摘要： A shifting device for a positively engaging clutch having complementary first and second positively engaging coupling elements includes a housing and an actuator rod which is axially movable within the housing by means of an associated rod actuating mechanism. A clutch shift fork for engagement with the first coupling element is mounted on the actuator rod for axial movement of the first coupling element into and out of engagement with the second coupling element in response to axial movement of the actuator rod. The clutch shift fork is mounted on the actuator rod by a threaded connector such that the clutch shift fork is axially movable on the actuator rod. Thus conveniently the axial position of the clutch fork on the shaft may be altered by rotating the shaft relative to the clutch fork for accurate positioning of the clutch fork relative to the coupling element with which it engages.

摘要： An improved gear shift mechanism for an auger gear drive which uses a hydraulic cylinder or other linear force means to push on one end of a rocker arm. This moves the rocker arm and the gear train between a first gear set and a second gear set. A biasing means is applied directly to the rocker arm by a spring or other device. The design eliminates adjustable linkages and the need adjustments in the field and allows for use of a simpler hydraulic cylinder than found in the prior art.

摘要： A double-guidance shift fork transmission box, including a shift fork box body, wherein a shift fork transmission structure and two parallel guide shafts are mounted on the body; a transmission sliding block component is arranged between the guide shafts and can freely slide along them, and the component is connected to the transmission structure. For a conventional shift fork transmission structure having no or one guide shaft, the transmission sliding block component, in the motion process, is affected by thrust of the power output shaft and motion resistance of the shift fork transmission structure only, so that mechanical transmission efficacy and mechanical efficiency of the shift fork and the shift fork box are improved, and stress of the transmission sliding block component on non-axial direction of the guide shaft is eliminated; and thrust generated from the power output shaft is transmitted onto the shift fork transmission structure without loss.

摘要： A dual shift fork includes a sliding fork and a rotary fork rotatably connected to the sliding fork. A pair of pad members are disposed on an inner side of both ends of the sliding fork. A sleeve disposed at an inner side of the sliding fork and contacting the pad members. The pad members are simultaneously engaged with the sliding fork and the rotary fork at an inner side of both ends of the rotary fork. The rotary fork rotates at a predetermined angle with respect to the sliding fork as the sleeve moves independently from the sliding fork.
