轮式装载机的钳盘式制动器(如图1所示)工作状况恶劣,活塞外露部分锈蚀或被油污污染很难自动回位,应及时停车修理,否则机器行驶困难,制动盘温升很高。活塞缸2、4为盲孔结构,修理时很难从缸中取出活塞。为此,在ZL40、ZL50装载机制动器维修时,我们在近于缸中心处即图1B处开一个M10至M12的螺孔,便可由此用铁棒将活塞轻易打出,进行维修保养。修装完后,再用一约10mm长的螺钉密封所开螺孔,杜绝渗漏油液。 Wheel loader jaw disc brake (Figure 1) poor working conditions, the piston exposed part of the rust or oil pollution is difficult to automatically return, parking should be promptly repaired, or the machine difficult to drive, the brake disc temperature rise is very high. Piston cylinder 2,4 for the blind hole structure, it is difficult to remove the piston from the cylinder repair. To this end, ZL40, ZL50 loader brake repair, we are in the center of the cylinder near the center of FIG. 1B to open a M10 to M12 screw hole, which will be able to use the iron rod piston easily hit for maintenance. After repair, and then use a screw about 10mm long hole opened to prevent leakage of oil.
