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: 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.

Abstract: Systems and methods for controlling one or more tractive assemblies of a vehicle responsive to a disabling event. A sensor is arranged to detect one or more conditions of a tractive element indicative of the functionality of the tractive element. The sensor generates data corresponding to the detected conditions. The tractive element is coupled to a frame of the vehicle and configured to support a portion of the weight of the vehicle. When the tractive element is determined to not be functioning properly, control signal(s) for an actuator are generated to control a distance between the tractive element and the frame. The control signal(s) cause the tractive element to be effectively raised from a support surface for the vehicle.
