Non-independent suspension adopting oblique leaf springs

The invention relates to a non-independent suspension adopting oblique leaf springs and belongs to the technical field of automotive engineering. The suspension comprises a frame, integral axles and two suspension devices on two sides of the frame, wherein each suspension device comprises four oblique leaf springs, axle connecting components, a wheel and frame connecting components, 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. The non-independent suspension is simple in structure and reasonable in arrangement; four parallel leaf springs can more effectively bear and buffer impact; compared with a conventional longitudinal leaf spring suspension, the suspension adopting the oblique leaf springs has excellent bearing capability and reliability, the positional parameter variable quantity of wheels can be reduced, the bearing center distance of the two sides is increased, the wheel steering range is increased, and a whole automobile has better low-speed flexibility.
