摘要: There are provided a rotational shaft provided in a spindle, a wheel mounting cylinder which is mounted through wheel support bearings on an outer peripheral side of the spindle, and a planetary gear reduction mechanism for decelerating rotation of the rotational shaft, which is transmitted to the wheel mounting cylinder. A carrier forming a part of the planetary gear reduction mechanism is mounted in a non-rotating state on an open end side of the spindle. A cylindrical coupling member is provided between an open side of the spindle and the carrier. An oil guide path is formed between a one-side end surface of each of planetary gears and an opposing surface portion of a cylindrical coupling member for guiding lubricant oil ejected from a meshing part therebetween to a planetary gear bearing.

摘要: A wheel mounting cylinder (18) is rotatably provided on an outer peripheral side of an axle housing (12) through wheel support bearings (20, 21). A wet brake (45) is provided between the axle housing (12) and the wheel mounting cylinder (18) for applying a braking force to rotation of the wheel mounting cylinder (18). A seal mechanism (55) is provided between the wet brake (45) and the wheel support bearing (20) for keeping a cooling liquid (50) of the wet brake (45) in a sealed state to lubricant oil (100) in the wheel mounting cylinder (18). A foreign-object trapping portion (58, 62) is provided between the wheel support bearing (20) and the seal mechanism (55) for trapping foreign objects flowing from the seal mechanism (55) toward the wheel support bearing (20).

摘要: A wheel drive motor (18) is disposed at the inner peripheral side of a spindle (15) for a wheel (12), and rotation of a shaft (19) connected to a rotational shaft (18B) of the wheel drive motor is decelerated by a reduction gear (20). An axial intermediate portion (19A) of the shaft (19) is supported by a shaft bearing (44) provided between a sleeve (41) and a retainer (42). On the other hand, a spindle side oil supplying passage (48) is provided in the top portion of the spindle (15) and a retainer side oil supplying passage (49) is provided in the retainer (42). At rotation of the wheel (12), lubricant oil (G) scattered on the upper surface of the spindle (15) is supplied to the shaft bearing (44) through the spindle side oil supplying passage (48) and the retainer side oil supplying passage (49).
