Abstract:
The invention concerns an automatic clutch (2) in the drive train of a motor vehicle having a manual or voluntarily changed transmission (3). The clutch (2) is set at a very low transmissible torque when a pedal used to control the load on the engine (1) is not activated and a gear of the transmission (3) is engaged. In this way, a creep tendency desired for manoeuvring the vehicle is brought about.
Abstract:
Bekannte Zweimassenschwungräder stossen hinsichtlich des Entkopplungsgrades, vor allem für drehmomentstarke Brennkraftmaschinen mit starker Drehungleichförmigkeit, an ihre Grenzen. Erfindungsgemäss werden zwei Torsionsdämpfer (18b, 52) in Reihenschaltung und axial hintereinanderliegend angeordnet, ggf. unter Ergänzung eines dritten Torsionsdämpfers (17b) radial aussenliegend von den vorgenannten Torsionsdämpfern (18b, 52). Hierdurch sind weich abgestimmte Zweimassenschwungräder ermöglicht mit grossen Federwegen, welche gleichzeitig radial klein bauen.
Abstract:
The invention concerns an automatic clutch in the drive train of a motor vehicle having a transmission with manual or voluntary selection of the different gears. After a gear-change, the engagement of the clutch is controlled as a function of the shift speed during the gear-change, such that, at high shift speeds, only a shortened clutch slip phase can occur.
Abstract:
The invention concerns an automatic clutch in a motor vehicle drive train. According to the invention, differences in the speeds of rotation between the clutch input and clutch output are determined by computer from the speeds of rotation of the vehicle engine, on the one hand, and the speeds of rotation of the vehicle drive wheels, on the other, variations of a frequency characteristic of resonant frequencies in the drive train when the clutch is engaged not being taken into account.
Abstract:
The invention relates to a control system, in particular an emergency control system, of an automatic clutch. The clutch can operate with slip controlled by the driving speed when engaged, or can be disengaged or remain disengaged when the engine speed is excessive, and can also be disengaged when there is an idling signal.
Abstract:
Disclosed is an automatic clutch (2) for an engine-transmission unit in a vehicle with random gear changing (3). A sensor technology is used for determining the parameters to be taken into account for the automated clutch control (2). The sensing device includes a speed or driving notch display (3), so that, when normally changing the gear or driving notch, the transition over the neutral gear or idle is not displayed.
Abstract:
Disclosed is an automatic clutch intended for use in an engine-transmission unit of a vehicle. When starting up, the clutch transmits first a high torque for a very slow speed, which is then reduced after a set lapse of time if a threshold value is exceeded.
Abstract:
The invention concerns an automatic clutch (2) between a motor vehicle engine (1) and drive train with a manually shifted gearbox (3) disposed on the clutch output side. Rotational speed differences between the clutch input and output detected by sensor technology are taken into consideration when the clutch (2) is engaged. If the signals from the sensing elements for the rotational speed on the output side fail, replacement signals are calculated from other parameters.
Abstract:
The invention concerns an automatic clutch in a motor vehicle drive train. An automatic control device constantly determines values for the travel of an adjusting unit actuating the clutch and associated values of the moment transmitted by the clutch in order to establish whether the travel available is sufficient to reach a threshold value of the transmitted coupling moment. A warning signal is optionally emitted.
Abstract:
The invention concerns an automatic clutch in a motor vehicle drive train. During travel, the clutch is controlled with excess contact pressure such that the transmissible moment of the clutch exceeds the engine torque by a predetermined amount. At low speeds or in low gears and/or when travelling slowly, the amount of excess contact pressure is considerably reduced. At high speeds or in high gears and/or at when travelling fast, the clutch is set at the maximum transmissible moment.
