US 6,352,035 B1 · Driving mechanism of a track traveling vehicle

Abstract

A track traveling vehicle having rubber tires for engaging a public road to permit the vehicle to travel thereon, and also having metal wheels capable of engaging rails associated with a track for permitting the vehicle to travel therealong. The metal wheels are supported on the chassis of the vehicle for vertical movement between a raised position wherein the rubber tires engage the road, and a lowered position wherein the metal wheels engage the rails and the rubber tires are maintained in an upwardly suspended non-engaged position. Hydraulic pumps are driven by the rubber tires when they are in the raised suspended position, and the hydraulic pumps supply hydraulic fluid to hydraulic motors to effect driving thereof. The hydraulic motors are in turn drivingly coupled to either the front or rear metal wheels to effect driving thereof when the metal wheels are engaged on the rails so that the vehicle can travel therealong.

Dependent claims

A driving mechanism of a track traveling vehicle capable of traveling on both a road and a track, comprising:

front and rear rubber road tires supported by a chassis at a lower portion thereof;
front and rear metal track wheels supported by the chassis and movable vertically relative to the chassis;
hydraulic pumps and hydraulic motors;
the track traveling vehicle traveling on the road when the track wheels are lifted and the front and rear road tires are forced to contact the road, and the track traveling vehicle traveling on the track when the front and rear track wheels are lowered to contact rails while the front and rear road tires are raised upwardly in the air;
and
the hydraulic pumps being driven by the rear road tires when they are raised upwardly in the air so as to suck and discharge hydraulic oil to the hydraulic motors, and the front or rear track wheels being driven by the hydraulic motors so that the track traveling vehicle travels on the track.

A driving mechanism of a track traveling vehicle capable of traveling on both a road and a track, comprising:

front and rear rubber road tires supported by a chassis at a lower portion thereof;
front and rear metal track wheels supported by the chassis and movable vertically relative to the chassis;
the track traveling vehicle traveling on the road when the track wheels are lifted while the front and rear road tires are forced to contact the road, and the track traveling vehicle traveling on the track when the front and rear track wheels are lowered to contact rails while the front and rear road tires are forced to be raised in the air;
and
said driving mechanism further comprising hydraulic pumps for driving use that are driven when the rear road tires are turned, hydraulic motors that are driven by hydraulic oil discharged by the hydraulic pumps for driving use, and a hydraulic motor for oil supply use that is driven when the rear road tires are turned, wherein two hydraulic circulation circuits are formed by connecting and closing both hydraulic output ends of the hydraulic pumps for driving use and the hydraulic motors;
and
wherein a hydraulic output end of the hydraulic pump for oil supply use at the discharge side communicates with the hydraulic circulation circuits, so that the two hydraulic pumps are driven at the same time when the rear road tires are turned to discharge the hydraulic oil, thereby supplying hydraulic oil that is discharged from the hydraulic pump for oil supply use to the hydraulic oil circulation circuits.
