  • SUSPENSION ELEMENT SYSTEMS AND METHODS
    Publication number: 20210155063
    Abstract: A vehicle includes a support arm and a suspension element. The suspension element is rotatably connected to a support arm of a vehicle via a mounting pin that extends through an opening on the suspension element, a thrust washer, and a seal. The combination of elements prevent debris from migrating into the connection. The suspension element is configured to connect to a structural element of the vehicle via an upper mount. The suspension element may include a recoil damper having a piston with a plurality of grooves arranged to balance the forces on the piston during and after a recoil event or jounce.

  • Suspension element
    Patent number: 10974561
    Abstract: A suspension element includes a main body having an internal volume configured to contain a liquid therein, a tubular element extending at least partially within the main body, the tubular element having an internal volume that defines a first fluid chamber configured to contain a compressible gas therein, a first piston separating the internal volume of the main body into a second fluid chamber and a third fluid chamber, a second piston positioned to separate the first fluid chamber from the second fluid chamber, and a flow control element disposed along a flow path between the second fluid chamber and the third fluid chamber. Movement of the tubular element generates a flow of the liquid through the flow control element to produce a damping force and changes the pressure of the compressible gas to produce a spring force.
