Abstract
The utility model relates to a universal connection joint body structure which comprises two universal joint bodies which are respectively connected with a half shaft in a hinged mode. Two ends of each universal joint body are respectively provided with two X-shaped structures which are perpendicular to each other, each of the X-shaped structure is provided with a perforative through hole which is used to hinge adjacent parts, the two universal joint bodies are respectively connected with a middle shaft which is arranged between the two universal joint bodies in a hinged mode through a pin shaft, and the middle shaft is provided with pin shaft penetrating holes which are used to hinge the two universal joint bodies. Only two layers of structures are arranged on each hinged portion of the universal joint bodies: the half shaft and a universal joint. Under the condition that needle bushes of the same specification and the same tactical diameter of the half shaft needle bushes are used, the universal connection joint body structure has a minimum radial size and is beneficial to meeting the operating requirement of a compact accommodation space.
Description
Technical field
The utility model relates to a kind of universal connection joint body structure.
Background technique
The universal joint of the cross axle structure that adopts usually has single cross axle universal joint and double universal joint pin cardan joint, and the single cross axle universal joint adopts common fork configuration, here no longer narration.
Double universal joint pin cardan joint is divided into fork configuration and fist structure according to the semiaxis structure, and conventional fork configuration is also no longer narration here.Common fist structure has an axle to be installed in the semiaxis fist hole, and outside socket is again advanced in the hole of a direction of connecting body (directions X), and connecting body respectively stretches out a minor axis at another direction (Y direction) two ends, is inserted in the hole of a connecting ring again.Like this, in the diametric(al) structure that just haves three layers: semiaxis, connecting body, connecting ring, under the identical situation of the needle bush that adopts same size and semiaxis needle bush swing diameter, the radial dimension of whole universal joint is bigger, needs bigger holding space.
Summary of the invention
The purpose of the utility model is to provide a kind of universal connection joint body structure, and this universal connection joint body all has only double-layer structure in each articulated position: semiaxis and cardon link; Realized under the situation of needle bush that adopts same size and identical semiaxis needle bush swing diameter, having minimum radial dimension, helped to satisfy the usage requirement of compact holding space.
The technological scheme of the utility model is: a kind of universal connection joint body structure; Comprise two hinged with semiaxis respectively cardon link bodies; The two end part of said cardon link body are provided with orthogonal two fork configurations respectively; Said fork configuration be provided be used for the adjacent zeros parts hinged run through through hole; Said two cardon link bodies are hinged through bearing pin and the jack shaft that is arranged between the two cardon link bodies respectively, and said jack shaft is provided with and is used for the bearing pin perforation hinged with two cardon link bodies.
In a preferred embodiment, the two end part of said bearing pin through needle roller and needle bush with run through through hole and cooperate.
In a preferred embodiment, said needle bush is realized axially locating through being arranged on the axle that runs through in the through hole with check ring.
The advantage of the utility model is: through improving; The axial dimension that radially reaches of having realized whole universal connection joint body structure reaches minimum (employing needle bush structure; Under identical corner and moment of torsion transmission situation), help to satisfy the usage requirement of compact holding space.All part shape rules, simple in structure, to be convenient to make, materials consumption is less, thereby can practice thrift manufacture cost greatly, has favorable social and economic benefits.Under the comprehensive containing spatial condition of minimum, this universal connection joint body structure has maximum moment of torsion bearing capacity, is particularly suitable for vehicle, the use of engineering machinery steering drive axle jackshaft, also is suitable for other mechanical corresponding uses.

Embodiment
For letting the above-mentioned feature and advantage of the utility model can be more obviously understandable, hereinafter is special lifts embodiment, and conjunction with figs., elaborates as follows.
With reference to figure 1 ~ 4; The universal connection joint body structure of the utility model; Comprise respectively the two cardon link bodies 2 hinged with semiaxis 1, as can be seen from the figure this cardon link body 2 is a sleeve, and the two end part of said cardon link body 2 are provided with orthogonal two fork configurations 3 respectively; This fork configuration 3 is for being arranged on the lip part on the sleeve ends; Said fork configuration 3 be provided be used for the adjacent zeros parts hinged run through through hole 4, said two cardon link bodies 2 are hinged through bearing pin 5 and the jack shaft 6 that is arranged between the two cardon link bodies 2 respectively, said jack shaft 6 is provided with and is used for the bearing pins perforation 10 hinged with two cardon link bodies 2.
In a preferred embodiment, the two end part of said bearing pin 5 through needle roller 7 and needle bush 8 with run through through hole 4 and cooperate.
In a preferred embodiment, said needle bush 8 is realized axially locating through being arranged on the axle that runs through in the through hole 4 with check ring 9.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
Claims (3)
