Abstract

The utility model relates to an automobile steering system, and discloses an energy-saving steering hydraulic power assisted system. The hydraulic power assisted system comprises a vane pump, a one-way valve, an energy accumulator, a steering control valve and a power assisted oil cylinder, wherein an overflow valve and a safety valve are arranged on the vane pump, the vane pump is in linkage with the steering control valve through the one-way valve, and the steering control valve is connected with the power assisted oil cylinder. The energy-saving steering hydraulic power assisted system is very reasonable in structural design, the energy accumulator is used for storing redundant energy of the system and timely releasing the energy when the system needs the energy, when an engine does not work or is in an idling state, the hydraulic system can still provide power for the power assisted cylinder, flow configuration of a steering oil pump is greatly reduced, and the energy-saving steering hydraulic power assisted system is high in practicability.

Description

Energy-conservation steering hydraulic force aid system
Technical field
The utility model relates to automobile steering system, has related in particular to a kind of energy-conservation steering hydraulic force aid system.
Background technology
The automobile that load-carrying is larger, front axle load is larger, and simple drives wheel steering by manpower, and it is obviously painstaking to drive.Therefore, on passenger vehicle and lorry, generally install steering hydraulic force aid system additional, when chaufeur steering direction dish, provide power-assisted, alleviated the driving intensity of chaufeur.
At present, conventional steering hydraulic force aid system, by being arranged on into driving engine blade pump directly to power steering oil supply cylinder.This system needs the configuration flow nargin of blade-type pump larger, and to meet the automobile demand that commutates fast, and in the normal driving process of automobile, the most of the time does not need quick commutation.Therefore, the too plentiful flow of blade-type pump has caused the huge waste of engine power, the automobile that load-carrying is larger, and the power steerig pump needing is larger, and energy dissipation is more serious.
Meanwhile, when driving engine is not worked or when idling mode, can not play power steering, this is abnormally dangerous when driving engine breaks down.Therefore, steering hydraulic power-assisted system exists obviously not enough at present.
Summary of the invention
The utility model, for the defect existing in prior art, provides a kind of reasonable in design, at driving engine, does not work or during in idling mode, still can be for servo cylinder provides power, and safe and reliable energy-conservation steering hydraulic force aid system.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Energy-conservation steering hydraulic force aid system, comprise blade-type pump, check valve, energy storage, steering control valve and power-assisted oil cylinder, on described blade-type pump, be provided with by pass valve and safety valve, described blade-type pump connects with steering control valve by check valve, and steering control valve is connected with power-assisted oil cylinder.
As preferably, described energy storage is connected between check valve and steering control valve.
The utility model, owing to having adopted above technical scheme, has significant technique effect:
The utility model structure design is very reasonable, energy storage is for the unnecessary energy of stocking system, when system needs, can release energy in time, hydraulic efficiency pressure system is not worked or during in idling mode at driving engine, still can greatly reduce the flow configuration of power steerig pump for servo cylinder provides power, there is very high practicality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing 1, with embodiment, the utility model is described in further detail:
embodiment 1
Energy-conservation steering hydraulic force aid system, as shown in Figure 1, comprise the blade-type pump 1, check valve 4, energy storage 5, steering control valve 6 and the power-assisted oil cylinder 7 that are arranged on driving engine, the similar Y type of steering control valve 6 principle of work three-position four-way valve, on described blade-type pump 1, be provided with by pass valve 2 and safety valve 3, described blade-type pump 1 connects with steering control valve 6 by check valve 4, and steering control valve 6 is connected with power-assisted oil cylinder 7, and described energy storage 5 is connected between check valve 4 and steering control valve 6.
When automobile is kept straight on, steering control valve 6 is closed, and the power fluid force feed that oil pump provides enters poultry energy device 5, stored energy, and when the hydraulic oil that poultry energy device 5 stores reaches certain pressure, safety valve 4 is opened, oil pump release.
When motor turning, steering control valve 6 can make oil circuit open, and the fluid that oil pump provides enters power-assisted oil cylinder 7 through rotary valve, and meanwhile, the hydraulic oil that poultry can device 5 interior storages also enters power-assisted oil cylinder 7, makes up oil pump flow deficiency, completes power-assisted.
In vehicle traveling process, oil pump is being worked always, and poultry energy device 5 is in deflector idle phase stored energy, in deflector work, release energy constantly, in this way, change simple dependence and strengthened the mode that oil pump flow meets deflector demand, reached energy-conservation object.At automotive engine in stopping or during idling mode, the hydraulic oil that is stored in advance energy storage still can provide power for turning to.
In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
