Background

The torsional vibration damper is an important element in an automobile clutch and mainly comprises an elastic element, a damping element and the like, wherein the spring element is used for reducing the torsional rigidity of the head end of a transmission system, so that the inherent frequency of a certain order of a transmission system is reduced, the inherent vibration mode of the system is changed, and the excitation caused by the main harmonic excitation of the torque of an engine can be avoided; the damping element is used for effectively dissipating vibration energy.

In the process of manufacturing the torsional vibration damper, after all parts are manufactured in batches, bolts are needed to be used for combining the front cover, the damping assembly and the flywheel together, and all connecting holes are aligned and then are connected through bolts.

During the operation of the specific examples, the inventors have found the following drawbacks:

at present, when the torsional damper is assembled, in order to ensure that the front cover and the periphery of the flywheel are mutually matched, a locating pin needs to be knocked into a flywheel locating hole through a copper rod at the periphery of the flywheel, a damping assembly is placed into a flywheel accommodating groove, finally, the locating hole at the periphery of the front cover is connected with the locating pin, in order to ensure that the damping assembly is centered, the upper mounting holes are aligned with holes at two sides, the positioning rod needs to be used for carrying out multiple positioning, and after positioning, external bolt connection is carried out, so that the whole process efficiency is lower.

The above-described contents fall within the technical knowledge of the inventors, and the contents of the present application do not necessarily constitute the prior art, since the technical contents in the art are huge and complicated.
