Description

Low-noise shock absorber assembly

Technical Field

The utility model relates to a shock absorber assembly especially relates to a low noise shock absorber assembly.

Background

With the improvement of living standard, the requirements of people on the comfort, the power performance and the fuel economy of an engine of an automobile are continuously improved, and the noise of a whole automobile transmission system also becomes an important index for evaluating the whole performance of the automobile.

Driven plate assembly is as the transmission mechanism of power, can effectual transmission engine power, but, traditional driven plate assembly damping effect is poor, and the comfort level is low, has been difficult to satisfy people to the comfort level demand of low noise.

Disclosure of Invention

The utility model provides a to above technical problem, provide a simple structure, safe and reliable, can effectively reduce the low noise shock absorber assembly of drive train noise.

For this reason, the technical scheme of the utility model, a low noise shock absorber assembly is equipped with the fixed plate, be equipped with the window on the fixed plate, be equipped with damping spring in the window, fixed plate one side is equipped with the clutch dish, the opposite side of fixed plate is equipped with the damping dish, the central point of fixed plate puts and is equipped with the die cavity, be equipped with wheel hub in the die cavity, clutch dish and damping dish all are equipped with the spring hole in the position that corresponds with the fixed plate window, be equipped with the rivet hole on the clutch dish, also be equipped with the rivet hole on wheel hub and the damping dish on corresponding the position with.

Preferably, the damping spring in the window is a large spring and a small spring is sleeved in the large spring.

Preferably, the number of the windows on the fixing plate is 8, and the windows are uniformly distributed in the circumferential direction.

Preferably, a flywheel is fixedly arranged below the shock absorber assembly, a groove is formed in the flywheel, the shock absorber assembly is placed in the groove of the flywheel, and a driven plate assembly and a pressure plate assembly are sequentially arranged above the shock absorber assembly from bottom to top.

The utility model has the advantages that:

(1) the damping spring is arranged in the window of the fixing plate, and the damping spring is sleeved with the large spring and the small spring, so that the rigidity of the spring is improved, the service life of the spring is prolonged, and a better damping effect can be achieved;

(2) the shock absorber assembly is directly fixed on a flywheel of the engine, axial load impact is reduced, alternating stress borne by a transmission system is reduced, the vehicle cannot shake during clutch, noise of the transmission system is eliminated to the maximum extent, the combination smoothness and the operation comfort are improved, and the service life of the clutch assembly is prolonged.

Drawings

Fig. 1 is a schematic view of an assembly structure of an embodiment of the present invention;

fig. 2 is a cross-sectional view of an embodiment of the invention.

The symbols in the drawings illustrate that:

1. a fixing plate; 2. a clutch disc; 3. a vibration damping disk; 4. a small spring; 5. a large spring; 6. riveting; 7. a hub; 8. and (4) a window.

Detailed Description

The present invention will be further described with reference to the following examples.

As shown in fig. 1-2, a low-noise damper assembly is provided with a fixing plate 1, a window 8 is arranged on the fixing plate 1, a damper spring is arranged in the window 8, the damper spring is a big spring 5, and a small spring 4 is sleeved in the damper spring, and the way that the big spring 5 is sleeved with the small spring 4 improves the rigidity of the damper spring, prolongs the service life of the damper spring, and can achieve a better damper effect.

1 one side of fixed plate is equipped with clutch disk 2, the opposite side of fixed plate 1 is equipped with damping disc 3, the central point of fixed plate 1 puts and is equipped with the die cavity, be equipped with wheel hub 7 in the die cavity, clutch disk 2 and damping disc 3 all are equipped with the spring hole in the position that corresponds with the fixed plate window, be equipped with the rivet hole on clutch disk 2, also be equipped with the rivet hole on wheel hub 7 and damping disc 3 on the rivet hole that corresponds the position with clutch disk 2, the rivet hole is the circumferencial direction equipartition and arranges, the quantity in concrete rivet hole is confirmed according to transmission torque size.

The number of the windows on the fixing plate 1 is 8, and the windows are uniformly distributed in the circumferential direction, and other number of windows can be arranged, which mainly depends on the requirements of torque and rigidity.

The assembling process of the scheme is that the small spring 4 is firstly transmitted into the large spring 5 to form the damping spring, the damping spring is fixed in the window of the fixing plate 1, the rivet penetrates into the rivet hole of the clutch disc 2, the spring groove of the clutch disc 2 corresponding to the fixing plate 1 and the damping spring is placed on the plane of the clutch disc 2, the big end of the hub 7 upwards places the rivet hole corresponding to the rivet position in the cavity of the fixing plate 1, the rivet corresponding to the rivet hole of the damping disc 3 is placed on the fixing plate 1 and the hub 7, and finally all parts are riveted together to form the shock absorber assembly.

The flywheel is fixedly arranged below the shock absorber assembly, a groove is formed in the flywheel, the shock absorber assembly is fixed in the groove of the flywheel, and the driven plate assembly and the pressure plate assembly are sequentially arranged above the shock absorber assembly from bottom to top. The shock absorber assembly is directly fixed on a flywheel of the engine, axial load impact is reduced, alternating stress borne by a transmission system is reduced, the vehicle cannot shake during clutch, noise of the transmission system is eliminated to the maximum extent, the combined smoothness and the operation comfort level are improved, the service life of the clutch assembly is prolonged, and the use requirements of the vehicle in various environments can be met.
