  • Publication number: 20240149714
    Abstract: A method includes receiving an indication of a charging current received at an on-board charging circuit of a vehicle from a source having a charging voltage. The on-board charging circuit includes a multi-phase traction motor, an inverter electrically coupled to the multi-phase traction motor and including an upper set of switching elements and a lower set of switching elements, and an energy storage device (ESD) electrically coupled to the inverter and having a storage voltage. The method includes determining whether the charging voltage is greater than or equal to the storage voltage. When the charging voltage is greater than or equal to the storage voltage, the method includes instructing at least one switching element in the upper set to operate in an on state and all of the switching elements in the lower set in an off state to cause fast charging of the ESD using the charging current.

  • Patent number: 11848546
    Abstract: A flexible wire support structure extends between an axle and an inverter for an electric vehicle. The inverter is fixed relative to the vehicle body and the axle is moveable relative to the inverter during vehicle use. A wire extends between the inverter and the axle through a channel defined by the wire support structure. The wire support structure is attached at opposite ends to a first and second support structure, each of which allow pivoting of the flexible wire support structure in response to movement of the axle relative to the inverter. The wire support structure has a limited bend radius in response to movement of the axle, and blocks the wire extending within the support structure from being bent to a tight radius, thereby protecting the wire.

  • Patent number: 11168743
    Abstract: A clutch assembly incorporated into a power transfer assembly (72) of a motor vehicle is presented. The clutch assembly includes a power-operated clutch actuator (306) for moving a clutch sleeve (354) axially between released and engaged positions between two rotatory members. In the released position, relative rotation between two rotary members is prevented. Whereas in the engaged position, relative rotation is permitted. The power-operated clutch actuator (306) further includes an electromagnetic solenoid with an output member having an extended condition and a retracted condition urging the clutch sleeve (354) between positions. A shift isolation linkage mechanism (304) interconnects the output member of the solenoid to the clutch sleeve (354) and permits movement of the output member to its retracted position while a blocked tooth condition inhibits movement of the clutch sleeve (354) to its engaged position.

  • Patent number: 9028332
    Abstract: A cap acting as a grease retention feature and venting system allows crash optimization of a propeller shaft with a plunging constant velocity joint. The cap is located between a constant velocity joint and a tube of the propeller shaft system. The cap includes: a rim sealed against the inner diameter of the constant velocity joint, an interior vent chamber, a vent hole facing the interior components of the constant velocity joint and leading to the vent chamber, and an annular radial groove along the entire circumference connected to the vent chamber. The outer race has a hole perpendicular to the joint axis to complete venting to the atmosphere. In the event of a vehicle crash, the constant velocity internal joint components contact the device, causing the device to dislodge from its fixed position, contact the friction weld curls and fracture at a determined load.
