摘要:
Method and compressor arrangement for generating compressed air, particularly for commercial vehicles, which is generated by way of a compressor unit (3) driven by an internal-combustion engine (1) from the ambient air according to a control unit (14), in which cases, by means of the compressor unit (3) operated by the internal-combustion engine, compressed of only a low pressure level is generated for assigned low-pressure consuming devices (7a, 7b), and in that, starting from the compressed air of the low pressure level, by means of a separate auxiliary compressor unit (8), compressed air of a high pressure level is generated for assigned high-pressure consuming devices (11a, 11b), the coordinated triggering of the two compressor units (3,8) being carried out, in a pressure-demand-controlled manner, centrally by means of the control unit (14).
摘要:
Air-demand-controlled compressor arrangement, particularly for commercial vehicles, includes a motor unit for generating a rotating movement which, by way of an interposed rotational-speed-transmitting transmission unit, drives a compressor unit for generating compressed air from ambient air. A control unit triggers the generating of compressed air in the case of a compressed-air demand. The transmission unit is constructed in the manner of a transmission whose rotational speed can be varied, and the control unit interacts with the transmission unit in order to adapt the rotational speed of the transmission unit corresponding to the compressed-air demand.
摘要:
An internal-combustion engine for generating a rotational movement is provided to drive a compressor unit which is connected on the output side, for generating compressed air from ambient air. A control unit triggers the generating of compressed air when compressed air is demanded. An auxiliary compressor unit covers peak demands for compressed air and is fluidically connected in parallel with respect to the internal-combustion-engine-driven compressor unit. The auxiliary compressor unit is driven by an electric motor. The control unit starts the operation of the auxiliary compressor unit in the event of a detected peak demand.

An adjusting device for a transmission is described. The device has at least one movable adjusting element, a plurality of sensors for detecting a position of the at least one movable adjusting element, which are arranged substantially parallel to one another, and a plurality of cam paths having sections of different heights, assigned to corresponding ones of the plurality of sensors. The device also includes a plurality of scanning elements coupled to the plurality of sensors for mechanically scanning the sections of different height, and at least one catch of each of the plurality of cam paths in which a latching element is engageable, wherein the plurality of sensors and the latching element are designed as a common component. The plurality of cam paths result in comparable stroke movements arising for each of the plurality of scanning elements.

A sintered nuclear fuel body includes (U, Pu)O2 mixed crystals having a mean particle size in a range from 7.5 &mgr;m to 50 &mgr;m. This sintered nuclear fuel body has a high retention capacity for fission gas in a power reactor. In order to produce the sintered nuclear fuel body by sintering a body in a hydrogen-containing sintering atmosphere, a powered substance selected from the group consisting of aluminum oxide, titanium oxide, niobium oxide, chromium oxide, aluminum stearate, aluminum distearate and aluminum tristearate is added to the starting powder for the body. As an alternative or in addition, the body made from the starting powder is sintered during a holding period of 10 minutes to 8 hours at a sintering temperature of 1400° C. to 1800° C. in a hydrogen-containing sintering atmosphere, initially with an oxygen partial pressure of 10−10 to 10−20 bar and then from 10−8 to 10−10 and then cooled in a hydrogen-containing atmosphere having an oxygen partial pressure of 10−10 to 10−20 bar.

A clutch actuation device, particularly for a manual transmission of a vehicle, in particular a commercial vehicle, includes a clutch actuation setting device that can be placed in various settings, based on which a corresponding actuation of the clutch takes place. The clutch actuation setting device is suitable for generating electrical signals as a function of the setting, based on which the clutch is correspondingly actuated. A method controls/regulates such a clutch actuation device, particularly for a manual transmission of a vehicle.
