A medical device drive system can include a rotational input, a coupling member engaged with the rotational input, a first gear having an engagement feature sized and shaped to engage with the coupling member, and a second gear coupled with the first gear, the second gear coupled to a movable element. The system can have a first system state and a second system state. In the first system state the coupling member is not engaged with the engagement feature and the first gear rotates without moving the coupling member. In the second system state the coupling member is engaged with the engagement feature of the first gear and rotation of the rotational input turns the coupling member, the first gear, and the second gear to move the movable element.

The invention relates to a gearbox system for a vehicle having: an automated manual gearbox; a gearbox control device designed to control the automated manual gearbox; a monostable toggle switch which can be operated by a user, in particular a driver, and is movable in at least, in particular exactly, two deflection directions and by means of which a plurality of driving ranges of the gearbox control device can be selected by the user; and a visual device which displays or can display graphically a gearshift diagram with driving ranges selectable by the toggle switch. The gearbox control device has a further driving range which cannot be selected by means of the toggle switch but can be exited by moving the toggle switch in at least one of the two deflection directions. The visual device has at least one display designed to display a symbol which indicates the at least one deflection direction of the toggle switch by means of which the further driving range can be exited. The gearbox control device is also designed to control the at least one display such that the symbol is only displayed when the further driving range is selected.

A system and method are described to help ensure that gears contained within the transmission system are shifted to the correct position before the user can apply the throttle. An electronic control unit (ECU) is connected to a shift position sensor that measures a position of a shifting axle within the engine. If the shift position sensor provides measurement data indicating that the shifting assembly is rotationally positioned to engage a specific gear, the ECU allows the user actuated throttle input to control the throttle level of the engine. If the shift position sensor provides measurement data indicating that the shifting assembly is rotationally positioned in between positions that actuate specific gears (also known as a “dead zone”), the ECU prevents the user actuated throttle input from controlling the throttle level of the engine.

A reaction cable differential interlock system can include a differential lock lever, a shift lever, a mode select lever, a linkage mechanism, and a single cable. The differential lock lever can be configured to be movably mounted on a differential gear assembly and connected to a differential lock collar of the differential gear assembly. The shift lever can be movable between a plurality of transmission mode positions and the mode select lever can be movable between a plurality of differential mode positions. The linkage mechanism can be coupled to the shift lever and the mode select lever, and the single cable can extend from the linkage mechanism to the differential lock lever.

A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. A controller controls the shift actuator utilizing an actuating pulse and an opposing pulse.

An L-shaped bracket (151) is fixed to a top end portion of a rack shaft (141) of a selecting actuator (133) of a transmission actuator unit (131) through a rotatable joint (152). An actuator housing (161) of a shifting actuator (134) is supported on a mounting surface (151a) of the L-shaped bracket (151) so as to be attachable to and detachable from the mounting surface (151a) through a lock mechanism (154) (a lock pin (155) and a lock hole (162a)). The shifting actuator (134) can be mounted with the shifting actuator (134) being reversed 180 degrees.

The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. A shift control circuit operates a shift actuator using a first opposing pulse command and a first actuating pulse command, and releases pressure with shift actuating and opposing volumes of the shift actuator upon determining a shift completion event.

A control unit for an automatic transmission of a vehicle is provided. The vehicle includes a gear selection operating element which allows a user of the vehicle to set different drive positions of the transmission, but not individual gears, by actuating the gear selection operating element. The control unit is configured to determine that a drive position “L” has been set using the gear selection operating element, and in response thereto, the control unit is also configured to provide a graphical user interface on a screen of the vehicle. The user interface allows a manual gear shift of the transmission.
