Abstract
The utility model discloses a through axle case with an auxiliary lubricating oil hole, which comprises a through axle case with a through hole. The improvement of the through axle case is that the outer surface of the through axle case, close to the position of the through hole, is provided with a first oil hole and a second oil hole, the hole wall of the through hole is provided with a first oil slot and a second oil slot, the first oil hole is communicated with the first oil slot, and the second oil hole is communicated with the second oil slot. The through axle case has the beneficial effect that lubricating oil passes through the first oil hole, the first oil slot, the second oil hole and the second oil slot so as to form a circulation oil path around a bearing, so that a better lubricating effect on the bearing can be realized.
Description
Technical field
The utility model relates to a kind of vehicle drive axle, relates in particular to a kind of perforation axle housing with the lubrication assistant oilhole.
Background technology
Thru shaft between existing perforation axle housing and the main reduction gear is realized lubrication by atomization through the lubricating oil that the gear rotation takes up, and the lubricant effect of this lubricating method is limited, especially to very poor near the lubricant effect of the bearing that connects the axle housing place on the thru shaft.
The utility model content
To the problem in the background technology; The utility model provides a kind of perforation axle housing with the lubrication assistant oilhole, comprise the perforation axle housing that is provided with through hole, its improvement is: connect the position of axle housing outside face near through hole; Be provided with first oilhole and second oilhole; The hole wall of through hole is provided with first oil groove and second oil groove, and first oilhole is communicated with first oil groove, and second oilhole is communicated with second oil groove.
The useful technique effect of the utility model is: lubricating oil forms the circulating oil path around bearing through first oilhole, first oil groove, second oil groove and second oilhole, and bearing is played lubricant effect preferably.
Description of drawings

Fig. 3, through hole position structural profile left-hand view.
The specific embodiment
The structure of the utility model is: comprise the perforation axle housing 1 that is provided with through hole 1-1; Its improvement is: connect the position of axle housing 1 outside face near through hole 1-1; Be provided with the first oilhole 1-2 and the second oilhole 1-3; The hole wall of through hole 1-1 is provided with the first oil groove 1-4 and the second oil groove 1-5, and the first oilhole 1-2 is communicated with the first oil groove 1-4, and the second oilhole 1-3 is communicated with the second oil groove 1-5.
Lubricating oil gets into the first oil groove 1-4 and flows on the bearing from the first oilhole 1-2, and bearing is lubricated, and surplus oil flows in the second oil groove 1-5, flows out through the second oilhole 1-3, forms circulatory lubrication.
