Definitions

  • the present invention is directed to a gyroscopic de-
  • the device comprises a gyroscopic disc mounted on a swivelling support.
  • the disc rotates in an oscillating plane according to the orientation of the support and according to the tilt of the vehicle. This plane is substantially parallel with the one passing through the line of the contact points of the vehicle with the travelling surface and the center of gravity of the vehicle.
  • the disc rotates even after the vehicle has stopped. It is rotated either by a wheel actuated by the movement of rolling surface of the vehicle either by an independent motor either by the propulsion motor. After the vehicle has stopped, the disc rotates through its own inertia, due to a free wheel mounted on the transmission.
  • the stability device and the direction system may include a control system.
  • the present invention is directed to cycles having two wheels which are motorized or not. More particularly, the invention is directed to a device which enables to increase the stability of a cycle whether the latter is in movement or is stopped temporarily. Such a device will also permit to regularize the energy which is necessary to operate the cycle.
  • the device of the present invention enables to improve the stability of two-wheel bicycles when'they are stopped as well as when they are moving slowly or rapidly, and to regularize the driving force of the'cycle, the latter resulting from the pedals or from a motor in the case of a motor cycle.
  • This second result is obtained by means of a single stabilizing gyroscopic wheel which stores a certain amount of energy when driving down hill and partially restores the same when going uphill.
  • the driving mechanism of the gyroscopic wheel which consists of a pawl system (or freely rotatable wheel) operates only when in rotation and comprises belts and pulleys which are arranged especially for slipping (flexible clutch) and defines a way of restoring to the front wheel the energy which has been stored in the gyroscopic wheel, when driving at high speed.
  • the belts can easily be replaced without dismantling the wheel.
  • this device including belts and planet pulleys produces two effects: the first one contributing to better overcome the supplementary inertia of the gyroscopic wheel when starting the vehicle; the second effect enabling to better recuperate the energy which hasbeen stored by the said gyroscopic wheel (for example when going downhill) when the vehicle slows down (for example when going uphill).
  • FIG. 1 is a partial half section through the axis of the wheel provided with a stabilizing device.
  • FIG. 2 is a schematic view on the right-hand side of the wheel.
  • FIG. 3 is a schematic view on the right-hand side according of thecross-section A A shown in FIG. 1 and illustrating the essential arrangement inside the wheel.
  • FIG. 4 is a schematic decomposition in the plane x x z z of the main parasitical, and precession couples accord-ing to the embodiment described.
  • FIG. 5 is a decomposition of the re-establishment forces of the tilt in the case of FIG. 4.
  • FIG. 6 is a schematic representation of the couples in the case wherein the disc is spaced from the vertical plane of equilibrium and in parallel relationship.
  • FIG. 7 is a decomposition of the efforts in the plane x x, z z.
  • FIG. 8 is a schematic representation showing the couples in the case wherein the axis of the disc is parallel to the axis y y, that is, practically horizontal.
  • FIG. 9 is a schematic representation showing the couples in the case wherein the axis of the disc is practically vertical.
  • the device essentially comprises a disc 1, which may be perforated, approximately in the longitudinal median plane of the wheel. It is rigidly secure to a tube used as a bearing for a ball bearing Sand 4, rotating about an axle of the wheel 5. The latter is freely mounted on the ball bearings 6 and 7 on the axles formed by a fixed rod 8, rigidly supported by the fork 9 or support of the direction. At one end of the tube 2, isfixed a pulley 10 having a double throat, which directly drives the disc 1.
  • the bearing 12 of the axle l3 enables the latter to freely rotate.
  • the said axle l3 combines and synchronizes the two pulleys l4 and 15 having different diameters, the said pulleys operating in a planetary arrangement.
  • the pulley l5 drives, the pulley 10 through a set of belts conveniently crossed.
  • the pulley I4 is equally driven by belts through the pulley 16 which is coaxial with the wheel of the cycle and the disc, that is, with the axis x x.
  • the said pulley 16 is mounted on the axle 8 to a driving wheel in a single direction of the free wheel type 17.
  • the inner part 18 of the latter is therefore fixed.
  • the pulley l6 freely rotates in aclockwise direction for an observer seeing the vehicle passing from the right to the left, or what is identical in the direction indicated by the arrow 19 in FIG. 2.
  • the said pulley 16 cannot rotate in the reverse direction of the arrow/For a purpose of equilibrium, there may be two trains of pulleys l4 and 15 which are diametrically opposed on the disc 11.
  • the frictions in the free wheel 17 have also a tendency to slow down the rotation of the axle l3 and have the same effects. It is obvious that all these frictions appear when the gyroscopic wheel 1 starts to accelerate, for example going downhill; however, the energy is then supplied by the vehicle itself which is dragged down by the slope, said vehicle not requiring the same kind of braking by the brake shoes (energy completely lost).
  • the frictions caused by the rotations of the pulleys l4 and about their own axes can be measured by means of rings mounted on the bearings 12 or even on the free pawl wheel 17.
  • belts 24 and 25 can easily be dismantled and replaced without dismantling the front wheel. It is only sufficient to remove them from over their respective pulleys in order to recuperate them.
  • the planet pulleys l4 and 15 are diametrically opposed in order that the efforts be well distributed around the axis of the wheel of the cycle.
  • the two belts 24 and 25 are mounted symmetrically with respect to the diameter extending through the axes l3.
  • the device for recuperating the energy of the gyroscopic wheel which rotates by its own inertia tends to move the cycle forward. This has no importance since it is only sufficient to keep the brake tight as long as the gyroscopic wheel rotates, said gyroscopic wheel enabling to improve the stability when the vehicle has stopped.
  • FIG. 4 schematically represents a disc 1 rotating in the direction of the arrow around its axis x x. It is illustrated in the plane 26 passing through its center 0 and the lines of contact points y y' of the wheels on the ground.
  • the fork that is, the support, adapted to swivel by the steering handle of the rotation axis x x of the said disc 1, pivots around the axis z z.
  • This movement which is produced in the direction of the arrow 27 drives a couple around the axis y y', and this in the direction of the arrow 27 (precession), according to the known laws of the gyroscope.
  • This couple according to the arrow 28 produces around the resting points of the vehicle, constituted by the axis y y, a couple according to the direction 29, through the fork 9 and the frame of the cycle. While decomposing the forces which are then created, on FIG. 5, one can see that a composing force appears in 30 according to the axis x x which tends to tilt the vehicle towards the right (FIG. 5).
  • FIG. 7 shows a decomposition of the forces in the plane formed by z z and x x, that is, perpendicular to the axis y y.
  • FIG. 9 shows the relationship between the couples. But in this case, 2 2' becomes perpendicular to the plane 0, y y. It results that in upward or downward slopes, a parasitical oscillating movement, around the axis 2 z produces a parasitical precession couple around Y Y which tends to produce an unfortunate tilt of the vehicle, while the driver would prefer to follow a straight line. This observation leads to some difficulties which may result in the impossibility of driving the vehicle at a fast speed.
  • a gyroscopic device for stabilizing and regularising the propelling energy in a two-wheel cycle said device being mounted on said two-wheel cycle and comprising two trains of planet groove pulleys, a disc solid with the front wheel of the two-wheel cycle, said two trains of planet groove pulleys pivotally mounted on said disc, said trains of pulleys both beingparallel to the front wheel of the cycle and mounted equidistant to the center of said front wheel of said cycle, a bearing mounted on said disc each of said trains of pulleys pivoting on said bearing, a shaft solid with said bearing each of said trains of pulleys being mounted on said shaft and comprising a double groove pulley which is connected by means of belts with a drum which is solid with a gyroscopic wheel, said gyroscopic wheel freely rotatable over the axle of the front wheel of. the cycle, and a simple groove pulley which is connected by means of a belt to
  • each of the belts is mounted with a predetermined tension and a low winding angle of about around the said drum in order that it can slip when starting said cycle.
  • bearing carrying the axle of each of the planet pulleys comprises a friction controlled ring adapted to transmit to the wheel of the cycle by means of the pulleys and belts, the energy which has been stored by the gyro scopic wheel of the vehicle.
