<p>An automatic brake system consists of a choke valve onto the brake oil tube, relays(14,19), pressure switches(5,22), an incline switch(9), and a limit switch(12) linked up with a clutch pedal(11). The choke valve consists of a main choke(36), a subsidiary choke(35), a plunger(31), and two solenoid valves(16,20). The limit switch(12) of the clutch is turned on at half-clutch state to release the brake at upward inclined hill without moving back.</p> |
