Front suspension device with breakage ease feature
The granted patent US12043080B2 describes a front suspension device designed for vehicles, featuring a suspension arm that supports the front wheel and connects to the vehicle body. The suspension arm consists of a front arm, which includes a damper support portion, and a rear arm that extends rearward. Notably, the damper support portion is equipped with a breakage ease portion intended to facilitate the controlled breakage of the suspension arm under stress. This design aims to enhance safety by allowing the suspension arm to fail in a predictable manner, thereby potentially reducing damage to other vehicle components during an impact.
Further details of the suspension device include a hole in the damper support portion that engages the damper, with the breakage ease portion strategically positioned above and below this hole. The design incorporates a groove-shaped breakage ease portion, which is recessed in the vehicle's longitudinal direction. Additionally, the rear face of the front arm is described as having an arch shape that curves towards the front of the vehicle. The patent also specifies that the suspension arm is formed through a forging process, which may contribute to the strength and durability of the component. Overall, the claims outline a sophisticated approach to vehicle suspension design, focusing on both performance and safety.
