Wiper washer

The windshield wipers of the buses must sweep an area much larger than that of the cars, it is convenient that the brush is always kept in an upright position so that the water from the windows is fired. If you activate the Trail, the areas that sweep the brushes are represented. This is achieved with the articulated parallelogram on the right, if OO 'is fixed and horizontal to the ground, PQ will also be fixed and we articulate the brush so that it is perpendicular to the ground.
