The working principle of the dual power tarpaulin driving system 100 in the present application is explained as follows:
1. the working principle of the vehicle in a non-driving state is as follows:
the controller 50 judges that the vehicle is in a non-running state, when a driver operates the tarpaulin to work, the motor 32 can not be electrified under the control of the controller 50, the first oil pump 34 does not work, the power takeoff 42 works and outputs the rotating speed to the double gear pump consisting of the second oil pump 44 and the third oil pump 48, and the second oil pump 44 outputs high-pressure oil to the electromagnetic directional valve 24 through the one-way valve and the filter 29. If the electromagnetic directional valve 24 is in the left or right position, the hydraulic motor 10 is rotated to operate the tarpaulin mechanism 120. If the electromagnetic directional valve 24 is in the neutral position, the high-pressure oil is unloaded, and the tarpaulin mechanism 120 does not operate.
2. The working principle of the vehicle in the running state is as follows:
the controller 50 judges that the vehicle is in a driving state, and when the driver operates the tarpaulin to be operated, the power take-off 42 is not operated, the motor 32 is powered, and the first oil pump 34 is operated under the control of the controller 50. The first oil pump 34 outputs high-pressure oil to the electromagnetic directional valve 24 via the check valve and the filter 29. If the electromagnetic directional valve 24 is in the left or right position, the hydraulic motor 10 is rotated to operate the tarpaulin mechanism 120. If the electromagnetic directional valve 24 is in the neutral position, the high-pressure oil is unloaded, and the tarpaulin mechanism 120 does not operate.
It should be noted that the controller 50 is set by the control logic such that the motor 32 and the power take-off 42 cannot be operated simultaneously.
As shown in fig. 2, the present invention further provides a vehicle, which includes a vehicle body 130, a lift cylinder 110, a tarpaulin mechanism 120, and a dual-power tarpaulin driving system 100 as in any one of the embodiments of the first aspect, wherein the dual-power tarpaulin driving system 100 is connected to the lift cylinder 110 and the lift cylinder 110.
In the above arrangement, the vehicle is integrated with the dual-power tarpaulin driving system 100, so that the vehicle has a function of automatically driving the tarpaulin to act, thereby enhancing the function of the vehicle and further meeting the multifunctional requirement of the vehicle.
The vehicle according to the second aspect of the present invention includes the dual-power tarpaulin driving system 100 according to any one of the embodiments of the first aspect, so that all the advantages of any one of the embodiments are provided, and details are not repeated herein.
The dual-power tarpaulin driving system 100 and the vehicle in the application have the following advantages:
1. the invention has the advantages of both full hydraulic power drive and pure electric drive of the tarpaulin mechanism 120.
2. When the second power assembly 40 is driven in a full hydraulic mode, the tarpaulin mechanism 120 is large in action force and high in speed, when the muck is slightly higher than the compartment, the tarpaulin mechanism 120 large in action force and high in speed can push the muck to be flat, and a driver is prevented from manually leveling the muck again.
3. When the first power assembly 30 is driven by the motor, the tarpaulin can be operated to move no matter the vehicle is running or stopped, the problem that a driver needs to stop after loading and unloading soil and waits for the tarpaulin to be opened or closed in place and then runs is avoided, and the working efficiency is improved.
From the above description, it can be seen that the controller 50 can select the first power assembly 30 or the second power assembly 40 according to different working conditions to provide power for the hydraulic motor 10, so as to meet the requirements of the driver on the tarpaulin driving system under different working conditions.
