W100_2~1挖掘机行走制动器(图1)系常闭式。在弹簧13的作用下,通过压杆10与下端连接叉子7、拉杆6带动短连杆4和长连杆5摆动。正转时,下半闸带3耳环靠在固定托架14凹槽下平面上并使上半闸带15耳板靠近,夹角α变小,闸带抱紧制动轮,挖掘机停止前进;反转时,上半半闸带15耳板靠在固定托架14凹槽上平面,同样实现制动。支承螺钉9用来限制耳环的活动范围,使不超过死点。调整螺钉9时,应使制动闸带下耳环距死点10～15毫米,夹角α不 The W100_2~1 excavator travel brake (Fig. 1) is normally closed. Under the action of the spring 13, the fork 7 is connected to the lower end by the pressing rod 10, and the short rod 4 and the long rod 5 are driven by the rod 6 to swing. In the forward rotation, the lower half brake band 3 earrings rests on the lower plane of the groove of the fixing bracket 14 and makes the upper half brake band 15 lug plate approach, the included angle α becomes smaller, the brake band holds the brake wheel, and the excavator stops moving forward When reversing, the upper half of the brake band 15 lugs against the upper plane of the groove of the fixed bracket 14, and braking is also achieved. Support screws 9 are used to limit the range of movement of the earrings so that they do not exceed the dead point. When adjusting the screw 9, the brake should be put under the earring 10 ~ 15 mm from the dead point, the angle α is not
