However, this flow distribution method is relatively fixed, and because this flow distribution method needs to connect the oil return line of the steering oil circuit to the travel oil circuit, the pressure superposition phenomenon will occur in the travel oil circuit and the steering oil circuit
On the one hand, this phenomenon will lead to a large energy loss in the steering action of the vehicle during walking; turn to

The invention provides a traveling and steering hydraulic system for a vehicle, and an aerial work platform. The traveling and steering hydraulic system comprises a hydraulic pump, an executing component and a control valve group; the hydraulic pump is configured to provide hydraulic oil for the traveling and steering hydraulic system; the executing component comprises a traveling motor used for enabling the vehicle to execute the traveling action and a steering oil cylinder used for enabling the vehicle to execute the steering action, and the traveling motor and the steering oil cylinder aremutually connected in parallel; and the control valve group comprises a hydraulic control valve arranged between the hydraulic pump and the executing component, a feedback oil way is formed between the hydraulic control valve and the executing component and configured to feed back the load of the steering oil cylinder, and the hydraulic control valve is configured to adjust the working state of the hydraulic control valve according to the pressure of the feedback oil way to distribute the flow of the hydraulic oil to the traveling motor and the steering oil cylinder. The aerial work platform comprises the traveling and steering hydraulic system. According to the traveling and steering hydraulic system for the vehicle, and the aerial work platform, the flow distribution situation and the pressure superposition phenomenon of the traveling and steering hydraulic system can be improved, and energy saving and adaption to complex working conditions of the vehicle are facilitated.
Description
technical field [0001] The present disclosure relates to the field of hydraulic technology, in particular to a walking steering hydraulic system and an aerial work platform. Background technique [0002] The walking steering system is one of the important components of construction vehicles. The travel steering system needs to have good handling and safety to make the whole vehicle running process flexible and efficient. [0003] The traveling and steering hydraulic system of the existing scissor-type aerial work platform mainly distributes the flow of the traveling oil circuit and the steering oil circuit through the pressure compensation flow regulating valve. However, this flow distribution method is relatively fixed, and because this flow distribution method needs to connect the oil return line of the steering oil circuit to the travel oil circuit, the pressure superposition phenomenon will occur in the travel oil circuit and the steering oil circuit. On the one hand, ...
