Embodiment 1

[0034] like image 3 and Figure 4 As shown, the first oil hole (1) to the ninth oil hole (9) are a tandem oil hole, the tenth oil hole (10) to the nineteenth oil hole (19) are a tandem oil hole, the second oil hole (10) The tenth oil hole (20) to the thirtieth oil hole (30) are a series of oil holes. Figure 7 and Figure 8 The three rows of grooves on the valve core correspond to each other, and the three rows of grooves in the movement of the valve body interact with the oil holes on the valve body, with the same width and different heights.

[0035] Figure 7 The middle two longitudinal grooves and image 3 The two columns of oil holes in the corresponding Figure 8 grooves in the Figure 4Corresponding to the oil hole in the center, the groove matches the oil hole, so that the transmission oil from the transmission oil pump through the oil inlet hole of the main oil circuit passes through the groove on the surface of the spool, and then enters the clutch or brake oi...

Embodiment 2

[0038] When shifting is required, when changing from the D1 gear in Embodiment 1 to the D2 gear, you only need to move the spool from Figure 11 position towards Figure 12 The position can be moved, when moved to Figure 12 position, image 3 Among them, the oil hole 5 and the oil hole 6 communicate through the groove of the spool, because there is a fifty-first oil passage (51) between the fifth oil hole (5) and the seventh oil hole (7), so the sixth oil hole The transmission oil in (6) will enter the C1 clutch through the fifth oil hole (5) and the seventh oil hole (7); the fifteenth oil passage (15) and the sixteenth oil passage (16) will pass through the The grooves communicate. Because the sixteenth oil hole (16) is the oil inlet hole of the main oil passage, and the fifteenth oil passage (15) is the oil inlet hole of the B2 brake, so when the fifteenth oil hole (15) and the sixteenth oil hole (16 ) is connected, the B2 brake will get enough oil pressure to work. At ...

Embodiment 3

[0043] As shown in the chart of embodiment 2, the gears provided in embodiment 1 and embodiment 2 are D1 gear and D2 gear, when the spool continues to move to Figure 13 In the position shown, the image 3 The fourth oil hole (4) and the fifth oil hole (5) communicate through the spool, the fourth oil hole (4) is the oil inlet hole of the main oil circuit, and the fifth oil hole (5) is the C1 clutch oil inlet; Figure 4 The twenty-fourth oil hole (24) and the twenty-fifth oil hole (25) communicate through the spool, the twenty-fifth oil hole (25) is the oil inlet hole of the main oil circuit, and the twenty-fifth oil hole (25 ) position B1 brake oil inlet, now C1 clutch and B1 brake work, as shown in the chart in embodiment 2, it is D3 block.

[0044] When the spool moves to Figure 14 In the position shown, the image 3 The third oil hole (3), the fourth oil hole (4) and the fifth oil hole (5) communicate through the spool. At this time, the third oil hole (3) is the C2 cl...

Abstract

The invention relates to a novel vehicle automatic transmission gear shifting valve; and the device is a novel gear shifting mechanism for controlling an actuation mechanism of an automatic transmission to open and close a clutch or a brake. The automatic transmission gear shifting valve consists of three elements, wherein the three elements include a valve body, a valve element and a valve cover. The automatic transmission gear shifting valve abandons a traditional electromagnetic valve control mode; the traditional electromagnetic valve control mode needs more electromagnetic valves, a more precise manufacturing technology and a complicated control computer; the automatic transmission gear shifting valve adopts a power source to control the valve element, so that the valve element to move in the valve body; the gear shifting is realized through the hole channel matching between the valve element and the valve body; and the automatic transmission gear shifting valve has such characteristics as low cost, simple structure, more precise control and no impact on a hydraulic system.

Description

technical field [0001] The invention relates to a new automatic transmission shifting device, especially an automatic transmission shifting valve with outstanding advantages in the space and cost of the automatic transmission. Background technique [0002] Currently recognized automatic transmission shift valve body is composed of multiple solenoid valves to control the entire automatic transmission, including one-way valve, pilot solenoid valve or PWM solenoid valve, etc. The control of multiple solenoid valves requires the entire control system Higher requirements, and most automatic transmission control systems are controlled by large foreign companies, such as Germany's Siemens, Dr., Japan's Denso, and the United States' Delphi. Now that the market demands more and more gears for automatic transmissions, the space required for placing solenoid valves will also increase, the number of solenoid valves will increase, and the cost will rise accordingly. The requirements for...
