Background technology
Low temperature liquid transport vehicle has a control box at the tank body rear portion, be furnished with all kinds of valves, pipeline etc. in the control box.Control box rear portion (vehicle tail) has a back door connection.When stopping loading and unloading liquid, must open the back door.The gate valve generally is installed on the car back door of carriage of dangerous goods vehicle, be mainly and prevent vehicle when loading and unloading the dangerous material goods because the place injustice causes slide car phenomenon, and can effectively prevent navigating mate in the situation of not closing the car back door, to start vehicle, avoid in the handling process vehicle accidental movement to break the loading and unloading pipeline and cause the situation such as leakage to occur.Vehicle can be achieved as follows parking braking function at present: the gate valve is installed on the car back door, be serially connected with between hand control valve (HCV) and the rapid release valve, when door is opened or become flexible, the gate valve exhaust, thereby pressure gas in the pipeline between hand control valve (HCV) and the rapid release valve is drained, cause the gas in the air tank spring cavity to be discharged via rapid release valve, form braking during standstill.
In the regular job, sometimes owing to reasons such as carelessness, cause the car back door not shut, in the vehicle high-speed operational process, the door accident is opened or is loosening, causes gate valve accident to open and causes emergency brake of vehicle, abnormally dangerous for the vehicle of normal enforcement like this, easily cause and blow out, the danger such as rollover, thus there is the major safety risks problem.
The utility model content
The utility model provides a kind of gate emergency brake system, in order to solving in the prior art vehicle in the high-speed cruising process, owing to gate valve accident is opened and caused emergency brake of vehicle to produce the problem of major safety risks.
Gate emergency brake system of the present utility model comprises: gate valve, electric brake system, rapid release valve, air tank; It is characterized in that, also comprise: double-way check valve, normally closed electromagnetic valve;
Described air tank, hand valve, gate valve, double-way check valve, the rapid release valve formation air brake piping that is linked in sequence;
Described double-way check valve is connected in described air tank by electromagnetic valve and consists of loading line; When this electromagnetic valve was opened, described air tank inflated to keep that the pressurized air in the pipeline is not discharged between two way solenoid valve and the rapid release valve to electromagnetic valve;
Described electric brake system is connected with described electromagnetic valve signal, in the speed of a motor vehicle during greater than a preset value to this electromagnetic valve transmitted signal to open this electromagnetic valve.
Described electromagnetic valve signal is connected on the diagnostics lines of described electric brake system, is transmitted control signal to this electromagnetic valve by the electronic control unit of described electric brake system.
The utility model is by adding double-way check valve and electromagnetic valve in the gate brake system, move the braking during standstill of system according to the speed control gate control of vehicle, so that vehicle is when running at high speed, if accident has been opened the gate valve, then vehicle brake condition can not occur, can avoid thus under high-speed travel state, occuring the moving accident that causes of gate control and occur, and when the speed of a motor vehicle is low, then can realize normally the gate braking during standstill of vehicle.

The specific embodiment
The exemplary embodiments that embodies the utility model feature ﹠ benefits will be described in detail in the following description.Be understood that the utility model can have at different embodiment various variations, its neither disengaging scope of the present utility model, and explanation wherein and appended accompanying drawing be when the usefulness that explain in itself, but not in order to limit the utility model.
Referring to shown in Figure 2, the utility model on the basis of existing gate brake system, the normally closed electromagnetic valve 2 that has increased a double-way check valve 1 and be attached thereto.
Describe below in conjunction with structure and the principle of accompanying drawing to this gate emergency brake system.In the present embodiment, air tank 3, hand valve 4, gate valve 5, double-way check valve 1, the rapid release valve 6 formation air brake piping that is linked in sequence; Double-way check valve 1 connects air tank 3 by electromagnetic valve 2, this electromagnetic valve 2 is normally closed solenoid valve, itself and EBS (Electrical Brake system, electric brake system) the control system signal connects, this electromagnetic valve 2 is connected on the diagnostics lines 7 of EBS system, and the EBS system inflates to double-way check valve 1 by the opening and closing control air tank 3 of control electromagnetic valve 2.Carried out in advance the parameter setting in the EBS system, be provided with a preset vehicle speed such as 15km/h, whether the EBS system, judges whether to the opening and closing of electromagnetic valve 2 transmitted signals with control electromagnetic valve 2 greater than this pre-set velocity according to the speed of a motor vehicle.
The principle of work of this gate brake system is as follows: when the speed of a motor vehicle is lower than this preset vehicle speed, this electromagnetic valve 2 keeps normally off, the gas circuit of air tank 3-electromagnetic valve 2-double-way check valve 1 is closed at this moment, air tank 3 is not inflated two way solenoid valve 2 ends, and the gas circuit conducting of air tank 3-hand valve 4-gate valve 5-double-way check valve 1-rapid release valve 6, then the gate control flowing mode of vehicle is same as the prior art at this moment, when open or looseness fault when causing gate valve 5 to be opened at the car back door, the 5 beginning exhausts of gate valve, thereby the pressurized air in hand valve 4-gate valve 5-double-way check valve 1-rapid release valve 6 these pipelines is discharged from, cause the gas in the two-chamber air chamber spring cavity to be discharged via rapid release valve 6, form the gate braking during standstill.
When the speed of a motor vehicle surpasses 15km/h, the ECU8(Electronic Control Unit of EBS system, electronic control unit) sends impulse singla, control electromagnetic valve 2 is opened, when electromagnetic valve 2 is in open mode, the 6 gas circuit conductings of air tank 3-electromagnetic valve 2-double-way check valve 1-rapid release valve, gas circuit is then closed between double-way check valve 1 and the gate valve 5, air tank 3 is to double-way check valve 1 this end inflation with rapid release valve 6, even gate valve 5 is opened exhaust at this moment, then also just drained pressurized air in the pipeline between hand control valve (HCV) 4 and the double-way check valve 1, and the pressurized air of pipeline can not be discharged between double-way check valve 1 and the rapid release valve 6, air tank 3 just can through rapid release valve 6 exhausts, just can not form the gate braking during standstill thus.
And when the speed of a motor vehicle by being down at a high speed pre-set velocity when following, the ECU8 of EBS system sends impulse singla, makes this electromagnetic valve 2 recover closure states, then when gate valve 5 is opened, still can form the gate braking during standstill.
In summary, the utility model is by adding double-way check valve and electromagnetic valve in the gate brake system, move the braking during standstill of system according to the speed control gate control of vehicle, so that vehicle is when running at high speed, if cause the gate valve to be opened accidentally having opened car door or failure condition, vehicle brake condition can not occur, can avoid thus occuring the moving accident that causes of gate control and occur under high-speed travel state, and when the speed of a motor vehicle is low, then can realize normally the braking during standstill of vehicle.
Those skilled in the art should recognize change and the retouching of doing in the situation that does not break away from the scope and spirit of the present utility model that the appended claim of the utility model discloses, all belong within the protection domain of claim of the present utility model.
