Benefits of technology

This patented technology describes improved methods for making multiple link or tandem type rear suspended vehicles (RV) while also enhancing their flexibility during turns and maneuverabilities. These modifications include changing the length of the tires used within each chain segment, adding elastomeric material around certain points along its edges, creating more stable connections, controlling how much space remains inside the car's interior, preventing deformation under heavy loads caused by uneven road surfaces, and ensures proper functioning of the chassis system. Overall, this innovation enhances performance, efficiency, reliance, ease of use, and overall quality control of these types of cars.

Problems solved by technology

In this patented technical problem addressed in this patents are how to create a more efficient way of controlling the movement of an autonomous car's back wheel without increasing its size while maintaining stability under different road conditions.

Abstract

The invention relates to the technical field of automobiles, in particular to a manufacturing method of a multi-link rear suspension, a multi-link rear suspension and a vehicle. The manufacturing method of a multi-link rear suspension comprises the following steps: according to the existing multi-link rear suspension, the braking simulation test of the multi-link rear suspension model is carried out, and the influence positions on the low-speed bending radius and the high-speed bending radius are found out in the multi-link rear suspension model, and the hard points are marked; the rigidity, stiffness or position of the parts marked with hard points are adjusted, and after the adjustment, the braking simulation test is carried out again to obtain the final optimized multi-link rear suspension model; the multi-link rear suspension is manufactured according to the optimized multi-link rear suspension model, and the multi-link rear suspension is manufactured through the manufacturing method of the multi-link rear suspension to solve the problems of poor turning follow-up performance, large turning radius and poor maneuverability when the vehicle is steered at low speed in the prior art; and vehicles are unstable when they turn the corner at high speed, thus being prone to the technical problems of rear tail flick phenomenon.
