Abstract


This paper presents elements of the kinematic and dynamic study of the mechanical transmission within the structure of a vehicle designed to serve persons with locomotor disabilities. The mechanical transmission consists of two kinematic chains, one for straight-line movement and the other for turning. We have two differential groups with conical gears that allow for easy maneuvering in crowded spaces. For straight-line movement, cylindrical gears are used. The first part of the paper studies the kinematics and dynamics of the vehicle's motion, identifying the time-varying diagrams of kinematic and dynamic parameters. The second part conducts a dynamic analysis using the finite element method of a cylindrical gear, particularly focusing on the development and analysis of dynamic contact models.
