Further improvement of the present invention is as follows：
Further, the displacement lever abuts setting with self-regulated arm.
Further, the servo motor work, shaft coupling drive transmission shaft to move right, and displacement sensor display reaches
It is stopped after distance to a declared goal.
Further, the gas chamber pushes self-regulated arm to be adjusted, and camshaft opens pushing rolling wheels and drives lever arm to two
Side is moved, and the first displacement sensor shows that the displacement of lever arm, second displacement sensor show the actuating length of gas chamber tappet, turns round
Force snesor shows the size of braking process torsion.
Further, it is drawn close to centre under the action of the thrust spring of the transmission shaft inside it, lever arm is driven to receive
Hold together, camshaft return.
Compared with prior art, the present invention has the beneficial effect that：The self-regulated arm detection of various models can be met；Can have
Effect detects practical brake clearance and reaches the inflation times in stable gap；It is i.e. detectable it is only necessary to replace individual parts；
Using pressurized cylinder and pressure gauge, the stable state under different air pressures can be clearly detected.The present invention has been applied to practice,
Former self-regulated arm and gas chamber stock up inspection without this time detection content, market happen occasionally brake side-slipping and gap can not be constant etc. quality
Feedback now increases self-regulated arm and the detection of gas chamber matching performance, which becomes the strong evidence of our company product qualification, and sieves
Unmatched self-regulated arm and gas chamber are selected, ensure that the constant of vehicle brake clearance.
