It is always working condition that key, which opens either parking or driving power assistance pump for steering, therefore energy consumption is larger.
The content of the invention
The technical problem to be solved in the present invention is overcome the deficiencies in the prior art, there is provided a kind of automobile-used steering of electric helps
Force system.
In order to solve the above technical problems, the technical solution used in the present invention is：
A kind of automobile-used steering boost system of electric, including power assistance pump for steering and steering wheel, the oil-out of power assistance pump for steering with
It is connected between the oil inlet of steering wheel by hydraulic oil pipe, and check valve is additionally provided with hydraulic oil pipe；The check valve with
Hydraulic oil pipe between steering wheel is provided with threeway, and the oil-out of check valve is connected with a mouth of threeway, steering wheel
Oil inlet is connected with a mouth of threeway, and the 3rd mouth of the threeway is connected with accumulator；The accumulator stores up including high pressure
Gas tank and the air cavity and oil pocket being located in high pressure tank, and the hydraulic fluid port of oil pocket is connected with the 3rd mouth of threeway.
Further, the pressure sensor of measurement wherein pressure is additionally provided with the high pressure tank, and the pressure passes
Sensor is connected by controller with the motor that driving power assistance pump for steering operates.
Further, the air inlet of the air cavity is provided with charge valve.
Further, the accumulator is bladder accumulator or piston accumulator.
It is using beneficial effect caused by above-mentioned technical proposal：
The present invention is stored when steering wheel does not work by being mounted directly an accumulator between power assistance pump for steering and steering wheel
Excess energy, certain complementary capabilities are directly provided by accumulator when steering wheel use, so that steering boost system can
To use low power power assistance pump for steering, compared with prior art, more than twice of power, and power assistance pump for steering can be reduced
Any control system of the continuous work without changing electric car, so that new energy electric motor vehicle had not only reduced power but also increased
Course continuation mileage.
The present invention further controls what driving power assistance pump for steering operated by detecting the pressure in high pressure tank
Motor.Gas pressurized in air cavity to steering wheel is used to the lower limit of pressure, the gas when hydraulic fluid pressure raises by charge valve
Body starts to compress, and the hydraulic oil in hydraulic oil pipe stores into oil pocket；When the hydraulic oil stored in oil pocket reaches using pressure
During the power upper limit, pressure sensor detection pressure signal is simultaneously stalled by controller controlled motor, and power assistance pump for steering is stopped.By
In the bulbs of pressure of gas, while hydraulic oil has certain storage capacity, therefore, when steering wheel rotates just by accumulator oil pocket
The hydraulic oil of storage drives steering wheel work；When pressure is soon dropped to using low pressure limit, controller controlled motor continues to transport
Turn, power assistance pump for steering is started working, and so reduces the workload of power assistance pump for steering, and prior art ratio, can save energy 80% with
On.

Embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
As shown in figure 1, the first embodiment of the present invention, a kind of automobile-used steering boost system of electric, including turn to and help
Power pump 1 and steering wheel 2, it is connected between the oil-out and the oil inlet of steering wheel 2 of power assistance pump for steering 1 by hydraulic oil pipe 3, and
Check valve 4 is additionally provided with hydraulic oil pipe 3；Threeway 5 is provided with hydraulic oil pipe 3 between the check valve 4 and steering wheel 2, and
And the oil-out of check valve 4 is connected with a mouth of threeway 5, the oil inlet of steering wheel 2 is connected with a mouth of threeway 5, described
3rd mouth of threeway 5 is connected with accumulator 6；Accumulator 6 is bladder accumulator or piston accumulator.Accumulator 6 includes
High pressure tank and the air cavity and oil pocket being located in high pressure tank, the air inlet of air cavity are provided with charge valve 7, and oil pocket
Hydraulic fluid port is connected with the 3rd mouth of threeway 5.
In the present embodiment, an accumulator 6 is directly only installed between power assistance pump for steering 1 and steering wheel 2, in accumulator 6
Gas pressure be less than the use pressure of steering wheel, the use pressure of general direction machine is 16-18MPa, the gas pressure of accumulator
Power is set as 14-15MPa.Because steering wheel 2 need not continuously work, and accumulator 6 has enough complementary capabilities, so turns to
The can of boost pump 1 uses small-power steering axial force pump, and compared with prior art, power assistance pump for steering 1 can reduce more than twice
Power.The present embodiment uses low power power assistance pump for steering, and power assistance pump for steering continuously works without changing electric car
