Abstract
The utility model relates to an electric power steering gear of a car, including an electronic controller. The electronic controller consists of a power module, a motor drive module and a micro-controller module, which are relatively independent, and arranged in a kickstand. The utility model is characterized in that the micro-controller module, the power module and the motor module are separately arranged to effectively in reduce the mutual interference of these three modules, greatly increasing the reliability of the system. The motor driver module is arranged in the lowest deck and is fixed with the kickstand and the back of the motor drive module closely contacts with the heat sink. Therefore, the heat produced by the motor drive module is smoothly discharged through the heat sink, reducing the temperature of the entire electronic controller to enhance the stability and environmental adaptability. The stack installation manner of the three modules narrows installation space so that the whole structure becomes more compact and easy to install.
Description
Technical field
The utility model relates to a kind of automobile component, particularly a kind of vehicle electric power-assisted steering device.
Background technology
Steering apparatus for vehicles requires under the low speed of a motor vehicle agile, easy to operate comfortable, under the high speed of a motor vehicle, turn to steadily, handling strong, improve the comfortableness drive and can be handling, therefore need be under the low speed of a motor vehicle big power-assisted, little power-assisted under the middle speed of a motor vehicle, be with damping under the high speed of a motor vehicle, often achieve this end at present by vehicle electric power-assisted steering device.
Existing vehicle electric power-assisted steering device, it comprises torque transducer, vehicle speed sensor, electronic controller, motor, by torque transducer, vehicle speed sensor the torque of steering wheel and the speed of automobile are input in the electronic controller, pass through the processing of electronic controller again, output current is controlled turning to of steering wheel to motor with motor.Electronic controller wherein is made up of power supply, microcontroller and motor drive module, and it is made of one, and so not only volume is big, and is easy to form the phase mutual interference between each functional module, and the reliability of vehicle electric power-assisted steering device is reduced greatly.Simultaneously since driver module distribute a large amount of heats or since ambient temperature raise, the working temperature fast rise of whole steering gear, this can cause the reduction of the service behaviour of electric booster steering device, has therefore reduced the adaptive capacity of system to ambient temperature.
The utility model content
Technical problem to be solved in the utility model is to overcome the above-mentioned deficiency of prior art and a kind of vehicle electric power-assisted steering device is provided, and makes that it is rational in infrastructure, disturbs less, wide adaptability.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
Vehicle electric power-assisted steering device comprises electronic controller, it is characterized in that: described electronic controller is made up of three relatively independent power modules, motor drive module, micro controller modules and is formed by connecting, and is installed in the support.
For making structure compact more, dwindle the volume of product, above-mentioned three modules adopt stacked mode to connect.
For dustproof anti-tampering, above-mentioned support loam cake housing.
Be to reduce the temperature of electronic controller, motor drive module is at the orlop of three modules and be fixed on the support, and the motor drive module back side is provided with fin.
Compared with prior art, advantage of the present utility model is:
1, micro controller module, power module, motor module are separately formed relatively independent separately module, can reduce the phase mutual interference of these three intermodules effectively, the reliability of system is improved greatly.
2, motor drive module is installed in orlop, and fix with support, the motor drive module back side closely contacts with fin, thereby discharge by the heat that fin produces motor drive module smoothly, thereby reduce the temperature of whole electronic controller, improve its stability and the adaptability of environment.
3, the mode of three stacked installations of module layering has been dwindled installing space, makes whole modular construction compact, small and exquisite more, be convenient to install, so whole electronic controller compact conformation, volume is little.
Description of drawings
Fig. 1 is the stereogram of the utility model embodiment.
Fig. 2 is the explosive view of the utility model embodiment.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the electronic controller of vehicle electric power-assisted steering device comprises micro controller module 2, power module 3, driver module 7, and micro controller module 2 and driver module 7 are fixing by connector 6, and place in the mounting bracket 4, and outer cover shell 1.
Above-mentioned three parts micro controller modules 2, power module 3, motor drive module 7 link together by overlapped way, and in driver module 7 back side fixing cooling fins 5, so that the heat that motor drive module 7 produces in time distributes, thereby prevent the overheated of power module, improve its serviceability and useful life.
When above-mentioned vehicle electric power-assisted steering device is worked, power module provides stable power to micro controller module, and under the control of microcontroller, provide big electric current by relay to motor, microcontroller partly detects the speed of a motor vehicle, rotating speed, the input torque sensor signal, produce control signal by neural network algorithm and fuzzy control principle, the control motor drive module, produce the corresponding driving electric current, drive motors produces corresponding power steering, motor drive module is formed the H bridge-type by four driving tubes, produce drive current by the pwm signal that microcontroller is produced, drive motors work, thus regulate power steering.
