PC control bicycle disc brake and front fork disc brake fatigue testing machine WSD-8706A
First, the test principle: the simulated bicycle in the actual riding process, the rider uses the brake to control the speed and parking, the brake grip force will be transmitted through the brake to the brake fixed seat on the frame and the front fork, the brake fixed seat on the frame and the front fork will continue to bear external force. The quality of the brake is related to the safety of the driving, so the quality of the brake fixed seat is related to the safety and convenience of the whole car. The testing machine is designed according to ISO 4210 related standards, the whole test system is automatically controlled by PLC, the force application system adopts force closed-loop control, when the test force applied to the brake fixed seat reaches the set force, the automatic return. After a certain number of loads, it is detected for damage. Provide test data for manufacturers to evaluate the advantages and disadvantages of products and technical improvements
2, according to the standard: ISO 4210
Iii. Test method:
(1) Frame disc brake test
1) During the test, the frame is fixed on the test machine in accordance with the method specified in the standard, and the position of the front and back of the dummy five-way shaft can be manually adjusted to adapt to the size of the frame
2) Fix the rear hook claw of the frame on the rotating false rear axle, adjust the height of the false five shafts, so that the state of the frame is the same as the actual riding
3) Adjust the Angle and height position of the loading cylinder to meet the standard requirements
4) Fix an adjustable part to prevent loosening during the test and affect the test
5) Set the test force value and number of test requirements on the computer
6) Adjust the maximum deformation allowed by the test, and the machine will automatically stop the test after exceeding this deformation
7) Start the test procedure to start the test, the test reaches the set number or the specimen is damaged, the machine will automatically stop the test and retain the test results
(2) Front fork disc brake test
1) During the test, the front fork assembly is fixed on the test machine in accordance with the standard method, and the height position of the front fork can be manually adjusted to adapt to the position of the loading cylinder;
2) Fix the front fork assembly on the special fixture, adjust the left and right position of the loading cylinder, so that the loading fixture can be just assembled on the front fork, and fix all parts.
3) Set the test force value and number of test requirements on the computer.
4) Adjust the maximum allowable deformation of the front fork, and the machine will automatically stop the test after exceeding this deformation;
5) Start the test procedure to start the test, the test reaches the set number or the specimen is damaged, the machine will automatically stop the test and retain the test results.

10) Loading mode: pneumatic loading
11) Database function: automatically record each measurement result to facilitate analysis and provide evidence
12) Shutdown mode: The test piece breaks the system or automatically stops beyond the displacement
13) Equipped with special test five-way fixture, can adjust the position up and down, before and after, increase the thread locking, fixed firmly, good rigidity.
14) Equipped with false frame front tube, in line with standard test requirements. During the test, it is fitted with the first bowl group.
15) Equipped with special test frame disc brake fixed seat test fixture. Can support a variety of conventional frame.
16) Adjust the position of the locking screw selection of quick disassembly, easy to operate, adjust the position using the lead screw adjustment.
17) With pressure regulating tank, better stable working pressure, so that the loading force is more stable.
18) Pneumatic components brand: Japan SMC or Germany FESTO
19) Shutdown conditions: low gas supply pressure stop, large deformation of the specimen, cylinder stroke exceeds the set value stop
20) Equipped with independent electric control box
21) Power supply: 220V 5A
22) Air source: pressure 0.7MPa gas flow 200L/MIN
23) The main body of the machine is a steel component, high strength, not easy to deformation
24) The base of the machine is solid steel, with good stability, equipped with reinforcing bars and water transfer feet
25) Electrostatic spraying of machine appearance, electroplating of other parts, high rust prevention ability, beautiful appearance
