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 friction damping system for use in a system having at least one of a pair of sliding elements. The friction damping system has a friction producing element (44) positioned between the sliding elements (42, 48) such that at least one of the sliding elements rubs against the friction producing element to generate friction and thereby damp the relative sliding movement of the sliding elements. The friction producing element may be provided in a housing that is fixed to one of the sliding elements with the friction producing element facing and contacting the other sliding element. The friction damping system may further be designed to provide directional sensitivity such that damping of movement of the sliding elements in a first direction is greater than damping of movement in a second direction opposite the first direction. Such directional sensitivity may be accomplished by angling one of the surfaces (150) against which the friction producing element moves during sliding movement of the sliding elements.

摘要： Shock absorbing fork, especially a front fork (1), for a two-wheeled vehicle, particularly a bicycle, of the type having a pair of telescoping struts (3) and a hydraulically damped shock absorbing arrangement (15) disposed within each of the telescoping struts (3), the shock absorbing arrangement (15) having a piston (16) which divides a hydraulic fluid containing cylinder (19) into upper (21) and lower (22) chambers, a valve (24) regulating flow of hydraulic fluid through the piston (16) between the upper (21) and lower (22) chambers, and a piston rod (25) connected to the piston (16). Among the improvement of the invention is the provision of a spring (S) for absorbing shocks that acts on the piston (16) of the hydraulic shock damping arrangement (15) upon compression of the telescopic struts (3), and a location sensitive flow control arrangement (37) having a flow path (F) extending between opposite sides of said piston (16) and a flow adjusting element (39) which is displaceable into and out of said flow path (F) as a function of the extent which the spring (S) is compressed by compression of the telescopic struts (3).

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： An adjustable fluid damping system (24) for use in a suspension system that undergoes compression and rebound. The fluid damping system (24) permits independent adjustment of compression and rebound damping by providing separate compression and rebound damping circuits. Each circuit has an inlet (42, 52) through which damping fluid flows during damping, and an adjuster that adjusts the degree to which the inlet is open and hence damping through that flow path. The compression and adjusters are selectively and independently coupled to the same adjuster rod (92) via respective compression and rebound couplers (94, 96). The adjuster rod (92) can be coupled to only one of the couplers (94, 96) at a time. Rotation of the adjuster rod (92) by means of an adjuster knob (62), which can be pulled outward or pushed inward to engage one of the compression and rebound couplers (94, 96), causes rotation of the coupler coupled thereto and axial movement of the respective adjuster to modify damping though the associated damping circuit.

摘要： A lightweight low cost damping assembly having a piston rod (10) on which a piston (40) is formed such that fastener elements are not needed to secure the piston onto the piston rod. Preferably, the piston rod is formed by chrome plating the exterior of a tubular steel rod except at a piston attachment portion. The piston attachment portion is specially shaped such that the piston may be formed threon and coupled thereto by the inter-engaging of the piston with the shape of the piston attachment portion. Most preferably, the piston attachment portion is in the form of shallow grooves, knurls (44) or dimples in the exterior of the piston rod and the piston is injection molded thereon. The material of the piston molds itself into the shape of the piston attachment portion, thereby resulting in a secure coupling between the piston and the piston rod.

摘要： A suspension assembly (10) that is formed of an essentially horizontal swing arm (SA) which is pivotally attached at one end to the underside of a bicycle frame (F) by a pair of short links (L1, L2) and which carries the rear wheel (5) at an opposite end. The geometry of the suspension assembly (10) is designed to produce a substantially straight line trajectory of the rear wheel in an upward and rearward direction at an angle that is preferably 20-30 DEG with respect to a vertical line through the wheel axis of rotation to increase traction, making the acceleration forces apply an upward vertical force component to the frame, and a downward component to the frame under braking, independent of wheel position, that reduces rear frame lift (pitch). Furthermore, to obtain a constant pedal "feel", the suspension geometry is also designed so that the maximum vertical height movement of the pedal crank axis of rotation can be kept to less than 5 % of the vertical wheel travel (e.g., a. 25" crank axis height increase for a 4" vertical wheel travel). The suspension (10) is designed to attach to a standard frame (F) leaving room for mounting of the derailleur between the frame and the rear wheel. In a particularly preferred form, the swing arm assembly is provided with a tubular derailleur mount and an upper tube to which the rear wheel brake assembly can be mounted.
