    • A ball ramp actuator having first and second actuation plates with a control plate disposed therebetween where a plurality of circumferential variable depth grooves are formed in a first face of the first actuation plate and in first and second faces of the control plate where the grooves formed in the first face of the control plate are directly opposed to the grooves formed in the second face of the control plate where the actuation grooves and the control grooves form opposed pairs of grooves having a rolling member disposed within each pair of grooves for axially separating the first and second actuation plates from the control plate as the rolling members traverse their respective grooves such that the rolling members contacting the first face of the control plate directly oppose the rolling elements contacting the second face of the control plate to provide a balanced axial force on the control plate.
    • 一种具有第一和第二致动板的滚珠坡道致动器,其中设置有控制板,其中多个圆周可变深度槽形成在第一驱动板的第一面中,并且在控制板的第一和第二面中形成有槽 控制板的第一面与控制板的第二面中形成的槽直接相对,其中致动槽和控制槽形成相对的一对槽,该对沟槽具有设置在每对槽内的滚动件,用于将第一 以及随着滚动体横过其各自的槽而从控制板的第二致动板,使得接触控制板的第一面的滚动件直接与接触控制板的第二面的滚动元件相对,以在 控制板。
