Abstract

The utility model relates to an automobile part, in particular to a long-service-life clutch cover and press plate assembly. The long-service-life clutch cover and press plate assembly is provided with a press plate, a diaphragm spring, an induction disc spring, an adjusting ring and a press cover which are sequentially stacked up, wherein two symmetrically-arranged spring installing arms are designed on the adjusting ring, and a return spring is installed on each spring installing arm and is arranged in a spring window of the press cover. The long-service-life clutch cover and press plate assembly is characterized in that 8-12 peripheral slope faces are evenly distributed on the press cover along the same circumference, the slope faces rightly facing the press cover on the adjusting ring are provided with oppositely arranged oblique blocks, reversed-tooth structures are formed on at least half of slope faces on the press cover, reversed-tooth structures are also formed on the oblique block surfaces of the slope faces which are provided with the reversed-tooth structures and face the press cover on the adjusting ring, and the reversed-tooth structures are assembled in a meshed mode. The induction disc spring and the diaphragm spring are assembled reversely. The service life of a clutch is greatly prolonged, and the long-service-life clutch cover and press plate assembly is suitable for an automobile dry friction type clutch.

Description

The long-life cover ﹠ plate assy.

Technical field

The utility model relates to auto parts and components, especially a kind of long-life cover ﹠ plate assy..

Background technique

Along with the develop rapidly of automobile industry, the client has not only pursued travelling comfort to passenger car, simultaneously to also having higher requirement the working life of passenger car easily damaged parts.Clutch is as a functor time, it also is an easily damaged parts, particularly the friction plate in the clutch driven disc assembly is more easy to wear, the residing position of clutch assembly yet (between motor and the gearbox) makes clutch assembly need pull down heavy motor and gearbox again when changing, again motor and gearbox are reinstalled in the car after changing clutch, whole replacing process is not only required great effort, the operation trouble, even if also need 3-4 hour time in the 4S shop of specialty, working hour expense is often more than hundreds of units; Be very necessary and useful the working life of therefore improving clutch.

Summary of the invention

The purpose of this utility model will solve the easy wearing and tearing of existing clutch exactly and scrap, and the problem that working life is short provides a kind of long-life cover ﹠ plate assy..

Concrete scheme of the present utility model is: improve at existing cover ﹠ plate assy., it has the platen of closed assembly successively, diaphragm spring, induction dish spring, adjust circle and gland, two spring mounting arms that symmetric arrangement is arranged in the design of adjustment circle, on each spring mounting arm return spring is housed, return spring also places the spring window of gland, it is characterized in that: the same 8-12 of being evenly distributed in described gland upper edge circumferential slope, adjusting on the circle skewback that each slope on the gland is provided with a positioned opposite, have at least the half slope to open at gland and be shaped on the pawl structure, each has also to open on the skewback surface of pawl structure slope and is shaped on the pawl structure adjusting corresponding gland on the circle, the assembling that is meshing with each other of two pawl structures; Described induction dish spring and diaphragm spring oppositely assemble.

There is the half slope to open at gland in the utility model and is shaped on the pawl structure, and the alternate interlaced arrangement with smooth slope of pawl structure slope.

Working principle of the present utility model is: in the early stage because induction dish spring and diaphragm spring are in a kind of equilibrium of forces state, this is that to be in relatively low position (be initial position with this location definition for the inclined-plane of adjusting circle and clutch gland, also be installment state), after the use clutch drived disk assy friction disc wear attenuation along with clutch, the platen of clutch can be moved to the left, the distortion of diaphragm spring will reduce, showing as the operation point at indicatrix moves forward, at this moment responding to the original equilibrium of forces relation of dish spring and diaphragm spring is broken, when clutch carries out separating action because induction dish spring can make to adjust to the reaction force of diaphragm spring a certain amount of gap appears between circle and the diaphragm spring, at this moment at return spring (under the installment state for compression) thus effect under promote to adjust circle and the relative slip of gland and increase to adjust and enclose and the inclined-plane of clutch gland is in the wear extent that relative height compensates clutch driven disc assembly and makes the position, operation point of clutch remain unchanged.So just the whole service life that improves clutch under the travelling comfort prerequisite by the thickness that increases the clutch driven plate friction plate can not influenced.

Embodiment

Referring to Fig. 1,2,3, the utlity model has the platen 1 of closed assembly successively, diaphragm spring 3, induction dish spring 6, adjust circle 4 and gland 2, two spring mounting arms 9 that symmetric arrangement is arranged in 4 designs of adjustment circle, on each spring mounting arm 9 return spring 5 is housed, return spring 5 also places the spring window 8 of gland 2, particularly: described gland 2 upper edges are same to be evenly distributed in 12 circumferential slopes 7, (referring to Fig. 4,5,6) adjusting on the circle 4 skewback 12 that each slope 7 on the gland 2 is provided with a positioned opposite, (referring to Fig. 7,8,9) there are 6 slopes 7 to open at gland 2 and are shaped on pawl structure 10, and the alternate interlaced arrangement with smooth slope of pawl structure slope, on skewback 12 surfaces of adjusting corresponding 6 pawl structure slopes on the circle 4, also open and be shaped on pawl structure 11, two

pawl structures

10 and 11 assembling that is meshing with each other; Described induction dish spring 6 oppositely assembles (namely back-to-back, both elastic force are reverse each other) with diaphragm spring 3.
