Spring 236a diameter, damping spring 236a outside is set to form certain thickness rubber pattern.
As shown in Fig. 6 a-6b, the manufacturing process of rubber damping spring 236 is：
1) casting mold is prepared, the casting mold includes fixing mould 252 and moves moulds 254, fixing mould 252 and moves
Groove is respectively equipped with moving mold 254, it is described to move moulds 254 provided with the rubber inlet I connected with groove thereon；
2) damping spring 236a is put into the groove of fixing mould 252, and is in coil spring state, then will moved moulds
254 with the matched moulds of fixing mould 252, the type for so making damping spring 236a be placed in fixing mould 252 and move moulds between 254
In chamber C, as shown in Figure 6 a；
3) pressurizeed by the rubber inlet I to move moulds on 254 into die cavity C injection rubber；
4) it is stripped after rubber-moulding is rubber bodies 236b, completes being integrally formed for damping spring 236a and rubber bodies 236b
Technique.
The die cavity C internal dampings spring 236a peripheral bonds of mould maintain to have to inject rubber under certain interval state, therefore
Damping spring 236a peripheries form certain thickness rubber membrane, and uniform diameter.The diameter for the rubber bodies 236b being molded is more than
Damping spring 236a diameter, damping spring 236a outside is set to form certain thickness rubber pattern.
Rubber damping spring 236 is used to buffer torsion transmission drastically, and rubber damping spring 236 such as will by deficiency setting
During the torsion asked, certain cushion effect is only provided；During by more than setting value torque value, there is provided bigger than certain cushion effect is slow
Impulse force, and the torsion being subject to is bigger, it is possible to provide bigger cushion effect.
As shown in fig. 7, rubber damping spring 236 by insufficient setting value To torsion when, there is provided the cushion effect of certain value,
Corresponding torsion increase ratio, the increase ratio of the anglec of rotation of clutch plate body 235 is also certain, i.e. the rotation of clutch plate body 235
Gyration and the torsion that rubber damping spring 236 is subject to are linear；But when conversely by more than setting value To torque value,
The higher cushion effect (being more than above-mentioned definite value) of offer, relative torque forces T increase ratio, the anglec of rotation A's of clutch plate body 235
Increase ratio to reduce.
Certainly, the setting value To of rubber damping spring 236 be able to can be changed by design factor, can also pass through damping bullet
Spring 236a and rubber bodies 236b material are adjusted making.
Operation principle of the present utility model is：
The effect of the power delivery mode and rubber damping spring of clutch driven disc assembly provided by the utility model, pass
The torsion for being handed to friction plate 240 promotes rubber damping spring by wavy spring piece 241, clutch plate 232 and damper disk 233
236 one end, after rubber damping spring 236 enters row buffering to the torsion of transmission, the other end of rubber damping spring 236 pushes away
Dynamic clutch plate body 235, drives clutch plate body 235 and hub plate 234 to rotate, while be connected with the spline of hub plate 234
The main drive shaft of gear can also rotate.Now, when rubber damping spring 236 transmits insufficient setting value To torsion, turn round
Power is transmitted after being reduced by damping spring 236a to the elastic force of circumferencial direction spring.When transmitting the torsion more than setting value To,
Torsion not only by elastic force from damping spring 236a to circumferencial direction spring reduce while, with rubber bodies 236b in itself one
When elastic energy the mode mode that stores and discharge reduce after transmit, therefore can reduce more.Therefore, using with rubber
The clutch driven disc assembly of damping spring 236, in the situation by excessive torsion, punching is absorbed by damping spring and rubber
Transmitted while hitting, outstanding shock-absorbing capacity can be maintained, vibration and noise can be reduced.
Embodiment of the present utility model is the foregoing is only, is not intended to limit the scope of protection of the utility model.It is all
Made within spirit of the present utility model and principle any modification, equivalent substitution and improvements, extension etc., are all contained in this reality
With in new protection domain.
