Abstract
The invention discloses a crank shaft shock absorber which comprises a belt wheel, a hub a, a hub b and an inertia ring, wherein the hub b is sleeved outside the hub a, the hub a and the hub b are in close fit, the belt wheel is sleeved at the exterior of the hub b, a rubber sheet is arranged between the hub b and the belt wheel, the inertia ring is installed on the hub a, and a rubber gasket is arranged between the inertia ring and the hub a. The crank shaft shock absorber provided by the invention has the characteristics that the cranked combined type shock absorber has favorable shock-absorbing performance, the service life of the crank shaft of an engine can be improved and the vibration and noise of the engine can be reduced.
Description
Technical field
The present invention relates to auto parts and components, be specifically related to a kind of vibration damper.
Background technique
Automobile engine crankshaft is very important parts, and its manufacturing process is complicated, and quality requirement is high; When engine operation, the vibration of bent axle is mainly the vibration of torsional direction, and bending direction also possibly produce vibration simultaneously; How to reduce the vibration of bent axle; Be one of important content of engine crankshaft design, the conventional means that reduces crankshaft vibration is at the crankshaft front end mounting dampers, at present in the Crankshaft System of Automobile Engine system extensive use be rubber damping formula single-stage torsional vibration damper; Its damping value is less than normal, does not usually reach the vibration damping requirement of crankshaft system.
Summary of the invention
The objective of the invention is to overcome above-mentioned not enough problem, a kind of vibration damper is provided.
The present invention for realizing the technological scheme that above-mentioned purpose adopted is: a kind of vibration damper; Comprise belt wheel, wheel hub a, wheel hub b, inertia rings, said wheel hub a is with wheel hub b outward, and both are drive fit; The said wheel hub b outside is with belt wheel; Between said wheel hub b and the belt wheel sheet rubber is housed, on the said wheel hub a inertia rings is installed, between said inertia rings and the wheel hub a rubber pad is housed.
Characteristics of the present invention are: bending combined type vibration damping device, have the favorable damping performance, and improved the life-span of engine crankshaft, reduced the vibration and the noise of motor.
Description of drawings
Fig. 1 is a schematic representation of the present invention.
Wherein: 1, belt wheel 2, rubber parts 3, wheel hub b 4, wheel hub a 5, rubber pad 6, inertia rings.
Embodiment
As shown in Figure 1, the present invention includes belt wheel 1, wheel hub a4, wheel hub b3, inertia rings 6, wheel hub a4 is the link of vibration damper and crankshaft front end; Said wheel hub a4 is with wheel hub b3 outward, and both are drive fit, so wheel hub b3 can be considered the part of wheel hub a4; The said wheel hub b3 outside is with belt wheel 1, between said wheel hub b3 and the belt wheel 1 sheet rubber 2 is housed, said belt wheel 1 double as twisting inertia ring; Form torsional vibration damper with rubber parts 2; On the said wheel hub a4 inertia rings 6 is installed, between said inertia rings 6 and the wheel hub a4 rubber pad 5 is housed, said inertia rings 6 is formed crooked vibration damper with rubber pad 5.
The above; Be merely the preferable embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or change according to technological scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
