    Abstract: A suspension device for a handcycle has a first frame member and a second frame member pivotally coupled to the first frame member. A shock absorber is disposed between the first and second frame members. A lever assembly is disposed between the first and second frame members to transfer motion of the second frame member into the shock absorber. The lever assembly includes a lever pivotally coupled to the first frame member. The lever includes first and second arms coupled at an angle which allows motion of the second frame member to be directed into the shock absorber. The lever assembly is configured to transfer a vertical motion of the second frame member into non-vertical motion directed into the shock absorber. The suspension device further includes a third frame member. The first and second frame members are rotationally coupled to the third frame member.

In this way, the primary and auxiliary fasteners may cooperate to permit the upper member to selectively pivot and lock at alternate positions relative to the lower member.

    Abstract: A damping force generator for a hydraulic shock absorber featuring an increased deflection (bending) characteristic of a damping valve to widen the adjustable range of a damping force. In a damping force generator (70) for a hydraulic shock absorber, the damping valve (80) undergoes deflections with boundaries (71C) between secured portions (71A) and recessed portions (71B) of the valve seat (71) as supporting points K, and inner and outer peripheries of the damping valve (80) are disposed on an outside of line segments L each connecting two circumferentially adjacent supporting points K, K of the valve seat (71).

  • Patent number: 8543291
    Abstract: A wheel suspension system for a three-wheeled motorcycle or “trike” includes parallel wheels mounted on vertically pivoting suspension arms governed by hydraulic pistons. The pistons have upper liquid reservoirs that are interconnected through a valve system, which interconnects the upper reservoirs when the trike is in motion, allowing opposing vertical wheel movements when banking through turns, and prevents liquid exchange when the trike is stopped, thereby holding the motorcycle upright, Embodiments include a manual and/or automatic valve control. A threshold switching speed for an automatic controller can be factory set and/or user adjustable. The pistons can include directly interconnected lower fluid reservoirs. A shock-absorbing reservoir can allow transient vertical movement of both wheels to absorb shocks. A cover system can emulate the appearance of saddle bags and can appear to be covering only a single wheel.

  • Patent number: 8528445
    Abstract: A remote control for a shock absorber has a gripping body with a first positioning element, a pivoting handle and a positioning assembly. The pivoting handle pivotally connects with the gripping body and has a proximal part and a distal part. The proximal part has an abutting surface facing and selectively abutting the gripping body and a core-fastening hole corresponding to the passing hole of the gripping body. The distal part has a communicating recess formed longitudinally through the distal part and also formed in a bottom of the distal part. The positioning assembly is movably mounted in the communicating recess and has a second positioning element exposed from the bottom of the distal part and corresponding to and detachably engaged with the positioning assembly. A rider is able to conveniently control a shock absorber during riding by using the remote control so that facilitates riding.

  • Patent number: 8528927
    Abstract: A steering apparatus for a vehicle includes a stem pipe disposed in a head pipe by upper and lower bearings interposed therebetween, a seal member for covering the upper bearing, and bottom and top bridges mounted on lower and upper ends of the stem pipe, respectively. A single fastening bolt, having a step formed between a head and a threaded surface thereof, is fitted in a pipe insertion hole of the top bridge and the upper threaded portion of the stem pipe. The stem pipe is firmly tightened and supported by a stem pipe slot-tightening mechanism of the top bridge. The fastening bolt is tightened by only a tightening force required to keep the fastening bolt from loosening. Also, a number of components required for the inventive steering apparatus is reduced, since an additional component, previously used for preventing loosening of a fastening bolt, is made unnecessary.

  • Patent number: 8528926
    Abstract: A bicycle is provided having a unitary steering tube-crown member and a unitary crank arm-spindle member. A multistage aluminum 3D forging process is used to form the unitary members. This may allow the fabrication of components with substantially hollow interior areas to reduce weight, reduce part count while maintaining high strength and ductility. The multistage 3D forging process provided also allows the combination of multiple components into a single unitary part.

  • Patent number: 8511700
    Abstract: A master device for a closed hydraulic system of handlebar-steered vehicles includes a basic body and a pressure chamber in which, in the event of actuation of the master device in order to actuate a slave device, hydraulic fluid is placed under pressure. The master device includes a hydraulic line connecting element having a connecting piece for connecting a hydraulic line and a thread section for screwing into the basic body. An air bleed opening bleeds the hydraulic system. The hydraulic line connecting element and the basic body form a valve that closes the connection between the pressure chamber and the air bleed opening when the hydraulic line connecting element is fully screwed in to the basic body.

    Abstract: A bicycle air shock absorber assembly that includes a hollow piston rod that is telescopically associated with a hollow compression rod. The piston rod and compression rod are positioned within the casing of the shock assembly. A piston is supported by the piston rod and divides the volume of the compression rod to form a negative air spring chamber and a positive air spring chamber that includes the volume of the piston rod. An optional coil spring is positioned within the casing and contributes in parallel with the positive air spring chamber to resist compression of the shock assembly.
