ABSTRACT:
A traction controlling apparatus employable in a multi-axle vehicle wherein anti-lock braking and traction controlling can be achieved with a small number of channels. The traction controlling apparatus is constructed such that air pressure control type cut valves are disposed at intermediate positions in hydraulic lines such that wheel cylinders for driving wheels and wheel cylinders for follower wheels are hydraulically communicated with each other. The hydraulic lines can be opened or closed by actuating the air pressure control type cut valves, and air pressure delivered from the traction control valve is applied tot he air pressure control type cut valves so as to allow the hydraulic paths to be closed by the air pressure control type cut valves only when the vehicle is held in the traction controlling state.
