Abstract
This utility model provides a kind of vehicle safety brake unit, it includes parking braking pump, active safety brake pump, service brake pump, the liquid outlet of parking braking pump is connected to the inlet of active safety brake pump, the liquid outlet of active safety brake pump is connected to the inlet of service brake pump, and 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, and hydraulic jack is connected to the push rod of active safety brake pump.Vehicle safety brake unit of the present utility model produces the powerful brake force being equal to service brake in very short time.
Description
Technical field:
This utility model 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 stress by some mechanisms
And producing brake force, its structure is complicated, and reliability is low.
Utility model content:
It is further added by a set of active safety system among this utility model 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, between them mutually independence, do not do mutually
Disturb, and the powerful brake force being equal to service brake can be produced.When safety pre-warning system perceives front relative velocity pair
When having barrier in the safe distance answered, start hydraulic oil cylinder type servo control mechanism immediately, promote the push rod of active safety brake pump
Produce brake force and reduce speed, until recovering again normal traveling after dangerous releasing.The technical solution of the utility model is as follows:
Vehicle safety brake unit, including parking braking pump, active safety brake pump, service brake pump, parking braking pump
Liquid outlet be connected to the inlet of active safety brake pump, the liquid outlet of active safety brake pump is connected to service brake pump
Inlet, 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 formula servo control mechanism oil circuit, hydraulic jack is connected to the push rod of active safety brake pump.
The beneficial effects of the utility model are: the hydraulic oil cylinder type servo control mechanism in this utility model can produce electronic etc.
Incomparable quickly the responding of servo control mechanism of other modes.And the active safety brake pump in this utility model 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 structure diagram of the present utility model, wherein 1: parking braking pump；2: active safety brake pump；3: driving system
Dynamic 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 utility model 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 is connected to active safety
The inlet of brake pump 2, the liquid outlet of active safety brake pump 2 is connected to the inlet of service brake pump 3, service brake pump 3
Liquid outlet be 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, normally open solenoid valve 9 structure
Becoming hydraulic oil cylinder type servo control mechanism oil circuit, hydraulic jack 7 is connected to the push rod 6 of active safety brake pump 2.
When the normally closed solenoid valve 8 in hydraulic oil cylinder type servo control mechanism oil circuit, normally open solenoid valve 9 obtain electric, oil cylinder 7 moment is made to fill
When pressure promotes the push rod 6 of active safety brake pump, this power will pass through the fluid pressure line of brakes and is delivered to four wheel systems
On the piston of dynamic wheel cylinder, thus on four wheels, create effect be equal to the powerful brake force of service brake.Work as electromagnetism
When valve 8, electromagnetic valve 9 dead electricity, oil cylinder pressure release, release braking.
