Latest Patents
One of Kitami's latest patents is an electric power steering system. This invention features a curved leaf spring that acts as a first urging member, surrounding an outer wheel of a second bearing. It urges, through the second bearing, a second end of a worm shaft in a direction that shortens the distance between the center of the worm shaft and the center of a worm wheel. Additionally, a second urging member includes an annular support member received by an end surface of the outer wheel, along with a plurality of elastic pins that extend parallel to the axial direction of the support member. These elastic pins have fixed ends attached to the support member and free ends that make elastic contact with an end wall of a housing.
Another significant patent is for a power steering apparatus. This invention addresses the scenario when a steering wheel is quickly turned during parking. Before a first stopper mechanism between an input shaft and an output shaft is activated, an elastic member attached to the movement end of a rack shaft contacts a rack stopper of a rack housing. This design absorbs the impact during steering at parking, thereby slowing down the strike speed when the contact portions of the first stopper mechanism meet. As a result, the uncomfortable noise from the strike sound is minimized for the driver.
