The specific braking procedure of the car emergency complemental brake system is exemplified below.
Electronic control unit 1 gathers wheel speed sensor and brake pedal displacement transducer signal, carries out at signal
Reason, does not have brake pedal when detecting driver, or when driver's brake pedal and wheel speed reduction, Electronic Control
Unit 1 sends cut-offing instruction, and magnechuck 13 is powered off, and electromagnetic attraction disappears, and frictional disk 11 is not contacted with brake pad 10.Driving tooth
Wheel 3 drives main driven gear 5 and secondary driven gear 7 to dally, and main driven gear 5 drives the frictional disk 11 and baffle plate 14 being coaxial therewith
Idle running.Secondary driven gear 7 drives the follower gear 8 being coaxial therewith to dally, because counter gear 9 is engaged with follower gear 8, and with
The empty set of main shaft 4, follower gear 8 drives counter gear 9 to dally.Whole device is in idling conditions, without braking, gear idle running
The energy of consumption can be ignored, and not increase the resistance of automobile normal running.
When detecting driver's brake pedal and four vehicle wheel rotational speeds are constant, electronic control unit 1 sends energization
Instruction, magnechuck 13 produces electromagnetic attraction, and frictional disk 11 is contacted with brake pad 10.Driving gear 3 drives the He of main driven gear 5
Secondary driven gear 7 is rotated, and rotation direction and driving gear 3 is in opposite direction.Main driven gear 5 drives the friction being coaxial therewith
Disk 11 and baffle plate 14 rotate in same direction.Secondary driven gear 7 drives the follower gear 8 being coaxial therewith to rotate in same direction, due to counter gear 9
Engaged with follower gear 8, and with the empty set of main shaft 4, therefore the rotation direction and the rotation direction phase of frictional disk 11 of counter gear 9
Instead.Frictional disk 11 has carried out circumferentially fixed, therefore spline of the frictional disk 11 by the electromagnetic attracting force of magnechuck 13 along main shaft 4
Axial movement, frictional disk 11 is contacted with brake pad 10, is relatively rotated in the opposite direction, is carried out using reverse speed difference auxiliary between the two
The kinetic energy in friction catch, vehicle traveling process is helped to be converted into the heat for the generation that rubbed between frictional disk 11 and brake pad 10, vapour
Vehicle speed slows down.The heat that the friction catch is produced directly is blown to four winds, perfect heat-dissipating.Between frictional disk 11 and brake pad 10
Contact normal pressure determined by the electromagnetic attraction size of magnechuck 13.When frictional disk 11 is touched with the rigid connection of brake pad 10, speed difference
Greatly, it is to avoid application load suddenly, now electrical current is smaller, and the suction of magnechuck 13 is small, i.e. frictional disk 11 and brake pad 10
Normal pressure it is small, braking friction is small, plays and slowly applies loaded effect, ensure high speed braking procedure it is steady.Certain time
Afterwards, the electrical current of magnechuck 13 is increased, the suction increase of magnechuck 13, the i.e. normal pressure of frictional disk 11 and brake pad 10 increases
Greatly, braking friction increases, and plays the effect of fast braking.
