Working principle of the present invention:
As shown in Figure 1, be the present invention at brake clearance release position figure just often, i.e. home position figure during entrucking, at this moment, adjust screw head and front clutch engagement and with back clutch separation, unit brake cylinder length is L.
As shown in Figure 4, when brake shoe and the normal brake application of wheel gap, pressurized air from distributing valve enters the cup leather right side through the base on the cylinder body, pressurized air promotes whole piston assembly and moves along the direction of compression release spring, this can make adjusts the whole reach of nut portion, contact with limited ring up to bearing cup, piston assembly continues to be moved to the left, the adjusting play reduces, the adjustment screw head separates with front clutch and meshes with the back clutch, this moment, brake shoe should just in time touch wheel, and wheel is applied braking force.The distance that adjustment nut drive adjustment sleeve stretches out the pillar head is command range A, and brake slack adjuster is not adjusted, and at this moment, the unit brake cylinder length overall is L+A; After waiting to alleviate, whole piston assembly withdrawal namely returns to position among Fig. 1, and the unit brake cylinder length overall still is L.
As shown in Figure 5, when brake shoe and wheel wear, namely when brake shoe and the increase of wheel gap, during braking, adjusting nut displacement distance can be greater than command range A.When bearing cup contacts with limited ring, piston assembly continues to move forward under the pressure air effect, because the restriction of limited ring and the existence of adjusting play, so holddown spring is compressed, piston continues to move forward, simultaneously, the front clutch that is fixed on the piston also moves with piston forward, the adjusting play reduces, at this moment, because adjusting screw rod is connected with bearing cup by rolling bearing, so adjust screw rod bearing cup with can not move forward after limited ring contacts, therefore, adjustment screw head and the front clutch of adjusting screw rod break away from (because brake shoe does not also touch wheel, adjust screw head and neither be meshed with front clutch this moment, be not meshed with the back clutch) yet, under the tension force effect of adjusting spring, the adjustment screw rod rotates motion but does not produce movement in the axial direction, thereby make and adjust the adjustment nut that screw flight is connected and extend left, after brake shoe touches wheel and applies normal brake application power, adjust screw head and back clutch engagement, the adjustment screw rod stops operating, adjust nut and also stop elongation, at this moment, adjust nut and stretch out corresponding adjustment distance B along adjusting screw axial.The distance that adjustment nut drive adjustment sleeve stretches out the pillar head is A+D, and at this moment, the unit brake cylinder length overall is L+A+D; After waiting to alleviate, the withdrawal of whole piston assembly namely returns to position among Fig. 6, adjust screw head and front clutch engagement and with back clutch separation, the unit brake cylinder length overall becomes L+D.
When changing brake shoe or wanting to shorten unit brake cylinder, apply active force in unit brake cylinder left side (adjustment nut end), make and adjust screw head and front clutch disengagement, spring is adjusted in compression simultaneously, the position of adjustment nut on screw rod moved right, and unit brake cylinder length overall L shortens.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
