摘要： A mounting mechanism (10) for mounting a disk brake mechanism (18) to a bicycle. The mounting mechanism (10) includes an elongated mounting bracket (30) that is mounted adjacent the bicycle wheel assembly. Preferably a first end of the bracket (30) is coupled to the wheel dropout (12) of the frame (16) and a second end of the bracket is coupled to a portion of the bicycle frame, such as the seat stay (14). A mounting band (52) or other similar coupling element may be used to couple the second end to the frame (16) such that the integrity of the frame (16) is not compromised. The disk brake component (18) to be mounted adjacent the wheel is coupled to the mounting bracket preferably between the ends of the bracket (30).

摘要： A suspension system (12), particularly for a pedal-driven vehicle, comprising a telescoping strut having first and second telescopingly and coaxially engaged members (16, 18), and having a damping system (10) comprising a damping fluid (52), a damping piston (40) connected to a piston rod (30), an inertia-activated compression fluid flow control mechanism (79) and a pressure-activated compression fluid flow control mechanism (70) disposed in the first telescoping strut. The inertia-activated compression fluid flow control mechanism comprises a valve body biased by a valve spring (86) into a first position over a radial groove (94) formed on the piston so that the valve body prevents fluid flow through an inertia-activated compression fluid flow circuit in response to force inputs imparted to the vehicle frame. The valve spring (86) and valve body are connected to the piston rod (30) which extends into the first telescoping member (16) and is attached to the vehicle wheel, such that the valve body may be moved into a second position permitting fluid flow through the inertia-activated compression fluid flow circuit by force inputs imparted to the vehicle wheel. Because the inertia-activated fluid flow control mechanism is inertia-activated and not pressure-activated, a force impact imparted to the vehicle wheel results with fluid flow through both the pressure-activated and inertia-activated flow circuits, whereas force inputs such as from pedalling, weight shifting and acceleration or deceleration forces do not result in flow through the inertia-activated circuit. The suspension system therefore resists the absorption of pedal drive energy, provides a ride-leveling effect, and provides a broad range over which the damping system may be adjusted.

摘要： A suspension system (10) for a bicycle or other vehicle or apparatus, the system including at least one telescoping strut comprising a first telescoping member (12) and a second telescoping member (14), the first and second telescoping members being telescopingly and coaxially engaged with each other so that the strut is compressible by relative movement of the telescoping members toward each other and expandable by relative movement away from each other. A piston (16) may be interconnected with the second telescoping member and slidably positioned within the first telescoping member. The piston separates a primary compression spring chamber into two gas chambers (30, 34) connected by an adjustable port, whereby compression or expansion of the strut creates a damping force that resists such relative movement of the telescoping members, resulting in the primary compression spring having a frequency-sensitive spring rate. The crack force, spring rate and other characteristics of the suspension system may be adjusted using a piston location adjuster to adjust the piston height, and/or a negative preload spring to apply a compressive preload force to the telescoping strut.

摘要： A suspension system having first and second elements telescopingly engaged and being biased apart by a positive spring (16), such biasing being counteracted by a negative spring (38). In one embodiment, the positive spring and negative spring are disposed in the first element, which is in the form of a tube, and separated by a damping system (60), and a damping piston (62) is fixed with respect to the first element. In another embodiment in which the suspension system comprises two legs (102) of a bicycle suspension fork (100), a positive spring is disposed in both legs, and a negative spring and damping system are disposed in separate legs. The positive and negative springs preferably comprise air or other gas springs, and the negative spring preferably performs the additional function of resisting top-out impacts.
