Plastic Suspension and EV Chassis... Hyundai Mobis' New Module Technology

Module New Technology Performance Sharing Meeting Held
Showcasing 22 Module New Technologies

Hyundai Mobis unveiled research and development achievements related to automotive module technologies, including suspension systems made of special plastic materials and chassis specialized for electric vehicles.

On the 11th, Hyundai Mobis held a 'Module New Technology Achievement Sharing Meeting' at its Uiwang Research Center in Gyeonggi Province to share R&D results of the three major automotive modules?chassis, cockpit (driver's seat), and front-end modules?with customers and partners. Automotive modules refer to medium-to-large components integrating dozens to hundreds of parts by function.

At this event, Hyundai Mobis showcased a total of 22 new module technologies. Among them, 12 were domestically first-introduced module technologies, including a suspension system that improves ride comfort by utilizing special plastic materials. Notably, a product applying lightweight polymer composite materials to the suspension, which constitutes the chassis module, attracted attention. The chassis module is a large component integrating braking, steering devices, and suspension, serving as a support structure under the vehicle. The suspension is a device that absorbs shocks from the road surface.

Hyundai Mobis developed a plate-shaped spring made of new materials to replace the metal coil spring. The suspension applying this spring improves lateral stiffness, which resists forces pushing side to side during rotation. It reduces the weight of the chassis module and enhances ride comfort.

They also introduced a chassis module specialized for electric vehicles. Through design optimization, additional space was secured for mounting the battery under the vehicle, contributing to improved driving range.

The 'cockpit' module, which refers to the entire driver's control area, was expanded with various convenience features. These include technology that automatically adjusts lighting based on passenger emotions and an electrically operated glove box that opens and closes with just a finger touch.

Jongseong Park, Executive Director of Hyundai Mobis Module Research Lab, said, "We are focusing our R&D capabilities on modules for purpose-built mobility (PBV) and electric vehicles, which are expected to have diverse customer demands, as well as element technologies linked to autonomous driving."
