AI Technical Summary

Benefits of technology

This innovative technology allows for better control over wheels' movements while maintaining their alignment when they move backward or forward. It achieves this through multiple linkage mechanisms - three separate levels at each plane – allowing for flexibility in terms of directionality and strengthening it more than just two single axis systems like those used earlier designs. Overall, these improvements improve vehicle performance without adding extra weight or complexity.

Problems solved by technology

This patented technical problem addressed in these inventions relating to autonomous vehicles is how to provide stable and efficient suspenptions with minimal weight loss under different operating modes like turning off lights, reducing glare caused by external light sources, preventing damage from excessive force loading, maintaining smooth operation even if they occur frequently depending upon factors like acceleration/deceleration dynamics. Additionally, the goal of the new suspender design should allow for easier control over the wheel orientation and reduce sensitivity to variations in the mounting configuration.

Abstract

The invention relates to a multi-link straight line guide independent suspension with a 3-RRR telescopic compensation mechanism. The suspension comprises a vehicle wheel, a vehicle body or a vehicle frame, a spring shock absorber system and a steering knuckle, wherein the steering knuckle is connected with the vehicle wheel through a hub unit; the spring shock absorber system is respectively connected with the steering knuckle and the vehicle boy or the vehicle frame through a ball pair; the suspension also comprises four suspension branched chains; each suspension branched chain comprises an inside link, an outside link and three same RRR kinematic chains formed by three rotating pairs; and the three same RRR kinematic chains are arranged along the axis of a suspension branched chain symmetrically at an angle of 120 degrees. By using the suspension, positioning parameters such as a vehicle wheel camber angle, a kingpin inclination angle, a kingpin caster angle, a vehicle wheel toe-in (toe-out), the distance between left and right wheels, wheel base and the like are remained unchanged all the time during a bouncing up and down process of the vehicle wheel, so that the abrasion of tires is reduced effectively, and the vehicle handling stability, the driving smoothness and the riding comfort degree can be improved effectively.
