Steering arm assembly, steering mechanism and multi-axis steering wheel heavy vehicles

摘要

This application concerns a steering arm assembly. the steering arm assembly comprises a steering arm body, a first rotational connecting part and a second rotational connecting part, with a first end and a second end of the steering arm body being fixedly connected, respectively with a first oscillator arm and a second oscillator arm; the first rotational connecting portion and the second rotational connecting portion are respectively connected with the first end and the second end of the steering arm body, and the steering arm body is configured to rotate relative to the first steering part. rotational connection and the second rotational connection part, with the steering arm body being removably located next to a mounting bracket through the first rotational connection part and the second rotational connection part; and the first rotational connecting portion and the second rotational connecting portion including, respectively, a first mechanical shaft housing and a second mechanical shaft housing, respectively, rotationally located with the steering arm body near the control console. Assembly. The steering arm assembly of this application accentuates the steering arm connection resistance, reduces the cost of consumption and the subsequent maintenance cost. The present application further relates to a steering mechanism and a multi-axle steering wheel type heavy-duty vehicle.
