Abstract
The utility model provides a torsional damper structure, which comprises an inertia ring, a hub and a rubber ring, wherein the rubber ring is arranged between a contact surface of the inertia ring and the hub; one side of the hub is provided with a stepped hole; the inertia ring is arranged in the stepped hole; and a tooth profile of the damper is arranged on the outer surface of the hub. By adoption of the torsional damper structure, the requirement of design performance of the damper can be met, the torque of a damper assembly is improved, and an accident that the inertia ring is separated from the hub in a finished vehicle reliability test is avoided.
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
1005190D2-CW65-U motor rubber shock absorber is made up of three branch parts, i.e. inertia rings, wheel hub, rubber ring.Wherein rubber ring is an interference fit between inertia rings and wheel hub.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.The flute profile of existing vibration damper complement is distributed in and causes the rubber ring size design to be restricted on the inertia rings, and the rubber diameter is designed to ￠ 87mm, and width is 21.5mm.Moment of torsion does not reach designing requirement, in the stand reliability trial, inertia rings occurs and wheel hub comes off.
Summary of the invention
The purpose of the 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 in the automobile reliability test, occurring the accident that inertia rings and wheel hub come off.
In order to solve the problems of the technologies described above; The technological scheme of the utility model is following: the torshional vibration damper structure; Comprise inertia rings, wheel hub, rubber ring, rubber ring is located between the surface of contact of inertia rings and wheel hub, it is characterized in that: a side of said wheel hub is provided with step hole; Inertia rings is installed in the step hole, and the profile of tooth of vibration damper is located at the outer surface of wheel hub.
Improvement to technique scheme: the diameter of said rubber ring is φ 105 ± 0.1mm, and width is 15.8 ± 0.2mm.
Beneficial effect:
Use the described torshional vibration damper structure of the utility model; One side of wheel hub is provided with step hole; Inertia rings is installed in the step hole, changes original external inertia rings into built-in ring inertia rings structural design, makes the flute profile design arrange on the wheel hub respectively; The diameter of rubber ring can increase 105 ± 0.1mm for φ like this, and width is 15.8 ± 0.2mm.Moment of torsion reaches 600N.M from original 280N.M at present, satisfies the product specification requirement fully, through built-in inertia rings vibration damper and original structure vibration damper have been the torsional oscillation performance comparison test respectively.Test result: the maximum torsional oscillation amplitude of built-in inertia rings vibration damper is 0.117 °; The maximum torsional oscillation amplitude of original structure vibration damper is 0.192 °. built-in inertia rings vibration damper performance obviously is superior to the original structure vibration damper; The complete machine performance significantly promotes; Satisfy the vibration damper performance requirement fully, also stopped the generation of inertia rings and wheel hub disengaging accident in the automobile reliability test.
