Abstract
The utility model relates to a system for controlling a following-up axle of an air suspension frame, and the system comprises an air bag inflating switch, a steering locking relay, an air bag inflating solenoid valve, a steering locking solenoid valve, a braking control solenoid valve, a small lamp switch, a reverse gear switch, a steering locking switch and related circuits and pipelines. A driver can operate the air bag inflating switch to realize inflation and deflation of an air bag loaded by the following-up axle of the air suspension frame as well as the opening and closing of the braking function of the following-up axle; through operating the steering locking switch or automatically sensing a reversing signal by the system, the opening and closing of the reversing function of the following-up axle are realized. And the air bag inflating switch and the steering locking switch are provided with indicator lamps for indicating the work state of the system. The system provided by the utility model has the advantages of simple structure, convenience for operation, low cost, high reliability and convenience for maintenance and detection.
Description
Technical field
The utility model belongs to automobile technical field, is specifically related to a kind of air suspension follow-up bridge control system of automobile.
Background technology
Air suspension has experienced the development in a century since being born from 19th-century mid-term, has experienced multiple variation such as " steel spring → air bag compound suspension → passive full air suspension → active be air suspensions (being ECAS electronic control air suspension system) entirely ".Just be used on bogie, motorcoach, small passenger car and the railway automobile to nineteen fifties.External senior motorcoach almost all uses air suspension at present, and heavy duty truck uses the ratio of air suspension to reach more than 80%.For its control system of different suspension systems bigger difference is arranged also.
The involved air suspension follow-up bridge of the utility model belongs to the air bag compound suspension, is used for the jackshaft of 8 * 2 goods carrying vehicles.Lean on a sense set controller to end to the control of the air bag of jackshaft and braking in the existing technology, the sense set controller is ventilated air bag electromagnetic valve and control of braking electromagnetic valve when vehicle load surpasses setting value, for airbag aeration and make jackshaft that braking potential arranged.Cost is higher when adopting this mode, the big poor reliability of the error of sense set controller, and do not have indicator lamp to show the state of suspension.
Summary of the invention
The utility model purpose is to provide a kind of control system of air suspension follow-up bridge of simple in structure, with low cost, 8 * 2 goods carrying vehicles that reliability is high.
The technical scheme of the utility model is following:
Said a kind of air suspension follow-up bridge control system comprises airbag aeration switch SW 2, turns to locking relay R EL1, airbag aeration electromagnetic valve SV1, turns to lock-up solenoid valve SV3, control of braking electromagnetic valve SV2, lampet switch SW 1, the switch SW of reversing gear 3, turns to locking switch SW 4 and relevant circuit and pipeline;
Series arm one end after the control coil of the control coil of airbag aeration electromagnetic valve SV1, control of braking electromagnetic valve SV2, sustained diode 4 parallel connections is connected with positive source, and the other end is connected with air bag gas-filled switching tube SW2; Airbag aeration switch SW 2 other end power connection ground;
Turn to the control coil of lock-up solenoid valve SV3 and the parallel branch after sustained diode 5 parallel connections, a termination power is anodal, the other end with turn to locking switch SW 4 to be connected; Turn to locking switch SW 4 other end power connection ground; Turn to a pair of open contact of locking relay R EL1 and turn to 4 parallel connections of locking switch SW;
Turn to the control coil and switch SW 3 series connection of reversing gear of locking relay R EL1, this series arm one end is connected with positive source, other end power connection ground.
On the airbag aeration switch SW 2 with turn to the indicator lamp that the indicating system mode of operation all is installed on the locking switch SW 4.
The utility model has been cancelled the sense set controller in the former control system; Charge and discharge gas and braking function with what the button switch of driver side was controlled the jackshaft air bag fully; Chaufeur is controlled the mode of operation of jackshaft flexibly according to road conditions and vehicle load situation, and system architecture is simple, and is with low cost; Reliability is high, and indicator lamp is arranged on the switch.The utility model has also increased the control that jackshaft is turned to function, is applicable to the follow-up bridge of band follow-up steering function.
Description of drawings
Fig. 1 is the utility model systematic schematic diagram.
The specific embodiment
Below in conjunction with Fig. 1 the utility model is further specified.
When vehicle at full load chaufeur starts airbag aeration switch SW 2; Airbag aeration electromagnetic valve SV1 and control of braking electromagnetic valve SV2 energising conducting; This moment, follow-up bridge carried airbag aeration; The compressed air brake cylinder inflation, follow-up bridge has load-carrying capacity and braking potential, and the indicator lamp D3 on the airbag aeration switch lights at this moment.Chaufeur is closed airbag aeration switch SW 2 when vehicle is unloaded; Airbag aeration electromagnetic valve SV1 and control of braking electromagnetic valve SV2 close, and this moment, follow-up bridge carried air bag deflation, the compressed air brake cylinder venting; Follow-up bridge does not have load-carrying capacity and braking potential, and the indicator lamp D3 on the airbag aeration switch extinguishes at this moment.The chaufeur startup turns to locking switch SW 4 when vehicle ' is on the road surface of jolting; Turn to lock-up solenoid valve SV3 energising conducting this moment; Turn to the inflation of locking air chamber; Follow-up bridge turn to function by locking, the wheel on the follow-up bridge can not be swung with turn inside diameter, this moment turn to the indicator lamp D6 on the locking switch to light.When vehicle ' during in flat road surface chaufeur close and turn to locking switch SW 4; Turn to lock-up solenoid valve SV3 to close this moment; Turn to the venting of locking air chamber; The function that turns to of follow-up bridge is opened, and the wheel on the follow-up bridge can be swung with turn inside diameter, and turn to the indicator lamp D6 on the locking switch to extinguish this moment.When vehicle is moveed backward; The switch SW 3 of reversing gear on the change speed gear box makes and turns to locking relay R EL1 energising; Relay closes makes and turns to lock-up solenoid valve SV3 energising conducting; Follow-up bridge turn to function by locking, the wheel on the follow-up bridge can not be swung with turn inside diameter, this moment turn to the indicator lamp D6 on the locking switch to light.Light-emitting diode D3 in the system, D6 adopt paster type light emitting type BL-HZH32X-TRB as the mode of operation of indicator lamp indicating system.Diode D4 in the system, D5 are flywheel diode, adopt HDIODE-H1-2P, the inverse electromotive force that produces when being used to absorb the electromagnetic valve outage, and protection diode D3, D6 are not breakdown.Switch SW 1 in the system is the little light switch of vehicle; Light-emitting diode D1, D2 are airbag aeration switch SW 2 and the background illumination light that turns to locking switch SW 4; Adopt paster type light emitting type BL-HZH32X-TRB; When opening lampet switch SW 1, D1 and D2 light, and chaufeur also can two switches of clear resolution at night.
