Idler rod of steering gear box

Abstract

An idle rod of a steering gear box comprises a ball cup, a ball rod and an intermediary piece. A ball head at one end of the ball rod is connected with a ball socket of the ball cup and can swing or rotate, and the ball head is divided into a first hemisphere part and a second hemisphere part by taking a circle tangent line as a boundary; the intermediary piece is arranged in the ball socket and located between the ball cup and the ball head, the intermediary piece comprises a first lining and a second lining, the first lining is located on the left side of the circular tangent line and wrapsthe first hemisphere part, and the second lining is partially located on the right side of the circular tangent line and wraps the second hemisphere part; and the other part of the second lining is positioned on the left side of the circular tangent line and covers part of the first hemisphere part. Therefore, the tensile resistance effect of the idle rod of the steering gear box is enhanced.

Description

Technical field[0001]The invention relates to a steering power system; in particular, it refers to a steering gear idler rod that can improve the tensile force.Background technique[0002]The combination of a steering gear idler rod (also called inner tie rod end) and a tie rod end (also called an outer tie rod end) is called a side tie rod, which is a part of the steering system. The steering gear idler rod is used to connect the steering rack to the steering rod connected to the wheel, and is one of the important parts of the steering system between the steering wheel and the tire; the steering gear idler rod is mainly used for the rack and pinion in the steering system , Using the circular motion of the pinion gear to transform the force into a level and transmit it to the left and right wheels, and absorb the horizontal and vertical forces during driving.[0003]figure 1 Shown is an existing steering gear idler rod 1, which is disclosed by a ball head holder 2 and a ball rod 3. The ...

AI Technical Summary

Problems solved by technology

[0004] It is true that although the above-mentioned steering gear idler 1 has good transmission performance, only the way that the converging end edge 2b of the ball head seat 2 slightly covers the ball head 3a is obviously insufficient in absorbing the pulling force from the lateral direction during driving. Secondly, the lining Although the sleeve 4 has a bowl-shaped structure, its function is only to strengthen the wear resistance and does not help to provide additional resistance. Therefore, the existing steering gear idler rod 1 is not perfect and needs further improvement.
