Patent number: 8708357Abstract: A pinion shaft of a steering system has a plurality of pinion teeth. A rack shaft has a stroke region in which a plurality of rack teeth that mesh with the pinion teeth is formed. The stroke region includes a center region that includes a center position of the stroke region, end regions, each of which includes an end position of the stroke region, and intermediate regions, each of which is located between the center region and one of the end regions. A pressure angle of each rack tooth included in each of the intermediate regions is smaller than a pressure angle of each rack tooth included in each of the center region and the end regions.Type: GrantFiled: February 27, 2013Date of Patent: April 29, 2014Assignee: JTEKT CorporationInventor: Hidetoshi Sumihara

Patent number: 8473160Abstract: A steering operation force detection device for a steering wheel including a steering wheel rim having a right-side rim section and a left-side rim section. The device includes load cells that detect six component forces of the steering operation force acting on the right-side rim section and the left-side rim section consisting of forces in three axial directions and moments about three axes. The device includes a steering angle detection sensor that detects a steering angle of the steering wheel, and an inertial force component correcting unit that derives an inertial force component acting on the right-side rim section and the left-side rim section due to rotation of the steering wheel, based on an amount of displacement of the steering angle detected by the steering angle detection sensor, and that corrects the component force detected by the load cells to eliminate an effect of the derived inertial force component.Type: GrantFiled: June 30, 2011Date of Patent: June 25, 2013Assignee: The Yokohama Rubber Co., Ltd.Inventor: Akira Kuramori

Patent number: 8096208Abstract: A positioning apparatus for a shift control device for a bicycle transmission comprises a movable member having a positioning element, a positioning member having a positioning element structured to engage the positioning element of the movable member, and a biasing member that biases the positioning member towards an engaged position wherein the positioning element of the positioning member engages the positioning element of the movable member. The positioning member moves toward and away from a plane of movement of the movable member. A releasing member is disposed between the movable member and the positioning member, wherein the releasing member moves between an initial position and an operating position. The releasing member allows the positioning member to be in the engaged position when the releasing member is in the initial position, and the positioning member moves to the disengaged position when the releasing member moves to the operating position.Type: GrantFiled: October 1, 2007Date of Patent: January 17, 2012Assignee: Shimano (Singapore) Pte. Ltd.Inventor: Yau Yong Sean
