Abstract:
A parking brake of a work vehicle has a piston near the wheel relative to an end plate in an axial direction parallel to a rotation axis of the drive shaft to move in the axial direction, a hub between the end plate and the piston in the axial direction to be connected to the drive shaft, a cylinder disposed outwardly from the hub in a radial direction relative to the rotation axis, a disk supported by the hub in an inner space defined by the end plate, the piston, the hub, and the cylinder, a separator supported by the cylinder, next to the disk in the inner space, and moved by the piston in the axial direction, a first passage connecting the inner space and an outer space, and a second passage provided outwardly from the first passage in the radial direction to connect the inner and outer spaces.

Claim (Index 1):
A work vehicle comprising:\n a vehicle body frame; an electric motor supported by the vehicle body frame; a power transmission mechanism including a drive shaft connected to an output shaft of the electric motor, the power transmission mechanism transmitting power generated by the electric motor to a wheel on which a tire is mounted; a supporting member supported by the vehicle body frame, the supporting member rotatably supporting the drive shaft; and a parking brake configured to restrict a rotation of the drive shaft, the parking brake including: an end plate supported by the supporting member; a piston disposed near the wheel relative to the end plate in an axial direction parallel to a rotation axis of the drive shaft, the piston moving in the axial direction; a hub disposed between the end plate and the piston in the axial direction, the hub being connected to the drive shaft; a cylinder disposed outwardly from the hub and the piston in a radial direction relative to the rotation axis; a disk supported by the hub and disposed in an inner space defined by the end plate, the piston, the hub, and the cylinder; a separator plate supported by the cylinder, disposed next to the disk in the inner space, and moved by the piston in the axial direction; a first outlet passage configured to connect the inner space and an outer space; and a second outlet passage provided outwardly from the first outlet passage in the radial direction, the second outlet passage connecting the inner space and an outer space, the first outlet passage being provided between the piston and the hub, the second outlet passage being provided in the cylinder.
