Abstract: A rotary damper for remote-controlled vehicles is described. The rotary damper includes a housing containing a fluid, a rotary joint, a rotating member, a protrusion extending from the first end of the rotating member dividing a space within the housing into at least two portions, and a rocker arm. In operation, a linear motion applied to the rocker arm translates into rotary motion on the rotating member, causing the protrusion to move through the fluid within the housing. An elastic member may be coaxially mounted on the rotating member to resist the rotary motion translated from the rocker arm. The elastic member generates a spring force, and the protrusion moving through the liquid generates a damping force. In other examples, the damping force is generated using a fluid-shearing object moving through the liquid, such as a slotted disc or an impeller.
