Abstract

PURPOSE:To improve the steering efficiency by supporting a rack bar with a rolling contact roller at a time of steering where the rack bar is usually supported by a friction contact york. CONSTITUTION:When a rack bar 13 is subjected to a low load, the rack bar is pressed toward a pinion by a spring 22 where a rack bar supporting surface 23 of a york 20 comes in contact with the rack bar while a rack bar supporting surface 24 of a roller 21 is apart from the rack bar allowing the rack bar to be supported only by the york 20. When the rack bar 13 is subjected to a high load, the rack bar moves overcoming the spring (22) force in such a way that it separates from the pinion. Then, it comes in contact primarily with the rack bar supporting surface 24 of the roller 21 allowing it to be supported primarily by the roller.

Conventionally, this lengthening means has been used to bring the support into frictional contact or rolling on the rack bar, and to transfer these frictional or rolling agitation contacts to the entire rack bar! Ihl1li
However, in such conventional technology, when the support body is brought into frictional contact with the rack bar, it is difficult to perform full steering even when traveling straight. When the steering wheel slips, the steering efficiency is poor (there was a drawback. When the support body rolls into contact with the rack bar, the entire steering wheel becomes Not only could it not be adjusted properly at 11 o'clock, but the support of the rack bar was also unstable.
