Track and bogie for suspended vehicles

A bogie (40) that supports a vehicle suspended from a track having a first (1) and a second (101) track member connected by means of ribs at regular distances along the track, comprising:

• at least one load bearing wheel (150, 250) arranged to run along an upwards facing surface (101a) of the second track member (101),
• a set of lower guide wheels including:
• a first lower guide wheel (153) arranged to run along a first lateral surface (101b) of the second track member (101) and a second lower guide wheel (152) arranged to run along a second lateral surface (101c) of the second track member (101), and
• at least one set of upper guide wheels including:
• a first upper guide wheel (151a, 151b) arranged to run along a first guide surface (16) of the first track member (1) and a second upper guide wheel (251a, 251b) arranged to run along a second guide surface (17) of the first track member (1),
• wherein the bogie (40) comprises a drive wheel arranged for running along a downwards facing running surface (15) of the first track member (1),
• wherein the bogie (40) comprises an on board switch mechanism capable of transferring torsional moments from the vehicle to an accommodating track layout at all times when negotiating switches and wherein vehicles can select paths solely through the use of the on board switch mechanism.

A transportation system comprising:

• a track comprising:
• a first track member (1) having an upper set of first and second wheel running surfaces (16, 17) facing each other in an inwards direction;
• a second track member (101) having a lower set of wheel running surfaces including:
• an upwards facing surface (101a), a first outwards directed surface (101b) on a lateral side of the second track member (101) and a second inwards directed surface (101c) on an opposite lateral side of the second track member (101), and said first track member and said second track member are spaced apart from each other and connected by means of ribs at regular distances along the track;
• first and second bogies (40) each comprising:
• at least one load bearing wheel (150, 250) arranged to run along an upwards facing surface (101a) of the second track member (101);
• a set of lower guide wheels including:
• a first lower guide wheel (153) arranged to run along a first lateral surface (101b) of the second track member (101) and a second lower guide wheel (152) arranged to run along a second lateral surface (101c) of the second track member (101);
• and,
• at least one set of upper guide wheels including:
• a first upper guide wheel (151a, 151b) arranged to run along a first guide surface (16) of the first track member (1) and a second upper guide wheel (251a, 251b) arranged to run along a second guide surface (17) of the first track member (1);
• wherein the first and second wheel running surfaces (16, 17) are inner surfaces of first and second flanges of a downwards facing U-shaped beam and wherein a web of the U-shaped beam connecting the first and second flanges has a downwards directed drive wheel running surface (15) for receiving a drive wheel (57) of a bogie (40) travelling along the track,
• wherein the bogies (40) and the track are designed such that vehicles can select paths solely through the use of an on board switch mechanism, the on board switch mechanism being able to transfer torsional moments from the vehicle to the track at all times when negotiating switches;
• and,
• a vehicle that runs along the track and having a cabin suspended from the first and second bogies.
