摘要： A steering gear for a steer-by-wire steering system of a motor vehicle may include a hollow shaft motor with a stator that is fixed to a housing and a rotatably supported rotor that is arranged coaxially with respect to a longitudinal axis. A worm gear may extend through the rotatably supported rotor. The worm gear comprises a spindle nut that is arranged coaxially relative to the longitudinal axis, that is connected in terms of driving to the rotor, and that is located on a spindle that is displaceable by way of the hollow shaft motor along the longitudinal axis. The angle of inclination of the worm gear may be less than 4.5°.

摘要： A fluid-bed granulator system for producing fertilizer granules with a defined size including a fluid-bed granulator, a first cooler externally connected with the fluid-bed granulator or forming an internal part of the fluid-bed granulator, and a product screen connected with the first cooler. The product screen includes an exit for on-size particles; an exit for oversized particles and an exit for undersized particles. The exit for undersized particles is connected to the fluid-bed granulator and the exit for oversized particles is connected to the fluid-bed granulator via one or more crushers. The exit for on-size particles is connected to a first splitter. The first splitter is connected to the fluid-bed granulator and a post processing unit. A particle size analyzer is located between the fluid-bed granulator and the product screen.

摘要： A vibration damper for a vehicle includes a damper tube, a working piston and a rebound stop arrangement. The damper tube is filled with hydraulic fluid. The working piston is connected to a piston rod and is arranged such that it can be moved within the damper tube. An interior space of the damper tube is divided by way of the working piston into a first working space and a second working space. The rebound stop arrangement includes an additional piston (30) which is attached to the piston rod and encloses the piston rod concentrically. A sleeve-shaped rebound stop receptacle is attached to the damper tube for receiving the additional piston in the rebound stage. The rebound stop arrangement has a spring element which is arranged at least partially within the rebound stop receptacle. The spring element is fastened to the additional piston.

摘要： A rotor and a method of making such a rotor, wherein the rotor has a shaft, a longitudinal axis, and a rotor packet connected to the shaft at least in torsion-resistant manner. The rotor packet is assembled from individual sheet lamellae, wherein the rotor packet has an opening for receiving the shaft. The shaft is a hollow shaft with a wall, wherein the wall of the shaft has, on its side facing toward the opening, recesses extending in the longitudinal direction. An electric motor, in particular a synchronous or hybrid synchronous machine, including a rotor and a stator, has such a rotor. The recesses are produced by cutting methods, in particular milling, or reshaping methods, in particular pressing.

摘要： A steering gear for a steer-by-wire steering system of a motor vehicle may include an electric motor having a motor shaft. The motor shaft drives a spindle of a worm gear, and the worm gear comprises a spindle nut in such a manner that a rotational movement originating from the motor shaft is converted into a linear movement of the spindle nut along an axis. The spindle nut, for purposes of steering wheels of the motor vehicle, is connected to at least one tie rod. The worm gear may be a ball screw drive, a trapezoidal drive, or a roller screw drive.

摘要： A steering gear for a steer-by-wire steering system of a motor vehicle may include a coupling rod which is supported in a steering gear housing and on which a threaded spindle is formed, with the threaded spindle being surrounded by a spindle nut. The threaded spindle and the spindle nut may be part of a helical gearing, and the coupling rod is movable along a longitudinal axis by way of the helical gearing. The coupling rod is movably mounted in the steering gear housing along the longitudinal axis by way of a pressure piece having two bearing elements arranged on opposite sides of the coupling rod in a circumferential direction of the longitudinal axis.

摘要： A steering column for a motor vehicle may include an inner casing in which a steering spindle is mounted rotatably about a longitudinal axis that extends in a longitudinal direction and is received in an outer casing in a slidingly adjustable manner in the longitudinal direction. A pretensioning apparatus may have a pressure piece that can be braced from an outside in a tensioning direction transversely to the longitudinal axis against the inner casing. The pressure piece is held in the longitudinal direction on the outer casing and is supported against a fixing element counter to the tensioning direction. The fixing element is fixed in a recess of the outer casing. The fixing element has a forming means that is plastically furrowed into the recess, and/or the recess has a forming means that is plastically furrowed into the fixing element.
