正當電單車市場上三個轆熱潮炒得熱哄哄時，冷不防美國Harley-Davidson主動向傳媒放料，說其實他們早在06年便已提出專利註冊的申請。
有關專利註冊的細節文件請按此觀看。右格是H-D對這份傾斜式懸掛機械設計的扼要描述： |
|
A vehicle including a
frame, left and right wheels, and a leaning suspension system. The
frame defines a longitudinal vehicle axis. The leaning suspension
system includes a transverse beam, left and right damping members,
left and right control arms, and at least one lean actuator. The
transverse beam is coupled to the frame and pivotable about the
vehicle axis. The left and right damping members are pivotally
coupled to the left and right sides of the transverse beam. The left
control arm is pivotally coupled to the left wheel and to the frame,
and the right control arm is pivotally coupled to the right wheel
and to the frame. The lean actuator is pivotally connected between
the frame and the transverse beam. The lean actuator is configured
to extend and retract to tilt the left and right wheels and to lean
the vehicle while cornering. |
