The brake-power regulator 8 of physical construction of the present invention is as Fig. 7, it can be by casing 41, on, following carrier bar 42,43, pull bar 44, pulley 45 and track 46 are formed, upper link plate 42 is a pair of, their upper end is clamped bearing 47 both sides that are connected as a single entity with casing 41 inwalls and is articulated as one by bearing pin 48, the lower end of upper link plate 42 and a pair of upper end and pull bar 44 middle parts of carrier bar 43 down are movably connected by bearing pin 49, pull bar 44 is a horizon bar, its two ends pass outside the casing 41 and link to each other with the brake acjustment arm with the vehicle braked pedal respectively, the hinge hole 50 at pull bar 44 middle parts should be elongated hole, the lower end of a pair of down carrier bar 43 be clipped in solenoid electric valve 4 moving iron both sides and and the pulley 45 on both sides be movably connected by bearing pin 51, the both sides of corresponding two pulleys 45 are equipped with the track 46 that matches with diameter of pulley on casing 41 both sides inwalls, make pulley 45 can slide up and down in the track 46 separately.Here, solenoid electric valve 4 is made up of magnetic support 52, coil 53 and moving iron 54, and its magnetic support 52 is positioned at coil holder one end of coil 53, and moving iron 54 1 ends also are positioned at the coil holder other end, and it is hinged that moving iron 54 other ends pass the lower end of coil holder and a pair of time carrier bar 43.When glancing impact pull bar 44 in company with brake pedal reach, traction braking device 9 brakings simultaneously, the moving iron 54 of solenoid electric valve 4 is also followed pull bar 44 together and is moved up in track 46.The moving iron 54 of adhesive moves down during solenoid electric valve 4 coil electricities, and pull bar 44 returns original position again, drg 9 brake offs.Motion has just produced the effect of a little stopping so repeatedly.In the design of pull bar 44, mainly solve the seismism of pedal total travel, so that make chaufeur can adapt to use.Because the hinge hole that connects with two pairs of upper and lower carrier bars 42,43 of pull bar 44 50 is an elongated hole, hole length manys 4mm approximately than bearing pin 49 diameters.Because the gap of brake strap and brake wheel can make brake pedal produce general invalid idle travel, in pull bar 44 strokes, be about 4mm, so unnecessary control of this section idle travel, after only control strengthened treadle effort, physical construction produced the pedal stroke that elasticity changes, and chaufeur can be adapted to.
The principle of work of system of the present invention following (is example with the hydraulic structure):
Vehicle strengthens because the urgency of treadle effort is poly-when emergency braking.Make also suddenly poly-rising of braking force of wheel 24 drgs 9, thereby the deceleration/decel of vehicle is also very big, Metal Ball in the vehicle deceleration sensor 1 12 box lunches produce relatively large force of inertia at this moment, roll to the front upper place along housing 10 inwalls, contact with the binding post 11 on the housing 10, make binding post 11 and car body bonding obtain the coil that the power cathode electric current offers main relay 7.Because during emergency brake of vehicle, braking signal switch 6 has been connected, so the anodal while of storage battery E is to the coil power supply of main relay 7, then all ons of electric current at coil two ends in the main relay 7, coil produces the suction-combining force and makes its open contact closure, and the mouth of main relay 7 is the anodal electric current of outside out-put supply just.The electromagnetic valve 15 of electronic relay 3, electromagnetic control valve relay 5 and wheel speed sensors 2 has all obtained the positive source electric current at this moment.After the electromagnetic valve 15 of wheel speed sensors 2 obtained anodal electric current, just its moving iron 28 of adhesive made rotor 13 contact wheels 24 on the axle 14 or other article for rotation and rotates, and begins to enter the rolling changing condition that detects wheel 24.After electronic relay 3 obtains anodal electric current, mouth just offers solenoid electric valve 4 with power cathode electric current discountinuity, the oscillation frequency of electronic relay 3, it is the number of times of solenoid electric valve 4 power cathode switches, coil in the electromagnetic control valve relay 5, after obtaining anodal electric current, the cathodal current of coil is by 13 controls of the rotor in the wheel speed sensors 2, have only when wheel 24 slows to soon drg 9 locking wheels 24, the centnifugal force of derby 18 could be reduced to gradually by stage clip 22 and overcome in the rotor 13, extrusion metal piece 18 contacts with wire loop 20, makes the coil of electromagnetic control valve relay 5 obtain cathodal current.Coil obtains behind the electric current just with its open contact adhesive, and the mouth of relay 5 just provides anodal electric current to solenoid electric valve 4 coils, and the coil two ends of solenoid electric valve 4 obtain behind the electric current just its moving iron 39 of adhesive.When moving down plunger 30, moving iron 39 closes ball valve 32, then just turn-off the oil circuit of master brake cylinder and brake cylinder, when plunger 30 continues to move down, the inner chamber of pressure regulating valve housing 29 increases, the braking liquid of brake cylinder (being drg 9) is back in the inner chamber of housing 29, so just reduced the braking force of drg 9, so vehicle brake shoe 55 or brake clamp take-off the brake drum 56 or brake disc (see figure 5) are rolled wheel 24 again.Because the oscillation frequency of electronic relay 3 is very fast, thereby the cycle that the cathodal current of electromagnetic control valve coil 5 is opened and closed is also very short, about 10-12 time of per second (can formulate suitable frequency according to vehicle).So, when wheel 24 had been disengaged locking and is about to roll, electronic relay 3 was just closed the cathodal current of electromagnetic control valve coil 5 again, and the moving iron 39 of solenoid electric valve 4 is under the application force of brute spring 40, make plunger 30 back down ball valve 32 again, drg 9 is braked once more.
Analyze from whole design goal, all parts all are to be control brake device 9 design-calculateds.And in this anti-locking system, all electronics, electrical equipment and circuit layout all are to be control brake draught control mechanism 8 design-calculateds.In this anti-locking system, if only there is braking signal switch 6 to connect, and there is not the circuit turn-on of vehicle deceleration sensor 1, entire circuit is still obstructed.Vehicle deceleration sensor 1 is only just understood energized when spending than big retarding, and in general braking or reversing braking, all disconnect power supply, the antioverbraking device system does not devote oneself to work, and the electromagnetic valve 15 of wheel speed sensors 2 also not adhesive makes rotor 13 and wheel 24 wipe contacts.After the coil of main relay 7 obtained positive and negative electric current, electronic relay 3 just provided cathodal current to the electromagnetic control valve coil 5 of each wheel 24.The anodal electric current of each wheel 24 electromagnetic control valve coil 5 is then controlled by the wheel speed sensors 2 of each wheel 24.When a certain wheel 24 was about to be braked locking, the cathodal current of derby 18 just demand working electromagnetic control valve relay 5 coils in the rotor 13 of its wheel speed sensors 2 made the coil output cathode electric current of relay 5 to solenoid electric valve 4.The independent too control of the solenoid electric valve 4 of other wheel 24, brake-power regulator 8 and wheel speed sensors 2 car side brake 9 separately.
From whole analysis of design scheme, brake-power regulator 8 and solenoid electric valve 4 are an integral body, and their coil current is controlled by the centnifugal force inertia switch of braking signal switch 6, vehicle deceleration sensor 1, electronic relay noncontacting switch 3 and wheel speed sensors 2.And the oscillation frequency of electronic relay 3 has realized a little stopping simultaneously effect.
