    摘要： An actuator comprises a rotatable nut arranged to be driven for rotation by a motor, an axially translatable shaft cooperable with the nut and arranged such that rotation of the nut drives the shaft for axial movement, and a steering rack coupled to the shaft by a coupling arrangement so as to be driven for axial movement by the shaft, wherein the coupling accommodates limited relative lateral movement between the shaft and the steering rack.

    摘要： A ball screw which has a threaded nut arranged on a threaded spindle, a helical ball channel in which balls are arranged delimited by ball grooves of the threaded spindle and the threaded nut, a ball cage which receives the balls and a spring element which bears with one end against the threaded nut and with another end against the ball cage. The spring element is arranged axially adjacent to the ball cage in an annular gap delimited by the threaded nut and the threaded spindle.

    摘要： The invention relates to a telescopic actuator comprising: a cylinder having means for coupling it to a first external element; a rod mounted to slide telescopically in the cylinder along a sliding axis and including means for coupling it to a second external element; a lead screw mounted to rotate in the cylinder about the sliding axis and extending inside the rod to co-operate with a nut secured to the rod, such that rotating the lead screw causes the rod to slide; drive means for driving the lead screw in rotation; and retention means for axially retaining the lead screw, which means hold a bearing of the lead screw captive in an axial direction; wherein the retention means are arranged to retain the bearing of the lead screw with axial clearance suitable for absorbing movements imparted to the rod relative to the cylinder.
