Description

Cover assembly shock absorber integral type clutch

Technical Field

The utility model relates to a field of engineering machine tool key spare part, concretely relates to lid assembly shock absorber integral type clutch.

Background

Since china construction machinery is started late and mostly evolved with automobile clutches. Since the late 20 th century, various vehicle models have been introduced from relatively developed countries such as germany, italy, japan, and the united states. Meanwhile, the technology of relevant key parts, such as an engine, a gearbox and the like, and the technology of a clutch are introduced. Along with the fast reading development of Chinese engineering machinery complete machine manufacturers, matching part enterprises have great demands, and as many matching part enterprises in China do not master core technologies and have insufficient independent innovation, the whole vehicle operation load is continuously increased through long-time development, the bearing capacity of corresponding components is not improved, and the market potential hazards are greatly reduced.

Taking the company as an example, the product structure for the domestic engineering machinery excavator is old, most of the products continue to use the traditional automobile clutch, and the engineering machinery has severe working environment and frequent operation, which puts higher requirements on the clutch.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough of prior art existence, and provide a lid assembly shock absorber integral type clutch, be suitable for the wheel of different horsepower sections and dig the machine, performance promotes greatly, can progressively replace old structure, reduces the too much variety of clutch, reaches the effect that increases batch, reduce cost.

The purpose of the utility model is accomplished through following technical scheme: the integrated clutch of the cover assembly shock absorber comprises a pressure plate and a clutch cover covering the pressure plate, wherein a cavity is formed in the pressure plate and the clutch cover, the shock absorber assembly is arranged in the cavity and is fixed with the clutch cover through a bearing pin B, a diaphragm spring is fixedly arranged on one side, close to the clutch cover, of the shock absorber assembly, the diaphragm spring is fixedly contacted with the bearing pin B through a bearing ring, the horizontal part of an elastic hook is fixedly arranged at the end part of the pressure plate through a bearing pin A, and the hook part of the elastic hook is clamped between the diaphragm spring and the clutch cover.

As a further technical scheme, a transmission piece is arranged at the contact position of the pressure plate and the elastic hook.

Preferably, the contact part of the shock absorber assembly and the diaphragm spring is subjected to high-frequency quenching treatment.

The utility model has the advantages that: through the improved design, a clutch product which can adapt to higher power and has the buffering and vibration damping effects is manufactured, and the standardization and the generalization of main parts are realized; the integrated design is adopted, the function of transmitting torque of the traditional clutch is integrated, the buffering and vibration damping effects are achieved, and a host factory does not need to purchase the clutch and the vibration damper separately, so that the large market space is achieved.

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a cross-sectional view taken at P-P of fig. 1.

Description of reference numerals: the clutch comprises a pressure plate 1, a transmission plate 2, a supporting pin A3, an elastic hook 4, a diaphragm spring 5, a supporting ring 6, a supporting pin B7, a damper assembly 8 and a clutch cover 9.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

example (b): as shown in fig. 1 and 2, the cover assembly shock absorber integrated clutch includes a pressure plate 1 and a clutch cover 9 covering the pressure plate 1, a cavity is formed inside the pressure plate 1 and the clutch cover 9, a shock absorber assembly 8 is disposed in the cavity and fixed with the clutch cover 9 through a support pin B7, a diaphragm spring 5 is fixedly mounted on one side of the shock absorber assembly 8 close to the clutch cover 9, the diaphragm spring 5 and the support pin B7 are fixed by contact of a support ring 6, a horizontal part of an elastic hook 4 is fixedly mounted at the end of the pressure plate 1 through a support pin A3, and a hook part of the elastic hook 4 is clamped between the diaphragm spring 5 and the clutch cover 9; and a transmission piece 2 is arranged at the contact position of the pressure plate 1 and the elastic hook 4.

As a preferable technical scheme, the contact part of the shock absorber assembly 8 and the diaphragm spring 5 is subjected to high-frequency quenching treatment, so that good wear resistance is achieved.

The engineering machinery applied to the clutch product related to the embodiment is an 8-13 ton wheel excavator, and the power is 55KW-62.5 KW. The specific design idea of this embodiment is: the clutch assembly with the conventional 255 specifications has the functions of bearing the operation of a whole vehicle with a larger horsepower section, improving the separation efficiency, improving the wear resistance and improving the structural stability, wherein the most important is that a set of vibration reduction system is designed in the clutch assembly on the premise of ensuring that the working principle of the clutch is unchanged, the working point is unchanged and the like. The pressing force of the clutch product related to the embodiment is 6800-7200N, the torque of the damper is 600N.m, the pressing force is 20% larger than that of a conventional 255-specification clutch, and the pressing force can be adjusted according to horse power sections with different models, different spline parameters and the like so as to meet different conditions.

The elastic hook 4 is a standard part and provides protection for the pressure plate 3 while heightening the whole longitudinal space of the clutch. The structure can play a very important protection role in batch production and transportation, and meanwhile, the design also plays a key role in clutch separation. Without an integral design, the engine is usually followed by a set of flywheels for the damper, i.e. a set of flywheels is installed after the damper to install the clutch assembly. The internal space of the whole vehicle is greatly wasted, the transmission efficiency is reduced, and the key cost is high; compared with the prior art, the shock absorber with the cover assembly has the remarkable advantage of integrated design.

It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
