Specific implementation mode
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and cannot be construed to the utility model
Limitation.
The utility model provides a kind of trailer auxiliary braking control system on the basis of existing trailer brake system
Embodiment, as shown in Fig. 2, including headstock foot valve and trailer braking protection valve gas chamber while further comprise：Controller, trailer braking protection valve are auxiliary
Help gas chamber, the electric control valve being connect with trailer braking protection valve auxiliary tank gas circuit, the brake switch for being installed on headstock foot valve and installation
Gas circuit is indicated with solid line in the pressure sensor of trailer braking protection valve gas chamber, figure, is represented by dotted lines electrical connection.
Controller can select the control units such as entire car controller, and effect in the present invention is to receive system
After the closure signal of dynamic switch, after that is to say that headstock foot valve is stepped on by driver, which detects what pressure sensor was sent
The air pressure signal of trailer braking protection valve gas chamber, in this, as trailer braking protection valve gas chamber is judged, whether there is or not the foundations of normal work, here it may be said that
Bright, air pressure signal can directly reflect the real-time air pressure of trailer braking protection valve gas chamber, can also be sentenced according to preset inflationtime
Fixing time, whether there is or not reach scheduled standard for the air pressure of trailer braking protection valve gas chamber after reaching, it is also contemplated that combines the brake chamber of headstock
Air pressure determine trailer braking protection valve requirement whether mentioned earlier jointly --- braked prior to headstock, those skilled in the art can root
According to conventional design logic, select it is any with air pressure signal judgement braking whether effective control program, the utility model pair
This is not limited；It connects above, controller is according to air pressure signal and then triggers electric control valve and is opened and closed, and trailer braking protection valve is controlled with this
Auxiliary tank executes braking maneuver can also be arranged relay from automatically controlled consideration in this system, specifically, controller can lead to
Trigger relay action, control electric control valve opening and closing are crossed, and the power supply of electric control valve then can come from accumulator.
About the air source of trailer braking protection valve auxiliary tank, its type selecting is various in practical operation, for example, from save cost
Consider, gas receiver identical with trailer braking protection valve gas chamber may be used；It is of course also possible to add one independently of trailer system for it
Take offence room air source auxiliary gas receiver, by this redundancy be arranged to promote reliability.
For above-described embodiment, it should be noted that, in another preferred embodiment of the utility model, trailer braking protection valve is auxiliary
Help gas chamber that can use a larger two-chamber gas chamber with trailer braking protection valve gas chamber together as one and realize two kinds of gas chambers and deposit,
Arrangement space can be saved with this.
Based on above-described embodiment, the utility model also further contemplate early warning after original trailer braking protection valve fails and
Other safety measures, such as can also include the combination instrument that is electrically connected with the controller in the present system, can by word,
The forms such as figure or light indicate the operating status of current auxiliary braking；In addition, can also include and control in this system
The control unit of engine of device electrical connection；Controller, can also be to starting after trailer braking protection valve auxiliary tank executes braking maneuver
Machine control unit sends limited torque instruction, it is therefore an objective to which reducing speed ensures safety.It should be noted that combination instrument and engine
