Description
Technical field
This utility model relates to a kind of flywheel, specifically a kind of damping type flywheel.
Technical background
General damping type flywheel is assembled between engine crankshaft and transmission input shaft, because of electromotor
Explosion stroke does not recurs, but interim generation, the power accompanying rotation causing crank axle to export is shaken
Dynamic, therefore to the device reducing this type of whirling vibration stably to export revolving force and existing.
Recently in order to can correspondence rotational velocity range widely, stable accommodate various because of the torsion of load
Change, uses the trend that double mass flywheel becomes.This type of double mass flywheel comprise one-level flywheel, two grades
Flywheel, driving dish, coil spring and bearing etc., one-level flywheel is connected to the crank axle of electromotor, two grades
Flywheel is connected with one-level flywheel can be rotated against by bearing, and is driven by clutch input power
Dish is assembled in two grades of flywheel sides, driving dish and coil spring end thereof contacts, coil bullet by fixed component
The other end of spring contacts with one-level flywheel.When the one-level flywheel being connected with crank axle receives the torsion of electromotor
During power, after the decay of coil spring and damping, it is transferred to two grades of flywheels by driving dish.Therefore,
The torsion that one-level flywheel is subject to changes with angles shifts and the torsion of electromotor, and contrary two grades of flywheels are subject to
Torsion by the decay of coil spring and and lid between damping by friction be changed to stable torsion and be transferred to speed change
Case.Coil spring is contained in a pair spring guide, and this type of spring guide circumferentially direction is arranged in one-level
Between flywheel stop tip and the driving dish protuberance being assembled in two grades of flywheels.Spring guide has
Accommodate the holding tank of coil spring end, for supporting propping up of coil spring end elastic force bottom above-mentioned holding tank
Support structure.Coil spring is contained in two kinds of spring guide holding tanks, and flexibly supports at the bottom of holding tank
The structure in face.And press: one-level flywheel, one-level flywheel stop tip, driving dish protuberance, driving dish and two
Level flywheel, this type of order transmission revolving force.Further, general coil spring is pressurizeing contraction-like because of stop tip
Torsion is transmitted under state.Therefore, increase the amount of contraction of coil spring from the torsion change of one-level flywheel transmission,
Produce cushioning effect, so reducing whirling vibration and reducing noise.But, one flies to being used in damping type
The spring guide material of wheel uses plastic material injection mo(u)lding to form, because damping type flywheel operates repeatedly, and line
Coil spring end with high loading repeatedly contact spring guide bracket inside, make spring guide durability decline, inner side
Abrasion, causes there is the problem shortened service life.

300 is low, and therefore one-level flywheel 200 is received through the coil spring 400 power by two grades of flywheels 300 on the contrary.
But now such as foregoing, the impact of two grades of flywheels 300 is entered by the elastic force of coil spring 400 self
Row decay, makes to slow down smoothly.
This utility model molding inside spring guide 500 strengthen inside the enhanced portion of intensity, even if damping
Formula flywheel operates repeatedly, inside the contact spring guide bracket 500 repeatedly of coil spring 400 end, also can prevent from holding
Groove 510 inside bottom surface of receiving is worn and torn, and increases the life-span of product.
The foregoing is only embodiment of the present utility model, be not intended to limit protection of the present utility model
Scope.All made within spirit of the present utility model and principle any modification, equivalent substitution and improvement,
Extensions etc., are all contained in protection domain of the present utility model.
