  • Patent number: 11566681
    Abstract: A spring damper device comprising a directional spring (e.g., coil) having first and second ends, and defining an inner diameter region. A damper (e.g., viscoelastic polymer slug) comprising an element of elasticity configured to be situated within the inner diameter region of the directional spring. In response to a load on the spring damper device, the directional spring operates to compress, and the damper operates to dampen vibration associated with the load. The damper can comprise a viscoelastic damper comprising both an element of viscosity and the element of elasticity. The damper can be substantially coaxially aligned with the directional spring. Spring damper device(s) can be preloaded in a micro adjustment mechanism to account for positional adjustments between two structures (e.g., between a scope and a firearm), such that the spring(s) attenuate a shock impulse event (e.g., when firing), while the damper(s) attenuate vibration (e.g., to prevent damage the scope).

  • Patent number: 8113322
    Abstract: Air suspension systems, devices, apparatus, and methods for allowing motorcycle drivers to increase and decrease compressed air supplies in air suspension devices. Deflating interior air springs/airbags (bladders) inside the devices allows for springs and pistons on shock absorbers in the devices to expand outward separating lower front and rear frame portions which effectively lowers the motorcycle to the ground surface and for the driver to have a firmer ride. Inflating the air springs/airbags (bladders) allows for the springs and the pistons on the shock absorbers in the devices to retract into the devices so that the devices have a more shock absorbing effect giving the rider a smoother ride, which also raises the motorcycles above the ground surface.

  • Patent number: 7128312
    Abstract: An elastomeric spring assembly for a railcar apparatus is disclosed. The elastomeric spring assembly includes an elongated body of elastomeric material having a series of axially spaced members coaxially arranged and wholly embedded within the body of elastomeric material. The majority of the embedded members are configured to resist radial outward movement of said elastomeric material while causing the elastomeric material to react in an axial direction between confronting surfaces defined by the members upon axial deflection of the elastomeric spring whereby enhancing performance characteristics of the spring assembly. A method of making an elastomeric spring assembly is also disclosed.

  • Patent number: 6971640
    Abstract: An elastomeric sway bar bushing provides an improved and secure fit between a retention bracket and a motor vehicle sway bar under extreme temperature and mechanical conditions. Tab sections, ring sections, and a convex stability ridge extend from the bushing and firmly lock the bushing to both the retention bracket and the sway bar while maintaining ease of assembly, minimizing debris buildup, resisting thermal degradation. The ring sections serve an additional sacrificial function and maintain surface contact with the sway bar beyond the limits of the retention bracket.

  • Patent number: 6843352
    Abstract: A shear mount assembly and a compression mount assembly are combined to control ride harshness of a shock absorber. The shock absorber includes a body and a shock rod having a hydraulically sealed portion within the body and a distally extending free portion. A mount assembly is connected at the free portion having both a compression mount and a shear mount therein. The shear mount absorbs low-input vertical loads transferred from the shock rod, and the compression mount limits vertical displacement of the shear mount and absorbs a medium-input vertical load. The shear mount and the compression mount are tuned by selecting the durometer, dimensions, and physical configuration of each mount.

  • Publication number: 20040145098
    Abstract: An energy absorber for use in a fall arrest system is disclosed and comprises a housing, a plunger and a compressible cushion. The housing has a tubular body and an end wall. The body defines a longitudinal axis. The end wall is secured to the body and has defined therethrough an aperture. The plunger includes a head disposed within said body and a rod extending from said head, through the aperture in the end wall, to a terminal end. The plunger is disposed at a rest position, whereat the head is relatively distal to the end wall, and is mounted to the housing for longitudinal movement between the rest position and an extended position, whereat the head is relatively proximal to the end wall. The cushion is disposed within the body between the end wall and the plunger head, for compression by the plunger upon said longitudinal movement thereof.

  • Publication number: 20040113335
    Abstract: An improved airspring assembly includes a collapsible support member disposed within the pressurizable chamber of an airspring having a flexible sidewall. The support member is configured such that it extends and collapses along a longitudinal axis of the chamber responsive to pressurization and depressurization of the chamber, respectively. The support member also is configured such that it retains a substantially rigid outer perimeter, thereby restricting movement of the chamber's flexible sidewall toward the longitudinal axis when the chamber is depressurized. The support member also is configured such that it does not interfere with the full stroke of the airspring.

  • Patent number: 6698780
    Abstract: A computer controlled suspension system is provided for a bicycle, which can effectively absorb shock and provide stability on rough surfaces regardless of the speed of the vehicle. The suspension system has a control unit, a front suspension, a rear suspension, a front wheel terrain sensor, and a rear controller. The rear suspension is selectively adjustable by the control unit to change stiffness of the rear suspension. When the front suspension hits a bump or a depression in the surface of the ground, a signal is sent to the rear controller so that the rear suspension can react appropriately. In one embodiment, a pedaling torque sensor is operatively coupled to the control unit to input a signal that is indicative of pedaling force, and the rear controller adjusts stiffness of the rear suspension in response to the pedaling force via the control unit.

  • Patent number: 6666311
    Abstract: A spring strut support bearing, has a top bearing that can be affixed by its inner ring to the front end of an automobile, e.g. to the end of a piston rod of a shock absorber facing a vehicle body. The inner ring is surrounded by an outer ring with radial clearance; at least one elastic spring element made of rubber-elastic material is arranged in a gap formed by the clearance. The outer ring is disposed in a stationary manner with respect to the vehicle body; and only the component of the loading force of the shock absorber extending through the elastic spring element of the top bearing reaches the vehicle body. The inner ring has on each of its two end faces at least one elastically flexible stop buffer for limiting extreme deflection movements in moving direction of the shock absorber, the stop buffers each having the capability of being brought into contact with counter stop faces.
