Abstract
The invention provides a vehicle safety braking device. The vehicle safety braking device comprises a parking braking pump, an active safety braking pump and a service braking pump, wherein a liquid outlet of the parking braking pump is connected to a liquid inlet of the active safety braking pump, a liquid outlet of the active safety braking pump is connected to a liquid inlet of the service braking pump, and a liquid outlet of the service braking pump is respectively connected to each wheel; and a hydraulic oil cylinder is sequentially connected with a normally-closed electromagnetic valve, an energy storage tank, an electric pump, a liquid storage tank and a normally-opened electromagnetic valve to form a hydraulic oil cylinder servo mechanism oil circuit, and the hydraulic oil cylinder is connected to a push rod of the active safety braking pump. The vehicle safety braking device generates high braking power equal to the service brake in extremely short time.
Description
Technical field:
The present invention relates to the safety catch of a kind of motor vehicles using hydraulic braking.
Background technology:
Self-actuating brake in existing active safety is essentially all and makes service brake pump push rod by some mechanisms
Stress and produce brake force, its structure is complicated, and reliability is low.
Summary of the invention:
It is further added by a set of active safety system among present invention tandem hydraulic pump type parking system in the prior art
Dynamic pump, this pump is identical with original service brake pump and parking braking pump population structure, the most independent between them,
It does not interfere with each other, and the powerful brake force being equal to service brake can be produced.When safety pre-warning system perceives
When having barrier in the safe distance that front relative velocity is corresponding, start hydraulic oil cylinder type servo control mechanism immediately, push away
The push rod of dynamic active safety brake pump produces brake force and reduces speed, until recovering again normal traveling after dangerous releasing.
Technical scheme is as follows:
Vehicle safety brake unit, including parking braking pump, active safety brake pump, service brake pump, parking
The liquid outlet of brake pump is connected to the inlet of active safety brake pump, and the liquid outlet of active safety brake pump connects
To the inlet of service brake pump, the liquid outlet of service brake pump is connected respectively to each wheel.
Hydraulic jack is sequentially connected with normally closed solenoid valve, energy storage canister, electrodynamic pump, fluid reservoir, normally open solenoid valve composition
Hydraulic oil cylinder type servo control mechanism oil circuit, hydraulic jack is connected to the push rod of active safety brake pump.
The invention has the beneficial effects as follows: the hydraulic oil cylinder type servo control mechanism in the present invention can produce electronic grade other
Incomparable quickly the responding of servo control mechanism of mode.And the active safety brake pump in the present invention also can be watched at this
Take in very short time, under mechanism's effect, produce the powerful brake force being equal to service brake.
Accompanying drawing illustrates:
Fig. 1 is the structure diagram of the present invention, wherein 1: parking braking pump；2: active safety brake pump；3:
Service brake pump；4: liquid outlet；5: inlet；6: push rod；7: hydraulic jack；8: normally closed solenoid valve；
9: normally open solenoid valve；10: energy storage canister；11: electrodynamic pump；12: fluid reservoir；13: service braking pedal；
14: wheel.
Detailed description of the invention:
Below by embodiment, and the invention will be further described to combine accompanying drawing.Vehicle safety brake unit
Including parking braking pump 1, active safety brake pump 2, service brake pump 3, the liquid outlet of parking braking pump 1
Being connected to the inlet of active safety brake pump 2, the liquid outlet of active safety brake pump 2 is connected to service brake
The inlet of pump 3, the liquid outlet of service brake pump 3 is connected respectively to each wheel 14.
Hydraulic jack 7 is sequentially connected with normally closed solenoid valve 8, energy storage canister 10, electrodynamic pump 11, fluid reservoir 12, often
Open electromagnetic valve 9 constitutes hydraulic oil cylinder type servo control mechanism oil circuit, and hydraulic jack 7 is connected to active safety brake pump 2
Push rod 6.
When the normally closed solenoid valve 8 in hydraulic oil cylinder type servo control mechanism oil circuit, normally open solenoid valve 9 obtain electric, make oil cylinder
When the pressurising of 7 moments promotes the push rod 6 of active safety brake pump, this power will pass through the fluid pressure line of brakes
It is delivered on the piston of four brake wheel cylinders, thus on four wheels, creates effect be equal to driving system
Dynamic powerful brake force.When electromagnetic valve 8, electromagnetic valve 9 dead electricity, oil cylinder pressure release, release braking.
