Description
Technical field
The utility model relates to body hinge, the door hinge that especially a kind of excavator driver's cabin is used.
Background technology
The door hinge of automobile is the relative position of a kind of definite car door and vehicle body, and can control the device of car door movement locus.Existing excavator driver's cabin side door hinge generally comprises bearing pin, fixed page and active page; Fixed page and excavator cab frame fix, and active page and side door fix, and side door utilizes active page to rotate along bearing pin; Because the oil injecting lubricating of active page and bearing pin is difficulty relatively; Active page can produce the situation of dry friction with bearing pin after using a period of time, can drier and more astringent difficulty during the side door rotation, and be easy to generate abnormal sound.
The utility model content
The technical problem that the utility model will solve provides the door hinge that a kind of excavator driver's cabin is used, and self-lubricating property and rotating property are good, makes excavator driver's cabin side door rotate easily and the difficult abnormal voice that produces.
For achieving the above object; The technical scheme of the utility model is: the door hinge that a kind of excavator driver's cabin is used; Comprise that two ends have the bearing pin of spacing preiection, fixed page, active page; The upper and lower side and the fixed page of bearing pin fix, and the mid portion and the active page of bearing pin are articulated, and are provided with two between active page and bearing pin and the fixed page and have wear-resisting and T type lining self-lubricating property; Between active page and described two linings is interference fits, is matched in clearance between described two linings and bearing pin and the fixed page.
Preferred described lining is processed by the Teflon base material, and is easy to manufacture and cost is lower.
The upper and lower side of preferred described bearing pin and fixed page are to interfix through riveted joint, help enhancing productivity.
Further improve, described active page is provided with a plurality of installing holes, improves assembly performance.
The utility model has wear-resisting and T type lining self-lubricating property owing between active page and bearing pin and fixed page, being provided with two; The greasy property that can keep active page and bearing pin the long period; Improve rotating property, make excavator driver's cabin side door rotate the light and difficult abnormal voice that produces of comparison.
