ブレーキ装置の組立作業を行うことが可能になる。When the shaft-side friction plates are externally fitted to the boss member in a state where they are not detached, the plurality of shaft-side friction plates and the case-side friction plates arranged between them are, in other words, almost all of the friction plates. The boss member can be pre-assembled. Therefore, when assembling the side brake, a. The pre-assembled boss member is mounted in the differential case in advance, and then the remaining one case-side friction plate is set. b. One case-side friction plate is set in the differential case, and the boss member that has been preliminarily assembled is mounted in the differential case. That is, it is only necessary to perform any of the assembling work. In either case, the number of man-hours required for assembling is increased, but most of the steps can be performed without space restrictions such as setting to the boss member. This makes it easier and faster to perform the assembly work of the side brake device.

い込み変形のおそれがより少なくなる。In addition, in the conventional means in which the shaft-side friction plate is mounted on the differential shaft by fitting in a square cross section, there is a possibility that the shaft-side friction plate and the differential shaft are liable to bite and deform due to a large load torque. However, in the case of the present invention in which the boss member is interposed, the risk of the biting deformation is further reduced by increasing the radius of the fitting portion.

る。In addition, the differential case is divided into two parts in the axial direction, and the case-side friction plate is directly fitted on the inner peripheral surface of one of the cases, and the case-side friction plate is axially attached to the differential case. Since it is fitted in a slidable state and in a state of transmitting torque, that is, the case side friction plate is fitted in the above state by directly using the case itself, so that the case side No special member for fitting the friction plate is required.

うになった。Therefore, according to the present invention, the assembling operation can be simplified and speeded up without any problem in the function of the device by a relatively simple modification in which the boss member is detachably interposed. By using the differential case itself as a part of the brake device, it is possible to provide a side brake device which can be configured simply and inexpensively.

The differential case 10 is formed by connecting an inner case 10a and an outer case 10b which are juxtaposed in the axial direction.
The pressure plate 18 is fitted on the outer case 10b, and the outer case 10b receives a pressing force acting on the brake disk 17 and the pressure plate 18 via the operating mechanism B, that is, a receiver for receiving the pressed member 23. The portion C is formed so that its receiving surface is located on an extension of the mating surface of the case. As an assembling procedure of the side brake device A, first, the four brake disks 17 and the three pressure plates 18 disposed therebetween are fitted to the boss member 16 and the stopper ring 19 is attached. The boss ASSY is prepared in advance, and the boss ASSY is inserted into the differential shaft 12. Next, the remaining one pressure plate 18 is fitted to the inner case 10a, and then the pressed member 23 is fitted. When the overlapping arrangement of the brake disc 17 and the pressure plate 18 is opposite to each other, the order is one pressure plate 18, boss ASSY, and the pressed member 23.
