A full-time active suspension system and active control method for a vehicle frame

Abstract

The invention relates to a frame full-time active suspension system. Two main connecting rods are arranged between two tyres (2) of each set of running wheel mechanism, every two main connecting rods are movably connected through a movable connecting device (9), two sub connecting rods (5) of each set of running wheel mechanism rotate vertically by certain dip angles with the corresponding movable connecting device (9) as the axis, in the running process of a car, the car can practically and accurately sense the conditions of the ground in the running process of the tyres (2), an electronic control structure is further adopted, and on this basis, the invention further relates to an active control method based on the frame full-time active suspension system. Through the overall electronic control structure, the tyres (2) are subjected to active adjustment, it is guaranteed that a car chassis (1) is located at the horizontal plane to the largest extent, and stability of the car chassis (1) is improved.

Description

technical field [0001] The invention relates to a vehicle frame full-time active suspension system and an active control method. Background technique [0002] The automobile suspension system refers to a connecting structural system between the body, frame and wheels, and this structural system includes shock absorbers, suspension springs, anti-roll bars, suspension sub-beams, lower control arms, longitudinal rods, Components such as knuckle arms, rubber bushes and connecting rods. When the car is running on the road, it is subject to vibration and impact due to changes in the ground. Part of the impact force will be absorbed by the tires, but most of it is absorbed by the suspension device between the tire and the body; the suspension function is It transmits the force and torque between the wheel and the frame, and buffers the impact force transmitted from the uneven road to the frame or body, and attenuates the vibration caused by it to ensure that the car can run smooth...

AI Technical Summary

Problems solved by technology

The improvement and design of automobile suspension in the prior art, starting from different angles and methods, are mainly reflected in the purpose of shock absorption, cost reduction and service life improvement, but in the actual application process, especially for some special use requirements At this time, the existing technical solutions may not be able to deal with it, such as using the automobile suspension to ensure that the chassis of the vehicle is in a horizontal state to the greatest extent. For this, the automobile suspension system in the prior art is powerless.
