The work presents the aproach of the finite element investigation of the cardan transmission joint. We treat the problem of structural behaviour, such as analyses that target the strength-related behaviour. It is thus sought to determine certain parameters (nodal displacements, stresses, strains) in the conditions of applying various types of loads - forces, pressures or moments. For this, we used a software for finite element analysis – Cosmos - a product integrated in the Solidworks package. We insisted on calculation of the cardan transmission for Dacia 1307 but they can be easily transposed also to other typodimensions of cars, machines or medical devices from the same category.
