Technical Field

[0002] The present invention relates to the technical field of vehicles, and in particular to a vehicle. Background Art

[0003] In the related art, when the existing vehicle is waiting, the engine needs to be kept running to maintain the operation of the equipment, and the power demand of the equipment is very small, so the engine is always in a state close to idling, and the fuel consumption rate is extremely high. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0005] To this end, the present invention provides a vehicle.

[0006] In view of this, the present invention proposes a vehicle, comprising: a chassis, the chassis is provided with a fuel engine; a superstructure system, which is arranged on the chassis and includes equipment; a motor system, which is arranged on the chassis; and a power coupler, which is arranged on the chassis and is used to connect the fuel engine, the motor system and the equipment.

[0007] The vehicle provided by the present invention includes a chassis, a top system, a motor system and a power coupler. Specifically, the top system is arranged on the chassis, and the top system includes equipment, and the vehicle needs to provide power for the equipment. The chassis of the present invention is provided with a motor system and a power coupler. The power coupler can connect the fuel engine, the motor system and the equipment, and by controlling the state of the power coupler, the output power of the fuel engine or the motor system is controlled, thereby driving the equipment to operate. In the vehicle proposed by the present invention, the fuel engine and the motor system can both provide power for the equipment. Therefore, when the vehicle is not in a driving state, the engine does not need to work all the time to maintain the operation of the equipment, which reduces the energy consumption of the fuel engine and solves the problem of high fuel consumption rate of existing vehicles when waiting.

[0008] The vehicle according to the above technical solution of the present invention may also have the following additional technical features:

[0009] In one possible design, the vehicle further includes: a controller connected to the power coupler, the controller being used to obtain a working state of the vehicle and control the power coupler to close or open according to the working state.

[0010] In this design, the vehicle also includes a controller, which obtains the working state of the vehicle and controls the power coupler connected to the controller to close or disconnect according to the working state of the vehicle, thereby controlling the output power of the fuel engine or the motor system. Specifically, for example, when the vehicle is in a driving state, the controller can control the power coupler to connect the fuel engine, the motor system and the equipment. In this case, the fuel engine can output power to the motor system and the equipment while providing power for the vehicle to travel, and use the fuel engine to provide power for the equipment.

[0011] In a possible design, the vehicle also includes: a power take-off, the input end of the power take-off is connected to the fuel engine, the output end of the power take-off is connected to the power coupler, and the power take-off is used to transfer the power output of the fuel engine to the power coupler.

[0012] In this design, the vehicle also includes a power take-off, the input end of the power take-off is connected to the fuel engine, and the output end is connected to the power coupler, and the power take-off connects the fuel engine and the power coupler. When the fuel engine is running, the power take-off can obtain power from the fuel engine, and through its own conversion, transfer the power to the power coupler, and then output the power to the motor system and equipment according to the action of the power coupler.

[0013] Furthermore, the power take-off may be a full-power power take-off, which can obtain the maximum torque of the engine and has greater power, thereby providing greater driving force for vehicle travel and equipment operation.

[0014] In one possible design, the motor system includes: a motor connected to a power coupler; and a battery system connected to the motor; wherein, when the fuel engine outputs power to the motor system, the motor charges the battery system, and when the motor system outputs power to the device, the battery system supplies power to the motor.

[0015] In this design, the motor system includes a motor and a battery system, wherein the motor is connected to a power coupler, and the battery system is connected to the motor. When the fuel engine outputs power to the motor system, the power output by the fuel engine can drive the motor to operate, so that the motor charges the battery system. When the fuel engine is not working, the battery system can provide electrical energy to the motor, output power to the power coupler through the motor, and transmit it to the device via the power coupler, thereby driving the device to operate. The present invention can ensure the normal operation of the equipment whether the fuel motor is running or stopped through the charging and discharging of the battery system, without the need for the fuel motor to keep running all the time. In addition, when the fuel motor is running, the energy generated by the fuel motor can not only maintain the vehicle's driving, but the excess energy can be used to charge the battery system to avoid wasting energy from the fuel motor.

[0016] In one possible design, when the working state is a non-unloading state and a non-transporting state, the fuel engine is controlled to stop working and the power coupler is controlled to disconnect so that the battery system supplies power to the motor to drive the equipment to operate through the motor; when the working state is a unloading state or a transporting state, the fuel engine is controlled to work and the power coupler is controlled to close so that the fuel engine outputs power to the equipment and the motor system to drive the equipment to operate and drive the motor to charge the battery system.

[0017] In this design, the flow direction of power is controlled according to the working state of the vehicle. Specifically, when the working state of the vehicle is neither unloading nor transportation, the equipment does not need a lot of power to maintain operation, so the controller controls the fuel engine to stop working to avoid wasting resources. Further, the power coupler is controlled to be disconnected. At this time, the battery system can supply power to the motor to make the motor run, and the running motor drives the equipment to run. Only the electric energy stored in the battery system is used to maintain the operation of the equipment, which is conducive to saving energy; and when the working state of the vehicle is unloading or transportation, a large power is required to maintain the equipment unloading or vehicle driving. Therefore, the controller controls the fuel engine to work and uses the fuel engine to supply energy. Further, the power coupler is controlled to be closed. At this time, the fuel engine can output power to the equipment to drive the equipment to operate, and can also output power to the motor system, thereby driving the motor to generate electricity and charge the battery system, so that when the motor system is required to supply energy to the equipment, the battery system can output power to control the operation of the motor.

[0019] In this design, the motor system also includes a relay and a charging system. The relay is connected between the motor and the battery system to connect the motor and the electromagnetic system. Specifically, the relay can control the on and off of the circuit between the motor and the battery system. When it is detected that the battery system is fully charged, the relay controls the circuit to disconnect to prevent the motor from continuing to charge the battery system, causing the battery system to overcharge and affecting the service life of the battery system. The charging system is connected to the battery system. When charging the battery system, electric energy enters the battery system through the charging system. Specifically, the charging interface of the charging system is connected to the external power supply unit, and the electric energy enters the charging system through the charging interface. The power conversion is performed in the power change module of the charging system, and the converted electric energy is output to the battery system.

[0020] In a possible design, the device also includes: a mixing barrel; a hydraulic system, wherein an input end of the hydraulic system is connected to the power coupler, and an output end of the hydraulic system is connected to the mixing barrel, and the hydraulic system is used to drive the mixing barrel to rotate.

[0021] In this design, the equipment also includes a mixing barrel and a hydraulic system. The input end of the hydraulic system is connected to the power coupler, and the output end is connected to the mixing barrel. That is, the hydraulic system connects the power coupler and the mixing barrel. The power output by the fuel generator or the motor system is transmitted to the hydraulic system via the power coupler, and energy conversion is performed in the hydraulic system to drive the mixing barrel to rotate and mix cement, sand and gravel and other materials.

[0022] Furthermore, the hydraulic system may be a hydraulic transmission system, which utilizes liquid pressure to perform energy conversion, thereby simplifying the structure of the equipment, reducing manufacturing costs, and improving the reliability of the equipment.

[0023] In one possible design, the hydraulic system includes: a hydraulic pump, the input end of which is connected to the power coupler and is used to convert the power output of the power coupler into hydraulic pressure; a hydraulic motor, which is connected to the hydraulic pump and is used to generate torque output under the drive of hydraulic force; a reducer, the input end of the reducer is connected to the hydraulic motor, and the output end of the reducer is connected to the mixing barrel, and is used to drive the mixing barrel to rotate through the torque output of the hydraulic motor.

[0024] In this design, the hydraulic system includes a hydraulic pump, a hydraulic motor and a reducer. The input end of the hydraulic pump is connected to the power coupler, and the output end is connected to the hydraulic motor. The power transmitted by the power coupler is converted into hydraulic pressure and input into the hydraulic motor. The hydraulic motor converts the hydraulic pressure into mechanical energy, outputs torque and speed, and the mechanical energy output by the hydraulic motor is transmitted to the reducer connected to it. The speed is reduced under the action of the reducer, so that the mixing barrel rotates at a lower speed, saving energy while meeting the quality of the mixing materials.

[0025] In one possible design, the power coupling is an electromagnetic clutch or a one-way clutch.

[0026] In this design, the power coupler can be an electromagnetic clutch or a one-way clutch. The electromagnetic clutch is a friction clutch that generates a clamping force by electromagnetic force, has a quick and stable response, and a simple structure.
