The bushing comprising an inner sleeve, an outer sleeve, filling rubber layers and retaining rings. The outer surface of the inner sleeve is in an arc shape protruded outwardly on the axial section of a bushing body, the inner surface of the outer sleeve is in an arc shape protruded inwardly on the axial section of the bushing body, a high damping alloy layer is arranged between the inner sleeve and the outer sleeve, and the filling rubber layers fill between the inner sleeve and the high damping alloy layer and between the outer sleeve and the high damping alloy layer; the inner sleeve is in a hollow cylindrical structure with two ends with steps, the diameters of two ends are smaller than the diameter of the middle of the inner sleeve, and two ends of the inner sleeve are provided with the retaining rings respectively through the steps of the inner sleeve. Owing to the unique shapes of the inner sleeve and outer sleeve, the radial strength of the leaf spring bushing is increased; the high damping alloy layer is arranged between the inner sleeve and the outer sleeve, the axial strength of the filling rubber layers is increased, and the fine damping performance is provided.
Description
Technical field
The present invention relates to a kind of automotive suspension elastic element, refer more particularly to a kind of leaf springs of car lining.
Background technology
Leaf springs of car is elastic element the most traditional in automobile suspension system, due to its good reliability, simple in structure, manufacturing process flow is short, cost is low and structure such as can simplify greatly at the advantage, thereby is widely used.Leaf springs of car is generally by some not isometric alloy spring steels, to combine one group to be similar to equal strength spring beam.
Leaf spring lining is bogie fragile part, is arranged in flat spring bracket assembly and leaf spring grasswort, plays the effect of buffering, damping and stressed transmission, and the traveling comfort travelling, stationarity, safety and maintain and replace convenience are played to significant role.On Vehicles Collected from Market for bogie leaf spring lining, structure is single, directly with steel pipe, process, be embedded in leaf spring grasswort or flat spring bracket assembly, in load-carrying vehicle driving process, impulsive force is directly delivered to plate spring assembly by flat spring bracket, in impulsive force transmittance process, there is no shock absorption device, impact process is also 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 complete vehicle quality simultaneously, has increased enterprise operation cost, and after-sales service work capacity is rolled up, and has restricted to a certain extent the development of enterprise.
Through retrieval, China Patent No.: ZL 201320751800.8, Granted publication day: on April 30th, 2014, denomination of invention is: a kind of leaf springs of car lining of good springiness, include interior steel bushing and outer steel sleeve, outer upper end and the lower end of described interior steel bushing have circular groove, in circular groove, be provided with back-up ring, described outer steel sleeve is positioned at the outside of steel bushing, between interior steel bushing and outer steel sleeve, be provided with double-deck corrugated surface elastic skeleton, between double-deck corrugated surface elastic skeleton, be provided with a plurality of springs, between double-deck corrugated surface elastic skeleton and interior steel bushing and outer steel sleeve, be respectively equipped with elastic rubbery body, at the outer wall of interior steel bushing and the inwall of outer steel sleeve, be respectively equipped with a plurality of boss, it is inner that described boss stretches into described elastic rubbery body.In this application case, between double-deck corrugated surface elastic skeleton, be provided with a plurality of springs, good damping effect, still, due to the existence of its spring, causes the axial strength of leaf spring lining to weaken, and easily causes the radial dimension of lining excessive, is not easy to use.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of leaf springs of car lining, solve the damping, buffering poor performance of leaf spring lining in prior art, noise is large, 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, has the problem of torsional deflection and retardance phenomenon.
For solving the problems of the technologies described above, the technical scheme providing of the present invention is:
A kind of leaf springs of car lining of the present invention, comprise inner sleeve, overcoat, filled rubber layer and back-up ring, wherein, the outside face of described inner sleeve is outside outstanding arc on lining axial cross section, the inside face of overcoat is inside outstanding arc on lining axial cross section, in the middle of described inner sleeve and overcoat, be provided with high damping alloy layer, described filled rubber layer is filled between inner sleeve and high damping alloy layer and between overcoat and high damping alloy layer, described inner sleeve is the hollow cylinder structure of two ends band ladder, its two ends diameter is less than inner sleeve middle part diameter, described inner sleeve two ends are respectively arranged with back-up ring, be enclosed within on the ladder of inner sleeve.
Further, described filled rubber layer and inner sleeve, overcoat and high damping alloy layer are sulfided into one.
Further, described back-up ring is axially three-decker along it, and outer two layers is rubber layer, and internal layer is high damping alloy interlayer, and three-decker is sulfided into one.
Further, described high damping alloy layer is copper-Zn-Al alloy layer or manganese-copper alloy layer.
Further, described high damping alloy layer is corrugated tube shape.
Adopt technical scheme provided by the invention, compare with existing known technology, there is following beneficial effect:
(1) a kind of leaf springs of car lining of the present invention, because the outside face of inner sleeve is outside outstanding arc on lining axial cross section, the inside face of overcoat is inside outstanding arc on lining axial cross section, such special construction limited filled rubber layer between inner sleeve and overcoat along the axial activity of lining, both increase the axial strength of lining, also increased the radial strength of lining.
(2) a kind of leaf springs of car lining of the present invention, is provided with the high damping alloy layer of corrugated tube shape between inner sleeve and overcoat, both can increase filled rubber layer axially and radial strength, can also guarantee good damping performance.
(3) a kind of leaf springs of car lining of the present invention, its back-up ring is axially three-decker along it, and outer two layers is rubber layer, and internal layer is high damping alloy interlayer, and back-up ring intensity is high, and good damping effect.
(4) a kind of leaf springs of car lining of the present invention, simple in structure, is easy to manufacture low production cost.
