A position detection device includes a magnetic detection element that is positioned radially outside a first clutch component portion and a second clutch component portion of a dog clutch around an axis. The magnetic detection element is provided between a first magnetic flux path portion and a second magnetic flux path portion. The magnetic detection element outputs a sensor signal indicating the direction of a magnetic flux passing between the first magnetic flux path portion and the second magnetic flux path portion. The magnetic detection element outputs a sensor signal indicating a position relationship between the first clutch component portion concerning a first hole portion as well as a first tooth portion and the second clutch component portion concerning the second hole portion as well as the second tooth portion, based on changes in magnetic flux directions depending on the position relationship in a rotation direction around the axis.

The invention relates to a transmission (2) for a wheeled vehicle, comprising a drive member (3), a rotatable driven member (5) in permanent engagement with the drive member (3), a wheel drive shaft and, disposed between the wheel drive shaft and the driven member (5), a clutch mechanism (8), comprising at least one axially movable part on the wheel drive shaft between a position separated from the driven member (5), corresponding to an activated state of the clutch mechanism (8), and a position close to the driven member (5), corresponding to a deactivated state of the clutch mechanism (8), which is activated by rotating the driven member (5) in a first direction of rotation, referred to as forward drive, and can be deactivated by rotating the driven member (5) in a second direction of rotation opposite to said first direction of rotation, referred to as reverse drive, said part (9) of the clutch mechanism (8) which, in the deactivated state of the clutch mechanism (8), is disposed in a position close to the driven member (5), is, in said position, limited in its axial movement in the direction of a separation from the driven member (5) in the reverse drive state of the driven member (5).

A lay-shaft assembly for use in a vehicle transmission includes a clutching mechanism with a synchronization assembly arranged for synchronizing rotation of a driven gearwheel with a first gearwheel or a second gearwheel. The first and second gearwheels extend adjacently with respect to each other along the central axis, and the synchronizing assembly is positioned between adjacent respective outer circumferential surfaces of the adjacent first and second gearwheels and the sleeve. A ring-shaped biasing means support and a complementary biasing means insert for placing onto the ring shaped biasing means support.

A switching device for a drivetrain of a motor vehicleincludes a housing in which a first and a second driveshaft are rotatably mounted. The first and second driveshafts are arranged coaxially with one another so that they have a common rotation axis; The switching device further including switchable clutch device arranged between the first and the second driveshaft. The clutch device is transferrable into a disengaged open switched position, in which the first driveshaft is freely rotatable relative to the second driveshaft, and into an engaged switched position, in which the first driveshaft is connected to the second driveshaft via the clutch device for conjoint rotation. The control element is formed by a sliding sleeve, with an annular space being formed between each of the clutch elements, the corresponding drive shaft and the control element. The control element is arranged displaceably relative to the clutch element over a delimited axial path of movement, such that the volume of the annular space is variable.

A vehicle steering system and a vehicle are provided. The vehicle steering system includes a steering shaft and a steering transmission shaft. The steering shaft or the steering transmission shaft includes a first shaft section and a second shaft section. A clutch mechanism is arranged between the first shaft section and the second shaft section. In an engaging state, a transmission connection is established between the first shaft section and the second shaft section and in this case, a controller determines that the vehicle enters a driving mode. In a disengaging state, the transmission connection between the first shaft section and the second shaft section is disconnected, and in this case, the control modulecontroller determines that the vehicle enters a game mode.

A gatebox system for delivering fire retardant fluid from a firefighting aircraft. A first and second gate opening are formed through a lower portion of a gatebox. The gates are hingedly connected along edges of the openings. One or two drive shafts in the gatebox are rotatable in gates-closing and gates-opening directions. Crank arms are fixed to the drive shafts and coupled to the gates by connecting links, which define an over-center geometry while the gates are at a closed position, such that weight of the fluid on the first gate induces torque on the drive shaft in the gates-closing direction. Rotation of the drive shafts in the gates-opening direction enables control of the fluid flow from the hopper according to an angular position of the drive shaft.
