Detailed Description
The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and the detailed description, so as to clearly and completely describe the technical solution of the present invention. It is to be understood that the described embodiments are merely exemplary of the utility model, and not restrictive of the full scope of the utility model. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example (b):
as shown in fig. 1-3, an air circuit combined type irreversible full-time pneumatic parking system comprises an air pump 7, an air storage tank 1, a pedal brake valve 4, a hand brake mechanism 5 and a brake pump 2, wherein the air pump 7 is communicated with the air storage tank 1 through an air circuit, an output air circuit of the air storage tank 1 is respectively communicated with the brake pump 2 and a gearbox 3, the pedal brake valve 4 is installed on a communication air circuit between the air storage tank 1 and the gearbox 3, the hand brake mechanism 5 is arranged between the air storage tank 1 and the brake pump 2, and a check valve 52 is arranged between the hand brake mechanism 5 and the air storage tank 1.
The air pump 7 is used for providing air with preset pressure, and the air reaches the air storage tank 1 through the air passage to store sufficient air for the working use of the system.
The hand brake mechanism 5 comprises a hand brake valve 51 and a shuttle valve 53, the shuttle valve 53 is provided with double air outlet channels, one air channel of the shuttle valve 53 is communicated with the brake pump 2, and the other air channel of the shuttle valve 53 is communicated with the hand brake valve 51.
Through the technical scheme, when the pedal valve is stepped on, the air storage tank 1 outputs air with preset pressure to open the shuttle valve 53 to act on the brake pump 2 and directly reach the four-wheel brake caliper 6, so that the four-wheel brake caliper 6 is in a cut-off state, the braking effect is achieved, meanwhile, the purpose that the pedal plate directly controls the gearbox 3 is achieved by passing through the pedal plate in front of the gearbox 3, the gearbox 3 is directly locked at the moment, the mechanical traveling system is completely statically braked, and the machine stops. When the hand brake valve 51 is braked, air acts on the shuttle valve 53 through the check valve 52 and the hand brake valve 51 and then acts on the brake pump 2 to reach the four-wheel brake caliper 6, thereby performing a braking function.
When the pedal is released, the output pressure of the brake pump 2 disappears, the gas is discharged, the gas of the four-wheel brake caliper 6 and the gas of the gearbox 3 are simultaneously discharged through the pedal valve, and the gearbox 3 is unlocked so that the machine can walk. When the hand brake valve 51 is released, the air which also acts on the four-wheel brake caliper 6 flows back to the exhaust port of the hand brake valve 51, the air is exhausted, and the machine can walk to complete a system cycle. The system greatly improves the parking stability, avoids the phenomenon of vehicle sliding, and greatly reduces the production cost and the oil consumption.
The hand brake mechanism 5 in the system is a key part and is different from the conventional and existing parts of any machine type, and the hand brake mechanism can still exert the complete parking brake function even if the air storage tank 1 loses pressure or leaks air through the cooperation of the one-way valve 52 and the shuttle valve 53. The check valve 52 and the shuttle valve 53 are designed to be non-return, so that the gas flowing from the gas tank 1 to the hand brake valve 51 cannot return when encountering the check valve 52 and stays in the gas path between the check valve 52 and the hand brake valve 51, and the shuttle valve 53 has the same function.
The gas storage tank 1 is provided with a safety valve 8 and an unloading valve 9. The output end of the air pump 7 is connected with the input end of the unloading valve 9.
Through the technical scheme, the safety valve 8 and the unloading valve 9 arranged on the gas storage tank 1 in the system can effectively protect the gas storage tank 1 and a gas circuit, when the power part continuously charges gas into the gas storage tank 1, certain pressure and capacity are achieved, and the unloading valve 9 can automatically discharge redundant gas to achieve the protection effect.
One end of the brake pump 2 far away from the shuttle valve 53 is directly connected with a four-wheel brake caliper 6, and two brake pumps 2 and two four-wheel brake calipers 6 are arranged. The synchronous braking of the front wheel and the rear wheel can be realized by arranging the two four-wheel brake calipers 6, so that the parking stability can be greatly improved, and the phenomenon of vehicle sliding is effectively avoided.
The air storage tank 1 is provided with two air path outlet ports which are connected through air pipes, and the two air pipes are respectively communicated with the brake pump 2 and the gearbox 3. The double-circuit air pressure control can be realized by arranging the brake pump 2, namely, the brake pump can respectively convey brake air to the two four-wheel brake calipers 6 to play a braking effect.
