Abstract: An electromechanically assisted steering system is proposed, having a worm drive which comprises a worm shaft and a worm gear, an electric motor which has a drive shaft, and a spring element. At an end assigned to the electric motor, the worm shaft has a first bearing portion which is connected to the drive shaft in a torque-transmitting manner. The worm shaft has a second bearing portion which is arranged at an end of the worm shaft remote from the first bearing portion. The spring element is connected to the first bearing portion or to the second bearing portion so as to transmit axial force in the axial direction, such that the spring element axially pretensions the worm shaft relative to the worm gear. A tolerance compensation of the worm drive in the axial direction of the worm shaft is carried out exclusively via the spring element.

Abstract: A snag point cover for an industrial manufacturing robot, the snag point cover including: a body adapted to be disposed about a protrusion extending from an external surface of an industrial manufacturing robot, wherein the body is adapted to form an external transition surface between the protrusion and the external surface of the industrial manufacturing robot thereby preventing a dresspack from becoming snagged on the protrusion when the industrial manufacturing robot is articulated. The snag point cover body is adapted to surround and cover one or more protrusions. The snag point cover body may be elongated or arcuate in shape and defines an internal cavity that conforms to the one or more protrusions. This allows external structures such as wiring harnesses and conduits to slide over these protrusions without becoming snagged or pinched during complex motion.

Abstract: A method for controlling an electric drive unit (EDU) having a motor-driven torque converter includes receiving a request signal indicative of a requested output torque of the EDU, and operating the motor at a target motor speed using the requested output torque. The target motor speed minimizes system losses while achieving the requested output torque. When the requested output torque remains below a calibrated threshold and a turbine speed is less than a corner speed of the motor, a torque converter clutch (TCC) transitions to or remains in a locked state. The controller commands the TCC to transition to an unlocked state to reach the target motor speed, thereby selectively enabling torque multiplication. A powertrain system includes a driven load and the EDU. A computer readable storage medium may include executable instructions for performing the method.

Abstract: A transmission is presented, including a spool having a bore. An outer member disposed on the spool, and a cord is configured to at least partially wrap around the outer member. The outer member is configured to constrict and unconstrict to a force applied to the outer member. In this way, rotation of the spool causes a tension force to be applied to the cord, and a greater tension force in the cord will cause the outer member to constrict more than a lower tension force in the cord.

Abstract: The disclosure specifies a gear assembly for an electric-motor assisted steering system, comprising an electric motor, a worm shaft which can be driven by the electric motor and which meshes with a worm wheel. The worm shaft has a recess on an end face which faces the electric motor, in which recess there is arranged an elastic element which applies an axial force to the worm shaft in the direction away from the electric motor. In the axial direction, the elastic element is supported by one end on an adjustment element, which is formed in such a way that it permits expansion of the elastic element in the axial direction when the axial force on the worm shaft exceeds a defined threshold value, and limits expansion of the elastic element when the axial force on the worm shaft lies below the defined threshold value.

Abstract: In a shift device, a shift position of a knob is altered as a result of a knob being rotated. Furthermore, a Hall IC on a wiring substrate detects a rotation position of a magnet in the knob, thereby enabling the shift position of the knob to be detected. Here, the Hall IC is placed on an outer side in a rotation radial direction of the magnet. Because of this, it is possible to enlarge the change in the relative position between the magnet and the Hall IC that is generated by the rotation of the magnet, thereby enabling the detection accuracy when detecting the shift position of the knob to be improved.

The system includes a mode input device configured to select in advance one of the first manual mode and the second manual mode to be set, the mode input device setting to the automatic transmission mode by the selected mode being changed from the first manual mode to the second manual mode, or vice versa.
