Abstract

The utility model discloses a car door hinge device mainly comprises first hinge piece [ 1 ], A second hinge piece [ 2 ], pivot [ 3 ], copper sheathing and copper backing, first hinge piece [ 1 ], A second hinge piece [ 2 ] are articulated through pivot [ 3 ], all imbed the copper sheathing in the shaft hole of first hinge piece [ 1 ], A second hinge piece [ 2 ], copper backing [ 6 ] are overlapped in pivot [ 3 ] and are established between the contact surface of first hinge piece [ 1 ] and A second hinge piece [ 2 ], it has annular oil groove [ 11 ] to open on the copper sheathing inner wall. During the assembly, earlier assemble the hinge, then through the locating hole with door and hinge welding together, later will weld door as an organic whole and hinge mount on the side wall, for adjustment door fit -up gap, division have the slotted hole on the hinge, can remedy the dimensional change who processes the tolerance and bring. The utility model discloses simple structure, processing convenience are used reliably.

Description

A kind of door-hinge device

Technical field

The utility model belongs to the car door field of heavy-duty machinery and armored vehicle, is specifically related to a kind of door-hinge device.

Background technology

The door hinge assy of heavy-duty machinery and armored vehicle by two independently part form, wherein a part is assemblied in car door, and another part is assemblied on gusset.This hinge assembly structure is simple, and according to car door and gusset gap during assembling, weldering two parts are joined at scene; Due to the car door of heavy-duty machinery and armored vehicle and side shell plate material thicker, most employing assembly welding and manual bending moulding process, accessory size tolerance is large, makes to adjust gap round the auto door in assembling very difficult, is difficult to ensure the cooperation requirement between hinge assembly two parts, simultaneously owing to lacking necessary lubrication system, after using a period of time, wear of hinge is serious, can not well rotate, thus cause car door opening and closing forces comparatively large, even cannot open.

Utility model content

The purpose of this utility model is to provide a kind of door-hinge device, can must ensure hinge general assembly precision very well, simultaneously in the use procedure of hinge assembly, wear and tear less, hinge assembly remains good fit dimension, and the phenomenon that car door opening and closing forces are large and cannot open can not occur.

The technical solution of the utility model is: a kind of door-hinge device, is characterized in that: primarily of the first hinge plate 1, second hinge plate 2, rotating shaft 3, copper sheathing and copper backing composition; First hinge plate 1, second hinge plate 2 is hinged by rotating shaft 3; All embed copper sheathing in the axis hole of the first hinge plate 1, second hinge plate 2, copper backing 6 to be enclosed within rotating shaft 3 and to be located between the first hinge plate 1 and the contact surface of the second hinge plate 2; Described copper sheathing inwall has annular oil groove 11.

Beneficial effect: the utility model has the advantage of easy for installation, the installation dimension needed for hinge plate assembly easily ensures; Unique lubrication system, it is little that hinge assembly in use opens and closes power, can not occur to open phenomenon; In addition position limiting structure is simple, reliably spacing.The utility model may be used on the door systems such as heavy engineering machinery and armored vehicle, and the car door installation larger for quality provides a kind of new scheme.

Detailed description of the invention

For making the purpose of this utility model, content and advantage clearly, below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.

Door-hinge device described in the utility model adopts monolithic assembling mode, as shown in Figure 1, forms primarily of the first hinge plate 1, second hinge plate 2, rotating shaft 3, two pieces first copper sheathing 4, second copper sheathing 5, two pieces copper backing 6, nut 7, cottor pin 8; First hinge plate 1, second hinge plate 2 is hinged by rotating shaft 3; All embed copper sheathing in the axis hole of the first hinge plate 1, second hinge plate 2, copper backing 6 to be enclosed within rotating shaft 3 and to be located between the first hinge plate 1 and the contact surface of the second hinge plate 2.

In order to reduce the friction with hardness material between the first hinge plate and the second hinge plate; first copper sheathing 4 adopts interference fit to be assemblied in two axis holes of the first hinge plate 1 respectively; second copper sheathing 5 adopts interference fit in the axis hole of the second hinge plate 2; then with rotating shaft, the first hinge plate 1, second hinge plate 2 is fitted together; matched in clearance is adopted between rotating shaft and each copper sheathing; copper sheathing freely can be rotated in rotating shaft; friction is main between copper sheathing and rotating shaft, protects the axis hole of the first hinge plate 1, second hinge plate 2.Between the first hinge plate 1, second hinge plate 2 contact surface, copper backing is housed, greatly reduce the wearing and tearing between these two parts, be fixed as one by hinge assembly finally by nut screwing clamping, cottor pin is inserted in rotating shaft preformed hole and prevents nut loosening, and hinge general assembly is shown in Fig. 2.In addition the utility model devises unique lubrication system, namely on copper sheathing inwall, has annular oil groove 11, sees Fig. 3, avoid and drive oil groove in rotating shaft and reduce shaft strength.

Of the present utility modelly spacingly to be realized by positive stop lug boss 9 and confined planes 10, as shown in Figure 2.First hinge plate processes positive stop lug boss 9, and along with the rotation of the first hinge plate, positive stop lug boss 9 contacts with the confined planes 10 of the second hinge plate and realizes limit function, as shown in Figure 4.This position limiting structure is simple, easy to process, uses reliable.

During assembling, first that hinge assemblies is good, then by locating hole, car door and hinge are welded together, afterwards the car door be welding as one and hinge are arranged on gusset, in order to adjust car door fit-up gap, hinge having slotted hole, the change in size that machining tolerance brings can be made up.

The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
