Embodiment

[0021] Example: such as figure 1 , 2 , this kind of closed fat damping vibration damping clutch includes a friction plate 1, a spring plate 11, a damping plate 4, a driven plate 10 and a figure plate hub 6, wherein the friction plate 1 and the spring plate 11 are connected by a friction plate rivet 2, The driven disc 10 and the damping disc 4 form an outer closed annular cavity 13 after being riveted with spring leaf rivets 3. Apply a proper amount of sealant to the contact surface of the vibrating plate 4.

[0022] There are three sections of flat cavities 14 symmetrically distributed in the center of the annular cavity 13, and the annular cavity 13 is divided into three sections. A spring seat 12 is respectively provided at both ends of each section, and a spring seat 12 is provided between the spring seats 12. The spring 8 and the outer circle of the spring seat 12 are consistent with the cross-section of the annular cavity 13, leaving only a small gap, and the center of ...

Embodiment 2

[0027] Embodiment 2: This kind of closed grease damping damping clutch, the center of the annular cavity 13 is provided with three stoppers connected by riveting symmetrically, and there is a sector in the middle of the stoppers that can accommodate the outer edge of the spline keyboard hub 6. The gap through which the protrusion passes, and the middle of the stopper is consistent with the thickness of the outer side of the fan-shaped protrusion on the figure keypad hub 6, and only a small amount of gap is reserved. All the other structures are with embodiment 1.

Abstract

The invention relates to an enclosed grease damping vibration attenuation clutch. The enclosed grease damping vibration attenuation clutch comprises a friction piece, a spring piece, a vibration attenuation disc, a driven disc and a spline disc hub, the friction piece and the spring piece are connected through a friction piece rivet, the vibration attenuation disc, the driven disc and the spring piece are connected through a spring piece rivet, a circular ring cavity with an enclosed outer side is formed between the vibration attenuation disc and the driven disc, a plurality of retaining blocks for fixing two ends of a spring are arranged at corresponding positions of the circular ring cavity, gaps for enabling the spline disc hub to pass through are reserved in middles of the retaining blocks, and lubricating grease is filled in the circular ring cavity. The enclosed grease damping vibration attenuation clutch has the advantages that by means of an improved design principle, a novel clutch driven disc assembly which is enclosed in structure, excellent in vibration attenuation and damping characteristics, super-high in durability and convenient to adjust and control and uses the high temperature resistant lubricating grease as a damping medium is designed, and requirements of various vehicles are met.

Description

technical field [0001] The invention relates to a key part of an automobile transmission system, in particular to a closed type grease damping damping clutch. Background technique [0002] In a mechanical transmission vehicle powered by an internal combustion engine, whether it is a manual mechanical transmission (MT) or an automatic mechanical transmission (AMT), the clutch is an important part of the transmission system. The used clutches of the above-mentioned vehicles are almost all dry friction clutches. [0003] In order to improve the starting and driving comfort of the vehicle, it is usually necessary to install a torsional vibration damping system in the vehicle transmission system. The function of the clutch is to transmit (or cut off) the power of the engine so that the power of the engine can be transmitted to the gearbox (neutral gear cuts off the power). [0004] Usually the damping system is set in the clutch driven disc assembly. Its advantages are simple,...
