KOLBENDÄMPFUNGSANORDNUNG UND STAUBROHRUNTERANORDNUNG MIT GESCHWINDIGKEITSSENSOR

摘要

A piston damper assembly (10) includes a piston damper (12) and a relative position sensor (14). The piston damper includes a damper body (16) and a piston rod (18). The piston rod is axially movable within the damper body. The relative position sensor includes an axially-extending magnetic core (20), an excitation coil (22), and a position-sensing coil (24). The axially-extending magnetic core is movable with the piston rod, is located outside the damper body, and has first and second protrusions (26 and 28) extending toward the damper body. The excitation coil is wound around the first protrusion (26), and the position-sensing coil is wound around the second protrusion (28). A piston-damper dust tube subassembly (48) includes an axially-extending piston-damper dust tube (38) and a relative position sensor (14). The relative position sensor includes an axially-extending magnetic core (20), an excitation coil (22), and a position-sensing coil (24). The axially-extending magnetic core is attached to the dust tube and has first and second protrusions (26 and 28).
