and the-shaped surface 37 of the centrifugal counterweight 29. Adding the cam 3 by the support ring 8 rotates the support sleeve 12 and by virtue of the same part 15. The gear wheel 10 with internal gearing and thanks to this also the support 27 of the counterweights 29 of the centrifugal switch 43 rotates with bo its high speeds than the cam 3. The counterweights rotate with their support 27. As they rotate faster than the tongue 36, the latter passes through the junction 37 and hits the projection 40 (Fig. 2), the tongue 36 and the friction spring 35 the protrusion 40 of the more rapidly rotating centrifugal counterweight 29 is gripped. The resistance caused by the friction of the friction spring 35 relative to the cup 42 forces the counterweight 29 forcefully, so that the latter is held in the shape shown in FIG. 2 position and may deviate radially outwards. By means of the control pins 30 and the distribution disk 31, it is prevented. also the deflection of another counterweight 29. This is clearly seen in FIG.

    2. The sleeve is driven from the cam 3 through the support sleeve 12, part 15 and the latch 19 to the sleeve body 1. The conversion speed does not occur. This corresponds to the normal course. If, by moving the shoe 24 and the cable to the left, the position shown in FIG. 3, the high speed is thereby activated. As before, the counterweights 29 of the centrifugal switch 43 rotate faster than the tongue 36. However, now due to the displacement of the part 15, the shelf 38 of the U-shaped surface 37 slides in a circumferential direction relative to the tongue 36. After this, the shelf 38 hits the tongue 36, so that the last the counterweight 29 is again gripped. Again, the frictional resistance of the friction spring 35 creates a force on the counterweight 29. This force applied to the shelf 38 of the U-shaped surface 37, this time causes the deflection of the counterweight 29 to the one shown in FIG. 4 position. By means of the control trunnions 30 and the distributor disk 31, the second counter weight 29 is also deflected, at the same time being released at once and the latch 32 is able to deflect from the distributor disk. The latter are included in the annular leash 33, so that the sleeve housing .1 is now rotated with the number of revolutions of the gear wheel 10 with internal engagement, regardless of the speed of movement, the latch 19 is again advanced. In yet another switching position, the end portion 17 is axially displaced so far against the tension of the spring 41 that the tab 36 of the friction spring 35 can freely pass past the outer shelf 38 of the surface 37 of the counterweights 29. Consequently, in this position the tab does not act on the balance 29 ; so the latter are always under the action of centrifugal force. The position of the counterweights 29 of the centrifugal switch 43 depends exclusively on the number of turns of the leash. Claims of the Invention Multi-speed bicycle comprising a rotatably mounted cam, a ratchet body, a planetary gear housed inside the body, a ratchet located between one link of the planetary gear and the body, and a centrifugal switch with a shift lever located on the centrifugal counterweight having 1 control lever, so that, in order to allow manual control, it is provided with a cup mounted rotatably on it. the axial movement mechanism connected to the glass and the stop mounted rotatably about the axis of the glass and connected to the axial movement mechanism, and at least one surface interacting with the stop is mounted on the counterweight of the centrifugal switch.
