Embodiment Construction

[0014] figure 1 The middle represents the active cylinder 1, which basically consists of a cylindrical housing 2, a piston 4 arranged axially movably in the housing, containing a piston rod 3, and a cover 5 for the housing 2 Composed, the piston defines a pressure chamber filled with hydraulic fluid.

[0015] In order to axially fix the cover 5 on the housing 2, the housing 2 is provided with two transverse bores 6 facing each other, which are each aligned with a recess 8 provided in the outer surface 7 of the cover 5, wherein, in the corresponding transverse direction Pins 9 are provided in the holes 6 and in the recesses 8 . In this case, the transverse bore 6 can be designed as a blind hole or a through hole (not shown), and the pin 9 can be designed as a cylindrical pin or a conical pin (not shown).

[0016] The pin contains an internal thread 10 at its end facing the open transverse bore 6 , which simplifies the removal of the pin 10 .

Abstract

The invention relates to an active cylinder (1). The invention is applied in the hydraulic system in automobile manufacturing, especially in the hydraulic system of the clutch system or brake operating system. In order to provide an active cylinder (1) that is simple in structure, cost-effective to manufacture and uncomplicated to assemble and disassemble, the invention proposes that the housing (2) is provided with two transverse holes (6) opposite to each other, which are respectively connected to the Recesses (8) provided in the housing surface of the cover (5) are aligned, wherein pins (9) are provided in corresponding transverse holes (6) and recesses (8).

Description

technical field [0001] The invention relates to an active cylinder substantially consisting of a housing, a piston containing a piston rod axially displaceable in the housing, and a cover for the housing, the piston defining a filling Pressure chamber for hydraulic fluid. The invention is applied in the hydraulic system in automobile manufacturing, especially in the hydraulic system of the clutch system or brake operating system. Background technique [0002] Such a solution is already known from DE 3910691 A1, wherein the cover of the housing is formed by a component guiding the piston, which is also conventionally called a welding ring, which is fastened to the housing made of plastic by means of a screw connection for axial retention . [0003] The disadvantage of this solution is that the production of the cooperating connecting elements on the housing and the cover is complex and time-critical, the assembly or disassembly of the cover to the housing of the master cyli...
