Abstract
The utility model discloses a differential cross shaft, personally experience sth. Part of the body and be four planetary gear axles that the cross was arranged on the centre links the body including middle hookup, four planetary gear axles were personally experienced sth. Part of the body to whole cold forging spare with middle the hookup, and the inlet port that links the one side of personally experiencing sth. Part of the body in the middle of the center of planetary gear axle is equipped with the through -hole and locates communicates with each other its characterized in that: the outer face of cylinder of planetary gear axle is equipped with the annular shallow slot that many axials were laid, and many annular shallow slots stagger on the circumferencial direction each other, and the circumference angle of every annular shallow slot is not more than 120 degrees, packs the metal powder sintered body in the annular shallow slot, the outer face of cylinder of planetary gear axle still is equipped with many axial shallow slots, and annular shallow slot is connected to the one end of axial shallow slot, and the terminal surface of planetary gear axle is connected to the other end, and the terminal surface of planetary gear axle is equipped with the terminal surface straight flute, and the terminal surface straight flute is with the central through hole and axial shallow slot intercommunication of planetary gear axle. The utility model discloses the greasy property can be improved greatly, the axle journal wearing and tearing are reduced.
Description
Technical field
This utility model relates to the parts of a kind of automobile differential, is specifically related to a kind of differential spider.
Background technology
Automobile differential is the main part of automobile drive axle, and when automobile turning, the radius of turn of two wheels is different, need a wheel turn hurry up one a little slower, two-wheeled different rotating speeds to be realized, it is necessary to realize by differential mechanism, differential mechanism has a cross axle, equipped with four planetary gears.Differential spider fault main cause is the abrasion of trunnion journal (i.e. planet gear shaft), abrasion be because lubrication not ideal enough caused by, abrasion due to planetary gear axle, make trunnion journal and bearing clearance excessive, the cross axle generation that is in operation is rocked, make center transmission shaft line deviate its rotation centerline, make power transmission shaft produce to flutter phenomenon and in running power transmission shaft send the phenomenon of abnormal voice.
Summary of the invention
In view of currently known technology Problems existing, the purpose of this utility model is intended to provide a kind of and improves greasy property, reduces the differential spider of journal wear.
This utility model has adopted the following technical scheme that:
Differential spider, including middle connected body and four planetary gear axles arranging in cross on middle connected body, article four, planetary gear axle is integral cold forging part with middle connected body, the center of planetary gear axle is provided with through hole and communicates with the fuel feed hole being located at middle connected body side, it is characterized in that: the external cylindrical surface of planetary gear axle is provided with the annular shallow slot of a plurality of axial laying, a plurality of annular shallow slot staggers in a circumferential direction mutually, the circumferential angle of every annular shallow slot is not more than 120 degree, filler metal sintered powder in annular shallow slot.
The external cylindrical surface of planetary gear axle is additionally provided with a plurality of axial shallow slot, one end of axial shallow slot connects annular shallow slot, the other end connects the end face of planetary gear axle, and the end face of planetary gear axle is provided with end face straight trough, and the central through hole of planetary gear axle is connected by end face straight trough with axial shallow slot.
After adopting technique scheme, first, the external cylindrical surface of planetary gear axle is provided with annular shallow slot, filler metal sintered powder in annular shallow slot, so under the premise of external cylindrical surface intensity not affecting planetary gear axle, utilize the porous of sinter from metal powder, so as to soaking by lubricating oil, and then raising greasy property, reduce journal wear；It addition, sinter from metal powder directly can be carried out fuel feeding by fuel feed hole by axial shallow slot, end face straight trough, planetary gear axle central through hole, improve for oil-proofness, and then ensure trunnion journal lubrication, improve greasy property, reduce journal wear.
Accompanying drawing explanation
This utility model has drawings described below:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
nullAs shown in the figure，Differential spider of the present utility model，Including middle connected body 1 and four planetary gear axles 2 arranging in cross on middle connected body 1，Article four, planetary gear axle 2 is integral cold forging part with middle connected body 1，The center of planetary gear axle 2 is provided with through hole and communicates with the fuel feed hole 8 being located at middle connected body 1 side，The external cylindrical surface of every planetary gear axle 2 is provided with the annular shallow slot 4 of four axial layings，Article four, annular shallow slot 4 staggers in a circumferential direction mutually，The circumferential angle of every annular shallow slot 4 is not more than 120 degree，Filler metal sintered powder 3 in annular shallow slot 4，The external cylindrical surface of every planetary gear axle 2 is additionally provided with four axial shallow slots 5，Every corresponding annular shallow slot 4 of axial shallow slot 5，One end of axial shallow slot 5 connects annular shallow slot 4，The other end connects the end face 7 of planetary gear axle，The end face 7 of planetary gear axle is provided with end face straight trough 6，The central through hole of planetary gear axle 2 is connected by end face straight trough 6 with axial shallow slot 5.
