Abstract:
A hand-propelled self-driving traveling machine (100) comprises: a clutch (50a) enabling transmission between wheels (30) and a transmission shaft (51), the clutch having a drive state in which the transmission shaft drives the wheels to rotate and a disengaged state in which the wheels rotate relative to the transmission shaft. The clutch comprises: a drive member (57) combined with the transmission shaft, the drive member and the transmission shaft rotating synchronously; a movable pin (52) moving, relative to the drive member, between an engaged position enabling the clutch to be in the drive state and a disengaged position enabling the clutch to be in the disengaged state; a transmission member (56) connected to the wheels and driving the wheels to rotate; a movable friction member (53) formed with a position-limiting recess (531), a portion of the movable pin being located in the position-limiting recess, and the movable pin and the movable friction member rotating synchronously; and a fixed friction member (55) fixed to a chassis (10) or formed as a portion of the chassis, the fixed friction member and the movable friction member being in frictional contact. The clutch of the hand-propelled self-driving traveling machine is highly reliable.
