6. the method applying energy-efficient vehicle brake apparatus described in claim 1, it is characterised in that concrete braking procedure
For:
During normal vehicle operation, sun tooth, planet tooth rotate together with brake rim with internal tooth；Front portion and brake due to sun tooth
Drum is connected by spline, when needs are braked, connects the electric current of brake synchronized solenoid, and brake synchronized pull bar overcomes pull bar
The pressure of spring, pulls brake synchronizer sleeve to move to left, and promotes brake balk ring compressing internal tooth forward taper contact surface
Combine with vehicle brake gear, connect internal tooth and power teeth；Wheel tyre, brake rim, sun tooth, planet tooth, the rotation of internal tooth are used to
Property moment, pass to output input gear through power teeth, via power transmission shaft output, reach the decelerator on vehicle and spring assembly,
Car retarder makes spring assembly deform, and the elastic force that spring produces is stayed in spring assembly；Owing to the two ends of spring assembly have
Ratchet and ratchet, one can only be entered, it is impossible to go out；One can only go out, it is impossible to enter, and therefore the pressure of car retarder work is increasingly
Greatly, the speed of car retarder declines, and the reaction force of car retarder work is applied to brake rim, and effect along path when coming
Force direction is contrary with the rotation direction of wheel, the brake force that this reaction force i.e. brakes, and the time is longer, and brake force is bigger, until
Slow down or stop；Cutting off electric current, the synchronized that brakes under the action of the spring is return, and internal tooth separates with power teeth, and vehicle does as usual and goes
Sailing or stopping, remaining energy is stayed in truck spring device；
When the electric current connecting release synchronized solenoid, release synchronized solenoid drives release synchronizer sleeve left
Moving, connecting brake rim and power teeth, the rotation of wheel is passed directly to export input gear, reaches vehicle bullet by power transmission shaft after being exported
Spring device, opens ratchet, the energy during braking of storage along path output when coming, the direction one of this active force and vehicle wheel rotation
Cause, thus promote vehicle to advance；Cutting off the electric current of release synchronized, discharging synchronized return, remaining energy stays vehicle bullet
In spring device, vehicle does as usual and travels；This release has all release and part two kinds of selection modes of release, the part staying as under
The initial brake power of secondary braking；
Vehicle is when braking, and due to inertia force reach, the brake force in automobile front-axle is strengthened, and speed is faster, increases more, and system
Power extends in time and increases, and according to the speed information of Hall wheel speed sensors perception, extends the braking time on front axle, i.e.
The brake force of automobile front-axle can be increased；
During normal traveling, owing to being compressed by security personnel's spring, the power of brake rim reaches guarantor through the effect of clutch combined block
Peace system；And when lower long slope, first give release synchronized solenoid energising, in conjunction with release synchronized, then give security system electricity
Magnetic coil is energized, and security system clutch combined block is opened by suction, leaves binding site, and at this moment tire and tire steel bushing skid, and protect
The generator rotation of peace system, the energy major part being stored in during braking in truck spring device is released；Cut off security system
The electric current of solenoid, clutch combined block return under the pressure of security personnel's spring, vehicle can normally travel.
