The utility model relates to an anti-locking device for the hydraulic braking of an automotive vehicle, which is connected to the hydraulic braking system of the automotive vehicle. The utility model is characterized in that the utility model is provided with two cavities, wherein, a sealing piston is arranged in a piston cavity which is provided with an oil inlet interface; the front part of the piston is a sealing end part which is connected with a moving rod whose end part pushes a return spring; the sealing end part the piston cavity is provided with a piston closing opening which is connected with an outer oil cavity which is provided with an oil outlet interface via a channel. Thus, the utility model has the advantages that the utility model has simple structure, easy operation, low cost, safety easy installation, etc., and can effectively avoid all traffic accidents due to emergency brake.
Description
The utility model relates to a kind of being applied in the brake of motor-driven vehicle device, be used to prevent the device of car brakeing locking.
At present, experienced automobile driver often can not be when emergency braking when driving the coventional type self-propelled vehicle, and a pin is floored, otherwise will take place that bearing circle is out of control, accidents such as sideslip and whipping take place, and cause the malignant event of car crash easily.This is because at the hydraulic pressure coventional type automobile below 3.5 tons, its brake structure mainly includes brake pedal, oil pressure master cylinder and piston, the adjacent shoe plate of putting with wheel hub etc., when chaufeur is taked emergency braking, step on brake pedal, oil pressure master cylinder output oil pressure, pressure are added to each oil pressure wheel cylinder, wheelcylinder piston spreading shoe plate, and shoe plate and wheel hub friction are stopped automobile immediately, because the inertia forward of automobile, automobile can be beaten side, whipping, and bearing circle is uncontrollable at once.Also can when stepping on brake, behind the shoe plate spreading, wheel hub and shoe plate be checked immediately in addition, can make the automobile generation beat accidents such as side, whipping, bearing circle be out of control equally because of wheel hub circle or not slight concavo-convex.
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provides a kind of being installed in to be used to prevent the hydraulic braking locking in the motor-rehicle braking system, to avoid bearing circle automotive hydraulic brake anti-lock device out of control.
The purpose of this utility model is finished by following technical solution, it is connected in the hydraulic braking system for automobile, mainly contain a piston cavity of bringing oily interface into, be mounted with the packed-piston of a Tape movement bar in it, shifting bar stretches out that roof pressure has a pull back spring outside piston cavity, have a piston to remain silent in the piston cavity, it is communicated in another outer oil cavity body that has oil out port.
Shifting bar described in the utility model stretches out, passes outer oil cavity body by the interface channel that is communicated with outer oil cavity body from the piston closed end, the hermetic terminal of piston is the frustum shape, and has hermetic terminal that piston remains silent on the piston cavity also for the frustum shape that matches is with it arranged.
The utility model in described piston cavity, the other end of piston is provided with the spring of roof pressure, the oil-feed interface is arranged on the chamber wall of piston oil pocket of piston shift position.
Description of drawings is as follows:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the utility model is connected in the structural representation in the brake system
To be described in detail the utility model by accompanying drawing below: Fig. 1, the utility model mainly contain a piston cavity 1, are mounted with packed-piston 2 in it, and the cavity wall that is positioned at packed-piston 2 positions is provided with oil-feed interface 3.Also be mounted with a spring 4 in the cavity 1 and pressing the rear portion of packed-piston 2, and the front portion of packed-piston 2 is the hermetic terminal of frustum shape.The leading section of cavity 1 is corresponding hermetic terminal, and its hermetic terminal that is shaped as with packed-piston 2 matches, and also is the frustum shape.Being provided with a piston in the middle of cavity 1 hermetic terminal of this frustum shape remains silent, it is communicated in outer oil cavity body 5 by passage 6, one shifting bar 7 that is fixed on packed-piston 2 front, center passes this passage 6 after stretching out cavity 1, and by mobile pole socket 8 roof pressures a pull back spring 9 is arranged in its end, and the outer end roof pressure of this pull back spring 9 has the plug screw 10 of adjusting, also is equipped with cover of dust 11 outward.On outer oil cavity body 5, offer oil out port 12 in addition.
Fig. 2, oil-feed interface 3 of the present utility model is connected on the oil outlet pipe 14 of the master cylinder 13 in the brake system of car, and oil out port 12 is connected on the oil inlet 16 of brake cylinder 15, during use, when stepping on brake pedal 17, master cylinder 13 work, total pump piston 18 promotes the pipe inner fluid, make it to form high pressure, at a high speed oil enters piston cavity 1 from oil-feed interface 3, and enter outer oil cavity body 5 and brake cylinder 15 then respectively, and the sliding plug of brake cylinder 19 spreadings braking 20 makes brake strap 21 contact with braking wheel hub 22, produces friction.Because high pressure oil enters in the piston cavity 1, the packed-piston 2 that promotes in the cavity 1 moves forward, and promotion shifting bar 7 makes it to press pull back spring 9 generation compressions, when shifting bar promotes pull back spring 9 certain distances, the preceding hermetic terminal of packed-piston 2 contacts with hermetic terminal before the cavity 1, and produces sealing mutually.At this moment high pressure oil does not just advance outer oil cavity body 5, at this moment, brake cylinder 15 quits work, and the pull back spring 23 on the brake strap 21 unclamps shoe plate 21 and braking wheel hub 22, and the oil pressure that unclamps in the back outer oil cavity body 5 descends, pull back spring 23 resets, to pusher, make packed-piston 2 push away the hermetic terminal of cavity 1 front portion shifting bar 7, high-pressure oil passage is conducting again, the master cylinder oil pressure is delivered to piston cavity 1, outer oil cavity body 5 and brake cylinder 15 once more, and above-mentioned working cycle is carried out.The utility model is under the effect of oil pressure and spring, make shifting bar constantly reciprocating, constantly export transient pressure, this output frequency is in the speed of a motor vehicle per hour 50 kilometers the time, can reach 60-80 time, that is to say, when on the automobile master cylinder, loading onto device described in the utility model, when emergency brake, when wheel hub 22 is locking with shoe plate 21, can unclamp at once, check again after unclamping at once, automobile is on the transformation point of locking and not locking, and it cans be compared to experienced driver and runs into emergency brake when driving the coventional type automobile to take the principle of " point is stopped " be identical.It can make automobile under the situation of not locking, safety shut-down rapidly.
The utlity model has simple in structurely, easy to use, cost is low, and is safe and reliable, easy for installation, can have Avoid to effect the characteristics such as all traffic accidents that caused by emergency brake.
