Introduction

Jun Dai is an inventor based in Shanghai, China, whose work includes vehicle suspension technology. His patent record includes 1 patent concerning a multi-link independent suspension designed to make wheel camber adjustment more efficient.

Latest Patents

Dai’s patent, “Multi-link independent suspension for vehicle, and vehicle,” addresses a challenge in existing multi-link suspensions: their linkages can constrain one another during camber adjustment, reducing adjustment efficiency.

The disclosed suspension includes a subframe, a steering knuckle, a spring control arm, and front and rear upper control arms. The geometry aligns the upper-arm motion centerline with the projection of the spring control arm’s central axis on the XY plane. This arrangement is intended to let the spring control arm adjust the wheel-center camber angle without affecting the upper control arm system.

The steering knuckle rotates about the X axis to drive the tire’s rotation about that axis. The design allows the tire’s camber angle to be adjusted without changing its toe-in angle, reducing the number of linkages affected and simplifying adjustment.

Career Highlights

The available information identifies Dai’s work on this suspension as a notable contribution to vehicle engineering. The invention focuses on linkage geometry and independent control of wheel alignment.

Collaborations

Dai is associated with Nio Technology (Anhui) Co., Ltd. His listed coworkers include Haibo Wang and Dongdong Wang.

Conclusion

Jun Dai’s patented suspension design aims to improve camber adjustment by reducing interference among suspension linkages while preserving the tire’s toe-in angle.
