  • Patent number: 8967630
    Abstract: The present invention is a system for adjusting the height of vehicles that have coil spring suspensions. The invention may be added to existing vehicle suspensions without the need to remove and replace the existing vehicle suspension components. The invention includes cylinders, pistons, seals, dust shields, pressure pump(s) and storage tank(s). It also may optionally include electronic hardware, such as, an electronic controller and software, to control the functions of the system and sensor(s) which detect ground clearance and speed. The invention may be operated manually by a vehicle driver through push buttons, which may operate through the vehicle's existing cruise control buttons. Alternatively, the system can be automated through an electronic control unit (ECU) to avoid collision with obstacles in the vehicle's path.

  • Patent number: 8061697
    Abstract: A rotatable wheel having a rotary shock absorber coupled on an axle and between a disc brake rotor and the rotatable wheel, for providing enhanced suspension. The rotary shock absorber consists of an air-tight hollow disc structure filled with lubricant, the disc structure further having a central circular opening, a sealing plate coupled to and sealing the central circular opening on one side, a sealing boot portion coupled and sealing the central circular opening on the other side, and a circular hub portion nesting inside the hollow disc structure. The hub portion further has six circular through holes, one or more identical helical springs nested firmly inside each of the six circular through holes, and six lug bolts each having two threaded ends and a smooth body. Each of the six lug bolts is further coupled rigidly and perpendicularly at the center of each of the two corresponding helical springs and secured on both ends at each side of the hollow disc structure.

  • Patent number: 7891645
    Abstract: An adjustable coil spring system placed within a leg of a vehicle such as a mountain bicycle fork. The spring system comprises an adjustable first soft spring seated on top of a second firm spring having greater length than the first soft spring. A coupler assembly is positioned between two springs comprised of a threaded bolt threadedly received within a coupler. A spring adjustment mechanism may comprise a knob connected to the threaded bolt through a non-round shaped shaft, wherein the threaded bolt is disposed within the first soft spring. As the knob rotates, the coupler is moved up along the threaded bolt, decreasing the length of the first soft spring, thereby increasing firm spring characteristics of the spring system. As the knob rotates in an opposite direction, the coupler moves down, increasing the length of the first soft spring, thereby increasing soft spring characteristics of the spring system.

  • Patent number: 7600617
    Abstract: An apparatus for controlling relative movement between two interconnected bodies includes a first end cap, a second end cap having an opening, a sleeve interconnecting the end caps to define a chamber between the sleeve and the end caps, a piston assembly including a piston rod extending through the opening of the second end cap, a piston connected to the piston rod, received in the chamber to define at least two fluid chambers on opposed sides of the piston, and a plurality of rollers carried by the piston for rolling engagement with the sleeve. A fluid flow path provides communication between the fluid chambers and provides a restricted fluid flow rate therethrough to control the rate of fluid transfer between the fluid chambers and permit fluid pressure to increase in a chamber into which the piston is being moved to provide a force on the piston opposing its movement.

  • Publication number: 20090108512
    Abstract: A damper for a torque converter, including: a cover plate for a damper; a turbine hub with a surface; and a pilot element rotationally connected to the cover plate and having a surface slidingly engaged with the surface for the turbine hub. The respective surfaces for the turbine hub and the pilot element are at least partially radially aligned and the pilot element is arranged to center the damper with respect to a longitudinal axis for the torque converter. In some aspects, the pilot element includes at least one axial protrusion engaged with the cover plate. In some aspects, the pilot element is formed of stamped metal. In some aspects, the pilot element is axially stabilized with respect to the turbine hub and the cover plate. In some aspects, the pilot element includes at least one radial protrusion slidingly engaged with a radial surface for the turbine hub.

  • Patent number: 7520494
    Abstract: A spring element with a hydropneumatic strut are positioned between the bogie and the body of a rail car, with the strut having a sliding piston in a cylinder, whereby the piston or the cylinder can be connected with the bogie and the other component can be connected with the body, and the piston area of the cylinder is connected with a hydraulic accumulator. A strut that is easy to service and maintain and does not accumulate any appreciable amount of dirt is created by virtue of the fact that the hydropneumatic strut has a hydraulic height regulator valve or a height sensor connected or connectable with a feedback loop, whereby the position of the piston in the cylinder can be adjusted or determined.
