Abstract
The utility model relates to an automobile safety device, particularly a safety device for the braking failure of medium-sized and small-sized automobiles. The utility model comprises a microswitch which is arranged on a braking oil cup, and the normally-closed contact of the microswitch is switched off when the braking oil drops to the oil mass of the braking failure. The microswitch is connected with a normally closed electromagnetic valve in series, and the normally closed electromagnetic valve is installed on an oil conveying pipe. The utility model has the advantages of simple structure and reliable performance. By using the utility model, the accident of the braking failure of the automobile can be automatically and effectively prevented when the automobile is in action. The utility model is suitable for the medium-sized and the small-sized automobiles of various engines.
Description
The utility model is the brake failure safety device of a kind of auto-safety mechanism, particularly a kind of small and medium-sized car.
Small and medium-sized car all is to adopt the oil pressure brake.When the oil mass in the braking automobile lubricating cup arrives to a certain degree less, will the phenomenon of brake failure appear.
Existing brake failure prevent mean only is the brake failure acoustic-optic alarm, and it is micro-switch and the acoustic-optic alarm that a reflection brake failure oil mass is set on the braking automobile lubricating cup.
Existing brake failure prevent mean though can remind the brake failure of automobilist's automobile, can not prevent the accident of brake failure to take place automatically.
The inventor was that denomination of invention proposed a utility application to Patent Office of the People's Republic of China with " brake failure safety device " once on October 11st, 1993, application number 93241415.X.The meter notice is stepped in the mandate that this application has been received Patent Office of the People's Republic of China on May 3rd, 1994, and has received patent certificate on July 11st, 1994.
In above-mentioned application, the inventor discloses a kind of brake failure safety device that is used to use the small and medium-sized car of Gasoline engine, connect with igniter for automobile with the open circuited micro-switch of normally closed contact when brake solution is reduced to the brake failure oil mass that is contained on the brake lubricating cup, the power supply of automatic point of cutoff firearm stops burning engine when the oil mass in the brake lubricating cup is reduced to the brake failure oil mass, realizes the insurance of brake failure.
But present some senior roadlices that use as later-model benz car etc., use Diesel Engine, and these Diesel Engines adopt presses quick-friedly, does not have firing unit.
The purpose of this utility model is to design a kind of later-model brake failure safety device, cuts off delivery line automatically when the oil mass in the brake lubricating cup drops to the brake failure oil mass engine is stopped burning, and realizes the brake failure insurance.
The utility model comprises an open circuited micro-switch of normally closed contact when brake solution is reduced to the brake failure oil mass that is arranged on the brake lubricating cup, and this micro-switch is connected with the normally closed solenoid valve on being contained in transport pipe.
When the brake solution in the brake lubricating cup dropped to the brake failure oil mass, micro-switch disconnected, thereby cut off the power supply of electromagnetic valve, cut off delivery line, caused engine to stop burning.
The utility model is simple in structure, and dependable performance can actv. prevents the generation of brake failure accident in the running car automatically, not only is specially adapted to use the small and medium-sized car of Diesel Engine, also is applicable to the small and medium-sized car that uses Gasoline engine fully.
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is a general illustration.
In the accompanying drawings, the 5th, have the oil circuit of brake lubricating cup now to master cylinder, the 9th, automobile power source, 10 is brake solution.
In this embodiment,
The lower end of slide bar (4) is fixed on the support (6) that is fixed in existing brake lubricating cup (2) inner bottom part, the through hole at floating drum (3) middle part is enclosed within on the slide bar (4), is connected with a backguy (8) between the moving spring (1-1) of floating drum (3) and micro-switch (1); Micro-switch (1) is made up of moving spring (1-1) and quiet spring (1-2), and screw passes the upper end that spring underframe (1-3) is fixed on micro-switch (1) brake lubricating cup (2).Micro-switch (1) is connected with the electromagnetic valve (7) on being contained in transport pipe.
When oil mass just often, floating drum (3) come-up, moving spring (1-1) and quiet spring (1-2) closure, electromagnetic valve (7) powers on and opens, engine is normally just done.
When the oil mass in brake lubricating cup (2) be normal oil level 1/5 the time, brake failure, floating drum (3) is floated downward and is driven backguy (8) and spur spring (1-1) downwards, the moving spring (1-1) and the quiet spring (1-2) of micro-switch (1) are separated, cut off the power supply of electromagnetic valve (7), electromagnetic valve (7) power-failure close cuts off oil circuit, and engine is stopped burning, thereby realizes the malfunctioning insurance of braking automobile.
Claims (1)
1, brake failure safety device, comprise an open circuited micro-switch of normally closed contact (1) when brake solution (10) is reduced to the brake failure oil mass that is arranged on the brake lubricating cup (2), it is characterized in that: this micro-switch (1) is connected with the normally closed solenoid valve (7) on being contained in transport pipe.
