The elastomer tension and compression transformation bidirectional buffer has simple structure, so that the manufacture, examination and maintenance costs are preferable compared with other buffers.

Description

Elastic body tension and compression conversion two-way function energy disperser
Technical field
The utility model relates to a kind of guideway vehicle shock attenuation device, the energy disperser that especially a kind of city railway vehicle and passenger train bidirectional buffering are used.
Background technology
Energy disperser is one of vehicle vitals, plays the effect that relaxes longitudinal impulse when transmitting the train travelling process longitudinal force.
In world's trolley coach vehicle scope, the kind of energy disperser is a lot, divides according to the buffer buffers media type, mainly comprises the combined buffers of steel spring formula energy disperser, water bumper, rubber draft gear and above type buffer etc.Long, low cost of manufacture of steel spring formula energy disperser life-span in the three class energy dispersers, but weight is bigger; Simple in structure, the low cost of manufacture of rubber draft gear, but the rubber life-span is shorter; Water bumper function admirable, but complex structure, cost is higher and the life-span is shorter.Although and the combined buffers function admirable, general complex structure is made, the cost of overhaul is higher.
In addition, existing guideway vehicle energy disperser also exists other deficiency, less as energy disperser according to the series of products of performance segmentation, the problem that the initial stiffness of ubiquity energy disperser is bigger seldom has and satisfies that municipal rail train marshalling is little, to start the braking speed change frequent and cushion characteristic is good, the energy disperser of good economy performance.
Summary of the invention
This practical purpose is the deficiency at existing energy disperser existence, and a kind of novel tension and compression conversion two-way function energy disperser that adopts elastomeric spring to cushion is provided.
Technical solution of the present utility model is: a kind of elastic body tension and compression conversion two-way function energy disperser, and comprise the housing of an end opening, and be installed in draw bar in the housing from opening part, be set with elastomeric spring and inhibiting device on the draw bar.
Preferably, described draw bar is provided with a plurality of elastomeric springs, is provided with intermediate hsg between the adjacent elastomeric spring.
Preferably, described inhibiting device comprises spacing pad, dividing plate, base, the nut that is sleeved on successively on the draw bar, and the middle go side lid that is installed in the shell nozzle inner edge, and elastomeric spring is between spacing pad and base.
Preferably, spacing pad, nut and draw bar screw thread are affixed, and end cap is fixed on the housing by screw thread.
Preferably, described middle go side lid is provided with two-stage Ka Tai, respectively with dividing plate and spacing pad slip clamping.
Preferably, the outer rim of described base and dividing plate all is equipped with the guiding semi-ring.
The beneficial effects of the utility model are: can be by changing the quantity of one group of elastomeric spring, realize that within the specific limits different marshallings require the requirement of train to energy disperser, promptly can realize multiple demand to draft gear travel, capacity and rigidity, because this novel elastomer tension and compression conversion two-way function buffer structure is simple, therefore manufacturing and repair and maintenance cost have remarkable advantages than other energy dispersers.
Description of drawings
Fig. 1 is the sectional structure scheme drawing of the utility model specific embodiment;
Structural representation when Fig. 2 is the installation, traction of the utility model specific embodiment and compressive state.
The specific embodiment
Specific embodiment of the utility model as shown in Figure 1, a kind of elastic body tension and compression conversion two-way function energy disperser, the housing 10 that comprises an end opening, and be installed in draw bar 1 in the housing 10 from opening part, be set with elastomeric spring 5 and inhibiting device on the draw bar 1.Described draw bar 1 is provided with a plurality of elastomeric springs 5, is provided with intermediate hsg 6 between the adjacent elastomeric spring 5.Described inhibiting device comprises spacing pad 3, dividing plate 4, base 9, the nut 8 that is sleeved on successively on the draw bar 1, and the middle go side lid 2 that is installed in housing 10 opening inner edges, elastomeric spring 5 is between spacing pad 3 and base 9, spacing pad 3, nut 8 and draw bar 1 screw thread are affixed, and end cap 2 is fixed on the housing 10 by screw thread.Go side lid 2 is provided with two-stage Ka Tai in described, respectively with dividing plate 4 and the 3 slip clampings of spacing pad.The outer rim of described base 9 and dividing plate 4 all is equipped with guiding semi-ring 7.
As shown in Figure 2, during work, housing 10 1 ends are fixed, and when draw bar 1 is stretched and power is delivered on the base 9, base 9 is to the motion of tensile force direction, and elastomeric spring 5 is compressed power.When spacing pad 3 moved to end cap 2, the elastomeric-type energy disperser reached the maximum tension stroke.When tensile load surpassed range load, one group of elastomeric spring 5 was subjected to overload protection.
During power, draw bar 1 pressurized contracts power is delivered on spacing pad 3, the dividing plate 4 successively by compression, and elastomeric spring 5 is compressed power.When the moving to housing and form 10 bottom of draw bar 1 and thin nut 8, the elastomeric-type energy disperser reaches the maximum compression stroke.When clamp load surpassed range load, elastomeric spring 5 was subjected to overload protection.
In the whole process that stretching, compression and the tension and compression of energy disperser are changed, elastomeric spring passes through distortion absorption portion impact energy, thereby plays the impact energy effect between buffering and the absorption vehicle.
