Definitions

  • V-belt to transfer power from one pulley to another pulley.
  • the drive ratios are varied by the flanges of one pulley being moved closer together with a corresponding separation of the flanges of the other pulley.
  • Such a system relies on friction between the belt and the pulleys and hence is only capable of transmitting relatively low power.
  • the transmission system is used on a relatively low powered vehicle in this case a scooter.
  • Figure 4 shows the transmission system of figure 3 set at a different drive ratio
  • Figure 5 shows a plan view of figure 4
  • gears 80 IB and 803B are connected via an intermediate gear, namely bevel gear 802B, bevel gears 80 IB and 803B will always rotate in an opposite direction.
  • rack 832B is being lifted by the swash plate 803 (i.e. rack 832B is coming towards the viewer when considering figure 23)
  • the pinion 834B and bevel gear 80 IB will both be rotating in an anti-clockwise direction when viewed in the direction of arrow F.
  • This anti-clockwise rotation will cause the pinion sprag arrangement 835B to engage and drive shaft 818' in an anticlockwise direction.
  • the bevel gear 803B will be rotating in an clockwise direction when viewed in the direction of arrow F and the bevel gear sprag 804B will be disengaged and freewheeling.
  • Figures 22 and 23 show a transmission system 910.
  • a single input in the form of an input shaft 912 having an axis of rotation 912' drives swash plate 930.
  • Swash plate 930 is pivoted relative to input shaft 912 at pivot 964. Pivot 964 allows the swash plate to vary the swash plate angle but ensures that both the input shaft 912 and swash plate 930 rotate at the same speed about axis 912'.
  • the swash plate 930 is a two piece swash plate 930A and 930B.
  • Piece 930B is in the form of a flange and is mounted on bearings 994 such that when part 930A rotates with shaft 912 about axis 912', part 930B does not rotate about axis 912'.
