The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.Should be understood that, the specific embodiment described herein only is used for description and interpretation the utility model, is not limited to the utility model.
as shown in Figure 1, the utility model discloses a kind of coupler draft gear, this coupler draft gear comprises the first baffle plate 1, assembled shaft 2, dividing plate 3, elastic cushion block 4 and second baffle 5, the first baffle plate 1 and second baffle 5 interconnect and are set in spaced reciprocally on assembled shaft 2, the two ends of this assembled shaft 2 are formed with respectively for the first baffle plate 1 and second baffle 5 are carried out axially outwards spacing positive stop lug boss 21, dividing plate 3 and elastic cushion block 4 are a plurality of, these a plurality of dividing plates 3 and elastic cushion block 4 along assembled shaft 2 axially alternately be set on assembled shaft 2 and between the first baffle plate 1 and second baffle 5.In coupler draft gear of the present utility model, with bear external tensile force and thrust two baffle intervals be arranged on assembled shaft 2, positive stop lug boss 21 is set axially outside spacing so that baffle plate is carried out on assembled shaft 2, limit two damper shaft to outside movement (namely both mutually away from), and can only be close to each other be dividing plate 3 and elastic cushion block 4 with the elastomer group in the middle of pushing, thereby form the one-level vibration reducing mode.Wherein, elastomer group is made of a plurality of dividing plates 3 and elastic cushion block 4 alternative arrangement, forms a plurality of damper units, and pressure-bearing is stressed more even, and vibration damping stability and buffering effect are better.
In coupler draft gear of the present utility model, for increasing the comprehensive cushioning performance of energy disperser, elastic cushion block 4 is preferably thermoplastic polyester elastomer (TPEE) cushion block.The rated impedance Li Keda 2500kN of TPEE material, properties is better than the General Purpose Rubber material, and has higher capacity.Its shock resistance is good, and temperature applicable range is wide, and stable performance, reliable can be born larger Tensile or Compressive Loading.The ageing resistance of the energy disperser of employing Polymer TPEE is good, because High molecular material TPEE has higher ageing resistance than elastomeric material, and TPEE will be well below the sensivity of rubber to temperature to the sensivity of temperature, and namely the Polymer TPEE material as padded coaming has stable buffering, cushioning performance than elastomeric material.With the rubber phase ratio, the TPEE energy disperser has better processing characteristics and longer service life.Compare with material of construction, have equally the high characteristics of intensity, and elasticity and dynamic mechanical better.TPEE has and flexible like rubber phase, elasticity and mechanical strength, but its resistance to effect of heat and weather resisting property are better than rubber.Therefore, the coupler draft gear of use TPEE material is functional and stable.
In the present embodiment, coupler draft gear can be based on interior electric car hook mounting interface, and the entire length of energy disperser is 569mm.Wherein, elastic cushion block 4 should be no less than 8, and the thickness of each elastic cushion block 4 is not less than 20mm, and dividing plate 3 is preferably doughnut-shaped steel plate, can adopt the Q345 material, and thickness is not less than 10mm.Like this, two dividing plates 3 consist of the single elastomer unit with stronger cushioning performance with the middle elastic cushion block that clamps 4.And whole elastomer group has 8 elastomer units, and total length reaches 309mm, and the capacity of whole energy disperser is provided, and absorbs from the impact energy between two locomotives or locomotive and vehicle, damped vibration.
Wherein, assembled shaft 2 can adopt the forging of 40Cr material to form, and can play to elastomer group the effect of being located by connecting in whole coupler draft gear.Two baffle plates can adopt the casting of C level steel to form.Be simplified design and manufacturing process, the baffle plate that is arranged on elastomer group two ends can adopt identical parts.In addition, preferably be connected by a plurality of tie bolts 6 between the first baffle plate 1 and second baffle 5, the first baffle plate 1 and second baffle 5 can be close to each other along the axial direction of tie bolt 6.Connect by a plurality of tie bolts 6 between two baffle plates, as the installation basis of whole coupler draft gear.Tie bolt 6 should have enough strength and stiffness, to guarantee that whole energy disperser is bear can trouble free service under larger tension and compression load.Tie bolt 6 plays the connection fastening effect in whole energy disperser, have simultaneously the longitudinal spacing effect concurrently, is not damaged with the protection elastomer group.Spacing collar 7 between the first baffle plate 1 and second baffle 5 also can be installed on tie bolt 6, and the supercompression of elastomer group between these spacing collar 7 restriction two side shield centerings is in order to avoid elastomer group is impaired.When under external force, the spacing between two baffle plates is decreased to the length of spacing collar 7, when namely two side blocks are resisted against respectively on the both ends of the surface of spacing collar 7, can stop external force to the further compression of elastomer group.More preferably, spacing collar 7 can be set on tie bolt 6 with moving axially, to adapt to two baffle plates different displacements separately under different stressing conditions, make spacing collar 7 except limit between two baffle plates excessively near other stressed and movement of not defining baffle.
Coupler draft gear in present embodiment adopts the one-level vibration reducing mode, i.e. power-absorbing when traction and braking is the elastomer group of middle part.Concrete, with reference to Fig. 1, when traction, tractive force is applied in the following order successively by tail frame afterbody: baffle plate 5 → compresses elastomeric group → baffle plate 1 → coupler pocket.When braking, braking force is applied in the following order successively: baffle plate 1 → compresses elastomeric group → baffle plate 5 → coupler pocket.In two processes of traction and braking, elastomer group all reaches the purpose of energy-obsorbing and damping by compression.Wherein, by adopting Polymer TPEE material as the energy-obsorbing and damping material, solve the problem of the poor-performing of energy disperser, made energy disperser have functional and stable cushion characteristic.And this coupler draft gear is simple in structure, can satisfy the requirement of high-power freight locomotive traction, deceleration and stopping performance.
Below describe by reference to the accompanying drawings preferred implementation of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; in technical conceive scope of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
Need to prove in addition, each concrete technical characterictic described in the above-mentioned specific embodiment in reconcilable situation, can make up by any suitable mode, for fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible array modes.
In addition, also can carry out combination in any between various embodiment of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
