Summary of the invention:
The purpose of this utility model provides a kind of master brake cylinder that utilizes makes automobile have the anti-theft type master brake cylinder assembly of whole antitheft effect.
The technical solution of the utility model is finished as follows, it includes hydraulic braking master cylinder for automobile, it is characterized in that: two oil mains line are vertically installed with an electromagnetic plunger valve in the master brake cylinder housing, the electronic control board of electromagnetic plunger valve be installed in one with control capsule that the assembly housing links to each other in, control capsule is provided with the wire nipple that connects automobile ignition switch and storage battery, be equipped with one with the plunger locking of electromagnetic plunger valve or the automatic holding device of release on total pump case between the armature of electromagnetic plunger valve and the plunger, there is retracing spring the rear end of plunger in the top in total pump case, the plunger central axis is provided with through hole, in housing, be communicated with secondary oil duct respectively in that plunger and two oil main line intersections are parallel with oil main line, be respectively equipped with check valve between each secondary oil duct and the oil main line.
The utility model utilizes master brake cylinder to realize the whole antitheft of automobile, it is simple in structure, easy to use, theftproof performance is reliable, during parking, as long as use this device, four-wheel can be locked, finish synchronously stop antitheft with car load, make that master cylinder can prevent to take to relocate, wire jumper, make contact, change parts, duplicate password, decryption, shielding means or with drag, the way of go-cart steals whole automobile.Break through the single effect of master brake cylinder, be applicable to all vehicles of hydraulic braking.
Description of drawings:
Fig. 1 is a structural representation of the present utility model; Fig. 2 is the c-c cutaway view of Fig. 1; Fig. 3 is the d-d cutaway view of Fig. 1; Fig. 4 is a fundamental diagram of the present utility model.
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing.The utility model is the improvement to the master brake cylinder of existing automobile, it includes master brake cylinder 2 and its oil storage kettle 1, its improvements be in the master brake cylinder housing with electromagnetic plunger valve of two vertical installations of oil main line, the electronic control board 4 of electromagnetic plunger valve be installed in one with control capsule 3 that total pump case links to each other in, control capsule is provided with the wire nipple 5 that connects automobile ignition switch 25 and storage battery 26, be equipped with one with the plunger locking of electromagnetic plunger valve or the automatic holding device 7 of release on total pump case between the stage clip 6-3 of the armature 6-2 of electromagnetic plunger valve 6, plunger back-end has retracing spring 17 with the interior top of total pump case, the plunger central axis is provided with through hole 6-5, be provided with circular groove 6-4 at plunger and two oil duct intersections, parallelly with two oil mains line in housing, be communicated with secondary oil duct 18 respectively, be respectively equipped with check valve 11 and 16 between each secondary oil duct and the oil main line, each check valve has spring 9 respectively, 14 and plug 10,15 form.Be connected on two oil main line interfaces 8,13 respectively with two oil pipes during installation and front and back connect between the branch oil pump 21,22,23,24 of wheel, be connected between control capsule and the ignition lock 25 and with two leads 19,20 simultaneously and be communicated with accumulate bottle 26.Its principle of work is on the basis of existing hydraulic braking master cylinder for automobile assembly electromagnetic plunger valve, automatic holding device, check valve and Electronic Control Box to be set, the automatic holding device is a prior art, China Patent No. is 2005200311933, the automatic holding device makes magnet coil startup, moment electricity consumption when closing, not electricity consumption when work or inoperative is not generated heat device and is difficult for wearing out.Under the normal circumstances, two circular grooves of plunger and a on the master brake cylinder, two oil mains line in b chamber are relative, make master brake cylinder a, b chamber and front and back brake cylinder 21,22,23,24 are communicated with, driver operation is with original the same, when stopping, give the brake system supercharging during with the brake pedal ramp to stop, when not decontroling brake pedal, keep closing ignition lock conveniently under the supercharging situation, make each brake cylinder of electromagnetic plunger valve closure lead to master cylinder a, two oil mains line in b chamber, the interior high pressure oil of this moment brake cylinder and oil pipe can not return in the oil storage kettle 1, each wheel is firmly braked, so close the moment of ignition lock 25, just triggered the electromagnetic plunger valve, armature inwardly slides, the last pilot bar that promotes the automatic holding device inwardly slides, last pilot bar promotes down pilot bar again and inwardly slides, the angle of reversing the orienting sleeve deep trouth that the key of following pilot bar skids off the automatic holding device slips into the automatic holding device and leads and be lockable in the shallow slot of lock sleeve, plunger must not be returned, the retracing spring 17 of the other end of plunger is compressed, at this moment the inside length of sliding of plunger surpasses and the corresponding circular groove width of oil main line, brake cylinder leads to master cylinder a before and after having sealed, the b chamber makes wheel still be in braking mode to the path of master cylinder and oil storage kettle; Receive code signal through inter-process confirm after work with binary pair, triggering inductor, controller this moment, disconnects the power supply of the magnet coil 6-1 in the control capsule, and vehicle enters anti-theft state.At this moment, even cartheft can start driving engine, can not drive away their vehicles; Also can not drag car away, more can not push away away car with manpower.If there is not brake-apply when the driver is stopped, as long as closed ignition lock, taken off key, just triggered electromagnetic plunger valve circuit, the electromagnetic plunger valve has just cut out the oil main line that brake cylinder is led in master brake cylinder a, b chamber, just brake system does not form the high pressure braking oil pressure, wheel also is in state free to rotate, but entered accurate anti-theft state, at this moment in a single day step on brake pedal, the hydraulic oil in master brake cylinder a, b chamber will back down the check valve on the secondary oil duct, enter into each brake cylinder through secondary oil duct, with wheel braking, can not rotate again.During releasing, at first trigger and connect electromagnetic coil circuit with electron key; Then open ignition lock, make electromagnetic plunger valve return, the brake circuit that is closed is opened, wheel is just rotatable.
