Abstract

本实用新型提出了支销式楔形制动器，包括制动底板、对称布置在制动底板上的左、右制动蹄、固定在底板上的双向扩张器、位于双向扩张器一端和支撑端设置有制动蹄回位弹簧，左、右制动蹄上通过铆钉铆接有摩擦片，左、右制动蹄的支撑端是外圆弧，底板上的凸台两端设有内圆弧，与左、右制动蹄的支撑端的外圆弧分别与制动底板上的内圆弧配合，制动蹄只能绕支底板上的凸台内圆弧转动，不能左右串动。在制动蹄两侧增加有扇形加强筋。制动蹄的支撑端通过外圆弧与制动底板内圆弧配合，保证制动蹄与制动底板可靠连接、转动灵活、制动性能高、结构紧凑、制动间隙自动调整(也可手调间隙)，消除制动蹄拖磨现象。在制动蹄两侧增加有扇形加强筋，可提高制动蹄的强度。

Description

支销式楔形制动器
技术领域
本实用新型涉及一种支销式楔形制动器。 
背景技术
目前，浮式增力楔形制动器，其结构是采用了浮式双增力式制动器。是由固定在制动底板上的一个双向扩张器和一个增力式扩张器，由双向扩张器推动制动蹄涨开进行制动。在使用时，因领蹄在制动时出现回位不及时，存在拖磨现象，造成制动鼓发热、制动器抱死的问题。 
发明内容
本实用新型的目的在于提供一种支销式楔形制动器，既提高了制动性能，又保证了制动蹄与制动底板可靠连接，消除制动蹄拖磨现象。 
本实用新型的技术方案为：支销式楔形制动器，包括制动底板、对称布置在制动底板上的左、右制动蹄、固定在底板上的双向扩张器、位于双向扩张器一端和支撑端设置有制动蹄回位弹簧，左、右制动蹄上通过铆钉铆接有摩擦片，其特征在于：左、右制动蹄的支撑端是外圆弧，底板上的凸台两端设有内圆弧，与左、右制动蹄的支撑端的外圆弧分别与制动底板上的内圆弧配合，制动蹄只能绕支底板上的凸台内圆弧转动，不能左右串动。 
为防止制动蹄在使用过程中受力变形，发生制动器抱死现象，在制动蹄两侧增加有扇形加强筋。 
有益效果：制动蹄的支撑端通过外圆弧与制动底板内圆弧配合，保证制动蹄与制动底板可靠连接、转动灵活、制动性能高、结构紧凑、制动间隙自动调整(也可手调间隙)，使制动鼓和蹄片保证精确的制动间隙，消除制动蹄拖磨现象，并且维修拆卸方便。在制动蹄两侧增加有扇形加强筋，可提高制动蹄的强度。 
附图说明
图1是本实用新型的主视图。 
图2是图1中制动蹄的结构示意图。 
具体实施方式
如图1所示的支销式楔形制动器，包括制动底板1、对称布置在制动底板上的左、右制动蹄2、固定在底板上的双向扩张器3、位于双向扩张器一端和支撑端设置有制动蹄回位弹簧4，左、右制动蹄上通过铆钉铆接有摩擦片5，左、右制动蹄的支撑端是外圆弧6，制动底板1上的凸台两端设有内圆弧与左、右制动蹄的支撑端的外圆弧6分别与制动底板上的内圆弧配合；左、右制动蹄2的轴向通过圆柱销7限位，避免左右串动。 
如图2所示的制动蹄，在制动蹄2两侧增加有扇形加强筋8可提高制动蹄的强度，防止制动蹄在使用过程中受力变形，发生制动器抱死现象。
