Abstract
The utility model relates to a universal joint, in particular to a universal joint crossing shaft with a planar root portion, which mainly resolves technical problems that a conventional crossing shaft universal joint in the prior art is generally made via hot forging, or the universal joint is completed by cold extruding but a gap is preserved between an oil seal and the root portion of the crossing shaft after being used due to the fact that the root portion of the crossing shaft is a conical surface, and the sharp top of the end portion of the crossing shaft scratches a roller pin and the like inside a bearing after the crossing shaft is installed on the bearing. The universal joint crossing shaft with a planar root portion comprises a crossing shaft body (1), installation holes (2) arranged on the crossing shaft body and four shaft bodies (3) connected to the crossing shaft body and is characterized in that the root portion of the crossing shaft body (1) is formed by an arc-shaped surface (4), a planar surface (5) and an inclined surface (6).
Description
Technical field
The utility model relates to a kind of universal joint, and especially relating to a kind of is the isostructural improvement of universal-joint cross trunnion on plane to root.
Background technique
Universal-joint cross trunnion of the prior art is generally all formed by middle axis body and with the arm that middle axis body links into an integrated entity.Chinese patent discloses a kind of high strength Hooke's joint (notice of authorization number: CN 2464984Y), it comprises cross axle and is arranged on the needle roller around the cross axle spindle nose and puts and outer ring that needle roller is outer, the end of outer ring is provided with packing holder, is provided with seal ring skeleton and seal placed on it on described packing holder; And the inboard of described seal is provided with tilting outer lip and inside middle lip and the inner lip of lip successively, and three lips contact with the axle journal of cross axle; Tiltedly be provided with the grinding undercut of annular between internal face and the needle roller end face ring, and the needle roller end face ring with place the cross axle spindle nose end face of needle roller inboard in the same plane, the inboard of needle roller end face ring is provided with the pad chamber, it is built-in with glass nylon Composition spacer, and the exterior edge face of Composition spacer flushes substantially with described needle roller end face ring; The center line of grinding undercut and bottom plane, outer ring are 35 °～55 ° angles, and its degree of depth is 0.25～0.6mm, and the end is the circular arc ring that radius is 0.3～5.0mm.But this Hooke's joint, generally be to make by forge hot, though and the universal joint that has is to be finished by cold hobbing, but its cross axle root is the conical surface, use Rear oil seal and cross axle root can leave a seam, and after cross axle was loaded onto bearing, the spike of cross-member ends can scratch the needle roller of bearing inside.
The model utility content
The utility model technical issues that need to address provide the universal-joint cross trunnion that a kind of root is the plane, it mainly is to solve the existing in prior technology Hooke's joint, generally be to make by forge hot, though and the universal joint that has is to be finished by cold hobbing, but its cross axle root is the conical surface, use Rear oil seal and cross axle root can leave a seam, and after cross axle loads onto bearing, the spike of cross-member ends can scratch the technical problem of the needle roller of bearing inside etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Root of the present utility model is the universal-joint cross trunnion on plane, comprise the cross axle body, have mounting hole on the cross axle body, be connected with four axis bodies on the cross axle body, it is characterized in that the root of described cross axle body is made up of arc surface, plane and inclined-plane.Four axis bodies are arranged in cross, on it bearing can be installed, and are provided with oil sealing between the root of bearing and cross axle body.The utility model is to adopt cold extrusion shapedly, because original cross axle body root is for the ease of the mould withdrawing pattern, thereby is designed to the conical surface.But conical surface meeting and oil sealing produce the slit in actual the use.Two lathe tools are loaded onto by comparatively accurate measuring truck in the plane of cross axle body root, and No. one time clamping is finished.The height dimension of cross axle body is related to the quality of oil sealing sealing effect, and oversize sealing is turned up easily, and too short sealing effect is bad.Root is designed to height dimension and the degree of symmetry that the plane has promptly guaranteed the cross axle body, has also improved manufacturing efficiency.
As preferably, the angle α on described plane and inclined-plane is 5～8 °.
As preferably, the outer end of described axis body is provided with the axle head arc surface, is provided with the axle head inclined-plane between the circumferential surface of axle head arc surface and axis body.Originally the axle head arc surface of the outer end of axis body directly is connected with the circumferential surface of axis body, thereby produces spike, easily needle roller is scratched when the dress bearing.After processing the axle head inclined-plane, spike just unlike so sharp-pointed in the past, can prevent its scratch needle roller.The axle head inclined-plane can directly be gone out by punch press, has improved manufacturing efficiency.
As preferably, the angle β on described axis body circumferential surface and axle head inclined-plane is 18～20 °.Angle β the best can be 18 °.
Therefore, the utlity model has cross axle is made by cold hobbing, its cross axle root is the plane, prevent to leave the slit with Rear oil seal and cross axle root, and establish the axle head inclined-plane in the axis body end, after cross axle is loaded onto bearing, characteristics such as the spike of cross-member ends can not scratch the needle roller of bearing inside, and is simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 4 is B portion structure for amplifying schematic representation of Fig. 3.
Component, position and numbering among the figure: cross axle body 1, mounting hole 2, axis body 3, arc surface 4, plane 5, inclined-plane 6, axle head arc surface 7, axle head inclined-plane 8.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: this routine root is the universal-joint cross trunnion on plane, as Fig. 1, Fig. 3, a cross axle body 1 is arranged, and has mounting hole 2 on the cross axle body, is evenly equipped with four axis bodies 3 on the cross axle body.As Fig. 2, the outer end of axis body 3 is provided with axle head arc surface 7, is provided with axle head inclined-plane 8 between the circumferential surface of axle head arc surface and axis body, and the angle β on its central axis 3 circumferential surfacies and axle head inclined-plane 8 is 18 °.The root of cross axle body 1 is made up of arc surface 4, plane 5 and inclined-plane 6 from the inside to surface successively, and its midplane 5 is 6 ° with the angle α on inclined-plane 6.
During use, between the root of cross axle body and bearing, load onto oil sealing, on four uniform on cross axle body axis bodies 3, load onto bearing again, get final product in the Motor Vehicle of then universal joint assembly that assembles being packed into.
