Embodiment Construction

[0031] In the transmission system of a car, the clutch is located between the engine and the transmission and is responsible for cutting and engaging the power of the engine. Normally, the crankshaft of the engine is assembled with the flywheel of the clutch, and the output shaft of the clutch is connected with the input shaft of the transmission, so that the power stored on the flywheel can be transmitted to the transmission during engine start.

[0032] In practical applications, the clutch includes: a driving mechanism, a driven mechanism, a pressing mechanism and an operating mechanism. Among them, the active mechanism can include a driving disc and a flywheel, the driven mechanism can include a driven disc and an output shaft, the pressing mechanism is mainly composed of a coil spring or a diaphragm spring, and the operating mechanism can include a release bearing for operating the driving disc and the driven disc. The part that engages or disengages the disc. A certain ...

Abstract

A dry clutch torque transmission starting point detection method and device are disclosed. The method includes the steps of applying a pressure to a pressing mechanism of a dry clutch so that the pressing mechanism moves in an axial direction; and determining a starting point of the torque transmission of the dry clutch according to a change in the rotation speed of a driven plate. With the abovescheme, the starting point of the torque transmission of the dry clutch can be detected.

Description

technical field [0001] The invention relates to the technical field of dry clutches, in particular to a method and device for detecting the starting point of torque transmission of a dry clutch. Background technique [0002] In the transmission system of a car, the clutch is located between the engine and the transmission, responsible for cutting off and engaging the power of the engine, which can ensure the smoothness of the car when starting and smooth shifting. Generally, clutches can be divided into dry clutches and wet clutches. Among them, the dry clutch uses air to cool its surface temperature, while the wet clutch uses oil to cool its surface temperature. [0003] In practical applications, dry clutches have the advantages of high transmission efficiency and low cost, but their control strategies are quite complicated. The starting point of dry clutch torque transmission, that is, the Kisspoint point, is used as the starting point for the clutch to transmit torque....
