Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] see figure 1 , a double-gain automotive clutch control system, including a main pressure source 1, a variable solenoid valve 2, a regulating valve 3, a booster valve 4 and a clutch 5; the clutch is provided with a pressure oil chamber 5a, which passes through a clutch pressure oil passage 7 is connected to the oil outlet of the regulating valve 3, and the regulating valve 3 is connected to the main pressure source 1 through an oil supply passage 6; the clutch regulating valve 3 controls the pressure oil under the control of the clutch control pressure 8 The pressure in chamber 5a is controlled.

[0014] The clutch regulating valve 3 includes a regulating valve body 3n, a regulating valve spool 3o and a regulating valve spring 3m, the regulating valve body 3n is provided with a regulating valve hole, and the regulating valve spool 3o is slidably ...

Abstract

The invention discloses a double-gain clutch control system of automobiles, which comprises a main pressure source, a variable electromagnetic valve, a clutch regulating valve, a gain control device and a cutch. The clutch is provided with a pressure oil chamber which is connected to the regulating valve oil outlet of the clutch regulating valve through a clutch pressure oil passage; the clutch regulating valve is connected to the main pressure source through an oil-supply oil passage; the gain control device comprises a pressure increasing valve, a trigger pressure oil passage, a clutch control oil passage, a gain control oil passage and an oil outlet, is connected to the clutch regulating valve through the clutch control oil passage and the gain control oil passage and controls the gain of a clutch control pressure according to the signals of the trigger pressure oil passage so that the clutch has a high gain for a high torque and has a low gain for a low torque. Therefore, the automatic gearbox has a high torque range at a low speed and has a better gear-shifting quality at a high speed.

Description

technical field [0001] The invention relates to an automobile automatic transmission system, in particular to a clutch control system in the automobile automatic transmission system, which is used for controlling the clutch state of the clutch when the automatic transmission changes the speed ratio. Background technique [0002] Automobile automatic transmission systems generally have multiple torque transmission mechanisms, which are commonly referred to as clutches, and the speed ratio of the automatic transmission is converted through the clutch action of the clutches. When the speed ratio of the automatic transmission is converted, the clutch has a slipping process, which makes the conversion of the speed ratio smooth and smooth. [0003] The clutch typically includes a hydraulically actuated piston that is pressured by the output pressure of a clutch regulator valve. The regulating valve controls the rise and fall of the pressure in a control mode, so as to ensure the ...
