Wiper arm linkage system

摘要

The system has a case for enclosing a gear linkage system, and a beam (11) formed by two half-beams (11a, 11b) engaged with a shaft (3). A connecting rod (15) is articulated with an axle (13) at an end of the beam. The beam comprises a spacer (17) placed between the half-beams, where distance between the half-beams in a support against the spacer corresponds to thickness of the gear linkage system around the shaft, so that the case forms a sliding bearing for the half-beams around the shaft, by sliding contact. The spacer comprises a ring such as metal ring and plastic ring. An independent claim is also included for a windscreen wiper system for a car.
