WORKING VEHICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18533267 titled 'WORKING VEHICLE
The abstract describes a working vehicle with two hydraulic pumps, load sensing control, control valves for hydraulic actuators, a power shift valve, and a power steering controller.
- First hydraulic pump with load sensing control
- Second hydraulic pump for power shift valve and power steering controller
- Control valves for working-machine-related hydraulic actuators
- Power shift valve for traveling-power-transmission-related hydraulic actuator
- Power steering controller for steering-related hydraulic actuator
Potential Applications: - Construction equipment - Agricultural machinery - Industrial vehicles
Problems Solved: - Efficient control of hydraulic systems - Precise control of hydraulic actuators - Improved performance in working vehicles
Benefits: - Enhanced productivity - Increased efficiency - Better maneuverability
Commercial Applications: Title: "Hydraulic System for Working Vehicles" This technology can be used in various commercial applications such as construction, agriculture, and industrial sectors. It can improve the performance and efficiency of working vehicles, leading to cost savings and increased productivity.
Questions about Hydraulic Systems for Working Vehicles: 1. How does load sensing control improve the performance of hydraulic systems in working vehicles? Load sensing control adjusts the delivery flow rate of the hydraulic pump based on the load requirements, ensuring optimal performance and efficiency.
2. What are the advantages of having separate hydraulic systems for working-machine-related control valves and power shift valve/power steering controller? Separate hydraulic systems allow for independent control and operation of different functions in the working vehicle, enhancing overall performance and flexibility.
Original Abstract Submitted
A working vehicle includes a first hydraulic pump (e.g., a variable displacement pump) with a delivery flow rate controlled by load sensing control, a second hydraulic pump (e.g., a fixed displacement pump), at least one working-machine-related control valve to control at least one working-machine-related hydraulic actuator, a power shift valve to control at least one traveling-power-transmission-related hydraulic actuator, and a power steering controller to control a steering-related hydraulic actuator. The at least one working-machine-related control valve is provided in a first hydraulic system supplied with hydraulic fluid by the first hydraulic pump, and at least one of the power shift valve or the power steering controller is provided in a second hydraulic system supplied with hydraulic fluid by the second hydraulic pump.
