Problems solved by technology

When selecting the type of hydraulic oil pump, it is necessary to meet the comprehensive requirements of clutch cooling flow and shaft cooling flow. The flow is uncontrollable, which leads to the selection of an oversized oil pump to ensure adequate cooling flow to the clutch, which reduces the efficiency of the transmission

Embodiment 1

[0044] The embodiment of the present invention discloses a cooling control valve 1, such as Figure 1-Figure 2 As shown, the cooling control valve 1 includes a valve housing 11 , a valve core 12 and a driver 14 , the valve housing 11 is provided with a valve core 12 , and the valve core 12 is connected to the driver 14 . Optionally, the valve casing 11 is provided with a first oil inlet 111, a second oil inlet 112, a first oil outlet 113 and a second oil outlet 114, and the first oil inlet 111 and the second oil inlet 112 , the first oil inlet 111 can communicate with the first oil outlet 113 , and the second oil inlet 112 can communicate with the second oil outlet 114 . The spool 12 is movably inserted into the valve casing 11, the spool 12 is provided with a first stopper 121 and a second stopper 122, and an oil passage is provided between the first stopper 121 and the second stopper 122 123 , the oil passage 123 communicates with both the first oil inlet 111 and the second...

Embodiment 2

[0077] In this embodiment, the parts that are the same as in the first embodiment are given the same reference numerals, and the same text descriptions are omitted.

[0078] Figure 4 It is a schematic diagram of the principle of a cooling control valve 1 provided in the second embodiment, as Figure 4 As shown, compared with Embodiment 1, the cooling control valve 1 provided by this embodiment has the following difference: the driving member 14 is a pilot solenoid valve, and the pilot solenoid valve is connected to the valve core 12. By controlling the magnitude of the current of the pilot solenoid valve, that is The cooling flow can be adjusted, and the adjustment principle is the same as that of the electromagnet, which will not be repeated here. In addition, the structure of the pilot solenoid valve is a prior art, and will not be repeated here.

[0079] further, Figure 5 It is a schematic diagram of the principle of a dual-clutch transmission cooling system 2 provided...

Abstract

The invention discloses a cooling control valve, a control method, a dual-clutch transmission cooling system and a vehicle, and relates to the technical field of vehicle cooling control. The cooling control valve comprises: a valve shell provided with a first oil inlet, a second oil inlet, a first oil outlet and a second oil outlet, wherein the first oil inlet communicates with the second oil inlet, and the first oil inlet and the second oil inlet can communicate with the first oil outlet and the second oil outlet, respectively; a valve element movably inserted into the valve shell and provided with a first check block and a second check block, wherein an oil passing channel communicating with the first oil inlet and the second oil inlet is arranged between the first check block and the second check block, and the first oil outlet and the second oil outlet can communicate with the oil passing channel; and a driving piece connected with an external power source, is in transmission connection with the valve element, and capable of driving the valve element to move so that the first check block and the second check block can shield or avoid the second oil outlet and the first oil outlet, respectively. The structure is simplified, the cost is saved, the power loss is reduced, and the transmission efficiency is ensured.

Description

technical field [0001] The invention relates to the technical field of vehicle cooling control, in particular to a cooling control valve, a control method, a dual-clutch transmission cooling system and a vehicle. Background technique [0002] At present, most vehicles begin to use dual-clutch automatic transmissions. The adoption of dual-clutch automatic transmissions can make the overall structure of the gearbox body more compact and have a greater torque transmission capacity. However, when the dual-clutch transmission is working, both the clutch and the shafting will generate a lot of heat, and cooling oil is needed to cool the clutch and the shafting in real time to ensure normal operation. [0003] At present, the technical solution generally adopted is: according to the working conditions, the cooling oil flow of the clutch is controlled in real time through a solenoid valve, and the cooling flow of the shaft system is limited by an orifice, which is basically maintain...
