VEHICLE BODY ATTITUDE CONTROL DEVICE AND VEHICLE BODY ATTITUDE CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To reduce air consumption by a simplified device configuration to shorten response time in vehicle body attitude control using a pneumatic spring.SOLUTION: A vehicle body attitude control device 30 includes: the pneumatic spring 20 provided on both sides in a vehicle width direction between a vehicle body 21 and a truck frame 17; a base air reservoir 31 and an auxiliary air reservoir 32 for supplying air to the pneumatic spring 20; a control part 33 for controlling the supply and exhaust of the air with respect to the pneumatic spring 20; and a heating part 34 for heating the air supplied to the pneumatic spring 20. The heating part 34 is provided to an air supply-exhaust passage 38 connecting the control part 33 to the pneumatic spring 20.SELECTED DRAWING: Figure 2
