ABSTRACT:
A linear-type shuttle has an air pad 4 that blows air toward a track 5, a chassis 2 that floats above the track 5 due to the air pad 4, a primary side 6a of a linear motor that is installed to be vertically movable on the chassis 2 and that drives the chassis horizontally together with a secondary side 6b on the track 5, a brake skid 11 disposed on the chassis 2 that makes friction contact with the track 5 when the chassis 2 is not floating above the track 5, an operating lever 17 pivotally mounted to the chassis 2 and having one end connected to the primary side 6a, a spring 23 that always forces the primary side 6a upward away from the secondary side 6b via the lever 17, and an electromagnet 20 that moves the primary side 6a downward via the lever 17 against the force of the spring 23 to a predetermined position in relation to the secondary side 6b, such that, when the car 1 is floating, the gap 60 between the primary side 6a and the secondary side 6b of a linear motor is as narrow as possible so that the linear motor will be driven efficiently.
