FIG. 1 is an exploded perspective view of an axle housing assembly for a work machine according to an embodiment of the present disclosure;
FIG. 2 is a side elevational view of the drive axle housing in the axle housing assembly shown in FIG. 1.
Detailed Description
Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings. The described embodiments are not intended to limit the present invention, but are merely exemplary, and not all the features or combinations thereof described in the embodiments are essential to the present invention.
Fig. 1 shows a three-dimensional structure of an axle housing assembly of a working machine according to an embodiment of the present invention. FIG. 2 shows a side view of the transaxle case in the axle case assembly.
As shown in FIG. 1, the axle housing assembly in this embodiment includes a transaxle housing 10 and a final drive assembly 20. The final drive assembly 20 includes a final drive and a differential housed in a final drive case, and is assembled to the transaxle case 10 by a plurality of mounting bolts 30. The final drive assembly 20 is positioned relative to the transaxle case 10 using a locating pin before the final drive assembly 20 is assembled to the transaxle case 10 by the mounting bolts 30.
As shown in fig. 1, three dowel pins 11, 12, 13 are provided on the transaxle case 10, and the three dowel pins 11, 12, 13 can be inserted into three corresponding pin holes 21, 22, 23 formed in the final drive case. In the present embodiment, the three positioning pins 11, 12, 13 are preassembled into corresponding recesses on the transaxle case 10. In another embodiment, the three dowel pins 11, 12, 13 may also be constituted by cylindrical bosses integrally formed on the transaxle case 10. In further embodiments, three locating pins 11, 12, 13 may be provided on the final drive housing and may be inserted into corresponding pin holes formed in the transaxle case 10.
The transaxle case 10 in the present embodiment is a monoblock type axle case. As shown in fig. 1, a mounting hole 14 for mounting a final drive assembly 20 is provided in a central portion of the transaxle case 10. The open end face of the mounting hole 14 forms a positioning plane 15. Three positioning pins 11, 12, 13 are arranged on the positioning plane 15. The final drive housing of the final drive assembly 20 has a mounting plane or flange corresponding to the locating plane 14 of the transaxle case 10.
In the present embodiment, the three positioning pins 11, 12, 13 are different in height. Specifically, the height of the positioning pin 11 is greater than the height of the positioning pin 12, and the height of the positioning pin 12 is greater than the height of the positioning pin 13. To assemble the final drive assembly 20 to the transaxle case 10, the uppermost locating pin 11 is first inserted into a corresponding pin hole 21 in the final drive housing, and the locating pin 11 can serve as a guide during subsequent assembly. Then, the positioning pins 12 and 13, which are shortened in height, are inserted into their corresponding pin holes 22 and 23 in turn. Compared with the prior art that the heights of the three positioning pins are the same, the connecting structure of the drive axle housing and the main reducer assembly in the embodiment adopts the positioning pins with different heights, so that the main reducer housing is easily assembled with the drive axle housing.
Although the heights of the three positioning pins 11, 12, 13 are different in the present embodiment, this is not essential to the invention. For example, the positioning pins 12 and 13 may have substantially the same height, and as long as the height of the positioning pin 11 is greater than the heights of the positioning pins 12 and 13, a guiding function can be performed to simplify the assembly process.
In addition, in the coupling structure according to the present invention, the number of the positioning pins is not limited to three. For example, two positioning pins may be provided only on the transaxle case or the reduction gear case, and the height of one positioning pin may be larger than that of the other positioning pin.
