Patent GB-1414395-A (GB)
Title: Multispeed hub
IPC: B62M11/16
Filed: 1973-02-21
Abstract: 1414395 Back pedalling brakes FICHTEL & SACHS AG 21 Feb 1973 [29 Feb 1972] 8542/73 Heading B7E [Also in Division F2] In a combined multi-speed hub and backpedal brake in which various ratios are selectable by movable coupling means, the arrangement is such that should the coupling means be in an idling condition between ratios when the pedals are operated for braking, the coupling means is automatically rendered effective to provide a transmission connection to the brake. Fig. 1 shows a three-speed planetary transmission with high ratio selected. In this condition a muff coupling member 14, which is axially movable by members 30, 31 and has a sliding, toothed drive connection with an input member or driver 1, is in engagement by a toothed clutch 9, 10, having angular lost motion, with a planet carrier 16 carrying planets 7 which mesh with a sun wheel 4 secured to a fixed spindle 5 and with an internally toothed ring gear 3, the latter transmitting drive to a hub sleeve 2 through pawls 33. Reverse rotation of the driver for braking results in reverse rotation of the planet carrier with consequent axial movement of a brake cone 34, due to a helically splined connection 36, to expand a brake member 37. To establish intermediate ratio the coupling member 14 is moved to the right to disengage the clutch 9, 10 and bring brake pawls 11 and drive pawls 12 (Fig. 9) into an internally toothed formation in a part 17 of the ring gear so that drive is transmitted through the pawls 12 to the ring gear 3, 17 and thence through the pawls 33 to the hub sleeve. Braking is now effected through the driver 1, coupling member 14, pawls 11, ring gear 3, planets 7, carrier 6, and connection 36. Motion applied to the driver in either direction when the coupling member 14 is between the high and intermediate ratio positions results in displacement of the pawls 11, 12 to the right to become effective in the part 17 of the ring gear. This displacement, which is caused by engagement of sloping parts 18 of the pawls with the end of an internally toothed extension of the planet carrier 16, is permitted by lateral clearance of a spring ring 21 in a groove 20 in the member 14. Low ratio is established by further rightward movement of the coupling member 14 to bring the pawls 11, 12 into engagement with a ring 40 to displace the ring gear whereby the pawls 33 are disengaged from the hub sleeve by a ring 42. The ring gear is then driven by the coupling member through the pawls 12, and the planet carrier drives the hub sleeve through pawls 32. Braking is effected as in the intermediate ratio.

When switch 50 is momentarily closed, coil 27 is energized, deflecting a main armature 44 to the left which impacts against the thin armature 40 and deflects the shaft 33 to the left. The armatures 40, 44 are retained in their left hand positon by means of an annular permanent magnet 31. The shaft 33 may be set to the central position shown by momentarily closing switches 51 or 52 so that armatures 44 or 45 will be deflected towards the central position, impacting against an abutment 37, fixed to shaft 33, and setting the shaft to the position shown. Similarly, switch 53 may be momentarily closed to deflect the shaft 33 to the right. The end positions may be adjusted by screwing the end poles 22, 23 into or out of the housing 20. Magnets 31, 32 may be omitted, the armatures then being held in their stable positions by means of a reduced current in the appropriate windings.

The filling may be neon with 1-10 per cent of hydrogen, less than 5 per cent and preferably 1-2 per cent being specified. As compared.with lamps filled with pure rare gas, time-lag is reduced, the resistance of the lamp is more constant, its reactance more nearly proportional to the frequency of the currents and its impedance lower, also the phase shift between current and voltage due to the lamp is proportional to the frequency in the working range, say 10,000-20,000 cycles per second. The lamp is used in the anode circuit of an amplifying valve, the circuit having a constant impedance high compared with that of the lamp. Details of the reactance &c. of the lamp in a television receiver for modulated carrier waves are given.

The carriage, Fig. 4, has wheels 14, 14<a> for travelling on transverse rails and comprises motors 15, 16 and a gear-box 17. The motor 15 is actuated by any suitable means from the compass, and rotates, through gearing 31, 30, 29, the gear-box 17, and, with it, the friction wheel 18, so that, according to the course, the chart alone, the carriage alone, or both, are moved by the rotation of the wheel 18.
