摘要:
A divided roll stabilizer of a motor vehicle between whose two stabilizer parts (2a) an actuator (1) can be arranged for a torsion of the stabilizer parts (2a). At least one of the stabilizer parts (2a) is provided with a torsion transmitting connecting part (4a) for connection to the actuator (1), and the connecting part (4a) is magnetically coded.
摘要:
An electromechanical actuator, especially for an anti-roll bar of a motor vehicle, that has two actuator elements, which can be rotated relative to each other about a common rotational axis, for which purpose an electric motor and a gearbox coupled therewith are provided. The electric motor is arranged in an actuator element for transmitting a torque, and an output shaft of the gearbox is coupled to the other actuator element. A mechanical overload coupling is provided in the torque-transmitting load path from the electric motor to the gearbox output shaft.
摘要:
A suspension actuator (1) for positioning a movably mounted component of a motor vehicle suspension, including a first actuator component (4), which is to be connected to the movably mounted component, and a second actuator component (3), which is to be connected to a fixed suspension component, wherein both actuator components can be axially adjusted relative to one another via a ball-type linear drive (5), which includes a threaded spindle (6) and a nut (7) running thereon. Either the nut can be driven via a drive motor (10) for the axial adjustment of the threaded spindle or the spindle can be driven via a drive motor for axial adjustment of the nut. A brake unit (14, 28), which can be actuated by an external force on the suspension side and acts on the nut (7) or the spindle and rotates them, and which builds up a friction torque opposing a nut rotation or the spindle rotation, which acts between the nut (7) or the spindle (6) and a fixed actuator element (22, 35) or between a drive shaft of the drive motor (10) and a fixed actuator element (45) associated therewith, is provided.

摘要:
The present invention refers to a catalyst for the manufacture of methyl mercaptan from carbon oxides comprising Mo and K compounds and oxides or sulfides of metals chosen from the manganese group. The improvement of the present process consists of the fact that carbon dioxide can be converted with higher conversions and selectivities to methyl mercaptan as compared to state-of-the-art technologies, with only minor amounts of carbon monoxide being formed as side product. Simultaneously, carbon monoxide can be easily converted into carbon dioxide and hydrogen by reaction with water using established water-gas-shift-technologies thus increasing the overall selectivity to methyl mercaptan.
摘要:
The ball screw mechanism has spindle nut (1) arranged rotatably on a ball-rolling spindle (2) and between which balls (3) roll on ball grooves (4, 5). A driving wheel (20, 26) is fixed to the spindle nut (1), for driving the spindle nut. (1)The spindle nut (1) is mounted on a housing (8) by a rolling bearing (7). The bearing has an outer ring (9, 23) fixed to the housing (8) the outer ring (9, 23) has a ring (15, 29) surrounding the spindle nut (1), and a bearing running surface (10, 11) formed on the inner circumference of said the ring A radial flange (16, 28), adjoining the ring (15, 29), is fixed to the housing (8).
