Torsional damper having variable bypass clutch with centrifugal release mechanism

A torsional damper (10) rotatably supported for translating torque between a prime mover and the input of a transmission including a torque input member (12) that is operatively connected for rotation with the power take-off of a prime mover, an output member (14) operatively connected for rotation with the input to a transmission and a plurality of damping elements (16) interposed between the input member and the output member. The damping members (16) act to translate torque between the input and output members and to dampen torsional forces generated between the prime mover and the transmission. A bypass clutch (40) acts to translate torque directly between the input and output members thereby providing a path for partial torque translation that bypasses the damping elements at low rotational speeds of the input and output members. In addition, the torsional damper (10) includes a clutch release mechanism (42) that is responsive to centrifugal forces acting on the torsional damper to disengage the bypass clutch (40) to reduce the torque translated directly between the input and output members at high rotational speeds.

Bicycle suspension system

In a preferred embodiment, an ultra-light weight suspension fork for bicycles that provides smooth action of the suspension system that hitherto has been unachievable. This fork assembly contains a telescoping mechanism located in the head tube of the bicycle that uses linear roller bearings to reduce stiction and prevent torsional losses, but limits weight by only using two such bearings. Side-to-side load is eliminated by the use of two longitudinal members in close proximity to the inner tube of this telescoping mechanism. The telescoping mechanism is coupled to the wheel via an arched single-sided fork crown designed to maintain torsional and braking stiffness. The arched crown contains arches in two dimensions. The fork crown is coupled to the wheel via a shaped fork tube whose wall is thickened while the outside diameter is reduced so that the connection point to the axle mechanism has the same outside diameter as the fork tube thereby enabling significant strengthening of the assembly.
