Abstract
An improved compression load ball joint assembly is comprised of a metal housing having an open end and an internal cylindrical cavity at least partially receiving a portion of a movable bearing member, a lower metal bearing, an upper metal split bearing and a belleville washer. The upper metal split bearing is disposed opposite the lower metal bearing to simultaneously mate with the movable bearing member and the housing. The upper metal split bearing is configured to be slidable within the housing to provide a stable wear surface against the movable bearing member. The lower metal bearing, the upper metal split bearing, the Belleville spring washer and the movable bearing element are all covered in the housing by a cover plate which is arranged around the movable bearing element and fixed at the opening end of the housing.
Description
Technical field
The present invention relates to the spherojoint bearing; The full-metallic compressive load spherojoint that particularly relates to improvement; This full-metallic compressive load spherojoint adopts the subdivision upper bearing (metal); It is configured as the top of ball stud and the shape that sidepiece provides bearing surface, and allows this bearing to cooperate fully with housing and this bolt simultaneously.
Background technique
Be used for to be divided into two kinds like conventional ball joint or other active base of motor turning and suspension.First kind is used for driven member and tension load occasion, and wherein the bolt part of spherojoint bears axial tension load, and second kind be used for the compressive load occasion, and wherein the bolt part of spherojoint bears axial compression loading.Because the thrust load that bolt part bore under these two kinds of occasions is different,, generally be not interchangeable so required spherojoint is also different.
Usually, ball-and-socket joint comprises cylindrical shell, and this cylindrical shell is provided with the opening that internal surface of column and bolt part bar portion are passed.The ball-shaped end of this bolt part is located in the housing, is supported in this housing by one or more bearing members.Traditionally, this bearing member is processed by synthetic resin, for example polymer or elastomer, perhaps sintered alloy.These elements are installed in the housing via an opening, and ball stud extends through an axial opening that is provided with, and this opening can be the above-mentioned opening that installation elements passes, and also can be an axial opening opposing.Usually; The tension load spherojoint; For example take the M2 technology chassis part of the not lattice chassis part branch (Moog Chassis Parts division) of moral sieve one Mo Geer company (FederalMogul Corporation), adopt two openings being located at housing two opposite ends.After being installed on element in the housing, through with a cover plate spinning, forge or be welded on and be fit to the position with a closure of openings, bolt part stretches out from another opposed openings.In a single day cover plate is installed in suitable position, just directly or through an elastic caoutchouc intermediary element is pressed in indirectly on these bearing members.
By contrast, compressive load spherojoint housing for example shown in the 6th, 010, No. 271 U. S. Patents of Jackson et a1. application, only has a single opening.In the installation process, all elements are all installed through this opening, and bolt part also stretches out through this opening.These elements comprise pressure spring, polymer lower bearing, bolt part and metal upper bearing (metal).In case these elements are positioned at suitable position, bolt part bar portion is outstanding from opening, just makes the periphery inclination of this opening or crimping be fit to position and pressure spring so that element remains in.
In case assembled, spherojoint and active base can be used as bearing carrier in many mechanical systems, comprise the vehicle suspension and the steering system of automobile.The active base or the ball bearing that are used for these occasions work under the various operation conditionss, and possibly need to carry actual load.Along with continuous wearing and tearing, the particularly continuous wearing and tearing of polymer bearing, the performance of active base or spherojoint reduces rapidly, and this can cause the erratic steering of vehicle suspension system or cross pine and activity in automotive applications.
Therefore, a kind of compressive load ball-and-socket joint that improves wear resistance need be provided.
Summary of the invention
Brief description, the present invention provides a kind of compressive load spherojoint device of improvement, and this device is made up of metal shell, and this housing is provided with the opening end and the interior cylindrical cavity of receiver portion live bearing spare at least in part.Following metal bearing is packaged in it in cylindrical cavity by said housing, and cooperates with said live bearing spare.This lower bearing spare is fixed through the inner surface of its outer surface and said housing and the interference fit between the end face, does not produce displacement.Last metal split bearing is packaged in the said interior cylindrical cavity by said housing, and is coaxial with said live bearing spare.Upward metal split bearing and said metal bearing down are oppositely arranged, to cooperate simultaneously with said live bearing and said housing.Last metal split bearing is configured to the shape that can in said housing, slide, so that the stable wear surface near said live bearing spare to be provided.Belleville washers and said live bearing spare are provided with around this live bearing spare coaxially, to provide a thrust load on the subdivision upper bearing (metal).This lower bearing, last split bearing, belleville washers and live bearing spare are covered in the said housing by a cover plate, and this cover plate centers on the setting of live bearing spare and is fixed in the opening end of housing.
Of the present invention above-mentioned and other purposes, feature and advantage and the present invention are current for ease of understanding
