Detailed Description
A control system 100 for a vehicle suspension according to an embodiment of the first aspect of the utility model is described below with reference to fig. 1-3.
As shown in fig. 1 to 3, a control system 100 for a vehicle suspension according to an embodiment of the first aspect of the present utility model includes a plurality of airbags 1, a gas storage device 2, and a switch assembly 3. In the description of the present utility model, "plurality" means two or more.
Specifically, the plurality of air bags 1 are connected in series, the air storage device 2 has a first air inlet and a first air outlet 21, the first air inlet is adapted to communicate with a dryer of the vehicle, the first air outlet 21 communicates with the plurality of air bags 1 through the control valve 4, and the switch assembly 3 is electrically connected with the control valve 4. Wherein the control valve 4 is switched between a venting position and an exhaust position and the switch assembly 3 is switched between an idle position and a heavy-duty position. When the switch assembly 3 is in the idle position, the control valve 4 is in the exhaust position, and the plurality of airbags 1 are exhausted to the outside. When the switch assembly 3 is in the heavy load position, the control valve 4 is in the ventilation position, and the gas storage device 2 inflates the plurality of airbags 1.
Specifically, the plurality of air bags 1 are connected in series, the air storage device 2 has a first air inlet and a first air outlet 21, the first air inlet is adapted to communicate with a dryer of the vehicle, the first air outlet 21 communicates with the plurality of air bags 1 through the control valve 4, and the switch assembly 3 is electrically connected with the control valve 4. Wherein the control valve 4 is switched between a venting position and an exhaust position and the switch assembly 3 is switched between an idle position and a heavy-duty position. When the switch assembly 3 is in the idle position, the control valve 4 is in the exhaust position, and the plurality of airbags 1 are exhausted to the outside. When the switch assembly 3 is in the heavy load position, the control valve 4 is in the ventilation position, and the gas storage device 2 inflates the plurality of airbags 1.
For example, in the examples of fig. 1 to 3, two airbags 1 are connected in series, and the two airbags 1 are used for supporting a frame at the time of heavy load, and the support stability and balance of the frame at the time of heavy load are increased. The switch assembly 3 and the control valve 4 cooperate together to control the on-off of the gas storage device 2 and the two air bags 1. The dryer is connected with an air outlet device of the engine, and air generated by the engine of the vehicle enters the air storage device 2 from the dryer and the first air inlet and is stored in the air storage device 2, so that sufficient air is stored in the air storage device 2, and the air in the air storage device 2 can enter the air bag 1 along the first air outlet 21 through the control valve 4, so that the air bag 1 is inflated to be large to support the vehicle frame.
In which, referring to fig. 2 and 3, the gas volumes in the two airbags 1 are controlled to be increased or decreased by switching the control valve 4 between the ventilation position and the exhaust position so as to be suitable for the state in which the vehicle is currently in. Specifically, when the switch assembly 3 is located at the idle position, the control valve 4 controls the air bag 1 to be communicated with the outside atmosphere, so that the air in the air bag 1 can be discharged to the atmosphere, thereby reducing the volume of the air bag 1, avoiding the air bag 1 from deforming for a long time to reduce the deformation effect, and further prolonging the service life of the air bag 1. When the switch assembly 3 is positioned at the heavy load position, the control valve 4 controls the air bag 1 to be communicated with the air storage device 2, so that the air in the air storage device 2 enters the air bag 1 through the control valve 4, and the volume of the air bag 1 is increased to support the frame in the heavy load state. Therefore, whether the air bag 1 is inflated or deflated can be judged by judging that the states of the vehicle are different, so that the air bag 1 can play a bearing role in the heavy load state of the vehicle, and the whole air bag is prevented from acting on the suspension, so that the service life of the suspension can be prolonged.
According to the control system 100 for a vehicle suspension according to the embodiment of the utility model, the switch assembly 3 is switched between the idle position and the heavy load position by switching the control valve 4 between the vent position and the exhaust position, so that the volume of the air bag 1 becomes large to support the vehicle frame in the heavy load state, and the air in the air bag 1 is discharged in the idle state to reduce the volume of the air bag 1, so that the air bag 1 can meet different use requirements of the vehicle in the heavy load state and the idle state, the air bag 1 can play a bearing role in the heavy load state of the vehicle, and the whole air bag 1 is prevented from acting on the suspension, thereby improving the service life of the suspension.
According to some embodiments of the present utility model, referring to fig. 1-3, the switch assembly 3 includes a control switch 31, a first pressure switch 32, and a second pressure switch 33, the control switch 31, the control valve 4, and the first pressure switch 32 are connected in series, and the control switch 31, the control valve 4, and the second pressure switch 33 are connected in series. Wherein the control valve 4 is controlled to switch to the ventilation position when the first pressure switch 32 is in communication with the control switch 31; the second pressure switch 33 is communicated with the control switch 31 to control the control valve 4 to switch to the exhaust position. So set up for control switch 31 cooperates with first pressure switch 32 and second pressure switch 33 respectively in order to control valve 4 in different positions, thereby can promote the switching accuracy of control valve 4.
Further, the first pressure switch 32 is a normally closed pressure switch. When the air pressure in the air bag 1 is lower than the set pressure value of the first pressure switch 32, the first pressure switch 32 is in a closed state, and at the moment, the control switch 31 and the first pressure switch 32 are electrified so as to enable the control valve 4 to be switched to the ventilation position, and the air bag 1 is inflated to enable the air bag 1 to be enlarged; when the air pressure in the air bag 1 reaches the set pressure value of the first pressure switch 32, the first pressure switch 32 is in an off state, and no air is introduced into the air bag 1. The second pressure switch 33 is a normally open pressure switch, and when the air bag 1 is not pressurized, the second pressure switch 33 is in an off state, i.e. the control switch 31 and the second pressure switch 33 are not electrified, and the air bag 1 is not communicated with the external atmosphere; when there is pressure in the air bag 1, the second pressure switch 33 is in a closed state, the control switch 31 and the second pressure switch 33 are energized, and the control valve 4 is switched to an exhaust position, i.e., the air bag 1 is in a communicating state with the outside atmosphere. Thereby, the control accuracy of the entire control system 100 is improved.
According to some embodiments of the present utility model, referring to fig. 2 and 3, the control valve 4 has a second air inlet 411, a second air outlet 412, and an air outlet 413, the second air inlet 411 communicates with the first air outlet 21, the second air outlet 412 communicates with the plurality of air bags 1, and the air outlet 413 communicates with the outside. Wherein, when the control valve 4 is positioned at the exhaust position, the second air outlet 412 is communicated with the air outlet 413; the second air inlet 411 communicates with the second air outlet 412 when the control valve 4 is in the vent position. That is, the control valve 4 is a three-position three-way control valve 4, and the control valve 4 is switched to the exhaust position, so that the gas in the air bag 1 is exhausted to the outside atmosphere through the second gas outlet 412 and the gas outlet 413, thereby reducing the volume of the air bag 1 in the idle state, avoiding the air bag 1 from being expanded for a long time when the air bag 1 is not in operation, further avoiding the deformation of the air bag 1 from being reduced, and prolonging the service life of the air bag 1. By switching the control valve 4 to the ventilation position, the gas in the gas storage device 2 can enter the airbag 1 along the first gas outlet 21, the second gas inlet 411 and the second gas outlet 412, thereby increasing the volume of the airbag 1, so that the airbag 1 is supported at the bottom of the frame, and further increasing the support stability of the frame in a heavy load state.
Further, the control valve 4 includes a valve body 41, a first coil 42, a second coil 43, and a spool 44. The valve body 41 has a second air inlet 411, a second air outlet 412, and an air outlet 413. A first coil 42 and a second coil 43 are provided on the valve body 41, the first coil 42 being connected in series with the first pressure switch 32, the second coil 43 being connected in series with the second pressure switch 33. The spool 44 is movably provided in the valve body 41. When the switch assembly 3 is positioned at the heavy-load position, the first coil 42 is electrified, and the valve core 44 moves to enable the second air inlet 411 to be communicated with the second air outlet 412; when the switch assembly 3 is in the idle position, the second coil 43 is electrified, and the valve core 44 moves to enable the second air outlet 412 to be communicated with the air outlet 413; when the switch assembly 3 is not energized, the valve core 44 blocks the second air inlet 411, the second air outlet 412 and the air outlet 413.
Referring to fig. 1, the second air inlet 411, the second air outlet 412, and the air outlet 413 may all communicate with the inside of the valve body 41 and the outside of the valve body 41. The second air inlet 411 and the second air outlet 412 and the air outlet 413 are provided on opposite sides of the valve body 41, respectively, in a height direction (e.g., up-down direction in fig. 1) of the valve body 41, and the air outlet 413, the second air inlet 411 and the second air outlet 412 are arranged at intervals in a length direction (e.g., left-right direction in fig. 1) of the valve body 41.
Referring to fig. 2, when the switch assembly 3 is in the heavy load position, at this time, the first coil 42 is energized, the first pressure switch 32 is in the closed state, the second pressure switch 33 is in the open state, and the spool 44 moves toward the second coil 43 along the length direction of the valve body 41 until the second air inlet 411 communicates with the second air outlet 412. The gas in the gas storage device 2 enters the airbag 1 along the first gas outlet 21, the second gas inlet 411 and the second gas outlet 412, so that the volume of the airbag 1 is increased, and the airbag 1 can be used for supporting a vehicle frame in a heavy load state. When the air pressure value in the air bag 1 reaches the set pressure value of the first pressure switch 32, the first pressure switch 32 is turned off, the first coil 42 is powered off, and the valve core 44 moves to the initial state (i.e., the valve core 44 seals the second air inlet 411, the second air outlet 412 and the air outlet 413), so that the control valve 4 is prevented from being powered on for a long time in the heavy load state, and damage caused by overheating of the control valve 4 can be avoided.
Referring to fig. 3, when the switch assembly 3 is in the idle state, at which time the second coil 43 is energized, the first pressure switch 32 is in the open state, the second pressure switch 33 is in the closed state, and the spool 44 moves toward the first coil 42 along the length direction of the valve body 41 until the second air outlet 412 communicates with the air outlet 413. The gas in the air bag 1 is discharged to the atmosphere along the second gas outlet 412 and the gas outlet 413, so that the volume of the air bag 1 is reduced, the air bag 1 is prevented from being kept in a large-volume state for a long time in an empty state, the deformation allowance of the air bag 1 is ensured, and the service life of the air bag 1 is further prolonged. When the air pressure value in the air bag 1 reaches the set pressure value of the second pressure switch 33, the second pressure switch 33 is turned off, the second coil 43 is powered off, and the valve core 44 moves to the initial state (i.e., the valve core 44 seals the second air inlet 411, the second air outlet 412 and the air outlet 413), so that the control valve 4 is prevented from being electrified for a long time in the idle state, and further the control valve 4 is prevented from being damaged due to overheating.
