HINGE DOOR FOR CAR

The invention relates to the field of automotive industry, in particular to a door hinge, one of the links of which is connected to the body, and the second link to the door.

The prior art design of the hinge door1 for a car (analogue is application DE No. 3401245, class E 05 D 7/00, 5/10, 3/04, publ. 85.07.18; the closest analogue is French application No. 2606822, class. E 05 D 7/10, 5/12, 11/06, 60 J 5/00, publ. 88.05.20. Bull. No. 20). Each of the above structures contains fixed and movable links, the first of which is rigidly attached to the 3rd, and the second to the door. The movable and fixed links are interconnected by an axis of articulation located in two self-lubricating bushings located in the hole of one of the mentioned links of the loop, in particular the stationary one. One of the end parts of each self-lubricating sleeve contains a shoulder made around the entire perimeter of the cylindrical part of the self-lubricating sleeve and placed between the end surfaces of the movable and fixed links, which prevents

friction of the latter among themselves. Each self-lubricating sleeve contains an angular zone, which is the transition zone of the cylindrical part in the shoulder. In the aforementioned closest analogue, the joint axis contains a head inside which there is a cavity for interacting with the screw tool, and a thread is made outside the head for screwing the head into one of the holes of the loop link, said head of the joint axis due to its increased outer diameter also performs the function articulation axis

The described design is easy to use, which avoids the loss of time during installation or dismantling of doors on production lines of the conveyor.

However, when a self-lubricating sleeve is pressed into the hole of one of the loop links, the said angular zone of the self-lubricating sleeve undergoes deformation, i.e. thinning. During the operation of the hinges, this can lead to the detachment of the shoulder from the cylindrical part of the self-lubricating sleeve, which can complicate the operation of the door hinges. This is especially true if the doors have a large mass.

The objective of the invention is aimed at increasing the service life of the door hinges of the vehicle.

To solve this problem, the door hinge for a car contains movable and fixed links interconnected by an axis of articulation located in at least one self-lubricating sleeve located in the hole of one of the links of the loop, and at least one end part of the self-lubricating sleeve is made of a conical shape with the transition of the edge to the shoulder; self-lubricating sleeve placed in the movable link; self-lubricating sleeve placed in a fixed link; each end part of the axis of the joint is made flared;

self-lubricating sleeve contains a cutout made along its axis; the joint axis is located in two self-lubricating bushings, located opposite each other and having a mirror-reflected shape.

The essence of the technical solution is illustrated in the drawings. FIG. 1 - shows a door hinge in which two self-lubricating bushings are used.

Figure 2 - shows a section of a fragment of a door hinge with one self-lubricating sleeve.

FIG. 3 shows a section AA of FIG. 1. FIG. 5 - shows a self-lubricating sleeve with a cutout made

along its axis.

The door hinge 1 for a car contains movable 2 and fixed 3 links connected to each other by an axis of articulation 4 located in at least one self-lubricating sleeve 5 located in one of the mentioned links 2 or 3 (see Figs. 1-3) .

The car door is predominantly mounted on two hinges, namely the lower and upper, so the self-lubricating sleeve 5 can be placed in both the movable and the fixed links, for example, in the upper loop the self-lubricating sleeve 5 is placed in the fixed link, and in the lower loop in the movable link due to the design features of the door hinge.

A further description of the design will be given the fact that two self-lubricating bushings 5 are used, which are located in the fixed link 3 of the loop 1 against each other and have a mirror-like shape, as shown in FIG.

The fixed link 3 of the loop 1 contains a base 6, which is attached to the car body by means of a detachable connection, for example a bolt-nut (not shown in the figures), and a wing 7, on the end part 8 of which a through hole 9 is made, in which the previously mentioned self-lubricating bushings are placed 5.

The output parts 10 of the aforementioned hole 9 of the fixed link 3, into which the self-lubricating bushings 5 are pressed, are made conical in shape, namely, expanding as they approach the end surfaces 11 of the end part 8 (see Fig. 4).

The movable link 2 contains a base 12, with which it is rigidly fixed, for example by welding, to the car door (not shown in the figures), and two tabs 13, between which the end portion 8 of the fixed link 3 is located. Each of the tabs 13 contains a through hole 14 in which is the axis of the joint 4.

The self-lubricating sleeve 5 is made of fluoroplastic and contains an axial hole 15 in which the axis of the joint 4 is located. One 16 of the end parts of the self-lubricating sleeve 5 is made conical with the transition of the edge part to the shoulder 17.

One embodiment of the self-lubricating sleeve 5 is its execution with a cutout 18 (see FIG. 5) made along its axis L, which creates the possibility of additional interference and prevents the rotation of the self-lubricating sleeve 5 in the previously mentioned hole 9.

The movable 2 and the fixed 3 links of the loop 1 are interconnected by the axis of the joint 4 so that the latter is placed in the axial hole 15 of the self-lubricating sleeve 5, pre-pressed in the hole 9 of the fixed link 3, and the holes 14 of the legs 13 of the movable link 2, and the end parts 19

the axis of articulation 4 is filled with flared. The self-lubricating bushings 5 with the outer surfaces of the end parts 16 fit snugly against the output parts 10 of the hole 9, while maintaining a predetermined wall thickness W of the end portion 16. The shoulder 17 of the self-lubricating sleeve 5 is located between the end surfaces 11 and 20 of the end part 8 of the fixed link 3 and the legs 13 of the movable link 2, respectively, with the possibility of contact with them, as shown in figure 3.

The above-described loop design is technologically advanced in manufacturing and assembly and has an increased resource of work.
