摘要： An apparatus for use in turning steerable vehicle wheels includes a rotatable shaft that is rotatable relative to the vehicle to effect turning movement of the steerable vehicle wheels. A ball nut assembly is connected with an externally threaded portion of the rotatable shaft. The ball nut assembly moves axially relative to the rotatable shaft upon rotation of the rotatable shaft relative to the ball nut assembly. A steering member is connected to the ball nut assembly and at least one steerable vehicle wheel. The steering member moves with the ball nut assembly relative to the shaft. An electrical motor is connected with the rotatable shaft. The motor is operable to effect rotation of the rotatable shaft relative to the ball nut assembly to turn the steerable vehicle wheels.

摘要： A linear motion device includes: a bearing mounted to the outer periphery of a ball screw; a nut holder through which the ball screw passes; and a bearing pressing member which is fixed to a motor housing with the ball screw inserted in a through hole and which restricts the movement of the bearing in the motor housing in the axial direction. The bearing pressing member has a cutout portion extending from the inner peripheral surface of the through hole over to the outer peripheral surface of the bearing pressing member in the radial direction.

摘要： A motion control system includes a top mount, a bottom mount, a rigid housing, an air spring, and a linear actuator. The air spring transfers force of a first load path between the top mount and the bottom mount. The air spring includes a pressurized cavity containing pressurized gas that transfers the force of the first load path. The linear actuator transfers force of a second load path between the top mount and the bottom mount in parallel to the first load path. The rigid housing defines at least part of the pressurized cavity and transfers the force of the second load path.

摘要： Some embodiments relate to an electro-mechanical actuator that includes a screw, structurally segregated (split) housings, first and second nuts coupled to the screw, a sensor assembly, a plurality of motors, and a controller. The first nut is coupled to a first mounting point, and the second nut is coupled to a second mounting point. The sensor assembly may generate signals indicative of (e.g., relative) positions of left and right units of the actuator or positions of the first nut and the second nut on the screw. The controller controls the motors based on the signals generated by the sensor assembly. The motors may rotate each nut about a screw axis of the screw. This rotation results in one or both nuts moving along the screw. Movement between the first nut and the second nut along the screw adjusts a distance between the first mounting point and the second mounting point.

摘要： An electromechanical actuator may include a motor assembly and a ball nut. A split ball screw may be disposed between the motor assembly and the ball nut. The split ball screw may have an inner portion and an outer portion. The inner portion may interface with the motor assembly. The outer portion may interface with the ball nut. A pin may be configured to engage with the inner portion and the outer portion of the split ball screw to couple the outer portion with the inner portion.
