Description
Technical field
The present invention relates to electric power steering technical field, more particularly to a kind of electric power steering system for vehicle
System.
Background technology
Steering pump in motorcar electric hydraulic power-assist steering system can be by controlled motor rotating speed and output flow
Steering hand-power weight in solve the problems, such as vehicle traveling process, but still there are following problems：When automobile is not turned to, band
The motor of dynamic steering pump operating still maintains to be not less than the rotating speed of 500 turns/min, and energy consumption is larger；Due to the limit of motor power (output)
System so that above-mentioned electric hydraulic power-assisted steering system is not suitable for heavy duty vehicle and electric coach, new forms of energy motor bus etc.
The vehicle of larger power steering is needed, the scope of application is less.
In order to solve such defect, a kind of electric boosting steering system for vehicle has been introduced, including motor, turned

Power output；What the ECU controllers and the hydraulic electromagnetic proportioning valve electrically connected to control corresponding magnetic valve opens off and on
Open size；The output end of the hydraulic cylinder is connected with the input of the steering gear.
In concrete utilization, torque sensor is often arranged on one end of the frame, and described frame one end is provided with torsion
The mode of square sensor is that torque sensor silk is connected into described frame one end by Threaded Connector Coupling, so has such defect：
Being screwed into from high to low during execution is not easy, namely silk connects, releasing when silk connects to back-out from low to high, so
Process be not easy to perform；Silk socket part must must project outer wall in the frame, and protuberance is not often little, and shared region is just not yet
It is little；The recoverable strain of Al alloy block is relied in addition, and construction diversification is not enough, constructs also not pleasing.
And currently in order to dust-proof, ECU controllers are often arranged in the casing being fixed in frame, because ECU controllers
Can generate heat during execution, if hot-fluid cannot be excluded in real time, hot gas in casing is increased, allow ECU controllers such
Frequent Troubles under environment, or even there is the problem for burning out；The casing lower end for arranging ECU controllers at present in addition is substantially
Copper alloy bracing frame, quality is not little, if casing being moved as palpus, being carried out and is safeguarded, it is impossible to easily move, so generate to maintenance tired
It is difficult.
The content of the invention
To solve the above problems, the invention provides a kind of electric boosting steering system for vehicle, effectively prevent
It is not easy to execution, shared region is not little, construction diversification is not enough, it is also not pleasing to construct, allow ECU controllers under such circumstances
