Abstract
The invention discloses a kind of Electronic Control parking braking system, belong to engineering machinery field.Which overcome vehicle normal work, complete machine power-off, again on can not realize effective brake under the operating mode such as electricity the defects of.Including brake switch, starting switch, braking electromagnetic valve, relay, power supply connects brake switch and relay respectively by starting switch, when starting switch gets to ON position, electrical equipment normally opened contact is in closure state, when starting switch gets to pass OFF, power supply is exported by contact gives relay coil anti-power supply source, and relay out-put supply is delivered on braking electromagnetic valve by starting switch, and then braking electromagnetic valve works.Present invention is mainly used for loading machine, can be used for other engineering machinery using planetary transmission.
Description
Technical field
The invention belongs to a kind of electric-control system, specifically, more particularly to a kind of loading machine electric control parking control for brake system
System.
Background technology
It is well known that loader body own wt is big, inertia is big.After parking, if being unable to effective brake, it may cause and slip
Phenomena such as car, consequence are extremely dangerous.
At present, loading machine parking braking system mainly has three kinds：
The first is tradition machinery parking braking mode.It is characterized in simple in construction, it is convenient to realize；But due to flexible axle
The performance of itself so that its braking moment is less than normal, and as use, torque can be less and less.
Second is gas braking parking braking mode.Be characterized in can effective guarantee braking moment, but complete machine for a long time
After parking, air pressure reduces, and brake force gradually reduces；Meanwhile it is easily aqueous in gas, accelerate failure.
The third is fluid braking parking braking mode.Which can effective guarantee braking moment, and shut down after stay
Car torque.If but exist and forget to press brake switch, the problem of complete machine is again after upper electricity, and parking braking is cancelled automatically, still deposit
In hidden danger.
The content of the invention
It is an object of the present invention to provide a kind of loading machine electric control parking braking control system, to overcome loading machine in the prior art
Brakes can not realize the defects of effective brake.
The present invention is realized using following technical scheme：
Described loading machine electric control parking braking control system, including brake switch, starting switch, braking electromagnetic valve, after
Electrical equipment, power supply connects brake switch and relay respectively by starting switch, when the starting switch gets to ON position, relay
Device coil obtains electric, and relay normally open contact is in closure state, and when starting switch, which is got to, closes OFF, power supply passes through contact
Exporting and give relay coil anti-power supply source, it is ensured that relay contact is maintained at on-state, and relay continues to output high level, after
Electrical equipment out-put supply is delivered on braking electromagnetic valve by starting switch, and then braking electromagnetic valve works.
Insurance is connected on the power takeoff leads.
The brake switch output end connects power cut indicator lamp.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is ensureing the feelings of original vehicle various aspects of performance
Under condition, effective parking braking after shutting down is realized, while no matter switchs and whether brakes after the upper electricity of realization, complete machine all keeps braking
State.The maloperation in work progress is reduced, avoids unnecessary injury.Meanwhile the invention is reduced using complexity such as controllers
Control device, design is very economical, reliable, and control effect is good, has reached North America parking braking safe design requirement, market competition
It is with the obvious advantage.
Brief description of the drawings
Fig. 1 is the electrical block diagram of the present invention；
In figure：1. brake switch；2. starting switch；3. insurance；4. power cut indicator lamp；5. braking electromagnetic valve；6. after
Electrical equipment.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, described loading machine electric control parking braking control system, including brake switch 1, starting switch 2, system
Moving electromagnetic valve 5, relay 6, power supply connect brake switch 1 and relay 6 respectively by starting switch 2, and starting switch 2 gets to ON
Position when, the coil of relay 6 obtains electric, and the contact adhesive of relay 6, the normally opened contact of relay 6 is in closure state, when startup is opened
When pass OFF is got in pass 2, power supply is exported by contact gives the coil of relay 6 anti-power supply source, it is ensured that the contact of relay 6 is kept
In on-state, relay 6 continues to output high level, and the out-put supply of relay 6 is delivered to braking electromagnetic valve by starting switch 2
On 5, braking electromagnetic valve 5 works.
Further, connection insurance 3 on power takeoff leads.
Further, the output end of brake switch 1 connection power cut indicator lamp 4.
Here is control for brake principle of the present invention under different operating modes：
Vehicle stopping brake：After complete machine parking, brake switch 1 is pressed, the coil of relay 6 obtains electric, the normally opened contact of relay 6
Must be electric, and contact closure；But because 6/8 pin of brake switch 1 is obstructed, cause the dead electricity of braking electromagnetic valve 5, complete machine parking system
It is dynamic；
Power-off brake：After complete machine power-off, complete machine dead electricity, the dead electricity of braking electromagnetic valve 5, complete machine parking braking is effective；
Upper electric braking：Complete machine powering, no matter now brake switch 1 is in unlatching or closed mode, braking electromagnetic valve 5 are equal
It can not obtain electric, therefore complete machine parking braking is still effective.
Release braking：After complete machine powering, brake switch 1 is first pressed, now 24V power supplys are given to the coil of relay 6 and output
End, it is ensured that the normally opened contact of relay 6 is in closure state；Brake switch 1 is closed again, now switchs the connection of 6/8 pin, and
Now, the coil of relay 6 has electricity all the time so that the normally opened contact of relay 6 closes all the time, it is ensured that and braking electromagnetic valve 5 must be electric, so as to
Parking braking is unlocked, complete machine enters vehicle traveling and working condition.
