摘要： A multi-directional compliant shifting mechanism for a multi-speed power tool may couple a movable selector to a power transmission system of the tool, for selecting an operational speed of the multi-speed power tool. The complaint shifting mechanism may provide shifting compliance in a first direction in response to movement of the selector in a first direction, and may provide shifting compliance in a second direction in response to movement of the selector in a second direction. In one example, this multi-directional shifting compliance may be provided by interaction of the selector with a camming surface, in combination with a single compression spring. In another example, this multi-directional shifting compliance may be provided by first and second springs, selectively acting to provide compliance in the first and second directions.

摘要： A method for assembling a vehicle transmission shift shaft assembly with a shift shaft having a first diameter, a shift lever fixedly mounted to an end thereof, and a step defining a second diameter smaller than the first diameter along a length thereof. The method includes positioning a seal on the shift shaft to abut the shift lever, and positioning a spacer on the shift shaft to abut the seal. The method further includes positioning a bushing over the spacer, and positioning a retainer clip on the shift shaft adjacent to the step so as to retain the bushing over the spacer.

摘要： A combined machine with selective actuation includes: support frame and ground support; an engine including a drive shaft; a driven shaft connected to the drive shaft by the engine; first and second operating machines connected to the driven shaft; and a set for selectively transmitting motion from the driven shaft to the operating machines. The transmission set includes: first and second belted transmissions operationally connecting the driven shaft to the first or second operating machine; and a movement unit to selectively move the driven shaft from idle to a first or second operating position. In operation, when the driven shaft is in the first operating position, the first belted transmission is under tension, actuating the first operating machine. When it is in the first operating position, the second belted transmission is under tension, actuating the second operating machine. In idle, both belted transmissions are slack, halting both operating machines.
