Description
Technical field
The invention belongs to technical field of rail traffic, more particularly to a kind of city rail vehicle rescue brake control method.
Background technology
For low-floor tramcar or railcar, when certain train breaks down, it is necessary to utilize relief car pair
Disabled vehicle is rescued, and rescue mode includes two kinds, and one kind is that relief car pushes away disabled vehicle, and another kind is that relief car draws disabled vehicle.
The braking mode of low floor vehicle includes service braking, emergency braking, safety arrestment.Low floor vehicle mode of braking
The passive spring braking (being braked including level-one spring braking, two-level spring) of electric braking, motor-car including motor-car, the active of trailer
Hydraulic braking, magnetic rail braking.
It when relief car rescues disabled vehicle, is if desired braked, is generally operated in relief car, such as operate driver's control
Device handle or button processed send service braking, emergency braking, safety arrestment or individually send magnetic rail braking order.It meanwhile can
Safety arrestment order is sent in disabled vehicle safe operation stop button or operation magnetic rail braking button sends magnetic rail braking life
Order.
And in the prior art, no matter relief car pushes or pulls on disabled vehicle rescue, and the rescue brake control method taken is：One
As in the case of, relief car and disabled vehicle carry out control for brake by relief car and provide brake force, i.e. relief car and disabled vehicle
Brake force is only provided by relief car.In emergency, the mushroom button that stops in emergency is operated in relief car or disabled vehicle, realizes two
Train applies the emergency brake simultaneously.In existing rescue brake control method, in different rescue operating mode, (relief car is given a pretext barrier
Vehicle, relief car draw disabled vehicle) under, the brake force size of relief car and disabled vehicle is randomly assigned, and phase is hung together so as to cause train
The stressed member (including car body, hitch, run-through channel, articulated mounting, warping resistance device etc.) of pass generates larger deformation or displacement,
Larger damage is generated to stressed member, influences the service life of train, increases operation cost.
The content of the invention
In existing rescue brake control method, in different rescue operating modes, (relief car pushes away disabled vehicle, relief car draws failure
Vehicle) under, the brake force size of relief car and disabled vehicle is randomly assigned, and relevant stressed member (bag is hung together so as to cause train
Include car body, hitch, run-through channel, articulated mounting, warping resistance device etc.) larger deformation or displacement are generated, stressed member is generated
Larger damage influences the service life of train, increases operation cost.It is an object of the present invention to for the above-mentioned prior art
Deficiency, provide it is a kind of improve city rail vehicle rescue brake control method, in train rescuing, relief car and disabled vehicle are equal

When train rescuing is drawn, relevant stressed member is hung together on vehicle (including car body, hitch, run-through channel, hinged dress
Put, warping resistance device etc.) compression or drawing force can be born, and then cause deformation or displacement.It brakes and subtracts in itself because of low floor vehicle
Speed is bigger, during rescue, if the deceleration that two trains generate due to braking is identical, what related stressed member generated
Deformation or displacement will remain unchanged.If deceleration is different, deformation or displacement may reduce, it is also possible to increase.Therefore, it is necessary to right
The brake force size of relief car and disabled vehicle is rationally controlled, and reduction train hangs together relevant stressed member and generated in rescue
Deformation or displacement, and then reduce the damage to hanging together related stressed member.By the method for the invention, due to control for brake
When, the brake force that relief car applies is greater than or equal to the brake force that disabled vehicle applies, and is pushed away from but regardless of rescue operating mode for relief car
Disabled vehicle or relief car draw disabled vehicle, and in braking process, the deformation for hanging together related stressed member is remained stationary or in the presence of subtracting
Small trend can be protected and hang together related stressed member, reduce stress damage, extend the service life of train, reduce operation into
This.
