A hand-propelled, self-driving, traveling machine that includes a clutch which enables transmission between a wheel and a transmission shaft. The clutch provides a drive state in which the transmission shaft drives the wheel to rotate and an unlocked state in which the wheel is rotatable relative to the transmission shaft. The clutch includes a driving member, combined with the transmission shaft, a movable pin, movable between a locked position in which the clutch is in the drive state and an unlocked position in which the clutch is in the unlocked state, a transmission member connected to the wheel, a movable friction member provided with a limiting slot, where the movable pin is partially disposed in the limiting slot, and a fixed friction member that is fixed to the chassis and that is in a frictional contact with the movable friction member.

The present invention is directed to a string trimmer having a blower feature incorporated therein. The string trimmer has a cutting head for holding a spool with cutting line. The cutting line is rotated at high speed to cut grass and other vegetation. The cutting head also includes a fan for generating an airflow to act as a blower. The string trimmer can be operated in two modes. In a first mode, both the fan and the spool housing are engaged with the motor so that the rotation of the spool housing performs a cutting operation. In a second mode, the motor engages only the fan to blow air, and the spool housing is disengaged so no cutting operation is performed.

A shifting device for a transmission is disclosed. The shifting device comprises a transmission shaft, a shift gear being mounted thereon, wherein the shift gear is configured with a connecting hub which is axially displaceable relative to the transmission shaft, wherein the connecting hub has an internal toothing in engagement with an external toothing of the transmission shaft, so that the shift gear is drive-connected to the transmission shaft in an axially displaceable manner therewith. A latching device is further provided, the shift gear being axially displaceable thereby into a plurality of latching positions. The latching device comprises a spring-pretensioned setting pin displaceably mounted radially to the transmission shaft and in engagement with a setting shaft rotatably mounted in the transmission shaft, such that the setting shaft and the setting pin can be brought out of an unlocked position into a locked position and vice-versa by rotating the setting shaft.

A belt drive system includes a driving wheel, a driven wheel and a drive belt. A first and a second drive belt tensioning mechanism are included. When a first drive member rotates, it moves relative to a first mounting seat and along an axial direction of the first drive member to drive the first tensioning device to move relative to the housing. When a second drive member rotates, it drives the second tensioning device to move relative to the second mounting seat. A related automatic walking robot includes a housing, a road wheel set rotatably arranged on the housing, and a walking motor arranged on the housing for driving the road wheel set.

A switching device for a transmission have a first and a second transmission housing portion. The switching device comprises a shift collar, a shift fork which engages in the shift collar, a control actuator which is arranged in the first transmission housing portion and an actuator rod which is connected at one end to the control actuator and at the other end to the shift fork. The actuator rod is supported in a first guiding hole which is formed in the first transmission housing portion. It is proposed that a second guiding hole which is formed in the first transmission housing portion parallel with the first guiding hole be formed and a guide rod which is orientated parallel with the actuator rod be provided and be connected at one end to the shift fork and at the other end be supported in the second guiding hole.
