Referring to fig. 1-4, the present invention provides a technical solution:
1-an arrangement structure of a knuckle arm 12 for an independent suspension, which comprises a wheel 1, a hub 2, a connecting turn 3, a hub reduction gear shell 4 and a knuckle 5, wherein the wheel 1 is fixedly arranged on the hub 2, the hub 2 is rotatably connected with the hub reduction gear shell 4 through the connecting turn 3, the knuckle 5 is fixedly arranged on the hub reduction gear shell 4, the front axle steering knuckle is characterized in that a steering knuckle arm 12 is fixed on a steering knuckle 5 through a bolt, the steering knuckle arm 12 is hinged with a first rotating rod 11-2, a first rotating rod 11-2 and a second rotating rod 11-3 are fixedly installed on an installation column body 11-1, the installation column body 11-1 is rotatably connected onto an installation seat 10, the installation seat 10 is fixedly installed on a front axle 8, a hinged ball head 9 is fixedly arranged on the end face of the second rotating rod 11-3, and the steering knuckle 5 is hinged with the front axle 8 through a connecting lug 6 and a hinged bolt 7.
Wherein, the first rotating rod 11-2 and the second rotating rod 11-3 are arranged perpendicular to each other. The distance from the hinge center of the first rotating rod 11-2 to the rotation center line is larger than the distance from the hinge center of the first rotating rod 11-2 to the axis of the second rotating rod 11-3 to the knuckle arm 12 and the second rotating rod 11-3, and the first rotating rod 11-2 and the second rotating rod 11-3 are always in a vertical state when the vehicle travels straight. A knuckle arm 12 is disposed forward and upward of the front axle 8.
In use, the steering control lever is hinged to the second rotating lever 11-3, the second transmission force 15 of the steering control lever acting on the hinged ball 9 is perpendicular to the second rotating lever 11-3, as shown in fig. 3, wherein the second transmission force 15 is a vector, when the second transmission force 15 is a negative number, i.e. the direction is opposite, now taking the direction shown as an example, under the action of the second transmission force 15, the mounting column 11-1 rotates counterclockwise, so that the first rotating lever 11-2 acts on the knuckle arm 12 to generate a leftward first transmission force 16, and the first transmission force 16 is perpendicular to the knuckle 5, so as to urge the knuckle 5 to rotate around the central rotation axis 14, thereby achieving the purpose of steering.
And (3) stress analysis: the acting force of the steering control lever, the second transmission force 15, is reduced or enlarged to be the first transmission force 16 due to the length size relation between the first rotating rod 11-2 and the second rotating rod 11-3, the moment acting on the steering knuckle 5 is enlarged due to the fact that L2-19 is smaller than L1-18, and the force of the second transmission force 15 and the first transmission force 16 can be far smaller than that of a traditional steering control lever due to the fact that the first transmission force 16 is perpendicular to the steering knuckle 5, and therefore the effect of more flexible steering is achieved.
