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.
