GSwing multilink DGP front suspension

grabcad

This is a customized multilink/double wishbone front suspension inspired by Mercedes Benz C-Class (W202). The term "DGP" or "Dual Gelenk Prinzip" refers to the suspension's unique construction, found in vehicles like Audi A4, A6, and A8. The geometry is designed for optimal steering mechanism, camber, toe-in/out, and track characteristics. The DGP design offers improved self-steering capabilities compared to traditional double wishbone suspensions. Adjustments can be made using steering track rods and an eccentric part in the lower swingarm. Constraints are set at Angle4 for suspension movement and Angle7 for steering mechanism. A basic animation is available on Coub (http://coub.com/view/cqf45). The steering mechanism uses a recirculating ball steering gear, while the main bearing is a 3rd generation suspension design. The damper is similar to the C-Class, and the spring is adjustable in assembly context. Ball joints are custom designs. Casted parts may not have perfect drafts and rounds. Connections to the chassis/body use sheet metal "eyes." This project was created during a university semester, using Solidworks 2015 SP2 for modeling, Keyshot 5 for rendering, and SW for screenshots. All files are available in .step, .x_t parasolid formats, and non-slick tire renderings are provided to aid understanding. The author hopes you enjoy the project and encourages feedback and thumbs up. Gergő Farkas
