AI Technical Summary

⚠Technical Problem

Existing suspension systems face challenges with unfavorable lever arms and limited stroke of damping spring assemblies, particularly in vehicles with wider tires, leading to increased forces on the assembly and aerodynamic inefficiencies due to exposed damping components.

⚗Method used

A suspension system design incorporating a rocker arm and adjustable first member that extends the stroke of the damping spring assembly by allowing the rocker arm to rotate with respect to the lower arm, reducing the need for larger components and improving aerodynamics by keeping the assembly outside the vehicle body.

🎯Benefits of technology

The system achieves a longer stroke with reduced overall dimensions and weight, enhancing wheel control and aerodynamics while allowing for adjustable geometry to optimize performance and clearance.

Abstract

Described is a suspension system for a vehicle (100) comprising a frame (101) and at least one hub-holder (102), comprising an upper arm (2) and a lower arm (3), both linked to said frame (101) by a respective first end (2a, 3a) and by a respective second end (2b, 3b) to the hub-holder; a damping spring assembly (4) linked to the frame (101) by a first end (4a); a rocker arm (5) linked to a second end (4b) of the damping spring assembly (4) by a first joint (7), to the frame (101) by a second joint (8) and pivoted to one between said upper arm (2) or said lower arm (3) by a third joint (10) located between the first and the second joints (7, 8) along the rocker arm; the first, second and third joints respectively define a first rotation axis (R4-5), a second rotation axis (R5) and a third rotation axis (R5-9).
