Description
Technical field
The present invention relates to automobile experiment auxiliary device technology, specifically a kind of steady test of automobile behaviour is auxiliary with anti-reverse rotatable steering
Help equipment.
Background technique
With the surge of automobile quantity and the raising of speed, traffic accident becomes frequent and severe, automobile operation safety
Problem is increasingly valued by the people.The test side provided according to " GBT 6323-2014 vehicle handling stability test method "
Method, vehicle handling stability test have all carried out stringent regulation to steering angle, speed and frequency, but in automobile test process
The twisting resistance that middle steering wheel is subject to be it is continually changing, in particular by obstacle road surface impact when steering wheel take a turn for the worse and jump
It is dynamic, cause the error and interference in test data.Therefore it is necessary to adopt one kind being capable of the side of preventing in handling and stability experiment
It takes a turn for the worse to disk, and pinpoint steering support device is carried out to corner, turning velocity and steering frequency.
In the design process of steering support device, should meet claimed below: 1) structure is simple, installs convenient quick；2) energy
It is enough mounted in the small space of automobile cab, and reserves reasonable riding space, the visual field and in emergency circumstances for driver
Escape space；3) installation of auxiliary device is without being changed the structure of steering wheel, while to have universality, can adapt to
The steering wheel of different sizes；4) steering wheel angle, turning velocity and steering frequency can be accurately controlled.
In the prior art, the Chinese utility model patent of 207790839 U of Patent No. CN, providing a kind of includes watching
The steering robot for taking motor, exporting fluted disc and support ring, servo motor are installed on the outside of gear cover plate, are set on the inside of gear cover plate
It is equipped with deceleration device, output fluted disc is disposed between upper annular mounting ring and lower annular mounting ring, output fluted disc is cyclic structure,
It exporting between fluted disc and upper annular mounting ring by thin-wall bearing as supporting, thin-wall bearing rotor portion is fixed with output fluted disc,
Thin-wall bearing stationary part is fixed with upper annular mounting ring, and support and positioning output fluted disc of the support ring for thin-wall bearing are under
The fixed servo motor of annular mounting ring can drive output fluted disc and lower annular mounting ring to rotate by deceleration device；Patent No.
102435452 A of CN provides the steering wheel operating device of motor turning machine people a kind of, including clamps disc mechanism, motor
With fixed leverage, wherein clamp the axis of rotation that disc mechanism passes through three clamping structure orientation disks, movable disc and clamping
Disc mechanism is connected by arc chute, guarantees that movable disc can be axially moved within the scope of arc chute with respect to support plate, together
When motor shaft is fixed with the normal work for guaranteeing motor by the stationary part of the fixed motor of a set of fixed leverage, pass through motor
The rotation of shell drives steering wheel, and the angle between three sections of bars of the fixed fixed leverage of device is adjustable, the rotating shaft of vertical pole
It is also adjustable with the connection angle of sucker, to adapt to be consolidated by what mounting position of motor and other test concrete conditions determined
The different setting angles of fixed pole system.
But the device of 207790839 U of device and Patent No. CN of 102435452 A of Patent No. CN all exists
Common disadvantage is: motor is all directly to connect with steering wheel, that is, does not account for the torsion reaction force of steering wheel to motor
Damage and to interference caused by test data.Automobile in the process of moving, due to the out-of-flatness on road surface, and causes steering wheel
The twisting resistance being subject to be it is continually changing, in particular by obstacle road surface impact when, motor is directly connected to steering wheel at this time,
It will cause the impact bounce that steering wheel angle generates moment, interference generated to test data result, damage electricity is possible to when serious
Machine, in addition, both devices be all by design of electrical motor installation on the steering wheel, this results in steering wheel and improves quality excessive, automobile
Since the effect of inertia force can damage steering wheel when passing through potted road surface in driving process.
Summary of the invention
The purpose of the present invention is in view of the deficiencies of the prior art, and a kind of automobile behaviour is provided and surely tests anti-reverse rotatable steering
Ancillary equipment.This equipment can be effectively prevented steering wheel angle during the test and take a turn for the worse, and the test generated misses
Difference, and the torque of motor is effectively transferred to steering wheel, and can adapt to various sizes of steering wheel, it is quick and easy for installation.
Realizing the technical solution of the object of the invention is:
A kind of automobile behaviour is steady to test anti-reverse rotatable steering assistance device, unlike the prior art, including passes through fixed block

Fixed block and lower fixed block are by direction chuck clamping, and bolt can slide in clamping disk sliding slot, in order to adapt to various sizes of direction
Disk.
The fixed leverage includes the worm and gear fixed plate rigidly linked with worm gearing and worm and gear
The external swing rod of fixed plate, wherein fixed plate one end connects swing rod in the form of revolute pair, and swing rod possesses two sections of connecting rods, even
Tying is also to be connected between bar using revolute pair, which is with prior art difference can be by the rotating shaft of connecting rod
It adjusts the angle, so that the adjustment of worm gearing installation site up and down is realized, to adapt to the peace of different angle
Dress.
After the equipment of the technical program is installed, by controlling revolving speed, torque and the positive and negative rotation frequency of servo motor, by
Bowden cable delivers torque to worm gearing, then delivers torque to clamp system by turbine wheel shaft, clamps at this time
Mechanism and steering wheel are rigidly connected, and worm gearing is fixed by fixed leverage, so as to control turning for steering wheel
Angle, revolving speed and steering frequency, during the test, steering wheel is there are aligning torque and since the out-of-flatness on road surface is impacted
When, steering wheel can have a twisting resistance changed at random, can be prevented using the self-locking function of worm gearing at this time
Only steering wheel takes a turn for the worse and beats, and avoids the error in steering wheel angle test result, while motor being protected not damaged
It is bad.
The technical program is the steering assistance device for replacing driver to carry out accurate steering wheel manipulation in automobile test,
It can conveniently be installed, fixed form is can to carry out angle in the case where not changing test vehicle original structure
It adjusts, the visual field for not interfering tester and the in emergency circumstances escape space of tester, and the volume of whole device
It is small, light weight and cost is low.
In addition, the technical program is realized by control servo motor to steering wheel angle, turning velocity and steering frequency
It is precisely controlled, using worm and gear self-locking function, effectively prevent steering wheel during experimental test, because of wheel steering power mistake
The phenomenon that of taking a turn for the worse when big, avoid the error of test data.
The input of the technical program torque is inputted using Bowden cable, to reduce the matter of device suspension part
Amount reduces the automobile influence of the moment of inertia and shock loading to connection precision, intensity in the process of moving, to improve motor peace
The flexibility of dress avoids installing in motor and causes steering wheel the moment of inertia excessive on the steering wheel and damage.
This equipment can be effectively prevented steering wheel angle during the test and take a turn for the worse, and the test generated misses
Difference, and the torque of motor is effectively transferred to steering wheel, and can adapt to various sizes of steering wheel, it is quick and easy for installation.
