Description
Technical field
The present invention relates to a kind of electric boosting steering system, belongs to gear reducer component technical field.
Background technology
It is initially mechanical in automobile steering system, but its mechanism relative clumsy, driver's heavy load, causes
It is rarely employed in road vehicle, is only used at present in the less occasion of a few thing load；Nineteen fifty-three hydraulic power-assisted steering
System obtains first Application in General Motors Corporation；In the later stage eighties, the hydraulic power-assist steering system for becoming speed reducing ratio obtains
It is applied successfully, for its opposing hydraulic steering there is good maneuvering performance to occur energy-saving and environment-friendly more becoming afterwards
Flow pump hydraulic power-assist steering system and electric hydraulic power-assisted steering ((EHPS) system；Variable delivery pump servo steering system is in vapour
In the case that car is in higher travel speed or need not turn to, the flow of pump can be reduced accordingly, so as to reach saving
The purpose of the energy；EHPS is using motor driving steering pump, and steering pump with engine synchronization without rotating again, it is not necessary to which steering helps
Steering pump is closed when power, can largely save the energy；It is but difficult due to the inherent characteristic of hydraulic steering system
To realize the breakthrough in efficiency, substituted by electric boosting steering system (EPS) and have become a kind of inexorable trend.
The content of the invention
To solve the above problems, the present invention proposes a kind of electric boosting steering system, directly pass through the output of motor
Power-assisted is provided to driver, motor only just works when turning to, and almost without power consumption when without turning to, makes vapour
Car has more preferable fuel economy.
The electric boosting steering system of the present invention, including wheel, steering wheel, clutch and electronic control unit；The car
Vehicle speed sensor is installed on wheel；Steering wheel rotation sensor is installed on the steering wheel；The vehicle speed sensor, steering wheel
Rotation sensor and clutch are connected with electronic control unit respectively；The electronic control component is by power driving circuit and directly
Galvanic electricity motivation connects；Its output terminal of the dc motor is connected by reducing gear with rack and pinion mechanism；The gear teeth
Bar mechanism is connected with wheel.
Further, the steering wheel rotation sensor includes torque sensor and speed probe.
Further, the reducing gear is worm gear mechanism.
Compared with prior art, electric boosting steering system of the invention, directly passes through the output of motor to the present invention
Power-assisted is provided to driver, motor only just works when turning to, and almost without power consumption when without turning to, makes vapour
Car has more preferable fuel economy；Have at the same time light-duty compact, assembling is rapid, is easy to adjust, noise and waste oil, exhaust emission
The advantages of small.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the present invention.
Each component is labeled as in attached drawing：1- wheels, 2- steering wheels, 3- electronic control units, 4- vehicle speed sensor, 5- direct currents
Motor, 6- reducing gears, 7- rack and pinion mechanisms, 8- torque sensors.
Embodiment
As shown in Figure 1, the electric boosting steering system of the present invention, including wheel 1, steering wheel 2, clutch（It is not shown）With
Electronic control unit 3；Vehicle speed sensor 4 is installed on the wheel 1；Steering wheel rotation sensing is installed on the steering wheel 2
Device；Vehicle speed sensor 4, steering wheel rotation sensor and the clutch（It is not shown）It is connected respectively with electronic control unit 3；Institute
State electronic control component 3 and pass through power driving circuit（It is not shown）It is connected with dc motor 5；Its is defeated for the dc motor 5
Outlet is connected by reducing gear 6 with rack and pinion mechanism 7；The rack and pinion mechanism 7 is connected with wheel 1.
The steering wheel rotation sensor includes torque sensor 8 and speed probe（It is not shown）.
The reducing gear 6 is worm gear mechanism.
The electric boosting steering system of the present invention, the signal deciding direct current that electronic control unit is exported according to each sensor
The rotation direction of motivation and optimal power torque, control signal is sent to dc motor and clutch, passes through power drive electricity
Road controls the rotation of dc motor, and the output of dc motor is after reducing gear deceleration torque, drive gear rack machine
Structure, produces corresponding power steering；Power-assisted directly is provided to driver by exporting for motor, motor is only when turning to
Just work, almost without power consumption when without turning to, make automobile that there is more preferable fuel economy；Have at the same time light-duty
Compact, assembling is rapid, is easy to adjust, noise and waste oil, the advantages of exhaust emission is small.
Above-described embodiment, is only the better embodiment of the present invention, therefore all structures described according to present patent application scope
Make, the equivalent change or modification that feature and principle are done, be included in the range of present patent application.
