摘要： A head unit system for controlling motion of an object includes an environment sensor and a head unit that include shear thickening fluid (STF) and a chamber to contain the STF. The chamber further includes front and back channels. The head unit further includes a piston housed radially within the piston compartment and separating the back channel and the front channel. The piston includes a first piston bypass and a second piston bypass to control flow of the STF between opposite sides of the piston. The chamber further includes a set of fluid flow sensors and a set of fluid manipulation emitters to control the flow of the STF to cause selection of one of a variety of shear rates for the STF within the chamber to abate an internal factor of concern associated with an internal environment as sensed by the environment sensor.

摘要： A head unit system for controlling motion of an object includes a secondary object sensor and a head unit device that include shear thickening fluid (STF) and a chamber configured to contain the STF. The chamber further includes a front channel and a back channel. The head unit device further includes a piston housed at least partially radially within the piston compartment and separating the back channel and the front channel. The piston includes a first piston bypass and a second piston bypasses to control flow of the STF between opposite sides of the piston. The chamber further includes a set of fluid flow sensors and a set of fluid manipulation emitters to control the flow of the STF to cause selection of one of a variety of shear rates for the STF within the chamber to control motion of the object with regards to a secondary object.

摘要： The present embodiment generally relates to a mechanical assembly which modifies and enhances the performance of a critical portion of the parts which comprise an air spring assembly. A key element common with an air spring assembly is the precharge chamber. This chamber is filled at the factory with compressed gas and along with a floating piston and a piston rod, creates the basic air spring assembly. Although this is a sealed chamber, the potential for air leakage is well documented. The inability to maintain the design gas pressure in the precharge chamber requires the chamber to initially be overcharged to remain functional even with the slow loss of air charge. The present invention demonstrates how the precharge assembly found in all such air springs can be modified and, with the addition of a few parts, be capable of maintaining the precharge pressure at an optimum level.

摘要： An apparatus and system are disclosed that provide position sensitive suspension damping. A damping unit includes a piston mounted in a fluid-filled cylinder. A vented path in the piston may be fluidly coupled to a bore formed in one end of the piston rod, creating a flow path for fluid to flow from a first side of the piston to a second side of the piston during a compression stroke. The flow path may be blocked by a needle configured to engage the bore as the damping unit is substantially fully compressed, thereby causing the damping rate of the damping unit to increase. In one embodiment, the piston includes multiple bypass flow paths operable during the compression stroke or the rebound stroke of the damping unit. One or more of the bypass flow paths may be restricted by one or more shims mounted on the piston.

摘要： A hydraulic damper spool valve (15) includes a pair of resilient energy storage members (47, 49) one of which is disposed between each of a valve spool (39, 41) and a valve body dividing section (27) so as to bias the valve spools (39, 41) in opposing directions to the forces generated by the operating pressures in the hydraulic fluid of the hydraulic damper (1). The valve spools (39, 41) are configured to vary the hydraulic flow restriction between the upper portion (11) and the lower portion (13) of the hydraulic damper (1). A compression hydraulic flow path is structurally separate from a rebound hydraulic flow path to prevent backflow via the other hydraulic flow path during hydraulic flow in either direction, each said flow path communicating with only the at least one shaped aperture (35, 37) adjacent the opposing end of one of the valve sleeves (23, 25).

摘要： Shock absorber comprising a tubular base, a piston, a stem connected to the piston, and a plurality of fluid paths for connecting a working chamber and an accumulation chamber on opposite sides of the piston, one of which provides for a ring-shaped obstructing member arranged about the piston and able to slide along an axial length of the piston. The obstructing member comprises a bush of plastic material, which has a flexible lip portion extending from a rear end of the bush and having a radially outer surface tapered towards the rear end of the bush, the lip portion being adapted to seal against a radially inner surface of the base when the obstructing member is in a closed configuration. A support ring member is adapted to radially engage the lip portion of the bush from within, and to push it against the radially inner surface of the base.

摘要： A valve component includes a first disk-shaped joining part and a second disk-shaped joining part. The first disk-shaped joining part has a first opening and has an elevation in a first region of the first disk-shaped joining part which runs at least partially peripherally around the first opening. The second disk-shaped joining part is joined to the first disk-shaped joining part and has a second opening which together with the first opening defines a channel for flow of a fluid medium therethrough. The second disk-shaped joining part further has a depression in a second region of the second disk-shaped joining part which runs at least partially peripherally around the second opening and which opposes the first region of the first disk-shaped joining part. The elevation interacts with the depression in sealing fashion.
