[0032] Example

[0033] This utility model provides an air suspension air supply valve block, which is designed to integrate a booster and various control valves for the air suspension air supply system shown in Figure 1. It is used to control the operation of the air suspension air supply system. The components within the dotted line in Figure 1 can be installed on the air suspension air supply valve block. Of course, in other embodiments, some of the components within the dotted line in Figure 1 or some of the components outside the dotted line can also be installed on the air suspension air supply valve block.

[0034] This utility model discloses an air suspension air supply valve block. By rearranging and combining the positions of various mounting slots, the volume is reduced and the cost is saved. Referring to Figures 1-4, the air suspension air supply valve block may include a valve block body 300. The upper end surface of the valve block body 300 has a first mounting slot 51 for mounting a motor 50. The shape of the first mounting slot 51 can be set to be eccentric if necessary. On both sides of the first mounting slot 51, a second mounting slot 611 for mounting a first pump piston 61 and a third mounting slot 621 for mounting a second pump piston 62 are respectively provided. The second mounting slot 611 and the third mounting slot 621 are symmetrically distributed on both sides of the first mounting slot 51, and one end of the second mounting slot 611 and the third mounting slot 621 are connected to the first mounting slot 51. The other end of the second mounting slot 611 and the third mounting slot 621 extends to the first side and the second side of the valve block body 300.

[0035] The motor 50 and the first pump piston 61 and the second pump piston 62 on its two sides constitute a booster. The lower end face of the valve block body 300 is also provided with a terminal groove 52 for installing the positive and negative terminals of the motor. The terminal groove 52 is connected to the first mounting groove 51.

[0036] The upper end face of the valve block body 300 is provided with an air spring interface 11 for connecting the air spring 10, and the lower end face of the valve block body 300 is provided with a fourth mounting groove 21 for installing the air spring solenoid valve 20; the lower end face of the valve block body 300 is also provided with a fifth mounting groove 311 for installing the air spring three-way valve 31, a sixth mounting groove 321 for installing the pump inlet isolation solenoid valve 32, and a seventh mounting groove for installing the air tank control valve.

[0037] The valve block body 300 has a first connecting channel, a second connecting channel 211, a third connecting channel, and a fourth connecting channel. The two ends of the first connecting channel are respectively connected to the air spring interface 11 and the first connecting port of the fourth mounting groove 21. The two ends of the second connecting channel 211 are respectively connected to the second connecting port of the fourth mounting groove 21 and the first connecting port of the fifth mounting groove 311. The two ends of the third connecting channel are respectively connected to the first connecting port of the sixth mounting groove 321 and the first connecting port of the seventh mounting groove, and the second connecting port of the fifth mounting groove 311 is connected to the third connecting channel. The two ends of the fourth connecting channel are respectively connected to the second connecting port of the seventh mounting groove and the air tank interface 41 for connecting the air tank 40.

[0038] The upper end face of the valve block body 300 is also provided with an air inlet 100 and an exhaust port 200. The valve block body 300 is also provided with a fifth connecting channel 110 and a sixth connecting channel. The two ends of the fifth connecting channel 110 are respectively connected to the air inlet 100 and the first connecting ports of the second mounting slot 611 and the third mounting slot 621. The two ends of the sixth connecting channel are respectively connected to the exhaust port 200 and the second connecting ports of the second mounting slot 611 and the third mounting slot 621. The second connecting port of the sixth mounting slot 321 is also connected to the fifth connecting channel 110. The third connecting port of the fifth mounting slot 311 is also connected to the sixth connecting channel.

[0039] By selecting the positions of the booster pump, air spring 10, air spring solenoid valve 20, air spring three-way valve 31, pump inlet isolation solenoid valve 32, and air tank control valve, the connection channels between the corresponding mating components can be shortened and made easier to manufacture. Simultaneously, the overall volume of the valve block body 300 can be significantly reduced. For example, referring to Figure 4, since the second connection channel 211 connects the fourth mounting slot 21 and the fifth mounting slot 311, the positions of the fourth mounting slot 21 and the fifth mounting slot 311 can be designed to be closer together.

[0040] It is understandable that the connection ports on each mounting slot are adapted to the interface positions on the corresponding devices, so that gas can be supplied through the connection ports on the mounting slots when the corresponding devices are working. For example, the two connection ports on the third mounting slot 621 correspond to the inlet and outlet of the air spring solenoid valve 20, respectively, and the three connection ports on the fifth mounting slot 311 correspond to the common interface, normally closed interface, and normally open interface of the air spring three-way valve 31, respectively.

[0041] There can be multiple air springs 10. There are four air springs 10 in Figure 1, which correspond to the four wheels respectively. Therefore, there are four air spring interfaces 11, first connecting channels and fourth mounting slots 21, which correspond one to one. Each air spring interface 11 is connected to the corresponding fourth mounting slot 21 through the corresponding first connecting channel.

[0042] The air tank interface 41 can also be set on the upper end face of the valve block body 300, so that the air intake interface 100, the exhaust interface 200 and the air tank 40 are all set on the upper end face of the valve block body 300, which can prevent the valve block body 300 from shaking during driving.

[0043] A first check valve 91 is also provided on the fifth connection channel 110. The lower end face of the valve block body 300 is also provided with an eighth mounting groove 71 for installing a safety valve 70.

The second connection port of the eighth mounting groove 71 is connected to the fifth connection channel 110 between the air inlet 100 and the first check valve 91. The third connection port of the eighth mounting groove 71 is connected to the sixth connection channel. The second connection port of the sixth mounting groove 321 is connected to the fifth connection channel 110 between the first connection ports of the second mounting groove 611 and the third mounting groove 621 and the first check valve 91. An external air filter 92 can also be installed on the air inlet.

[0044] The second side of the valve block body 300 is also provided with a dryer air inlet 81 and a dryer air outlet 82. The sixth connection channel includes a sixth first connection channel and a sixth second connection channel. The dryer air inlet 81 and the dryer air outlet 82 are respectively used to connect to the air inlet and air outlet of the dryer 80 (that is, the dryer 80 is placed outside the valve block body 300). The two ends of the sixth first connection channel are respectively connected to the dryer air inlet 81 and the third connection port of the fifth mounting groove 311. The sixth second connection channel is a three-end interface, and its three-end interface is respectively connected to the dryer air outlet 82, the exhaust port 200, and the second connection ports of the second mounting groove 611 and the third mounting groove 621.

[0045] The lower end face of the valve block body 300 is also provided with a ninth mounting groove 351 for installing the exhaust solenoid valve 35. The two connection ports of the ninth mounting groove 351 are respectively connected to the exhaust port 200 and the sixth second connection channel.
