Abstract:

A transmission system includes a transmission housing and a countershaft having no less than two gears, with the gears defining a plurality of gear ratios. The transmission system also includes a module housing, a first output shaft rotatably coupled to the countershaft, and a second output shaft rotatably coupled to the countershaft. The transmission system further includes a first clutch configured to selectively rotatably couple the first output shaft to the countershaft. The transmission system also includes a second clutch configured to selectively rotatably couple the second output shaft to the countershaft. The transmission system further includes an electric machine configured to deliver rotational power to at least one of the first and second output shafts to deliver rotational power to the countershaft. The countershaft is rotatably coupled to either of the first and second output shafts for all of the gear ratios.

Appl. No.:

15/443108

Inventors:

- Auburn Hills MI, US
Brett PEGLOWSKI - Oakland MI, US
Christopher A. SPANGLER - Rochester Hills MI, US

International Classification:

F16D 23/12
F16D 41/12
F16D 25/08

Abstract:

An actuation device having a piston is used to actuate a mechanical or friction clutch by means of differential pressure. Two sides of a piston are pressurized, and the relative pressure between the two sides is decreased or increased to move the piston in either direction. The position of the piston may be determined using position feedback, or with springs of known spring rates, two piston areas, and knowing the pressures of the two areas. The actuation device may be used with a selectable clutch to actuate an actuation cam, and may also have application with other clutches requiring the ability to achieve multiple positions and clutch modes.

Abstract:

The selectable clutch may include a first actuator and a second actuator. Moreover, the selectable clutch may further include a first cam operatively associated with the first actuator and a second cam operatively associated with the second actuator. Furthermore, a first armature may be actuated by the first actuator and a second armature may be actuated by the second actuator such that the selectable clutch is configured to allow multiple modes of operation provided by a movement of the first and second cams according to different first and second armature positions.
