Description

一种制动机构 技术领域
本发明属于制动机构技术领域，尤其涉及一种发热较小的制动机构。
背景技术
制动机构用于诸多领域，最主要的是汽车领域，目前汽车制动中一般有两种，一种为鼓式刹车制动，另一种为盘式刹车制动，鼓式刹车制动缺点是在制动过程中发热较为严重，汽车在下长坡的时候需要长时间刹车制动，这样刹车片发热严重制动距离变长或刹车失灵常有发生；盘式刹车由于裸露在外，其散热效果会好于鼓式刹车制动，但是其结构过于复杂、成本较高，并且其在夏天的时候同样会受到刹车盘高温的较大影响，使其制动距离受影响。
发明内容
本发明所要解决的技术问题是提供一种发热较小的制动机构。
本发明是通过如下技术方案来实现的：
一种制动机构，包括活动件，活动件上具有制动部，还包括制止活动件活动的制动件，制动件制止活动件活动时制动件具有向制动部方向的顶压力，且制动件与制动部之间产生滚动摩擦接触。
所述的制动件为滚轮，且制动件为至少一个，并安装在载体件上。
所述的活动件为转动件，活动件应用于车轮时活动件随车轮转动，且制动件为多个。
所述的活动件的制动部为圆环结构，制动件设于制动部靠内一侧， 制动件制动时与活动件的内壁抵触。
所述的载体件活动连接于安装座上，制动件在制动时载体件带动制动件向制动部方向顶压。
还包括驱动载体件向活动件的制动部运动的驱动件，驱动件顶压载体件，使载体件上的制动件与活动件的制动部抵接。
所述的载体件为两个且对称设置，两载体件的相同一端分别通过销轴连接在安装座上，两载体件的另一端之间预留间隙，驱动件设于该间隙中，驱动件在驱动的时候分别顶压两载体件，使两载体件反向运动。
还包括驱动载体件复位的复位件。
所述的复位件为拉簧，拉簧两端分别连接在两载体件上。
所述的驱动件与安装座活动连接，驱动件为扁形结构，驱动件驱动载体件制动时驱动件转动撑开两侧的载体件，使两载体件上的制动件与制动部抵触。
本发明的有益效果：本发明通过将传统制动机构的滑动摩擦改为滚动摩擦，由于滚动摩擦的发热较小几乎忽略不计，因此其在长时间工作状况下制动性能更加稳定，同时制动件采用多个能够保证制动效果，进一步提高产品的制动性能。
附图说明
图1为本发明的结构示意图。
具体实施方式
下面结合实施例对本发明作进一步说明。
实施例

所述的制动件2为滚轮，滚轮可根据需要设计为偏心安装，当滚轮与制动部11产生摩擦后滚轮的薄处滚动至厚处时，滚轮与制动部的挤压力越来越大，在驱动滚轮的压力不变的情况下最后滚轮迫使制动部停下，且制动件2为至少一个，并安装在载体件3上，制动件2的表面可根据需要增加刹车片，以便磨损后便于更换，也可以提高刹车性能。所述的载体件3活动连接于安装座4上，制动件2在制动时载体件3带动制动件2向制动部方向顶压。
本发明应用于汽车制动时，所述的活动件1的制动部11为圆环结构，制动件2设于制动部11靠内一侧，制动件2制动时与活动件1的内壁抵触。
还包括驱动载体件3向活动件1的制动部运动的驱动件5，驱动件5顶压载体件3，使载体件3上的制动件2与活动件1的制动部11抵接。所述的载体件3为两个且对称设置，两载体件3的相同一端分 别通过销轴连接在安装座4上，两载体件3的另一端之间预留间隙，驱动件5设于该间隙中，驱动件5在驱动的时候分别顶压两载体件3，使两载体件3反向运动。所述的驱动件5与安装座4活动连接，驱动件5为扁形结构，驱动件5驱动载体件3制动时驱动件5转动撑开两侧的载体件3，使两载体件3上的制动件2与制动部11抵触。一个驱动件5同时驱动两个载体件3，从而节约了零件的用料，而且由于是一个驱动件5，因此两个载体件3的同步性有保证，保证了制动效果。
还包括驱动载体件3复位的复位件6。所述的复位件6为拉簧，拉簧两端分别连接在两载体件3上。在两个载体件3上分别设置有供拉簧连接的拉簧孔31，两个拉簧两端分别连接在拉簧孔31上。
以上显示和描述了本发明的基本原理、主要特征和本发明的优点。本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本领域内普通的技术人员的简单更改和替换都是本发明的保护范围之内。
