Abstract
The utility model relates to a hydraulic braking system fault monitor, which belongs to the technical field of the safety monitoring device of the vehicle brake system. The hydraulic braking system fault monitor is provided with a casing and a magnetic induction element installed on the casing and electrically connected to an alarm device. An oil passage interface and an oil recess are processed in the casing, a slide block is installed in the cavity bore on the casing, a pressing screw plug is installed at the upper end of the cavity bore, a spring is installed between the pressing screw plug and the slide block, and a magnet is installed under the slide block. The personal sealing property of the utility model is good, and the hydraulic braking system fault monitor can be conveniently connected in an oil passage. When the decompression of the brake oil passage caused by leak or the breach of the oil pipe occurs, the hydraulic braking system fault monitor can cause drivers to find the fault in time to avoid the traffic accident caused by the poor stop or the braking distortion, and thus the driving security is enhanced.
Description
Affiliated technical field
The utility model relates to the safety monitoring assembly technical field of motor vehicle braking system, particularly relates to a kind of hydraulic vehicle brake fault locator.
Background technology
Hydraulic braking is the main brake mode of automobile, and existing vehicle mostly is not equipped with the safety monitoring assembly of brake system, when water clock or pipeline rupture appear in the brake solution road, cause the not enough or forfeiture of oil pressure, chaufeur perception in time, and can only just can realize the bad even brake failure of braking effect at glancing impact, very unfavorable to handling emergency situation, the possibility that causes traffic accident improves greatly.The patent No. is that 93236794.1 the automotive oil autoalarm of stopping is that thoughts reed pipe and magnet ball float are installed in lubricating cup, though certain caution effect is arranged, poor sensitivity, it is not prompt enough to report to the police.Though by the patent No. of the applicant invention is that 02288650.8 utility model patent has better detection effect, the self seal difficulty is big, occurs oil leakage phenomenon easily, and inconvenience is installed.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, provide a kind of safety performance good, easy for installation hydraulic brake system detector, make chaufeur timely and effectively the perception hydraulic brake system whether have fault, thereby timely trouble-shooting is avoided causing traffic accident because of poor stop or brake failure.
For achieving the above object, the technical scheme that the utility model adopted is: it has housing and the magnetic strength element that is electrically connected with warning device that is installed on the housing, be processed with oil circuit interface and the oil pocket that is connected each oil circuit interface in the housing, on housing, have the vestibule that the lower end communicates with oil pocket, slide block is installed in the vestibule, vestibule upper end is equipped with and compresses screw plug, compresses between screw plug and slide block spring is housed, and is equipped with and the cooresponding magnet of magnetic strength position of components below the slide block.
The utility model is equipped with gland below compressing screw plug, the slide block bearing is installed below the gland, and slide block is installed in below the slide block bearing and from its central authorities and passes, and magnet is installed in the barrier film.
The utility model self seal performance is good, can be connected easily in the oil circuit of hydraulic vehicle brake system, when hydraulic work system just often, under the oil pressure effect, magnet overcomes on the spring pressure together with slide block and moves, and the magnetic strength element breaks away from the magnet sphere of action and is in off-state.When brake circuit decompression occurs because of water clock or pipeline rupture, slide block drives magnet close magnetic strength element under action of the spring, make the magnetic strength element switches, send electric signal by circuit to warning device, thereby make chaufeur in time find fault, avoid causing traffic accident, improved travel safety because of poor stop or brake failure.
Description of drawings
Below by drawings and Examples the utility model is further described.
Accompanying drawing is a cutaway view of the present utility model, shows its integral structure.
The specific embodiment
In the embodiment that accompanying drawing provides, the utlity model has an all-in-one-piece housing 1, a tapped bore is arranged below the housing 1, the sensitive spring switch 2 that is electrically connected with warning device is installed in the hole, and tight by nut 3 back ofs the body.Be processed with oil circuit interface 4 that is connected with the hydraulic braking oil circuit and the oil pocket 5 that is connected each oil circuit interface 4 in the housing 1.Have the vestibule that the lower end communicates with oil pocket 5 on housing 1 top, the vestibule upper end is equipped with and compresses screw plug 8, the slide block 11 that can slide up and down is installed in the vestibule, slide block 11 is installed in below the slide block bearing 6 and from its central authorities and passes, slide block bearing 6 supports by being installed in the following gland 7 that compresses screw plug 8, spring perch 10 is equipped with in slide block 11 upper ends, compress 10 of screw plug 8 and spring perches spring 9 is housed, pad 13 is installed below the slide block 11, be equipped with below the pad 13 and the cooresponding magnet 14 in sensitive spring switch 2 positions, magnet 14 is installed in the barrier film 15, and the vestibule lower end is equipped with rubber seal 12.
