Patent number: 9964184Abstract: A variable state planetary shifting transmission can include an input shaft, an output shaft; and a planetary system having a sun gear associated with the input shaft, a planetary carrier, and a ring gear associated with a ring housing. The transmission can include an overrunning clutch operably coupled to the planetary carrier. The transmission can include a clutch assembly coupled to the planetary carrier. The transmission is capable of changing the speed ratio between the input shaft and the output shaft by selective engagement of the clutch assembly against the ring gear which can cause either the freeing or locking of the planetary carrier by the overrunning clutch.Type: GrantFiled: April 10, 2015Date of Patent: May 8, 2018Assignee: Bell Helicopter Textron Inc.Inventors: Brian Stanley Modrzejewski, Russell Mueller, Doug Mueller, Ron Woods, Tim Cecil

Patent number: 9643719Abstract: According to one embodiment, a flight control device includes a grip, a stick associated with the grip, and a gimbal. The stick defines a first axis. The gimbal includes a first platform, a second platform, a first electro- rheological elastomeric bearing, and a second electro-rheological elastomeric bearing. The first platform is coupled to the stick and configured to rotate on a second axis that is perpendicular to the first axis. The second platform is in mechanical communication with the first platform and configured to rotate on a third axis that is perpendicular to the second axis. The first electro-rheological elastomeric bearing defines the second axis, and the second electro-rheological elastomeric bearing defines the third axis. The first and second electro-rheological elastomeric bearing being configured to each have a variable stiffness.Type: GrantFiled: June 24, 2015Date of Patent: May 9, 2017Assignee: Bell Helicopter Textron Inc.Inventor: Brian Stanley Modrzejewski

Patent number: 6913446Abstract: An auxiliary solenoid controlled variable displacement power steering pump, hydraulic systems incorporating same, and method for improving the efficiency of variable displacement power steering pumps. In one embodiment, a rotor is arranged within a pump body, and a cam fitted on an outer periphery of the rotor and movably arranged within the pump body to form a variable volume pump chamber. The cam is biased towards a position within the pump body to create maximum displacement. A mechanism is provided for forcing the cam into a position of fixed minimum or reduced displacement under certain conditions, such as low engine speed and power steering demand. In a preferred embodiment, the mechanism comprises a solenoid driven connecting rod that is operatively connected to the cam. Activation of the solenoid forces the cam to a position of fixed minimum or reduced displacement.Type: GrantFiled: June 11, 2002Date of Patent: July 5, 2005Assignee: Visteon Global Technologies, Inc.Inventors: Steven Thomas Nissen, Brian Stanley Modrzejewski, Shawn Patrick Cap'Ser

Patent number: 6817438Abstract: A variable displacement pump is provided. A pump body has an outer ring defining an inner cavity, where the inner cavity further defines a pump suction path and a pump discharge path in fluid communication with the inner cavity. A cam ring is pivotably supported in the inner cavity by a pivot pin formed on a portion of an inner diameter of the adapter ring. An actuated cam is formed on the cam ring. An actuator is linked through the actuated cam to the cam ring for moving the cam ring in a pivotable motion. A control module is linked to the actuator.Type: GrantFiled: December 28, 2001Date of Patent: November 16, 2004Assignee: Visteon Global Technologies, Inc.Inventors: Brian Stanley Modrzejewski, Shawn Patrick Capser, Steven Thomas Nissen

Patent number: 6666670Abstract: A power steering pump for an automotive vehicle includes a housing having an inner wall with an axial groove. A cam plate that defines a cam chamber is received in the housing and includes a rib received in the groove. The groove and rib are disposed near the outlet port of the cam chamber and are dimensioned such that, during operation, distortion of the cam plate directs the rib into locking engagement with the groove while maintaining clearance between the housing and remainder of the cam plate to reduce propagation of vibration and noise.Type: GrantFiled: May 22, 2003Date of Patent: December 23, 2003Assignee: Visteon Global Technologies, Inc.Inventors: David Ray Hartman, Brian Stanley Modrzejewski, Brandon William Bailey, Michael Dean Strickler, Rakesh Nahta, Michelle Koch
