Description
Technical field
The utility model relates to a kind of bicycle accessories device for detecting performance, particularly relates to a kind of Bicycle dished brake braking distance test macro.
Background technology
Through the development of nearly 200 years, bicycle, from being luxury goods at first, to walking-replacing tool, then becoming the vehicles of multi items till now, just like in the life of people, serves vital role.The requirement of people to it is also more and more higher, just meets from initial having, handy to requiring, then requires that it has accurate performance till now.Bicycle brake as one of bicycle important performance also stops from the V steel ring, the lock that rises on axle, and develops into present disc brake.There is strict requirement to the braking quality of bicycle at home with in the bicycle standard in Europe, and propose actual road test and testing machine test two kinds of method of testings for braking quality test.Find by inquiry, the producer of domestic production and design disc brake, generally all can adopt the method for actual road test when testing product, but does not carry out according to the requirement in European standard during test.On the bicycle being used for testing, not installation rate table, the device etc. of recording distance, to the judge of braking quality entirely with the subjective judgement of tester.
Researching and developing and producing in the process of Bicycle dished brake, need to test its product according to safety standard, to ensure the up-to-standard of product.At present, the test of the braking distance of Bicycle dished brake is mainly tested by bike by tester, and this method of testing exists a lot of defect: tester judges Bicycle dished brake quality with subjective consciousness entirely on the one hand, and randomness is large; On the other hand, in the development of disc brake, tester directly tests by bike, may cause the accidents such as tumble injury.
Summary of the invention
The utility model provides a kind of Bicycle dished brake braking distance test macro, and this Bicycle dished brake braking distance test macro can measure the braking distance of bicycle more exactly, solves the accurate test problems of the dynamic properties such as brake, life-span.
The utility model solves the technical scheme that its technical matters adopts: a kind of Bicycle dished brake braking distance test macro, comprises frequency converter, motor, clutch coupling, inertia disk, disc, the code-disc that tests the speed, braking clamp, device for testing tensile force, operating grip;
Described frequency converter is connected with motor by frequency conversion line; Motor is connected as a single entity by rotation axis and inertia disk, is provided with clutch coupling between motor and inertia disk; Disc is connected with inertia disk by rotation axis; Disc side is provided with the code-disc that tests the speed; Braking clamp is clipped in disc both sides, is connected with operating grip by brake cable.
Device for testing tensile force is provided with between described braking clamp and operating grip; Thus can accurate calculation go out operating grip hold lock power.
Described motor adopts threephase asynchronous machine; Can, by regulating the output frequency of frequency converter, the rotating speed of motor be changed, and then regulate the speed of analogue means.
Described frequency converter is provided with RS485 communication interface, and user can be connected with host computer by RS485/RS232 converter, and then is set by the running parameter of host computer to frequency converter.
Brake rubber block is provided with in described braking clamp; The friction with the disc of vehicle wheel rotation can be increased, thus by friction force, disc velocity of rotation is reduced.
The utility model, a kind of Bicycle dished brake braking distance test macro, motor drives whole inertia disk to rotate, and is controlled motor speed by frequency converter, is adjusted to the travel speed of analog bicycle; Clutch coupling act as when inertia disk is adjusted to setting speed, depart from motor rotation axis; The code-disc that tests the speed carries out real-time testing the speed to inertia disk; Operating grip is connected with braking clamp by brake cable, and when needs are braked, depression handle makes whole inertia disk brake; Install pulling force sensor at brake cable place, determine the point of application of handlebar, according to the mechanical structure of handlebar, the pulling force of known brake cable is 2 times of the lock power of holding that handlebar place is subject to; Thus draw measure handlebar place hold lock power.
A kind of Bicycle dished brake braking distance of the utility model test macro, its beneficial effect is:
1) Bicycle dished brake braking distance test macro can realize the follow-on test of braking procedure automatically, thus can average to repeatedly braking distance and obtain the braking distance of disc brake apparatus.
2) Bicycle dished brake braking distance test macro stable performance, simple to operation, practical, there is good actual application value.
