Before test, when namely vehicle does not sail into, No. 1 lifting mechanism I of heavy multiaxle trucks heavy duty reproduction formula braking performance test test unit, No. 2 lifting mechanism II, No. 3 lifting mechanism III and No. 4 lifting mechanism IV are all in the most high state of lifting, concordant with ground above, tested vehicle sails testing table into until when the first tested axle wheel of tested vehicle stablizes the normal detection position being in Roller brake tester V, start the damping force of the loaded condition detecting the first tested axletree, now No. 1 lifting mechanism I, No. 2 lifting mechanism II are failure to actuate and still keep lifting extreme higher position state, but No. 3 lifting mechanism III and No. 4 lifting mechanism IV drop to extreme lower position slowly, now the two or three non-tested axle wheel is unsettled, the detection position that first detected axle wheel of detected vehicle is in Roller brake tester V starts to carry out loading braking forces measuring, after first tested axletree detects, vehicle continues to move forward, second of detected vehicle the detected axle wheel is made to be in the normal detection position of Roller brake tester V, now No. 1 lifting mechanism I, No. 2 lifting mechanism II drop to extreme lower position slowly, No. 3 lifting mechanism III and No. 4 lifting mechanism IV are failure to actuate and still keep the extreme lower position of landing, now first and the 3rd non-tested axletree wheel hanging, the detection position that the second detected axle wheel of detected vehicle is in Roller brake tester V starts to carry out loading braking forces measuring, after second tested axletree detects, vehicle continues to move forward, second of detected vehicle the detected axle wheel is made to be in the normal detection position of Roller brake tester V, No. 1 lifting mechanism I, No. 2 lifting mechanism II are failure to actuate and still keep lifting extreme lower position state, but No. 3 lifting mechanism III and No. 4 lifting mechanism IV give rise to extreme higher position slowly, now the first and second non-tested axletree wheel hangings, the normal detection position that the 3rd detected axle wheel of detected vehicle is in Roller brake tester V starts to carry out loading braking forces measuring, after 3rd tested axletree detects, No. 1 lifting mechanism I, No. 2 lifting mechanism II give rise to extreme higher position slowly, and at this moment vehicle continues to move forward and leaves testing table.
The wherein principle of work of the lifting descent of the lifting device on unpowered locking summit: cylinder assembly 7 and the Lifting air sac assembly C of both sides inflate simultaneously, the piston rod of cylinder assembly 7 is made to drive the rocking arm 11 of both sides to carry out outside rotation around rocker arm bearer assembly 13, thus band travelling block 12 slides from Inside To Outside in guide rail square tube assembly 4, reach the state contacting compacting with caging bolt assembly 9, line and the vertical direction of the spindle central of contact point and rocking arm 11 are angled, whole rocking arm assembly 6 can be made to be in stuck position, now do not need to inflate Lifting air sac device C and cylinder assembly 7, platen 1 also can be in the highest lift location, keep stable not fall.
Dropping process: cylinder assembly 7 inflation in the other direction of both sides, now the piston rod of cylinder assembly 7 inwardly pulls the rocking arm 11 of both sides to turn to the inside around rocker arm bearer assembly 13, thus band travelling block 12 in guide rail square tube assembly 4 from outside as inner slide, the bottom surface reaching guide rail square tube 11 contacts the extreme position of compacting, the extreme lower position namely fallen with rocker arm bearer 13.
