  • Patent number: 10155426
    Abstract: The present invention is a system for adjusting the height of vehicles. The vehicle is supported by a hollow cylinder and a piston having an undersized piston skirt is mounted on the suspension system's coil spring, and sealingly slidable within the cylinder bore. When a fluid is introduced into the expandable pressure space between the piston and the cylinder top, the piston and cylinder are forced apart, raising the vehicle. The undersized piston skirt can extend beyond the end of the cylinder, allowing the piston a greater travel length within the cylinder bore. The invention may be operated manually by a vehicle driver through push buttons, which can be the vehicle's existing cruise control buttons. Alternatively, the system can be automated using a control unit to automatically adjust ground clearance to avoid collision with obstacles in the vehicle's path.

    Abstract: Apparatus, systems, and methods for damping movement of a first mass relative to a second mass by magnetically generating induced current are provided. A magnet is coupled to one mass and a nonferrous metallic member is coupled to another mass that moves relative to the first mass. First and second springs are coupled to opposing ends of the magnet, the magnet being positioned between the springs. A guide member channels the magnet as it moves relative to the nonferrous member, the magnet being slidable along the guide member. The magnet is in close proximity to the nonferrous metallic member as the magnet moves. Upon causing movement of the magnet by either mass, the magnet generates an electrical current in the nonferrous metallic member that induces a counter magnetic field that opposes the magnetic field generated by the current to damp movement of the magnet as it moves.

  • Publication number: 20110148066
    Abstract: A vehicle suspension, steering, damping and anti-roll system for a wheeled vehicle. Unlike most previous vehicle suspension and steering systems, this invention uses a rod-in-sleeve design for the front and rear suspension assemblies to allow vertical linear wheel knuckle movement of the wheels. This invention is unusual by using a cable-operated steering system and also by using cables to transfer cable tension from upward wheel movement to remote spring/shock absorber assemblies. Also unique is the use of a spring/shock absorber assembly arrangement that provides both suspension and anti-roll effects for a pair of right and left wheels in the same unit. The rear suspension proposed shares some similarities to the front suspension and consists of a dual rod-in-sleeve design with cables that transfer forces from road bumps to a remote spring assembly.

Compared with a spring formed with a circular-shape cross section, the spring formed with one of foresaid abnormal-shape cross sections has some or all of the following functions: The stroke can be increased under the condition of a same free height; it can be prevented from broken after its load area is enlarged; it can reduce weight under the condition of a same stroke; it can enhance resistance to huge outer stress and thus prolong its service life and it can be received and positioned in a very small space.

  • Publication number: 20080093786
    Abstract: The invention solves the problem of designing and manufacturing springs made of elastic materials, particularly steel springs, with prescribed characteristic (dependence of flex on external load) given by a smooth (i.e. differentiable) non-linear function. The method according to the invention consists in forming an elastic body with suitably shaped regions of diversified stiffness and (possibly) diversified initial internal stresses (this suitable shape of the regions lies at the hart of the invention and is covered by separate patent claims).

  • Publication number: 20080054540
    Abstract: A suspension system including: (a) a suspension spring; (b) a shock absorber; and (c) a generator for generating a displacement force forcing sprung and unsprung members of a vehicle to be displaced toward or away from each other. The generator includes (c-1) an elastic body connected one of the sprung and unsprung members and (c-2) an actuator disposed between the elastic body and the other of the sprung and unsprung members. The actuator includes a motor, and is operable to generate an actuator force based on a motor force generated by the motor, such that the generated actuator force acts on the elastic body and such that the generated actuator force is transmitted to the sprung and unsprung members via the elastic body so as to act as the displacement force. The suspension system further includes (d) a controller for controlling operation of the motor so as to control the displacement force.

  • Publication number: 20080018034
    Abstract: The present invention relates to a shock-absorbing rod for bicycle saddles, which essentially consists of an outer tube and an interior tube, wherein the interior tube is inserted into the outer tube. There is hydraulic oil poured on the outer and interior tubes. Furthermore, a resilient body is arranged in the interior tube to support the piston rod connected to a saddle. Accordingly, the user can feel comfortable, even when he/she rides on an uneven road surface, since the shock-absorbing rod can effectively absorb shocks and vibrations resulting from uneven road surfaces.

  • Publication number: 20070278726
    Abstract: A strut type shock absorber (1) comprises an outer shell (2) and a knuckle bracket (3). A curved portion (4) of the knuckle bracket (3) positioned in close contact with the outer shell (2) comprises a reinforcing flange (7) formed by bending a part of an axial end of the curved portion (4) outward and a no-flange portion (6), both of which are welded onto the outer shell (2). By setting an axial distance (H) from an inflection start point to an inflection end point of the outer circumferential surface of the reinforcing flange (7) to be equal to an axial distance from the inflection start point to the no-flange portion (6), and by forming an insulation portion (9) between the reinforcing flange (7) and the no-flange portion (6), an effectual welding operation and the prevention of molten metal from flowing over the reinforcing flange (7) during welding are realized.

  • Patent number: 6978985
    Abstract: A non-sectional locking buffer device. The device utilizes a screw ascending and descending principle as a buffering function, wherein ball bearings or outer screw grooves are configured on a central shaft of the buffer device to operate in coordination with inner screw grooves or ball bearings configured on an inner wall of a buffer chamber. The inner and outer screw mechanisms rely on slippage of the ball bearings in the screw grooves, to reduce a jolting force from repositioning or returning of an upright support, thereby reducing buffer malfunction.
