摘要:
The invention relates to a transmission device for a motor vehicle comprising a plurality of connecting elements that are mounted in an axially movable manner and are each provided with a shift mouthpiece and comprising an actuating device having a control shaft that is mounted in a swiveling and axially movable manner, on which is provided a main control element and at least one secondary control element, the at least one secondary control element having functional regions for a movement in the same direction as well as functional regions for movement in the opposite direction, the at least one secondary control element extending in its neutral position essentially perpendicular to the direction of movement of the connecting elements, and, with respect to this neutral position on the secondary control element and on at least one shift mouthpiece, the particular functional regions for the movement in the same direction being designed with a bent shape and being axially symmetric to the particular, likewise bent functional regions for the movement in the opposite direction, and specifically with respect to a plane that is defined by the axis of rotation of the control shaft and the direction of movement of the connecting element.

A power transmission for a motor vehicle. The transmission includes a plurality of transmission ratio steps defined by pairs of gear carried on parallel shafts, and final output mechanisms for engaging desired transmission ratio steps. The final output mechanisms are operable for controlling the engagement of respective transmission ratio steps to minimize tractive force interruption by allowing rapid gear changes to be effected to reduce the times between shifts of gears. By sensing accelerator pedal position and vehicle speed a new transmission ratio step to be subsequently engaged can be pre-selected while an engaged gear remains engaged.

A four-wheel vehicle drive system for a part-time 4-wheel drive vehicle having a high-speed 2-wheel drive mode, a high-speed 4-wheel drive mode, and a low-speed 4-wheel drive mode. The four-wheel vehicle drive system includes a power receiving gear mechanism receiving power from an engine through a transmission, a rear wheel shaft gear mechanism for transmitting rotating force to rear wheels, the rear wheel shaft gear mechanism having a high speed section and a low speed section, a power transmitting gear mechanism for transmitting power from the power receiving gear mechanism to the rear wheel shaft gear mechanism, a front wheel shaft mechanism for selectively transmitting rotating force to front wheels; and a shift control device connected to the rear wheel shaft gear mechanism and the front wheel shaft mechanism to selectively power-couple the rear wheel shaft gear mechanism to the front wheel shaft gear mechanism and one of the high and low speed sections to the rear wheels.

A transmission shift rail with a control rail 12 and shift fork 30. A pin 26 extends into a translation slot 36 in the shift fork 30 to produce axial movement of the shift fork 30 when the control rail 12 rotates, without translating the shift fork 30 when the control rail 12 translates.

A shifting arrangement for a motor vehicle gearbox has a housing which defines a longitudinal axis. A rod is mounted axially displaceably in relation to the housing and can be coupled to a shifting clutch arrangement. A shift shaft is mounted rotatably in relation to the housing and is oriented transversely with respect to the longitudinal axis. The shift shaft being coupled to the rod by means of a driver device in such a way that the rod is displaced in a first longitudinal direction in the case of a rotation of the shift shaft in a first rotational direction. The driver device is a freewheel driver device which is configured in such a way that the rod is decoupled from the shift shaft in the case of a rotation of the shift shaft in a second rotational direction.

A driving unit for a vehicle includes plural gear sets, plural switching clutches, a lever member, an output shaft, a motor generator, a separating clutch provided for interrupting a force transmission between the output shaft and the motor generator, and a separating shifter supported to be movable in a direction of a selecting movement of the lever member between a first position and a second position. The separating clutch is connected to the separating shifter to operate the separating clutch to be engaged when the separating shifter is located at the first position and to be released when the separating shifter is located at the second position. The lever member is engaged with the separating shifter located at the first position when one of the gear sets for establishing the highest shift stage is selected and operates the separating shifter to move to the second position.

A parking mechanism for a transmission, comprising: a coupling member engageable simultaneously with two gears for different gear positions of the transmission when a change device provided besides a driver's seat is set in a "parking" position.
摘要:
A manual shift transmission having multiple input and output portions is provided with a control having input and output shift rails. A laterally movable control shaft extends axially through cutouts in respective shift rails and carries cams adapted to cooperate with cam follower surfaces on corresponding cutouts to effect rectilinear movement of the shift rails upon rotation of the control shaft. The cams are arranged on the shaft so that the shaft may be positioned to place respective cams in register with the input and output shift rails while all other cams are out of register with the rail cutouts. The shift movement of respective output and input shift rails is overlapped during the rotation of the control shaft to decrease the throw of the shift lever.
