A transmission parking system is provided. The system includes a parking gear and a parking rod that is connected with the parking gear. Additionally, a parking lever has a first end that is connected with the parking rod and the parking lever is installed rotatably around a control shaft. A detent return spring is wound around an exterior circumference of the control shaft, supports the parking lever, and provides elastic force to rotate the parking lever and return to an original position. A control lever is installed rotatably around the control shaft and is installed at an exterior side of the parking lever to allow user operation. A neutral state maintaining lock and release device is connected with the control lever and is changed to a neutral state lock or a neutral state release based on operation of the control lever.

A shift-by-wire system physically prevents shifting to the R/N/D gear position and shifting to the P gear position from being simultaneously performed. The shift-by-wire system includes a body configured to have a Hall sensor provided therein, a knob installed so as to be rotatable around an axis of the body, a button assembly moving in an axial direction of the body and having a magnet provided to sense rotated and moved states thereof using the Hall sensor and rotate together with the knob, and a concurrent operation limiting unit to mechanically limit movement of the button assembly in a state in which the knob is manipulated so as to be rotated, and to mechanically limit rotation of the knob in a state in which the button assembly is manipulated so as to be moved.

An automatic transmission shifter mechanism that is selectable between an automatic transmission mode and a manual shifting mode, including a shifter assembly configured to move in a first range of movement to be positioned in the automatic transmission mode, and to move in a second range of movement to selectively shift gears up and down in the manual shifting mode, a first sensor configured to sense that the shifter assembly is in the automatic transmission mode in response to the shifter assembly being in the first range of movement, and at least a second sensor configured to sense gear changes in the manual shifting mode, wherein the shifter assembly is configured to be selectively moved laterally from the first range of movement to the second range of movement when in a drive mode in the first range of movement.

An operation device provided in an operator's seat area of a working vehicle, to operate a front loader attached to a vehicle body of the working vehicle includes a lever shaft extending to the operator's seat area; a grip portion provided at a distal end portion of the lever shaft; and a plurality of operation switches provided at the grip portion, to cause the working vehicle to execute various actions. The operation switches include a shuttle changeover switch to switch between forward travel and backward travel of the working vehicle, and a shuttle restraint switch to restrain the switching with the shuttle changeover switch and cancel the restraint.

To curb temperature rises in a control device for a supercharger and extend the life of the control device for the supercharger, a work vehicle includes a variable geometry supercharger with variable boost pressure, and a working device driven by pressure oil discharged from a working hydraulic pump, the work vehicle further including: a supercharger control device adapted to control the supercharger; a temperature detection device adapted to detect temperature of the supercharger control device; and a main control device adapted to limit at least one of maximum rotational speed of an engine and maximum vehicle speed of the work vehicle in case the temperature of the supercharger control device is above a predetermined temperature as compared to case the temperature of the supercharger control device is below the predetermined temperature.

Torque is transmitted from an electric motor to an output unit through different gear trains depending on direction of rotation of the electric motor. The drive unit includes an electric motor, a first gear train, a second gear train, a third gear train, and a moving mechanism. The first gear train includes a first drive gear, a first driven gear, and a clutch member. The clutch member moves inside the first driven gear and receives torque transmitted from the first driven gear. The second gear train transmits to an output unit the torque transmitted from the first gear train. The third gear train transmits to the output unit the torque transmitted from the first gear train. The moving mechanism axially moves the clutch member toward the second drive gear when the electric motor is forwardly rotated and toward the third drive gear when the electric motor is reversely rotated.

An interrocker assembly for a transmission includes at least two shift forks for actuating gears in the transmission, each of the at least two shift forks being pivotal and having an end offset relative to each other, at least two actuators cooperating with the at least two shift forks, one of the at least two actuators cooperating with one of the at least two shift forks, and an interrocker being pivotally movable and cooperating with each of the at least two shift forks to securely prevent two gears from being engaged at the same time.

The present disclosure relates to a shifting apparatus for a vehicle which includes a transmission realizing series of multi shift stages so that shift stages are sequentially increased as shift ratios are decreased. The shifting apparatus may include a shift limit means designating a lowest shift stage having a largest shift ratio to a shift stage for climbing and limiting so that a driver may select the shift stage for climbing in an only case that the vehicle satisfies a predetermined climbing condition; a gradient angle sensor for measuring a climb gradient of the vehicle; a vehicle speed sensor for measuring a vehicle speed; and a controller determining the climbing condition based on signals of the gradient angle sensor and the vehicle speed sensor so as to control the shift limit means.

A control method and system for preventing misoperation of a shift lever of a vehicle are provided. In particular, when a driver manipulates the shift lever to select an automatic transmission mode or a manual transmission mode, shifting into an unintended mode attributable to misoperation is prevented. Therefore, the control method and system improve reliability in manipulating the shift lever and provide a safe driving environment to a driver.

A device and method for preventing inadvertent selection of a parking lock function in a 2-ratio transmission. Here, the shift positions of the transmission and the parking lock function thereof can be selected by way of a shift drum. A mechanically acting apparatus is provided which, in the event of rotation of the shift drum in a first direction of rotation, blocks the selection of a parking lock position of the shift drum, subsequently, in the event of rotation of the shift drum in a second direction of rotation opposite to the first direction of rotation, releases the blocking, and subsequently, in the first direction of rotation opposite to the second direction of rotation, permits selection of the parking lock position. The device does not require a separate parking lock wheel.
