Cabin Bike Landing Gear

Second Generation

The landing gear on our enclosed motorcycle is a rolling kick stand of sorts and is intended to be deployed at low speeds or at a stop on smooth terrain when the vehicle is level (zero degree roll). The gear is manually operated by the driver by means of a switch located on the left side of the handle bars which operates relays that power air valves (solenoids).  Position displays on the dash controlled by magnet reed switches mounted on the gear indicate whether the gear is up or down.

The second generation landing gear is pneumatic.  The system consists of 2 pneumatic cylinders (a.k.a air rams), an on-board compressor, air holding tank, a bank of 4 solenoids, and two relays. The solenoids are wired in pairs and in such a way that they draw no power unless the landing gear is actually in motion. The first pair pushes air into one end of the rams while allowing air out of the opposite ends. The second pair operates similarly, however, in the opposite direction. When the gear is not in motion, all valves are closed. See schematic below.

All of the CAD drawings (patterns) depicted below are available to members in Auto CAD .dxf format for plasma or laser cutting.

Magnetic reed switches located on the rear of the firewall are activated by a magnet located on one of the gear arms and are wired to position indicators on the dash.
