Abstract

The utility model discloses an exercise bike torsion tester. The exercise bike torsion tester comprises a machine frame, an exercise bike frame fixing base and a crank movement assembly, wherein the exercise bike frame fixing base is arranged on the machine frame; the crank movement assembly comprises a driving motor; a driving shaft of the driving motor synchronously drives a rotary encoder; the front end of the driving shaft of the driving motor is sleeved on a crank shaft of an exercise bike; a torsion sensor is also arranged on the driving shaft of the driving motor; and the rotary encoder and the torsion sensor are connected to a control box arranged on the machine frame. The crank shaft of the exercise bike is driven by the crank movement assembly to simulate the action of a user. Torsion or speed is transmitted to the control box through the torsion sensor. The control speed is detected and fed back through the rotary encoder, and the torsion or speed of the exercise bike is fully and automatically tested. An automatic test is adopted by the exercise bike torsion tester, so that compared with the exercise bike torsion tester which adopts a manually operated test, the exercise bike torsion tester is convenient to operate and high in test precision.

Description

Exercycle torsional test machine

Technical field

The utility model relates to the proving installation of body-building apparatus mechanical property, especially refers to a kind of proving installation that detects exercycle moment or speed.

Background technology

By the 6.1.4 in the 5th part in the EN957 standard chapters and sections " crank pedal class training device-additional specific safety requirement and test method " and 6.9 and 6.10 power, moment test request:

1. use speed or moment, or the measurement mechanism of speed and power, measuring error ± 2%.Driving through crank axle obtains energy, keeps constant airspeed during test as far as possible, and deviation is in ± 5%.

2. in rotating speed 60r/min ± 1 o'clock, the minimum drag distance when maximum gear is provided with, A level: lower extremity movement equipment 40N.M (about 250W), upper extremity exercise equipment 20N.M (about 125W)

3. in rotating speed 60r/min ± 1 o'clock, the minimum drag distance when maximum gear is provided with, B level: lower extremity movement equipment 28N.M (about 175W), upper extremity exercise equipment 14N.M (about 90W)

4. lower extremity movement equipment is in rotating speed 60r/min ± 1 o'clock, the maximum resistance distance of upper extremity exercise equipment when minimum gear is provided with in rotating speed 40r/min ± 1, A level: lower extremity movement equipment 8N.M (about 50W), upper extremity exercise equipment 6N.M (about 25W)

5. lower extremity movement equipment is in rotating speed 60r/min ± 1 o'clock, the maximum resistance distance of upper extremity exercise equipment when minimum gear is provided with in rotating speed 40r/min ± 1, B level: lower extremity movement equipment 13N.M (about 80W), upper extremity exercise equipment 9.5N.M (about 40W)

6. use above-mentioned testing apparatus; Setting the crank-motion equipment is permanent power mode (100 ± 5) W; Rotating speed 60r/min ± 1 is 0 with testing apparatus test and setting-up time (t), and changing rotating speed within maximum 5 seconds after the t=0 is (100 ± 1) W; T=0 measures power once more in the time of 15 seconds afterwards; And with show power ratio, performance number should be in 10% scope of t=0 time institute measured value, reduces rotating speed then and operates in 50 ± 2.5 more than repeating to 80r/min ± 1) W and 150 ± 7.5) two grades of W go up that repetitions are above to be tested.

What above-mentioned moment test was adopted usually is artificial method of operating, has the shortcoming that performance accuracy is poor, test error is big.

The utility model content

To the weak point that prior art exists, the utility model provides a kind of exercycle torsional test machine.This apparatus structure is simple, easy to operate, measuring accuracy is high.

For realizing above-mentioned purpose, the utility model technical scheme is:

Exercycle torsional test machine, this device comprises a frame, one is arranged at the exercycle vehicle frame holder on this frame; Also comprise a crank-motion assembly, it is arranged on the frame, comprises a CD-ROM drive motor, and the transmission shaft of this CD-ROM drive motor drives a rotary encoder synchronously; The front end socket exercycle crank axle place of this CD-ROM drive motor transmission shaft also is provided with a torsion torque sensor on this CD-ROM drive motor transmission shaft; Described rotary encoder is connected the control box that is arranged on the frame with torsion torque sensor.

The usefulness of technique scheme is:

The utility model drives exercycle crank axle place, anthropomorphic dummy's action through the crank-motion assembly.Send torsion or speed to control box through torsion torque sensor, detect and FEEDBACK CONTROL speed, automatically carry out the test of exercycle moment or speed through rotary encoder.The utility model adopts automatic test, compares with the manually-operated test, and easy to operate, measuring accuracy is high.
