Independent front suspension with transversely arranged steel plate spring

Abstract

The invention discloses an independent front suspension with a transversely arranged steel plate spring. The independent front suspension with the transversely arranged steel plate spring comprises a left front shock absorber and a right front shock absorber both provided with a limiting block, left and right steering knuckles, a steel plate spring, and a steady rod component, wherein left and right lower swing arms are respectively connected with the left and right steering knuckles through lower swing arm ball pins; the transversely arranged steel plate spring is composed of two transversely arranged upper and lower steel plate springs with variable cross-sections; the middle part of the steel plate spring is connected with a car body; the central line of the steel plate spring is consistent with an X-direction of a wheel center of a wheel; two ends of the steel plate spring are connected with the left and right lower swing arms through a vulcanized rubber component; the shock absorbers are arranged vertically in a front view of a car, inclined backwards in a side view thereof and have an included angle alpha of 2-4 degrees with the axial line. The independent front suspension, disclosed by the invention, has the advantages of compact arrangement, rational structure, relatively low manufacturing and processing cost; the transversely arranged steel plate spring is mutually matched with a single-angle shock absorber, so that the car can achieve relatively ideal comfort level in any load state, good operational stability of a McPherson suspension is continued, and internal space of the car is further maximized; and obvious improvements in the aspects of overall performances, cost and the like are achieved.

Description

technical field [0001] The invention relates to a front independent suspension mechanism of a vehicle, in particular to a front axle independent suspension mechanism of a commercial vehicle such as a traditional McPherson front suspension improved. Background technique [0002] The traditional MacPherson front suspension generally uses coil springs as the main elastic load-bearing elements, and the shock absorbers are arranged in a spatial angle; although its structure is relatively simple, the coil springs require a large space; the load state of the car changes greatly, The working condition of the shock absorber is complicated, and the traditional shock absorber can no longer meet people's requirements for good comfort; moreover, the space angle of the shock absorber increases the difficulty of manufacturing, which is likely to cause inaccurate positioning; the installation positions of the spring and the shock absorber are centralized , there are great requirements on th...
