Abstract
The utility model discloses a universal joint which comprises a longitudinal shaft and a transverse shaft perpendicular to each other. The two ends of the longitudinal shaft and the transverse shaft are sleeved with rolling pin bearings, through oil holes are axially formed in the longitudinal shaft and the transverse shaft, and the two oil holes are communicated with each other. A plurality of oil grooves are formed in the end faces of the longitudinal shaft and the transverse shaft, and the oil grooves are communicate with the oil holes. The oil grooves formed in the end faces of the universal joint of the structure are utilized, the end faces can be lubricated, and the oil grooves further can serve as lubricating grease channels between double forks. Lubricating of the end faces is ensured while the lubricating grease channels of the universal joint and the double connection forks are communicated, and maintenance in use is facilitated.
Description
Technical field
The utility model relates to a kind of cross axle, is particularly useful for the cross axle in engineering machinery and vehicle drive unit.
Background technique
More existing engineering machinery and Vehicular turn ransaxle adopt simply connected universal joint as steer-drive conventionally, in the time that transmission angle of yaw is larger, the rotating speed of this drive unit and moment of torsion all can produce larger fluctuation, cause cannot realizing the constant speed transmission between driving shaft and driven shaft in transmission process, and easily cause vibration and damage parts, its noise is also larger, and transmission is steady not, can not meet the stationarity requirement of transmission angle of yaw when larger.Existing solution is generally to have two of employings respectively to have the simply connected universal joint of a junction to be stitched together, as steer-drive.But its form structure is large, axial length is also large, conventionally can not be arranged in the narrow space of steering drive axle joint fork inner chamber, and manufacture cost is higher.
In order to address the above problem, claimant has invented a kind of steer-drive (application number 201020541247.1), and the two ends of the duplex fork of this steer-drive are connected with driving shaft and driven shaft by cross axle respectively; The both ends of the surface of described cross axle are provided with axially stop block.It is not high that this steer-drive has overcome the stationarity that in prior art, simply connected universal joint brings as steer-drive, cannot realize the constant speed transmission between driving shaft and driven shaft and easily cause vibration and a series of defects such as damage parts, also overcome two simply connected universal joints large and problem that cannot install of brought form structure that is stitched together that adopts simultaneously, this steer-drive also can move reposefully in the time of larger transmission angle of yaw, its axial dimension is little, mounting structure compactness, can be arranged on very easily in steering drive axle joint fork inner chamber, simple in structure.
But present cross axle cannot be well lubricated to its axial end, in use, is very easy to because friction damages cross axis faces, and heating is serious, even can cause cross axle fault accident because of heating.After assembling, also cannot inject lubricant grease to cross axle.
Model utility content
For the technical problem of above-mentioned existence, the utility model provides a kind of cross axle, and the oil groove that utilizes its end face to arrange, can lubricate end face, can serve as again the lubricant grease passage between duplex fork.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of cross axle, comprises the orthogonal longitudinal axis and transverse axis; The described longitudinal axis and transverse axis two ends cover have needle bearing; On the longitudinal axis and transverse axis, axially have the oilhole running through, and two oilholes communicate; The described longitudinal axis and transverse axis end face have some oil grooves, and described oil groove communicates with oilhole.
Preferred as one, described oil groove cross section is triangle.Be conducive to lubricant oil circulation.
Improve as one, the described longitudinal axis and transverse axis are eccentric design, be that the axle center of diaxon is not at same plane, can shorten like this axial distance between driving shaft and the universal joint of driven shaft, and solved the little problem in transmission space causing because of after axial distance shortening between driving shaft and the universal joint of driven shaft, and the rotation interference problem of universal joint.Its transmission angle of yaw maximum can reach 60 °.
Preferred as one, the described longitudinal axis and transverse axis intersection are circular arc, and the described longitudinal axis and transverse axis intersection root are conical surface transition or round-corner transition.Utilize level and smooth transition, and without the sudden change of sectional shape, thus the stress that has alleviated cross axle spindle nose root concentrate, improved the intensity of cross axle, reduced the possibility of fatigue fracture.
Usefulness of the present utility model is: have the cross axle of said structure, the oil groove that utilizes its end face to arrange, can lubricate end face, can serve as again the lubricant grease passage between duplex fork.In guaranteeing lubricated end face, by the oil leab UNICOM of cross axle and duplex fork, the maintaining in easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is side-looking structural representation of the present utility model.
Mark in figure: 1 longitudinal axis, 2 transverse axis, 3 needle bearings, 4 oilholes, 5 oil grooves.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1 and Figure 2:
The utility model comprises the orthogonal longitudinal axis 1 and transverse axis 2; The described longitudinal axis 1 and transverse axis 2 two ends covers have needle bearing 3; On the longitudinal axis 1 and transverse axis 2, axially have the oilhole 4 running through, and two oilholes 4 communicate; The described longitudinal axis 1 and transverse axis 2 end faces have some oil grooves 5, and described oil groove 5 communicates with oilhole 4.Oil groove 5 cross sections are preferably triangle.The longitudinal axis 1 and transverse axis 2 are eccentric design, and the axle center of diaxon is not at same plane.The longitudinal axis 1 and transverse axis 2 intersections are circular arc, and intersection root is conical surface transition or round-corner transition.
When use, the longitudinal axis 1 is connected with driving shaft or driven shaft, and transverse axis 2 is connected with duplex fork.Lubricant oil flows into oil groove 5 by duplex fork oil duct, has lubricated the end face of axle.After assembling, not needing dismounting can be directly just directly cross axle injection lubricant grease by the greasing hole on duplex fork.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
