Abstract
The utility model provides a tractor driver's cabin door hinge structure, includes: round pin axle, plastics axle sleeve, hinge fixed portion, split damping ring, hinge movable part. With two plastics axle sleeves correspond from top to bottom install hinge fixed portion's round pin shaft hole in, should wear hole on the hinge movable part and the pore pair on the fixed portion together through the round pin axle, and fix the screw tip at the round pin axle with split damping ring, through the assembly of hinge movable part and door glass, pass through the door on hinge fixed portion assembles tractor driver's cabin skeleton. The utility model discloses the simple compactness of whole hinge structure is rotated in a flexible way, has high wearing feature and good damping effect, and guarantees easily that the hinge is coaxial, the round pin axle is fixed through split damping ring, and the round pin axle is difficult for droing.
Description
Technical field
The utility model belongs to tractor field, relates to a kind of structure of tractor cab body hinge.
Background technology
At present, more domestic big-power tractor cab vehicle door hinges are mostly adopted and standing part and movable part are assembled together by bearing pin, by the structure that cottor pin is fixing.Body hinge is foundry goods, and articulate part is by parcel rubber.Owing to manufacturing and the restriction of assembly technology, and hinge is rotational motion pair, and hinge axiality not easily ensures; In addition tractor operating mode is severe, easily admix dust in hinge opening and closing process, bearing pin and hinge frictional resistance are increased, weares and teares and accelerate, in Long-Time Service process, car door assembly can be caused to rock in hinge connection, produce the phenomenon such as noise, automobile door glass explosion.For solving existing body hinge Problems existing, improve presentation quality, strengthen abrasion resistance and dust fastness, it is necessary for therefore, developing a kind of compact conformation, having the tractor cab car door hinge structure of high-wearing feature and good damping result.
Utility model content
The purpose of this utility model is to provide a kind of compact conformation, has the tractor cab car door hinge structure of high-wearing feature and good damping result.
The technical solution of the utility model is: a kind of tractor cab car door hinge structure, comprising: bearing pin, plastic sleeve, hinge fixing part, split washer, articulate part.Two upper and lower correspondences of plastic sleeve are installed in the pin shaft hole of hinge fixing part; Be worn together corresponding with the hole on standing part for the hole in articulate part by bearing pin; And split washer is fixed on the thread head of bearing pin; Assembled by articulate part and automobile door glass, car door is assembled on tractor cab skeleton by hinge fixing part.
The utility model can reach following beneficial effect after adopting technique scheme: whole hinge arrangement is simply compact, rotates flexibly, has high-wearing feature and good effectiveness in vibration suppression, and is easy to ensure that hinge is coaxial; Bearing pin is fixed by split washer, bearing pin difficult drop-off.
Accompanying drawing explanation
Fig. 1 is the decomposing schematic representation of a kind of tractor cab car door hinge structure of the utility model;
Fig. 2 is the assembling schematic diagram of a kind of tractor cab car door hinge structure of the utility model.
Detailed description of the invention
Below by Fig. 1, Fig. 2, the utility model is described in further detail.A kind of tractor car door hinge structure, mainly comprises: bearing pin 1, plastic sleeve 2, hinge fixing part 3, split washer 4, articulate part 5, forms hinge assembly by assembling.First two plastic sleeve about 2 correspondences are installed in the pin shaft hole of hinge fixing part 3; Secondly be worn together corresponding with the hole on standing part 3 for the hole in articulate part 5 by bearing pin 1; Then split washer 4 is fixed on the thread head of bearing pin 1; Assemble finally by articulate part 5 and automobile door glass, car door is assembled on tractor cab skeleton by hinge fixing part 3.
Assemble the flange arrangement plastic sleeve 2 of high abrasion and self-lubricating between articulate part 5 and standing part 3, in rotation process, frictional resistance is little, rotates flexibly, has high-wearing feature and good effectiveness in vibration suppression; Bearing pin 1 root is designed to straight knurling structure, and assembling rear pin shaft 1 is integrated with articulate part 5 one-tenth, and ensure that in rotation process, bearing pin 1 and plastic sleeve 2 relatively rotate, hinge abrasion resistance is high, and is easy to ensure that hinge is coaxial; Bearing pin 1 is fixed by split washer 4, prevents bearing pin 1 from coming off.
The utility model tractor car door hinge structure is lightweight, and rotate flexibly, noise is low, and abrasion resistance is high, has the feature such as self-lubricating and good airproof performance.
