Embodiment Construction

[0034] Exemplary embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present invention, but are not intended to exhaust all possible ways of the present invention, nor are they intended to limit the scope of the present invention.

[0035] Figure 4 shows a partial cross-sectional view of a clutch according to an embodiment of the invention, with figure 1 What is different from the clutch in the prior art shown is that a balance spring 5 is provided therein, the radially inner end of the balance spring 5 abuts against the diaphragm spring 1 , and the radially outer end abuts against the positioning pin 4 . It can be seen from the figure that the balance spring 5 is located on the inner side of the radial direction R of the positioning pin 4 as a whole. However, other positional relationships can also b...

Abstract

The invention relates to a clutch. The clutch comprises a diaphragm spring, a locating pin and a balance spring, the diaphragm spring is generally in an annular shape and provided with a plurality ofseparated fingers; the locating pin is used for fixing the diaphragm spring to a cover plate of the clutch; and the balance spring is arranged between the diaphragm spring and the locating pin in a supporting mode and / or the balance spring is arranged between the diaphragm spring and the cover plate in a supporting mode. Compared with the way not arranging the balance spring, the balance spring enables separating force of the clutch to be increased.

Description

technical field [0001] The present invention relates to clutches. Background technique [0002] It is known that the structure (partial) of a clutch is as figure 1 As shown, it has a substantially annular diaphragm spring 1 acting on the pressure plate 6 and two support rings 3 supporting the diaphragm spring 1 from both sides in the axial direction A. The diaphragm spring 1 and the support ring 3 are fixed to the cover plate 2 by means of a plurality of positioning pins 4 distributed along the circumference (only two are shown in the figure). [0003] When the clutch pedal is depressed and the clutch is disengaged, the diaphragm spring pivots on the support ring like a lever. figure 2 The characteristic curve of the variation of the separation force (vertical axis) relative to the travel of the separation finger (horizontal axis, in mm) during this process is shown, and the characteristic curve is the curve when the engine is at rest. It can be seen from the figure that...
