Description
The utility model relates to the automotive oil automatic brake pump of system of stopping.
At present, the brake system of all kinds of self-propelled vehiclees is generally adopting oil this traditional brake modes of stopping, though this class brake modes is accepted extensively for people, but this class is divided into service brake and parking brake, this is obviously with regard to some inconvenience, and hand brake device also will occupy certain space in narrow and small operator's compartment, this has also increased inconvenience.
The purpose of this utility model provides a kind of automatic brake pump, and it is convenient to brake, and has reduced hand brake device, makes operator's compartment increase a bit valuable space relatively, and can prevent the automobile downhill coasting with engine off, the generation of minimizing accident.
Below in conjunction with accompanying drawing technical solution of the present utility model is described in detail.
Fig. 1 organigram of the present utility model.
According to shown in Figure 1, the utility model has the pump housing 19, on the pump housing 19 1 sidewalls, oil outlet 13 is arranged, on the relative sidewall of oil outlet 13, oil inlet 7 is arranged, the mobilizable electromagnet of iron core that is with locking coil 11 and pull in winding 12 is housed in the cavity in the pump housing 19, the iron core external part of electromagnet and valve one side fix, pull back spring 10 is arranged between valve and the electromagnet, oil inlet 7 has two by path, the another side of valve is over against living in hydraulic fluid port 7 one branch junctions, another by path and self-actuating brake oil circuit 3, side oil circuit 2 communicates, self-actuating brake oil circuit 3 and side oil circuit 2 are to parallel and do not communicate, self-actuating brake oil circuit 3 communicates with electric oil pump 4, electric oil pump 4 communicates with check valve 5 again, communicates with pump housing inner chamber through check valve 5, and pressure switch 6 also is housed on the pump housing.
Above-described valve is made up of valve disc 14, valve disc contact 8, valve disc contact 9, valve disc plug 20.
There is adjustable screw 1 by path and side oil circuit 2 junctions of the utility model oil inlet 7.
What be worth proposition is, the utility model has an adapted relay 21, a contact 16 in two contacts of relay 21 connects the brake pump binding post 15 of electromagnet by circuit, brake pump binding post 15 links to each other with a contact of locking coil 11 and pull in winding 12 respectively again, the mouth of locking coil 11 links to each other with ground wire, the mouth of pull in winding 12 links to each other with the valve disc contact 8 of valve, by valve disc 14 and valve disc contact 9 grounding jumpers, another contact 17 of adapted relay 21 links to each other with pressure switch 6, pressure switch 6 links to each other with a contact of electric oil pump 4 by circuit again, and another contact of electric oil pump 4 links to each other with ground wire by circuit.
The neutral of one termination electrical generator 23 of the coil of above-described relay 21, other end grounding jumper.
The cross bar that has spring of above-described relay of the present utility model 21 links to each other with battery 18 1 contacts, and an end points of cross bar is between contact 16 and contact 17.
Automatic brake pump of the present utility model can be used for all kinds of oil formula self-propelled vehicle of stopping, it is between the master cylinder and wheel cylinder that is connected in the motor-rehicle braking system, it uses principle of work to be, behind the engine starting, electrical generator 23 generating of promptly starting working, electric current promptly produces magnetic force through adapted relay 21, cross bar suction is downwards drawn, cross bar contacts with contact 16, this moment, the electric current of battery 18 promptly arrived automatic brake pump binding post 15 through cross bar by contact 16, the back enters pull in winding 12 and locking coil 11 respectively along two circuits, this moment, electromagnet produced magnetic attraction valve and compression retracteding position spring 10, because valve moves and arrives and make valve disc plug 20 leave oil inlet 7 to the electromagnet direction, because oil inlet 7 is opened, oil enters in the pump housing 19 and by oil outlet 13 and flows out.At this moment can use for the self-propelled vehicle walking.After the electromagnet direction moved, separated with the ground wire contact valve contact 9 at valve, has cut off the electric current of pull in winding 12, at this moment has only locking coil 11 to still have electric current, and electromagnet still can hold valve, so just can save battery power.When engine off, electrical generator 23 does not generate electricity, and the magnetic force of relay 21 disappears, cross bar leaves contact 16 under the pulling force of spring, cause the electromagnet no current, and magnetic force disappears, make the valve return under the effect of pull back spring 10, valve disc plug 20 is sealed a by path of oil inlet 7.Because leaving 16 backs, contact, cross bar joins with contact 17, the electric current of battery 18 just enters pressure switch 6 by cross bar, contact 17, and by after pressure switch 6 starts electric oil pump 4, output contact by electric oil pump 4 enters ground wire again, oil pressurization because electric oil pump 4 starts with self-actuating brake oil circuit 3 pumps into check valve 5, flow out automatic brake pumps and the wheel cylinder that enters motor-rehicle braking system through check valve 5 again, this oil circuit is the self-actuating brake oil circuit.Governing screw 1 can not start when needing trailer when preventing battery 18 power shortages establishes, and at this moment governing screw 1 is screwed out certain distance outside the pump housing 19 of automatic brake pump, can trailer and footbrake.This automatic brake pump is provided with filter at oil inlet 7 and oil outlet 13, and impurity such as the elimination dregs of fat and iron filings are to guarantee the self-actuating brake ability.
The utility model has the advantages that working as self-propelled vehicle one stops working, can self-actuating brake, the driver can easily be driven, also because no longer use parking brake this traditional mode and equipment, increased the space in the operator's compartment, spaciousness a bit makes the driver feel more comfortable, and automatic brake pump of the present utility model can be prevented the automobile downhill coasting with engine off simultaneously, has reduced the generation of accident.The utility model is cheap, and is easy to use, safe and reliable, especially the oil of existing self-propelled vehicle stopped system not as big change.Practical, be easy to promote.
