Steering mechanism of riding lawn mower

Abstract

The present disclosure relates to a steering mechanism of a riding lawn mower, which comprise: a steering shaft, one end of which is connected with a steering wheel, and the other end of which is rotatably connected with a frame, wherein a steering gear is coaxially provided; a steering plate, which is rotatably connected to the frame and is provided with an arc-shaped tooth part engaged with the steering gear, wherein the center of a circle of the arc-shaped tooth part is located at the rotating center of the steering plate; a first steering knuckle and a second steering knuckle, which are rotatably connected to the frame and rotate synchronously with respect to the frame through a linkage structure; a steering knuckle arm, which is connected with the first steering knuckle and rotates synchronously with respect to the frame; and a connecting rod, one end of which is hinged with one end of the steering plate far away from the arc-shaped tooth part, and the other end of which is hinged with the rotating distal end of the steering knuckle arm. As such, the pure mechanical structure combination of the steering wheel, the steering shaft, the steering plate, the connecting rod and the steering knuckle arm is used, which directly transmits the rotary operation of the steering wheel to a turning wheel, so as to realize steering. The steering mechanism is simple and compact in structure, high in reliability and low in cost.
