Description
Technical field
The utility model relates to power unit trailer one solenoid valve in a kind of braking automobile anti-lock ABS product, is specifically applied to the ABS system of trailer.
Background technique
Trailer one solenoid valve is the crucial power unit in trailer brake anti-blocking ABS system, and its development is that the development that is accompanied by ABS technology gets up.China promulgated the mandatory rules of law in 1999, required ABS system was installed in part vehicle in 2003, through the research more than 10 years, test, and mass test, it is ripe that ABS product has been tending towards now more.ABS system chief component has: wheel speed sensors, ECU Direct box, solenoid valve etc.ECU Direct box is by receiving the signal of the inputs such as wheel speed sensors, controlled wheel made in braking process is carried out to motion state monitoring, the air-suction state of controlling solenoid valve, regulates retardation pressure as required, makes controlled vehicle all the time in desired slip state.
GB GB7258-2004 requires: " gross mass is greater than coach and the sightseeing bus of 12000kg, and gross mass is greater than 16OOOkg and allows to articulate that gross mass is greater than the lorry of trailer of 10000kg and the trailer that gross mass is greater than 10000kg must be installed the anti-lock brake system that meets GB/T13594-2003 regulation ".
Trailer ABS from 26S Proteasome Structure and Function with some difference of passenger vehicle ABS, trailer one solenoid valve is the modular product being exclusively used on trailer ABS, combining with ECU, is a Twin channel modulating valve, can in ABS circulation, control two almost completely independently retardation pressures.In order to regulate pressure, three solenoid valves are integrated.The air pipe of trailer integral valve comprises suction port, and relief opening is controlled mouth and brake chamber interface.
In current ABS product, as depicted in figs. 1 and 2, the problem of its existence is gas leakage and job insecurity to piston type trailer one solenoid valve.
Piston type trailer one solenoid valve, is mainly used in, in trailer brake anti-blocking ABS product, having nine mouths at present, 200, one relief openings 300 of 100, six brake chamber interfaces of a gas source interface (suction port), control mouth 400 for one, brake chamber interface 2 is totally six places; The working principle of piston type trailer one solenoid valve is by suction port 100 normal open gas, give and control after mouthful 400 ventilations, the high-pressure air of controlling mouth 400 promotes the piston compression leg in air chamber, compression retracteding position spring, then compression leg is depressed suction port 100 and the interchannel seal ring 3 of brake chamber interface 200, suction port 100 and brake chamber interface 200 are communicated, and high-pressure air is from brake chamber 200 to each brake air chamber; Seal ring 3 times is position spring once, controlling under mouthful 400 stuffiness states, seal ring 3 under return spring 2 elastic force effects, the gas channels of blocking-up suction port 100 and brake chamber interface 200.
In sum, the working condition of piston compression leg in air chamber, directly determines that can suction port 100 gas circuits press enough and reaches in time brake chamber 200, then controls brake air chamber.The universal way of controlling at present suction port 100 and brake chamber interface 200 gas path on-offs is that piston type compression leg is controlled, in piston type compression leg outer peripheral surface upper groove, pack Z-shaped seal ring 10 into, compression leg endwisely slips in the inner side of valve body air chamber, by Z-type seal ring 10 and the friction of air chamber inner slide.Piston compression leg side in air chamber communicates with control mouth 400, and opposite side communicates with brake chamber interface 200, and compression leg head is close to seal ring.During integrated valve assembling, smear in lubricating grease pusher air inlet chamber housing on the Z-shaped seal ring of piston compression leg, lubricating grease plays good lubrication effect.
The shortcoming of above-mentioned piston type trailer one solenoid valve is that piston compression leg axial rub on valve side air chamber inside circumference face slides, on piston compression leg, Z-type seal ring and air chamber inside circumference face area of contact are larger, frictional force is larger, if grease lubrication is bad, or in the situations such as lubricating grease is dried for a long time, will cause Z-type ring wear, control mouthful rear compressed air leakage of 400 ventilation to brake chamber interface 200; Or piston compression leg clamping stagnation, in air chamber, can not be pushed open completely or can not push seal ring open, cause brake chamber 200 to go out unsaturated vapor, or pressurized air is leaked to relief opening 300 from suction port 100.
Model utility content
Technical problem to be solved in the utility model is for above-mentioned deficiency of the prior art, and a kind of trailer one solenoid valve of air tight and working stability is provided.
The utility model solves the technological scheme that its technical problem adopts: diaphragm type trailer one solenoid valve, comprise valve body, the air chamber being surrounded by air chamber end cap, suction port, brake chamber interface, relief opening and control mouthful, also comprises the seal ring that is communicated with suction port and brake chamber interface gas channels after compression and blocks suction port and brake chamber interface gas channels after return, and seal ring is between suction port and brake chamber interface;
Above-mentioned seal ring is installed diaphragm type compression leg away from a side of valve body, the compression leg head of diaphragm type compression leg is close to seal ring, the edge of diaphragm type compression leg is fixed between air chamber and valve body by primary diaphragm fixed component and secondary diaphragm fixed component, diaphragm type compression leg side in air chamber communicates with control mouthful, opposite side and brake chamber interface communicate, and primary diaphragm fixed component and secondary diaphragm fixed component are separately positioned on the both sides at diaphragm type compression leg edge;
Above-mentioned seal ring is installed and is used for the return spring of seal ring return near a side of valve body, and support ring is installed in the end of return spring.
Further: above-mentioned brake chamber interface one has six, described suction port, relief opening and control mouthful respectively have one.
Further: above-mentioned secondary diaphragm fixed component and air chamber madial wall connecting part are provided with O type circle, the compression leg head of diaphragm type compression leg outside is provided with limited ring.
The utility model compared with prior art has the following advantages:
In the utility model structure owing to being diaphragm type compression leg, pressure reduction by chamber, air chamber interior diaphragm left and right is depressed seal ring, so do not need to increase lubricating grease, there is not friction pair yet, do not exist the Y-axis of Z-shaped seal ring to fricting movement, guaranteed that diaphragm type compression leg contacts well with seal ring, solved valve gas leakage and valve job insecurity problem.
The utility model flexibility is good, and the integrated valve of diaphragm type only exists the power of self-deformation generation and the elastic force of return spring during motion of membrane, be not in addition subject to other External force interference, can fully ensure the flexibility of its motion.
