Abstract

The invention relates to a Ausrueckring for transmitting the Ausrueckbewegung of a Ausruecklager serving as Betetigungselemente tongues of the plate spring of a motor vehicle clutch. The Ausrueckring consists of a mounting bush with Ausrueckplatte, a tension spring and a plated thrust washer, wherein the Ausrueckplatte is engaged with the plate spring. The tongue ends of the plate windows are arranged between the tensioning spring and the bending radius of the Ausrueckplatte. On the Ausrueckplatte lugs are provided which protrude into the spaces between the tongues. Relative axial movements of the individual parts are prevented by special bending tabs. Fig.1 and 2

Ausrüekring

The invention relates to a release ring zur.Übertragung the disengagement of a release bearing on the e as an actuating element. Dieaeaden tongues of! Belleville spring of a motor vehicle clutch ·

Characteristic of the known technical solutions

Hach DE 24 19 7oo is a release ring Torgestlagen, which is supported on the outside of the! Belleville spring by means of a wire ring and held on the inside of! Belleville spring by a trained as a plate spring retaining spring in its position is "This arrangement is the usual wear reduced to the tongue ends of the spring Seiler <> However, the arrangement as such is YerschieiSanfällig "especially in the area of kreisringföraigen start part. in addition, a relatively high 3? _e rtigungsaufwand required

To further reduce the? E ^r actuating effort and reduce wear to 29 24 284. release ring in the form of a u-shaped sheet metal sleeve with different legs serve to Dl "The longer leg is provided as a thrust washer for the release bearing, while the shorter leg of the cohesion Device served For this purpose, it is divided on its circumference into individual segments, which coincide with corresponding recesses in the retaining spring. When mounting the plate spring is pushed onto the release ring and secured by the retaining spring. The retaining spring is thereby pushed onto the release ring using its recesses and the segments of the shorter leg

and secured by a corresponding rotation «. To fix the position of the release ring and to center it with the plate spring, the retaining spring is provided with spring lugs which "lock into the spaces between the spring tongues of the diaphragm spring during rotation." Another solution is to provide the inner side of the long leg with retaining lugs with the plate spring into engagement au bring *

This device is easy and quick to assemble, but requires at a relatively high Fartigungsaufwand a corresponding manufacturing accuracy j, for example, with respect to the complicated Fora de3 inner circumference of the retaining spring · Inaccuracies and wear lead to unwanted noise and under circumstances for releasing the retaining spring and thus failure the device _o

Object of the invention

The aim of the invention is to provide a simple and easy-to-manufacture Ausrückring in his art, which is subject to only a small "wear and puncture even suffers from prolonged operation"

Explanation of the essence of the invention

The object of the invention is to arrange the individual ropes of the release ring to each other so that the wear is reduced to a minimum, the known disadvantages such as noise and premature release are avoided "without the puncture of the release ring is impaired."

Bretherungsgemäß the object is achieved in that the individual parts of the device are pushed onto serving as a mounting bushing unilaterally angled pipe section of sheet metal and guided centrally to each other. After assembly, the other edge of the mounting sleeve is flange-like umggebördelt so that sliding apart of the parts is prevented. In detail, the release ring consists of the tension spring, the release plate, the mounting sleeve and a thrust washer. The tension spring, a telescopic

The spring plate is then pushed onto the fastener book and, as the stopper is used, the plate spring on the Yerspann spring is in contact with the plate. The release plate is plate-shaped and has rabbits on the inner circumference »Which engage in the intermediate spaces between the tongues of the plate spring when assembling, so that the plate spring is supported on the one hand at the bending radius of the release plate and on the other hand, fixed in position» To Yarhinäerung of relative axial movement of the release plate dia mounting bush is provided with bending tabs * which at Usibördeln of the edge are pressed so far inward ₉ that they axa jpn ^ r ^ p radius of the release plate come to the plant * Thus all the file are firmly clamped together «

By this design, the friction between the einseinen part is reduced to ice Minissusi and ensures a backlash Tarbindung the Aasrückringes with the Seiler spring ^ this arrangement only axial movements of the release ring-permitting unwanted noise does not occur _o

To prevent wear of the release plate, it is provided with a special thrust washer. «The thrust washer is clad with a sliding material and is connected to the release plate by welding. · The contact surface for the release bearing forms until the thrust washer ·
