Abstract

Viene proposto un cuscinetto compatto (14), il quale possiede un unico anello di supporto (15) per un cuscinetto a rotolamento interno cuscinetto ad aghi (15, 17, 18) e per un cuscinetto esterno a quattro punti (15, 21, 26, 27).In tal modo si è realizzato un cuscinetto doppio poco ingombrante ed economico. Il cuscinetto compatto è destinato all'impiego in servosterzi, laddove il cuscinetto a quattro punti (15, 21, 26, 27) può essere arrestato rotoriamente od attivato a seconda se la sterzatura viene effettuata con oppure senza servosterzo.A compact bearing (14) is proposed, which has a single support ring (15) for an internal rolling bearing needle bearing (15, 17, 18) and for an external four-point bearing (15, 21, 26 , 27) .In this way a space-saving and inexpensive double bearing was created. The compact bearing is intended for use in power steering, where the four-point bearing (15, 21, 26, 27) can be stopped rotorically or activated depending on whether the steering is carried out with or without power steering.
