Among the figure, 1 is the end filter screen, and 2 is catch, 3 is steel ball, and 4 is one-way valve seat, and 5 is O-ring seals, 6 is the pressure charging valve valve seat, and 7 are the ring filter screen, and 8 is valve pocket, 9 is pressure adjusting spring, and 10 is electromagnetic valve body, and 11 for deciding iron, 12 is Returnning spring, and 13 is valve rod, and 14 are moving iron, 15 is plunger tube, 16 is liquid entering hole, and 17 is liquid outlet, and 18 is fluid pressure governor, 19 is vacuum solenoid valve, 20 is that boost electromagnetic valve, 21 is coil, and 22 is throttle orifice, and 23 is throttling groove, 24 is throttling pore, and 25 is two symmetry plane structures of pressure charging valve valve seat bottom.
Embodiment
The present invention places the catch 2 in the electromagnetic valve body 10 from bottom to top mainly by electromagnetic valve body 10, the one-way valve seat 4 of band steel ball 3, the pressure charging valve valve seat 6 of band O-ring seals 5, the valve pocket 8 of band pressure adjusting spring 9 is decided iron 11, Returnning spring 12, the moving iron 14 of band valve rod 13, plunger tube 15 formations such as grade; The cylndrical surface of pressure charging valve valve seat 6 bottoms is two symmetry plane structures 25, and connects with electromagnetic valve body 10 rivetings; The top of valve pocket 8 is provided with throttling groove 23 or throttling pore 24; Catch 2 is provided with throttle orifice 22, and adopts interference fit joint with electromagnetic valve body; The liquid entering hole of electromagnetic valve body 10 bottoms and the liquid outlet of outer side surface are provided with end filter screen 1 and the ring filter screen 7 of 400 orders/in respectively, can effectively stop molecule to enter valve inner, prevent the smooth or obstruction of runner; Catch 2, one-way valve seat 4, pressure charging valve valve seat 6 all adopt the interference combination with electromagnetic valve body 10, have improved connection reliability and sealing.
During work, as shown in Figure 3, the present invention is installed on the fluid pressure governor 18 that installs vacuum solenoid valve 19, brake fluid enters the liquid entering hole 16 of fluid pressure governor 18 by master cylinder, and after end filter screen 1 filters, by the throttle orifice on the catch 2 22, enter boost electromagnetic valve 20 inside, at this moment, because under the action of hydraulic force, steel ball 3 is in closed condition with one-way valve seat 4, and symmetry plane 25 on valve port by pressure charging valve valve seat 6 and the cylndrical surface, respectively by the ring filter screen 7 flow through liquid outlet 17 and O-ring seals 5 cavity of resorption (at this moment, because hydraulic difference is less than the pre-elastic force of pressure adjusting spring 9 between liquid entering hole 16 and the liquid outlet 17, O-ring seals 5 and valve pocket 8 remain static), liquid outlet 17 links to each other with wheel cylinder, make the big flow feed flow of wheel cylinder, finish conventional brake.
In the conventional brake process, when wheel speed sensors detects certain wheel locking trend is arranged, controller is immediately to coil 21 energising work, the moving iron 14 of boost electromagnetic valve 20 is under the magnetic force effect, overcome the pre-elastic force of Returnning spring 12, driving valve rod 13 moves downward, close the valve port of pressure charging valve valve seat 6, realize that the wheel cylinder hydraulic coupling keeps (at this moment, because hydraulic difference is greater than the pre-elastic force of pressure adjusting spring 9 between liquid entering hole 16 and the liquid outlet 17, the pre-elastic force that O-ring seals 5 and valve pocket 8 overcome pressure adjusting spring 9 moves upward, and contacts with the sphere of deciding iron 11 until valve pocket 8); When wheel speed sensors according to wheel velocity signal, judge when wheel cylinder still has supercharging possible, controller is to coil 21 outages, the moving iron 14 of boost electromagnetic valve 20 is being eliminated under the magnetic force situation, under the resilient force of Returnning spring 12, drive valve rod 13 and move upward, open the valve port of pressure charging valve valve seat 6; Brake fluid flows to wheel cylinder (at this moment by the throttling groove 23 on the throttle orifice on the catch 2 22, pressure charging valve valve seat 6 valve ports, the valve pocket 8 or throttling pore 24, liquid outlet 17, because the long-pending cross section of fluid channel less than the throttle orifice on the catch 2 22 of the throttling groove 23 on the valve pocket 8 or the cross section of fluid channel of throttling pore 24 is long-pending), realize the small flow feed flow, be convenient to accurate control rate of pressurization.
Describe according to working principle, required these two requirements of less hydraulic booster speed when the present invention has realized bigger hydraulic booster speed required when conventional brake and abs braking fully, thus reach designing requirement.
