Title: Shigeo Aiba: Innovator in Automotive Steering Technology
Introduction
Shigeo Aiba is a notable inventor based in Aichi, Japan, recognized for his contributions to automotive steering technology. With a total of 3 patents, Aiba has made significant advancements in the design and functionality of rack and pinion steering devices.
Latest Patents
Aiba's latest patents include innovative designs aimed at improving the performance of steering systems. One of his notable inventions is a rack guide of synthetic resin for a rack and pinion type steering device. This synthetic resin rack guide is designed to be housed in a gear box of a vehicle's steering device. It features a generally semi-cylindrical head that includes a semi-cylindrical concave surface, which allows for smooth contact with the back surface of a rack bar. The design incorporates an outer cylinder and an inner cylinder, separated by a circumferentially extending space. This unique structure allows the outer cylinder to shrink radially inward when inserted into a rack housing, preventing locking and ensuring smooth sliding even with temperature fluctuations.
Another significant patent is the rack guide in a rack-and-pinion type steering gear. This invention includes a projection on the outer peripheral surface at an end portion that contacts the rack bar. The projection is designed to maintain a diameter that is equal to or slightly larger than the inner diameter of the guide hole, effectively preventing abnormal noise between the rack teeth and the pinion.
