After the completion of enter detection control model, control system is automatically into vehicle monitoring state；
(2) tested vehicle is according to prompting, honest traveling placed in the middle, by wheel be placed in drive roll 10 and follower rollers 16 it
Between, variator is placed in neutral, loosens the brake；
(3) vehicle tyre blocks the photoswitch that puts in place, and display screen prompting vehicle puts in place, according to the testing process of software set,
Load lifting mechanism to lift brake detection table detector unit, reach when meeting gb21861 regulation halt condition, stop lifting simultaneously
Measure the axle load built under axle the present situation of this tested vehicle；
(4), after measuring axle load, clamping body, by brake detection table 2 clamping, then starts the motor of driving means, cylinder group
Rotation, starts to sample and keep enough sampling times after stablizing several seconds, and the meansigma methodss measuring sampling process, as drag, are examined
The brake pedal force specifying when brake pedal is gradually floored by the person of testing by display screen instruction or braking ability of stepping on checks, records
Left and right wheel braking force increases the numerical value of overall process and left and right wheel maximum braking force, tests each axletree successively, to parking system
Moving axis, manipulates parking brake control device, records parking braking power numerical value.Calculate braking ratio, the left and right wheels brake force of each axletree
Difference percentage ratio, car load braking ratio, parking braking power percentage ratio；
(5) unclamp clamping body, then fall brake detection table, detection terminates, lamp screen prompting vehicle rolls detection zone away from.
The tested axle of tested vehicle is elevated by this utility model by loading lifting mechanism, is increased tested by axle load transfer
The axle weight of axle, when simulated automotive loads, the load condition of this detection axle, can measure the loading braking ability of each axletree successively.Warp
Cross test of many times, the automobile brake perfrmance detection means that this utility model provides, to multiaxis lorry and and axle trailer can be filled enter
Row lifting loads braking performance test, and predominantly detecting object is commercial car, can truly detect the maximum braking force of automobile, detection effect
Rate is high, increased vehicle driving safety coefficient.
