Problems solved by technology

The disadvantage of this solution is that, when ensuring a certain strength of the master cylinder, the holding fixture and the part of the housing on which said holding fixture is fastened must have a certain wall thickness
The clip connections that are necessary to be formed entail that corresponding retaining shoulders or the like must be formed on the housing, whereby the tools for producing the housing are complicated
In particular, undesired formation of burrs is caused, since the burrs are usually torn off or sheared off when mounting the holding fixture, which can cause undesirable impurities and possibly quality problems

Embodiment Construction

[0028] figure 1 A longitudinal section is shown through the master cylinder 1 , which is connected to an actuation pedal (not shown) of the motor vehicle. The master cylinder 1 comprises a cylinder housing 3 into which an axial bore 22 is introduced. Arranged in bore 22 is piston 5 , which is sealed relative to bore 22 of cylinder housing 3 via sealing rings 23 , 23 . The piston 5 rests on one side against a spring 8 , which is supported on the housing wall of the cylinder housing 3 . On the other side facing away from the spring 8 , the piston 5 has a preferably spherical recess 11 for receiving the spherical seat 7 of the piston rod 6 .

[0029] The base 7 abuts with its outer circumference against the inner circumference of the recess 11 . The piston rod 6 has a cross section which is respectively smaller than the head 9 of the piston rod 6 ( figure 2 ) or the cross-section of the base 7. With the spring 8 relaxed, the piston rod 6 protrudes approximately 2 / 3 of the ope...

Abstract

The invention relates to an arrangement and method for securing an actuating rod system of an actuating pedal in a motor vehicle. The arrangement comprises a master cylinder, on one end of which a stop ring and a securing ring are provided, in order to secure a piston rod with a foot inside a cylinder housing by means of a piston. To this end the foot and the piston rod can extend through substantially central bores of the stop ring and the securing ring. After twisting of the piston rod relative to the stop ring and a further twisting of the stop ring relative to the piston rod, the piston rod is located in a latched position relative to the stop plate, which is additionally secured by the securing ring, even in the event of possible twisting of the piston rod.

Description

technical field [0001] The invention relates to a device and a method for locking an actuating linkage of an actuating pedal in a motor vehicle. In this case, the actuating linkage includes, in particular, a master cylinder with a cylinder housing, a piston arranged thereon, and a stop ring for locking the piston rod within the cylinder housing. Background technique [0002] The master cylinder is used to transmit force hydraulically. This is based on the transmission of force from the master cylinder to the slave cylinder via a hydraulic medium, eg mineral oil. In an actuating device for actuating the clutch of a motor vehicle driven by an internal combustion engine, the master cylinder is usually connected to the clutch pedal, so that actuation of the clutch pedal causes a piston to move in the master cylinder, which movement is transmitted via the hydraulic medium to the slave cylinder and causes the clutch to be actuated, This means that the engagement or disengagement...
