A controllable one-way clutch assembly having an actuator module equipped with a solenoid actuator, an active strut moveable in response to energization of the solenoid actuator from a released position to a locked position, a strut spring biasing the active strut toward its released position, and an indirect strut actuation arrangement between the solenoid actuator and the active strut. The indirect strut actuation arrangement includes an intermediate actuation component having a first lug establishing a coupling interface with a translatable plunger of the solenoid actuator and a second lug establishing an engagement interface with the active strut.

Selectable one-way clutch with solenoid actuator and pivoting actuation member controlling active strut deployment

A dual-acting selectable one-way coupling (SOWC) device configured to include a clutch module and an electromagnetic actuator module. The clutch module includes an outer race and an inner race assembly rotatable relative to the outer race. The inner race assembly including a rotatably driven first inner race member, a second inner race member, and compliant connector members drivingly interconnecting the first and second race members. The electromagnetic actuator module includes an electromagnetic actuator operable to releasably engage the second inner race member. An auxiliary locking assembly is operable to independently releasably engage the second inner race member.

Dual-acting electric one-way clutch assembly

A method for forming a component utilizing ultra-high strength steel and components formed by the method. The method includes the step of providing a flat blank of ultra-high strength 22MnB5 steel. The next step of the method is cold forming the flat blank into an unfinished shape of a component while the blank is in an unhardened state. Then, heating the unfinished shape of the component and generating a spline form thereon. The method proceeds by forming a finished shape of the component using a quenching die resulting in a fine-grained martensitic component material structure and enabling net shape processing to establish final geometric dimensions of the component.

A starting system for a vehicle including an internal combustion engine having a crankshaft includes a pinion gear driven by a starter motor. A drive plate includes a set of teeth in constant meshed engagement with the pinion gear. A one-way clutch assembly is adapted to drivingly interconnect the drive plate and the crankshaft. The clutch assembly includes an inner race adapted to be fixed for rotation with the crankshaft, an outer race fixed for rotation with the drive plate, and a plurality of rollers positioned radially therebetween. One of the inner and outer races includes circumferentially spaced apart cam surfaces. The clutch assembly also includes a cage for positioning the rollers in a circumferentially spaced apart alignment with the cam surfaces and a roller bearing assembly positioned axially offset from the one-way clutch rollers to rotatably support the outer race on the inner race.

A method is disclosed for making a differential housing having a ring gear integrally formed therein. The method includes the steps of forging a conical frustum from a steel rod; deforming the frustum between upper and lower die halves of a tool to produce a differential housing having an annular rim; and forging a plurality of teeth in the annular rim defining the rim gear.
