Description

低残留空气总泵活塞总成
技术领域
本实用新型属于离合、制动总泵用低残留空气总泵活塞结构,具体地说是一种减少离合、制动油路系统内部气体残留空间的新结构。
背景技术
如图1所示,现有车辆上的离合、制动总泵在装车后总成内部有残留气体1,造成离合、制动系统有空气排不尽现象,影响离合系统的使用效能。
发明内容
本实用新型的目的是设计出一种低残留空气总泵用活塞总成,降低离合、制动总泵内部残留气体,从而提高离合、制动系统效能。
本实用新型的技术方案是:低残留空气总泵活塞总成,在活塞前端加一导向套。
上述低残留空气总泵活塞总成,所述导向套前端加一环形凸台,其外圆面均匀分布六道通油槽。
本实用新型的优点是:1)相比原有的结构,本实用新型增加导向套,减少了活塞与缸壁磨损,从而提高总成的使用寿命。2)本实用新型形状与原有的活塞结构相比,离合总泵内部气体残留空间大大降低。3)本实用新型设计巧妙、结构更加合理。
附图说明
图1为现有活塞总成结构示意图;
图2为本实用新型活塞总成结构示意图;
图3为导向套等轴测图;
图4为导向套通油槽示意图;
具体实施方式
下面结合附图及实施例对本实用新型作进一步说明。
如图2所示,本实用新型在活塞3前端加一导向套2,用于减少活塞3与缸壁间磨损,提高总成使用寿命。导向套2装入活塞总成前端,局部填充了气体残留空间。如图3和图4所示,导向套2外圆均匀分布六道通油槽4,保证油路的通畅。
