For the braking of the second motor 11 and two kinds of operating modes of Associated brake.In the case of non-emergent braking, and speed is higher than a certain restriction
During value, into braking mode.Turn if demand braking moment now is less than the maximum braking that the second motor 11 can be provided
Square, just it is stored in by the independent brake of the second motor 11, the regenerating braking energy of feedback in electrokinetic cell 5.If the braking of demand
Torque is more than the maximum braking torque that can be provided of the second motor 11, just by the second motor 11 and mechanical brake Associated brake,
The electrical power storage reclaimed by the second motor 11 is into electrokinetic cell 5, and another part energy is by mechanical brake in the form of heat energy
Dissipate.
