Description
Technical field
This utility model relates to a kind of control valve, particularly to a kind of control valve on Retarder.
Background technology
In prior art, using and have a kind of Retarder in brake and drive system for vehicle with tow, it is generally used for haulage vehicle, weight
Card, other hydraulic power vehicles etc. are large-scale or on heavy-duty vehicle.At present, European and American developed countries use commonplace, domestic general
Logical truck aspect was applied also in the starting stage, and in terms of hydraulic power vehicle, possible application is the most, and it is different from general drum
Stopping and disc brake, it is to be directly mounted at automobile gearbox output shaft.Utilize fluid damping power to provide output shaft of gear-box is subtracted
Turn of speed square, can persistently provide brake torque when heavy-duty vehicle long descending section.
For providing corresponding damping force, need to use combination of gases control valve to control to enter Retarder working area liquid
The flow of body, changes liquid damping force by flow thus changes retarding moment.The liquid measure entering working area is the most, vehicle speed
Spend the fastest (i.e. Retarder rotor speed is the highest) then retarding moment the biggest, on the contrary the least.It implements and is: gas group
Close control valve and promote a valve in Retarder by the pressure (being equivalent to proportional pressure valve) that different gear outputs are different
Core is in diverse location, at diverse location, this spool determines that different fluid floies (being equivalent to proportional flow control valve) enters work
District, its combination of gases control valve is equivalent to the pilot valve of hydraulic valve.During real work, human pilot is by regulation combination of gases control
The gear lever of valve processed makes brake weight strengthen or reduces so that vehicle can continue and stable brake in descending section, makes vehicle
It is in travel speed the most at the uniform velocity.
The parameter request difference of gas control valve both at home and abroad: actually used on the Retarder of external import is gas
Proportioning valve drive hydraulic valve, two valve is relatively independent but integrated installation is on Retarder body, the fluid power of domestic design delay
Speed device is improved because of domestic behaviour in service, have also been made adjustment in terms of control valve, and its hydraulic valve is integrated in Retarder
On, gas control valve is arranged on above driver's cabin or the crossbeam of vehicle.The liquid that current existing gas ratio valve designs at home
On power retarder, serviceability is the best, mainly two aspect problems: one be on domestic vehicles provide bleed pressure on the low side and
Pressure stability is poor；Two is domestic use road conditions difference, and one, long descending section, some mountain areas descent run may need super
High 40 minutes, it is desirable to Retarder provides stable damping torque this period, namely requires that gas control valve is very
Pressure stability is kept in long-time.Reaction be exactly in terms of specific performance parameter: repeatable accuracy, pressure maintaining performance, the linearity and slow
Stagnant characteristic requirements is the highest.
The use difference of Retarder both at home and abroad: the ratio of adaptability at home of the Retarder in the general truck of import
Poor, the most also to apply less, mainly this kind Retarder is primarily adapted for use in the truck of relatively low tonnage, and road
The situation that condition is relatively good, and domestic because Retarder is relatively costly, so not being willing the big overloading of truck using this device
Weight higher (generally more than 35t), and its traveling road conditions relatively severe (the descending brake of mountain area one vice-minister can exceed that 40 minutes),
The Retarder of import cannot be competent at both the above condition substantially.
