Claims

[Claims for Utility Model Registration] (1) A clutch member movable between a coupling position and a coupling release position between an axle-side member and a wheel-side housing, a pressure chamber and a sealed chamber formed in the housing, and A moving member that moves the clutch member to either a connected position or a disconnected position by moving by supplying fluid pressure to a pressure chamber that partitions a pressure chamber and a sealed chamber, and a moving member that moves the clutch member to a connected position by stopping or releasing the pressure supply. Alternatively, a biasing member that moves to the other side of the connection release position, a pressure source that supplies pressure to the pressure chamber, and a pressure switch that stops this pressure supply at a predetermined pressure and increases this stop pressure in accordance with a rise in temperature. The hub clutch is characterized by: (2) A clutch member movable between a coupling position and a coupling release position between the axle-side member and the wheel-side housing, a pressure chamber and a sealed chamber formed in the housing, and a partition between the pressure chamber and the sealed chamber. a moving member that moves the clutch member to one of the engaged position or the disengaged position by supplying fluid pressure to the pressure chamber; a biasing member that moves the clutch member to the other of the engaged position or the disengaged position; A pressure source that supplies pressure to the chamber, a pressure sensor that detects the supply pressure, a temperature sensor that detects the temperature, and signals from these sensors are input to stop the pressure supply from the pressure source at a predetermined pressure. A hub clutch characterized by comprising a controller that increases this stopping pressure in accordance with a rise in outside temperature.
