In this paper is presented the development of a wheelchair intended to be use by the people with locomotors disabilities. They are presented various solutions of kinematics schemes proposed to be implemented as a mechanical transmission for the wheelchair. The developed wheelchair integrates a mechanical transmission which allows the movement in a straight line, and also in cornering. The mechanical transmission implemented contains a bevel gearbox. The purpose of the bevel gearbox is to multiply the moment transmitted to the motor wheels for movement on uneven terrain. They are presented aspects concerning the design of the wheelchair frame an of implemented bevel gearboxes.
