Description
Technical field
The present invention relates to electric power steering technical field, in particular to a kind of electric power steering system for vehicle
System.
Background technique
Steering pump in motorcar electric hydraulic power-assist steering system can pass through control motor speed and output flow
It solves the problems, such as the steering hand-power weight in vehicle traveling process, but still remains following problems: when automobile does not turn to, band
The motor of dynamic steering pump operating still maintains the revolving speed not less than 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 energy motor bus etc.
Need the vehicle of larger power steering, smaller scope of application.
To solve this kind of defect, it has introduced a kind of electric boosting steering system for vehicle, including motor, has turned
To oil pump, steering reservoir, accumulator, ECU controller, hydraulic electromagnetic proportioning valve, hydraulic cylinder, diverter, torque sensor, corner
Sensor, vehicle speed sensor and pressure sensor；The motor, steering pump, steering reservoir, accumulator, ECU control
Device, hydraulic electromagnetic proportioning valve, hydraulic cylinder, diverter, torque sensor, rotary angle transmitter, vehicle speed sensor and pressure sensing
Device is set in the rack of automobile；The input terminal of the output shaft of the motor and the steering pump is sequentially connected, and described turn
The upper liquid level of the hydraulic oil in the steering reservoir is immersed in the oil inlet of oil pump hereinafter, the oil outlet of the steering pump is logical
Hydraulic oil pipe is crossed to be connected to the oil inlet of the hydraulic cylinder；The accumulator is arranged by a three-port structure part in the steering
On hydraulic oil pipe between oil pump and the hydraulic cylinder；Hydraulic electromagnetic proportioning valve setting the accumulator with it is described hydraulic
The flow and pressure size of the hydraulic oil of the accumulator outflow are controlled on hydraulic oil pipe between cylinder；The pressure sensor
It is arranged on the hydraulic oil pipe between the accumulator and the hydraulic electromagnetic proportioning valve for detecting in the accumulator
The pressure size of hydraulic oil；The oil outlet of the hydraulic cylinder is connected to the oil return opening of the steering reservoir；The torque sensor,
Rotary angle transmitter and vehicle speed sensor are electrically connected described to pass to the electric signal respectively obtained with the ECU controller
ECU controller；The pressure controller is electrically connected with by the pressure value of hydraulic oil in the accumulator with the ECU controller

Output power；The ECU controller and the hydraulic electromagnetic proportioning valve, which are electrically connected, opens off and on control corresponding solenoid valve
Open size；The input terminal of the output end of the hydraulic cylinder and the diverter is sequentially connected.
In specific use, one end of the rack is often arranged in torque sensor, and described rack one end is provided with torsion
The mode of square sensor is that torque sensor silk is connected to described rack one end by Threaded Connector Coupling, can be had the disadvantage that in this way
Being screwed into from high to low during execution is not easy namely silk connects, release when silk connects to back-out from low to high, in this way
Process be not easy to execute；Silk socket part must must protrude the outer wall in the rack, and protruding portion is not often small, and shared region is just not yet
It is small；In addition the recoverable strain of Al alloy block is relied on, construction diversification is insufficient, constructs also not pleasing.
And currently in order to dust-proof, ECU controller is often arranged in the cabinet being fixed on the rack, because of ECU controller
It can generate heat when execution, if hot-fluid can not exclude in real time, increase hot gas in cabinet, allow ECU controller such
Frequent Troubles under environment, or even the problem of burn out；In addition the cabinet lower end of setting ECU controller is substantially at present
Copper alloy support frame, quality is not small, if moving cabinet as palpus, carrying out maintenance, can not be easy to move, produce in this way to maintenance tired
It is difficult.
Summary of the invention
To solve the above problems, being effectively prevented the present invention provides a kind of electric boosting steering system for vehicle
Be not easy to execute, shared region is not small, construction diversification is insufficient, construction is not also pleasing, allow ECU controller under such circumstances
Frequent Troubles or even occur burn out, produce difficult defect to maintenance.
