    摘要: Brake mechanisms (33) that apply braking to rotations of left and right rotational shafts (25) each include a projecting part (40) that faces a partition wall (15A) of a brake case (15) and projects radially inward from an inner diameter side of a piston (37), an engaging member (41) that is arranged in the inner diameter side of the piston (37) in a state of being movably engaged with the projecting part (40) by a predetermined dimension in the left-right direction, and a pin member (42) that is provided between the partition wall (15A) of the brake case (15) and the engaging member (41). A frictional resistance between the pin member (42) and the partition wall (15A) is set to a value smaller than a pressing force of the piston (37) at the braking. The projecting part (40) is provided with an engaging member insertion groove (40A) that the pin member (42) penetrates in the left-right direction, and the engaging member (41) is movably engaged with the projecting part (40) in the left-right direction.

    摘要: Friction disks, such as rotors and stators (40), including floating wear liners (50) are disclosed. The friction disks may include a core (48) and a floating wear liner (50) configured to contact a contact surface (306) of the core. The cores may include a retention ring (244) that is substantially concentric with the core and extends axially beyond the plane of the contact surface. The retention ring (244) may radially constrain the floating wear liner in a position aligned with the contact surface to provide frictional contact with the core during braking.

    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).
