Description

Air drier for air suspension of electric vehicle

The present invention relates to an adsorption-type air dryer device for an air suspension of an electric vehicle, and more specifically, an air suspension of an electric vehicle, which can reduce fuel consumption by not only reducing volume but also reducing weight by incorporating a silencer in a body. It relates to an adsorption type air dryer device.

As fossil fuels become depleted, electric vehicles are being developed that use electric energy stored in batteries instead of vehicles using fossil fuels such as gasoline and light oil to drive the motor.

The electric vehicle includes a pure electric vehicle driving a motor using only electric energy stored in a rechargeable battery, a solar cell vehicle driving a motor using photovoltaic cells, and a fuel driving motor using a fuel cell using hydrogen fuel. It is divided into a battery vehicle and a hybrid vehicle using an engine and a motor by driving an engine using fossil fuels and driving a motor using electricity.

In general, an adsorptive air dryer is used for the air suspension installed in the electric vehicle.

As shown in Figs. 1 to 3, the structure of the adsorption-type air dryer device for air suspension of a conventional electric vehicle includes a body 10 having an inlet 1, an outlet 4, and a vent hole 6 formed therein. ), An outer cartridge (2) installed at the inlet (1), an inner cartridge (3) installed inside the outer cartridge (2) and filled with a dehumidifying agent therein, and the body described above. The solenoid valve 5 for controlling the connection of the inlet 1, the outlet 4, and the vent hole 6 of the 10, and the regeneration air inputted through the vent hole 6 above the predetermined pressure. And a pilot valve 7 for passing it through, a vent hose 8 for discharging the regenerated air, and a lower portion of the vent hose 8 and filled with a sound absorbing material 9c. The silencer 9 for reducing and the silencer 9 described above to the vent hose 8 described above. It comprises a clamp 12 for fixing.

The solenoid valve 5 is composed of a 2-way 3-port.

The pilot valve 7 has a structure in which the regeneration air input through the vent hole 6 passes therethrough when it is larger than the elastic force of the spring 11.

The silencer 9 includes an upper case 9a, a lower case 9b, and a sound absorbing material 9c provided between the upper case 9a and the lower case 9b.

The function of the adsorption type air dryer apparatus of the conventional electric vehicle by the above structure is as follows.

Compressed air entering through the inlet 1 of the body 10 as shown by the arrow shown in FIG. 2 by pneumatic pressure generated from an air compressor (not shown) is formed between the inner cartridge 3 and the outer cartridge 2. Moisture is removed by the dehumidifier filled in the interior of the inner cartridge (3) after ascending through the space of the inner cartridge (3).

In this way, the compressed air from which the moisture is removed from the internal cartridge 3 is stored and moved to the air tank (not shown) through the outlet 4 via the solenoid valve 5. In this case, the vent hole 6 remains blocked by the solenoid valve 5.

Once the air tank (not shown) is filled, it must be regenerated to remove moisture absorbed by the dehumidifier during the dehumidification process described above. The regeneration process is an important method of maintaining the dehumidifying performance of the dehumidifying agent by maintaining the dehumidifying performance of the dehumidifying agent by circulating the dried air stored in the regeneration tank (not shown) to release moisture absorbed from the compressed air into the atmosphere during the dehumidifying process. Play a role.

When the vent hole 6 is opened by operating the solenoid valve 5 for regeneration, the high-pressure dried air of 9.5 bar stored in the regeneration tank (not shown) is shown as an arrow shown in FIG. As it flows backward, it flows into the inner cartridge 3 to take out the moisture contained in the dehumidifying agent of the inner cartridge 3, pushes the pilot valve 7 through the vent hole 6, Through the silencer 9 and discharged into the air.

As described above, in the regeneration process, the high pressure air stored in the regeneration tank (not shown) exits the air through the vent hose 8 through the internal cartridge 3, at which time the speed of the air is very fast and the noise is high. Since the muffler (9) serves to reduce this noise.

However, the above-described adsorption type air dryer device for an air suspension of an electric vehicle has a problem that fuel efficiency is increased by increasing the weight as well as increasing the volume because the silencer is installed outside the body.

An object of the present invention is to solve the conventional problems as described above, by incorporating a silencer in the body can not only reduce the volume but also reduce fuel consumption by weight reduction, adsorption air dryer for air suspension of electric vehicles To provide a device.

It is preferable to include a pilot-safety valve, a silencer installed inside the body and filled with a sound absorbing material to reduce vent noise, and a C ring for fixing the silencer inside the body. Do.

It is preferable that the configuration of the present invention further comprises a flow rate control valve for adjusting the flow rate of the air passing through the inner cartridge.

It is preferable that the structure of this invention further includes the check valve provided in the said vent hole and preventing a backflow.

And a solenoid valve 25 for controlling the connection of the inlet and outlet of the body 30 and the vent hole 26 to adjust the flow rate of the air passing through A check valve 35 installed in the vent hole 26 to prevent backflow, and a pilot-safety valve 27 passing the regenerated air inputted through the vent hole 26 when it exceeds a predetermined pressure. And, installed in the interior of the body 30 A silencer 29 for reducing vent noise, a C ring 32 for fixing the silencer 29 to the inside of the body 30, and a freezing of the dehumidifying agent. It comprises a heater 36 to prevent the.

The outer circumferential surface of the inner cartridge 23 has a structure in which a spacer portion 231 for protruding the outer cartridge 22 is formed to protrude.

The solenoid valve 25 is made of a 2-way 3-port and has a structure for varying the air passage using the plunger 34.

The pilot-safety valve 27 is configured to pass the regeneration air input through the vent hole when it is larger than the elastic force of the spring 31.

According to the above configuration, the action of the adsorption type air dryer device for an air suspension of an electric vehicle according to an embodiment of the present invention is as follows.

Compressed air entering through the inlet of the body 30 by pneumatic pressure generated from an air compressor (not shown) rises through the space between the inner cartridge 23 and the outer cartridge 22, After entering, moisture is removed by the dehumidifying agent filled in the inner cartridge 23.

As such, the compressed air from which the moisture is removed from the inner cartridge 23 is stored and moved to the air tank (not shown) through the outlet via the solenoid valve 25. In this case, the vent hole 26 remains blocked by the solenoid valve 25.

After the air tank (not shown) is filled, a regeneration process is performed to remove moisture absorbed by the dehumidifying agent during the dehumidification process described above, and the vent hole 26 is operated by operating the solenoid valve 25 for regeneration. When opened, the high-pressure dried air of 9.5 bar stored in the regeneration tank (not shown) flows back into the inner cartridge 23 while flowing backward as shown by the arrow shown in FIG. After the moisture contained in the dehumidifying agent of) is taken off, it is discharged into the vent hole 26. At this time, the flow control valve 33 allows the air of a relatively low flow rate to flow into the inner cartridge 23 than during regeneration.

The air introduced into the vent hole 26 pushes the pilot valve 27 and is discharged into the air through the silencer 29 while preventing backflow by the check valve 35.

In the regeneration process as described above, the high-pressure air stored in the regeneration tank (not shown) is discharged into the air through the silencer 29 through the internal cartridge 23. At this time, the speed of the air is very fast, and the noise is removed. The muffler 29 serves to reduce such noise.

On the other hand, the heater 36 provides heat to prevent freezing of the dehumidifier when the weather is cold.
