A drive module assembly for use in a vehicle includes a housing defining a housing interior and an electric machine. The electric machine includes a rotor and a stator. The drive module assembly includes a first input shaft, a second input shaft, a first output shaft, a second output shaft, and a differential disposed downstream of at least the rotor. The drive module assembly also includes a gearset, a clutch, and a park lock. The gearset, the clutch, and the park lock are disposed downstream of the differential such that the gearset and the clutch are configured receive rotational torque from the differential through the first and second output shafts.

Drive module assembly

A solenoid assembly includes a solenoid adapted to be coupled to a solenoid connecting member, with the solenoid connecting member extending from a support member. The solenoid assembly also includes a retaining bracket having a body portion and a securing portion extending from the body portion. The body portion is adapted to be removably coupled to the solenoid connecting member, and the securing portion is removably coupled to the solenoid. The retaining bracket is moveable between an unsecured position, and a secured position. The securing portion of the retaining bracket provides a spring force to the solenoid when the retaining bracket is in the secured position such that the solenoid is biased toward the solenoid connecting member to secure the solenoid between the solenoid connecting member and the securing portion of the retaining bracket.

Hydraulic control module and solenoid assembly included therein

A forward/reverse planetary gearset () may be adapted to employ multi-mode clutch modules () in lieu of using only traditional friction clutches (). Such arrangement may reduce parasitic drag as well as achieve reductions in physical size of the gearset housing (). Use of multi-mode clutch modules () may offer either of or both forward and reverse controls of the planetary gearset (). Thus, in at least one arrangement a multi-mode clutch () may provide forward clutch control while a friction clutch () provides reverse clutch control. In another arrangement the friction clutch () may provide the forward clutch control, while the multi-mode clutch () provides the reverse clutch control for the gearset (). Finally, both forward and reverse controls of the gearset () may be provided via multi-mode clutches (), thus entirely avoiding use of any friction clutches () for forward or reverse control functions of the planetary gearset ().

Multi-mode clutches for forward/reverse planetary gearset

In a parallel hybrid vehicle having and internal combustion engine and an electric motor operatively connected to a transmission shaft, a multimode mechanical clutch selectively couples an output shaft of the internal combustion engine to the transmission shaft. The multimode clutch has a two-way unlocked mode where the output shaft and transmission shaft can rotate independently in either direction, and a one-way locked, one-way unlocked mode where the shafts are locked to rotate together in one direction and unlocked for independent rotation in the opposite direction. The clutch may also have a two-way locked mode where the shafts rotate together in both directions. Pawls may be provided to engage and disengage as needed to execute the modes of the multimode clutch actuator.
