CONTROLLER FOR START ASSISTING APPARATUS

摘要

PURPOSE: To improve a drive force at the start of a vehicle by providing a pneumatic spring for regulating the ground contact pressure of a drive shaft and detecting a change in the axial load by a level sensor for controlling the operation of the pneumatic spring. CONSTITUTION: A drive shaft of two rear shafts is equipped with a start assisting apparatus using a pneumatic spring 505 to increase the ground contact pressure and the traction in the start when a vehicle is started or the like. A controller 800 supplied air to the pneumatic spring 505 when an empty vehicle is stopped, and exhausts the air when the loaded vehicle is stopped or moved with the speed exceeding the set vehicle speed. Also, the air pressure can be regulated within the range of a set value to improve the durability of the pneumatic spring.
