Abstract
The utility model discloses a reinforcement universal-joint fork, which comprises a connecting hub and two fork lugs, wherein the two fork lugs are symmetrically arranged at one end of the connecting hub; two coaxial mounting holes are respectively arranged in the lug parts of the two fork lugs; and a reinforced rib is arranged between root parts of the two fork lugs. Due to the adoption of the technical scheme, the rigidity of a universal joint is increased; in the welding process of the connecting hub and an axial tube, the deformation can be controlled within a tolerance of products of the universal-joint fork; due to analysis by three-dimensional software CAE (Computer Aided Engineering) and comparison of the condition that the universal-joint fork is not heated with the condition that the universal-joint fork is deformed caused by heating, the displacement deformation of the inner sides at the lug parts of the two fork lugs is about 0.1mm and the deformation is remarkably reduced and is consistent with the actually-measured value. The improved universal-joint fork is proper in axial clearance; axial drifting of with large displacement hardly occurs in the high-speed rotating process of the uniform joint; the universal joint cannot be easily failed any longer, so that the difficulty in dynamic balance work procedures is reduced; and in the use process, the designed life of a driving shaft assembly is achieved.
Description
Technical field
The utility model belongs to the automobile production technical field, is specifically related to a kind of reinforcement universal-joint fork that is installed on the miniature driving-shaft assembly.
Background technique
Welding is a kind of manufacturing process of local heating, and welding process and postwelding, component inevitably can produce welding deformation; Welding deformation can influence the performance of weldment under certain condition, and like intensity, rigidity, dimensional accuracy and stability etc., the connection hub of universal-joint fork and central siphon are for being welded to connect in the existing miniature driving-shaft assembly; Weld seam is the ring-type weld seam, and welding manner is CO 2 gas-shielded automatic weldering, in welding process; Because the uneven temperature field that local heating produces and the not high factor of intensity of light-duty universal-joint fork itself make the universal-joint fork amount of deformation very big, make the dimensional accuracy variation of existing universal-joint fork; Strengthen the difficulty of dynamic balancing operation; Had a strong impact on the precision of driving-shaft assembly, along with the increasing gradually of little car transmission shaft demand, welding deformation has restricted the raising of manufacturing efficiency.In addition, by the three-dimensional software cae analysis, contrast before and after the universal-joint fork temperature distortion, about the inboard displacement 0.24mm of the ear of two fork ears, this conforms to actual recording.Because ear's inside dimensions of the fork ear of universal-joint fork becomes big, make universal joint axial clearance become big, the axial float of big displacement appears in universal joint in the high speed rotating process, strengthened the difficulty of dynamic balancing operation; In use, universal joint lost efficacy in advance, had reduced the working life of driving-shaft assembly.
The model utility content
The utility model is in order to solve deficiency of the prior art, provides a kind of and reduces welding deformation, prolonged the driving-shaft assembly reinforcement universal-joint fork in working life.
For solving the problems of the technologies described above; The utility model adopts following technological scheme: a kind of reinforcement universal-joint fork; Comprise connecting hub and being connected symmetrically arranged two the fork ears of hub one end that the ear of two fork ears is respectively equipped with a coaxial mounting hole, is provided with stiffening rib between the root of said two fork ears.
Said stiffening rib, connection hub and two fork ear one forging moldings.
Adopt technique scheme, between the root of two fork ears of universal-joint fork, stiffening rib is set, increased the rigidity of universal-joint fork, in connecting hub and central siphon welding process, amount of deformation is controlled within the product tolerance of universal-joint fork.By the three-dimensional software cae analysis, contrast before and after the universal-joint fork temperature distortion, inboard displacement deformation is that amount of deformation obviously reduces about 0.1mm in the ear of two fork ears, this conforms to actual recording.It is suitable to improve rear universal joint axial clearance, and universal joint is few axial float that big displacement occurs in the high speed rotating process, and universal joint lost efficacy no longer easily, had reduced the degree of difficulty of dynamic balancing operation, and in use, driving-shaft assembly has reached projected life.

Fig. 3 is the plan view of Fig. 1.
Embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3; A kind of reinforcement universal-joint fork of the utility model; Comprise and connect hub 1 and be connected symmetrically arranged fork ear 2 of hub 1 one ends and fork ear 3; Fork ear 2 is respectively equipped with a coaxial mounting hole 4 and mounting hole 5 with the ear of fork ear 3, is provided with stiffening rib 6 between the root of fork ear 2 and fork ear 3.Stiffening rib 6, connection hub 1, fork ear 2 and fork ear 3 one forging moldings.
Between the root of the fork ear 2 of universal-joint fork and fork ear 3, stiffening rib 6 is set, has increased the rigidity of universal-joint fork, in connecting hub and central siphon welding process, amount of deformation is controlled within the product tolerance of universal-joint fork.By the three-dimensional software cae analysis, universal-joint fork is contrast before and after the temperature distortion in welding process, is that amount of deformation obviously reduces about 0.1mm at the inboard displacement deformation of ear of pitching ear 2 and fork ear 3, and this conforms to actual recording.It is suitable to improve rear universal joint axial clearance, and universal joint is few axial float that big displacement occurs in the high speed rotating process, and universal joint lost efficacy no longer easily, had reduced the degree of difficulty of dynamic balancing operation, and in use, driving-shaft assembly has reached projected life.
