摘要

The spindle has a spindle unit (21) with a rolling groove (211), and a ball nut (22) with a through hole (221). A rolling groove (222) is formed at a limiting wall of the hole and forms a load path (26). A circulating element is designed as an orbit and is arranged at an outer side of the nut. Roll elements (25) roll inside the load path and the orbit in a circulate manner. A noise suppression cap (30) is attached to the outer side of the nut and includes a noise suppression channel, whose both ends are arranged at a joint, in which the roll elements are pushed against the rotating element.
