The utility model has four kinds of states：Driving states, running brake state, parked state, emergency braking condition,
Illustrate individually below：
1）Driving states：Fig. 1 shows that state is driving states, and EPB hydraulic fluid port B hydraulic fluid ports enter hydraulic oil during this state,
Hydraulic coupling overcomes groups of springs（Little spring and big spring）Make a concerted effort EPB piston moved to right be pressed onto on outer end cap, parking system
Produce gap between actuator piston and running brake piston, running brake piston sidesway to the right in the presence of back-moving spring
Dynamic to be adjacent to EPB piston, EPB piston is moved to right and loosens brake(-holder) block group（Stator and moving plate）, wheel hub can be free
Rotate and realize driving.
2）Service brake state：On the basis of driving states, hydraulic oil is passed through to A hydraulic fluid ports, running brake piston is in oil
The spring force of back-moving spring side shifting to the left is overcome in the presence of pressure, brake(-holder) block group is compressed（Stator and moving plate）, brake(-holder) block group
（Moving plate and stator）The rotation that moment of friction limits wheel hub is produced in the presence of axial compressive force, braking is realized.
3）Parking braking state：Parked state is on the basis of vehicle stops（Now there is oil pressure in A hydraulic fluid ports, it is also possible to
Without oil pressure）, the oil pressure of B hydraulic fluid ports is cancelled, now parking braking piston is in groups of springs（Little spring and big spring）Spring-force driven dual
Under be moved to the left, or push the spring force of service brake piston overpowers back-moving spring and be together moved to the left, service brake piston pressure
Tight brake(-holder) block group（Stator and moving plate）, brake(-holder) block group（Moving plate and stator）Static friction torque is produced in the presence of axial compressive force
The rotation of wheel hub is prevented, parking is realized.
4）Emergency braking condition：This is a kind of state of emergency, and normal condition is prohibitted the use of, and vehicle is in motion state A hydraulic fluid port
Enter oil pressure, B hydraulic fluid ports cancel oil pressure, now service brake piston and EPB piston mode and parking braking end-state one
Sample, but act on brake(-holder) block group（Stator and moving plate）On axial force be service brake and parking braking sum, produce this braking
The maximum brake torque that device can be generated, the harm of this kind of braking is the service life for having a strong impact on stator and moving plate.
