Double-trapezoid broken type steering mechanism

The invention discloses a double-trapezoid broken type steering mechanism used for an independent suspension system. The double-trapezoid broken type steering mechanism comprises a broken type main trapezoid mechanism and an integrated type auxiliary trapezoid mechanism. The double-trapezoid broken type steering mechanism removes motion interference between the suspension system and a steering system and improves steering lightness and operation stability. By the adoption of the double-trapezoid broken type steering mechanism, the ackermann error of the turning angle of a left steering wheel and the turning angle of a right steering wheel can be remarkably reduced, the left steering wheel and the right steering wheel are made to steer around the same instantaneous center, abrasion on tires is reduced, and the service life of the tires is prolonged.
