Abstract
A rail-supported carriage, adapted to be moved along a pair of rails spaced from one another at a predetermined distance includes at least three wheel assemblies, each including a frame; at least one wheel assembly is adapted to travel on one rail, and the remaining wheel assemblies are adapted to travel on the oppositely disposed rail. A connecting mechanism connects oppositely disposed wheel assemblies, and includes a compensating arrangement mounted on each wheel assembly for compensating any variation of distance between oppositely disposed wheel assemblies due to any curvature in the rails, each compensating arrangement includes a platform and a pin passing through the platform, and wherein the platform is movable with respect to the frame.
Claims11
A rail-supported carriage, adapted to be moved along a pair of rails spaced from one another at a predetermined distance,
- comprising in combination:
- at least three wheel assemblies, each assembly including an articulated frame, at least one wheel assembly being adapted to travel on one rail, the remaining wheel assemblies being adapted to travel on the oppositely disposed rail, and
- connecting arms interconnecting oppositely disposed wheel assemblies, and compensating means mounted between the frame of each wheel assembly and at least some of said connecting arms, establishing a sliding relation therebetween for regulating any variation of lateral distance between oppositely disposed wheel assemblies due to any curvature in said rails.
A carriage, as claimed in claim 2, further comprising
- each wheel assembly including two horizontal axles, and two wheels rotatably mounted on said axles, respectively,
- the wheels of each wheel assembly being movable with respect to each other around a respective vertical axle between a first limit position wherein the planes of the wheels are coplanary, and respectively, a second position wherein the two planes form a certain angle, the wheels being capable of assuming continuously any intermediate position,
- each wheel assembly including the supporting members each mounted on a vertical axle, and
- transmission means rigidly mounted on each supporting member, the transmission means of each wheel assembly engaging each other and being movable within a predetermined angle relative to one another to establish the maximum angle which said planes can form between each other.
The combination of a rail-supported carriage and a pair of rails spaced from one another at a predetermined distance,
- said rail-supported carriage comprising
- at least three wheel assemblies, each assembly including an articulated frame, at least one wheel assembly being adapted to travel on one rail, the remaining wheel assemblies being adapted to travel on the oppositely disposed rail, and
- connecting arms interconnecting oppositely disposed wheel assemblies, and compensating means mounted between the frame of each wheel assembly and at least some of said connecting arms, establishing a sliding relation therebetween for regulating any variation of lateral distance between oppositely disposed wheel assemblies due to any curvature in said rails.
