Abstract
Suspension apparatus (10) for the front end of a motorcycle, bicycle, or like vehicle (11), having a brake (12) on the front wheel (13), comprising a suspension device (14) comprising a pair of telescopic members (27,28) connected to permit relative movement between the frame (15) of the vehicle (11) and the axle (16) of the front wheel (13), a linkage (17,18,20) and a hydraulic cylinder (19) for converting friction force (at 17) from any substantial braking (at 12) of the front wheel (13) into an approximately proportional hydraulic force (at 21), and fluid connecting lines (22,24) with adjustable damping means (23) for applying the hydraulic force (from the fluid 21) to the suspension device (14), at an end surface (29) of a piston (35), so as to oppose and at least largely counterbalance the inertial force thereto resulting from the braking action, and thus to at least largely eliminate diving by the front end of the vehicle (11) when the brake (12) is applied.
