<p>PURPOSE: A positive displacement type braking device for a speed decrease and braking is provided to perform an ABS(Automatic Braking System) function without an ABS unit and be interacted with other electronic control units. CONSTITUTION: A positive displacement type braking device comprises a brake disc(10), a cylinder case, a piston driving unit, a driving motor(200), and a driving unit actuator. The brake disc comprises a disc vane(b100) and is installed in the cylinder case. The cylinder case partitions the inner space of the cylinder into plural partitions. The piston driving unit comprises a piston roller(21). The piston roller is contacted with the brake disc. The piston driving unit performs the speed decrease the braking of a vehicle. The compressed pressure is generated between the piston roller and a single disc vane. Vacuum pressure resistance is generated between the piston roller and another disc vane. The driving motor is controlled an ECU(Electronic Control Unit). The driving unit actuator drives the piston driving unit.</p> |
