A vehicle includes at least one drive wheel, a powerplant, a clutch, and a controller. The powerplant is configured to generate and deliver power to the at least one drive wheel. The clutch is disposed between the at least one drive wheel and the powerplant. The controller is programmed to, in response to detecting the at least one drive wheel disengaging the ground during a vehicle jump, open the clutch to disconnect the at least one drive wheel from the powerplant.

This disclosure details cooling systems for cooling electric components, such as electric machines, within electrified vehicles. Exemplary cooling systems may include a spray bar positioned relative to a rear face of a stator of the electric machine. In some embodiments, the spray bar may be positioned axially between the rear face of the stator and a torque converter housing. One or more nozzles of the spray bar are configured to direct a coolant between adjacent back irons of the stator, onto end windings of the stator, or both. Actively cooling the stator allows the electric machine to operate at higher torques and speeds, thereby increasing performance.

Methods and systems for an electric motor-generator in a vehicle are provided. In one example, an electric motor-generator is provided that includes an engine interface configured to rotationally couple to a first engine, a transmission interface configured to rotationally couple to a first transmission of the first engine, and a rotor with a plurality of magnets at least partially surrounding a stator including a plurality of coils. The rotor is rotationally coupled to the engine interface and the transmission interface.

Methods and systems are provided for a cooling jacket for a stator. In one example, the cooling jacket is cast as a single piece with windings of the stator pressed into a surface of the cooling jacket.

A vehicle includes a planetary gear set, a gearbox, an electric machine, and an engine. The planetary gear set has a sun gear, a carrier, and a ring gear. The gearbox is configured to transmit power from the ring gear to vehicle wheels. The electric machine is fixedly coupled to the sun gear. The engine is selectively coupled to the ring gear via a first selectable one-way clutch and selectively coupled to the carrier via a second selectable one-way clutch.

Hybrid vehicle

A vehicle includes a continuously-variable transmission (CVT) that is supplied with power from an input. The CVT also includes a pair of pulleys, at least one of which having a variator that is configured to translate linearly along an axis of the input. A mechanical lock is configured to selectively lock the input with the variator such that the input and the variator rotate in unison. This allows the hydraulic pressure supplied to the CVT to reduce while the variator and the input remain locked.

Continuous variable transmission with mechanical lock

A vehicle includes an engine, motor, transmission, and electronically controlled one-way clutch. The engine includes an output. The motor includes a rotor and a stator. The transmission includes an input that is rotatably coupled to the rotor. The transmission is configured to receive power from the engine and the motor. The electronically controlled one-way clutch has an inner race that is secured to the output of the engine and an outer race that is secured to the rotor. The electronically controlled one-way clutch is configured to rotatably couple the output to the rotor.

Hybrid vehicle and powertrain

A continuously variable transmission includes a first shaft driveably connected to a power-plant and having a first pair of sheave disks, and a second shaft having a second pair of sheave disks. A tension member is connected to the first and second pairs of disks such that power is transmittable between the first and second shafts. A third shaft is selectively driveably connected to the second shaft via a clutch. The clutch includes an inner race fixed to one of the second and third shafts, and an outer race fixed to a gear and having an inner surface circumscribing the inner race. At least one pawl is biased to couple the races in a fixed relationship for common rotation. The clutch further includes an electric coil and an armature configured to engage the pawl to decouple the races in response to current being supplied to the electric coil.

Clutch for continuously variable transmission

A vehicle including a continuously variable transmission including a gear selectively locked to an output shaft via a clutch actuated by an electric coil. The vehicle also includes a controller configured to, in response to wheel hop being detected, energize the coil to disengage the clutch allowing the gear and the output shaft to rotate independently of each other.
