摘要： A coolant pump includes a pump frame, a driving wheel driven by an engine, a pump wheel driven by the driving wheel, and a clutch which couples the driving wheel with the pump wheel. The clutch comprises a friction surface arranged at the driving wheel, and a clutch disc which corresponds to the friction surface. The clutch disk is connected with and co-rotates with the pump wheel, and is axially shiftable between an engaged and a disengaged position. An axial pretension spring pretensions the clutch disc into the disengaged position. A permanent magnet forces the clutch disc into the engaged position. An electromagnet, when energized, generates a polarization which is opposite to a polarization of the permanent magnet to reduce a total magnetic attraction force of the permanent magnet with respect to the clutch disc and to thereby push the clutch disc into the disengaged position via the pretension spring.

摘要： A drive train (1) includes an internal combustion engine (2) and working hydraulics (4) having at least one hydraulic pump (7). When operated as a pump, the hydraulic pump (7) sucks hydraulic fluid from a tank (9) and delivers into a delivery line (10) that leads to the working hydraulics (4). When operated as a motor, the hydraulic pump (7) is supplied with hydraulic fluid from a hydraulic accumulator (25). The drive train (1) has a charge pump (20) to supply a charging circuit (23). The charge pump (20), when operated as a pump, sucks hydraulic fluid out of the tank (9) and delivers into a charge pressure line (22) that leads to a charging circuit (23), and the charge pump (20) when operated as a motor is supplied with hydraulic fluid from the hydraulic accumulator (25).

摘要： Provided is a forced-regeneration treatment method for an exhaust-gas aftertreatment device (DPF) and an associated engine-driven compressor. When the amount of particulate matter (PM) deposited in a filter element of a DPF reaches a predetermined amount and a forced-regeneration start command is input, a capacity controlling means of the engine-driven compressor is disabled to close an intake valve and to open the discharge side of a compressor main unit to atmosphere, thereby causing the compressor main unit to achieve a low-load state. The operation mode of the engine is switched to a predetermined forced-regeneration mode to operate the engine at a predetermined speed and to increase the temperature of the gas. The temperature inside the DPF is increased to reach a temperature at which an oxidative catalyst is activated and to a temperature lower than the self-combustion temperature of the PM, thereby forcibly burning the PM.

摘要： A variable displacement hydrostatic power unit (7) is in a drive connection with an internal combustion engine (2). When operated as a pump, the power unit (7) delivers hydraulic fluid to at least one consumer (V). When operated as a motor, the power unit (7) is a hydraulic starter for the internal combustion engine (2) and is supplied with hydraulic fluid from a hydraulic accumulator (25). The displacement volume of the power unit (7) is set by a displacement volume control device (50) actuated by a positioning device (52). The displacement volume control device (50) is displaced into a position with maximum displacement volume by a corresponding actuation of the positioning device (52) chronologically prior to the shutoff of the internal combustion engine (2). A securing device (60) holds the displacement volume control device (50) in the maximum displacement volume position when the internal combustion engine (2) is shut off.

摘要： An electric brake booster vacuum pump of a vehicle has a deactivation level determined according to a percentage of maximum available vacuum at the instant altitude of the vehicle. The activation level may be determined in the same way. The invention provides for earlier on-switching of a vacuum pump at altitude, while ensuring that the off-switching value is achievable at low atmospheric pressure.

摘要： A method and system for management of a vacuum pump connected to a braking system of a motor vehicle, and use of an electronic control unit connected to the vacuum pump. At least one differential pressure threshold associated with the vacuum pump, selected from a first differential pressure threshold controlling stopping of operation of the vacuum pump, a second differential pressure threshold controlling starting of the vacuum pump, and a third differential pressure threshold, lower than the second threshold and signalling alerts representative of operating faults, is determined by taking into account a first set of data representative of the detection or otherwise of a repetitive braking situation and/or a second set of data representative of altitude of the vehicle.
