A mechanical unlocking mechanism for electronic parking is provided, which comprises a parking cam assembly, a pawl assembly, a parking gear, a pull cord assembly and an actuating assembly. The parking cam assembly comprises a parking guide shaft and a parking cam. The parking cam is sleeved on the parking guide shaft. The outer side of the parking cam is provided with an arc protrusion along a circumferential direction, so that with the rotation of the parking cam, the pawl assembly is in a first position where the parking gear parks in and a second position where the parking gear parks out. One end of the pull cord assembly is connected with the actuating assembly, and the other end of the pull cord assembly is connected with the parking guide shaft. The actuating assembly drives, via the pull cord assembly, the parking guide shaft to translate, thereby driving the pawl to move from the first position to the second position. The mechanical unlocking mechanism according to the present disclosure provides an emergent mechanical unlocking function when the parking motor is powered off, and the driver can perform manual mechanical unlocking in the cab without getting off the vehicle, so it has high safety and good operation comfort.

A stroke sensor includes: a shaft that extends in an axial line direction; a detected body that is fixed to the shaft; a housing that extends along the shaft, that houses the shaft, and that supports the shaft slidably in the axial line direction; and a detection body that detects a movement amount of the detected body which moves in accordance with sliding of the shaft, wherein the shaft includes a plurality of shaft members that are connected to each other in the axial line direction and that are formed of metal, and a slide part that is in contact with an inner wall of the housing and that slides so as to regulate a movement of the shaft in a direction that is crossed with the axial line is provided on each of the plurality of shaft members.

A parking lock includes a locking pawl (2) and an interlocking element (6) arranged on a connecting bar (5) to a selector lever (4). The end of the connecting bar (5) facing away from the interlocking element (6) is articulatedly connected to the selector lever (4). A hydraulically actuatable actuator (10) includes two pistons (11, 12) provided for disengaging the parking lock. During normal operation, a detent device (13), which is actuatable by an electromagnet (13a), locks the first piston (11) in a piston position corresponding to an engaged condition (P_ein) or a disengaged condition (P_aus). Without requiring activating the electromagnet (13a) to release the detent device (13), the parking lock, during normal operation, is manually disengagable with an emergency disengagement device (15) acting upon the second piston (12) and is manually engagable with an emergency engagement device (16) acting upon the detent device (13).

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.

An operation device for a vehicle transmission is configured to include: a base bracket that is fixed to a vehicle body of a vehicle; a slider lever that is slidably supported by the base bracket and includes a shift knob; and a main gear, which is rotatably supported by the base bracket and includes gear teeth at an outer circumferential portion, to which an end portion of a shift wire of the vehicle transmission is connected at a position separated from a gear support shaft of the base bracket, the slider lever including a rack gear that is formed along a sliding direction of the slider lever and is engaged with the gear teeth of the main gear, and gear change of the transmission being performed by causing the main gear to rotate with sliding of the slider lever and pushing and pulling the shift wire.

The invention relates to an actuator having a drive device which drives a drive shaft, a first actuating element which is operatively connected to the drive shaft, a spring element which can be supported on one side on a housing component of the actuator and is supported on the other side on a second actuating element which is configured for stressing the spring element, wherein a rotational element which can be driven by means of the drive shaft and is rotatably mounted is provided. According to the invention, a further actuating element for actuating a switching device is provided, which further actuating element is operatively connected to the first actuating element, and a transmission device with a transmission element is provided between the first actuating element and the actuating element of the switching device.
