摘要： A method for operating a robotic joint of a robotic system comprising selectively operating a clutch mechanism of a clutched joint module in an engaged state to cause a quasi-passive elastic actuator to enter an elastic state, the clutched joint module operating about and defining a joint of the robotic system. The method comprising effecting a first rotation of the joint to cause the quasi-passive elastic actuator to store energy during at least a portion of the rotation of the joint. The method comprising effecting a second rotation of the joint and causing the stored energy from the quasi-passive elastic actuator to be released in the form of an augmented torque applied to an output member of the clutched joint module. The method comprising selectively operating the clutch mechanism in a disengaged state to cause the quasi-passive elastic actuator to enter an inelastic state. The method comprising effecting a third rotation of the joint, wherein the quasi-passive elastic actuator facilitates a free swing mode of the clutched joint module and the joint.

摘要： A dog clutch includes a gear (40) mounted on a power transmission shaft (30), first and second dog rings (10, 20), a fork (60), springs (65), and cam grooves (31). The cam grooves (31) each include a first slope surface (36) inclined from the axial direction toward the positive rotation direction as the first slope surface (36) approaches the gear (40) and a second parallel surface (37) parallel to the axial direction. The first dog ring (10) includes first cam protrusions (16) to be engaged with the respective first slope surfaces (36), and the second dog ring (20) includes second cam protrusions (26) to be engaged with the respective second parallel surfaces (37). This structure prevents the dog rings and the fork from coming into contact with each other, thereby avoiding generation of abrasion and increasing the transmission efficiency.

摘要： A work vehicle includes a shaft supported by a cabin and having a center axis. A clutch pedal is supported by the shaft so as to be swingable about the center axis. A control cable includes an outer tube and an inner cable slidably inserted to the outer tube. The control cable is wound on a partition wall of the cabin and has flexibility. The at least one latch member is configured to latch the control cable onto the partition wall. The at least one retain member is configured to restrict the control cable from swelling within a winding region of the partition wall. The outer tube has a first longitudinal end connected to the cabin and a second longitudinal end connected to a clutch housing. The inner cable has a first longitudinal end connected to the clutch pedal and a second longitudinal end connected to the clutch lever.

摘要： An actuating drive, in particular for seat adjustment devices, comprising at least one electric motor, a downstream reduction gear, a coupling device which has a coupling engagement spring that ensures an engaged position of the coupling device during motorized operation and permits a manual disengagement against its coupling force. The coupling device has a coupling lever pivotably mounted in a pivot bearing of a bearing block. The coupling lever is connected at one end of the pivot bearing to a mechanical actuating unit and by which at the other end of the pivot bearing a coupling means can be adjusted to disengage the coupling device. The actuating drive ensures both reliable electrical and reliable manual operation, a high degree of efficiency during electrical operation and simple assembly for a generic actuating drive.

摘要： Provided is a clutch device configured so that different desired torque values can be set without influence between assist torque and slipper torque. A clutch device 100 includes a center clutch 105 holding clutch plates 104 arranged facing friction plates 103 to be rotatably driven by a drive shaft, and a pressure clutch 111. The center clutch 105 includes center-side assist cam surfaces 106a and center-side slipper cam surfaces 106b. The pressure clutch 111 includes pressure-side assist cam surfaces 112a and pressure-side slipper cam surfaces 112b. A contact surface between the center-side assist cam surface 106a and the pressure-side assist cam surface 112a and a contact surface between the center-side slipper cam surface 106b and the pressure-side slipper cam surface 112b are formed at different positions in a radial direction.

摘要： A connect-disconnect assembly for a vehicle drivetrain configured to drive a vehicle with a surface engaging traction member. The connect-disconnect assembly includes a coupler located within a final drive element or gear of a final drive assembly wherein in a first position the coupler does not span a gap between the gear and a transmission drive element of a transmission. In a second position, the coupler does span the gap between the gear and the transmission drive element such that the gear and the transmission drive element are connected. The final drive assembly includes an access port to provide access to a user accessible drive actuator to move the coupler between the first and second positions.

摘要： A sensor assembly for determining a number of rotations of a permanent magnet includes a first sensor. The permanent magnet has an axis of rotation, end surfaces lying in an X-Y plane, a central axis, and exactly two poles. The two poles are disposed in the X-Y plane on mutually opposite sides of the permanent magnet so that the permanent magnet is magnetized diametrically. The first sensor is axially fixed and rotationally displaceable relative to the permanent magnet. The first sensor is disposed at a first distance axially offset from the permanent magnet and at a second distance radially offset from the axis of rotation. The second distance is selected so that a vector sum of a radial flux density and a tangential flux density is not less than a first limit value and does not exceed a second limit value.

摘要： A clutch system for a motor vehicle includes a friction clutch, a ramp system, a driver, and a magnetic clutch. The friction clutch includes a pressure plate, and is arranged for transmitting a torque between a torque admission element and a torque release element. The ramp system is for axially displacing the pressure plate. The ramp system has an input ramp and an output ramp, rotatable relative to the input ramp, for varying an axial extent of the ramp system as a result of a speed differential between the torque admission element and the torque release element. The driver is coupled to the input ramp and supported so as to allow relative rotation on the torque admission element. The magnetic clutch is for rotationally coupling the driver to the torque admission element.
