Detailed description of the invention
Fig. 1 is the exploded view of the utility model；
Fig. 2 is the sectional view of the utility model.
Specific embodiment
Below with reference to technical effect of the schematic diagram to the design of the utility model, specific structure and generation carry out it is clear,
It is fully described by, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment is this
A part of the embodiment of utility model, rather than whole embodiments are based on the embodiments of the present invention, those skilled in the art
Member's other embodiments obtained without creative efforts, belong to the range of the utility model protection.
As illustrated in fig. 1 and 2, a kind of belt pulley damper, including 3, two wheel hub 1, belt pulley 2, sliding bearing arcs are turned round
The outer iron 9 of spring 4, torsional spring flange 5, torsional spring housing 6, TVD wheel hub 7, rubber ring 8 and TVD, 1 periphery of wheel hub is provided with a convex
Circle 11, the fixation of sliding bearing 3 is set on the wheel hub 1, and is fastened on the wheel hub 1 by the convex circle 11, institute
It states belt pulley 2 to be set in outside the sliding bearing 3, there are two opposite protrusions for 2 inner wall of the belt pulley setting, described in two
Arc torsional spring 4 is separately positioned on two raised two sides, and through-hole is provided in the middle part of the torsional spring flange 5, and two sides are provided with outward
The wing wing 51 of extension, the torsional spring flange 5 is set in the end of the wheel hub 1, and is fixedly connected on one with the belt pulley 2
It rises, two wing wings 51 of 5 two sides of torsional spring flange are fastened on respectively between two arc torsional springs 4, and the torsional spring housing 6 is used for
Two arc torsional springs 4 are coated in the belt pulley 2；The TVD wheel hub 7 is by passing through the torsional spring flange 5
The dowel 14 of through-hole is fixed on one end of the wheel hub 1, and the outside of the TVD wheel hub 7 is closely arranged with rubber ring 8, described
The inner wall of the outer iron 9 of the TVD is affixed in rubber ring 8 is fixed.
The first washer 10, diaphragm spring 11 and second are disposed between the torsional spring housing 6 and the TVD wheel hub 7
Washer 12.Third friction washer 13 is arranged between the belt pulley 2 and the convex circle of the wheel hub 1.Two arcs are turned round
Arc inner spring 15 is arranged in spring 4 respectively.The arc inner spring uses arc steel spring.The arc inner spring uses arc
Shape steel inner spring, since start and stop mode is 48V motor, starting torque is big, starting the time it is short, so starting torsional impact compared with
Greatly, so that windup-degree is larger, therefore, arc inner spring is set in arc torsional spring, can solve the torsion of buffering larger angle
Square impact.The torsional spring flange 5 is fixed together by bolt with belt pulley 2.
Working principle explanation: the outer iron 9 of TVD is connect with dynamo belt, is rotated by iron 9 outside driven by engine TVD, due to
Rubber ring 8 is fixed to be affixed on TVD 9 inner wall of outer iron, and rubber ring 8 is also moved with iron outside TVD, under the frictional force of rubber ring 8, is driven
TVD wheel hub 7 rotates, since TVD wheel hub 7 is fixed together with wheel hub 1, so the case where TVD wheel hub 7 rotates
Under, wheel hub 1 is also with rotation；Belt pulley 2 is arranged on sliding bearing 3, when belt pulley 2 rotates under the drive of motor,
The wing wing for the torsional spring flange 5 being fixedly connected with belt pulley 2 respectively corresponds one end compression for stirring arc torsional spring 4, and is arranged in skin
Protrusion inside belt wheel 2 blocks the other end of arc torsional spring 4, and due to only one fixed frequency of arc torsional spring 4, this fixes frequency
Rate can reduce torque bring and fluctuate directly with mistake, the coupler that entire belt pulley system is formed by arc spring, with
Engine wheel hub is effectively isolated, the resonance generated when acting so as to avoid belt pulley and engine, the belt needed
Clamp force also accordingly becomes smaller.Lower belt tension means that lower resistance, final belt were driven in operation process
Friction in journey also just reduces.So pulley damper not only can be reduced the vibration of accessory drive system, it also can be to reduction
Oil consumption and CO2 emission are contributed.
Meanwhile the first washer 10, diaphragm spring 11 are disposed between the torsional spring housing 6 and the TVD wheel hub 7
Damping is formed, torsion capacity can be further adjusted by these components with second packing ring 12.
In conclusion with the additional selection of a torque bi-directional in coupler.In addition to drive belt transmission system
In attachment, the coupler also can be applied to be driven by belt in generator starting and propulsion functions internal combustion engine are provided.
In this case, belt transmission in torque stream in a reverse direction.Function function is dragged compared to current, those are needed more
The starting generator or pushing function of high torque, double dampers can provide asymmetric property curve.
It is the preferred embodiment of the utility model it should be noted that described above, the utility model not office
It is limited to above embodiment, as long as its technical effect for reaching the utility model with identical means, it is practical new all should belong to this
The protection scope of type.
