Summary: | PURPOSE:To suppress idling (accelerative slip) of a wheel by opening No.1 set of opening/closing valves, opening No.2, No.3 sets of valves in connection to the wheel brake, when accelerative slip is sensed, and thereupon driving a pumping means. CONSTITUTION:An accelerative slip sensing means senses the accelerative slip of a wheel on the basis of the revolving speed of the wheel given by speed sensing means 101-104. When for ex. the accelerative slip of the front right wheel Fr is sensed, an accelerative slip braking pressure control means opens No.1 set of opening/closing valve 117 in connection with a wheel brake 105, closes No.2 set of opening/closing valve 123, and opens No.3 valve means 116, so as to drive a pumping means 119, and a high pressure is applied to the wheel brake 105 to suppress idling. Accordingly a front wheel differential device 109 distributes the power from a center differential device 110 also to the front left wheel FL so that the two wheels are well balanced, the center differential device 110 distributes the power of a prime mover also to a rear wheel differential device 111 while the loads on the front wheels are maintained. Thereby accelerative slip and braking slip are suppressed on individual wheels. |
