Patent number: 9482297Abstract: A controllable or selectable coupling assembly includes a plurality of forward locking elements, at least one reverse locking element and first and second coupling members supported for relative rotation about a common rotational axis. The coupling members include a first, second and third coupling faces. The first coupling face has a set of forward pockets angularly spaced about the axis. The second coupling face has a set of reverse locking formations adapted for abutting engagement with the at least one reverse locking element. The third coupling face opposes the first coupling face and has a set of forward locking formations. Either forward backlash is a non-zero integer multiple of reverse backlash or the reverse backlash is a non-zero integer multiple of the forward backlash to prevent the coupling assembly from inadvertently binding in both directions (i.e. a “lock-lock” condition) about the axis.Type: GrantFiled: April 1, 2015Date of Patent: November 1, 2016Assignee: Means Industries, Inc.Inventors: Douglas E.

Patent number: 9188170Abstract: A coupling and control assembly includes a coupling subassembly and a control subassembly integrated with the coupling subassembly. The control subassembly has a reciprocating member and actuators operatively connected to the reciprocating movement for controlled reciprocating movement therewith to move or pivot respective struts received within pockets of a coupling member of the coupling subassembly. The reciprocating member converts a pressure of a working fluid at its working face to move linearly together with the actuators from its first position which corresponds to a first operating mode of the coupling subassembly to its second position which corresponds to a second operating mode of the coupling subassembly.Type: GrantFiled: April 16, 2013Date of Patent: November 17, 2015Assignee: MEANS INDUSTRIES, INC.Inventors: Jeffrey J.

Patent number: 9188174Abstract: A controllable or selectable coupling assembly having an overrun mode and a retained control element is provided. The assembly includes first and second coupling members having first and second coupling faces, respectively, in close-spaced opposition with one another. A locking member is disposed between the coupling faces of the coupling members. The locking member is movable between first and second positions. A control element is mounted for controlled movement between the coupling faces and is operable to control position of the locking member. The control element has at least one opening which extends completely therethrough to allow the locking member to extend therethrough. A retainer mechanism is operative to allow limited movement of the control element towards the first coupling face and prevent the control element from contacting the first coupling member in the overrun mode thereby reducing spin losses when the assembly is disengaged.Type: GrantFiled: January 8, 2014Date of Patent: November 17, 2015Assignee: MEANS INDUSTRIES, INC.Inventors: Carl T. Beiser, George J. Coppens, Brice A. Pawley

Patent number: 9188172Abstract: A compact overrunning coupling and control assembly having reduced part count and manufacturing complexity is provided. An actuator arm moves a control element from a first position which corresponds to a first mode of the assembly to a second position which corresponds to a second mode of the assembly. An actuator piston is disposed within the bore of a housing and has an outer surface in sliding contact with the inner surface of the housing and a groove formed in the outer surface of the piston to receive and retain a free end portion of the actuator arm therein. A control pressure signal within the housing causes the piston to slide within the bore against a biasing force to move the actuator arm.Type: GrantFiled: January 8, 2014Date of Patent: November 17, 2015Assignee: MEANS INDUSTRIES, INC.Inventors: Robert D. Fetting, Brice A. Pawley

Patent number: 9121454Abstract: A locking member for controllably transmitting torque between first and second coupling members of a coupling assembly is provided. The locking member includes projecting inner and outer pivots which extend laterally from a main body portion for enabling pivotal motion of the locking member about a pivot axis which intersects the pivots. The pivots are sized, shaped and located with respect to the main body portion to allow frictional engagement of an end surface of the outer pivot with an outer wall of a pocket to occur near the pivot axis during rotation of the first coupling member and the locking member above a predetermined RPM thereby reducing overall moment on the locking member about the pivot axis that has to be overcome to move the locking member between the engaged and disengaged positions.Type: GrantFiled: September 25, 2013Date of Patent: September 1, 2015Assignee: MEANS INDUSTRIES, INC.Inventor: Brice A. Pawley

Patent number: 7344010Abstract: An overrunning coupling assembly and a method of controlling the engagement of planar first and second members are provided wherein the assembly includes clustered pawls and their respective pawl-holding portions. The planar first and second members have inside surfaces extending generally normal to a first axis. The pawls include a forward set of free-floating pawls and a reverse set of free-floating, clustered pawls. The forward and reverse sets of pawls are movable between a notch-engaging, engaged position and a disengaged position. Because of the clustering, a control element, disposed between the first and second surfaces, need not be fully circular and is controllably rotatable about the first axis between first and second angular positions relative to the first member.Type: GrantFiled: September 14, 2005Date of Patent: March 18, 2008Assignee: Means Industries, Inc.Inventors: Robert D.

Patent number: 7275628Abstract: An overrunning coupling assembly having improved shift feel and/or noise reduction is provided. The assembly includes planar first and second members rotatable about a first axis. In a locked position, torque transfer is permitted between the first and second members in a first direction about the first axis. In a disengaged position, the first and second members are permitted to free-wheel relative to each other in a second direction opposite the first direction. A compliant retaining device retains the first and second members together and absorbs axial impact loads. The retaining device is less compliant in the locked position than in the disengaged position to decrease axial force at time of axial impact and improve shift feel and/or noise reduction. In a first embodiment, the retaining device includes a wave spring. In a second embodiment, the retaining device includes a stepped weir plate.Type: GrantFiled: June 9, 2005Date of Patent: October 2, 2007Assignee: Means Industries Inc.Inventors: Brice A.
