Description

  The invention relates to an axle gear assembly according to the preamble of claim 1, a method according to claim 10 for attaching an axle gear assembly designed according to claim 1, and a method of attaching an axle gear assembly. With respect to an apparatus according to claim 16 for performing, the method is included within the scope of any one of claims 11-15.

  An axle gear assembly of the kind described at the outset is described in US Pat. No. 6,057,089, in which a crown gear is fastened to a differential housing and meshed with a drive pinion arranged at right angles to the bearing shaft; In one part of the axle housing, on the opposite sides of the rotary shaft of the differential large gear, via two rolling bearings located at approximately equal distance from these differential large gears, the upper part of the bevel gear type And a differential base (differential gear) included therein, and a mounting base for the differential housing is provided, wherein the rotating outer ring of the rolling bearing is connected to the axle housing. Inserted into bearing protrusions aligned with each other and supported on a fixed mounting part, the rotating inner ring of the rolling bearing is seated on the bearing neck of the differential housing, and the differential large It is supported on the collar facing the rotating shaft of the car. Here, the differential housing, the differential unit, the rotating inner ring fitted to the bearing neck, and the cage for guiding the rotating body are It is located in the axle housing part that is deviated from the gear (the direction is different), and the shaft passes in the transverse direction (right angle) with respect to the bearing shaft and passes in the same direction as the shaft of the shaft carrying the drive small gear. It can be inserted into the axle housing as a preinstallable structural unit via the mounting orifice.

  In this type of mounting base, it is considered preferable that the rotating outer ring is directly inserted into the bearing orifice of the bearing protrusion, and in each case, the bearing sleeve provided with the clamping flange is not inserted. Costs can be kept low in terms of structure.

  To further reduce this cost and shorten the length of the structure in the direction of the bearing shaft compared to known mounting bases, it is less difficult to mount a pre-mounted structural unit that also includes a crown gear In this known mounting base, the fixing ring inserted into the groove of the bearing projection serves as the mounting portion, and the pocket-shaped recess is one or both of the bearing projections of the axle housing. When a preinstalled structural unit further including a crown gear is inserted into the bearing protrusion, the axle housing can be elastically expanded in the direction of the bearing shaft.

  In this known mounting base, a pre-installed structural unit including a crown gear must be taken by the structural unit when it is guided through the mounting orifice into an installation position aligned with the bearing shaft. It is tilted from the tilt position. In order to avoid expansion of the axle housing due to the influence of the gear force on the crown gear and to prestress the rolling bearing, the axle housing is subjected to insertion of a pre-installed structural unit containing the crown gear. Due to the spread, prestress is applied in the direction of the bearing shaft.

  In order to apply this pre-stress, in this known mounting base, it is preferable that a spacer (spacer) ring is inserted between the rotating outer ring and its fixed ring in order to correct manufacturing tolerances. It is done. In this known mounting base, the rotating outer ring is inserted into the bearing protrusion at the position where the pre-installed structural unit is installed in order to determine the required thickness dimension of each spacing ring (spacer) ring. It is designed to hit the rotating body. Thereafter, the pre-installed structural unit is adjusted with the rotating outer ring to a position for proper play between the crown gear and the drive small gear. In order to adjust that the distance between the fixing rings, where the axle housing has been unfolded to apply prestress, becomes oversized, the mounting steps described below are provided, and accordingly for proper play The actual distance between the rotating outer ring and the supporting edge of the groove for the associated fixing ring is determined in the stress-free state of the axle housing, so that after the actual distance is determined, the axle The housing can extend in the direction of the bearing axis. In order to adjust for the above-mentioned oversizing, a spacing ring is inserted into the widened axle housing, and the thickness of each spacing ring together with the thickness of the associated fixing ring Designed larger than the actual distance.

  In this known axle gear assembly, mounting the differential gear in the form of a pre-mounted structural unit that is relatively bulky for the crown gear, measuring the actual distance, and expanding the axle housing. This is not always easy when the pre-installed structural unit is in the installation position and the space conditions are limited.

This advantage also applies to the spacing (spacer) disc 33 which adjusts the design position of the drive pinion 27 in the direction of the bearing shaft 32-32 of the input shaft 10 in the installed state. This is because the spacing (spacer) disc 33 is also inserted between the corresponding support surfaces 43 and 58 of these housing parts before the housing insertion part 23 is movably adjusted and connected to the housing bottom 22. Because it can be done.

Spacer) achieved by measuring instructions for pre-installable “differential gear” and “housing insert” structural units to determine the required thickness dimension of the disc.

Accordingly, the design of this spacing (spacer) disc 30 before inserting each spacing disc (spacer) disc 30 into the bearing projection 15 of the housing bottom 22 for mounting the axle gear assembly according to the present invention. A dimension S2 that defines the position is determined using the differential distance calculated on the basis of the comparative measurement S2 = D2 + MWT-C2. Here, the expression D2 is the bearing shaft of the differential gear 9 of the mounting surface 35 of the bearing projection 15 for the bearing contact portion of the corresponding spacing (spacer) disc 30 from the reference point P14 in the installed state. in that direction of the housing axis ₁₄ 22 _{-14 22} intersecting with 14-14 represents a distance 34 which is adjusted on the housing bottom 22, wherein MWT is equal to the set desired value of the reference plane 53, wherein C2 is It is equal to the actual value of the distance 62 from the bearing surface 63 to the reference surface 53 at the end on the rotating outer ring 28 for the bearing contact portion of the spacing disk 30.

The center axis intersects with the bearing axis 14-14 of the differential gear 9 in the installed state. Formula A2 is equal to the actual value of the distance 64 from the dividing surface 37 of the housing bottom 22 to the mounting surface 35 of the bearing projection 15 of the housing bottom 22. Equation B3 represents the actual value of the mutual distance 65 between the bearing surfaces 63 and 66 at both ends of the rotating outer rings 28 and 29 for the bearing contact portion of each spacing disc 30 or 31. Formula S2 is equal to the dimension which determines the design position of the other spacing disc 30 assigned to the bearing projection 15 of the housing bottom 22.

  For the described “pre-insertion”, at least one spacing disc during mounting of the axle gear insert according to the invention and between the corresponding support surfaces 43 and 58 of the housing bottom 22 and of the housing insert 23 Before each insertion 33, the dimension S1 defining the design position of this spacing disc 33 is calculated using the differential distance based on the comparative measurement S1 = A1 + MWA−B1. Here, A1 indicates the actual value of the distance 61 from the support surface 58 of the housing insertion part 23 for the bearing contact portion of the spacing disc 33 to the reference surface 59, and MWA is set for the reference surface 59. B1 represents the actual value of the distance 42 from the reference point P32 to the support surface 43 of the housing bottom 22 for the bearing contact portion of the spacing disc 33.
