  • Patent number: 10690198
    Abstract: An electric motor includes a housing and a stator mounted to the housing. A rotor is rotatably supported relative to the stator and a drive shaft is connected to the rotor by a torque limiting clutch disposed within the housing. The electric motor with a torque limiting clutch eliminates high torque episodes due to slippery driving conditions. Also, a torque limiting clutch that features a ball-ramp device with two ramp angles performs the function of a two stage torsional vibration damper. An electric motor can have a specific torque signature that can excite certain vibration modes inside the transmission that can create noise, vibration and harshness (NVH) and durability concerns.

  • Patent number: 10688595
    Abstract: A method of laser welding a workpiece stack-up (10) that includes at least two overlapping steel workpieces (12, 14) comprises directing a laser beam (40) at a top surface (26) of the workpiece stack-up to form a keyhole (56) surrounded by a molten steel weld pool (58). The laser beam is conveyed along a predefined weld pattern that includes one or more nonlinear inner weld paths (66) and an enclosed outer peripheral weld path (68) surrounding the one or more nonlinear inner weld paths. During conveyance of the laser beam along the one or more nonlinear inner weld paths, the keyhole fully penetrates through the workpiece stack-up from the top surface of the stack-up to the bottom surface (28) of the stack-up. The method produces weld joints between the steel workpieces that do not have an intentionally imposed gap formed between their faying surfaces.
