Description
Technical field
The invention belongs to technical field of rail traffic, in particular to a kind of city rail vehicle rescues brake control method.
Background technique
For low-floor tramcar or railcar, when certain train breaks down, need to utilize relief car pair
Disabled vehicle is rescued, and rescue mode includes two kinds, and one is relief cars to push 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 active of passive spring braking (being braked including level-one spring braking, two-level spring), trailer of electric braking, motor-car including motor-car
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 issue service braking, emergency braking, safety arrestment or individually issue magnetic rail braking order.Meanwhile it can
Safety arrestment order is issued in disabled vehicle safe operation stop button, or operation magnetic rail braking button issues magnetic rail braking life
It enables.
And in the prior art, no matter relief car pushes or pulls on disabled vehicle rescue, the rescue brake control method taken are as follows: 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 condition, (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 hangs together phase so as to cause train
The stressed member (including car body, hitch, run-through channel, articulated mounting, warping resistance device etc.) of pass generates biggish deformation or displacement,
Biggish damage is generated to stressed member, influences the service life of train, increases operation cost.
Summary of the invention
In existing rescue brake control method, in different rescue operating conditions, (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 hangs together relevant stressed member (packet so as to cause train
Include car body, hitch, run-through channel, articulated mounting, warping resistance device etc.) biggish deformation or displacement are generated, stressed member is generated
Biggish damage influences the service life of train, increases operation cost.It is an object of the present invention to be directed to 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
Brake force is provided, meanwhile, the brake force size that relief car and disabled vehicle apply rationally is controlled, to a variety of of relief car and disabled vehicle
Mode of braking carries out linkage control, can reduce train and hangs together deformation or displacement that relevant stressed member is generated in rescue,
Reduce the damage to related stressed member is hung together, extends the service life of train, cut operating costs.
In order to solve the above technical problems, the technical scheme adopted by the invention is that:
A kind of city rail vehicle rescue brake control method, its main feature is that relief car and disabled vehicle apply brake force simultaneously,
The brake force that middle relief car applies is greater than or equal to the brake force that disabled vehicle applies.
When train rescuing traction, relevant stressed member (including car body, hitch, run-through channel, hinged dress are hung together on vehicle
Set, warping resistance device etc.) compression or drawing force can be born, and then lead to deformation or displacement.Because low floor vehicle braking itself subtracts
Speed is bigger, during rescue, if the deceleration that two trains are generated by 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 is reduced train and is hung together the generation in rescue of relevant stressed member
Deformation or displacement, and then reduce damage to related stressed member is hung together.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 pushes away from but regardless of rescue operating condition for relief car
Disabled vehicle or relief car draw disabled vehicle, and in braking process, the deformation for hanging together related stressed member remains stationary or in the presence of subtracting
Small trend can protect and hang together related stressed member, reduces stress damage, extends the service life of train, reduce operation at
This.
