Description

一种设有延时孔的拖拉机制动泵
[技术领域]
本实用新型属于拖拉机机械技术领域，具体地说是一种设有延时孔的拖拉机制动泵。
[技术背景]
目前国内拖拉机大多数的拖拉机制动踏脚一般采用液压制动，挂车采用充气制动，拖拉机在运输作业时，为了确保挂车优先制动，需要设计一种新型的制动泵来实现。
[发明内容]
本实用新型的目的是为了克服现有技术的不足，提供了一种确保挂车优先制动的拖拉机制动泵。
为实现上述目的，本实用新型设计了一种设有延时孔的拖拉机制动泵，其特征在于：制动泵前端的顶杆处设有长槽延时孔。
本实用新型同现有技术相比，不仅安全可靠，而且能够确保挂车优先制动。
[附图说明]
图1为本实用新型结构示意图。
图2为本实用新型的工作原理图。
参见图1和图2，1为制动泵；2为顶杆；3为长槽延时孔；4为销轴；5为制动踏脚；6为钢索；7为制动气阀；8为气阀摇臂；9为气阀进口；10为气阀出口。
[具体实施方式]
下面结合附图对本实用新型作进一步说明。
如图1所示，本实用新型的制动泵1前端的顶杆2处设有长槽延时孔3。
如图2所示，长槽延时孔3与制动踏脚5上端通过销轴4连接，销轴4焊接在制动踏脚5上，当踩下制动踏脚5，钢索拉动气阀摇臂8，制动气阀7打开，把气阀进气口9进来的气体通过气阀出口10送到拖拉机后端的挂车，实现挂车制动；同时当踩下制动踏脚5时，刚开始销轴4在长槽延时孔3中滑动，走了10mm空行程，此时制动泵1未打开，进一步踩下制动踏脚5，销轴4推动制动泵1前端的顶杆2右行，此时制动泵1打开，实现拖拉机制动。
