Description
Technical field
The utility model relates to driving wheel field of components, and in particular to a kind of engine drive pulley.
Background technique
Automobile engine is the main inherent source that car body generates vibration, and the twisting vibration of engine can not only cause gap
It hits and generates impact vibration, also result in the breakage of shaft.The drive pulley of automobile engine is by matching with belt
It closes to transmit power, the power that crankshaft exports is passed into camshaft, drives timing system.Automobile engine drive pulley
Design directly affects torsion shake, noise and transmission efficiency of engine etc..The engine belt pulley of casting because own wt is heavier,
In the case where high engine speeds rotate and its travel vibration, the components such as bearing, gear and camshaft of engine can be easy to aging, greatly
The big service life for shortening engine.Due to the belt pulley heavier-weight of casting, reduces the power of engine, will increase and start
The oil consumption of machine.The drive pulley rigidity of the prior art, damping adjusting are limited, and rubber damping characteristic is unable to reach the vibration damping of needs
Effect.
Utility model content
In view of this, adjustable rigidity range is more the purpose of this utility model is to provide a kind of engine drive pulley
Greatly, frictional damping can also be provided, and then adjust damping size, belt train can be optimized according to different engine output characteristics and turned round
Vibration, reaches that adjustable extent is wider, can the more different characteristics of matching optimization disc-coupled vibration.
Engine drive pulley, including front cover, rear cover, damping part and the connection cooperated with engine crankshaft transmission
Seat, the front cover and rear cover are all set in attachment base and are assembled to form the cavity for accommodating the damping part, the connection
It is provided on seat when crankshaft is reversed for the regulating device of damping to be adjusted with damping part cooperation.
Further, the damping part is spring.
Further, the spring is arc spring.
Further, the regulating device is to be fixedly connected with attachment base and when attachment base is reversed for stirring the spring
Shift fork.
Further, the shift fork is towards away from rear cover curving and extending radially outwardly along attachment base.
Further, the annular groove for assembling with the rear cover is formed on the end face of the front cover.
It further, further include for carrying out the damping adjustment device that axial compression is used for adjustment spring damping to spring.
Further, the damping adjustment device includes bolt, butterfly spring and damping gasket, it is described be bolted crankshaft and
For butterfly spring and damping gasket to be pressed in spring.
The utility model has the beneficial effects that the utility model drive pulley adjustable rigidity range is bigger, benefit be can also be provided
Frictional damping, and then damping size is adjusted, belt train torsional oscillation can be optimized according to different engine output characteristics, reach adjustable
Range is wider, the disc-coupled vibration of the energy more different characteristics of matching optimization.
Detailed description of the invention
The utility model is further described with reference to the accompanying drawings and examples:
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Fig. 1 is the structural schematic diagram of the utility model, engine drive pulley, including front cover 1, rear cover 2, damping part
And the attachment base 8 with engine crankshaft transmission cooperation, the front cover 1 and rear cover 2 are all set in attachment base 8 and are assembled to form use
It is used to match with the damping part when crankshaft reverses in being provided on the cavity for accommodating the damping part, the attachment base 8
Close the regulating device that damping is adjusted.The utility model drive pulley adjustable rigidity range is bigger, adjusts more stable.
In the present embodiment, the spring 3 is arc spring.Entire assembly space environment is adapted to using arc spring,
It is compact-sized.
In the present embodiment, the regulating device stirs institute to be fixedly connected with attachment base 8 and being used for when attachment base 8 reverses
State the shift fork 4 of spring 3.By the way that shift fork 4 is arranged, being overturn suddenly in attachment base 8, attachment base 8 drives shift fork 4 or so to stir spring 3,
Play the role of damping.
In the present embodiment, the shift fork 4 makes to dial towards 2 curving of rear cover and extending radially outwardly along attachment base 8 is deviated from
Fork 4 to stir effect more preferable, be more easy to control.
The annular groove for assembling with the rear cover 2 is formed in the present embodiment, on the end face of the front cover 1, is conducive to installation, dress
It is more stable with effect.
It further include adjusting dress for carrying out the damping that axial compression is damped for adjustment spring 3 to spring 3 in the present embodiment
It sets.The present embodiment is by setting damping adjustment device, so that frictional damping can also be provided, and then adjusts damping size, Ke Yigen
Optimize belt train torsional oscillation according to different engine output characteristics, it is wider to reach adjustable extent, can the more different characteristics of matching optimization
Disc-coupled vibration.
In the present embodiment, the damping adjustment device includes bolt, butterfly spring 5 and damping gasket 6, described to be bolted
Crankshaft and for butterfly spring 5 and damping gasket 6 to be pressed in spring 3, bolt is for while connecting crankshaft, also using spiral shell
The adjusting of bolt torque controls pressing force, and then adjusts damping size, can be excellent according to different engine output characteristics
Change belt train torsional oscillation, reach that adjustable extent is wider, can the more different characteristics of matching optimization disc-coupled vibration.
Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this
The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model
It encloses, should all cover in the scope of the claims of the utility model.
