Description
The utility model belongs to a kind of automotive anti-lock braking device, and this device is installed in the automobile brake hydraulic pipe road, with prevent automotive wheel in braking procedure by locking.
The various automobiles of automotive anti-lock braking device are not installed, when emergency braking all deviation phenomenon can appear in various degree, its reason be wheel in braking procedure prematurely by locking, yet under effect of inertia, tire and road surface have produced cliding friction, again since the both sides wheel poor on the friction coefficient on the time of locking and between road surface and each tire, different from making vehicle lateral rotation and sideslip occur, this out-of-control phenomenon is particularly outstanding for the higher vehicle of center of gravity.Seriously can cause slide-out, deviation phenomenon is irregular again to be followed, and very easily causes pursuit-type vehicle because of the collision accident of being too late to dodge.
The purpose of this utility model provides a kind of automotive anti-lock braking device, to overcome wheel that automobile occurs at glancing impact by locking phenomenon.
Technical solution of the present utility model is: a kind of automotive anti-lock braking device, it comprises pedal 1, hydraulic actuating cylinder 6 brake clamps 15, connect hydraulic actuating cylinder 6 and brake clamp 15 hydraulic tubing 7,14, with the brake disc 16 of brake clamp 15 couplings, it is characterized in that: be connected to electromagnetic valve in the middle of the described hydraulic tubing 7,14, electromagnetic valve joins with electrical generator 17 or storage battery 18 respectively, and the rotor wheel of electrical generator 17 and brake disc 16 join.
Described electromagnetic valve is by the valve body 13,19 that joins with pipeline 7,14, the electromagnet 12 that is positioned at the spool 8, spring 11 of valve body 13, joins with valve body 13, the spool 10 of valve body 19, the rope 9 that is connected spool 8 and 10 are formed, also be connected between valve body 19 and the hydraulic actuating cylinder 6 and hold liquid case 20, and be provided with a check valve 25 at least.
The utility model compared with prior art, because the electromagnetic valve of controlling by the electrical generator that is installed in wheel middle part or storage battery is installed in brake hydraulic line, this electromagnetic valve braking force that the scalable brake clamp is produced in braking procedure, therefore the utility model has overcome wheel in the car brakeing process by locking phenomenon, the manipulative capability and the safety of vehicle have been improved, avoided vehicle in the glancing impact deviation phenomenon effectively, can keep tire and road surface all the time near maximum static friction force, also has good deceleration and stopping performance, shorten stopping distance, simple in structure, cost is low.
Below in conjunction with the drawings and the specific embodiments the utility model is further described:
Fig. 1 is the structural representation of the utility model specific embodiment.
As shown in Figure 1: in hydraulic tubing 7,14, be serially connected with valve body 13.Valve body 13, inner chamber is provided with can axially movable spool 8 and spring 11, valve body 13 bottoms fixedly are connected to electromagnet 12, when electromagnet 12 energized, spool 8 is attracted, and spring 11 is compressed simultaneously, hydraulic tubing 7,14 connections this moment, when electromagnet 12 outage, spool 8 is displaced downwardly to upper in the effect of spring 11, this moment hydraulic tubing 7 with 14 disconnections.In the middle of pipeline 7,14, also be provided with valve body 19, also be provided with spool 10 in the valve body 19, adopt rope 9 that spool 8 is connected with 10, promptly can spur spool 10 activity that makes progress when spool 8 moves to when upper rope 9.One end and the valve body 19 of pipeline 24 join, the other end with hold liquid case 20 and join, and be provided with check valve 25, hold liquid case 20 and join, and be provided with check valve 26 with hydraulic actuating cylinder 6.Above-described valve body 13, spool 8, spring 11, electromagnet 12 and valve body 19 and spool 10, also can adopt the 2/2-way solenoid directional control valve (
) replace.Be fixed with dynamo generator 17 at the wheel center place, the rotor wheel of electrical generator 17 is captiveed joint with brake disc 16, and both also can adopt other type of drive, drives electrical generator 17 generatings when rotating with the assurance brake disc.The binding post of electrical generator 17 is by lead and contact 2,4,22 and electromagnet 12 join (referring to accompanying drawing).The folding of bidirectional switch 3 difference control contacts 4,22 and contact 5,23, the opening and closing of contact 2 are by pedal 1 control.By contact 5,23 and lead storage battery 18 and electromagnet 12 are connected into the loop.
Its working process is: when high vehicle speeds, press bidirectional switch 3, make contact 4,22 closures, because in the driving process, do not depress pedal 1, contact 2 is in opening, contact 5, also be in opening 23 this moments, spool 8 is in upper under the effect of spring 11, pipeline 7 and 14 places and off state, when the need braking brake, depress pedal 1, make contact 2 closures, electrical generator 17 is connected with electromagnet 12, electromagnet 12 attracts spool 8, spring 11 is compressed, and this moment is owing to pipeline 14 and 24 is cut off in the deadweight of spool 10, and pipeline 7 and 14 is connected, because the effect of pedal 1 moves to right piston 21, high pressure oil drives brake clamp 15 work and stops brake disc 16 to rotate, and reaches the purpose of drag, when the speed of a motor vehicle is reduced to electric energy deficiency that electrical generator 17 produced so that electromagnet 12 when attracting spools 8, be that wheel is when desiring by locking, move on the spool 8 and by pipeline 7 and 14, drive upwards activity of spool 10 simultaneously, make pipeline 14,24 connect, high pressure oil in the pipeline 14 by the road 24, check valve 25 enters and holds liquid case 20, brake clamp 15 loosens, and wheel begins again to rotate, so repeatedly circulation, wheel is in desires, again not by the rolling condition of locking by locking.
Even vehicle depresses pedal 1 when low speed driving, because the electric energy that electrical generator 17 is produced can not make electromagnet 12 reach mode of operation, this moment, brake hydraulic line remained open circuited, did not have brake action, in order to address this problem, can adopt the way of connecting storage battery 18 to solve, as shown in the figure: on put forward bidirectional switch 3, make contact 5,23 closures, under the effect of storage battery 18, electromagnet 12 work attract spool 8, make pipeline 7 and 14 connect the purpose that reaches braking.
The utility model is not only limited to the above embodiment, and any possible embodiment all belongs to the utility model basic thought.
