Abstract
The utility model relates to a plate spring lining and belongs to the technical field of automobile spare parts manufacturing. The plate spring lining is characterized in that a metallic framework is arranged outside a central spindle and is sequentially provided with an inner sleeve and an outer sleeve, two ends of the central spindle are provided with an upper check ring and a lower check ring, elastomer materials are arranged between the central spindle and the inner sleeve, the inner sleeve and the outer sleeve, and the upper check ring and the lower check ring in a compound mode, the central spindle is of a cylinder with steps structure, the inner sleeve is provided with holes along the side wall of the inner sleeve, and the outer sleeve is provided with cutting edge chamfers. The plate spring lining is simple in structure, low in cost, capable of prolonging service life dramatically, easy to assemble and maintain, capable of enhancing shock-absorbing buffer performance sharply, and at the same time, high in driving stability and security, and capable of being widely applied to a lorry plate spring system.
Description
One, technical field
The utility model relates to a kind of rubber shock-absorbing buffer structure spare for vehicle plate spring assembly and flat spring bracket assembly use, and specifically a kind of leaf spring lining belongs to vehicular spare parts manufacturing technology field.
Two, background technology
The leaf spring lining is bogie I class fragile part, is installed in flat spring bracket assembly and the leaf spring grasswort, plays the effect of buffering, damping and stressed transmission, and traveling comfort, stationarity, safety and the maintain and replace convenience that travels played significant role.Be used for bogie leaf spring lining on the Vehicles Collected from Market, structure is single, directly process with steel pipe, be embedded in leaf spring grasswort or the flat spring bracket assembly, impulsive force directly is delivered to plate spring assembly by flat spring bracket in the load-carrying vehicle driving process, do not have shock absorption device in the impulsive force transmittance process, impact process also is endergonic process, and load-carrying vehicle leaf spring system failure rate is always high.Existing leaf spring lining is short service life, has not only increased user's operation cost, has reduced simultaneously complete vehicle quality, has increased the enterprise operation cost, and the after-sales service work capacity is rolled up, and has restricted to a certain extent the development of enterprise.
Three, utility model content
The utility model mainly is to adopt old-fashioned all-metal skeleton structure in order to solve existing bogie leaf spring lining, the damping, buffering poor performance, service life is short, assembling and maintain and replace work capacity are large, the motion of leaf spring components of system as directed is steady not, smooth and easy, torsional deflection and retardance phenomenon are arranged, thus a kind of new technical scheme that proposes.
For achieving the above object, the utility model can be realized by following scheme:
A kind of leaf spring lining, it is by elastic body and the metallic framework assembly is compound consists of, metallic framework is to be provided with successively inner sleeve and overcoat outside mandrel, be equipped with back-up ring and lower back-up ring at the mandrel two ends, between mandrel and the inner sleeve, between inner sleeve and the overcoat and and the cavity of upper back-up ring and lower back-up ring between the compound elastic body that is provided with; Described mandrel is the cylinder hollow structure, and the mandrel two ends are cylindrical band ledge structures; Described sidewall of the inside race is provided with the hole, and overcoat one end is provided with the cutting edge chamfering; Described upper back-up ring and lower back-up ring are the tubular type structure.
Inner sleeve and overcoat are tube-shaped structures, and the side is provided with opening.
The advantage that the utility model compared with prior art has is: simple in structure, easy to use, cheap for manufacturing cost, elastomeric material Compression and Expansion intensity is high, rebound resilience is good, and resistance to abrasion, resistance to ag(e)ing and damping, buffering performance significantly improve, and the leaf spring system is significantly improved service life.Improve simultaneously driving comfort and safety, reduced user's operation cost, reduced to a great extent vehicle after-sales service work capacity, improved the autotruck overall performance.
Four, description of drawings
Accompanying drawing 1 is a kind of example structure schematic diagram of the utility model;
Accompanying drawing 2 is inner sleeve 2 structural representations in the utility model accompanying drawing 1;
Accompanying drawing 3 is overcoat 3 structural representations in the utility model accompanying drawing 1;
Accompanying drawing 4 is upper back-up ring 4 and lower back-up ring 5 structural representations in the utility model accompanying drawing 1.
Among the figure: 1, mandrel, 2, inner sleeve, 3, overcoat, 4, upper back-up ring, 5, lower back-up ring, 6, elastic body.
Five, the specific embodiment
With specific embodiment the utility model is described in further details by reference to the accompanying drawings now:
A kind of leaf spring lining, it is by elastic body and metallic framework is compound consists of, metallic framework is comprised of mandrel 1, inner sleeve 2, overcoat 3, upper back-up ring 4, lower back-up ring 5, its structure is to be provided with successively inner sleeve 2 and overcoat 3 outside mandrel 1, be equipped with back-up ring 4 and lower back-up ring 5 at mandrel 1 two ends, between mandrel 1 and the inner sleeve 2, between inner sleeve 2 and the overcoat 3 and and the cavity of upper back-up ring 4 and lower back-up ring 5 between the compound elastic body 6 that is provided with, mandrel 1 two ends are cylindrical band ledge structures, and the step at the up and down two ends of mandrel 1 is respectively fitted with back-up ring 4 and lower back-up ring 5.Described mandrel 1 is the cylinder hollow structure, and described inner sleeve 2 sidewalls are provided with many groups hole, can guarantee that elastic body 6 is compound more tight and firm with inner sleeve 2, and overcoat 3 is provided with the cutting edge chamfering, and inner sleeve 2 and overcoat 3 are nonocclusive tube-shaped structures, and the side is provided with opening; Upper back-up ring 4 and lower back-up ring 5 are the tubular type structure.
Principle of work is:
The rubber shock-absorbing buffer structure spare that is used for autotruck leaf spring system, to be the mandrel 1 in the metallic framework, inner sleeve 2, overcoat 3, upper back-up ring 4, lower back-up ring 5 and elastic body 6 that elastomeric material is combined with each other, by compression machine the leaf spring lining is pressed in leaf spring grasswort and the flat spring bracket hole, overcoat 3 is closely supporting with leaf spring grasswort or flat spring bracket hole wall, by bolt and connecting panel flat spring bracket assembly and leaf spring are linked together, thereby realize leaf spring system bearing, damping, buffer action.Leaf spring lining and the old-fashioned steel bushing apparatus with shock absorbing of comparing, the damping, buffering better effects if.Inner sleeve 2 is provided with hole, tartan passes from hole mandrel 1, inner sleeve 2 and overcoat 3 is better linked together, the neoprene ageing-resistant performance is high simultaneously, wear resisting property is good, be 12～18 months service life, therefore autotruck after sale guarantee time has extended to more than 1 year, has greatly improved the service life of leaf spring system in the bogie.Reduced autotruck manufacturer and user's use cost.
