Abstract:     An amusement ride vehicle for travel along a trackway defined by a pair of track rails. The vehicle includes a pair of transverse frames pivotally carried by an elongated main frame, with drive wheels carried by the transverse frames in driving engagement with upper surfaces of the track rails. Up-stop or pinch wheels below the drive wheels engage under sides of the track rails. The pinch wheels are pivotally mounted to the transverse frames by strut assemblies which hold the pinch wheels in constant forcible rolling engagement with the track rails at all times. This improves the driving traction of the drive wheels and provides constant up-stop protection against separation of the vehicle from the track rails. The strut assemblies are disconnectable to enable the pinch wheels to be pivoted out of interfering relation with the track rails so that the vehicle can be lifted from the track rails for maintenance, storage or the like.

First Claim:
Show all 11 claims
I claim:     1. A vehicle adapted to travel along a trackway upon a pair of transversely spaced apart track rails each having an upper surface, a side surface and an under surface, the vehicle comprising:
  • a longitudinally oriented main frame having forward and rearward extremities;
  • a pair of transverse frames pivotally carried by the main frame adjacent the forward and rearward extremities of the main frame;
  • drive means carried by the transverse frames and including drive wheels adapted for driving engagement with the track rail upper surfaces to propel the vehicle along the trackway;
  • up-stop wheel carrier means pivotally mounted to the transverse frames and including pinch wheels located vertically opposite the drive wheels, respectively, each wheel carrier means being pivotable about a longitudinal axis between a pinch position for rolling engagement of the pinch wheels with the track rail under surfaces, and a retracted position for disengagement of the pinch wheels from the track rail under surfaces whereby the vehicle can be lifted from the track rails; and
  • strut means connected between the wheel carrier means and the transverse frames, respectively, and operative to hold the wheel carrier means in their pinch positions in forcible rolling engagement with the track rail under surfaces at all times whereby the track rails are constantly forcibly gripped and pinched between the drive wheels and the pinch wheels, and whereby the pinch wheels provide constant up-stop protection by reason of their constant forcible engagement with the track rail under surfaces, the strut means being disconnectable to enable the wheel carrier means to be pivoted to their retracted positions.
