Abstract: 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.

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.

Abstract: An additive manufacturing system for producing a structure includes a base assembly, an elongated member, a carriage, and a first member. The elongated member is fixedly coupled with the base assembly and extends upwards from the base assembly. The carriage is rotatably coupled with the elongated member and configured to translate upwards along the elongated member. The first member is fixedly coupled with and extends outwards from the carriage. The first member includes a material dispensing device configured to dispense material as the carriage rotates relative to the elongated member.

Abstract: A damper assembly includes a tubular member including a sidewall and a shoulder. The damper assembly includes a rod and a piston coupled to the rod. A secondary piston has a second contact surface, an opposing second surface, an inner cylindrical face defining a central aperture that receives the rod, and an outer cylindrical face. The opposing second surface includes one or more surface grooves, extending between the inner cylindrical face and the outer cylindrical face along the opposing second surface, and one or more bypass orifices disposed about the body member. The bypass orifices extend along the inner cylindrical face between the second contact surface and the opposing second surface. The secondary piston defines a channel extending between the inner cylindrical face and an outer periphery of the body member. The channel and bypass orifices form a fluid flow path when the piston contacts the secondary piston.

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.

Abstract: A printhead for an additive manufacturing system includes a hopper, an outlet, a mixing shaft, and a drive shaft. The hopper includes an inner volume configured to store a slurry material for mixing. The outlet includes a passageway fluidly coupled with the hopper. The outlet includes an open end for discharging the slurry material to a surface through the passageway. The mixing shaft extends through the inner volume of the hopper and includes a member that extends radially outwards from the mixing shaft. The member is configured to mix the slurry material within the hopper as the mixing shaft rotates. The drive shaft extends through the inner volume of the hopper and at least partially into the passageway of the outlet. The drive shaft includes a sloped surface configured to drive the slurry material from the hopper to the surface through the passageway of the outlet.
