Abstract
The utility model discloses a flexible ball joint assembly bushing for controlling a heavy truck, which comprises an upper bushing part and a bushing bottom, wherein a first inner cavity with an upward opening is arranged in the upper bushing part; the bushing bottom is provided with a second inner cavity with a downward opening; a partition is arranged between the first inner cavity and the second inner cavity; the bottom surface of the bushing bottom is inwardly dished; and the bottom surface of the bushing bottom is an inwardly-dished cambered surface. The contact area of the bottom surface of the bushing and the metal washer is reduced, thereby effectively reducing the mutual friction and prolonging the service life of the bushing; and meanwhile, the inwardly-dished bottom surface can easily deform in accordance with the motion process in the use process, so that the bushing has the advantages of more flexible operation and better use effect.
Description
Technical field
The utility model relates to a kind of lining, and particularly heavily card is handled flexible ball joint assembly lining.
Background technique
Heavily the flexible ball joint assembly lining of card manipulation is a kind of important parts that heavily block in the control system, existing heavy card is handled flexible ball joint assembly lining and is comprised lining section and sleeve, be provided with the first inner chamber of opening upwards in the described upper lining section, described sleeve is provided with the second inner chamber that Open Side Down, be provided with dividing plate between described the first inner chamber and the second inner chamber, wherein the bottom surface of sleeve is the plane, in use, lining matches with the metal washer of its underpart, the second inner chamber then is used for holding ball, the bottom surface of sleeve contacts with the metal washer of its below, because the bottom surface that existing heavily card is handled flexible ball joint assembly lining is the plane, so that the area of contact of itself and metal washer is larger, friction mutual in movement process is also larger, thereby affect using effect and the working life of lining, therefore be necessary to improve.
The model utility content
The purpose of this utility model is to provide a kind of heavily card of effectively reducing friction to handle flexible ball joint assembly lining in order to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, the designed a kind of heavy card of the utility model is handled flexible ball joint assembly lining, comprise lining section and sleeve, be provided with the first inner chamber of opening upwards in the described upper lining section, described sleeve is provided with the second inner chamber that Open Side Down, be provided with dividing plate between described the first inner chamber and the second inner chamber, its bottom surface of described sleeve is inner concavity.Because sleeve is inner concavity, thereby lining bottom surface and metal washer area of contact are reduced, thereby effectively reduce mutual friction; In addition, the bottom surface of inner concavity in use is easy to occur the deformation that adapts with movement process, thereby can make the lining running more flexible, also can reduce wear simultaneously.
As preferably, its bottom surface of described sleeve is the arc surfaced of indent.Through test, such scheme using effect is best.
The heavily card that the utility model obtains is handled flexible its beneficial effect of ball joint assembly lining: lining bottom surface and metal washer area of contact reduce, thereby effectively reduce mutual friction, prolong the working life of lining; Simultaneously, the bottom surface of inner concavity in use is easy to occur the deformation that adapts with movement process, thereby can make the lining running more flexible, and using effect is better.
Description of drawings
Fig. 1 is the sectional view that the heavily card of prior art is handled flexible ball joint assembly lining;
Fig. 2 is that embodiment 1 heavily card is handled flexible ball joint assembly lining stereogram;
Fig. 3 is the plan view that embodiment 1 heavily card is handled flexible ball joint assembly lining;
Fig. 4 is the sectional view that embodiment 1 heavily card is handled flexible ball joint assembly lining;
Among the figure: upper lining section 1, sleeve 2 first inner chambers 3, the second inner chamber 4, dividing plate 5, bottom surface 6.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Embodiment 1:
In Fig. 2,3,4, the heavily card that the present embodiment is described is handled flexible ball joint assembly lining, comprise lining section and sleeve, be provided with the first inner chamber of opening upwards in the described upper lining section, described sleeve is provided with the second inner chamber that Open Side Down, be provided with dividing plate between described the first inner chamber and the second inner chamber, its bottom surface of described sleeve is the arc surfaced of indent, because sleeve is inner concavity, thereby lining bottom surface and metal washer area of contact are reduced, thereby effectively reduce mutual friction; In addition, the bottom surface of inner concavity in use is easy to occur the deformation that adapts with movement process, thereby can make the lining running more flexible, also can reduce wear simultaneously, lining bottom surface and metal washer area of contact reduce, thereby effectively reduce mutual friction, prolong the working life of lining; Simultaneously, the bottom surface of inner concavity in use is easy to occur the deformation that adapts with movement process, thereby can make the lining running more flexible, and using effect is better.
Specific embodiment described herein only is to design of the present utility model explanation for example.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Claims (2)
1. one kind is heavily blocked the flexible ball joint assembly lining of manipulation, comprise lining section and sleeve, be provided with the first inner chamber of opening upwards in the described upper lining section, described sleeve is provided with the second inner chamber that Open Side Down, be provided with dividing plate between described the first inner chamber and the second inner chamber, it is characterized in that its bottom surface of described sleeve is inner concavity.
2. heavy card according to claim 1 is handled flexible ball joint assembly lining, it is characterized in that its bottom surface of described sleeve is the arc surfaced of indent.
