Abstract

The invention provides a hydraulic control device with double clutches, belonging to the technical field of an automobile transmission. The hydraulic control device provided by the invention solves the technical problems of larger cost and the like when the breakdown of an electromagnetic pressure proportional valve is eliminated in the prior art. The hydraulic control device with the double clutches comprises an oil tank, an oil pump, an electromagnetic pressure proportional valve 1, a clutch 1, an electromagnetic pressure proportional valve 2, a clutch 2, and two one-way pressure valves, wherein the oil outlets of the electromagnetic pressure proportional valve 1 and the electromagnetic pressure proportional valve 2 are respectively connected with the clutch 1 and the clutch 2; the oil can flow through the one-way pressure valves in the device in a one-way mode when the oil pressure is larger than a set value; and the oil outlet of the oil pump is also connected with a pressure regulating unit capable of regulating the oil pressure in the position of the oil outlet. The hydraulic control device provided by the invention has the advantage of extremely simple structure and can solve the corresponding clutch unloading problem after the breakdown of the electromagnetic pressure proportional valve 1 or the electromagnetic pressure proportional valve 2 occurs only by adopting the bypass one-way pressure valves, and the cost of parts is quite low.

Description

technical field [0001] The invention belongs to the technical field of automobile transmissions, and relates to a hydraulic control device for a double clutch. Background technique [0002] In the currently applied dual-clutch hydraulic control system, the electromagnetic pressure proportional valve is generally used to control the clutch action, but the electromagnetic pressure proportional valve is prone to failure after working for a long time. When the electromagnetic pressure proportional valve fails, it will not be able to drive normally. The clutch it controls completes the remaining actions. When there is low-pressure oil in the clutch, the clutch will not work at most, but when there is high-pressure oil in the clutch, the clutch will continue to work. At this time, it is easy to make the car appear dangerous. [0003] In order to solve this problem, general automobile manufacturers will add an adjustment unit that can properly change the oil circuit when the electr...
