Automotive double-front-axle structure adopting non-independent oblique leaf spring suspensions

An automotive double-front-axle structure adopting non-independent oblique leaf spring suspensions comprises a frame, a first front axle, a second front axle and a steering system, wherein each of the two front axles comprises two oblique leaf spring suspensions, an integral axle and a trapezoid steering mechanism; each oblique leaf spring suspension comprises four oblique leaf springs, the first oblique leaf spring and the fourth oblique leaf spring are symmetrical about the axle, and the second oblique leaf spring and the third oblique leaf spring are symmetrical about the axle, and an intersecting line of longitudinal symmetric center surfaces determined by the first oblique leaf spring and the fourth oblique leaf spring is parallel to or collinear with an intersecting line of longitudinal symmetric center surfaces determined by the second oblique leaf spring and the third oblique leaf spring. Compared with a conventional double-front-axle structure adopting non-independent longitudinal leaf spring suspensions, the automobile double-front-axle structure has high bearing capability, the positional parameter variable quantity of wheels can be reduced, the bearing center distance of the leaf springs is increased, and the abnormal wear of the tires is reduced; the wheel steering range is increased, and a whole automobile has better low-speed flexibility.
