A shifter assembly is used for selecting one of a plurality of gears of a transmission for a vehicle. The assembly includes a housing defining a shift pattern having first and second gates defining first and second shift positions, respectively. A lever is selectively movable into and out of the first and second shift positions within each of the first and second gates. A blocking system is transitionable between a first state which opens the first gate and closes at least a portion of the second gate and a second state which opens the second gate and closes at least a portion of the first gate. A knob is coupled to the lever and is rotatable between first and second positions and communicates with the blocking system to cause the transition of the blocking system between the first and second states when in the first and second positions, respectively.

An electronic gear shifter is described herein that provides tactile feedback imitating the tactile feedback generated by a manual transmission shifter. The shifter includes a tactile feedback mechanism having a base, a pivot through the base, one or more springs coupled to the base, and first and second detents. The base rotates about the pivot, whereas the springs resist rotations of the base from, and return the base to, and equilibrium position. The first detent resists rotation of the base from the equilibrium position. The second detent resists further rotation of the base past the first detent and away from the equilibrium position. Rotation of the base past the first and second detents imitates manual transmission tactile feedback, and rotation of the base past the second detent also closes one or more of the electronic switches.

In a shift lever device, a gate pin of a lever is guided by a gate groove of a gate plate, and a detent pin of the lever is abutted on a detent face of a detent block due to an urging force. A sensor mechanism detects a shift position of the lever. The gate plate, the detent block, and the sensor mechanism are disposed at a lower side of the lever, the gate plate and the detent block are disposed at a rear side of the lever, and the sensor mechanism is disposed at a front side of the gate plate and the detent block. This thereby enables a reduction in size of the shift lever device in an up-down direction.

In a shift lever device, a lever moves an operation member when the lever is rotationally operated in a front-rear direction, and the lever rotates a select link such that the select link moves the operation member when the lever is rotation operated in a left-right direction. The position of the operation member is detected to detect a shift position of the lever. When the lever is rotation operated in the front-rear direction, the lever therefore moves the operation member without being through the select link, thereby enabling the precision with which the shift position of the lever in the front-rear direction is detected to be raised.

A mechanical creeper mode selection system for a transmission of a work vehicle is provided, in which the transmission includes one or more range modes having one or more range mode shift mechanisms each driven by an electrohydraulic circuit. The system includes a creeper mode selection lever movable by an operator to select a creeper gear range. The system also includes a sensor that observes a position of the creeper mode selection lever and generates sensor signals based thereon. The system includes a controller that processes the sensor data to determine a movement of the creeper mode selection lever and outputs one or more control signals to the electrohydraulic circuit to position the one or more range mode shift mechanisms in a range neutral mode based on the movement of the creeper mode selection lever.

A compound transmission shift mechanism is disclosed. The shift mechanism includes a plurality of gears configured on at least one transmission shaft with at least one synchronizer configured to engage at least two of the plurality of gears. The shift mechanism includes a control system configured to engage and position the synchronizer into alignment with the at least two of the plurality of gears. Additionally, the shift mechanism includes at least one damping assembly configured on the control system and operatively connected to the synchronizer.

A gear selector comprising a gate pattern and a gear lever arranged to be moveable within the gate pattern, the gate pattern comprising: a high range gate sub-pattern comprising one or more high range gear planes for moving the gear lever into to select a high range gear; a low range gate sub-pattern comprising one or more low range gear planes for moving the gear lever into to select a low range gear; a neutral plane extending transversely with respect to the high and low range gear planes; and a force profile arranged to urge the gear lever when in the neutral plane toward a resting position in one of the one or more high range gear planes, the force profile comprising a first interference arranged to divide the high range gate sub-pattern from the low range gate sub-pattern, wherein the gear lever is moveable past the first interference from the high range gate sub-pattern to the low range gate sub-pattern when a first predefined action is performed by an operator moving the gear lever.

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.
