Abstract
The utility model discloses a clutch cover assembly, and provides a self-compensating abrasion-resistant double-disc-spring clutch cover assembly, which is long in service life and comprises covers (1), pressure plates (2) and diaphragm springs (3). The double-disc-spring clutch cover assembly is characterized in that a bending claw (11) and a supporting rib (12) are arranged on each cover (1), each supporting rib (12) is concave towards a bending direction of the corresponding bending claw (11), a disc spring retainer ring (4) is disposed inside each bending claw (11), lower outer edges of the disc spring retainer rings (4) are opposite to the supporting ribs (12), and each diaphragm spring (3) is clamped between the corresponding supporting rib (12) and the corresponding disc spring retainer ring (4). The double-disc-spring clutch cover assembly can be widely applied to the field of automobile clutches.
Description
Technical field
The utility model relates to a kind of pair of dish spring clutch cap assembly.
Background technique
Clutch is as very important in a car transmissions assembly, and when automobile running, its frequency of utilization is high.In vehicle traveling process, the active part on the clutch constantly engages with secondary part and separates.And clutch cover is to separate inner with the outside assembly of clutch, and it still is the critical elements of support membrane flat spring, and clutch cover and diaphragm spring and platen etc. have constituted clutch cover and plate assembly jointly.Diaphragm spring on the clutch cover and plate assembly in the past is by covering punching, adopting rivet that diaphragm spring is riveted on then and cover, and rivet had both played a part supporting here, also played a part fixedly diaphragm spring.But, need rivet could be installed covering punching, make processed complex, cost rises, and install, dismounting is inconvenient, structure is also brief inadequately.In addition, in the existing clutch, the general support ring that adopts of the lower support point of diaphragm spring.And the lever ratio of support ring is lower, and the Separating force that diaphragm spring separates finger tip is bigger, and its separation rate is lower.In addition, under motoring condition, through regular meeting the gap appears between diaphragm spring and the platen; and diaphragm spring and platen contact or separation process in; the situation that the contacted place of platen and diaphragm spring usually can occur wearing and tearing like this, has greatly reduced the working life of clutch.
The model utility content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and the clutch cover and plate assembly of a kind of self compensation, wear-resistant, long service life is provided.
The technological scheme that the utility model adopted is: the utility model comprises lid, platen, diaphragm spring, described cover be provided with curved pawl, to the recessed bearing rib of the bending direction of described curved pawl, in described curved pawl, be provided with dish spring back-up ring, the following outer rim of described dish spring back-up ring is relative with described bearing rib, and described diaphragm spring is clamped between described bearing rib and the described dish spring back-up ring.
Described lid and described curved pawl have a style of one's own.
The beneficial effects of the utility model are: because the utility model is provided with curved pawl described covering, also be provided with to the recessed bearing rib of the bending direction of described curved pawl, adopt the curved pawl structure that carries bearing rib, so, the utility model makes that the structure of clutch is more brief, and optimizes more; Owing in described curved pawl, be provided with dish spring back-up ring, the following outer rim of described dish spring back-up ring is relative with described bearing rib, described diaphragm spring is clamped between described bearing rib and the described dish spring back-up ring, so, the lower support point of diaphragm spring adopts dish spring back-up ring, strengthen the lever ratio of clutch, thereby reduced the Separating force of diaphragm spring separation finger tip, improved separation effect; Under the state of automobilism, by described dish spring back-up ring, compensated the gap between diaphragm spring and the described bearing rib, also compensated simultaneously the gap between described diaphragm spring and the described platen, good self compensation, anti abrasive effect have been played, the working life of greatly having improved clutch.
So the utility model is the clutch cover and plate assembly of a kind of self compensation, wear-resistant, long service life.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present utility model;
Fig. 2 is the A-A sectional view among Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, the utility model comprise cover 1, platen 2, diaphragm spring 3, described lid 1 is provided with curved pawl 11, to the recessed bearing rib 12 of the bending direction of described curved pawl 11, in described curved pawl 11, be provided with dish spring back-up ring 4, the following outer rim of described dish spring back-up ring 4 is relative with described bearing rib 12, and described diaphragm spring 3 is clamped between described bearing rib 12 and the described dish spring back-up ring 4.Described lid 1 has a style of one's own with described curved pawl 11.
On described lid 1, bearing rib 12 is set directly, and with the curved pawl 11 that described lid 1 has a style of one's own, make that greatly the structure of clutch is simpler, also optimize more.In described curved pawl 11, dish spring back-up ring 4 is set, compares, strengthened the lever ratio of clutch, thereby reduced the Separating force that described diaphragm spring 3 separates finger tip, improved separation effect with common support ring structure.Described diaphragm spring 3 is under the clamping of described bearing rib 12 and described dish spring back-up ring 4, compensated gap between described diaphragm spring 3 and the described bearing rib 12 by described dish spring back-up ring 4, self compensation, anti abrasive effect have been played, the working life of having improved clutch.
In sum, the utility model can be widely used in the automobile clutch field.
Claims (2)
1. two dish spring clutch cap assembly, comprise lid (1), platen (2), diaphragm spring (3), it is characterized in that: described lid (1) is provided with curved pawl (11), to the recessed bearing rib (12) of the bending direction of described curved pawl (11), in described curved pawl (11), be provided with dish spring back-up ring (4), the following outer rim of described dish spring back-up ring (4) is relative with described bearing rib (12), and described diaphragm spring (3) is clamped between described bearing rib (12) and the described dish spring back-up ring (4).
2. according to claim 1 pair of dish spring clutch cap assembly is characterized in that: described lid (1) has a style of one's own with described curved pawl (11).
