The ECE regulation in Europe just defines various automobile when entering the Turning travel state of regulation Turning radius with the speed of a motor vehicle of 10km/h from straight-line travelling, the minimum requirements of steering swivel system intact and time to turn after breaking down and steering force; And at present the emergent steering hydraulic pump of great majority is installed on gearbox output or part-time case or drive axle, with transmission shaft run-in synchronism, as long as there is speed of a motor vehicle steering hydraulic pump of meeting an urgent need to operate always, thus cause the loss of larger energy.
In sum, existing hydraulic power-assist steering system can not meet the demands.
Utility model content
Goal of the invention: the purpose of this utility model is to solve the deficiencies in the prior art, a kind of emergent electrobus electric hydraulic power-assisted steering system is provided, two cover steering swivel systems are included in the utility model, the basis of traditional electrohydraulic steering system adds a set of emergency power system, under the main operating mode lost efficacy for steering swivel system, the utility model can by oil pressure, the variable signal of flow feedback sends magnetic clutch controller to, automatically in conjunction with magnetic clutch, kinetic energy is provided to steering swivel system by emergent steering swivel system, thus achieve emergent turning function, great raising usage safety performance.
Technical scheme: one of the present utility model is met an urgent need electrobus electric hydraulic power-assisted steering system, comprises motor, deflector and the main steering swivel system that is parallel in deflector and emergent steering swivel system;
Described main steering swivel system comprises main steering pump and main steering oil reservoir, is communicated with the first high pressure fuel pipe between main steering pump and deflector, is communicated with the first oil inlet between main steering oil reservoir and main steering pump, is communicated with the first oil return pipe between main steering oil reservoir and deflector;
Described emergent steering swivel system comprises emergent steering pump, belt pulley and magnetic clutch, emergent steering pump is arranged on emergent steering pump belt wheel, emergent steering pump belt wheel is connected to one end of motor pulley by belt, emergent steering pump is communicated in deflector by the second high pressure fuel pipe, emergent steering pump is communicated in emergent steering oil reservoir by the second oil inlet, and described emergent steering oil reservoir is communicated in deflector by the second oil return pipe; The other end of described belt pulley connects and magnetic clutch;
The both sides of described motor are connected to main steering pump and magnetic clutch respectively by output shaft.
Further, described first high pressure fuel pipe is provided with pressure sensor.
Further, described first oil return pipe is provided with flow sensor.
For ease of monitoring and gathering pressure data and data on flows, described magnetic clutch is provided with controller.
Beneficial effect: the utility model drives main steering swivel system and emergent steering swivel system respectively by motor, to ensure the normal work of steering swivel system, main steering swivel system and emergent steering swivel system with the use of, under the operating mode that main steering swivel system lost efficacy, the utility model can send the variable signal of oil pressure, flow feedback to magnetic clutch controller, then automatically in conjunction with magnetic clutch, there is provided kinetic energy to main steering swivel system by emergent steering swivel system, thus achieve emergent turning function, greatly improve safety in utilization and meet associated safety regulation.Further, under nominal situation, emergent steering pump, without the need to idle running, while content with funtion demand, also saves electrobus battery power consumption greatly.
In sum, the utility model structure is ingenious, and safety performance is high, and power supply less energy consumption has wide market outlook.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below technical solutions of the utility model are described in detail, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 1, one of the present utility model is met an urgent need electrobus electric hydraulic power-assisted steering system, comprises motor 13, deflector 1 and the main steering swivel system be parallel in deflector 1 and emergent steering swivel system; Main steering swivel system comprises main steering pump 17 and main steering oil reservoir 11, main steering pump 17 is connected to deflector 1 by the first high pressure fuel pipe 18, main steering pump 17 is connected to main steering oil reservoir 11 by the first oil inlet 16, is communicated with the first oil return pipe 15 between main steering oil reservoir 11 and deflector 1; Emergent steering swivel system comprises emergent steering pump 7, belt pulley 2 and magnetic clutch 5, emergent steering pump 7 is arranged on emergent steering pump belt wheel 4, emergent steering pump belt wheel 4 is connected to one end of motor pulley 2 by belt 3, emergent steering pump 7 is communicated in deflector 1 by the second high pressure fuel pipe 8, emergent steering pump 7 is communicated in emergent steering oil reservoir 10 by the second oil inlet 9, and emergent steering oil reservoir 10 is communicated in deflector 1 by the second oil return pipe 12; The other end of motor pulley 2 connects and magnetic clutch 5; The both sides of motor 13 are connected to main steering pump 17 and magnetic clutch 5 respectively by output shaft 14.
