  • Biasing means, generally designated 34 is operatively connected to the steering wheels 22a, 22b to urge the steering wheels simultaneously toward predetermined right or left positions to move the vehicle in a predetermined right or left direction.
  • the gear train 30 between the motor 32 and drive wheels 26 comprises a worm gear 36 common to the drive shaft of the motor 32 and rotatable thereby about a fore and aft axis, and a pinion gear 38 in mesh with the worm gear 36 and fixed to the rear axle 28 to drive the rear wheels 26 in response to actuation of the electric motor 32.
  • the steering wheel biasing means 34 which facilitates steering the front steering wheels 22a, 22b includes a cross brace 40 pivotally connected by identical means rigid with the steering wheels 22a, 22b. More particularly, opposite ends of the cross brace 40 has pivots at 42 for pivotal connection to yoke members 44 which are rigid with the steering wheels 22a, 22b but which are pivoted at 24 to the vehicle body or frame 20. With reference to FIGS. 3 and 7, each yoke 44 actually is pivoted on a lower cross member 46 which in turn is slidably mounted on the vehicle body or frame for limited transverse movement relative thereto.
  • a coil spring 48 is connected at its opposite ends to a pair of brackets 50 mounted on top of the yoke members 44 rigidly with the steering wheels 22a, 22b. This spring resists separation of the brackets during steering by pivotal movement of cross brace 40 and thus tends to urge the steering wheels to a neutral or straight forwardly moving direction.
  • the cross brace 40 has a rearwardly facing dihedral surface having right and left forwardly diverging surface portions 52a and 52b, respectively.
  • the motor 32 comprises a mass which is slidably mounted on top of the vehicle body or frame 20 for fore and aft movement relative to the vehicle body in the direction of arrows B (FIG. 1

  • the top of the clip is spaced from the top of the motor housing and has two cut out spring portions 60b resiliently engaging the top of the motor housing.
  • the front of the motor 32 is provided with a projection 62 which has a forwardly facing dihedral surface having rearwardly diverging right and left surface portions 64a and 64b, respectively.

  • shifting means In order to determine which of the two dihedral surface portions 52a, 52b of the cross brace 40 will be engaged by a particular one of the right and left fixed dihedral surface portions 64a, 64b of the motor, shifting means must be provided to shift the apex of the dihedral surface on the cross brace 40 right or left of the vehicle.
  • this shifting means comprises lane bordering side walls 66 along the outer edges of the outermost lanes of the tracks (described in greater detail hereinafter) and engageable with the steering wheel on the respective adjacent side of the vehicle. This engagement urges the steering wheel slightly inwardly sufficiently to insure that the particular dihedral surface portions 52a, 52b
  • the steering wheel is moved inwardly sufficiently to move the apex of the dihedral surface on the cross brace 40 to the right so that the right hand dihedral surface portion 64a of the motor will engage the left hand dihedral surface portion 52b of the cross brace 40.
  • Such engagement is shown in FIG. 6, with the motor shown in its forwardmost position urging the cross brace 40 to the right of the vehicle to bias the steering wheels 22a, 22b in the direction shown so as to steer the vehicle to the rightmost lane from the leftmost lane.
  • electrical contact (described hereinafter) is broken between the vehicle and the current conductive lane and the vehicle moves to the rightmost lane under its own inertia. In the rightmost lane, the vehicle again picks up power and proceeds forwardly.
  • the current simply is broken to the propulsion motor whereby the mass of the motor can be moved forwardly under momentum of the vehicle while the vehicle is tending to move forwardly.
  • the motor being in mesh with the rear wheels 26 by means of the gear train 30 (comprising worm gear 36 and pinion gear 38) the motor is forced forwardly, through the gear train, due to the momentum of the vehicle when the current to the motor is broken.
  • the rear wheels become the driving force to push the motor forwardly.
  • the invention contemplates the utilization of a free mass having the aforesaid engaging surfaces thereon and slidably or movably mounted on the vehicle for movement relative thereto under its own momentum as the vehicle is slowed during movement to effectively steer or otherwise control the vehicle.
  • FIG. 9 eliminates the grooves and cants the side-by-side lanes of the track from a central crest 72 downwardly toward the side walls 66 whereby the vehicle sort of leans against the side wall to urge the adjacent steering wheels inwardly. It should be pointed out that the incline of the lanes is shown'in FIG. 9 exaggerated. Actually, there is a leaning effect in the other two embodiments of FIG. 9 due to the height differential provided by grooves 70.
  • FIGS. 2, 3 and 8 show current collectors, generally designated 74, mounted on the underside of the vehicle in two of three possible positions.
  • Each current collector has an upstanding bridge portion 76 which receives forwardly protruding tab portions 78 behind the front bumper 68 of the vehicle 'to properly position the collectors under the vehicle.
  • the bridge 76 has a vertically elongated slot 80 to permit the collectors to move vertically relative to the underside of the vehicle so as not to interfere with the smooth operation of the vehicle should the tracks become somewhat uneven.

  • each track comprises a roadbed for the vehicle having side-by-side right and left current conductive lanes, generally designated 92 and 94, respectively. Except for the shallow grooves 70 the roadbed provides a substantially flush tread surface permitting the vehicles to transfer freely from one lane to the other.
  • the center of the roadbed is provided with a roughened strip 96 lengthwise therealong, the strip being fabricated of roughened material to provide better traction for the center wheels than the 'outer wheels.
  • This traction differential further facilitates holding the vehicle against the track wall to preposition the steering mechanism.
  • the roughened portion of the track may be molded directly in the track or etching or emery material, or the like, may be utilized.
  • Each lane has a plurality of contacts 98 embedded in the track for contacting the current collectors 74 to provide current from a source thereof through the contacts 98 and the current collectors to the electrically operated propulsion motors 32.
  • the track shown in FIG. 12 has six contact strips, three for each lane, two different pairs of each set of three contacts providing independent operation for a pair of vehicles, as will be described in greater detail hereinafter.

  • the only difference is in that the cars have differently disposed current collectors 74 to permit the vehicles to independently change lanes at will and/or race in the same lane.
  • each controller has a switch 108 and a rheostat 109.
  • Controller A for car A leads to contacts 1 and 3 of the left hand and right hand lanes, respectively, and controller B" for car B leads to contacts 2 and 4 of the lefthand and right hand lanes, respectively, of the track.
  • car A is powered, through current collectors 74 positioned to collect current from either of contacts 1 or 3 and the common contact 0 at the right in each lane.
  • Car B is powered by either contacts 2 or 4 and the common contact c in the lanes. This condition is shown best in FIG. 11 where line 110 leads from controller A and line 112 leads from controller B.
  • Steering of the vehicles is accomplished by either participant merely by instantly interrupting the power to the propulsion motor of his respective vehicle whereby the motor is forced forwardly to engage the steering wheel biasing means 34 to steer the vehicle toward the opposite lane.
  • the momentum of the vehicle causes it to be carried over the center roughened portion 96 of the track and the car regains power in the opposite lane whereby the worm gear pulls the motor rearwardly away from the steering wheel biasing means 34'.

  • a single secondary transformer 114 is utilized, but different polarities are associated with the two controllers A and B for cars A and B, respectively, as shown by diodes 115.
  • the controllers and cars form parallel loads on the power supply. However, these outputs are of both plus and minus polarities simultaneously with respect to the common contacts in the lanes of the track. Because of the presence of both polarities on the hot contact 116 of both lanes, each car must be wired to accept only one polarity while rejecting the other in order that they may be controlled independently.
  • each controller for the vehicle is provided with a switch 122 and a rheostat 124 and with the opposite diodes as shown in FIG. 13, the diodes providing the opposite polarity described above.
  • the invention not only contemplates the utilization of the propulsion motors 32 as the movable mass for steering the vehicle, but also contemplates a freely movable mass mounted for movement solely as a result of momentum provided by reduction in the speed of the motor.
