The paper deals with a windshield wiper mechanism with two parallel rocker blades having a complex topological structure. In the first part of the paper, the mobility of the mechanism is analyzed by means of the simplest formula for planar linkages. Also, the topological structure consisting of adyad and a tetrad has been outlined. In the second part of the paper, a kinema-tic analysis of the multi-contour mechanism is performed, the angular displacements of the two rocker blades being obtained. In this regard the independent contour method has been used, the angular displacements of all kinematicelements of the mechanism being calculated. Moreover, the displacement systems have been derived in order to obtain the velocities and late-on the accelerations of the mechanism elements. Finally, the paper ends with the displaying of the kinematic charts of the mechanism elements of which those with themovement of the two parallel rocker blades are the most wanted. This is due to the requirement of maximization of the wiping surface which is a very important safety issue.

Cycloid reducers compared with classical reducers have low axial and radial gauge, high transmission ratio, and a better reliability. Cycloid gearing roller, through its qualities, has an important role in modern mechanical transmissions. The difference between numbers of teeth of the cycloid gear roller can be equal to 1 (|z1 -z2| ≥ 1), without risk of interference, as a result, can be obtained big gear ratios in accordance with in lower overall dimensions, while the classic gear have the difference between teeth number min | z1 -z2 | ≥ 4. In this paper, the physical prototype of a new version of roller cycloid reducer is presented. Also one tries to test this variant of cycloid gear on a modern stand trial.

“…Curve line translation motion, in particular circular translation, can be generated by means of planar mechanisms with articulated links [1,3,4,7] such as the articulated parallelogram (fig. 1), or by means of planar mechanisms with cylindrical gears [1,2,3,5,6,8,9] such as the Fergusson mechanism (fig. 2).…”

The curve line translation motion can be generated in the particular form of the circular translation, through mono-mobile mechanisms with articulated links of simple parallelogram type (with a fixed side) or through transmission with toothed belt with a fixed wheel. Also, the circular translation can be generated through planar mechanisms with two cylindrical gears with a fixed central wheel. It is mentioned that the two cylindrical gearings of the Fergusson mechanisms are both exterior and interior.
