Further, the parking brake control device further comprises a reservoir 18, and a pipeline between the first check valve 4 and the pressure reducing valve 5 is communicated with the reservoir 18 through a fourth port.
The schematic structure diagram of the piston valve 9 is shown in fig. 2, wherein the end A4 is a pre-control end of the piston valve 9, the end A3 is an inlet end of the piston valve 9, the end A2 is an outlet end of the piston valve 9, and the end A1 is only open to the atmosphere; the schematic structure diagram of the electromagnetic valve 10 is shown in fig. 3, wherein the end B4 is a pilot port of the electromagnetic valve 10, the end B1 is a first pilot port of the electromagnetic valve 10, the end B2 is a second pilot port of the electromagnetic valve 10, the end B3 is a third pilot port of the electromagnetic valve 10, as shown in fig. 1, the pre-control end (end A4) of the piston valve 9 is connected with the brake pipe 2, the inlet end (end A3) of the piston valve 9 is communicated with an input pipeline (i.e., a pipeline between the pressure reducing valve 5 and the pulse valve 6) of the pulse valve 6, the outlet end of the first check valve 4 is communicated with the pilot port (end B4) of the electromagnetic valve 10, the outlet end (end A2) of the piston valve 9 is communicated with the first pilot port (end B1) of the electromagnetic valve 10, the second pilot port (end B2) of the electromagnetic valve 10 is communicated with an output pipeline (i.e., a pipeline between the pulse valve 6 and the two-way check valve 7) of the pulse valve 6, and the third pilot port (end B3) of the electromagnetic valve 10 is communicated with the first two-way check valve 7.
The working principle of the piston valve 9 is as follows: when the end A4 of the pre-control end has no pressure, the end A3 is cut off, and the end A2 is communicated with the end A1; when the pre-control end A4 has pressure, the end A2 is communicated with the end A3, and the end A1 is only opened to the atmosphere.
The operating principle of the solenoid valve 10 is as follows: when the electromagnetic valve is powered off, the end B1 is communicated with the end B3, and the end B2 is only communicated with the atmosphere; when the electromagnetic valve is electrified and the pilot port B4 is used for introducing pressure air, the B2 end is communicated with the B3 end, the B1 end is not communicated with the B3 end, and the B1 port is cut off.
When the vehicle is in the rescue mode, the working states of the piston valve 9 and the electromagnetic valve 10 are as follows: the rescue vehicle is filled with compressed air into the brake pipe 2 of the fault vehicle, the compressed air further enters the main air pipe 1, and the pre-control end (A4 end) of the piston valve 9 is subjected to air pressure in the brake pipe 2 through a fifth port, so that the inlet end (A3 end) and the outlet end (A2 end) of the piston valve 9 are communicated; the solenoid valve 10 is deenergized, so the first pilot port (B1 end) of the solenoid valve 10 communicates with the third pilot port (B3 end). Based on the above, the brake pipe 2, the main air pipe 1, the first port, the first check valve 4, the pressure reducing valve 5, the piston valve 9, the electromagnetic valve 10, the two-way check valve 7, the plug valve 8, the second port and the parking brake cylinder 3 form an air path for realizing remote relief in a rescue mode. The brake pipe 2 is connected with a brake pipe of a rescue vehicle, the rescue vehicle is used for introducing pressure air into the brake pipe of a fault vehicle, and finally the pressure air enters the parking brake cylinder 3, so that the parking brake in the rescue mode/fault mode is relieved remotely.
The parking brake cylinder is a spring applying structure, and if no compressed air is supplied to the parking brake cylinder, the spring inside the parking brake cylinder automatically applies a parking brake force. Under normal conditions, the vehicle needs to be relieved of park braking while traveling. At the moment, the electromagnet for parking and relieving the pulse valve is electrified, the air pressure of the main air pipe can reach the parking brake cylinder through the following path, the spring force of the parking brake cylinder is overcome, and the release of parking brake is realized. When the vehicle is in a parking brake release mode, the brake pipe 2 provides air pressure to the pre-control end (A4 end) of the piston valve 9, so that the inlet end (A3 end) of the piston valve 9 is communicated with the outlet end (A2 end), and the electromagnetic valve 10 is in a power-on state in the parking brake release mode, the second guide port (B2 end) of the electromagnetic valve 10 is communicated with the third guide port (B3 end), and then the main air pipe 1, the first port, the first check valve 4, the pressure reducing valve 5, the pulse valve 6, the electromagnetic valve 10, the two-way check valve 7, the plug door 8, the second port and the parking brake cylinder 3 form an air path for releasing parking brake.
When the vehicle needs to apply parking brake, the parking brake electromagnet of the pulse valve can be electrified, compressed air in the parking brake cylinder can be exhausted through the exhaust hole of the pulse valve, and the parking brake can be applied. When the vehicle is in a parking brake applying mode, the parking applying electromagnet of the pulse valve 6 is powered on, the electromagnetic valve 10 is powered on, the second guide port (B2 end) of the electromagnetic valve 10 is communicated with the third guide port (B3 end), and then the air exhaust hole of the parking brake cylinder 3, the second port, the plug valve 8, the two-way check valve 7, the electromagnetic valve 10 and the pulse valve 6 forms an air path for realizing the application of the parking brake, and in the mode, the air in the parking brake cylinder 3 is exhausted through the air exhaust hole of the pulse valve 6.
In addition to the parking brake cylinder 3, the vehicle comprises a service brake cylinder 13 and a service brake pressure input in communication with the service brake cylinder 13, to which the second input line of the two-way check valve 7 of the parking brake control device is in communication, see fig. 1; when the vehicle applies service braking, the service braking pressure is led to the third port of the parking braking control unit while being led to the service braking cylinder, and reaches the right end (in the figure) of the two-way check valve, and compared with the pressure air entering the left end of the two-way check valve, the pressure reaches the spring parking braking cylinder through the two-way check valve so as to ensure that the parking braking is completely relieved, meanwhile, the service braking and the parking braking are simultaneously applied to the braking clamp, further, the damage of the braking clamp caused by overlarge braking force is avoided, and the locking of an axle caused by overlarge braking force applied by one axle is also avoided. When the vehicle is in service brake application mode, the service brake pressure input → port three → bi-directional check valve 7 → plug 8 → port two → parking brake cylinder 3 forms an air path that ensures parking brake relief in service brake application conditions. A part of the air flow fed in at the service brake pressure input follows the path described above to the parking brake cylinder 3 and another part directly to the service brake cylinder 13.
In a preferred embodiment, a second throttle 11 is also provided in the line between the pressure-reducing valve 5 and the pulse valve 6, and a third throttle 12 is also provided in the line between the service brake pressure input and the two-way check valve 7. The first throttle valve 19, the second throttle valve 11 and the third throttle valve 12 all function as saving control air flow.
In another preferred embodiment, a pressure sensor 14 and a first test joint 15 are also arranged on the pipeline between the two-way check valve 7 and the plug valve 8; further, a second test joint 16 and a pressure switch 17 are also arranged on the pipeline between the pressure sensor 14 and the plug door 8. The pressure sensor 14 is used for detecting the pressure value of the outlet end of the two-way check valve 7, the first test joint 15 and the second test joint 16 are both used for performing pressure test, and the pressure switch 17 is used for monitoring the parking brake air pressure.
The rescue vehicle is connected with the vehicle to be rescued through a brake pipe, the pressure of the brake pipe of the rescue vehicle can reach the inside of the brake pipe of the vehicle to be rescued, and the main air pipe of the vehicle to be rescued is charged with air through the first throttle valve 19 and the second check valve 20 through the second check valve 20. At this time, the control end of the piston valve 9 has pressure, and the solenoid valve 10 is in the power-off position. The pressure of the main air pipe reaches the parking brake cylinder through the piston valve 9 and the electromagnetic valve 10, so that the remote relief of the parking brake of the rescued vehicle is realized. According to the parking brake control device, when the fault vehicle is in the rescue mode, the rescue vehicle charges air to the brake pipe of the fault vehicle through the brake pipe, and reaches the parking brake cylinder through the piston valve and the electromagnetic valve, so that remote release of parking brake of the vehicle in the rescue mode is realized, and the line occupying time of the fault vehicle is greatly shortened. According to the road, long as the brake pipe of the rescue vehicle is communicated with the vehicle to be rescued, the remote release of the parking brake of the vehicle to be rescued can be realized without other manual operation, the operation flow of a vehicle driver is simplified, the line occupying time of a fault vehicle is greatly shortened, and the normal operation of the vehicle on the same line is ensured.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
