Universal joint and universal joint are the parts realizing varied angle transmission of power, and for needing the position changing transmission axial direction, it is " joint " parts of the universal driving device of automobile driving system.Universal joint and transmission shaft combine, be called card gear, universal joint comprises universal-joint fork and cross axle, universal-joint fork comprises fork pin, installs neck and mounting head, described fork is worn and is provided with attachment hole, described installation neck and mounting head are coaxially arranged and all in cylindric setting, pin is coupled together by two attachment holes of setting on it and two symmetrical pin of cross axle, and mounting head can be that transmission shaft connects by sheathed axle sleeve.The structure of universal joint and effect are a little as the joint in human limb, and it allows the angle between the part that is connected to change within the specific limits.
In traditional design, joint fork has two kinds of Placements with axle: 1) weld, 2) riveting connects.These two kinds of Placements not only have higher requirement to logistics and technique assembling, are also difficult to because own wt is comparatively large the requirement meeting client's lightweight, low energy consumption; In addition, easily offset and easily wear and tear when transmitting torsion when the mounting head of existing universal coupling fork is connected with transmission shaft by axle sleeve.
Model utility content
It is simple that the purpose of this utility model is to provide a kind of structure, and be less likely to occur skew during connection, sound construction is tight, reduces the integral type joint fork of logistics and technique assembly process, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme:
A kind of integral type joint fork, comprise jaw portion, neck and mounting head are installed, described jaw portion by two symmetrically arranged universal jaws be connected hub portion and form, on two symmetrical universal jaws, concentric is provided with mounting hole respectively, in described mounting hole, wear-resistant sleeve is installed, the bottom of two universal jaws is fixed on and connects in hub portion, connect hub subordinate end and have the rounded bottom being connected with concentric, rounded bottom is installed and is provided with installation neck, neck lower end is installed and is fixedly installed mounting head, described installation neck and mounting head concentric are arranged and all in cylindric, neck external diameter is installed and is greater than mounting head external diameter, mounting head comprises construction section and flat sections, flat sections end face is connected with installation neck end face, described construction section is provided with spline, described construction section outer surface offers the binding groove for being embedded seal ring, the convex annular edge coaxially arranged with construction section is convexly equipped with bottom described binding groove, described convex annular is less than construction section external diameter along external diameter.
Further, construction section is divided into secondary part and live part by described binding groove, and the axial length of described live part is greater than the axial length of secondary part.
Further, described jaw portion, rounded bottom, installation neck and mounting head are formed in one setting.
Further, described wear-resistant sleeve is made up of chromium carbide compounded material.
Compared with prior art, the beneficial effects of the utility model are: adopt joint fork and install the integrated structural design of neck, avoid and weld or riveting Joining Technology between envoy's fork with installation neck, thus decrease logistics and technique assembly process and alleviate own wt; Time construction section and axle sleeve etc. are installed and be connected, live part is as main bearing position, and therefore live part is the main load position of construction section, and its extended length contributes to the torsion transmission strengthening construction section, improves the connection safety reliability of structure; On two symmetrical universal jaws, concentric is provided with mounting hole respectively, and be provided with wear-resistant sleeve in described mounting hole, wear-resistant sleeve is made up of chromium carbide compounded material, greatly strengthen the wear-resisting property of mounting hole, improves the working life of universal coupling fork.To sum up, the utility model structure is simple, is less likely to occur skew during connection, and sound construction is tight, reduces logistics and technique assembly process, and effectively can alleviate own wt.
