RAMP CONTROL FOR A FRONT FORK OF A BICYCLE

摘要

A suspension unit for a front fork of a vehicle includes an annular tube. The first tube defines a compression chamber and a damping chamber. A damper includes a first valve allowing gas to variably flow from the compression chamber to the damping chamber and a second valve allowing gas to flow from the damping chamber to the compression chamber. An external adjuster allows a rider to adjust the first valve to improve ride conditions.

1. A suspension unit for a bicycle, comprising:
an annular tube defining a compression chamber; a piston slidingly interfitting with the annular tube and capable of reciprocating with respect to the annular tube, the piston capable of compressing a compressible gas in the compression chamber; a barrier assembly remote from the piston, comprising a damping barrier near one end of the annular tube, the compression chamber being on one side of the barrier assembly and a damping chamber being on another side of the barrier assembly; and a first valve operatively between the compression chamber and the damping chamber and capable of permitting the compressible gas to flow between the compression chamber and the damping chamber; wherein an effective force is applied to a blocker in the first valve, the effective force influencing a threshold level of force of compressed gas in the compression chamber capable of opening the first valve.
