Patent number: 9296412Abstract: A steering yolk bearing assembly includes a body. The body can include a first end having a flat surface and a second end opposite the first end. The second end can have a concave surface having a radius of curvature, RCS, a first lateral side and a second lateral side opposite the first lateral side. A first bearing pad can extend from the first lateral side of the concave surface and a second bearing pad can extend from the second lateral side of the concave surface opposite the first bearing pad. Each bearing pad can include a shaft contact surface having a radius of curvature, RSCS, and RSCS?2×RCS.Type: GrantFiled: September 27, 2013Date of Patent: March 29, 2016Assignee: Saint-Gobain Performance Plastics CorporationInventor: Nicholas Witting

Patent number: 9278707Abstract: A steering yoke is disclosed and includes a hollow cylindrical body that can be formed from a laminated sheet of metal and polymer. The hollow cylindrical body includes a substantially uniform wall thickness. Further, the hollow cylindrical body can include a first half, a second half, a seam extending at least partially along the body between the first half and the second half, an upper end having a surface, and a lower open end. The steering yoke can also include a bearing surface coupled to the surface of the upper end of the hollow cylindrical body and a spring perch disposed in the lower end of the hollow cylindrical body. The spring perch can include a spring pocket configured to support and retain a spring for supplying a biasing force to the yoke.Type: GrantFiled: December 3, 2013Date of Patent: March 8, 2016Assignee: Saint-Gobain Performance Plastics CorporationInventors: Nicholas Witting, Joseph Liquore, Timothy J.

Patent number: 8375818Abstract: A yoke for use in a rack and pinion steering assembly is described. The yoke may include a bearing surface that provides a low coefficient of friction, allowing for a greater biasing force against the rack shaft. The materials and design of the yoke can provide for a quieter system with reduced vibration.Type: GrantFiled: June 19, 2009Date of Patent: February 19, 2013Assignee: Saint-Gobain Performance Plastics CorporationInventors: Nicholas Witting, Joseph Liquore, Timothy J.
