Abstract
The utility model relates to a safety device for brake fault. The utility model comprises a microswitch which is arranged on a brake oil cup and is used for reflecting the oil mass of the brake fault, and the microswitch is connected with a return circuit of a power supply for an igniter of an automobile in series. When the oil mass of the brake of the automobile drops to the oil mass of the brake fault, the microswitch is automatically cut off, so the igniter of the automobile is switched off, and a motor of the automobile stops working; thereby, the accident which is caused by the brake fault of the automobile can be effectively prevented.
Description
The utility model relates to 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 is to adopt the oil pressure brake, and oil mass is less to the phenomenon that brake failure to a certain degree will occur in the braking automobile lubricating cup.Existing brake failure prevent mean only is the brake failure acoustic-optic alarm, it is micro-switch and the acoustic-optic alarm that a reflection brake failure oil mass is set on the braking automobile lubricating cup, though it can remind the brake failure of automobilist's automobile, can not prevent the accident of brake failure to take place automatically.
The purpose of this utility model is achieved in that in that an open circuited micro-switch of normally closed contact when brake solution is reduced to the brake failure oil mass is set on the braking automobile lubricating cup, it is characterized in that this micro-switch is serially connected in the electric power loop of igniter for automobile.When the brake oil mass of automobile was reduced to the brake failure oil mass, micro-switch disconnected, and cut off the power supply of igniter for automobile, made automotive engine flame-out, thereby had prevented the generation of brake failure accident.
The utility model is simple in structure, and dependable performance can prevent the accident of brake failure in the running car automatically.
Fig. 1 is a scheme drawing of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in detail.
One end of slide bar 4 and the support 6 that is fixed on the bottom in the existing brake lubricating cup 2, captive joint overlaps with the axis of brake lubricating cup.The through hole at floating drum 3 middle parts is enclosed within on the slide bar 4, is connected a backguy 8 between the moving spring 1-1 of floating drum 3 and micro-switch 1; Micro-switch 1 is by moving spring 1-1, and quiet spring 1-2 forms, and screw passes the upper end that spring underframe 1-3 is fixed on micro-switch 1 brake lubricating cup 2 cups; Micro-switch 1 is serially connected in the electric power loop of igniter for automobile 7.
When oil mass just often, floating drum 3 come-up, moving spring 1-1, quiet spring 1-2 closure, the igniter for automobile energized, the automotive engine normal operation, when oil mass in the brake lubricating cup be normal oil level 1/5 the time (this moment brake failure), floating drum is floated downward and is driven backguy 8 pulling spring 1-1 downwards, with the moving spring 1-1 of micro-switch, quiet spring 1-2 separately cuts off the igniter for automobile power supply, make automobile flameout, thereby realized the purpose of brake failure insurance.
In the drawings, label 5 is the oil circuit of existing brake lubricating cup to master cylinder, and label 9 is an automobile power source, and label 10 is a brake solution.
The micro-switch of reflection brake failure described in the utility model also can adopt the micro-switch of existing brake failure acoustic-optic alarm.
Claims (2)
