The specific working mode and principle of the parking system in above-described embodiment is further illustrated below.Due to this field skill
Art personnel understand the basic functional principle of the utility model parking system in combination with attached drawing, therefore following explanations focuses primarily upon
Working method and principle that the utility model realizes its particular technology purpose or effect can be embodied.
Parking brake module 16 only includes mechanical and electromechanical component, these components be control main vehicle parking braking it is required
's.In order to discharge parking braking, the spring brake chamber 4 of vehicle parking mechanism must be full of compressed air until certain journey
Degree could push piston 2 to spring 1 and brake bar 3 is driven to move back, to eliminate the brake force on wheel.
In order to discharge parking braking, electronic control unit 7 drives the first solenoid valve 8 and second solenoid valve 19, keeps compression empty
Gas flows to the control chamber 11 of relay valve 14 by a solenoid valve high position from the first gas source interface 9.Relay valve 14 is by compressed air and its
The pressure of control room 11 is directly proportional, is input to cylinder chamber 4 from the first gas source interface 9.At this point, if being connected to trailer braking protection valve mechanism 5,
Then the air pressure of the control channel 24 of trailer braking protection valve mechanism 5 is identical as the air pressure of cylinder chamber 4.In addition, passing through first pressure sensor
The delivery outlet pressure rating of 18 measurements can calculate the air pressure of control chamber 11.
When pressure has reached enough stress levels, the power-off of the first solenoid valve 8 allows for compressed air to flow into control
Chamber 13, thus the switching pneumatic bistable state two-position three-way valve of the first Pneumatic valve 12(), while second solenoid valve 19 powers off, at this time first
Pneumatic valve 12 is directly connected to the control chamber 11 of the first gas source interface 9 and relay valve.Under this state, even if power fails, parking
Brake release state is also that can maintain.
In order to be switched to parking braking state from release conditions, electronic control unit 7 starts second solenoid valve 19 first, will
Compressed air cutting between first Pneumatic valve 12 and control chamber 11.Later, start third solenoid valve 20, control chamber 11 is connected
It is released stress to second row air valve 21, and in this way.In this process, the 6th solenoid valve 22 of trailer module 15 can also
To be activated, and then third exhaust valve 23 is connected, and the evacuation time of system is reduced.When the pressure of control chamber 11 is reduced to the first gas
When controlling the closing pressure of valve 12, which is also connected to first row air valve 25 for control chamber 11 simultaneously；Due to the work of spring 26
With making the first Pneumatic valve 12 be maintained at this position, even if losing electric power, also ensure that safe parking braking state.
Any desired pressure rating is arrived in order to the control chamber 11 of adjusting relay valve 14, second solenoid valve 19 can be used
Control is adjusted with third solenoid valve 20.In order to increase pressure, second solenoid valve 19 and third solenoid valve 20 are closed.For
Reduction pressure, second solenoid valve 19 and third solenoid valve 20 are activated.In order to keep the stress level of earlier set value, the
Two solenoid valves 19 are activated, and third solenoid valve 20 is closed.In this way, the pressure of the control channel 24 of trailer module 15
Power is also controlled by, and with the stress level having the same of the output interface of relay valve 14 17.
In both cases, the air pressure of the control channel 24 of trailer module 15 should be independently of the air pressure of relay valve control chamber 11
It is controlled.The first situation is trailer test function, and when the parking braking of tractor is activated, the brake on trailer is necessary
It is released.It means that control chamber 11 is completely filled with compressed air, the control channel 24 in trailer module 15 is by possible maximum
Stress level fills up.Another situation is that so-called trailer braking protection valve or resilient function.In this case, relay valve 11
Control room is filled possible maximum pressure levels, is independently adjustable in the pressure of the control channel 24 of trailer module 15 any
Possible values.
In order to realize trailer test function of the parking braking system under parked state, the control of electronic control unit 7 the 4th
First gas source interface 9 of the connection of solenoid valve 27 and control channel 24, at the same the 5th solenoid valve 28 for controlling trailer module 15 be isolated it is defeated
Outgoing interface 17 and control channel 24, to realize the independent control of 24 air pressure of control channel.
To realize that individual trailer braking protection valve, electronic control unit 7 drive the 5th solenoid valve 28 in trailer module 15 first
The pressure of relay valve output interface 17 is separated, the 6th solenoid valve 22 is driven later, control channel 24 is made to be connected to third exhaust valve
23 are exhausted.Later, in order to independently realize the pressure increase of control channel 24, the 5th solenoid valve 28 is activated, the 6th electromagnetism
Valve 22 is powered down, while the 4th solenoid valve 27 is activated, so that the first gas source interface 9 is connected to control channel 24, makes its pressure
Power increases.
In order to control pipeline 24 in keep any stress level, be allowed to the pressure independently of relay valve output interface 17,
It can be closed by five solenoid valves 28, the 4th solenoid valve 27 and with the 6th solenoid valve 22.
When parking braking system is activated, extreme force is generated in braking system in order to prevent, second can also be passed through
29 compressed gas supplying of gas source interface, and control chamber 11 is entered by the first input interface 10a of double-way check valve 10, thus
Avoid/prevent the generation of extreme force.
In order to prevent in the case where the first gas source interface 9 breaks down caused parking braking fortuitous event, system
In be provided with check valve 30, it only allows the air-flow in a direction to enter system, and prevents airflow reflux to the first gas source interface
9。
A possibility that in order to ensure parking or release parking braking, even if electric system is unavailable, system also has a company
It is connected to the third gas source interface 32 of relay valve control chamber 11.This interface is in close state under normal conditions；In necessary situation
Under, if importing compressed gas from this gas source interface applies pressure, system will be switched to release conditions.
On the other hand, it in order to meet commercial demand, easily and flexibly configures and installs, in the parking system of the utility model
Associated components are divided into three modules, can meet the needs of main vehicle in the case where no trailer without increasing extra charge.
Specifically, the electronic control unit 7 of the parking system of the utility model, parking brake module 16 and trailer module 15 can be
