Title:
AXLE LOAD DISTRIBUTING DEVICE OF AIR SUSPENSION VEHICLE
Document Type and Number:
Japanese Patent JPH09109645
Kind Code:
A
Abstract:

To distribute axle load corresponding to respective traveling modes or carrying load corresponding to the will of a driver, by taking measures for controlling intake and exhaust for each axis on which an air spring is mounted on the basis of the vehicle speed and a plurality of axle loads in response to an on-signal of an axle load distributing switch.

An air tank 1 supplies air to respective pairs of front axes and rear axes square air springs 2f, 2r through an air pipe 3. The compression height of respective air springs 2f, 2r are detected by a height sensor 16. The axle load distribution of respective air springs 2f, 2r is determined by an axle load distributing sensor 5. Pressures of respective air springs 2f, 2r are respectively detected by respective pressure sensors 7, 8 as an axle load detecting means. Air pressures of respective air springs 2f, 2r are adjusted by a control unit 10 on the basis of respective detected signal. That is, respective axle independent solenoid valves 12 interposed in the air pipe 3, respective air supplying solenoid valves 14f, 14r, and respective air discharging solenoid valves 15f, 15r are respectively controlled so as to be opened and closed.
