Course of work principle of the present invention is: by wheel-chair to be measured according to require in standard to carry out most steady state (SS) or least steady state (SS) regulate, and test is placed on wheel-chair with dummy according to standard-required, considering that the wheel braking of wheel-chair or wheel are not braked under two states is placed on the test platform that is horizontal according to its direction of tumbling, regulating wheel Wheel-chair makes the rotation of its angle of overturn parallel with test platform tilt axis, and error is ± 3 °.Then retrained and limited wheel Wheel-chair by fixing lock ring and turnover preventor structure, be used for preventing wheel-chair from rolling on inclined-plane or sliding when testing, but do not affect wheel-chair and freely rotate around wheel and the contact point of test surfaces and tumble or do not affect wheel-chair and freely to rotate around corresponding axle and tumble.Turnover preventor structure can the inclined degree of limited wheel Wheel-chair on test platform or distortion, but does not affect the stability of wheel-chair, and wheel-chair can be avoided to topple over backward because of out of trim.
When rotary handle, trap can along leading screw moving linearly, drive test platform to move with trap near one end of leading screw with this, the other end of test platform is then connected by a turning axle with base, makes freely to be rotated by turning axle between the test platform other end and base.When test platform one end is along leading screw rising or when declining, the other end and base keep rotating, and the angle formed between test platform and base just can be made to change, thus realize the adjustment of test platform bevel angle.Thus can the static rollover performance of testing wheel Wheel-chair under difference tumbles direction and steady state (SS).According to the requirement in testing standard, regulate test platform to horizontal level, wheel-chair is positioned on test platform according to direction of tumbling, and by fixing lock ring and turnover preventor structure, wheel-chair is limited, the bevel angle of test platform is regulated, until when all wheel-chair wheels of test platform rising end are zero to test platform pressure, determine the tip-over angle of test platform around turning axle, and give corresponding display by angular transducer and pressure transducer by data feedback, revision test, records repeatedly test result.Wherein be used for measuring the angular transducer of test platform and horizontal plane angle, measuring accuracy is ± 0.2 °.
To lean forward stability for testing wheel Wheel-chair, be placed in by test wheel-chair on the test platform 2 be horizontal, wheel-chair should towards the direction of dip plane descending.Make the line of two front axle parallel with test platform tilt axis (error ± 3 °), test is placed on wheel-chair with dummy's (meeting GB/T18029.11 to require).Wheel-chair wheel is not braked, makes it be in most steady state (SS).Fast pulley Wheel-chair is strengthened in the front end if needed can catching on wheel-chair vehicle frame by fixing lock ring 11, avoids wheel-chair to topple over backward because of out of trim.Rotary handle 4, the rear end of test platform 2 is driven to move up and down along leading screw 3 by trap 15, regulate the angle of inclination of test platform 2, until when the wheel-chair wheel of test platform rising end is zero to test platform pressure, determine the tip-over angle of test platform around turning axle, pressure transducer 9 is connected with angular display unit 14 with pressure display unit 13 by electric wire with angular transducer 10, platform stressing conditions and angle of inclination is shown in the display.Measure and record the angle of overturn, being rounded to 1 °, then test platform being reduced to horizontal level, terminate this test.
