Hand of the utility model hydraulic motorcycle brake system rigidity test frock in test hydraulic motorcycle brake system
During handle master cylinder rigidity, rack body is connected with braking handle of motorcycles, rotates push rod by hand, make free end and the handle of push rod
The outer face of main cylinder piston-rod offsets, and constantly rotates push rod, makes the free end continued compression handle main cylinder piston-rod of push rod,
And linear displacement transducer constantly detects the shift value after record handle main cylinder piston-rod is compressed, meanwhile, pressure sensor prison
Changing value of the pressure surveyed in handle master cylinder when compression displacement occurs for handle main cylinder piston-rod, until handle main cylinder piston-rod pressure
Range is reduced to, namely linear displacement transducer recorded the maximum that compression displacement occurs for handle main cylinder piston-rod, so
Completion is once tested, and the shift value that tester compresses according to the handle main cylinder piston-rod that recorded is converted into handle master cylinder internal pressure
Pressure value draws out pressure in the changing value of contracting volume, the changing value of the handle master cylinder inner volume and corresponding handle master cylinder
Power and compression volume change curve, and slope of a curve is obtained, namely the rigidity of handle master cylinder；Test more than repeating three times, divides
Slope of a curve is not obtained, then draws average value, you can draws the rigidity of handle master cylinder, its measuring accuracy is higher.
The test data of the utility model hydraulic motorcycle brake system rigidity test frock is as follows：
In testing for the first time, the displacement after record handle main cylinder piston-rod is compressed constantly is detected by linear displacement transducer
Changing value of the pressure when compression displacement occurs for handle main cylinder piston-rod in value and pressure sensor monitoring handle master cylinder,
And the changing value of compression volume corresponds to pass in the handle master cylinder of the shift value conversion after being compressed according to handle main cylinder piston-rod
It is as shown in the table：
Table one：
With compressing Volume Changes curve in handle master cylinder, obtaining slope is for the main in-cylinder pressure change of handle drawn by table one
22.6MM3/ bar, namely show that hydraulic motorcycle brake system rigidity is 22.6MM3/bar。
Similarly, carry out second to test, test data is as follows：
Table two：
With compressing Volume Changes curve in handle master cylinder, obtaining slope is for the main in-cylinder pressure change of handle drawn by table two
22.89MM3/ bar, namely show that hydraulic motorcycle brake system rigidity is 22.89MM3/bar。
Similarly, third time test is carried out, test data is as follows：
Table three：
With compressing Volume Changes curve in handle master cylinder, obtaining slope is for the main in-cylinder pressure change of handle drawn by table three
22.27MM 3/ bar, namely show that hydraulic motorcycle brake system rigidity is 22.27MM3/bar。
In summary, test show that hydraulic motorcycle brake system rigidity is followed successively by three times：22.6MM3/bar、
22.89MM3/bar、22.27MM 3/ bar, therefore test three times can be calculated and draw the flat of hydraulic motorcycle brake system rigidity
