| Summary: | In this paper are presented the authors contributions on designing and evaluation of a
mechanical transmission intended to be used to wheelchairs for disabled people. In most cases the
wheelchairs propulsion system solution consist of two DC motors, mounted on wheels shafts
directly, or by means an intermediary transmission with chains or belts. In this case the
wheelchair must be equipped with a controller, generally based on a PWM technology. Proposed
solution consists of a mechanical transmission based on differential gears, which uses two motors,
for steering and for propulsion. For this design architecture the control solution is much simple
and easy cost to design, consisting in one servo controller for two motors. Based on dimensional
synthesis of transmission gears, is developed the design solution of the robotic wheelchair. The
wheelchair motion simulation is studied in Adams software, for the case of traction, steering and
combined motion. From Adams simulations are obtained the wheelchair motion trajectories,
kinematic and dynamic parameters. Obtained results are analyzed and compared to other
wheelchairs design solution, concluding that proposed design solution of this transmission can be
successful used to a wheelchair experimental prototype. |
