Description
Technical field
The utility model is related to a kind of electric boosting steering system, belongs to reductor component technical field.
Background technology
In automobile steering system, it is initially mechanical, but its mechanism relative clumsy, driver's heavy load, cause
It is rarely employed in road vehicle, is only used in the less occasion of a few thing load at present；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 is obtained
Successful Application, for its opposing hydraulic steering have good maneuvering performance after occur in that more can energy-conserving and environment-protective change
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 comparing travel speed high or need not turn to, the flow of pump can be reduced accordingly, so as to reach saving
The purpose of the energy；EHPS uses motor-driven steering pump, and steering pump with engine synchronization without being rotated again, it is not necessary to which steering is helped
Steering pump is closed when power, can largely save energy；But it is 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.
Utility model content
To solve the above problems, the utility model proposes a kind of electric boosting steering system, directly by motor
Export and provide power-assisted to driver, motor only just works when turning to, when not turned to almost without power consumption,
Make automobile that there is more preferable fuel economy.
Electric boosting steering system of the present utility model, including wheel, steering wheel, clutch and electronic control unit；Institute
State and vehicle speed sensor is installed on wheel；Steering wheel rotation sensor is installed on the steering wheel；The vehicle speed sensor, turn
It is connected with electronic control unit respectively to disk rotation sensor and clutch；The electronic control component passes through power driving circuit
It is connected with dc motor；The dc motor its output end is connected by reducing gear with pinion and rack；The tooth
Wheel rackwork is connected with wheel.
Further, the steering wheel rotation sensor includes torque sensor and speed probe.
Further, the reducing gear is worm-and-wheel gear.
The utility model compared with prior art, electric boosting steering system of the present utility model, directly by electronic
Exporting for machine provides power-assisted to driver, and motor only just works when turning to, when not turned to almost without power
Consumption, makes automobile have more preferable fuel economy；Have simultaneously light-duty compact, assembling is rapid, it is easy to adjust, noise and useless
The small advantage of oil, exhaust emission.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Each part is labeled as in accompanying drawing：1- wheels, 2- steering wheels, 3- electronic control units, 4- vehicle speed sensor, 5- direct currents
Motor, 6- reducing gears, 7- pinion and racks, 8- torque sensors.
Specific embodiment
As shown in figure 1, electric boosting steering system of the present utility model, including wheel 1, steering wheel 2, clutch（Do not scheme
Show）With electronic control unit 3；Vehicle speed sensor 4 is installed on the wheel 1；Steering wheel rotation is installed on the steering wheel 2
Sensor；The vehicle speed sensor 4, steering wheel rotation sensor and clutch（It is not shown）Connect with electronic control unit 3 respectively
Connect；The electronic control component 3 passes through power driving circuit（It is not shown）It is connected with dc motor 5；The dc motor 5
Its output end is connected by reducing gear 6 with pinion and rack 7；The pinion and rack 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-and-wheel gear.
Electric boosting steering system of the present utility model, electronic control unit is straight according to the signal deciding that each sensor is exported
The rotation direction and optimal power torque of motor are flowed, control signal is sent to dc motor and clutch, driven by power
Dynamic circuit controls the rotation of dc motor, the output of dc motor after reducing gear slows down and increases and turn round, drive gear teeth
Bar mechanism, produces corresponding power steering；Power-assisted directly is provided to driver by exporting for motor, motor is only turning
To when just work, when not turned to almost without power consumption, make automobile that there is more preferable fuel economy；Have simultaneously
Light-duty compact, assembling is rapid, it is easy to adjust, noise and the small advantage of waste oil, exhaust emission.
Above-described embodiment, is only better embodiment of the present utility model, therefore all according to the utility model patent claim
The equivalent change or modification that described construction, feature and principle are done, is included in the utility model patent claim.
