32, electromagnetic coil 41, diverter oil cylinder 51, diverter pull rod
Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, below in conjunction with specific embodiment pair
This programme is further discussed in detail.
As shown in Figure 1 to Figure 2, the embodiment of the invention provides a kind of hydraulic power-assisted steering mechanisms comprising rotary valve liquid
Press power-assisted steering device 11, regulating valve and control device;Oil inlet is provided on the shell of rotary valve hydraulic power steering gear 11 to connect
Mouth 21, oil inlet interface 21 is connected with the oil inlet passage of shell, and oil inlet interface 21 passes through oil inlet passage to rotary valve hydraulic booster
Input hydraulic pressure oil in diverter 11;The junction of oil inlet interface 21 Yu oil inlet passage is arranged in regulating valve;Control device and adjusting
Valve is connected, and control device can be adjusted the openings of sizes of the valve port of regulating valve.It is helped it is understood that rotary valve is hydraulic
When the general work principle of power diverter 11 is driver turn steering wheel, rotary valve hydraulic power-assisted steering is driven by torque arm
The spool of device 11 rotates in valve pocket, so that the hydraulic oil of 41 two sides of diverter oil cylinder has pressure difference, so that turning to
Piston in device oil cylinder 41 moves, and then drives diverter pull rod 51 mobile, realizes power steering;The rotary valve is hydraulic to be helped
The specific structure of power diverter 11 is identical as the structure of rotary valve hydraulic power steering gear in the prior art, no longer superfluous herein
It states.
Hydraulic power-assisted steering mechanism provided in an embodiment of the present invention, regulating valve are arranged in oil inlet interface 21 and oil inlet passage
Junction, pass through the openings of sizes that control device controls to adjust the valve port of valve, it will be able to entering rotary valve hydraulic booster
The uninterrupted of hydraulic oil in diverter is controlled, to realize to the power steering of rotary valve hydraulic power steering gear
The adjustment of size preferably mentions so that different drivers can adjust the size of power steering according to the demand of itself
The high driver comfort of driver.
As shown in Fig. 2, regulating valve can be solenoid valve 31, there is electromagnetic coil 32 on solenoid valve 31;Control device passes through
The size of the electric current flowed through in control electromagnetic coil 32, realizes the control of the openings of sizes to the valve port of solenoid valve 31.Using this
Scheme need to only control the size of the electric current flowed through in electromagnetic coil, it will be able to conveniently realize opening to the valve port of solenoid valve 31
The control of mouth size.
Further, control device can be the first controller, adjusting knob, and adjusting knob setting is driving indoor instrument
On table platform, adjusting knob is electrically connected with the first controller.Using this scheme, driver only need to the adjusting knob on instrument desk into
Row rotation, the size information for the angle that the first controller can be rotated according to collected adjusting knob, to electromagnetic coil
The size of middle electric current is controlled, so that the openings of sizes of the valve port of solenoid valve 31 is controlled, so that the size of power steering
It is adjusted, so that power steering reaches the demand of each driver.
Specifically, control device may include second controller, the first button and the second button, the first button and second
Controller electrical connection, the second button are electrically connected with second controller;It is indoor that first button and the second button are arranged at driving
On instrument desk.Using this scheme, the openings of sizes of the valve port of solenoid valve 31 can be set in a numerical value by the first button,
The openings of sizes of the valve port of solenoid valve 31 is set in another numerical value by the second button, so that the hydraulic power-assisted steering
Mechanism can have there are two types of assistant mode, facilitate driver and select to use.It is understood that when pressing the first button, it can
To be set as making the opening of the valve port of solenoid valve maximum, it is properly termed as " comfort mode ", when pressing the second button, Ke Yishe at this time
Being set to keeps the opening of the valve port of solenoid valve 31 minimum, is properly termed as " motor pattern " at this time;Under " comfort mode ", hydraulic booster turns
Hydraulic fluid flow rate into mechanism is maximum, and the power steering of vehicle is also just larger, the steering force for needing driver to apply also just compared with
Small, hand-power is small during turning, so that the manipulation of driver is more comfortable;Under " motor pattern ", hydraulic power-assisted steering machine
Hydraulic fluid flow rate in structure is minimum, and full-vehicle steering power-assisted is small, and the steering force for needing driver to apply is with regard to larger, so that turning process
Middle hand-power is sedate.Since the driver having gets used to turning to light when driving vehicle, and some drivers are when driving vehicle
Hand-power is sedate when habit turns to, and driver can select to use above-mentioned mode, be driven with reaching itself according to the driving habit of itself
Sail the requirement of comfort.The transformation that can be realized power steering mode by the first button and the second button, can be in steering force
It is switched under the small biggish motor pattern of comfort mode and steering force, promotes driving pleasure, meet different clients demand, mention
The performance of steering boost system is risen;Certainly, when using adjusting knob, the hydraulic power-assisted steering mechanism can be made to have more
Kind assistant mode.
In order to preferably save the connection between oil inlet interface 21 and the shell of rotary valve hydraulic power steering gear 11,
The bonding strength between oil inlet interface 21 and shell is effectively improved, oil inlet interface 21 and shell can be formed as one formula knot
Structure.
The above is only the preferred embodiment of the present invention, it should be pointed out that these embodiments are merely to illustrate the present invention
Rather than limit the scope of the invention, moreover, after reading the contents of the present invention, relevant technical staff in the field can be with
Various changes or modification are made to the present invention, such equivalent forms equally fall into model defined by the application the appended claims
It encloses.
