Abstract
The utility model relates to a torsion transferring device for automobiles, particularly the improvement of structures of universal joints with eccentric type structures, etc. The utility model mainly solves the technical problems that four axle diameter centerlines existing in the prior art are positioned in the same horizontal plane, cross interference is easily generated under some particular cases, or special torsion transferring functions can not be realized, etc. The utility model comprises a cross axle (1), wherein four end parts of the cross axle (1) are provided with bearings (2). The utility model is characterized in that an eccentric distance E exists between an axle line on which two corresponding axle diameters (1-1) of the cross axle (1) are positioned and an axle line on which the other pair of axle diameters (1-2) are positioned.
Description
Technical field
The utility model relates to a kind of automobile with reversing transfer unit, especially relates to a kind of to the isostructural improvement of eccentric structure universal joint.
Background technique
Universal joint generally is made up of cross axle, bearing, lubricating cup etc., forge hot of universal joint shaft bearing outer-ring or cold-extruded or iron sheet are stamped to form, the form of dress fork generally adopts riveted joint, cross axle does not contact with the bearing diapire, by the oil sealing location, the bearing diapire has a platform to convex, and netted pit, cross axle and contact with platform are arranged above the platform.Chinese patent discloses a kind of steering universal joint, and (publication number: CN 2580195Y), it mainly comprises cross axle, bearing and oil sealing, is provided with pad between bearing and cross axle, makes cross axle contact with the bearing diapire by pad.Pad is with wear-resisting and resilient material.But this universal-joint cross trunnion generally all be four diameter of axle centerline on same horizontal plane, the dress fork easily takes place in some cases interfere, perhaps can not realize the special transfer function that reverses.
Summary of the invention
The purpose of this utility model provides a kind of eccentric structure universal joint, it mainly is to solve four diameter of axle centerline of existing in prior technology on same horizontal plane, at some the dress fork easily taking place in particular cases and interfere, perhaps can not realize the special technical problem of reversing transfer function etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Eccentric structure universal joint of the present utility model comprises cross axle, and its four ends are provided with bearing, it is characterized in that two residing shaft axiss of the relative diameter of axle in the described cross axle, with the residing shaft axis of the other a pair of diameter of axle eccentric distance E is arranged.Eccentric distance E decides with concrete different requirement according to the Dimensions of universal joint greater than zero.So in use, be installed on the position of special compactness, can prevent external interference, thereby solve the needs of special machine device transmitting and converting moment of torsion effectively.
As preferably, the oilhole center line of the described diameter of axle and the angled α of shaft axis, 0＜α＜arctgE/L wherein, L is the distance of axial end to the center, and four oilholes communicate, and is convenient to the oil circuit circulation, replenishes the universal joint bearing grease.
As preferably, the oilhole of described relative two diameters of axle is on the same shaft axis, and promptly the oilhole in the middle of the cross axle is a straight hole.Form straight hole, i.e. α=0, this moment, the oilhole of two diameters of axle can communicate, and also can not communicate, and it is relevant with the oilhole diameter, and general non-maintaining can be designed to this kind structure that do not communicate.
As preferably, be provided with axle bowl or dust-proof cover between described cross axle and the bearing, perhaps other dust guard avoids dust to enter universal joint inside, causes wearing and tearing.
As preferably, the central part or the shoulder of described cross axle are provided with lubricating cup.If non-maintaining universal joint can not have lubricating cup.
As preferably, described bearing bottom is provided with lubricating cup.
Therefore, the utlity model has by using the eccentric structure universal-joint cross trunnion, be installed on the special compacted location, can prevent external interference, windup-degree is big, and specialty is practical, transmits and change moment of torsion effectively, characteristics such as rational in infrastructure have solved the needs of specified conditions restriction in automobile or the mechanical transmission.

Accompanying drawing 4 is a kind of generalized sections of embodiment's 2 cross axles.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: the eccentric structure universal joint that this is routine, and as Fig. 1, Fig. 2, it comprises a cross axle 1, its central part is provided with a lubricating cup 4.Four ends of cross axle respectively are provided with a bearing 2, are provided with dust-proof cover 3 between cross axle 1 and the bearing 2.As Fig. 3, two relative residing shaft axiss of diameter of axle 1-1 in the cross axle 1, with the residing shaft axis of the other a pair of diameter of axle 1-2 eccentric distance E is arranged, and the oilhole center line of diameter of axle 1-1 and 1-2 and the angled α of shaft axis, wherein α is arc tgE/L, L is the distance of axial end to the center, and guarantees that four oilholes communicate.
During use, the universal joint automobile of packing into is reversed in the delivery system,, therefore can prevent external interference because two relative residing shaft axiss of diameter of axle 1-1 have eccentric distance with the residing shaft axis of other a pair of diameter of axle 1-2, thus transmitting and converting moment of torsion effectively.
Embodiment 2: as Fig. 4, the oilhole of two relative diameters of axle is on the same shaft axis, and promptly α is 0 degree, and adjacent oilhole can not communicate, and generally is used for non-maintaining product.All the other are with embodiment 1.
Claims (6)
