Abstract

The invention discloses a dynamic load sensing all-hydraulic steering system of a street sweeper. The system comprises an oil tank, an oil pump, a pressure compensation priority valve, a pressure compensation all-hydraulic steering gear, a steering wheel and a steering cylinder, wherein the steering cylinder is arranged between a front frame and a rear frame which are hinged to each other, the front frame and the rear frame can be driven to rotate so as to perform the steering action, the pressure compensation priority valve is provided with a P1 port, a CF port, an EF port, an LS1 port and a T1 port, and the pressure compensation all-hydraulic steering gear is provided with a P2 port, an L port, an R port, an LS2 port and a T2 port. The system has the advantages of being flexible in steering performance, capable of realizing small-size installation, capable of reducing power loss, high in adaptability to cold weather, simple in operation, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of sweeping vehicles, in particular to a hydraulic steering system of the sweeping vehicle. Background technique [0002] The floor sweeper is an integrated garbage sweeper that combines sweeping and vacuuming. It has the advantages of high work efficiency, low cleaning cost, good cleaning effect, high safety performance, and high economic return rate. It has been widely used on roads in various cities cleaning work. [0003] At present, small diesel sweepers do not have a complete hydraulic steering system. Existing sweeping vehicles generally refer to relatively mature hydraulic steering system solutions such as tractors, forklifts, and loaders. However, there are common problems such as large volume, rough system, poor steering flexibility, abnormal noise when working in cold weather, and large power loss. [0004] Therefore, how to improve the existing hydraulic steering system of the sweeping vehicle...
