Abstract

The invention discloses a hydraulic steering system for an off-road mining dump truck. The hydraulic steering system comprises a hydraulic oil tank, an oil suction filter, an oil return filter, a constant-pressure variable pump, an oil pressure filter, a steering valve bank, an energy accumulator, a flow amplifier I, a flow amplifier II, a right steering cylinder, a left steering cylinder, a steering gear I, a steering gear II, a transfer mechanism and a direction control mechanism. Ports P and ports LS of the flow amplifier I and the flow amplifier II are respectively connected to ports P and ports LS of the steering gear I and the steering gear II, ports L and ports R of the flow amplifier I and the flow amplifier II are respectively connected to ports R and ports L of the steering gear I and the steering gear II, and input shafts of the steering gear I and the steering gear II are respectively connected with the direction control mechanism by the transfer mechanism. The hydraulic steering system has the advantages that output flow can be optimally doubled, and accordingly rotational speed requirements of the hydraulic steering system of the large-tonnage mining dump truck can be met.

Description

technical field [0001] The invention relates to a steering system, in particular to a hydraulic steering system of an off-highway mining dump truck, which belongs to the technical field of engineering machinery hydraulic control. Background technique [0002] Off-highway mining dump trucks (off-highway mining dump trucks) refer to a special load-carrying vehicle used for short-distance transportation to complete rock and earth stripping and ore transportation tasks on special roads such as open-pit mines or large civil construction sites. Widely used in various open-pit mines, hydropower projects, railway and highway construction projects and large-scale construction projects. Due to the characteristics of heavy load (currently up to 450t) and harsh working road conditions, the vehicle generally uses a hydraulic steering system to realize vehicle steering control. In view of the increasing load capacity of this type of vehicle, the current configuration of a single steering...
