Pressurized telescopic front fork leg, front fork and vehicle
A front fork for a vehicle comprises a telescopic fork leg having an outer tube and an inner tube telescopically arranged relative each other. A main piston arrangement in the inner tube regulates a damping fluid for damping movements between two parts of the vehicle. The telescopic fork leg comprises a pressurizing piston arranged in the inner tube and configured to pressurize the damping fluid. The pressurizing piston comprises an axial first end portion facing the main piston arrangement an axial opposite second end portion facing a pressurized volume. A fluid reservoir for holding a pressurized fluid is fluidly coupled to the pressurized volume. The pressurizing piston is coaxially arranged with the main piston arrangement, inside the inner tube. The fluid reservoir is at least partly arranged on an outside of the inner tube. Also, a front fork and a vehicle having fork legs according to above are described.
GAS CUP FOR A DAMPER ASSEMBLY AND A DAMPER ASSEMBLY
A gas cup for a damper assembly comprises a body including an upper surface, a lower surface, an exterior surface and an interior surface. The body defines an aperture extending through the upper surface and the lower surface. A decoupler is located in the aperture and secured to the body. A bridging member is located between the decoupler and the body and coupled to the decoupler and the body. The decoupler and the bridging member is made from materials having different elasticity to allow the decoupler to move in the aperture in response to a volumetric change in the damper assembly and to provide variable tuning of the damper assembly. A damper assembly including the gas cup is also disclosed herein.
Suspension element
A suspension element includes a main body having an internal volume, a tubular element extending at least partially within the main body, the main body and the tubular element each including a sidewall having an inner surface and an outer surface, a first piston assembly separating the internal volume of the main body into a first chamber and a second chamber, the second chamber defined by the outer surface of the tubular element, the inner surface of the main body, and a surface of the first piston assembly, and a second piston assembly including a side that is directly exposed to the first chamber. The sidewall of the main body defines an aperture therethrough that forms a portion of a flow path between the first chamber and the second chamber. The first piston assembly is configured to prevent direct fluid communication between the first chamber and the second chamber.
DEVICE FOR VOLUME COMPENSATION OF THE DAMPING LIQUID FOR A DAMPER
A device for volume compensation of damping liquid for a damper includes a hollow cylindrical main body containing the damping fluid. A rod extends through an end of the main body to the interior thereof. The rod is secured to a piston inside the body, which divides a compression chamber from an expansion chamber. A compensation chamber is connected to the compression and expansion chambers via internal channels of the rod and piston. A plurality of orifices in the piston open into the compression chamber and into the expansion chamber. A rigid slider moves freely in translation through, around or inside the piston and/or the rod and closes and opens the orifices to connect the compensation chamber to the expansion chamber (or, respectively, the compression chamber) in the compression (or, respectively, expansion) phases. The device may be used in vehicle wheel suspension assemblies.
Protective cover for electrical coupler of vehicle shock absorber and vehicle shock absorber including same
A shock absorber for damping movement of a wheel suspension system of a vehicle can include a damper tube, a piston, a damping adjustment assembly, and a protective cover. The damper tube can contain a fluid. The piston can be located in the damper tube so as to accommodate relative movement between the damper tube and the piston. The damping adjustment assembly can be connected to the damper tube, and can include a reservoir, a solenoid valve, and a wire harness connection. The solenoid valve can be in fluid communication with each of the reservoir and the damper tube and configured to selectively open and close fluid communication between the reservoir and the damper tube. The wire harness connection can be in electrical communication with the solenoid valve. The protective cover can contain the wire harness connection.
Suspension element lockout
A suspension element includes a main body having an end cap defining an internal volume and a tubular element slidably engaged with the main body. The suspension element further includes a first piston and a flow control element. The flow control element is configured to prevent movement of the tubular element relative the main body in a direction. The suspension element may further include a locking member and a piston. The locking member may be configured to engage a barrier of the main body when the first piston traverses at least a predetermined distance towards the end cap. The locking member may be affixed to the tubular element and may fully surround the tubular element. Together the flow control element and the locking member are configured to prevent movement of the suspension element.
Shock absorber
A shock absorber including: a first cylinder having an interior, first and second ends and defining an axis, wherein the interior includes a damping fluid chamber and a damping piston movably mounted therein for movement between the first and second ends, wherein the damping piston is mounted on a first end of a shaft, wherein the first end of the shaft is movably retained within the interior of the first cylinder; first and second bypass openings configured for opening into the damping fluid chamber at first and second axially spaced-apart positions; a bypass channel fluidly coupling the first and second bypass openings; a fluid metering valve; and a floating piston dividing a portion of the shock absorber into a gas chamber and the reservoir chamber, wherein the fluid metering valve and the floating piston define the reservoir chamber there between.
Vibration damper and vehicle
A vibration damper may include an external tube and at least one internal tube. The external and internal tubes may be disposed in a coaxial manner relative to one another. An annular gap may exist between the external tube and the internal tube, and the annular gap may be fluidically connected to the internal tube. The annular gap may form a compensation chamber for receiving damper oil and damper gas for preloading of the damper oil in the compensation chamber. The vibration damper may further include a separating element disposed in the compensation chamber. The separating element may be axially displaceable and may separate the damper oil from the damper gas in a fluid-tight manner.
Multi-stage shock absorber and method for using the same
A shock absorber having a plurality of pistons in a telescopic or nested configuration. The shock absorber has a first shaft with a first piston disposed within a cylinder filled with a hydraulic fluid. A second shaft is in turn disposed within the first shaft, the second shaft having a second piston extending beyond the position of the first piston. The second shaft is further coupled to a vehicle's suspension system. When undergoing a displacement, the second piston moves through the cylinder and compresses an external spring. After the second shaft has been fully extended, the first piston is then actuated, thereby also moving through the hydraulic fluid. As the pistons traverse through the cylinder, a volume of the fluid is pushed into a reservoir communicated to the cylinder. Both the first and second shafts are configured to move independently with respect to each other and to the cylinder.
Vehicle Shock Absorber
A vehicle shock absorber has a body extending between a first end and a second end. Translation of a primary shaft within an interior cavity of the body communicates a first volume of fluid within the interior cavity to a secondary reservoir where it increases pressure in a gas cavity therein. The primary shaft has an annular member engaged thereon which contacts a bump shaft slidably located in an opening at the first end of the body. The contact of the annular member translates the bump shaft within the interior cavity to cause communication of a secondary volume of the fluid to the secondary reservoir.
