摘要： A garden tool power system comprises a motor, a reducer and a transmission shaft. The motor transmits the power to the transmission shaft through the reducer to drive wheels on the transmission shaft to rotate. The reducer comprises a pinion connected to an output end of the motor and a gear engaged with the pinion. The transmission shaft includes left and right shafts connected with each other through a connecting shaft. The gear mounted on the connecting shaft has at least two guiding rods transversely located thereon and two centrifugal blocks located between the guiding rods. Each guiding rod has a spring surrounded therearound and each spring located between two centrifugal blocks has two opposite ends respectively abutted against the corresponding portions of the centrifugal blocks. A fixing sleeve provided on the periphery of the centrifugal blocks is mounted on the transmission shaft and has buckle structures matching with the centrifugal blocks.

摘要： The power equipment such as a lawn mower (10) comprises an internal combustion engine (100) having a plurality of cylinders, an engine control unit (110) for selectively deactivating at least one of the cylinders, a work implement such as a cutting blade (70) connected to the engine in a power transmitting relationship, a clutch (80) provided in a power transmission path between the engine and the work implement, and a central control unit (50) for controlling an operation of a propelling device, the clutch and the engine control unit. The central control unit is configured to operate the engine at a prescribed rotational speed with two or more of the cylinders kept activated when the clutch is engaged and the propelling device is propelling the power equipment forward, and to deactivate at least one of the cylinders when an opening of a throttle valve is below a first prescribed value for a prescribed time period.

摘要： A drive train for driving a working unit of a self-propelled harvester is disclosed. The drive train includes a selectable belt drive with a drive belt, which operationally combines a drive belt pulley and an output belt pulley. The output belt pulley of the belt drive is operationally connected to the working unit via a drive shaft. The drive train comprises a clutch system, combining the functions of a belt clutch and an overload clutch into a single construction unit, with the response characteristic of the overload clutch system being hydraulically adjustable.

摘要： A reducer with a double-clutch structure includes a source power input shaft and a power output shaft. A speed reduction mechanism includes a driving device and a driven device installed on the output shaft. A first clutch device is arranged on the output shaft and is driven by the driven device thereby driving the output shaft. A second clutch device is arranged on the output shaft and is meshed with the driven device to drive the output shaft. A clutch control device operates the first clutch device and the second clutch device simultaneously to move between the engaging position and the disengaging position. The first clutch device engages earlier than the second clutch device and disengages later than the second clutch device. When the clutch control device operates the second clutch device to move axially to an engaging position from a disengaging position, the first clutch device is axially pushed to the engaging position from the disengaging position by the second clutch device.

摘要： The purpose is to provide a working vehicle such that, when a reverse switch coupler is detached, or when a wire connecting a reverse switch to a control device is disconnected, driving of a PTO shaft can be reliably prevented and reliability of the reverse switch can be improved. In a tractor, a reverse switch includes a normally closed type first contact, and a normally open type second contact that is switched in association with the first contact. When an input voltage from the first contact is higher than a set voltage, and when the input voltage from the first contact is lower than the set voltage and an input voltage from the second contact is equal to or lower than the set voltage, a control device controls the actuator such that the PTO clutch is disconnected.

摘要： A clutch for a mower has an electric motor, a drive mechanism connected with the motor and an output mechanism connected with the drive mechanism. The drive mechanism has a cam driven by the motor and a cam follower reciprocating along with the cam. Reciprocation of the cam follower switches the output mechanism between a transmission state and a non-transmission state.

摘要： A speed select shift mechanism for a belt drive assembly to be installed on a shaft capable of shifting between high, low and neutral speeds is disclosed. The shift mechanism includes a shift collar that is enclosed within an enclosure to prevent debris from contacting the inner operations of the shift mechanism and thereby reduce wear and tear of the shift mechanism along with down time for maintenance of the device. The shift mechanism includes a shaft, a first pulley, a shift collar, a second pulley and a shifter. The shift collar further includes dowels that cooperatively engage corresponding apertures on the pulleys.
