Embodiment Construction

[0016] Referring now to FIGS. 1 a - 1 c , several non-limiting examples of selectable clutch modules constructed in accordance with the present invention are generally referred to by the element numeral 10 . The optional clutch module 10 may be used in a variety of machines such as, but not limited to, automobiles, trucks, vans, farm equipment, and construction equipment. The optional clutch module 10 may include an actuator 12 . The actuator 12 may include an armature 14 . Armature 14 may be coupled to cam 16 via pin 18 . Actuator 12 may be a solenoid device, magnetic device, servo motor, hydraulic device, or other type of actuator. A biasing member 20 may be disposed about the armature 14 between the cam 16 and the actuator 12 . Actuator 12 is actuatable to move armature 14 and cam 16 .

[0017] The optional clutch module 10 may include a first component 22 . In some embodiments, the first member 22 may be configured as a non-rotating component of the selectable clutch ...

Abstract

The selectable clutch module may include a first member and a second member positioned adjacent to the first member. The selectable clutch module may further include a plurality of notches formed on the second member and an actuator operably coupled to an armature. Furthermore, the selectable clutch module may include a selectable locking mechanism including a first pawl and a second pawl, wherein the first and second pawls are configured to interact with the plurality of notches such that the selectable locking mechanism is selectively controlled between a plurality of locking modes. The selectable clutch module may further include a cam operatively associated with the armature and the cam may include a cam profile configured to engage with the first and second pawls. Moreover, the actuator may position the cam profile to selectably actuate the selectable locking mechanism into one of the plurality of locking modes.

Description

technical field [0001] The present invention relates generally to clutches, and more particularly to selectable clutch modules. Background technique [0002] Some machines such as automobiles, trucks, vans, farm equipment, construction equipment, and other such vehicles may be equipped with selectable clutch modules. In some alternative clutch module designs, it may be desirable for the engaged pawl to release in response to torque. The cam is typically actuatable to engage the heel of the engaged pawl to release it. However, the geometry of the cam typically limits the force or requires a long stroke of the pawl. Contents of the invention [0003] According to one aspect of the present invention, a selectable clutch module is provided. The selectable clutch module may include a first component and a second component positioned adjacent to the first component and configured to rotate relative to the first component. The selectable clutch module may further include a pl...
