Specific embodiment
Please refer to shown in Fig. 1 to Fig. 5, of the invention without variable rigidity shock absorption supporting is rolled, it includes：Bottom basin 6, the bottom
Basin 6 has one towards upper opening, and inside has cuboid or tubular accommodation space, inside the accommodation space from
Under up accommodate rubber plate body 5, liner plate body 2, backing plate body 1, stainless steel plate body 4 and antifriction successively and be oriented to plate body 3, rubber slab
Body 5 is used for maintaining certain support strength and keeping preferable elastic performance.The structure composition of shock-absorbing bearing structure of the invention
Simply, low cost of manufacture.
Wherein, the lower surface of liner plate body 2 is connected with the upper surface of rubber plate body 5, the upper surface of liner plate body 5 and backing plate
The lower surface contact connection of body 1.Rubber plate body 5 is located at the inside bottom of bottom basin 6, on the upper surface of rubber plate body 5 or/and lower surface
Certain orientation respectively along surface is provided with multiple grooves 51, preferably, multiple grooves 51 can be interconnected, rubber plate body 5
In the case where the pressure that Train induced load is transmitted by track, backing plate body 1, liner plate body 5 is acted on, elastic deformation is produced, so as to reduce
Train induced load plays a part of vibration and noise reducing to the impulsive force of track；Preferably, groove 51 is evenly distributed on rubber plate body 5
Upper surface or/and lower surface on, specifically, groove 51 can in a ring be evenly distributed on upper surface or the following table of rubber plate body 5
Face.The groove 51 of the upper surface of rubber plate body 5 is staggered with the groove distributing position of the lower surface of rubber plate body 5, so that rubber
Plate body 5 has relatively large support strength and certain elastic performance.Rubber plate body 5 is by being located at its upper surface or lower surface
Groove 51, to reduce the actual contact bearing area of rubber plate body 5, while for the compression of rubber plate body 5 provides certain
Space, increases the elastic performance of rubber plate body 5, the present invention can further by adjusting the area accounting of different grooves 51, from
And the rubber plate body 5 of different elastic performances is obtained, and can be according to the need for specific, the area to the groove 51 of rubber plate body 5 is accounted for
Than the design for carrying out adaptability, the scope of application of rubber plate body 5 has been widened.It is of the invention acceptable individually in the upper of rubber plate body 5
Surface sets groove 51 or sets recessed simultaneously in the lower surface setting groove 51 of rubber plate body 5 or in upper and lower surface
Groove 51.Additionally, rubber plate body 5 of the invention is when by load impulsive force, because the deformation of rubber plate body 5 is non-linear change
Shape, its deformation rigidity increases with the increase of load, is conducive to reducing the change of the impact and control track to rubber plate body 5
Shape.
Wherein, when liner plate body 2 is manufactured using metal, it is metal liner plate body.Liner plate body 2 can will act at backing plate body 1
On load pass to rubber plate body 5, while liner plate body 2 is under the sidewise restraint of bottom basin, also act as the effect of vertically-guided, prevent
Only backing plate body 1 is rolled.The upper surface of liner plate body 2 sets fluted, and backing plate body 1 is placed in a groove, and the groove can play solid
Determine backing plate body 1, prevent the effect of the lateral sliding of backing plate body 1.Lateral groove, antifriction guide plate are provided with the side wall of liner plate body 2
Body 3 is embedded in lateral groove, and it is chimeric with liner plate body 2, and is fixedly connected with liner plate body 2.
Stainless steel plate body 4 is located at the side wall of bottom basin 6 and antifriction is oriented between plate body 3, the upper partial distance bottom of the side wall of bottom basin 6
Basin mouthful certain distance is provided with a step 61, and stainless steel plate body 4 is arranged on the step 61, and is fixedly connected with the side wall of bottom basin 6,
Preferably, used between stainless steel plate body 4 and the side wall of bottom basin 6 being welded to connect.Stainless steel plate body 4 is oriented to plate body 3 and connects with antifriction
Touch, antifriction is oriented between plate body 3 and stainless steel plate body 4 can only occur the relative slip of vertical direction, play hanging down to liner plate body 2
The straight effect for being oriented to and reducing friction.Meanwhile, antifriction is oriented to plate body 3 and is connected with the contact of stainless steel plate body 4, and stainless steel plate body 4 leads to
The side wall for crossing bottom basin 6 plays a part of lateral support to antifriction guiding plate body 3.
Backing plate body 1 is made up of nonmetallic materials, directly with the rail contact for being supported, when slowing down vehicle by track, and lotus
Carry to track impulsive force.When vehicle passes through track, when backing plate body 1 bears vehicle and passes through, the dynamic load of track is passed to, should
Dynamic load passes to rubber plate body 5 by liner plate body 2, and due to setting fluted on rubber plate body 5, rubber plate body 5 has very
Good variation rigidity elastic performance, so as to play vibration damping, noise reduction.
The inner bottom surface of bottom basin 6 is provided with air discharge duct 7, and air discharge duct 7 is connected with groove 51, exit and the external world of air discharge duct 7
UNICOM, when rubber plate body 5 is compressed, the air in the groove of rubber plate body 5 can be discharged along groove 51 and air discharge duct 7, be made
Rubber plate body 5 has preferably elasticity, and air can also be externally entering the groove 51 of rubber plate body 5 by air discharge duct 7
In, rubber plate body 5 is returned to initial support state.Preferably, air discharge duct 7 along the center of the bottom of bottom basin 6 to bottom basin 6
Side wall be arranged radially, air discharge duct 7 set quantity be at least 1.The polycrystalline substance of bottom basin 6 can be polygon, preferably
, bottom basin 6 is rectangle, and air discharge duct 7 can extend at polygonal angle along the center of bottom basin 6 or extend to polygon
Side at.When backing plate body 1 is acted on by load, the load that backing plate body 1 is subject to is delivered to rubber slab by liner plate body 2
During body 5, rubber plate body 5 produces compression under load action, and the air in the groove of rubber plate body 5 is discharged by air discharge duct 7, realizes
The compression of rubber plate body 5；After the load on rubber plate body 5 disappears, air can enter into rubber plate body by air discharge duct 7
In 5 groove so that rubber plate body 5 returns to initial holding state.
Used as enforceable mapping mode of the invention, the bottom of bottom basin of the invention 6 could be arranged to polygon or circle
Shape.Preferably, the bottom of bottom basin 6 is rectangle or circle, and when the bottom shape of bottom basin 6 is rectangle, rectangle bearing-surface
Greatly, preferably, bottom basin 6 has preferable stability to stability.It is circular easy to process when the bottom shape of bottom basin 6 is for circle, into
This low, low cost of bottom basin 6.
It is of the invention that without variable rigidity shock absorption supporting is rolled, the bottom of the bottom basin 6 of damping supporting is provided with rubber plate body 5, and
Groove 51 is provided with the upper and lower surface of rubber plate body 5, its elastic performance can be increased, reach optimal vibration damping effect
Really；Additionally, the relative closure of rubber plate body 5 internally space is made rubber by the liner plate body 2 and bottom basin 6 of damping supporting of the invention
Plate body 5 is avoided exposure in air, is corroded by ultraviolet direct irradiation and harsh weather, extends the use of rubber plate body 5
Life-span；Shock-absorbing bearing structure of the invention is simple, low cost.
Presently preferred embodiments of the present invention is these are only, this is not able to and is limited the protection domain that the present invention is implemented, therefore all ginsengs
Simple equivalence changes and modification that description of the invention is made are examined, still belongs to protection scope of the present invention.
