Abstract
The utility model discloses a trouble warner for hydraulic brake system which applies the electronic technology on automobile and can reflect a plurality of failures of the braking system. When the automobile is braked, the pedal downlink has a normal fixed position, and when the pedal downlink exceeds the extreme of the normal position, a failure of the braking system arises. The Figure K2 shows a displacement sense switch which can reflect the position of the brake pedal, when the brake pedal exceeds the normal position, the K2 is switched on, and an alarm device makes sounds to remind the driver that the braking system goes wrong or work irregularly.
Description
The present invention is used for hydraulic vehicle braking mechanism with Eltec, the device of a lot of faults of reaction brake system.
By looking into 78 years, there is not identical invention to 84 years " vehicular transport ", " automotive technology ", " external vehicular transport ".Nearest day the present invention's braking liquid leakage alarms device, its principle of work is different with structure with the present invention and prior art is distinguishing.
In the prior art, its brake system of hydraulic braking automobile often has some big glitch.Increase (gap is not very big) such as the brake wheel gap owing to wear and tear.This fault chaufeur generally is difficult for realizing because what reaction it does not have, be brake action should increase a bit if having time.The position of brake pedal has moved down a bit.Do not come so feel during from footbrake.But this fault also can bring serious accident to take place sometimes.Cross highway such as a child, brake system just often brakes immediately, can not strike the beam, if brake clearance is big, chaufeur braked in the identical time, and this child will strike the beam.And for example automobile travels in the mountain area, because lower long slope, the high temperature of brake wheel can make brake solution produce a part of vaporization, can cause brake failure.But the driver often can not find that when having vaporized many, braking is just known near malfunctioning.Because it is step by step that brake solution produces vaporization phenomenon.Also have the not serious leakage of oil of each wheel cylinder etc., these all are easy to generate, but chaufeur also is not easy to find.
The present invention is in order to solve when the above-mentioned situation, as long as fault one occurs, just notes by the annunciator prompting chaufeur of sounding, and in time brake system overhauled, and can reduce some traffic accident accidents.Ad hocly counted a kind of hydraulic brake failure annunciator.
Accompanying drawing is the circuit structure diagram of expression hydraulic brake failure annunciator.K
1Be source switch, K
2It is the displacement sensing switch.Work as K
2Loud speaker is just sounded when closed.Glancing impact, the descending position of pedal have a fixing normal position, have crossed the normal position, and just illustrating has fault K in the brake system
2With regard to conducting.Brake noise is incoercible, and after each brake cylinder was full of oil, brake noise was the same with solid, only plays the size effect of transmission power, so pedal is descending a fixed position is arranged.(this is meant when whenever stepping on a foot brake that except stepping on continuously soon, but brake just often there is no need to step on continuously brake).The rising-heat contracting-cold of environment can not influence the fixedly normal position of pedal, because of the piston of master brake cylinder is connected in the middle of the brake noise.If brake pedal has surpassed the entopic limit, just illustrating has fault in the brake system.Such as, braking oil starvation, master cylinder wearing and tearing, leather cup is bad and damages, each brake cylinder wearing and tearing, leather cup damage, leakage of oil, brake wheel gap increase, brake plate damage, each wheel cylinder in air or the like is arranged.
The present invention's accident that can cut down traffic accidents reduces people's life and property loss, and structure is simple (more than ten yuan of money) especially, uses, installation, maintenance is extremely convenient, brake failure had the effect of knowing in early days.Because cause the major break down of brake failure, it some glitch phenomenons are just arranged in early days, this is as you know, can not be quickly from normal fully brake, brake failure suddenly.When often these glitch took place, people were difficult for finding it, if after loading onto annunciator, just can be in time found.
With K
2Be fixed in the operator's compartment, its movable contact be pressed on the arm of brake pedal that (position should be movable adjustable) is entopic decides method: brake pedal is stepped on earth (will fully just often) at brake system.At first adjust K
2Allow its switch contact closure, and then recall to the gap that makes 3 to 5 millimeters of contact opens (come according to each vehicle fixed).Before going out car at every turn, can step on slipper, brake system is tested, the explanation brake system is abnormal substantially if do not report to the police this moment, can be K during driving
1Connecting, can test to brake system at any time, is exactly whenever to step on a foot brake just to know its service condition.
Claims (1)
- A kind of by two switch (K 1K 2) and the annunciator that the tone level oscillator is formed.It is characterized in that: it has a displacement sensing switch (K 2).
