摘要： A transmission device for a work vehicle includes an auxiliary transmission including forward gear shift stages for the work vehicle to move forward and a reverse gear shift stage for the work vehicle to move backward. The forward gear shift stages include a low-speed gear shift stage with a largest gear ratio among the plurality of forward gear shift stages, and a medium-speed gear shift stage with a gear ratio closest to a gear ratio of the reverse gear shift stage among the forward gear shift stages.

摘要： In a jaw-type gearshift for an at least two-stage gearbox, which is in particular electromotively driven, a ring-shaped shifting gate with a sliding block guide is provided, which has axially protruding shifting jaws and is in shifting contact by means of a shifting finger arranged on the sliding sleeve and engaging in the sliding block guide. In a method for shifting the jaw-type gearshift, the shifting jaws are coupled into corresponding receptacles of the gear wheels in that the shifting gate is moved axially relative to the sliding sleeve and the rise of the sliding block guide.

摘要： A shift drum has a recess which controls a fork to move one of two cooperating coaxially arranged gears for transmitting torque in a power train of a vehicle. The recess includes a straight section, which upon rotation of the shift drum does not move the fork either to the left or the right, and at least one ramp which does move the fork in one direction (i.e., to the left or the right). The ramp is more complex than a single line, such as having a first portion at a first right-shift portion ramp angle β and a second portion at a second right-shift portion ramp angle γ, perhaps with the intersection between the first right-shift portion ramp angle β and the second right-shift portion ramp angle γ being at the mid-line defined by the straight section of the recess.

摘要： A hand-held power tool includes: a shiftable transmission for driving a drive shaft, which transmission is situated in a gear housing and is shiftable at least between a first gear and a second gear via a shifting member; and a pivotably supported actuating element, which is configured as a bistable spring element and situated, at least in sections, in the area between the shifting member and the gear housing, is associated with the shifting member. The bistable spring element is actuatable for the gear shifting, and assumes a stable shift position in at least one shift position of the shifting member associated with the first or second gear, and assumes an unstable position in an intermediate position of the shifting member which is situated between shift positions of the shifting member associated with the first and second gears.

摘要： The invention is to suppress the increase of axial lengths of each input shaft and each output shaft and increase the number of gear shift stages. A transmission device transmits a driving force of a crankshaft from a first transmission to a drive wheel side through a second transmission. The first transmission is provided with a first countershaft to which the driving force from the crankshaft is transmitted, and a first drive shaft to which the driving force of the first countershaft is transmitted. The second transmission is provided with a second countershaft to which the driving force of the first drive shaft is transmitted, and a second drive shaft to which the driving force of the second countershaft is transmitted and which transmits the driving force to the drive wheel side. The first and second transmissions are disposed side by side in a front/rear direction. Each of the first and second transmissions is set to have a plurality of gear shift stages.

摘要： A gear-shifting device for a vehicle is provided and includes a guide body that has a first end portion connected to a control shaft, installed so that a second end portion is rotated at the first end portion as an axis in a rotational displacement that corresponds to a selecting path to perform a selecting operation, and installed to be moved in a substantially straight displacement that corresponds to a shifting path along an axis direction of the first end portion to perform a shifting operation. A guide unit is disposed to distinguish each shifting path on the selecting path in which the second end portion of the guide body is rotated and is configured to guide the second end portion of the guide body to be movable along the shifting path.

摘要： A control device of a twin-clutch transmission includes a gear operation mechanism driven by a single actuator mechanism . The gear operation mechanism performs a selection operation to select a synchromesh unit to operate from a plurality of synchromesh units and a shift operation to drive the selected synchromesh unit to an engagement position (in-gear position) corresponding to a shift position. In the control device, based on a deceleration rate of a vehicle, a determination is made to allow or disallow continuation of the shift operation at a change of a shift position to a target shift position. When a determination is made to disallow continuation of the shift operation, only the selection operation is performed, and the shift operation is prohibited. When a determination is made to allow continuation of the shift operation, the shift operation is allowed.

摘要： A changing system in a manual transmission is provided. An interlock plate is mounted on a shift-selecting shaft capable of being moved axially in response to a selecting operation and turned about an axis in response to a shifting operation, so that the interlock plate cannot be turned about an axis of the shift-selecting shaft. The interlock plate has a pair of side plate portions which are provided at locations spaced apart from each other in an axial direction of the shift-selecting shaft and through which the shift-selecting shaft extends. A shifting arm disposed between the side plate portions is fixed to the shift-selecting shaft. In such changing system, the shifting arm and an interlock member operatively connected to the shifting arm are interposed between the side plate portions of the interlock plate. Thus, the shifting arm can be used commonly in manual transmissions, in despite of a difference in number of forward speed stages between the manual transmissions, thereby providing a reduction in cost and avoiding an increase in weight due to a variation in number of forward speed stages.
