Abstract
The utility model discloses a hydraulic steering system, which consists of an oil cylinder, an energy accumulator, a pressure switch, a load sensitive proportional valve group, a liquid filling valve, a hydraulic pump and an oil tank, wherein the energy accumulator is connected with the liquid filling valve through one circuit, the liquid filling valve is connected with a hydraulic pump through one circuit and is connected with the oil cylinder through another circuit, the oil tank is connected with the oil cylinder through one circuit and is connected with the hydraulic pump through another circuit, and the load sensitive proportional valve group is connected onto a circuit arranged between the energy accumulator and the liquid filling valve through circuits. The hydraulic steering system has the advantages that when the full-wheel steering is needed, the follow-up with the towing vehicle steering is realized, and only automatic centering is needed during the towing vehicle steering.
Description
Technical field
The utility model belongs to mechanical electric control field, relates in particular to a kind of hydrostatic steering system.
Background technology
Electric powered steering is directly to provide power-assisted with electrical motor, the power steering system that power-assisted size is controlled by ECU (Electrical Control Unit) (ECU).Torque sensor and steering shaft link together, and in the time that steering shaft rotates, working sensor, passes to ECU by signal, and ECU determines the power-assisted effect of electrical motor according to the speed of a motor vehicle, with guarantee automobile drive when the low speed light, reliable and stable when high speed.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, can realize the hydrostatic steering system of the automatic distribution of flow when a kind of follow-up steering is provided.
The utility model takes following technical scheme to realize: a kind of hydrostatic steering system, it is by oil cylinder, energy storage, pressure switch, load-sensitive apportioning valve group, prefill valve, Hydraulic Pump and fuel tank composition, described energy storage is connected with prefill valve by a circuit, described prefill valve is connected with Hydraulic Pump by a circuit, described prefill valve is connected with oil cylinder by another circuit, described fuel tank is connected with oil cylinder by a circuit, be connected with Hydraulic Pump by another circuit, described load-sensitive apportioning valve group is connected on the circuit between energy storage and prefill valve by circuit.
The utlity model has in sum following beneficial effect: this system can be in the time of needs four-wheel steering and tractor truck turn to realize servo-actuated, automatic centering while only needing tractor truck to turn to.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
