Abstract

本发明涉及一种主动缸(1)。本发明应用于汽车制造中的液压系统内，尤其是离合器系统或制动操作系统的液压系统内。为了能提供结构简单、能成本有利地制造和不复杂地装配及拆卸的主动缸(1)，本发明提出，壳体(2)设有两个彼此相对的横向孔(6)，它们分别与设置在盖(5)的外壳面中的凹陷(8)对齐，其中，在相应的横向孔(6)和凹陷(8)中设置销(9)。

Description

主动缸
技术领域
本发明涉及一种主动缸，其基本上由一壳体、一在该壳体中可轴向移动地设置的包含一活塞杆的活塞和用于该壳体的盖组成，该活塞限定一填充了液压液体的压力室。本发明应用于汽车制造中的液压系统内，尤其是离合器系统或制动操作系统的液压系统内。
背景技术
这种方案已由DE3910691A1公开，其中，壳体的盖由引导活塞的、习惯上也称作焊接环的构件构成，该构件为了轴向保持而借助螺纹连接被固定在由塑料组成的壳体上。
该方案的缺点在于，在壳体和盖上配合作用的连接元件的制造费事且时间紧迫，盖与主动缸的壳体的装配或拆卸繁琐地设计以及尤其是当在主动缸上进行功能分析或保证分析时，必须在主动缸周围提供相应的用于必须的旋接过程的自由空间。
发明内容
本发明的任务是提出主动缸的另一种构型，其制造简单，其壳体和盖能成本有利地制造和不复杂地装配及拆卸。
按本发明，该任务在合乎类型的主动缸中这样解决，即，壳体构造有两个彼此相对的、分别与设置在盖的外壳面中的凹陷对齐的横向孔，其中，在相应的横向孔和凹陷中设置销。
本发明的优点在于，提供一种主动缸，其中，用于制造壳体与盖之间的作用连接的连接元件能不复杂且成本有利地制造。此外，能实现盖在主动缸的壳体上快且很小花销的装配和拆卸，其中尤其是拆卸即使在有限的位置关系下也能得到保证。
本发明有利的进一步构型如下，主动缸基本上由壳体、在该壳体中轴向可移动地设置的、包含活塞杆的活塞和用于该壳体的盖组成，该活塞限定一填充了液压液体的压力室，该壳体设有两个彼此相对的横向孔，它们分别与设置在所述盖的外壳面中的凹陷对齐，其中，在相应的横向孔和凹陷中设置销，该销在其向着敞开的横向孔的端部上包含一内螺纹,所述横向孔构造成盲孔，所述壳体在对应所述横向孔的两端部的位置上分别具有敞开部和封闭部，所述销的内螺纹朝向所述敞开部，而背离所述封闭部，在拆卸所述壳体与所述盖时，工具能够通过所述敞开部旋入所述内螺纹中，在所述盖装配在所述壳体上时，所述盖至少部分位于所述壳体中，所述盖位于所述壳体中的部分包设在所述活塞的外周面上，在一径向方向上所述销的位置对准所述活塞。
其中，销构造成圆柱形销或锥形销——保证商业上通用的标准间能得到应用。
其中，横向孔构造成盲孔或通孔——保证了销的简单接收和销的不复杂的装配和拆卸可能性。
其中，销包含内螺纹——能实现销的及由此盖与壳体的进一步简化的拆卸。
接下来根据一实施例和所属的附图详细阐述本发明。
附图说明
图1主动缸的纵截面，
图2主动缸的沿图1中线A-A的截面图。
具体实施方式
图1中表示主动缸1，其基本上由一圆柱形的壳体2、一在该壳体中轴向可移动地设置的、包含一活塞杆3的活塞4和用于该壳体2的盖5组成，该活塞限定一填充了液压液体的压力室。
为了将盖5轴向固定在壳体2上，壳体2设有两个彼此相对的横向孔6，它们分别与设置在盖5的外壳面7中的凹陷8对齐，其中，在相应的横向孔6和凹陷8中设置销9。在此，横向孔6可构造成盲孔或未示出的通孔，销9可构造成圆柱形销或未示出的锥形销。
所述销在其向着敞开的横向孔6的端部上包含一内螺纹10，由此简化了销10的拆卸。
