Description

带有制动调节系统的制动装置
本发明涉及一种车轮总成，它设置有一个托架；一个车轮，所述车轮安装在托架上，并可绕一个轴转动；一个制动件，所述制动件可相对于车轮移动，并包括一个设有螺纹的制动销，环绕着制动销具有一个开有互补螺纹的可移动的制动盘；一个锁止盘，以沿着螺纹的方向固定制动盘的位置。当制动销沿着自身轴线方向向着车轮移动时，为了制动车轮，制动盘可以与车轮相接合。
这种车轮总成是公知的，它可根据要求进行装配。例如，它可以用在飞机上配发食品的小车上。
由于车轮或者是制动盘本身的接合表面的磨损，随着使用时间的延长，其制动性能也变差。为了克服上述问题，制动盘在制动销上的位置是可变的。为了沿着制动销移动制动盘，锁止盘需要被拆开，同时，制动盘必须沿正确方向移动，最后，再次将制动盘安装上。根据现有技术，锁止盘被夹紧在制动盘和一锁止螺母之间。由于设置在车轮和托架之间的锁止螺母很难被触及，因此，锁止盘很难被移动和安装。而且，需要用到额外的工具。
本发明的目的是要使得移动和安装锁止盘变得更加容易，并且，也使得不须用到额外的工具即可进行这些工作。
为达到上述目的，根据本发明，所述的锁止盘至少设有一个止动爪，所述的止动爪相对于制动销径向布置，并可沿制动销的轴向移动。为了阻止制动盘的旋转，在制动盘上开有至少一个用以容纳所述止动爪的径向槽。
既然制动盘的旋转仅仅通过轴向突出的止动爪被阻止，那么，通过将止动爪从径向槽中提升，就可使制动盘松开。这些工作不须用到工具就可做到，因此，可以大大地简化制动盘的调整工作。
在一个优选实施例中，止动爪通过一个压缩弹簧而被压入到槽中。压缩弹簧最好环绕着制动销布置。而且，止动爪上最好设有孔眼，所述孔眼环绕着制动销布置。为了阻止止动爪的旋转，制动销和孔眼在一侧被整平。
在不需用到任何工具而继续对制动盘进行简单调整的同时，本设计采用少量构件即可阻止止动爪从槽中无意地掉出来，从而造成制动盘的转动，所述的构件是很坚固耐用的，并且基本不需要保养。
在上述的优选实施例中，也可以在制动爪的端部设置有一个凸缘，它可以简化轴向移动止动爪的手工劳动。
下面，将结合附图对本发明进行更详细地描述：
图1是带有制动装置的车轮总成的横截面图；
图2是沿图1所示制动装置的II-II线剖开的横截面图。
图1所示的车轮总成包括有：一个托架1，所述托架通过枢轴件2可动地与附件板3连接；一个车轮5，它环绕着轴4安装，并安装在托架1上；一个制动件7，它安置在衬套6中，并可相对于车轮5移动。制动件7包括一个制动销8，在制动销8上安装有制动盘9。随着制动销向着车轮5移动，使得制动盘9可以和车轮5接合。所示的实施例中包括有一个压缩弹簧14，当制动盘9未起作用时，所述的压缩弹簧14会在一个间隙位置保持住制动盘9。
车轮总成例如通过附件板3附着在一个小车的底部，小车可被设计成带有制动机构，通过一个传动系统，所述的制动机构可将制动销压到车轮上。当松开制动系统时，通过弹簧14，制动盘从车轮上移开，这样，车轮就可以再次转动。
制动销8上设有螺纹，在其上装有制动盘9，在所述的制动盘9上开有互补螺纹。由于制动盘9的转动，使得它可以在平行于制动销8的轴线方向上移动。重要的一点是，当车轮5和/或制动盘本身的表面磨损之后，将不会产生足够的摩擦力。
为了保证制动盘9不会以不期望的方式转动，从而使其高度发生变化，制动盘9上开有槽10。围绕着制动销8而固紧的锁止盘11上的止动爪12能够锁定在这些槽中的一个中，因此，制动盘9的转动被阻止。为了保证锁止盘11本身不会随制动盘9一起转动，锁止盘11中的孔眼和制动销8被设计成具有一个平整截面，并且，这些平整截面相互配合。
为了使得止动爪12处于槽10中，通过一个压缩弹簧16将止动爪12压入槽10中。为了使得制动头部9可以相对于制动销8和止动爪12转动，借助凸缘13，并克服弹簧16的压力，止动爪12可从槽10中提升出来。
图2是沿图1所示制动装置的II-II线剖开的横截面图。其中，可以很清楚地看到制动销8和锁止盘11的平整部分。既然止动爪12已经被压入槽10中的一个中，那么制动盘9将不可能再相对于制动销8转动了。
