A roller guide wheel contains a single set of spherical bearings and is constructed with a precision outer race machined into the guide wheel interior and an inner race formed by the surfaces of two conically-tapered set screws that affix the roller guide wheel within a housing made part of a stage slider. The roller guide wheel, which contacts a rail on one side of the stage body and exhibits a non-nutating axis of rotation, serves as way for the translating slider. The way on the opposing side of the slider is a set of v-groove contacts that make sliding contact with a rail on the corresponding side of the stage body. A flexure is machined into the slider permitting preload of the slider contacts points with the rails. The stage geometry permits a large slider through-hole and the use of alternative way mechanisms with the roller guide wheel.

A ballscrew actuator comprises a ballnut having at least one first helical groove formed on a radially inner surface and defining an axis (X), a ballscrew disposed along the axis (X) within the ballnut, the ballscrew having at least one second helical groove formed on a radially outer surface and opposed to the first helical groove so as to form at least one helical raceway and a plurality of balls or rolling elements disposed in the at least one helical raceway. The ballscrew is movable relative to the ballnut between a stowed position and a deployed position. The ballscrew comprises a ballscrew bore extending axially therein. A lubrication piston is mounted for sliding movement within the ballscrew bore and divides the ballscrew bore axially into a lubricant receiving portion and a pressurising portion.

A hybrid drivetrain for a hybrid-drive vehicle, including an electric motor and an internal combustion engine, the force output shaft of which alternatingly acts either on a first input shaft or on a coaxial second input shaft of a dual clutch transmission via two separating clutches of a dual clutch, wherein a respective first and second sub-transmission can be activated using the input shafts, and wherein fixed and idler gears are arranged in wheel planes on the two input shafts and a common axially parallel output shaft and are combined into gear sets which form gear stages.

The invention relates to an actuator (1) comprising: a body (4), a first element (5) mounted such that it can move rotatably in relation to said body (4), and a second element (6) mounted such that it can move translatably in relation to said body (4), either the first element (5) or the second element (6) being a screw and the other one being a nut, the nut cooperating with the screw such that a rotation of the first element (5) in relation to the body (4) around an axis of rotation (X) causes the translation of the second element (6) in relation to the body (4) parallel to the axis of rotation (X), a cylinder which is stationary in relation to the first element (5), a piston mounted such that it can move translatably inside the cylinder between a first end position and a second end position, and a cam surface which is stationary in relation to the body (4) and against which the piston is supported such that a rotation of the first element (5) in relation to the body (4) causes a translatory back-and-forth movement of the piston between the first end position and the second end position.

A torque load binder for changing tension in a chain or strap securing a load to a vehicle or support surface. The load binder includes a housing with an internal gear mechanism and a connector mechanism operatively engaged with the gear mechanism and extending outwardly from the housing. A high speed first driveshaft and a lower speed second driveshaft on the load binder are selectively individually actuated to effect movement between first and second end linkages of the connector mechanism. The first driveshaft effects movement between the first and second end linkages at a first speed and the second driveshaft effects movement between the end linkages at a lower second speed. Rotation of either of the first or second driveshafts actuates the connector mechanism, changing the distance between the first and second end linkages, and thereby changing the tension in the tie-down.
