Embodiment 1

[0039] like image 3 As shown, the automobile hydraulic brake system leakage, leakage alarm protection device and installation method thereof of the present invention are composed of a double-core valve body part A, a sensor part B, an electronic circuit alarm system C, and a display panel D. It is characterized in that the sensor Part B is installed in the installation hole 5 on the double core valve body part A, the signal output end of the sensor part B is connected with the electronic circuit alarm system C, and the electronic circuit alarm system C is connected with the display panel D.

[0040] Double-core valve body part A is composed of double-core valve housing 1, plugging cap 2, circlip 3, oil inlet hole 4, installation hole 5, leakage cavity a, leakage pressure differential piston assembly a1, leakage process positioning Screw 6, oil outlet hole 7, leakage chamber b, leakage pressure differential piston assembly b1, leakage transition joint 8, leakage process positi...

Embodiment 2

[0050] like Figure 8 The leakage and leakage alarm protection device and installation method of the automobile hydraulic brake system shown in the figure only need to make four installation holes 5 and two oil outlet holes 7 on the double core valve casing 1 of the double core valve body part A. Figure 8 The style of all the other parts, principle, effect, structure and installation method are identical with embodiment one.

Embodiment 3

[0052] like Figure 9 The leakage of the automobile hydraulic brake system shown, the leakage alarm protection device and its installation method, only need to put Figure 8 The sensor part 2 is replaced by a pressure sensor, and the name, principle, effect, structure and installation method of other parts are the same as those in the first embodiment.

Abstract

The invention relates to the field of active safety of vehicles, in particular to an alarm protective device for seepage and leakage of a hydraulic braking system of the vehicles and an installation method thereof. The device is composed of a double-valve-core body component A, a sensor component B, an electronic circuit alarm system C and a display panel D. The invention has the advantages that the efficiency of an emergency light of the hydraulic braking of the vehicles is extended, and a protective device which is added is capable of not only discriminatively alarming for faults of the seepage and the leakage with different degrees, but also emergently alarming for the braking system with seepage faults and automatically starting to work under protected state, thereby increasing safety for automatic driving automobiles. And the alarm protective device is simple in structure and convenient in installation.

Description

technical field [0001] The invention relates to the field of automobile active safety, in particular to a device for alarming and protecting when the hydraulic brake system of the automobile leaks and leaks. Background technique [0002] The brake fluid leakage of the automobile hydraulic braking system is one of the common faults of the automobile hydraulic braking system. There are many reasons for the failure, which can be divided into two types according to the degree of failure: leakage and leakage. The automobile hydraulic brake fault signal generators that have been widely used now, some use the brake fluid to leak out, and when the brake fluid in the oil cup is lower than the warning line, the brake fault signal light is turned on, and some use the brake fluid to leak out. Leakage, the pressure difference that produces turns on the brake fault signal light, the above-mentioned various methods can only be a kind of display after the brake fluid leaks (fault is commonl...
