Abstract
A ball nut assembly comprises a spindle having a longitudinal axis, a ball nut, and bearing elements supporting the ball nut on the spindle. First, second, third, and fourth ball nut deflectors are between the ball nut and the spindle. First, second, and third planes extend parallel to the axis. The first and fourth ball nut deflectors are in the first plane, the second ball nut deflector is in the second plane, the third ball nut deflector is in the third plane. Furthermore, the second and third ball nut deflectors are on opposite sides of the first plane. A first acute angle is between the first and second planes and a second acute angle is between the first and third planes.
