Problems solved by technology

[0010] The present invention aims at that the automobile steering mechanism in the prior art cannot guarantee that the rotation angle relationship of the left and right front wheels fully conforms to the Ackermann principle, thus causing a certain slippage between the wheels and the ground during the steering process of the automobile, which affects the Stability durin

Embodiment Construction

[0024] like figure 2 Among them, the automobile steering mechanism of the present invention includes a steering wheel 10 and a straight tie rod 9. The direction of movement of the straight tie rod 9 is fixed, usually perpendicular to the frame 6, and one end of the straight tie rod 9 is connected to the steering wheel 10. The pull rods 9 are connected by an existing rack and pinion mechanism (not shown), so that the steering straight pull rod 9 obtains a thrust along the bar direction.

[0025] The other end of the steering straight rod 9 is rotatably connected to one end of the steering knuckle arm 8, and the other end of the steering knuckle arm 8 is rotatably connected to the left trapezoidal arm 7. Between the steering straight rod 9 and the steering knuckle arm 8, the steering knuckle A rotating pair is formed between the arm 8 and the left trapezoidal arm 7 to transfer the thrust generated when turning (rotating the steering wheel 10); The other end of the arm 7 a...

Abstract

The invention provides an automotive steering mechanism which comprises a steering wheel and a steering drag link, wherein one end of the steering drag link is connected to the steering wheel. The mechanism provided by the invention is characterized in that the other end of the drag link is rotatably connected to one end of a steering knuckle arm; the other end of the steering knuckle arm is rotatably connected to a left trapezoidal arm; a trapezoidal structure or a rectangular structure is composed of a steering tie rod, a right trapezoidal arm, a frame and the left trapezoidal arm which arerotatably connected with one another; a slidable sleeve is arranged on the right trapezoidal arm; a roller is arranged on the sleeve; the roller is arranged in a fixed sliding slot; and when the roller moves in the sliding slot, the sleeve and the right trapezoidal arm are driven to move or rotate correspondingly. The automotive steering mechanism provided by the invention has the advantages thatthe limited motion of the roller in the sliding slot is utilized to ensure that the turning angles of left and right front wheels fully meet Ackermann steering characteristics in the steering process, the theoretical error is zero, pure rolling is realized, the stability of an automobile during steering is enhanced and the service life of a tire is prolonged.

Description

technical field [0001] The invention relates to a steering device of an automobile, in particular to a steering mechanism matched with a non-independent suspension of the automobile. [0002] Background technique [0003] The automotive mechanical steering system is composed of three parts: the steering control mechanism, the steering gear and the steering transmission mechanism. According to the position of the steering gear and the type of steering wheel suspension, the composition and arrangement of the steering transmission mechanism are divided into the steering transmission mechanism used with the non-independent suspension and the steering transmission mechanism used with the independent suspension. What is discussed here is the steering transmission mechanism used with the non-independent suspension. The steering transmission mechanism transmits the force and motion output by the steering gear to the steering knuckles on both sides of the steering bridge, deflects...
