を少なくすることが出来る。(Industrial Application Field) The present invention relates to an axle drive device in which a differential gear is fitted. (Prior art) Conventionally, this type of axle drive device is equipped with a differential device in which the tooth surface of the ring gear faces in the opposite direction to the differential case, and the opening into which the differential device is installed is oriented in the longitudinal direction. In the axle housing, which has a substantially straight tube shape and holds a pair of bearings that support the differential gear on its inner surface, the direction in which the differential gear is installed is lower than the bevel pinion gear insertion hole formed in the body of the axle housing. It is known that the axle housing wall on the rear side is recessed inward to form a differential gear positioning step that regulates the position of the bearing on the rear side in the installation direction when the differential gear is assembled. (For example, Tokuraisho 62-2
(See Publication No. 3820). (Problem to be Solved by the Invention) In the conventional axle drive device, when the differential gear is assembled, the end face of the bearing on the back side in the assembly direction is brought into contact with the positioning step of the differential gear via a shim. The ring gear is positioned in contact with the bevel pinion gear, and the engagement between the ring gear and the bevel pinion gear is adjusted.However, since a differential device and a pair of bearings are interposed between the shim and the ring gear, shim adjustment is not easy, and the axle The problem was that the distance from the open end of the housing to the shim was long, resulting in poor workability. The present invention has been made in view of the above-mentioned problems of the conventional technology, and its purpose is to facilitate the assembly of differential gears, bearings, etc. to the axle housing, and also to facilitate assembly of the differential gear, bearings, etc. It is an object of the present invention to provide an axle drive device that improves the meshing precision with a bevel pinion gear and has less uneven contact of the gear in the driving state and less uneven wear of the gear. (Means for Solving the Problems) In order to solve the above problems, the present invention forms a stepped portion on the inner wall of the axle housing for positioning a bearing that supports the differential device on the opposite side of the ring gear. Preferably, the outer diameter of the bearing supporting the differential on the side opposite to the ring gear is smaller than the outer diameter of the bearing supporting the differential on the ring gear side. Further, it is preferable to provide a clearance between the end face of the bearing supporting the differential on the opposite side of the ring gear and the differential case surface so that the differential case can slide in the left-right direction. (Operation) The bearing that supports the differential on the opposite side of the ring gear is inserted and positioned until it abuts against the step. Then, the tip of the differential case is easily inserted into the inner diameter of the bearing, shim adjustment is performed by the clearance between the end face of the bearing and the surface of the differential case, the ring gear is positioned at a predetermined position, and a predetermined mesh is established between the ring gear and the bevel pinion gear. Works to make adjustments. (Example) Examples of the present invention will be described below based on the accompanying drawings. Fig. 1 is an overall side view of a tractor equipped with the axle drive device of the present invention, Fig. 2 is a rear view with the axle drive device attached to the right front wheel, and Fig. 3 is an enlarged cross-sectional view of the main parts. be. As shown in FIG. 1, the tractor 1 has a pair of left and right steered driven front wheels 2.2 and non-steered driven rear wheels 3.3.
The rotational output of the transmission 4 is transmitted via the input shaft 5 to a ring gear 8 which is fitted integrally with the differential device 7 in the axle housing 6 shown in FIG. It is transmitted by meshing, and furthermore, the differential gear 7, the interlock @ 10, the vertical shaft 11, the axle 1
2 to the front wheels 2.2. The axle housing 6 is formed into an integral straight tube shape by casting, and a differential device 7 and a ring gear 8 are connected from one open end 13.
A bearing 14 that is fitted together and supports the differential gear 7
A positioning convex portion 15 is formed on the inner wall, and the bearing 14
A shim 16 is provided between the convex portion 15 and the convex portion 15. Furthermore, a stepped portion 19 is formed on the inner wall for positioning a bearing 18 that is inserted from the other open end 17 of the axle housing 6 and supports the differential device 7 on the opposite side of the ring gear 8. Further, as shown in FIG. 3, the outer diameter of the bearing 18 fitted on the back side of the open end 13 into which the differential gear 7 is inserted is made smaller than the outer diameter of the bearing 14 fitted on the front side. A clearance 21 is formed between the end surface of the bearing 18 and the surface of the differential case 20 so that the differential case 20 can slide in the left-right direction. Further, the inner wall surface of the axle housing 6 is formed in a tapered shape so that the inner diameter of the open end 13 of the axle housing 6 into which the differential device 7 is inserted is the largest, and the inner diameter of the axle housing 6 decreases as it goes deeper from the open end 13. ing. The operation of the axle drive device configured as described above will be explained below. First, the bearing 18 is fitted from the open end 17 of the axle housing 6 until it comes into contact with the stepped portion 19, and then the bearing 18 is locked with the circlip 22. Next, after fitting and inserting the bearing 14 and ring gear 8 into one end of the differential device 7, they are locked with the circlip 23 and assembled, and then inserted from the open end 13 of the axle housing 6, and the other end of the differential device 7 is assembled. The end is fitted into the bearing 18, and further fitted until the end surface of the bearing 14 comes into contact with the protrusion 15 via the shim 16. Here, the shim 16 is easily adjusted by the clearance 21, and the ring gear 8 is positioned at a predetermined position.
The meshing adjustment is made between the ring gear 8 and the bevel pinion gear. Note that the vehicle body rolling bin 26 is inserted into the through hole formed in the bracket 24 integrated with the axle housing 6 and the through hole formed in the bracket 25.25 on the vehicle body side, so that the axle housing 6 can swing freely with the vehicle body. Since they are connected, even if the left and right front wheels 22 move up and down, the rolling bins 26 absorb the rolling and do not twist the vehicle body. (Effects of the Invention) As explained above, according to the present invention, the bearing supporting the differential device on the opposite side to the ring gear is inserted and positioned from the open end opposite to the insertion open end of the differential device. Since the stepped portion is formed on the inner wall of the axle housing, assembly work efficiency is improved. Further, since the outer diameter of the bearing supporting the differential device on the side opposite to the ring gear is made smaller than the outer diameter of the bearing supporting the differential device on the ring gear side, assembly becomes easier. Furthermore, by providing a clearance between the end face of the bearing and the differential case face, it is easier to adjust the shims for adjusting the meshing between the ring gear and the bevel pinion gear, which reduces uneven contact of the gear during driving, and also reduces the unevenness of the gear. It is possible to reduce the decrease.
