Problems solved by technology

[0004] Most of the existing AGVs use motor-driven systems. The inventors found that the weight that motor-driven AGVs can carry is very limited. At the same time, there are disadvantages such as high requirements on the road surface, poor adaptability, and difficulty in realizing overload protection.

Abstract

The invention discloses a hydraulic system for hydraulically driving double steering wheels and a heavy-duty AGV, including a fuel tank, which supplies oil to a first hydraulic motor and a second hydraulic motor through an oil supply circuit, and the oil supply circuit is sequentially provided with hydraulic pumps , one-way valve, proportional valve, three-position four-way solenoid valve, the three-position four-way solenoid valve communicates with the first diverter-collector valve and the second diverter-collector valve, and the first diverter-collector valve communicates with the first hydraulic motor and the second hydraulic motor. The two hydraulic motors are connected, and the second diverter and flow valve is connected with the first hydraulic motor and the second hydraulic motor, so as to ensure the same flow rate of the two hydraulic motors.

Description

technical field [0001] The invention belongs to the technical field of hydraulic systems for AGVs, and in particular relates to a hydraulic system for hydraulically driving double steering wheels and a heavy-duty AGV. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] AGV refers to a transport vehicle equipped with automatic guidance devices such as electromagnetic or optical. It can adjust the corresponding transportation route in time with the adjustment of the production process without manual participation. AGV replaces manual transportation, which can effectively reduce the workload of the staff. It reduces labor intensity and improves work efficiency, so it has been widely used in manufacturing, electronics, logistics and other industries. [0004] Existing AGVs mostly use motor-driven systems. The inventors found that the weight that motor-dri...
