Problems solved by technology

[0008] In order to solve the problem that the current pressure changing device requires independent oil supply and has a complicated structure and takes up a large space, the present invention adopts the technical means of borrowing oil from the existing oil supply oil pot and oil pool (actually a deformed oil pot) of the automobile , so as to not only simplify the oil supply method, but also ensure the normal oil supply, which greatly simplifies the process and reduces the cost

Embodiment 1

[0060] Such as Figure 2-7 As shown, an oil circulation device of a pressure changing device includes an oil supply device and a pressure changing device 2; the oil supply device is a gearbox 1; the gearbox 1 includes a housing 101, and the pressure changing device 2 It is fixedly installed in the casing 101 of the gearbox 1 .

[0061] The pressure changing device 2 includes a flange 201, a pump body 202, a negative pressure air inlet 203 and a gas pipe joint 204;

[0062] The flange 201 is arranged on the front end of the pump body 202; the pump body 202 contains a vacuum chamber 205; the negative pressure inlet 203 is arranged on the flange 201, and is connected with the vacuum chamber 205 communicates; the air pipe joint 204 is fixedly installed on the negative pressure air inlet 203; the air pipe joint 204 is connected with the vacuum booster servo braking system circuit to provide negative pressure for the vacuum booster.

[0063] The gearbox 1 is provided with an oil p...

Embodiment 2

[0077] Such as Figure 10-12 As shown, the structural principle of this embodiment is similar to that of Embodiment 1, and the difference with Embodiment 1 is:

[0078] 1) The pressure changing device 2 is fixedly installed outside the casing 101 of the gearbox 1;

[0079] 2) Cancel the pressure changing device mounting plate 206;

[0080] 3) The pressure changing device 2 is added: a pressure changing device housing 2031 , a front support base 2032 and a rear support base 2033 .

[0081] The pressure changing device casing 2031 covers the outside of the pressure changing device 2;

[0082] One side of the front support base 2032 and the rear support base 2033 are fixed on the pressure changing device housing 2031, and the other side is fixed on the housing 101;

[0083] The pressure changing device 2 is fixedly installed outside the casing 101 through the front support base 2032 and the rear support base 2033 .

[0084] Further, the rear support seat 2033 is provided with...

Embodiment 3

[0090] Such as Figure 13-15 As shown, the structural principle of this embodiment is similar to that of Embodiment 2, and the difference with Embodiment 2 is;

[0091] 1) Cancel the oil inlet hole 2034 of the rear support seat;

[0092] 2) The pressure changing device 2 adds a tail support seat 2036, and an oil inlet hole 2037 of the tail support seat is set in the tail support seat 2036 to replace the oil inlet hole 2034 of the rear support seat.

[0093] One end of the oil inlet hole 2037 of the tail support seat communicates with the central hole 2026 of the rotating shaft 2023 , and the other end communicates with the inside of the housing 101 and is below the oil level of the oil pool 102 .

[0094]Due to the effect of vacuum suction, the oil in the gearbox 1 enters the center hole 2026 of the rotating shaft 2023 from the oil inlet hole 2037 of the tail support seat, and the oil in the center hole 2026 is due to negative pressure. Function, through the oil throwing thr...

Description

technical field [0001] The invention relates to the field of vacuum technology, in particular to an oil circulation device and method of a pressure changing device. Background technique [0002] A pressure changing device refers to a device that uses mechanical, physical, chemical or physicochemical methods to pump or inflate a container with an effective volume. [0003] In the automotive field, the pressure changing device is usually used to provide vacuum to the vacuum booster; the servo brake system of the vacuum booster is as figure 1 As shown, the vacuum booster utilizes the pressure difference between the vacuum and the atmosphere to enhance the braking thrust and realize the function of further amplifying the leg strength. [0004] The application of the pressure changing device in conventional fields such as automobiles is usually through the output shaft of the internal combustion engine connected in series with the pressure changing device, and the output power o...
