Abstract

The invention discloses an output type multi-bearing-point independent suspension, which comprises an upper fork arm, a lower fork arm, elastic elements, a shock absorber and fork arm-positioning pivots; the upper fork arm and the lower fork arm are A-shaped structural parts, the front ends of the upper fork arm and the lower fork arm are respectively connected with the upper suspension point and lower suspension point of a wheel through main pins, the shock absorber is mounted on the top of the front end of the upper fork arm, and the rear ends of the upper fork arm and the lower fork arm are connected with a chassis through the elastic elements. A corresponding available space is expanded around the upper fork arm and the lower fork arm, reasonable bearing pivot points and transfer parts of the chassis are structured, the lever principle, the torsion bar principle and the principle of moments are utilized, so that double-fork arm pivotal suspension point motion can absorb bearing elastic force by means of returning force and the arms of force or direction change, the conventional one-point supporting elastic element is changed into the multiple multi-point supporting elastic elements, consequently, the force applied on the wheel is decomposed by multiple points, and thereby average running speed is increased. The increase in the number of the elastic elements and the reasonable arrangement of the elastic elements can reduce the height of a vehicle, optimize space utilization and improve the stability and running smoothness of the vehicle.

Description

technical field [0001] The invention relates to an applied part of an automobile chassis, belongs to the technical field of passenger cars and commercial vehicles, and is an innovative automobile suspension system. Background technique [0002] Suspension system is the general term for all transmission connection devices between the frame (axle) and the wheels of the car. The impact force of the car body and attenuate the vibration caused by it, so as to ensure that the car can run smoothly. [0003] Early automobiles mainly used leaf springs as the non-independent suspension of elastic elements. With the development, the elastic elements also developed from leaf springs to coil springs, torsion bar springs, air springs, rubber springs and oil-gas springs. Existing high-end vehicles mostly use independent suspensions, such as wishbone, trailing arm, single cantilever, candle, McPherson, multi-link and active suspension. [0004] Double wishbone independent suspension is a ...
