LEAD-OUT TYPE INDEPENDENT SUSPENSION WITH MULTIPLE SUPPORTING POINTS

摘要

Disclosed is a lead-out type independent suspension with multiple supporting points, comprising an upper fork arm (1), a lower fork arm (2), elastic members (3), a damper (4) and a fork arm positioning shaft (5), wherein the upper fork arm (1) and the lower fork arm (2) are A-shaped structural components, the front ends of the upper fork arm (1) and the lower fork arms (2) are respectively connected to an upper hanging point and a lower hanging point of a vehicle wheel (C) via master pins (B), the rear ends of the upper fork arm (1) and/or the lower fork arms (2) are connected to a vehicle frame in different damping manners, and the damper (4) is mounted on an upper part of the front end of the upper fork arm (1). The upper and lower fork arms of the independent suspension construct reasonable vehicle supporting shaft points and transferring components, by using a lever, a torsion bar and the principle of moment of force, enables the shaft hanging points of the upper and lower fork arms to absorb a borne elastic force by means of a retracing force and the arm of a force or by changing directions, so as to be configured that multiple points support multiple elastic members so as to realize multipoint decomposition of the force sustained by the vehicle wheel to increase an average driving speed. The increase in the number of elastic members and the reasonable arrangement thereof can lower the height of the vehicle, and further optimize the space usage, thereby improving the stability and the running smoothness of the vehicle.
