Abstract
The invention is directed to a swashplate angle sensor (10) for a variable displacement hydraulic unit (1). The hydraulic unit (1) comprising a housing (2), within which a swashplate (3) with a rod shaped feedback-link (12) fixedly attached to the swashplate (3) is arranged pivotable around a swashplate axis (7). The angle sensor (10) comprising a magnet (16) mounted rotatable on a magnet carrier (13), and a sensor (15) for sensing the orientation of the magnet (16). The magnet carrier (13) is located in a control block (14) attached to the housing (2) and is located parallel to the feedback-link (12). The magnet carrier (13) is rotatable around a sensor axis (18) being parallel to the swashplate axis (7). A linkage spring (11) provides a connection between the feedback-link (12) and the magnet carrier (13) such that a pivoting of the swashplate (3) with the feedback-link (12) causes a rotation of the magnet carrier (13).
