Abstract
Disclosed is a rubber buffer composed of a seat bang, a header rubber stack, a middle rubber stack, an end rubber stack and a bottom plate. The utility model adapts to railway freight cars with less than 3000T traction tonnage and a light total weight, in particular to meter-gauge freight cars. The buffer is characterized by high capacity, excellent stability, reliable application, durability, stiffness and a geometric shape of the rubber stack overcoming the disadvantages of incompressibility and large linear expansion coefficient. The buffer has a simple structure, an easy manufacturing, a convenient maintenance, a light weight and a low cost.
Description
One, technical field
Energy disperser is one of vitals of rail vehicles.Energy disperser, hitch make locomotive and vehicle, or realize to connect hang between vehicle and the vehicle, and the bump and the vibrations that reduce and transmit that train is in operation or cause at impulsive force that shunting service produced or fierce tractive force.
Two, background technology
Now use goods train buffer, mainly be applicable to the above railway truck of traction large-tonnage 3000T, but for the traction railway truck that tonnage is little, lade weight of a vehicle is also little, especially meter gage railway vehicle, at present the buffer capacity, the resistance that use of railroad train is all too big, easily causes longitudinal impact force between vehicle excessive and reduce the vehicle operation life-span.
ZL 02276616.2 rubber vehicle energy disperser, elastic element---rubber metal pad is contained in the vertical rectangle frame, and the defective of three aspects is arranged: 1. vertical rectangle frame, steel consumption is still bigger; 2. the hitch guide plate stretches out the upper end of rectangle frame, is actually with the hitch flush fit to connect together, and repair demolition is very inconvenient; 3. sheet rubber heap body only has two boss, and the centre has only a groove, and elastic element is subjected to external impacts compressing rubber heap heap body transverse expansion, and the space that can hold lateral expansion is too little, will certainly influence effective performance of its function.
Three, summary of the invention
Technical solutions of the utility model are the defectives at ZL 02276616.2 vehicle bumper, design is connected seat board and base plate by seat board with the bolt location and installation hole of cooresponding position, base plate diagonal angle by two Luo bars, assemble elastic element between seat board and the base plate---mutually chimericly be the rubber metal pad of one, formation rubber draft gear.
The utility model, seat board and base plate are the steel Casting Partss; Two rubber metal pads of initial and end are one with two steel plate sulfurations respectively, and a slice relies on clamping plate to be connected with seat board, and a slice is connected with base plate by clamping plate; The every group of rubber metal pad in middle part is to be one by two heap bodies with a clamping plate sulfuration, totally seven groups, be embedded as a whole mutually again, and become intermediate rubber and pile; Intermediate rubber heap two ends are embedded as a whole with the initial and end rubber metal pad respectively, load onto bolt at seat board and base plate diagonal position bolt location and installation hole then, nut is put at bolt two, so far seat board stem rubber metal pad, intermediate rubber heap, afterbody rubber metal pad, base plate is connected to become rubber draft gear.
Rubber metal pad is an elastic element.Rubber in the rubber metal pad is the special (purpose) rubber of manufacturing energy disperser, compare with General Purpose Rubber, this rubber proves that by experiment modulus of elasticity is little, have religion high capacity and good stable, reliability of applying, durability have been guaranteed the rigidity of energy disperser again, in addition, rubber metal pad design-calculated geometric configuration has overcome the rubber incompressibility as much as possible and has had the defective of big linear expansion factor.Rubber metal pad is simple in structure, manufactures easily, and is in light weight, low cost.
Seat board, design has bolt location and installation hole to be connected with bed bolt location and installation hole by bolt nut, elastic element---head and the tail rubber metal pad, middle part rubber metal pad folder provide powerful bearing area for one to elastic element.This seat board one side contacts with slave plate before the hitch, and another side contacts with the stem of elastic element, by seat board the compressive force from the automatic car coupler coupler body is passed to energy disperser, perhaps the tensile force of energy disperser is passed to under-carriage through preceding slave plate.
Base plate is provided with bolt location and installation hole, and decide mounting hole by bolt nut with the seat board bolt and be connected, elastic element---the rubber metal pad folder provides powerful bearing area for one to elastic element.This base plate one side contact with slave plate behind the hitch, and another side contacts with the afterbody of elastic element, passes to energy disperser by the base plate handle from the tensile force of automatic car coupler coupler body, perhaps the Compression and Expansion power of energy disperser through after slave plate pass to under-carriage.
Install the two ends of bolt on seat board and the base plate, its extended position screw rod stretches out up and down and leaves enough clearance envelopes, and the aperture in bolt location and installation hole is slightly larger than the screw diameter of bolt again; When compressive force from the automatic car coupler coupler body, give elastic element through buffer transfer, rubber metal pad is compressed, perhaps from the tensile force of automatic car coupler coupler body, pass to elastic element through buffering, rubber metal pad is stretched, and this moment, bolt location and installation hole can be free to slide along screw rod; Chat as preceding institute, when rubber metal pad was compressed under external force, rubber metal pad boss meeting lateral expansion because of groove is arranged between the boss, can be free to slide along screw rod because of bolt location and installation hole again, so be unlikely to influence the normal operation of this energy disperser.
The utility model: seat board, base plate connect to form rack-like structures by two Luo bars, and simple than framed structure, steel consumption is few, and cost is low, and repair demolition is very convenient, and change part is easy, can not consume more man-hour; Meanwhile rubber metal pad heap body is provided with three boss, the centre is the rectangle platform, both sides are the hexagon platform, form two grooves between three boss, rubber metal pad is subjected to external impacts, compression, and heap body lateral expansion has and holds the enough spaces of lateral expansion, thereby can not influence the normal operation of energy disperser, to realize purpose of the present invention.
