Abstract
The invention provides a twisting and blending damper. An annular stepped groove consisting of an outer groove and an inner groove is arranged in a die cavity of a belt pulley body; a connecting member is in a cover-shaped structure with a center hole; the center hole of the connecting member is arranged in the inner groove of the annular stepped groove; a first elastic element is arranged between the inside of the end surface of the connecting member and the inner groove of the annular stepped groove; a cover body part of the connecting member is arranged in the outer groove of the annular stepped groove; an inertia ring is fixedly connected with the cover body part of the connecting member and is arranged in the outer groove of the annular stepped groove; and a second elastic element is embedded between the inertia ring and the connecting member. The twisting and bending damper provided by the invention has a simple structure and high reliability; the twisting vibration and bending vibration of an automobile engine can be improved simultaneously; the vibration can be reduced; the smoothness and the durability of automobile running can be improved; and early-stage fatigue failure of certain parts due to vibration and uncomfortable feeling and fatigue of drivers and passengers due to vibration within a certain range can be reduced.
Description
Technical field
The present invention relates to a kind of vehicular engine damping technology.
Background technique
The torsional moment that makes crankshaft rotating that engine crankshaft rotation produces, the disturbing moment of motor and produce the torsional oscillation vibration along the inertial force of cylinder centerline effect and the inertial force of substantially horizontal.Usually vibration damper is a final purpose to improve the torsional oscillation vibration, but motor also can produce vibration at bending direction under periodically variable power and moment loading.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of existing technology and provide a kind of simple for structure, reliability is high, improves motor car engine simultaneously and reverses the twist and warping vibration damper with flexure vibrations.
Technical program of the present invention lies in: be provided with the ring-shaped step groove of forming by a water jacket and an inside groove in the pulley body die cavity; Link is a cover-shaped structure of band center hole, and the center hole of link is loaded in the inside groove of ring-shaped step groove; Between the end face inboard of link and the inside groove of ring-shaped step groove first elastic element is housed; The lid of link is partly inserted in the water jacket of ring-shaped step groove; The lid of inertia rings and link partly is fixedly connected, and places the water jacket of ring-shaped step groove; Second elastic element is embedded between inertia rings and the link.
Said first elastic element is an annular.
Said second elastic element is a tubular.
Gapped between the water jacket of said inertia rings and pulley body ring-shaped step groove.
Be useful on the recessed or protruding structure that connects with link on the said inertia rings, convexity corresponding with it or recessed structures are arranged on link.
Said inertia rings is loaded on the lid inboard partly of link.
Said inertia rings is loaded on the lid outside partly of link.
For reducing the vibration of bending direction, the present invention proposes two kinds of technical solutions, the difference of two kinds of schemes is the position of inertia rings.Inertia rings is positioned at the inboard of the maximum cylindrical of link in scheme one, and the maximum outside diameter of inertia rings is less than the maximum outside diameter of link; Inertia rings is positioned at the outside of the maximum cylindrical of link in scheme two, and the minimum diameter of inertia rings is greater than the maximum outside diameter of link.
The present invention is simple for structure; Reliability is high; Can improve simultaneously that motor car engine is reversed and flexure vibrations; Can reduce vibration, improve the smoothness and the durability of automobile running, minimizing causes the beginning of fatigue failure of some parts because of vibration and because the vibration of certain limit makes the uncomfortable and tired of driver and passenger's generation.
