Description

Driven plate assembly

Technical Field

The utility model belongs to the technical field of automobile clutch, a driven plate assembly is related to.

Background

The clutch driven disc for automobile is another component of clutch, and transmits the torque of engine to speed variator through friction conversion to reduce the vibration and impact of driving system and complete the 'on' and 'off' tasks.

The outer hub and the damper disk in the conventional driven disk are generally fixedly connected through welding and riveting, when the driven disk and the outer hub are subjected to welding and riveting, the stress concentration is large, large welding residual stress and deformation exist, the possibility of generating welding defects exists, the plasticity is reduced, the welding and riveting are not uniform, the crack resistance is poor, and the like, so that the welding structure is easy to brittle failure or fatigue failure, the welding mode needs professional personnel to operate, and meanwhile, the manufacturing cost and the assembly difficulty of the driven disk are also improved.

Disclosure of Invention

The utility model aims at providing a low in manufacturing cost, connect the little and not fragile driven plate assembly of deformation to the above-mentioned problem that exists among the prior art.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a driven plate assembly, includes driven plate main part, friction disc, follows vibration damping plate, outer dish resolute, vibration damping plate and a plurality of damping spring, its characterized in that, the periphery wall of vibration damping plate on be provided with a plurality of axial interval distribution and with the integrative extension portion that sets up and form of vibration damping plate, extension portion all to extend and extend to wear out from vibration damping plate outside from the vibration damping plate, follow vibration damping plate and be located the recess of offering a plurality of axial undercut and restriction corresponding extension portion position on the upper end of extension portion department, from vibration damping plate, vibration damping plate and outer dish resolute between through a plurality of rivet fixed connection, and the center of rivet is located the central line of corresponding extension portion, the line of rivet center and driven plate main part center be greater than the line of damping spring center and driven plate main part center.

In the driven disc assembly, the number of the rivets is the same as that of the damping springs, and the damping springs are arranged between every two adjacent rivets.

In the above driven disc assembly, the number of the extending portions is twice that of the rivets, and the rivets are mounted between two adjacent extending portions.

In one of the driven disc assemblies described above, the depth of the groove is 0.9-1.2cm, and the inner diameter of the groove is equal to the outer diameter of the extension.

Compared with the prior art, the driven plate assembly is provided with a plurality of extension parts which are distributed at intervals in the axial direction on the peripheral wall of the vibration reduction plate and are integrally arranged with the vibration reduction plate, the extension parts extend outwards from the vibration reduction plate and penetrate out of the vibration reduction plate, a plurality of grooves which are recessed downwards in the axial direction and limit the positions of the corresponding extension parts are arranged on the upper end part of the vibration reduction plate at the extension parts, the arrangement of the groove and the extension part limits the position of the vibration reduction disc on the driven vibration disc, the vibration reduction disc and the outer disc are fixedly connected through a plurality of rivets, the centers of the rivets are positioned on the central line of the corresponding extension part, the connecting line of the centers of the rivets and the center of the driven disc main body is larger than the connecting line of the centers of the vibration reduction springs and the driven disc main body, the rivet structure is convenient to arrange and assemble, reduces the manufacturing cost and is small in connection deformation.
