Abstract

The invention provides a multi-freedom-degree hinge mechanism for an armored vehicle. The multi-freedom-degree hinge mechanism is formed by a hinge I (1), a hinge II (2), a hinge cushion block (3), an adjusting gasket (4), a hinge pin (5), a straight-through type forced filling oil cup, a cap nut, bolts M12, a spring washer and a flat washer part. The hinge I (1), the hinge cushion block (3) and the adjusting gasket (4) are connected to one end of a vehicle body through the bolts. The hinge II (2) is connected to one end of a vehicle door through a bolt. The hinge I (1) and the hinge II (2) are fixedly connected through the hinge pin (5). The hinge pin (5) is locked through the cap nut to be prevented from falling off. The oil cup is installed on the hinge pin (5) to fill lubricating grease. The hinge mechanism achieves the effect of door sealing of the armored vehicle; as the adjusting gasket is arranged additionally, the problem of deformation of the vehicle body and the vehicle door can be solved effectively, and the assembling difficulty is reduced; the defects that more welding work is needed, and assembling errors are large are overcome, and the structural function is achieved easily.

Description

Armored vehicle multiple degrees of freedom linkage

Technical field

The invention belongs to panzer car door technical field, particularly a kind of armored vehicle multiple degrees of freedom hingeMechanism.

Background technology

The design of armored vehicle door sealing is difficult point, and conventional body hinge only rotates one degree of freedom around bearing pin,In the time of fit a door, body hinge installed surface is out of shape and alignment error because car body itself, car door exist,Car door does not often reach seal request after installing, and can not regulate, can only by car body, car door repeatedly school type,The means such as manufacture reach requirement, and production efficiency is low,

Summary of the invention

Object of the present invention is exactly can not fine solution to be out of shape for current armored vehicle body hinge, does not reachThe problem of seal request, proposes a kind of armored vehicle multiple degrees of freedom linkage.

The present invention utilizes simple mechanical movement principle, and the aspect of gaining in strength design, solves armored vehicle car doorThe requirement of the aspects such as the multifreedom motion of linkage is functional, reliability, working strength. Hinge leaf,Bearing pin part material is selected published 40Cr steel, and in addition modifier treatment increases the intensity of parts; HingeCushion block, adjusting pad sheet material are selected published 20 steel.

Armored vehicle involved in the present invention multiple degrees of freedom linkage, by hinge leaf I 1, hinge leafII 2, hinge cushion block 3, adjust pad 4, bearing pin 5, through type forced filling oil cup, acorn nut, M12 bolt,Spring washer, plain washer part form; Hinge leaf I 1, hinge cushion block 3, adjustment pad 4 pass through boltBe connected to car body one end, hinge leaf II 2 is bolted in car door one end, hinge leaf I 1, hingeChain hinge II 2 use bearing pins 5 are connected, and bearing pin 5 use acorn nut lockings, prevent from coming off, finally on bearing pin 5Lubricating cup grease up is installed.

The invention solves armored vehicle door sealing problem; Adjust pad by increase, can effectively make upCar body, car door problem on deformation, reduce assembly difficulty; Solve welding more, the shortcoming that rigging error is large,Body function is easily realized.

Embodiment

The armored vehicle of the present embodiment multiple degrees of freedom linkage, its structure is as shown in Fig. 1 to 7.

The armored vehicle of the present embodiment with multiple degrees of freedom linkage by hinge leaf I 1, hinge leaf II 2,Hinge cushion block 3, adjustment pad 4, bearing pin 5 parts, through type forced filling oil cup, acorn nut, M12Bolt, spring washer, plain washer part form, and whole mechanism adopts the installation that is threaded. Hinge leaf I 1,Hinge cushion block 3, adjustment pad 4 are bolted in car body one end, and hinge leaf II 2 is boltedIn car door one end, hinge leaf I 1, hinge leaf II 2 use bearing pins 5 are connected, bearing pin 5 use acorn nutsLocking, prevents from coming off, and lubricating cup grease up is finally installed on bearing pin 5.

The present invention is mainly used in armored vehicle, heavy vehicle car door is installed, and particularly suitable has special seal requirementArmored vehicle, while being applied on other types armored vehicle, can be according to reference for installation or hermetically-sealed construction notThe people having the same aspiration and interest is integrated page cushion block 3 sizes, adjustment pad 4 quantity and different combinations can meet different automobile typesInstructions for use.

The armored vehicle of the present embodiment multiple degrees of freedom linkage, while usually use, car door opening, closesAll identical with common hinge use, in addition, hinge inside, the inner position-limit mechanism limit of hinge while being opened to 130 °Position locking, door lock locking while closing, in the time having special seal requirement, coordinates secondary lock etc. after closing of the doorAugmentor pulls car door to vertical door-plate direction in car, second free degree works, and car door moves adjustmentDistance 0～3mm, reaches better sealing function.

The armored vehicle of the present embodiment can meet instructions for use completely with multiple degrees of freedom linkage, in knuckle-joint bandLimit function, 130 ° of rotational angles, displacement 0～3mm, adjusts pad according to the not people having the same aspiration and interest of combinationWhole distance is respectively 0.2mm, 0.4mm, 0.5mm, 0.7mm, 0.9mm.
