Connecing, the left and right sides under table top is formed with raceway, and hydraulic cylinder is connected between support arm and chassis, and by the piston of hydraulic cylinder
The opening angle of two groups of interconnection support arms of bar extension and contraction control so that the parallel rise of table top or decentralization, in two sets of lifting frames
Hydraulic cylinder be connected respectively by two hydraulic oil pipes with same pedal hydraulic jack, realize lifting automobile or so simultaneously
The trailing wheel or front-wheel of both sides.
Both above-described lift racks can not be all realized in the lifting unpowered locking of peak, and take up an area face
Product is big, and the arrangement for being unfavorable for testing stand is laid, it is impossible to the use for coordinating anti-force type drum braking to test, can not realize multiaxle trucks
Load the test of braking ability.
Therefore, develop it is simple and reasonable, for axle lorry, by and fill the truck combination that axle semitrailer forms and load
Brake test bench, specification multiaxle trucks loading braking ability is come with this, it is ensured that it has more preferable safety and reliability, has been one
The extremely urgent task of item.

Test position of the wheel in Roller brake tester V proceeds by loading braking forces measuring；After first tested axletree detection,
Vehicle continues to move forward so that the second detected axle wheel for being detected vehicle is in the normal of Roller brake tester V
Test position, now No. 1 lifting mechanism I, No. 2 lifting mechanism II slowly drop to extreme lower position, No. 3 lifting mechanism III and No. 4
Lifting mechanism IV, which is failure to actuate, still keeps the extreme lower position of landing, and now first and the 3rd non-tested axletree wheel hanging, it is detected
The test position that the detected axle wheel of the second of measuring car is in Roller brake tester V proceeds by loading brake force inspection
Survey；After second tested axletree detection, vehicle continues to move forward so that be detected vehicle second is detected axle wheel
Normal test position in Roller brake tester V, No. 1 lifting mechanism I, No. 2 lifting mechanism II, which are failure to actuate, still to be kept lifting
Extreme lower position state is risen, but No. 3 lifting mechanism III and No. 4 lifting mechanism IV slowly give rise to extreme higher position, now first and the
Two non-tested axletree wheel hangings, the 3rd detected axle wheel for being detected vehicle are in the normal of Roller brake tester V
Test position proceeds by loading braking forces measuring；After 3rd tested axletree detection, No. 1 lifting mechanism I, No. 2 lifting machines
Structure II slowly gives rise to extreme higher position, and at this moment vehicle, which continues to move forward, leaves testing stand.
The operation principle of the lifting descent of the lifting device on wherein unpowered locking summit：The cylinder assembly of both sides
7 and Lifting air sac component C is inflated simultaneously so that the piston rod of cylinder assembly 7 drives the rocking arm 11 of both sides to be supported around rocking arm
Seat assembly 13 carries out outside rotation, so as to be slided with movable pulley 12 in guide rail square tube assembly 4 from Inside To Outside, reaches
To the state that compacting is contacted with caging bolt assembly 9, the line of the spindle central of contact point and rocking arm 11 with a vertical
Certain angle, whole rocking arm assembly 6 can be caused to be in stuck position, now need not be to Lifting air sac device C and cylinder
Assembly 7 is inflated, and platen 1 can also be in highest lift location, is kept stable and is not fallen.
Dropping process：The opposite direction of cylinder assembly 7 inflation of both sides, now the piston rod of cylinder assembly 7 inwardly pulls
The rocking arm 11 of both sides turns to the inside around rocker arm bearer assembly 13, so that with movable pulley 12 in guide rail square tube assembly 4
In from outside as interior Slideslip, reach the bottom surface of guide rail square tube 10 and rocker arm bearer 13 contact the extreme position of compacting, i.e.,
The extreme lower position of whereabouts.
While using this programme, I therein, No. 1 lifting mechanism, II, No. 2 lifting mechanisms, III, No. 3 lifting machines
Structure, IV, No. 4 lifting mechanisms, similarly it can reach same using a kind of elbow joint arm lifting device on unpowered locking summit
Effect.
