Abstract
The utility model provides a rubber composite overturning bearing for fixing a truck cab rear suspension. The rubber composite overturning bearing is provided with a metal framework outer sleeve and a metal framework inner sleeve, and a composite elastic body is arranged between the metal framework outer sleeve and the metal framework inner sleeve. The surface of the outer circumference of the metal framework outer sleeve is evenly provided with an arc protrusion in the axial direction, arc grooves are evenly formed in the inner surface of the metal framework outer sleeve in the axial direction, and the number of the arc grooves is larger than that of the arc protrusion. According to the rubber composite overturning bearing for fixing the truck cab rear suspension, the structure is simple, the performance cost ratio is high, assembling is convenient, the rubber material of the elastic body is high in stretching and compressing strength and good in elastic resilience, the wear resistance, the ageing resistance and the damping and buffering performance are greatly improved, the service life is greatly prolonged, meanwhile the driving safety and the overall performance of a truck are improved, and the operation cost for an enterprise and a user is greatly reduced.
Description
Technical field
The utility model belongs to autotruck accessory manufacturing technology field, is specifically related to a kind of rubber combined upset bearing for fixed load automobile cab rear suspension.
Background technology
Upset bearing is for fixing cab rear suspension, play buffering, the effect of damping and stressed transmission, the stationarity that truck is travelled, safety and maintain and replace convenience play significant role, it is bogie I class fragile part, mostly be caoutchous or ironware for truck cab's upset bearing in the market, in vehicle traveling process, impulsive force directly passes to upset bearing by cab rear suspension, the stressed ambassador's rubber deformation badly broken excessively of impulsive force transmittance process centre bearer or metal lining do not have shock-absorbing function, cause thus truck cab's upset bearing damage rate high especially, safety is low, after-sales service work capacity is large, enterprise and user's operation cost are high, therefore be necessary to propose to improve.
Utility model content
The technical matters that the utility model solves: a kind of rubber combined upset bearing for fixed load automobile cab rear suspension is provided, metallic framework overcoat, metallic framework inner sleeve and composite elastic body sulfidization molding are integrated, in use realize cab rear suspension system bearing, damping and buffer action, improved the service life of automobile cab rear-suspension system.
The technical solution adopted in the utility model: for the rubber combined upset bearing of fixed load automobile cab rear suspension, there is metallic framework overcoat and metallic framework inner sleeve, between described metallic framework overcoat and metallic framework inner sleeve, be provided with composite elastic body, wherein, described metallic framework overcoat external peripheral surface is laid with arc convex vertically, and the metallic framework overcoat inside face vertically uniform quantity that is shaped with arc groove and arc groove is greater than the quantity of arc convex.
Wherein, the integral structure that described arc convex and arc groove and metallic framework overcoat are formed in one.
Further, described metallic framework overcoat external peripheral surface is laid with 8 arc convex vertically, and metallic framework overcoat inside face is uniform is vertically shaped with 13 arc grooves.
Further, described metallic framework inner sleeve end is provided with chamfering.
Further, described metallic framework overcoat, metallic framework inner sleeve and composite elastic body three sulfidization molding are integrated.
The utility model is compared with prior art simple in structure, cost performance is high, easy to assembly, elastomer rubber material extending compression strength is high, rebound resilience is good, and resistance to abrasion, resistance to ag(e)ing and damping, buffering performance significantly improve, and significantly improve service life, improve heavy duty truck driving safety and overall performance simultaneously, significantly reduced enterprise and user's operation cost.

Detailed description of the invention
Below in conjunction with accompanying drawing 1-3, a kind of embodiment of the present utility model is described.
For the rubber combined upset bearing of fixed load automobile cab rear suspension, there is metallic framework overcoat 1 and metallic framework inner sleeve 2, between described metallic framework overcoat 1 and metallic framework inner sleeve 2, be provided with composite elastic body 3, wherein, described metallic framework overcoat 1 external peripheral surface is laid with arc convex 4 vertically, the metallic framework overcoat 1 inside face vertically uniform quantity that is shaped with arc groove 5 and arc groove 5 is greater than the quantity of arc convex 4, concrete, metallic framework overcoat 1 inside face is uniform is vertically shaped with 13 arc grooves 5, the integral structure that described arc convex 4 and arc groove 5 and metallic framework overcoat 1 are formed in one, described metallic framework overcoat 1 external peripheral surface is laid with 8 arc convex 4 vertically, described metallic framework inner sleeve 2 ends are provided with chamfering 6, described metallic framework overcoat 1, metallic framework inner sleeve 2 and composite elastic body 3 three's sulfidization moldings are integrated.
Metallic framework overcoat 1, metallic framework inner sleeve 2 and composite elastic body 3 three's sulfidization moldings are integrated the rubber combined upset bearing of composition, when use, by cab rear suspension set casing, rubber combined upset bearing is fixed, thereby realize cab rear suspension system bearing, damping, buffer action, metallic framework overcoat 1 external peripheral surface is laid with 8 arc convex 4 vertically, can improve the firm degree after assembling, metallic framework overcoat 1 inside face is uniform is vertically shaped with 13 arc grooves 5, improve the reliability that metallic framework overcoat 1 is connected with composite elastic body 3, not fragile in the time being subject to external force, elastic composite body 3 is neoprene simultaneously, neoprene ageing-resistant performance is high, wear resisting property is good, increased substantially the service life of rubber combined upset bearing, therefore truck cab's rear-suspension system after sale guarantee time has obtained prolongation, greatly improve the service life of automobile cab rear-suspension system, reduce car production producer and user's use cost.
Above-described embodiment, is preferred embodiment of the present utility model, is not used for limiting the utility model practical range, and the equivalence of being done with content described in the utility model claim therefore all changes, within all should being included in the utility model claim scope.
