Description

叉车驱动桥自动驻车装置
技术领域:
本实用新型涉及叉车技术领域,更具体地说涉及叉车驱动桥驻车制动装置。 
背景技术:
现有的叉车驱动桥驻车制动装置是在叉车停车后,通过拉手刹来制动,拉动手刹使制动蹄张开来实现叉车驱动桥传动轴的制动。其不足之处是:叉车停车后,它需要手动来制动,无法实现停车后自动驻车制动。 
实用新型内容:
本实用新型的目的就是针对现有技术之不足,而提供一种叉车驱动桥自动驻车制动装置,它可以实现叉车停车后叉车驱动桥自动驻车制动。 
本实用新型的技术解决措施如下: 
叉车驱动桥自动驻车装置,制动齿轮与叉车驱动桥传动轴通过花键连接在一起,摩擦片通过花键连接在制动齿轮上,二个相邻的隔片之间置有一个摩擦片,叉车轮毂壳与叉车驱动桥壳体固定连接在一起,叉车驱动桥壳体上成型有制动液压油道,弹簧座固定在叉车轮毂壳上,回位弹簧一端压制在活塞上、另一端压制在弹簧座上。 
本实用新型的有益效果在于:它可以实现叉车停车后叉车驱动桥自动驻车制动。 
附图说明:
图1为本实用新型的结构示意图 
图中:1、叉车驱动桥传动轴;2、制动齿轮;3、摩擦片;4、隔片;5、活塞;6、叉车轮毂壳;7、叉车驱动桥壳体;71、液压油道;8、弹簧座;9、回位弹簧。 
具体实施方式:
实施例:见图1所示,叉车驱动桥自动驻车装置,制动齿轮2与叉车驱动桥传动轴1通过花键连接在一起,摩擦片3通过花键连接在制动齿轮2上,二个相邻的隔片4之间置有一个摩擦片3,叉车轮毂壳6与叉车驱动桥壳体7固定连接在一起,叉车驱动桥壳体7上成型有制动液压油道71,弹簧座8固定在叉车轮毂壳6上,回位弹簧9一端压制在活塞5上、另一端压制在弹簧座8上。 
工作原理:叉车工作时,制动液压油通过液压油通道71进入叉车驱动桥壳体7与活塞5形成的腔室内,活塞5产生推力将回位弹簧9压缩,此时隔片4与摩擦片3处于分离状态不接触,叉车驱动桥传动轴1工作转动。当叉车停车后,叉车的液压油系统因无动力提供不再有油压通过液力油道71向活塞5加力,活塞5在回位弹簧9的作用力下回位,安装在活塞5上的隔片4与摩擦片3接触压紧产生摩擦力,从而实现叉车驱动桥传动轴1的制动。 
现有技术中,通过手拉驱动制动蹄,制动蹄张开后给压盘压力来实现制动。本实用新型通过压簧9来实现叉车停车后自动制动,它可以实现叉车停车后叉车驱动桥自动驻车制动。
