1. A guide-rail track vehicle comprising:
- a car body;
a bogie configured to support the bottom of the car body; and
dampening apparatuses that are disposed between the bogie and the car body while being separate from each other in a vehicle lateral direction,wherein the bogie includesa car body tilting mechanism that has a drive unit and is configured to tilt the car body which has a first end in the vehicle lateral direction and a second end located opposite to the first end, wherein the drive unit is configured to lift the second end with respect to the first end;
a guiding frame configured to turn while being guided by guide rails provided along a track;
a detection unit that has a displacement sensor which is fixed to a floor surface of the car body or a suspension frame attached to the car body and a link mechanism which is configured to convert a displacement of the guiding frame in a turn direction into a displacement in a direction toward the displacement sensor, wherein the displacement sensor detects the displacement in the direction converted by the link mechanism, the detection unit is configured to detect the degree of turning of the guiding frame; and
a tilt control unit that is configured to calculate a tilt angle of the car body based on a detection result from the displacement sensor, and that is configured to control a drive unit based on the tilt angle.

Abstract
This track-guided vehicle is provided with a car body, and a bogie that supports the car body from the bottom, and has a frame capable of pivoting around an axis perpendicular to a track. The bogie is provided with: a car body tilting part that tilts the car body to the left and right in the direction of travel; a detection part that detects the amount of pivot of the frame; and a tilt control part that allows the car body to be tilted by the car body tilting part on the basis of the amount of pivot detected by the detection part.

12. A car body tilt control method of a guide-rail track vehicle including a car body, a bogie configured to support the bottom of the car body, and dampening apparatuses that are disposed between the bogie and the car body while being separate from each other in a vehicle lateral direction, wherein the bogie includes:
-
a car body tilting mechanism that has a drive unit and is configured to tilt the car body which has a first end in the vehicle lateral direction and a second end located opposite to the first end, wherein the drive unit is configured to lift the second end with respect to the first end; a guiding frame configured to turn while being guided by guide rails provided along a track; a detection unit that has a displacement sensor which is fixed to a floor surface of the car body or a suspension frame attached to the car body and a link mechanism which is configured to convert a displacement of the guiding frame in a turn direction into a displacement in a direction toward the displacement sensor, wherein the displacement sensor detects the displacement in the direction converted by the link mechanism, the detection unit is configured to detect the degree of turning of the guiding frame; and a tilt control unit that is configured to calculate a tilt angle of the car body based on a detection result from the displacement sensor, and is configured to control a drive unit based on the tilt angle, the method comprising;
a detection step of detecting the degree of turning of the guiding frame; anda tilt control step of controlling the tilting of a car body based on the degree of turning of the guiding frame. - View Dependent Claims (13, 14, 15)
