Description
Technical field
The utility model relates to a kind of rail dampener of urban track traffic, in particular to a kind of offset rail dampener, there is the track section of vibration and noise reducing requirement for various subway and urban light rail, connect rail and railway roadbed, and effective separating vibration and minimizing noise.
Background technology
Along with science and technology constantly progress, urban track traffic is rapidly developed.The speed of subway reaches, safety, comfort features are more and more higher to track damping noise reduction, safety, requirement that the is stable and life-span.In order to alleviate urban traffic pressure, small curvature radius circuit has been applied in urban track traffic, and small curvature radius line requirements Damping fastening system has higher lateral stiffness.When train is by small curvature radius track, its lateral force and twisting resistance increase more obvious, and shock absorber is stressed more complicated.Because some offset rail dampener is asymmetric structure, the top board boss namely retraining rail is that asymmetric is arranged.Elastic body is to the top board constraint also constraint in asymmetric.Train applies vertical force, lateral force and twisting resistance by rail to rail dampener, makes rail dampener rubber deformation complicated, and shock absorber base sheet stresses is too concentrated and caused overall lateral stiffness not enough, and vibration damper fatigue life is seriously restricted.
Utility model content
The utility model is too concentrated for the offset rail dampener stress of asymmetric structure in prior art and is caused overall lateral stiffness not enough, make the technical problem that vibration damper fatigue life is seriously restricted, a kind of offset rail dampener is provided, there is high transverse stiffness, improve the fatigue life of shock absorber, meet the damping requirements of small curvature radius route.
For achieving the above object, the technical solution adopted in the utility model is: offset rail dampener, comprise top board, base plate and the elastic body between top board and base plate, top board, base plate and elastomer link into an integrated entity, the upper surface mid portion of top board is the support rail face of carrying rails, diagonally opposing corner position, bearing surface both sides respectively establishes one for the constraint boss of fixing rail, two diagonal angles of base plate have the fixing hole for fixed bias formula rail dampener, fixed hole position is outside constraint platform, it is characterized in that elastomeric lateral surface and contacts baseplate, elastomeric medial surface and top plate contact also extend to the bottom of top board, described base plate is provided with the horizontal plate washer raised up near at least one fixing hole, described elastic body has the lateral projection elastic body corresponding with horizontal plate washer, described lateral projection elastic body is sandwiched between horizontal plate washer and top board.
Further, horizontal plate washer is equipped with near two fixing holes of described base plate.
Further, the length of the side length that described top board contacts with lateral projection elastic body and described horizontal plate washer and the elastomeric identical length of lateral projection together, make described elastic body encase top board.
Further, described top board is identical with the elastomeric height of lateral projection with the side that lateral projection elastic body contacts.
Further, the height of described horizontal plate washer is slightly lower than the elastomeric height of described lateral projection.
The beneficial effects of the utility model are: the utility model increases horizontal plate washer and the lateral projection elastic body corresponding with horizontal plate washer near base plate fixing hole, lateral projection elastic body is sandwiched between horizontal plate washer and top board, make the side of top board also to have rubber constraint, the lateral force pushed away suffered by base plate is divided by horizontal plate washer, make the rail be contained on the bearing surface of top board, by top board, lateral force is evenly delivered to base plate, base sheet stresses is avoided to concentrate, increase the overall lateral stiffness of shock absorber, improve the fatigue life of shock absorber, meet the damping requirements of small curvature radius route.
