Problems solved by technology

[0004] However, the prior art always has the disadvantage that the bonding of the magnet into the piston during assembly involves high process costs and / or risks
Furthermore, in the double magnet design, there is the problem, depending on the arrangement of the magnets, that the two magnets would attract each other and thus be (for sticking) worse positioned

Embodiment Construction

[0036] figure 1 Shown is a double magnet holder 1 into which two magnets 2 (not visible) are mounted, which is fitted into a piston 3 . The piston 3 is located in a slave cylinder 4 which furthermore has a sensor 5 . The double magnet holder 1 has a base body 6 , wherein webs 7 space two receiving regions 8 , each for a magnet 2 , at a distance from one another. The magnets 2 are respectively located between the two pretension tongues 9 . The slave cylinder 4 further has a release bearing 10 . Depending on the position of the piston 3 , that is to say depending on the position of the magnet 2 of the double magnet holder 1 , a signal is detected by the sensor 5 .

[0037] figure 2A perspective view of the double magnet holder 1 with two magnets 2 according to the first embodiment of the invention is shown in the assembled state. The magnets 2 are each located in a receiving area 8 of the base body 6 of the double magnet holder 1 . A web 7 is arranged between the receivin...

Abstract

A dual magnet holder (1) for receiving two magnets (2). The magnet is used for the piston (3) of the hydraulic slave cylinder (4). The magnet (2) is arranged and designed to interact with the sensor (5) to derive an inference about the position of the piston (3) of the slave cylinder (4). The base body (6) has two receiving areas (8) for each magnet (2). The receiving area (8) has such size that in a state that the magnets (2) are mounted in the receiving area (8) and the dual magnet holder (1) is mounted in the piston (3), the magnets are maintained on a position required by operation on thebase body (6) without clearance. The invention also relates to a hydraulic driven cylinder (4) having a housing for mounting in a clutch or brake system. The piston (3) is supported in the housing inan axially movable manner. According to the invention, the dual magnet holder (1) holding the two magnets (2) is mounted in the piston (3).

Description

technical field [0001] The invention relates to a double magnet holder for receiving two magnets for a piston of a hydraulic slave cylinder, such as a piston for a clutch slave cylinder, especially for a CSC / Concentric Slave Cylinder (Concentric Slave Cylinder) wherein the magnet is arranged and designed to draw conclusions about the piston position of the slave cylinder in cooperation with the sensor, wherein the (substantially rectangular) base has two adjacent, preferably oppositely spaced Spaced apart and / or separated by at least one web, in particular one-piece receiving regions, each for a magnet. Background technique [0002] Pistons are known from the prior art in which magnets are plugged in and fixed adhesively or by clips (for example by means of disc springs). [0003] For example, document DE 10 2015 223 972 A1 also discloses an actuator for actuating a friction clutch, which has a housing and a piston movable in the axial direction in the housing, wherein on t...
