Abstract

This bachelor thesis deals with the structural design of the frame and drivetrain of family pedal quadricycle. Begin of thesis includes comparison of quadricycles types. Thereafter is defined power of untrained man and designed optimum position of sitting. Based a comparison of quadricycles types is designed drivetrain. For designed drivetrain are selected components and is done construction design of shaft and check for torsion. Is contained construction design of frame and its strenght check. Thereafter are done calculations of the acting forces and is calculated a durability of designed bearings. Thesis contains calculations of gear ratios on the base of selected components of the drivertrain. The thesis also includes kinematic calculations for finding the maximum gradeability and maximum speed on plane.
