Abstract
A V-shaped spring damping limiter comprises a locomotive wheelset axle box, combined V-shaped springs and a bogie, wherein the combined V-shaped springs are symmetrically arranged on two sides of the locomotive wheelset axle box, and the bogie is arranged on the peripheries of the combined V-shaped springs. The V-shaped spring damping limiter is characterized in that a combined limiting block consisting of an outside metal rigidity limiting unit and an inside rubber elastic limiting unit is arranged in the middle of the upper portion of the locomotive wheelset axle box, a compressing deformation space of rubber elastic materials is reserved between the metal rigidity limiting unit and the rubber elastic limiting unit, and the metal rigidity limiting unit and the rubber elastic limiting unit inside are fixedly connected in series by the aid of a bolt on a rubber elastic limiting block. Irregular displacement of the bogie along the perpendicular direction is limited, falling distance of relative systems on the springs is controlled within a safety range so as to prevent an integral system from being faulted caused by damage of the relative systems on the springs, simultaneously, falling distance of the bogie is restrained within a safety range by the V-shaped spring damping limiter, and a locomotive can return safely. Further, the V-shaped spring damping limiter is novel in structure and reliable in running.
Description
Technical field
The utility model relates to a kind of metal-rubber combined V shape spring shock absorption inhibiting device that is applied to the mine locomotive vehicle hanging.
Background technology
Metal-rubber combined V shape spring is the single stage suspension system that is mainly used in the mine locomotive vehicle, can right tractive force and the braking force of transfer machine wheel, give bogie truck with resilient mounting in vertical direction, provide at the vertical and horizontal of train to flexibly connect and spacing effect; The generation of application force, reduce and the disappearance process in, bogie truck is under the elastomeric material elastic reaction, geometric configuration is recovered to initial condition, thereby guarantee that member tends to an equilibrium state all the time, elastomeric material better elastic and suitable damping are able to play a role in this process, realization to vibration, impact slow down and absorb, thereby realize desired effectiveness in vibration suppression.But because vertical load increase suddenly causes load to exceed the design load-carrying capacity of rubber spring on the bogie truck; Or the dynamic compression fatigue that peel off at the adhesion of rubber to metal place and spring is suffered causes rubber spring to lose efficacy, so that the excessive increase of bogie truck vertical deviation, causes on the spring related system to fall and causes the failure.
The utility model content
The purpose of this utility model is to provide a kind of V-arrangement spring shock absorption inhibiting device.In the displacement of vertical direction mal, avoid related system damage on the spring with the restriction bogie truck, guarantee that the safety of locomotive is returned, and it is convenient to change the V-type rubber spring.
The technical solution of the utility model is: comprise locomotive wheel to axle box, be symmetricly set on the compound V shape spring of locomotive wheel to the axle box both sides; Be located at the bogie truck of compound V shape spring periphery; It is characterized in that, be provided with spacing and the spacing combination limiting stopper of forming of the caoutchouc elasticity the inside at locomotive wheel to the upper center of axle box, leave the compressive deformation space of rubber elastic material between described metal rigidity the caoutchouc elasticity spacing and the inside is spacing by the metal rigidity of outside; The two is fixing by the series connection of the bolt on the caoutchouc elasticity limiting stopper.
Described elasticity is spacing and the spacing distance apart from the axle box upper end of rigidity is definite according to the vertical stiffness of rubber spring.
During work, normally in service at locomotive, vertical impact load is arranged on bogie truck, the V-type rubber spring gives bogie truck with resilient mounting in vertical direction, when the bogie truck vertical deviation exceeds rubber spring design-calculated standard operation stroke, support for bogie truck by the elasticity limiting stopper with assistant spring in vertical direction, guarantee the bogie truck vertical deviation at particular range, the dynamic compression of avoiding rubber spring is tired and lost efficacy ahead of time; When peel off or during the fatigue failure of rubber spring dynamic compression at the adhesion of rubber to metal place of rubber spring, and the spacing assistant spring of elasticity supports the weight that can't carry bogie truck, then by the weight of the spacing carrying bogie truck of rigidity, the vertical whereabouts of restriction bogie truck, the related system distance of fall is in safe range on the control spring, avoid the damage of related system, guarantee that motorcycle safety returns to change the V-type rubber spring.
The utility model can limit bogie truck at vertical direction mal displacement, the related system distance of fall is in safe range on the control spring, avoid related system damage on the spring, and cause total system to be paralysed, the bogie truck distance of fall of realizing the constraint of V-type rubber spring shock absorption device guarantees that in safe range the safety of locomotive is returned.Its novel structure, reliable operation.

The specific embodiment
The utility model is described in further detail below in conjunction with embodiment.
Embodiment 1:
Comprise locomotive wheel to axle box 3, be symmetricly set on the compound V shape spring 1 of locomotive wheel to the axle box both sides; Be located at the bogie truck 4 of compound V shape spring periphery; At locomotive wheel the upper center of axle box 3 is provided with the combination limiting stopper of being made up of rigidity spacing 9 and elasticity spacing 8; The combination limiting stopper of present embodiment is cylindrical, and the metallic cylinder of outside is that rigidity is spacing, and it is that elasticity is spacing that elastomeric material is housed in metallic cylinder.And metal rigidity is spacing and the caoutchouc elasticity of the inside leaves the compressive deformation space of elastomeric material between spacing; The two is fixing by 10 series connection of the bolt on the caoutchouc elasticity limiting stopper.
After being installed to V-type rubber spring 1 on the bogie truck 4 during use, end plate 5,6 is diverted frame 4 and axle box 3 fitting surfaces constraint location respectively, can transfer wheel to 7 tractive force and braking force, give bogie truck with resilient mounting in vertical direction, provide for the vertical and horizontal of locomotive and flexibly connect and spacing effect; The generation of normal forces, reduce and the disappearance process in, member is under the elastomeric material elastic reaction, geometric configuration is recovered to initial condition, thereby guarantees that member tends to an equilibrium state all the time, and elastomeric material better elastic and suitable damping are able to play a role in this process.When locomotive normally in service, vertical load increases suddenly on bogie truck 4, when bogie truck 4 vertical deviations float increase greatly in normal range, be located at the elasticity spacing 8 in the combination limiting stopper 2 of axle box 3 tops, support for bogie truck 4 with assistant spring in vertical direction, to reduce rubber spring dynamic compression fatigue; When peel off or suffered dynamic compression fatigue failure at the adhesion of rubber to metal place of rubber spring, the rubber spring forfeiture continues to bear the ability of original design load and the assistant spring of elasticity spacing 8 supports in the time of can't satisfying, spacing 9 carrying bogie truck and the car body weight of rigidity in the combination limiting stopper 2, the related system distance of fall is in safe range on the control spring, avoid the damage of related system, preventing that total system from damaging suddenly, and cause unpredictable serious consequence.Present embodiment is mainly used in the single stage suspension system of rolling stock applicable to various metals-rubber combined V shape spring.
