摘要： A spindle drive for a closure element of a motor vehicle. The spindle drive including a drive unit and a spindle-spindle nut transmission and including a spindle and a spindle unit for generating drive movements. The spindle drive including first and second drive sections, including first and second drive connections and configured to move relative to another between a retracted state and mi extended state over an adjustment path along a longitudinal axis of the drive unit. The spindle disposed in the second drive section and is axially fixed relative to the first drive connection, and the spindle nut is disposed in the first drive section and is axially fixed relative to the second drive connection. The spindle drive includes a support sleeve radially surrounding the spindle nut in the extended state and is mounted such that the spindle nut is axially moved relative to the two drive connections.

摘要： A harvesting machine includes a chassis, a ground-engaging mechanism for supporting the chassis, and a tank assembly mounted to the chassis for storing a crop material. The tank assembly includes a retractable door for at least partially covering an opening formed in a top of the tank assembly. A mobile sensor assembly includes a rod and a sensor for detecting a weather condition, such that the rod includes a first end coupled to the retractable door and a second end to which the sensor is coupled. The retractable door is operably moved between an open position and a closed position, and the mobile sensor assembly is rotatably moved between a deployed position and a stowed position as the door is moved between the open and closed positions, respectively.

摘要： Disclosed herein is an apparatus for variable fluid damping. The apparatus comprises a mount. The apparatus also comprises a damper coupled to the mount to apply a damping force in response to movement of the mount. The apparatus further comprises an electrical element positioned to correspond to the damper. The apparatus additionally comprises a rheological fluid disposed in the damper. The rheological fluid changes viscosity in response to a change in an output of the electrical element to change the damping force of the damper. The apparatus also comprises a controller to provide input to the electrical element in response to a normal operating condition or an emergency operating condition.

摘要： Disclosed is an aircraft piston assembly, having: a piston housing fluid port formed in a piston housing; a piston shaft, disposed within the piston housing, configured for translation in either forward or aft directions when fluid is respectively supplied to or removed from the piston housing; a screw shaft, disposed within the piston housing, that includes a first gear that rotates without translation while the piston shaft translates; and a slider, disposed within the piston housing, that includes a second gear, and that is configured for translation without rotation, wherein: the slider moves between a first position where the first gear and the second gear are separated from one another to allow the piston shaft to translate and a second position where the second gear surrounds the first gear so that the first and second gears are engaged with one another and the piston shaft is prevented from translating.

摘要： A dampening system (28) that includes an actuation state and/or a door actuation system that includes a single-use pressurized tank (34). The dampening system or the door actuation system may include a damper (30) and a fluid pressure source (e.g., the single-use pressurized tank (34)) that pressurizes the damper to actuate from a first position to a second position. The pressurization allows the damper to actuate another component, such as a vehicle door (26) that is operably coupled to the damper. A user may shift the damper into the actuation state to actuate the vehicle door open during an emergency, such as when a military vehicle is on its side after an explosion knocks over the vehicle and the vehicle door is too heavy for the user to open without assistance.

摘要： A hydraulic piston actuator, which may be used for an aircraft nacelle assembly, includes a housing, a piston, an end gland, and a bearing ring. The housing is concentrically disposed along an axis. The piston is adapted to axially reciprocate within the housing. The end gland is disposed radially between the housing and the piston. The bearing ring is disposed radially between the end gland and the piston.

摘要： An overhead door frame assembly has a horizontal header connected to tripod legs with splice assemblies. Each tripod leg has two upright columns connected to an upright I-bar. One of the splice assemblies is fastened to each upright column. Hinges pivotally mount an overhead door to the header to allow hydraulic cylinders to move the overhead door to an open position and a closed position.

摘要： An actuator system comprising a rotatable lock mechanism defining a path for an actuator pin as the actuator is expanded and retracted, wherein the lock mechanism defines an entry passage through which the pin enters as the actuator extends, a guide surface along which the pin travels from the entry passage as the actuator retracts, a locking recess into which the pin is guided by the guide surface, and an exit passage into which the pin is guided as it is caused to leave the lock recess by extension of the actuator and subsequent retraction; whereby a detent surface is provided to prevent the pin returning back into the lock recess when the actuator is extended to cause the pin to leave the lock recess; and whereby the lock mechanism provides a sloping engagement surface for the pin, either side of the entry passage.
