Description
What the present invention relates to is the coupler system in rail compartment, is used for the energy disperser of this system more precisely.In this energy disperser, use insert, so that when energy disperser absorbs and slow down impulsive force on the coupler system, regulate friction drag.
Existing rail compartment coupler system generally all has energy disperser, is used for absorbing and slows down impulsive force in this system, to stop to this system and to the mechanical damage in this rail compartment.
The energy disperser of early stage rail compartment coupler system, the existing description in US Patent 1982575.It comprises one in front and one in back two driven members, they engage with the hitch and the yoke of coupler system respectively, before Slave Block be installed in the position that the housing that can force energy disperser moves backward, the action of back Slave Block promotes one group of drift, and the motion of drift is subjected to coming from the friction drag of the spring assembly of friction plate and compression.The spring leaf that these drifts are close to by some and friction plate is every putting.
Recent energy disperser is described in US Patent 3348633.It has a drift that moves inward under the external force effect that imposes on coupler system, this drift and one group of friction shoe mutual action, said friction shoe is positioned on one group of friction tilting fillet that is mated, the restriction of friction force between the compression elasticity that the moving inward of drift and friction shoe is subjected to elasticity weakening sheet and friction shoe and watt seat.
Have in each friction tilting fillet a pair of groove be used for placing metal lubrication spare with adjust watt and watt seat between friction coefficient.Metal lubrication spare is an insert that places groove, is placed on when it begins between tile fragment and watt seat, beats drift with a weight then, metal is inserted in the groove, and outwards moves between the surface of tile fragment and friction tilting fillet.
In the energy disperser of rail of the present invention compartment coupler system, comprise a hollow casting box,, a spring plate group of being made up of plurality of elastic weakening sheet usually is installed in the inner end wall of casing and between the * piece.Slave Block extend in the rubbing hole section, constitutes a friction tilting fillet group.In each friction tilting fillet, a friction tile fragment is arranged, these tile fragments drift outer with reaching rubbing hole fits.
Each friction tilting fillet all has a groove, and this groove is made up of with water jacket and the link slot parallel with the casing longitudinal axis the vertical inside groove of a pair of and the casing longitudinal axis.The one rigid metal insert similar to the shape of groove arranged in each groove, and the attaching parts of this insert is between friction shoe and the friction seat, and one deck lubricating film is provided.
When coupler system and energy disperser work thereof, sizable impulsive force bears in system, and these power pass to energy disperser, and energy disperser then can absorb and relax these power, in case locking system and institute's bonded assembly railway carriage suffer mechanical damage.
These power are ordered about drift and are moved to the inside, oppress then and move in the friction shoe and radially outwards extruding, the inside mobile restriction that is subjected to the compression elasticity of friction force between friction shoe and watt seat and spring leaf.
Energy disperser of the present invention is compared with existing energy disperser has following characteristics:
At first, can more effectively regulate the friction drag of friction tilting fillet to the tile fragment motion.Improvement to this adjusting makes the life-span of tile fragment be increased, and has prevented that tile fragment is by locked.If self-locking has taken place tile fragment when energy disperser is in compressive state, then tile fragment and spring can not turn back to the position when not being compressed, and can not make coupler system avoid the mechanical damage that subsequent impacts power is caused so effectively.Improvement to adjusting is to realize by becoming flexible of insert in the groove that is limited in casing.In existing energy disperser, the amount that moves inward when tile fragment is very big so that can not cover insert in the water jacket time, it is loosening this kind promptly can to occur.Because the insert of energy disperser of the present invention is a rigidity, simultaneously,,, only can stay in the water jacket so the insert in the water jacket can not become flexible because the remainder of insert is always covered by tile fragment.Like this, the continuous conformability of tile fragment action just is guaranteed.
Secondly, the energy disperser of this novel practical also has a big advantage, that is: the casing of device is to adopt the modern times, and the foundry engieering that can be mass-produced makes.The hollow lumen of casing is to formalize by the core in the mold, and this core makes in a moulding box, this moulding box has several portions, form a parting line in conjunction with the back, the link slot of this parting line and casing rubbing hole groove aligns, open the hole of an expansion on other link slot, then the each several part of moulding box can trip out from a complete core upper edge right angle orientation.

One group of assembling energy disperser that is used for rail compartment coupler system as shown in Figure 4, this device is with label 10 expressions.Known as those skilled in the art, device 10 is installed in usually on the yoke and (does not mark among the figure), and this yoke links to each other with the bottom girder (not marking) of rail compartment envelope (not marking) again.
The casing 12 of energy disperser 10 is shown specifically in accompanying drawing 1,2 and 3, the inner segment 14 of casing 12 is surrounded jointly by roof 16, (two) placed apart sidewall 18 and an end part 20, casing 12 is a foundry goods, stays several lightening holes, for example: the opening 22 on each sidewall 18.This opening can trip out core when also making casting easily.In addition, casing inner segment 14 also has end wall 24 to form a closed inner chamber 26.
What link to each other with casing inner segment 14 is external friction hole section 28.Rubbing hole section 28 is to be surrounded by the sidewall 30 of arranging by hexagon.Each intersects the fillet 38 that is 120 ° between the inside surface of side wall 32,34 and 36 of closing on mutually, as shown in Figure 3, and to form a friction-top watt seat 40 and two side friction tilting fillets 42.These friction tilting fillets 40,42 have constituted rubbing hole section inner chamber 46.
One top H connected in star 48 is arranged in friction-top watt seat, and as shown in Figure 6, top groove is made up of inside groove 50, water jacket 52 and the link slot 54 that connects them.The cross sectional shape of the link slot 54 of top groove as shown in Figure 7, the cross sectional shape of groove 50,52 and it are basic identical.
Each side friction tilting fillet 42 also has a H connected in star, is made up of inside groove 58, water jacket 60 and the link slot 62 that is connected them equally.As shown in Figure 8, the lower wall 64 of link slot 62 is level basically, upper wall 66 then approximately relatively horizontal surface be 30 ° of angles, lower wall 64 and upper wall 66 this arranged and made the opening of link slot 62 of each side groove 56 enlarge.
The position that is noted that link slot 54,62 aligns with fillet 38, so just makes the axis normal of each inside groove 50,52 and each water jacket 58,60 and casing 14, link slot 54,62 then with this parallel axes.Through such location, promptly between three retaining edge 70 that separate and on the position near retaining edge thickness inboard, these keep off edge 70 on the limit of rubbing hole section wall 72 to groove 48,56, and advance the inner chamber 46 of rubbing hole section to convex.
Be embedded with lubricated insert 76 in top groove 48 and side groove 56, it is made by bronze material.Insert 76 has been made detailed description in accompanying drawing 9-12, it has a pair of being parallel to each other, meniscate camber member 78, and each camber member 78 usefulness middle transition arc section 80 connects the flat segments 82 at two ends.Camber member 78 is interconnected by a connection piece 84 near their mid point.The inside face 86 of part 78,84 basically with the inside face 32,34,36 of rubbing hole section and knuckle 38 coplanes of sidewall 30.The lateral surface of part 78,84 is the lucky arc surface that matches with top and side groove 48,56.The cross sectional shape of attaching parts 84 as shown in Figure 12.The cross sectional shape of camber member 78 is similar to it.
As previously mentioned, Fig. 4 is the energy disperser 10 that assembles, in the inner chamber 26 of casing 12, end wall 24 and one movably in the middle of between the Slave Block 94, a spring plate group of being made up of plurality of elastic weakening sheet 92 is housed.The outer end 96 of Slave Block 94 extend in the casing rubbing hole inner chamber 46 and fits with the inwall 98 of three friction shoes 100.
Each friction shoe 100 has the friction face 102 of a pair of taper, see Fig. 5, these friction faces 102 engage with arc surface 104, each friction shoe 100 is loaded on respectively on top and the side friction tilting fillet 40,42, and surface 32,34 and 36 contacts within the side of the friction face 102 of friction shoe and rubbing hole like this.Friction face 102 is contacted with the inner surface plane 86 of insert 78, and the circular arc end face 104 of friction shoe 100 then correspondingly is positioned in the fillet 38, thereby contacts with the attaching parts 84 of insert 76.
Each also has oblique inwall 106 in to friction shoe 100, and the inwall 106 of these friction shoes 100 is inclination wedge surface 108 wedgings surplus, on a drift 110 mutually with one with its inclination angle again.Drift 110 outer ends 112 reach outside the limit wall 72 of casing rubbing hole section 28.The outer end 112 of drift device 110 mainly contacts with the Slave Block (not marking among the figure) of coupler system, and this Slave Block engages with the inner of hitch, and its outer end coupling head then is used for connecting the coupler head in other rail compartment.
The front underdrawed, and draft gear housing 14 is made by casting.The outer surface profile of core is corresponding with the inner surface profile of casing 14, and core is put into mold, and the inner surface profile of mold is corresponding with the outer surface profile of casing.The core of casing is made in moulding box, and the inner surface profile of the moulding box inner surface profile with casing 14 basically is identical.So moulding box is made top and the side groove shape profile similar to the top of casing 14 and side groove 48,56 too.In order to use the foundry technique that can produce in enormous quantities, the parting line that forms between the moulding box each several part should align with the link slot of the top groove of core.After core is shaped since between the enlarging upper wall of the link slot of side groove and the lower wall at an angle, make the moulding box each several part can be easily from the core that has been shaped approximately the direction along the right angle trip out.
In operational process, the coupler system power that withstands shocks, these power may be inwards, i.e. cushion effect.Also may be outside, i.e. tractive force.When articulating two joint compartments, as surpassing 5 meters/hour, bump between the coupler head of hitch separately when speed, this moment, coupler system bore cushion effect.When the rail compartment from dead position by to front haulage the time, coupler system then is subjected to tractive force.
In order to prevent that these impulsive forces from causing the mechanical damage of the other parts in coupler system and rail compartment, use energy disperser 10 to absorb and relax these impulsive forces.For example: when being subjected to cushion effect, the drift 110 of energy disperser 10 just is pushed to the inboard, and the inclined-plane 108 of drift 110 forces friction shoe 100 inwards and radially outside again, extruding.And the sidewall 30 of the friction tilting fillet 40,42 of rubbing hole is conflicted mutually with the friction face 102 of friction shoe, has limited the footpath of voussoir 110 and has outwards moved.Moving in the friction shoe 100 at first is the constraint that is subjected to the friction face 102 and the friction force between the friction tilting fillet 40,42 of friction shoe, the product of the size of this constrained force to be friction coefficient between two surfaces and drift 110 impose on perpendicular to the tile fragment sense of motion power of friction shoe 100.In addition, watt in move the elasticity weakening sheet 92 that also is subjected to coming from spring plate group constraint, this spring plate group this moment just since watts 100 promote in the middle of Slave Blocks 94 move to the end wall 24 of casing and be in compressive state.
Be noted that friction shoe 100 can move inward fully, make the arc insert 78 of water jacket 52,60 parts come out.The attaching parts 84 of insert and all the other parallel camber member parts 78 of being positioned at inside groove 50,58 are still kept in touch with watts 100.Because insert 76 is rigidity, is retained in the water jacket 52,60 so guaranteed the camber member 78 of expose portion.
When friction shoe moves, watt friction face 102 also with inner plane 86 mutual actions of insert 76.Watt friction face 102 on be coated with the last layer film identical with the insert material, with watts 100 and friction tilting fillet 40,42 between set up a lubricated interface, this lubricant has been regulated friction coefficient, make it remain on a value more uniformly, thereby prolonged for watts 100 service life, promoted the smooth operation of tile fragment.Friction shoe 100 not only inwardly moves and overcomes uniform friction force, and, in case after impulsive force was absorbed, its just outwards moved and touch retaining edge 70 so that drift 110 resets.If elasticity weakening sheet 92, watts 100 and drift 110 do not reset like this, just then energy disperser can not absorb follow-up impulsive force effectively, the mechanical damage of coupler system may take place again.
If the friction face 102 of friction shoe 100 has damaged, then watt 100 meeting footpaths outwards be moved, this fillet part 104 that just forces watt is pressed on the fillet 38 of cooresponding friction tilting fillet with it more tightly, as long as the tight ness rating of this contact increases, the possibility of watt pinning will increase.But the fillet part 104 that is noted that watt can offset with the attaching parts 84 of insert, does not align as friction shoe, and then the attaching parts 84 of insert will provide an one deck lubricating film and a soft district between them, stops watt locked.Like this, elasticity weakening sheet 92, friction shoe 100 and drift 110 will can not be stuck when being in inside pressure position.
Embodiments of the present invention have been made diagram and have been described, but should see also that simultaneously the present invention is not limited in the scope of claim defined, concerning the professional and technical personnel, also can do various modifications or variation, but these do not exceed scope of the present invention and thought.
