Description
Technical field
The present invention relates to a kind of electric steering engine ball-screw transmission mechanism loading flexible damping, steering wheel control
Technical field processed.
Background technology
In using ball-screw as the Electrodynamic Rudder System of deceleration component, ball screw rotates and drives ball
Slide block on leading screw does alternating translational movement, thus promotes steering wheel output shaft to rotate.In transmission process,
Ball-screw can by steering wheel output shaft reaction force acts, ball-screw when different directions rotates,
Slipper push steering wheel on ball-screw exports axial different directions and rotates, so in steering wheel work process
In, ball-screw can be by the reciprocating of two rightabout active forces.When ball-screw rotation side
When conversion, the counteracting force direction that ball-screw is subject to also changes, if now ball-screw
There is gap at two ends, then can produce ball-screw because of the change of Impact direction and move forward and backward, directly affect
The transmission accuracy of steering wheel, affects steering gear system control accuracy and dynamic performance index, causes steering gear system
The faults such as overshoot is big, poor stability occur.For solving the problems referred to above, traditional method is to compress rolling
The bearing at ballscrew two ends eliminates gap, and this method needs accurately regulation ball-screw bearings at both ends
Pretightning force, the pressure damping that all can affect ball-screw transmission mechanism excessive, too small, thus affect
The performance indications of steering gear system.Even if making ball-screw two ends by regulation repeatedly in normal temperature environment
Bearing pre-fastening, makes steering gear system reach use requirement, but when working in low temperature environment because
Coefficient of thermal expansion difference between steering wheel housing and ball-screw can cause steering gear system ball-screw two end axles
Hold pretightning force and sharply increase that even steering gear system ball-screw is compacted cannot be rotated；Steering gear system is at height
When temperature environment works, because same reason ball-screw bearings at both ends pretightning force reduces rapidly, steering wheel
Generation gap, system ball-screw two ends, thus cause steering gear system in high and low temperature environmental work time property
Can index exceeding standard.So, debug and adapt to the electronic of various working environments in the urgent need to a kind of being easy to
Steering wheel ball-screw transmission mechanism ensures the performance indications of steering gear system.
Summary of the invention
The invention aims to solve ball-screw slowdown type Electrodynamic Rudder System at various temperature shape
The technical barrier of performance indications instability is caused to set due to ball-screw transmission mechanism damping change under state
A kind of electric steering engine ball-screw transmission mechanism loading flexible damping of meter.
It is an object of the invention to be achieved through the following technical solutions:
A kind of electric steering engine ball-screw transmission mechanism loading flexible damping of the present invention, its feature exists
In: comprising: adjusting means (2), elastic element (3), angular contact ball bearing (4) and ball wire
Thick stick (5).
First ball-screw (5) two ends are loaded onto respectively 1 angular contact ball bearing (4), angular contact ball
Bearing (4) uses back-to-back mode to install；Then by the angular contact ball axle of ball-screw (5) one end
Hold (4) outer ring and hold out against on steering wheel housing (6), elastic element (3) is withstood on ball-screw (5)
Other end angular contact ball bearing (4) outer ring；Adjusting means (2) is connected with steering wheel housing (6) and presses
Tight elastic element (3).
Utilize adjusting means (2) to adjust the pressure of elastic element (3), thus compress angular contact ball
The outer ring of bearing (4), makes angular contact ball bearing (4) have certain pretightning force；Pass through angular contact ball
The pretightning force of bearing (4) and reach to make the purpose of the flexible pretension of ball-screw (5), eliminate ball
The gap at leading screw (5) two ends, stable drive, accurately, thus ensure the performance indications of steering gear system.
Can also also add in angular contact ball bearing (4) outer ring held out against on steering wheel housing (6) and shoot
Property device (3), and make the other end of elastic element (3) hold out against on steering wheel housing (6).
Described adjusting means (2) is adjustment sheet.
Described elastic element (3) is disk spring.
Beneficial effect
A kind of electric steering engine ball-screw transmission mechanism loading flexible damping that the present invention proposes, it is to avoid
Traditional method ball-screw bearings at both ends pretightning force, with the drawback of jump in temperature, passes through Compliant pressure
Mode, leading screw bearings at both ends pretightning force changes mitigation under high and low temperature environment, will not produce bearing
The situation that pretightning force is excessive, too small and causes steering gear system performance indications to exceed standard.

Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is done described in detail below.
The electric steering engine ball-screw transmission mechanism loading flexibility damping in the present embodiment, including: spiral shell
Nail 1, adjusting means 2, elastic element 3, angular contact ball bearing 4 and ball-screw 5.
First ball-screw 5 two ends are loaded onto 1 angular contact ball bearing 4, angular contact ball bearing 4 respectively
Back-to-back mode is used to install；Then angular contact ball bearing 4 outer ring at ball-screw 5 two ends is respectively added
Fill 1 elastic element 3, and make the other end of elastic element 3 hold out against on steering wheel housing 6；Regulation
Device 2 is connected with steering wheel housing 6 by screw 1 and is compressed the elastic element 3 away from motor 7.
In the present embodiment, adjusting means 2 is adjustment sheet；Elastic element 3 is disk spring.
This device is under normal temperature environment, through overregulating the ball screw framework resistance obtaining being suitable for steering gear system
Buddhist nun；When steering gear system is in high and low temperature environment, steering wheel housing, ball-screw and angular contact ball axle
The part such as hold and necessarily lead to axial dimension change owing to size is different with material.Owing to disk spring exists,
Now disk spring relies on elastic deformation, alleviates the preload pressure of ball-screw bearings at both ends drastically
Change.Thus avoid the traditional method firm leading screw bearings at both ends pretightning force drawback with jump in temperature.
By the way of this Compliant pressure, leading screw bearings at both ends pretightning force changes slow under high and low temperature environment
With, will not produce that bearing pre-fastening is excessive, too small and the situation that causes steering gear system performance indications to exceed standard.
