Abstract:
A transmission assembly for a self-propelled machine includes a transmission housing fitted with an input shaft and an output shaft, a so-called drive shaft linked to the input shaft by an endless belt transmission and, arranged between the drive shaft and the output shaft, transmission elements including a control mechanism for reversing the rotational drive direction of the output shaft, and a clutch control mechanism, the direction reversing and clutch controls carried by the housing being mounted respectively movable, one between at least three positions: a neutral position, a forward position and a reverse position, the other between at least an engaged position and a disengaged position. The direction reversing control forms, in the neutral position, an element for blocking the clutch control in the disengaged position, and the clutch control forms, in the engaged position, an element for locking the direction reversing control in the forward or reverse position.
Abstract:
An exemplary transmission may have a reverse shift rail and a locking mechanism to ensure that the reverse shift rail stops in a neutral position when disengaging from the other gear range. The reverse shift rail may be configured to move axially in a first direction to place the transmission in a drive gear, and in a second direction for a reverse gear. The transmission may also include a rail selector configured to engage with the reverse shift rail, and a reverse inhibitor configured to selectively dampen the reverse shift rail from moving in the second direction. An exemplary locking mechanism may include a main body and an arm extending from the main body. When the reverse shift rail disengages from the drive gear, the arm may be configured to contact the reverse inhibitor to substantially inhibit the movement of the reverse shift rail in the second direction.

Abstract:
A transmission power switch device assembled with rotary shaft has a simplified structure and provides power transmission and switching effect. The transmission power switch device includes a rotary shaft connected with a power source. On the rotary shaft are disposed a first drive mechanism, a second drive mechanism and a brake device rotatable with the rotary shaft. The brake device is movable on the rotary shaft to selectively brake the first drive mechanism or the second drive mechanism so as to transmit power to an output shaft.
Abstract:
A drive has a drive source and a continuously variable transmission, with an outgoing shaft having a first gear wheel. A clutch is present between the drive source and the ingoing shaft. The outgoing shaft of the transmission is connected to a gear wheel connected to a differential via a drive line for driving forwards. The drive line has an intermediate shaft with thereon a second gear wheel, which is interlocked with the first gear wheel and the third gear wheel, which is interlocked with the gear wheel. For reversing, the drive line can be interrupted by means of a disengagement and the drive is provided with a further drive line between the gear wheel that is connected to the differential and the outgoing shaft of the transmission.
Abstract:
In a changing system in a manual transmission in which a reverse idling gear is slid and meshed simultaneously with a first reverse gear secured to one of a main shaft and a counter shaft and with a second reverse gear mounted on a sleeve of a preselected synchronizing mechanism mounted on the other of the main shaft and the counter shaft, thereby establishing a reverse speed stage, an interlock plate is formed into a shape for inhibiting the movement of a preselected shifting piece in the same direction as a direction of sliding of the reverse idling gear, when a shifting arm having a drive portion engaged with a reverse shifting piece is turned for shifting to establish a reverse speed stage. Thus, it is possible to inhibit the movement of the sleeve of the preselected synchronizing mechanism, when the reverse speed stage is to be established.
Abstract:
A positioning means for a reverse shifting fork includes a toggle spring for biasing the reverse shifting fork toward one of a reverse position shown by a solid line and a neutral position shown by a dashed line with a dead point set as a boundary between the reverse position and the neutral position, and a stopper pin for stopping the reverse shifting fork in the reverse position and the neutral position against a biasing force of the toggle spring. The toggle spring is a torsional coil spring and is compressed so that a biasing force is generated in a direction to move opposite ends of the spring connected respectively to the reverse shifting fork holder and the reverse shifting fork away from each other, and the distance between the opposite ends is smallest in the dead point.
Abstract:
A reverse shift device of a manual transmission is disclosed to reduce the total length of the transmission, improve shift feeling and decrease noise by excluding a reverse idler gear that rotates, while being meshed between input and output axles, the device comprising: an idle axle fixed at a shift case; and an idle synchronizer installed at the idle axle for switching a state of conveying the rotational force of an input axle to an output axle at the time of forward-reverse shifts.
Abstract:
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.
