BRAKING CIRCUIT COMPRISING A HYDRAULIC PARKING BRAKE

摘要

A braking circuit equipped with a hydraulic parking brake is provided to employ a master cylinder associated with a main service brake including a compressed fluid supply source driving a parking brake by using hydraulic pressure. A braking circuit(100) includes a main brake(102) and a parking brake(104). The main brake(102) includes a service brake or an active brake. The parking brake(104) includes a blocking unit driven by a compressed fluid and a mechanical locking unit. A compressed fluid supplying source drives the main brake(102) including a brake master cylinder(112) driven by an air compression brake booster(110). The braking circuit(100) includes a controller(144) operating the parking brake(104). The controller(144) is independent from a controller(106) for the main brake(102) or the active brake(102).
