Description
Technical field
Car steering linkage mechanism loads the detection method in gap, is that steering gear is applied by automobile steering roller
Larger active force, quantitatively detects that steering gear loads a kind of method in gap, belongs to car consumption credit method and technology
Field.
Background technology
The prior art method that quantitatively detection car steering linkage mechanism does not load gap, with following deficiency
Place:(1) automobile stops being scheduled on level land, the method that slack of the steering wheel is quantitatively detected using steering force-angle measuring instrument, simply
The free clearance of steering gear and the part free clearance of steering gear are have detected, due to the steering resistance of deflecting roller on the ground
Power is little, it is impossible to detect the loading gap of steering gear.(2) using vehicle original place larger angle left and right turn, due to right
Less, some gaps of steering gear heavy wear and failure are difficult to display steering gear active force, and
Detection loading gap can not be quantified.(3) existing chassis clearance instrument equipment be hydraulic drive carrying deflecting roller flat board before and after, it is left
Right rectilinear movement, does not measure the sensor and method in steering gear gap, simply a kind of to apply active force to deflecting roller
Auxiliary equipment, if loading effect power and stroke are excessive, for irreversible steering device, it is possible to damage steering gear.
To overcome the deficiencies in the prior art, the detection method in gap is loaded using car steering linkage mechanism, by turning to driver
Structure applies larger active force, and loading quantitatively detects the gap of steering gear, improves the travel safety of automotive steering.
The content of the invention
The reliability of car steering linkage mechanism is one of important performance of vehicle safety travel, when steering gear
It is prior to influence the reliable of steering gear in addition to it can reduce the sensitiveness of steering-effecting when loading gap is excessive
Property, once bindiny mechanism comes off, it will cause serious traffic safety accident.The abrasion of steering gear and failure are special
Putting is:Only in the state of compared with noticeable effort, it can just be reflected in the form of increasing gap, so, by detecting automobile
Steering gear loads gap, determines abrasion and the failure of steering gear, improves the sensitiveness and reliability of steering system.
The principle of detection method in car steering linkage mechanism loading gap is:Steering spindle one side deflecting roller stops being scheduled on coarse
On cement level land or surface is covered with the level land of diamond dust, attachment coefficient of the wheel on level land is more than or equal to 0.7, and another side turns
Stop to be scheduled on the slide plate on level land to wheel, slide plate can install one along the direction linear slide perpendicular with direction of traffic on slide plate
Individual displacement transducer or a Length Indication scale are to measure the displacement of slide plate, and the attachment coefficient of sled surface and wheel is little
, can be using artificial or motor or hydraulic-driven slide plate in 0.6.Engine misses, first to a direction moving slide board, reduce and turn to
Transmission mechanism is after the free clearance of the direction, and with slide plate is continued to move to, the active force suffered by steering gear is more next
Bigger, when the active force suffered by steering gear is equal to the force of sliding friction of deflecting roller on slide plate, the deflecting roller is in cunning
Occur the critical localisation that will be slided on plate, stop the sledge displacement amount of moving slide board, detection and record critical slip circle position, by
In different with the attachment coefficient on slide plate on level land, and same axle left and right turn wheel is more or less the same again, so, stop being scheduled on level land
The lateral sliding frictional force of deflecting roller is relatively larger than deflecting roller on the lateral sliding frictional force of deflecting roller on slide plate, level land and does not produce cunning
It is dynamic.Then opposite direction moving slide board, similarly, when the active force suffered by steering gear is equal to the lateral of deflecting roller on slide plate
During force of sliding friction, there is the critical localisation that opposite direction will be slided in the deflecting roller, and stops moving slide board, detection and record negative side
To the sledge displacement amount of critical slip circle position, the sledge displacement amount between both direction critical slip circle position is equal to turn to transmission
Mechanism loads gap.
Due to the positive drive efficiency high of reversible steering gear, inverse transmission efficiency is also high, active force can for delivery to steering wheel,
Deflecting roller on slide plate may not be moved, and active force makes steering wheel rotation after eliminating the whole gaps of steering gear, at this moment should
The critical rotation position that will be rotated with steering wheel is sampled, the sledge displacement surveyed between both direction critical rotation position
Amount is steering gear loading gap.Most of existing automobile steering device is half reversible steering gear, positive drive efficiency high,
Inverse transmission efficiency is low, can reach steering wheel from steering gear anti-pass compared with noticeable effort, may there is two kinds of situations, a kind of
It is the critical slip circle position sample that will be slided with deflecting roller, another is that the critical rotation position that will be rotated with steering wheel takes
Sample, so the critical localisation of deflecting roller and steering wheel is observed, first to there is critical localisation sampling.Turned to for unidirectional type
Device, inverse transmission efficiency is zero, and active force can not be delivered to steering wheel, and steering wheel will not be rotated, and can only will be slided with deflecting roller
Critical slip circle position sample.
Deflecting roller is much larger than steering drag on ground and the lateral sliding resistance on slide plate, and steering gear is applied
Active force not only be relatively larger than normal vehicle operation active force, the active force that also relatively larger than vehicle is turned on the spot, compared with your writing
With can effective eliminating machine gap under force intensity.The lateral sliding resistance produced using deflecting roller deadweight, vehicle is bigger to be turned to
The lateral sliding resistance that wheel deadweight is produced is bigger, meets the Intensity Design of vehicle steering system, will not damage or damage steering system machine
Structure.
Car steering linkage mechanism loads the detection method in gap, is that quantitatively detection steering gear adds by loading
Gap is carried to check a kind of method of abrasion and failure, it is characterised in that:Steering spindle one side deflecting roller stops being scheduled on attachment coefficient big
In on the level land equal to 0.7, another side deflecting roller stops being scheduled on can be along the ground of the direction linear slide perpendicular with direction of traffic
On slide plate, the glide direction on slide plate installs a displacement transducer or a Length Indication scale to measure slide plate slides
Displacement, attachment coefficient of the deflecting roller in sled surface is not more than 0.6, can be using artificial or motor or hydraulic-driven come slow
Moving slide board;Engine misses, to a slow moving slide board in direction, the active force suffered by steering gear is increasingly
Greatly, until deflecting roller will be slided on slide plate or steering wheel will be rotated, moving slide board, detection and the record direction are stopped
Deflecting roller critical slip circle position or the sledge displacement amount of steering wheel critical rotation position, similarly, the slow moving slide board of opposite direction,
Until deflecting roller will be slided on slide plate or steering wheel will be rotated, stop moving slide board, detection and record opposite direction turn
To the sledge displacement amount of wheel critical slip circle position or steering wheel critical rotation position, both direction deflecting roller critical slip circle position
Between or steering wheel critical rotation position between sledge displacement amount be equal to car steering linkage mechanism loading gap.
Embodiment
Illustrate the specific implementation of the detection method in car steering linkage mechanism loading gap exemplified by detecting a lorry
Mode, the vehicle is anti-reversible steering gear.

Wheel is more than 0.7 with the attachment coefficient on level land surface, and another side deflecting roller stops being scheduled on slide plate, slide plate be arranged on level land can along with
The perpendicular direction linear slide of direction of traffic, the glide direction on slide plate installs a displacement transducer or a length refers to
Indicating chi to measure the displacement of slide plate slides, sled surface is smooth steel plate, and the attachment coefficient of deflecting roller and smooth steel plate is small
In 0.6, slide plate is equipped with screw rod transmission pair, using the slow rotary screw rod driving slide plate rectilinear movement of motor reducer.
Engine misses, first to a direction moving slide board, reduce steering gear after the free clearance of the direction,
With slide plate is continued to move to, the active force suffered by steering gear is increasing, when the work suffered by steering gear
When being firmly equal to the force of sliding friction of deflecting roller on slide plate, the deflecting roller reaches the critical localisation that will be slided, and stops mobile sliding
The sledge displacement amount of plate, detection and record critical slip circle position.Then, opposite direction moving slide board, similarly, the deflecting roller reach by
The sledge displacement amount of the critical localisation to be slided, detection and record opposite direction critical slip circle position, both direction critical slip circle position
Sledge displacement amount between putting is equal to car steering linkage mechanism loading gap.
Car steering linkage mechanism loads the detection method in gap, applies larger active force to steering gear, fixed
Amount checks the wear extent and failure of steering gear, has the advantages that accuracy is good, simple in construction, easy to operate.
