Description
Technical field
The present invention relates to a kind of axletree installation system, it enables the frequency of axletree movable joint in required value, and living
The value of the Frequency Index of section correctly and can be adjusted accurately.
Background technology
In many motor vehicles, in front axle and knuckle assembly, using pad, pad described two parts it
Between provide frictional force and its be assemblied in the gap of package.It is named as the thick axle of centrepin from pad, axletree and knuckle
Middle part pass through.By this pin, expected rotary motion of the knuckle around axletree can be realized.Meanwhile, pad is by turning to
Expected frictional force is realized between section and axletree and prevents the reaction of steering wheel extremely sensitive or extremely heavy.
Frictional force between knuckle and axletree is measured respectively for all of axletree, and suitable pad according to
The result of test determines.After pad is determined, suitable pad shrinks and is assemblied in the gap between axletree and knuckle.
In the motor vehicle, the adjustment for carrying out the frequency of axletree movable joint is extremely important.Especially, the movable joint frequency of front axle
Rate adjustment largely directly affects reaction and the quality of steering wheel system.Technically, each vehicle should be provided really
Fixed movable joint Frequency Index value, each measurement parameter in assembly line correctly and should be adjusted accurately, and assembling process
Should to prevent measure error in the way of realizing.
In assembly line, it is typically via dynamometer reality according to the adjustment of determination and expectation index to front truck axle joint frequency
Existing.The measured value obtained via dynamometer is not accurate enough and reliable.
In prior art, some apply the measurement with regard to spacer thickness, and such as knuckle, pad and front axle
Part between distance measurement.
In the background of the invention the U.S. Patent Publication Document of numbering US6622397 (B1) measurement spacer thickness is sent out
It is bright.In this invention, in order to measure movable joint part used in gasket part thickness, used between two bearings away from
From.The range measurement stayed between two bearings according to the load formed on device is the thickness of pad.
In the patent document, undisclosed for example in detail storage will group with regard to each information for assembling and automatic storage
The feature of the assembling value (such as spacing) of each part of dress.Undisclosed package system, it passes through to move along not coaxial line
Laser and thickness measure sensor carry out the measurement of gap and thickness, and it automatically selects pad.
In background in the present invention in the Chinese utility model document of numbering CN202701910 (U), disclose by swashing
Photo measure carries out the invention of the restriction of the distance between part.In this invention, thus equipment can be sensed by laser distance
Device determines workpiece on axle position relative to each other.Meanwhile, via feature is wirelessly transferred, the data can be common from different points
Enjoy.
In the patent document, undisclosed for example in detail storage will group with regard to each information for assembling and automatic storage
The feature of the assembling value (such as spacing) of each part of dress.Undisclosed package system, it passes through to move along not coaxial line
Laser and thickness measure sensor carry out the measurement of gap and thickness, and it automatically selects pad.
In background of the present invention in the Chinese patent application file of numbering CN103245298 (A), disclose and be designed to
Measure the invention of the circular gap in axle joint connection.In the invention, the laser sensor on the equipment is immediately
The change of distance between the mobile movable joint of measurement and fixing link.In this way, in the component of axle and movable joint, this distance
Difference rapidly and can be accurately measured.
In the patent document, undisclosed for example in detail storage will group with regard to each information for assembling and automatic storage
The feature of the assembling value (such as spacing) of each part of dress.Undisclosed package system, it passes through to move along not coaxial line
