Patent number: 8166650Abstract: A method of manufacturing a printed circuit board (PCB) includes of disposing thermal transfer vias and electrical vias through the PCB. The method further includes filling holes of the vias with a solder mask. The thermal transfer vias are filled to about 70% of capacity while the electrical vias are completely filled. Once filled, surfaces of the PCB are coated with an organic solderability preservative.Type: GrantFiled: May 30, 2008Date of Patent: May 1, 2012Assignee: Steering Solutions IP Holding CompanyInventor: Wayne Bernard Thomas

Patent number: 8162767Abstract: A constant velocity joint assembly includes an outer joint member and an inner joint member. A first shaft is coupled to the inner joint member for articulated movement with the inner joint member relative to the outer joint member. A boot is coupled to the first shaft and the outer joint member to seal the constant velocity joint assembly. An insert is secured to and supported within the boot adjacent to and in abutting engagement with an axial end of the outer joint member. The insert limits movement of the first shaft to within a pre-determined range of articulation to prevent disengagement and/or disassembly of the inner joint member relative to the outer joint member.Type: GrantFiled: April 20, 2009Date of Patent: April 24, 2012Assignee: Steering Solutions IP Holding CompanyInventor: Michael J. Holzhei

Patent number: 8155838Abstract: A method for generating a return torque signal in an electric servo steering system of a vehicle, including the steps of: determining a current steering wheel position; determining a current vehicle speed; generating a return torque signal as a function of the steering wheel position and the vehicle speed; determining a current directional relationship between a torque exerted on the steering wheel and a speed of steering wheel rotation; determining a scaling factor dependent on the directional relationship; and multiplying the return torque signal by the scaling factor in order to obtain a modified return torque signal. Also, a servo steering system which is designed to carry out such a method.Type: GrantFiled: January 16, 2009Date of Patent: April 10, 2012Assignee: Steering Solutions IP Holding Company, a Delaware corporationInventor: Bertram Moeller

Patent number: 8127639Abstract: A telescopically collapsible vehicular steering column assembly includes inner and outer shaft tubes which are joined in a sliding fit by a bushing. The bushing includes a pair of spaced journal bearings formed of steel-backed PTFE held in a plastic carrier body. The bushing is located in a receiving chamber in the outer shaft tube. A clearance compensator reacts against the receiving chamber to exert a radial compressive force through the carrier body and the journal bearings to improve the sliding fit with the inner shaft tube and remove lash. The clearance compensator can take any form, such as a hollow annular rib, a skirt with a flexible free end, or an array of nubs carried in thinned sections of the carrier body. The clearance compensator in all of these variations operates within a clearance space and has dimensional attributes which can be changed during the design and manufacturing phases of the bushing to optimize a characteristic of the steering column assembly.Type: GrantFiled: August 16, 2005Date of Patent: March 6, 2012Assignee: Steering Solutions IP Holding Company, a Delaware corporationInventors: Marvin V. Manwaring, Richard K. Riefe, Ray G. Armstrong, Ravi Ravindra

Patent number: 8123251Abstract: An adjustable steering column assembly for a vehicle preferably has a bracket for rigid attachment to the vehicle with a first slot defining a longitudinal adjustment path of the assembly. A steering shaft is journaled to a jacket of the assembly for rotation about an axis. A shuttle attaches rigidly to the jacket and adjustably to the bracket for telescoping and tilt adjustment of the assembly. The shuttle has a second slot that defines a collapse path with said second slot preferably having a first portion restraining said steering shaft in a normal state and a second portion that allows said steering shaft to move through said collapse path when in a collapsed state. A pin extends through said first and second slots for coupling said shuttle to said bracket.Type: GrantFiled: December 17, 2009Date of Patent: February 28, 2012Assignee: Steering Solutions IP Holding CompanyInventors: Leland N. Olgren, Michael S. Gregus, Donald A. Niedzielski, Germaine Niedzielski, legal representative, Roger A. Bourbina, Jeff A. Gregg
