Abstract
An adjusting nut assembly for an automobile drive axle differential is arranged on the outer side of a bearing which supports a differential shell body. An inner ring of the bearing is sleeved on a column-shaped differential outer shell (6) in an inlaid mode. Threads are adopted to adjust an adjusting nut. The end face of the inner side of the nut is contacted with the end face of the bearing. A groove (5) used for mounting and placing a locking-stopping mechanism is arranged on the end face of the outer side of the nut. The adjusting nut assembly for the automobile drive axle differential is characterized by further comprising an oil gathering cover (2). One end of an adjusting nut (1) is in press fitting with the oil gathering cover (2), and a cavity is arranged at the bottom of the oil gathering cover (2) and one end of the adjusting nut (1). The cavity is a temporary oil gathering cavity (3). The oil gathering cover (2) is provided with an opening and is communicated with the differential outer shell (6). A plurality of oil inlets (4) are arranged on an end portion where the adjusting nut (1) is contacted with the bearing. Lubricating oil enters into the temporary oil gathering cavity (3) through the oil inlets (4) and then enters into the differential from the temporary oil gathering cavity (3), and therefore interior parts of wheel gears, spacers and the like of the differential can be lubricated well, and a lubrication condition of the differential is improved.

The technical solution of the utility model is achieved in that a kind of automobile drive bridge speed differientiator adjusting nut assembly, be arranged in the outside of the bearing that supports differential casing, bearing inner ring is nested on the differential mechanism shell 6 of cylindricality, adjusting nut adopts threaded adjustment, the nut inner side end contacts with bearing face, nut outside end face is provided with groove 5 and is used for laying lockable mechanism, adjusting nut assembly described in the utility model also comprises oil pooling hood 2, adjusting nut 1 one ends and oil pooling hood 2 press-fits and oil pooling hood (2) bottom has a cavity with adjusting nut one end, this cavity is interim collection chamber (3), oil pooling hood (2) is provided with opening and communicates with the differential mechanism shell, lubricant oil in the oil pooling hood 2 can be entered in the differential mechanism shell, and the end that adjusting nut 1 contacts with bearing is provided with several filler openings 4.
The adjusting nut assembly provides an interim collection chamber 3 for differential mechanism is lubricated, lubricant oil enters interim collection chamber 3 by filler opening 4, enter differential mechanism from interim collection chamber 3 again, the inner bodies such as gear, pad of differential mechanism are well lubricated, prolong the differential mechanism operating life.
Foregoing a kind of automobile drive bridge speed differientiator adjusting nut assembly, its oil pooling hood 2 is a convex cover body, formed by the protruding cylindricality cover body that connects with it on base and the base, aforementioned adjusting nut 1 one ends are adjusting nut inner side surface one ends, and the internal diameter of oil pooling hood 2 protruding cylindricality cover bodies is greater than the internal diameter of adjusting nut.
Adjusting nut assembly after the improvement, its collection chamber 3 is non-totally enclosed type, because the internal diameter of oil pooling hood 2 protruding cylindricality cover bodies is greater than the internal diameter of adjusting nut, so that interim collection chamber 3 internal adjustment nuts one end is higher than oil pooling hood 2 one ends, after lubricant oil enters interim collection chamber 3 by filler opening 4, can not flow out from adjusting nut is open, and only can be along the cylindricality cover body inflow differential mechanism of oil pooling hood 2 projections, the inner bodies such as gear, pad of differential mechanism are well lubricated.
