Abstract
A vehicle auxiliary braking system is provided to accomplish a braking effect similar to engine braking inexpensively, to extend the life of the brakes, and to reduce the work cycle time in order to improve work efficiency. The system has a centrifugal sensor 20, an accelerator sensor 21, and a braking clutch engaging means that includes a braking hydraulic circuit 22. The centrifugal sensor 20 detects that the vehicle is traveling when the vehicle is moving at or above a prescribed speed. Accelerator sensor 21 detects when the depression amount of the accelerator pedal 6 is at or below a prescribed amount. The braking clutch engaging means engages the clutch that corresponds to the opposite travel direction when the vehicle is traveling at or above the prescribed speed and the accelerator depression amount is at or below the prescribed depression amount.
