Abstract
The utility model discloses a torsional vibration damper, which comprises an inertia ring, a hub and a rubber ring, wherein vibration damper gear profiles are arranged on the outer surfaces of the inertia ring and the hub respectively; and the rubber ring is arranged between the inertia ring and the hub. By adjusting the structural designs of the inertia ring and the hub and arranging the gear profile designs on the inertia ring and the hub respectively, the diameter and the width of the rubber ring are enlarged. The torque completely meets the product design requirements and the performance requirement of the vibration damper, and effectively avoids the running-off of the inertia ring and the hub in the complete vehicle reliability test.
Description
Technical field
The utility model relates to a kind of motor car engine vibration damper, especially a kind of torshional vibration damper structure.
Background technique
SQR371-1005070CA motor rubber shock absorber is made up of three branch parts as shown in Figure 2, i.e. inertia rings 1, wheel hub 2, rubber ring 3.Wherein rubber ring 3 is an interference fit between inertia rings 1 and wheel hub 2, and the major function of vibration damper is to reduce the crankshaft system torsional vibration, transmits motor head annex moment of torsion, and the big or small key of transmitting torque is the rubber ring size design.Among Fig. 2, the flute profile 4,5 of vibration damper complement is distributed in fully and causes the rubber ring size design to be restricted on the inertia rings, and the rubber diameter is designed to ￠ 75mm, and width is 31mm.Moment of torsion does not reach designing requirement, inertia rings and wheel hub disengaging accident in batches occur in the automobile reliability test.
Summary of the invention
The purpose of this utility model provides a kind of torshional vibration damper structure, can satisfy the design performance requirement of vibration damper, increases the moment of torsion of vibration damper complement, avoids occurring in the automobile reliability test accident of inertia rings and wheel hub disengaging.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: the torshional vibration damper structure, comprise inertia rings, wheel hub, rubber ring, it is characterized in that: described vibration damper profile of tooth is located at inertia rings outer surface and hub outside surface respectively, and rubber ring is located between inertia rings and the wheel hub.
To improvement of the technical scheme: the diameter of described rubber ring is 113-117mm, and width is 23.3-29.3mm.
Beneficial effect:
Torshional vibration damper structure described in the utility model by adjusting the structural design of inertia rings, wheel hub, is arranged in the flute profile design on inertia rings and the wheel hub, and the increasing diameter of rubber ring is 113-117mm greatly, and width is 23.3-29.3mm.Moment of torsion satisfies the product specification requirement fully, simultaneously also satisfies the vibration damper performance requirement fully, has effectively avoided the generation of inertia rings and wheel hub disengaging accident in the automobile reliability test.
