Description
Technical field
The utility model belongs to Automotive Steering Technology field, particularly relates to a kind of emergency double loop power steering system.
Background technology
Automobile steering system formula is owing to changing or keeping the specialized agency of vehicle traveling direction, work is make automobile can in time change its travel direction according to the Control requirements of chaufeur in the process of moving, and when the accidental impact being subject to transmitting on road surface and automobile unexpectedly depart from travel direction, can coordinate with driving system and jointly keep automobile to continue stable traveling.Therefore, the performance of steering swivel system directly affects road-holding property and the safety of automobile.Automobile steering system is divided into two large classes: manual steering system is unified power steering system, and the steering swivel system handled by chaufeur hand-power is completely called mechanical steering system; The steering swivel system handled by power is called power steering system; Power steering system can be divided into again hydraulic power steering system and electric boosted power steering system, steering swivel system is primarily of steering control mechanism, deflector, steering gear composition, and steering control mechanism is primarily of compositions such as steering handwheel, steering shaft, steering columns.The rotation of steering handwheel is become the swing of pitman arm or the straight reciprocating motion of rack shaft by deflector, and to the mechanism that steering force amplifies.Deflector is generally fixed on automobile chassis frame or vehicle body, and steering force is by generally also changing transmission direction after deflector.The force and motion that deflector exports is passed to wheel (steering swivel) by steering gear, and makes left and right wheels carry out the mechanism deflected by certain relation.Traditional single loop hydraulic power steering system can not provide servo-steering, main steering pump to lose efficacy when mainly there is engine off can not provide servo-steering, idling steering flow little, the shortcomings such as idling hard steering.
Utility model content
in order to solve existing the problems referred to above, the utility model provides a kind of emergency double loop power steering system, traditional single loop power steering system can be replaced to solve the problem that can not turn to when engine off or steering blade pump break down, improve vehicle safety.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
A kind of emergency double loop power steering system, comprises intercommunication Fuel Tanking Unit, steering blade pump, jury pump, guard valve, deflector and follower; Guard valve, deflector, steering blade pump and jury pump are all connected with intercommunication Fuel Tanking Unit, and guard valve is also connected with steering blade pump, jury pump and deflector, and deflector is connected with follower.
Further, described intercommunication Fuel Tanking Unit is made up of the first oil tank and the second oil tank, and first, second oil tank is connected by an oil pipe, and the first oil tank is connected with deflector and deflector blade-type pump, and the second oil tank is connected with guard valve and jury pump.
In order to provide warning when driving engine or steering blade pump break down, described guard valve is also connected with a stand by lamp.
Further, described stand by lamp is connected on the reducing valve in guard valve.
The beneficial effect that the utility model reaches is: the utility model by the vehicle wheel rotation of vehicle as power, make when any fault appears in driving engine and main steering swivel system, can ensure that traveling vehicle possesses steering capability, at utmost improve the safety performance of vehicle.The utility model adopts intercommunication Fuel Tanking Unit mode of knowing clearly, can not only prevent also possessing good thermal diffusivity because low on fuel affects power steering function, and use four interface guard valves to carry out oil circuit control according to flow, relative to utilization electromagnetic valve and sensory-control system structure simple, cost is lower, and this utility model follower substitutes servo cylinder to be had and turn to synchronism preferably.

Fig. 2 is the front elevation of the utility model embodiment;
Fig. 3 is the birds-eye view of the utility model embodiment;
Fig. 4 is the constructional drawing of the utility model guard valve.
Detailed description of the invention
In order to further describe technical characterstic of the present utility model and effect, below in conjunction with the drawings and specific embodiments, the utility model is described further.
shown in Fig. 1-Fig. 4, comprise intercommunication Fuel Tanking Unit 1, steering blade pump 2, jury pump 3, guard valve 4, deflector 5 and follower 6; Guard valve 4, deflector 5, steering blade pump 2 and jury pump 3 are all connected with intercommunication Fuel Tanking Unit 1, and guard valve 4 is also connected with steering blade pump 2, jury pump 3 and deflector 5, and deflector 5 is connected with follower 6.
Further, described intercommunication Fuel Tanking Unit 1 is made up of the first oil tank 11 and the second oil tank 12, one 11, the 2 12 oil tank is connected by an oil pipe, and the first oil tank 11 is connected with deflector 5 and deflector blade-type pump 2, and the second oil tank 12 is connected with guard valve 4 and jury pump 3.
In order to provide warning when driving engine or steering blade pump break down, described guard valve 4 is also connected with a stand by lamp 13.
Described guard valve 4 forms primarily of change-over valve 41, flow regulating valve 42, reducing valve 43, first check valve 44 and the second check valve 45, guard valve 4 is provided with interface P1, P2, A, T interface P1, P2, A, T and is connected with steering blade pump 2, jury pump 3, deflector 5 and the second oil tank 12 respectively, and stand by lamp 13 is connected on reducing valve 43.
During use, the utility model by traditional single loop hydrostatic steering system basis by jury pump 3 being contained in problem auxiliary gear box 7 or change speed gear box forming double loop steering swivel system and can not turn to when engine off or steering blade pump 2 break down in normal traveling to solve vehicle, when flame-out or steering blade pump 2 breaks down time provide power steering by jury pump 3 thus realize turning function of meeting an urgent need.
When automotive engine and steering blade pump 2 all normally work, the high pressure oil mass that steering blade pump 2 provides is normal, and high pressure oil enters deflector 5 by guard valve 4 and follower 6 provides power steering function.Now, the high pressure oil that jury pump 3 provides, by guard valve 4 times the second oil tanks 12, does not participate in power-assisted.
When automotive engine or steering blade pump 2 break down, steering blade pump 2 cannot provide required high pressure oil flow, the high pressure oil that steering blade pump 2 provides enters deflector 5 and follower 6, the high pressure oil that jury pump 3 provides enters deflector 5 and follower 6 by guard valve, now jury pump 3 and steering blade pump 2 Dual-pump flow-converging provide and turn to, stand by lamp 13 is lighted, and provides fault warning prompting.
Above-described embodiment does not limit the utility model in any form, and all technical schemes taking the form of equivalent replacement or equivalent transformation to obtain, all drop within protection domain of the present utility model.
