Liquid inlet electromagnetic valve 12.6 and liquid outlet electromagnetic valve 12.7 are set respectively on 12.5, as electric-controlled switch.
The retarding braking process of automobile using fluid damping formula brakes of the present invention is as follows：
During normal operation, the first hydraulic switching valve 9a and the second hydraulic switching valve 9b are in open mode, work as automobile front driving
When running into emergency needs braking, brake actuator 13 is manually stepped on, i.e. braking is foot-operated, and car running computer (ECU) will be urgent
Brake signal exports to be opened to liquid inlet electromagnetic valve 12.6 and liquid outlet electromagnetic valve 12.7, liquid inlet electromagnetic valve 12.6, liquid outlet electromagnetic valve
12.7 closing, driving liquid feed liquor enters the first hydraulic switching valve 9a, and the first hydraulic switching valve 9a apertures are gradually reduced until closing.
Because the first hydraulic switching valve 9a is closed, circulating for brake fluid is obstructed, and the brake fluid sealing circulation discharged in gear-box is logical
The pressure in road gradually rises, and the reaction force that gear page when gear engagement rotates is subject to incrementally increases, and gear rotational speed is gradual
Slack-off, the rotating speed of Automobile shaft 15 reduces, until stopping.Braked during reversing, the second hydraulic switching valve 9b closing is worked, and it is former
Reason is same as above.
In actual application, because automobile normal forward duration is longer, it is contemplated that brake fluid is being braked
Circulation for a long time can cause brake fluid temperature factor, the system that can be corresponding in automobile normal forward such as to rise in liquid circulation canal
Hydrodynamic, which enters in the connecting tube of gear-box, sets magnetic valve, and the magnetic valve is controlled by car running computer (ECU), when automobile normal forward
When, the closed electromagnetic valve, circulate, be finally reached so as to control brake fluid not enter in the case of automobile normal forward in gear-box
Avoid influenceing caused by brake fluid long-time rotation flowing；When run into emergency need braking when, the magnetic valve is driven a vehicle
Computer (ECU) is controlled, and the magnetic valve is opened, and brake fluid enters gear-box, passes through circulating the brake fluid in gear-box
Resistance prevent brake axle from rotating, and then the purpose braked.
The realization of anti-lock braking system (ABS)：Automobile using fluid damping formula brakes of the present invention is also by feed liquor
Set liquid inlet electromagnetic valve 12.6 and liquid outlet electromagnetic valve 12.7 to realize on pipe 12.4 and drain pipe 12.5 respectively, piston cylinder 12.3 with
Electrodynamic pump 12.2 is provided between fluid reservoir 12.1, when car speed drops to setting value, car running computer (ECU) sends instruction,
Liquid inlet electromagnetic valve 12.6, the entrance of cut-out driving liquid are closed, while opens driving liquid liquid outlet electromagnetic valve 12.7, the first hydraulic pressure is opened
Close valve 9a, the driving liquid of the second hydraulic switching valve 9b intracavitary drains into driving liquid fluid reservoir 12.1；Meanwhile the first hydraulic switching valve 9a
Opened respectively in the presence of back-moving spring with the second hydraulic switching valve 9b, braking disappears immediately.
Train speed reducing braking is similar with car deceleration braking principle.
The difference of the train fluid damping formula brakes and automobile using fluid damping formula brakes of the present invention is
Below some：(1) in the setting of hydraulic switching valve, with automobile on the contrary, train two hydraulic switching valves 9a, 9b original state
To close.When train normal operation, the first hydraulic switching valve 9a and the second hydraulic switching valve are controlled by brake control mechanism 12
9b is in open mode；When needing retarding braking, brake actuator (13) is that train control system sends braking instruction, is opened
Begin to operate：Liquid inlet electromagnetic valve 12.6, the entrance of cut-out driving liquid are closed, while opens driving liquid liquid outlet electromagnetic valve 12.7, by the
One hydraulic switching valve 9a, the driving liquid of the second hydraulic switching valve 9b intracavitary drain into driving liquid fluid reservoir 12.1；Meanwhile first hydraulic pressure
Switch valve 9a and the second hydraulic switching valve 9b reset in the presence of back-moving spring respectively, the first hydraulic switching valve 9a and the second liquid
The valve 9b that compresses switch is closed, and realizes braking.(2) in the setting of brake fluid liquid reserve tank 8, in train fluid damping formula brakes
The gear-box of the same bogie homonymy of each column train shares a brake fluid liquid reserve tank 8.(3) when train carriage needs individually for a long time
When parking, operable braking parking brake 18 realizes braking purpose.
The fluid damping formula brakes of the present invention can control the first hydraulic selector by piston cylinder 12.3 as the case may be
Valve 9a and the second hydraulic switching valve 9b process that closing is progressively decreased up to by standard-sized sheet, so as to control the braking of brake axle fast
Degree, can form any braking characteristic curve needed for equipment, meet to be actually needed.
Embodiment above describes the general principle and principal character and advantages of the present invention of the present invention.The technology of the industry
Personnel are to be tied based on gear pump in pump class it should be appreciated that the present invention is to be applied to brake field after gear pump structure is improved
Structure is simple, and manufacturing cost is low, good braking effect, has a extensive future, and has a very strong market competitiveness, but the guarantor of the present invention
Shield scope is not restricted to the described embodiments, the letter done such as principle of the similar pump class of other structures based on the present invention and method
Single transformation, the structure of brake switch valve and position, the concrete mode of brake control mechanism can be selected arbitrarily, as long as using this
The principle of invention, is obstructed using fluid circulation, and resistance is transformed into the effect that brake force reaches braking, of the invention total not departing from
Spirit and scope on the premise of, various changes and modifications of the present invention are possible, and these changes and improvements belong to claimed
The scope of the invention in.
