PURPOSE:To improve starting performance on a sloping road and a snow-covered road and the like by increasing an axle load of a driving axle when driving force is necessary. CONSTITUTION:An axle load distributing device has an air bag means 11 to make a load act in the raising direction on a rear axle 34 by being supported with a frame, an air supply valve 13 arranged in air pressure piping 12 to connect the air bag means 11 to an air pressure source and a pressure damper 14 connected to the air pressure piping 12 between the air bag means 11 and the air supply valve 13, and has an air exhaust valve 15 connected to the air pressure piping 12 between the air supply valve 13 and the pressure damper 14 and a controller 16 to supply compressed air to the air bag means 11 by controlling so as to open and close the air supply valve 13 and the air exhaust valve 15 when driving force is necessary while inputting and processing information obtained by a transmission shift position sensor 17, a vehicle speed sensor 18, a load sensor 19 and a pressure sensor 20. |
