Description
Technical field
Motor steering pump attachment system for electric vehicle of the present invention relates to a kind of power steering device of used for electric vehicle, especially can solve the bigger pure electric automobile power steering problem of quality by failure-free.
Background technology
At present, at electronlmobil, especially known steering boost system or does not have servo-steering with regard to several modes on the pure electric automobile, and this situation can be born at car mass hour chaufeur, but just is difficult to bear when car mass is big.Be exactly EPS (electric boosting steering system), adopt non-brush permanent-magnet DC motor control to turn to, this pattern is exactly that reliability can not get solving.Be exactly to drive in addition, when automobile stops at the crossing, urban district, also continuing consumed power with helper motor, quite very uneconomical the electric energy of preciousness for electronlmobil.Therefore the urgent problem that solves electronlmobil steering swivel system reliability and when of short duration the parking, turn to power consumption.
Summary of the invention
The purpose of motor steering pump attachment system for electric vehicle of the present invention is the problem in order to overcome traditional electric automobile steering swivel system reliability and to turn to power consumption when of short duration stop, the invention provides a kind of by main motor direct-drive, the approximate power-steering safe and reliable servo-steering scheme of orthodox car.
The technical scheme that motor steering pump attachment system for electric vehicle of the present invention adopted is: motor steering pump attachment system for electric vehicle comprises motor, connects support and power assistance pump for steering; Connect support and comprise the motor butt flange and is connected platform, motor butt flange one side be connected the platform captive joint, described motor butt flange is a circular ring type, the overall diameter of annulus overall dimensions and motor is big or small consistent, the connection platform is square; The motor butt flange is provided with through hole and draw-in groove, connect platform and be provided with the boost pump mounting hole, the motor butt flange is sleeved on the rear side housing of motor, captive joint with motor by screw, draw-in groove is installed on the rear side housing projection of motor, power assistance pump for steering by tie bolt be connected the platform captive joint; The power assistance pump for steering shaft end is equipped with belt pulley II, and the motor shaft rearward end is equipped with belt pulley I, and belt pulley II links to each other with belt pulley I by belt.Thereby guaranteed can by the belt pulley I of active motor output shaft rear end can the direct drive power assistance pump for steering belt pulley II, guaranteed the reliability of electronlmobil steering boost system.
Described motor adopts commercially available double end output motor, and an end drives electronlmobil, and the other end drives power assistance pump for steering.
It is the double end output motor that the present invention requires driving motor for electric automobile, and an end drives electronlmobil, and the other end drives power assistance pump for steering; Power assistance pump for steering is fixed together by connecting support and motor, motor one termination belt pulley, when motor rotates, belt pulley rotates by the belt pulley that belt drives power assistance pump for steering, power assistance pump for steering output hydraulic oil, be the steering boost system pressure boost power of electronlmobil, this moment just servo-steering has been arranged, chaufeur just can feel turn to light.
Motor steering pump attachment system for electric vehicle of the present invention is reasonable in design, simple in structure, practical, can be when automobile runs into red parking power-assisted not, well saved electric energy.Owing to be by the active motor direct-drive, so it has quite high reliability.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a motor steering pump attachment system for electric vehicle structural representation of the present invention.
Fig. 2 is that the motor steering pump of motor steering pump attachment system for electric vehicle of the present invention connects the supporting structure scheme drawing.
The specific embodiment
With reference to accompanying drawing 1～2, motor steering pump attachment system for electric vehicle comprises motor 1, connects support 2 and power assistance pump for steering 3; Connect support and comprise motor butt flange 2 and is connected platform 5, motor butt flange 2 one sides be connected platform 5 captive joints, described motor butt flange 2 is circular ring types, the overall diameter of annulus overall dimensions and motor 1 is big or small consistent, connection platform 5 is square; Motor butt flange 2 is provided with through hole 6 and draw-in groove 7, connect platform 5 and be provided with boost pump mounting hole 8, motor butt flange 2 is sleeved on the rear side housing of motor 1, captive joint with motor 1 by screw, draw-in groove 7 is installed on the rear side housing projection of motor 1, and power assistance pump for steering 3 passes through tie bolt 9 and is connected platform 5 captive joints; Power assistance pump for steering 3 shaft ends are equipped with belt pulley II 10, and the motor shaft rearward end is equipped with belt pulley I 11, and belt pulley II 10 links to each other with belt pulley I 11 by belt 4.Thereby guaranteed the initiatively belt pulley II 10 of the belt pulley I 11 energy direct drive power assistance pump for steerings 3 of motor output shaft rear end, guaranteed the reliability of electronlmobil steering boost system.
Described motor adopts commercially available double end output motor, and an end drives electronlmobil, and the other end drives power assistance pump for steering.
