Description
Technical field
The present invention relates to guideway vehicle technical field, relate in particular to a kind of rubber draft gear and buffer cell thereof of coupler and draft gear.
Background technology
Coupler and draft gear is for connection, transmitting tractive power, braking force between the each compartment of train and relaxes the parts of longitudinal impact force, in coupler and draft gear, be provided with energy disperser, the type of energy disperser comprises dish-type energy disperser, spring friction draft gear, rubber draft gear and water bumper etc., the advantages such as wherein simple in structure owing to having, easy to maintenance, the cheap and buffering effect of rubber draft gear is outstanding, thereby it has obtained application more and more widely.
Resistance refers to that coupler draft gear acts on the power of hitch or car body, and stroke refers to the compressed amount of coupler draft gear, along with macro-axis is heavy and heavily loaded special line train open-minded, the performance requriements of energy disperser has been proposed to more and more higher endergonic requirement.Under normal circumstances, energy disperser all has rated impedance power and rated travel requirement, the condition that energy disperser can be brought into play its maximum energy-absorbing effect is that whole compression process resistance is large as far as possible, and in the time reaching the rated travel of energy disperser, resistance also just reaches rated impedance power.
Current rubber draft gear is made up of the stacked multiple buffer cells that are serially connected, wherein buffer cell is respectively to vulcanize one deck rubber on the two sides of steel plate, and in current rubber draft gear, the cross section of rubber is trapezoidal, trapezoidal large end and the laminating of the surface of steel plate, in when assembling to pre compressed magnitude of buffer cell, after assembling completes, in each buffer cell, the small end of rubber is in contact with one another.In use, along with the increase of load, the area of contact in the process of distortion of the rubber in buffer cell is increasing, thereby the rigidity of product also will be increasing.
Predetermincd tension appropriateness when guaranteeing to install, the initial stiffness of current rubber draft gear is less than normal, thereby in the compression starting stage, the increase of its resistance increases because rigidity is less than normal slowly, and because each buffer cell has applied certain precompressed amount in the time assembling, sulfuration has produced certain strain at the rubber on steel plate two sides, along with the increase of amount of compression, the strain of the rubber layer of each buffer cell has reached the limit soon, thereby rigidity sharply increases, resistance has has also just met and exceeded rapidly rated value in very short stroke, and now buffer stroke also reaches far away rated value, this has just caused the absorbent energy of rubber draft gear institute less, cannot meet macro-axis weighs and the requirement of heavily loaded special line train to energy disperser.
Therefore, how can improve rubber draft gear is the technical matters that current those skilled in the art need solution badly to the absorption power of energy.
Summary of the invention
One of object of the present invention is to provide a kind of buffer cell of rubber draft gear, so that can improve the absorption power of current rubber draft gear to energy.
Another object of the present invention is also to provide a kind of energy disperser that comprises above-mentioned buffer cell.
For solving above-mentioned prior art problem, the buffer cell of rubber draft gear provided by the invention comprises middle part stay bearing plate and vulcanizes the bottom rubber layer in stay bearing plate both sides, described middle part, the described bottom rubber layer of both sides is symmetrical arranged about described middle part stay bearing plate, and on the described bottom rubber layer of every side, be provided with can be concordant with described bottom rubber layer under the effect of predetermincd tension rubber bumps.
Preferably, in above-mentioned buffer cell, on the described bottom rubber layer of every side, be provided with multiple described rubber bumps, and multiple described rubber bumps scattering device is on the rubber layer of described bottom.
Preferably, in above-mentioned buffer cell, described middle part stay bearing plate is steel plate.
