Automotive pitman arm

Abstract

(1) This article is related to steering in automobiles. (2) When the steering wheel of an automobile is turned, the article rotates (swings) around a pivot shaft located at its base end via a gearbox. The base end of a steering drag rod (more precisely, a steering drag rod end) is connected to the tip of the article, and the tip of the steering drag rod is connected to a first knuckle arm attached to the wheel hub of the left (right side as viewed from the front) wheel. A tie rod also connects a second knuckle arm attached to the wheel hub of the left (right side as viewed from the front) wheel and a knuckle arm attached to the wheel hub of the right (left side as viewed from the front) wheel. (3) The automobile is steered as follows: When the steering wheel of an automobile is turned, the article rotates (swings) around the pivot shaft, causing the steering drag rod to move approximately along its own length, changing the orientation of the left wheel hub. This also causes the tie rod to move approximately along its own length, changing the orientation of the right wheel hub. Thus, the direction of the tires on both the left and right sides changes based on the rotation of the steering wheel, changing the direction of travel of the vehicle. (4) In an automobile, the axles (axle tubes) are connected to the vehicle body by a suspension (suspension mechanism) so that they can be raised and lowered relative to a neutral height position. This article is suitable for use when the vehicle body (its neutral height position) has been adjusted in advance to be higher than its original height (both the front and rear axles are lower than their original height relative to the vehicle body).
