Abstract

PURPOSE:To reliably and stably attain an effective operating characteristic without a shock at the time of operating a clutch by interlocking a detector with a control valve in such a manner as to come to the quantity of supplied oil previously set corresponding to the rotating speed of an output shaft. CONSTITUTION:Input and output shafts 1, 2 are respectively provided with electromagnetic induction detectors 5, 6 for detecting the rotating speed thereof. Each rotating speed is input as a pulse signal from the detectors 5, 6 to a microcomputer 10. The microcomputer 10 is adapted to compare both pulse signals, calculate the rotating speed of the output shaft 2, calculate the quantity of supplied oil set corresponding to the rotating speed, and adjust a control valve 7 to automatically control the quantity of supplied oil. As the rotating speed of the output shaft is a parameter for feedback control, a clutch can be reliably and stably thrown in regardless of a change in properties of oil caused by temperature.

い欠点があった。In the device with the above configuration, the ITJ actuation pressure control mechanism alleviates the shock caused by the rapid increase in clutch actuation pressure when the clutch is engaged, ensuring the safety of the driver and preventing deformation and damage to the passive mechanism. However, in the past, the working pressure control mechanism with this role generally involves connecting an orifice, accumulator, etc. in the hydraulic pressure supply circuit to the clutch, and controlling the amount of oil supplied to the hydraulic clutch when the clutch is engaged. A mechanism was used to control it. However, with this conventional mechanism, supply due to changes in properties such as viscosity changes due to the temperature of the hydraulic oil! There was a drawback that stable clutch engagement vJ characteristics could not be obtained due to variations in t.

By operating the control pulp ζ, that is, by feedback controlling the control pulp using the rotational speed of the output shaft as a parameter, regardless of changes in oil properties such as changes in viscosity due to temperature. The amount of oil supplied to the hydraulic clutch during clutch engagement is gradually increased within a range that does not cause shock to the transmission VJ mechanism or the driver, etc., thereby achieving smooth latching operation characteristics in a reliable and stable manner. be able to. Furthermore, because the control uses the output shaft rotational speed as a parameter, there is no adverse effect due to disturbances such as clutch plate wear, and the desired working wJ characteristics can be stably obtained.
