VEHICLE-BODY INCLINATION DEVICE AND DOUBLE-LAYER THREE-WAY VALVE USED IN VEHICLE-BODY INCLINATION DEVICE

A carriage-body inclination device (30) has individual inclination units (112, 113) that are provided corresponding to air springs (22, 23), and a control unit (110). The individual inclination unit (112) can sufficiently execute supply or release of air to or from the air spring (22) by driving a c...

Beschreibung
Zusammenfassung:	A carriage-body inclination device (30) has individual inclination units (112, 113) that are provided corresponding to air springs (22, 23), and a control unit (110). The individual inclination unit (112) can sufficiently execute supply or release of air to or from the air spring (22) by driving a control valve (40) and a large-capacity valve (170) using a height difference value which is a difference between a height instruction value provided by the control unit (110) and a height value obtained from a link-lever mechanism (24) . The control valve (40) has a two-layer structure of a fixed sleeve (91), a control sleeve (90), and a spool (80) . The control sleeve (90) is moved and driven by the link-lever mechanism (24) and a rotation-translation conversion mechanism (44). The spool (80) is moved and driven by a spool actuator (120) according to a set height value.
