Abstract

The invention discloses a simulation system for a diaphragm spring of a clutch, which comprises an electronic control unit, a hydraulic control subsystem and a clutch control subsystem, wherein the hydraulic control subsystem comprises an oil tank, a constant delivery pump and a motor; the clutch control subsystem comprises a clutch control cylinder, a first pressure sensor arranged on the clutch control cylinder, and a proportional pressure valve arranged on the clutch control cylinder and used for controlling the pressure in the clutch control cylinder according to a differential value between the actual pressure in the clutch control cylinder and the preset target pressure so as to make the controlled actual pressure reach the target pressure; and the target pressure serves as load resistance of the diaphragm spring of the clutch. Compared with the prior art, the simulation system for the diaphragm spring of the clutch can simulate load resistance of different types of diaphragm springs of clutches.

Description

technical field [0001] The invention relates to a simulation system of a clutch diaphragm spring. Background technique [0002] With the rapid development of automobile technology, various forms of vehicle automatic transmission devices have emerged, mainly including: hydraulic mechanical automatic transmission (AT), mechanical continuously variable transmission (CVT) and electromechanical automatic transmission (AMT). . Among them, AMT transmission combines the characteristics of automatic shifting of automatic transmission and high transmission efficiency of manual transmission, and has the advantages of high fuel economy, low emission and protection of existing manual transmission production investment required by the development of the automobile industry. favored by manufacturers. [0003] figure 1 A schematic diagram showing the simulation system for the clutch diaphragm spring in a prior art AMT transmission. Such as figure 1 Said, including fuel tank 10, quantit...
