embodiment:
With reference to accompanying drawing, a kind of synchronous two-way oil damping structure of automatic clutch, mainly by input component 1, sliding component 2, damping plug screw 3, end ring 4 forms, it is characterized in that: damping hole is positioned on damping plug screw 3, on damping plug screw 3, be processed with screw thread, together with damping plug screw 3 passes through scyewed joint with sliding component 2, on sliding component 2, be provided with many places phase oil through, these oilholes communicate with the damping hole on damping plug screw 3, in the time that damping structure works, lubricating oil can pass through many places oilhole, damping hole, enter another oil pocket from an oil pocket, flow of oil is through oilhole, in the process of damping hole, produce damping force, damping force acts on sliding component 2, sliding component 2 circumference are provided with multiple tapped holes of circumference uniform distribution, with the damping plug screw 3 of tapped hole equal amount by tapped hole and sliding component 2 scyewed joint.
While adjusting damping characteristic, can there be three kinds of modes:
1. change damping hole size: because damping is arranged on damping plug screw, only need to change the damping plug screw in different damping aperture, can reach the object that changes damping hole size;
2. change damping hole quantity: because sliding component is preset with multiple tapped holes, in each tapped hole, all there is damping plug screw, in the time that needs change damping hole quantity, can selectively use the damping plug screw with damping hole, in remaining tapped hole, place the not damping plug screw with damping hole, while not establishing damping hole on damping plug screw, be equivalent to a pure plug bolt, mean that damping oil circuit is blocked extremely, lubricating oil this oil circuit of can not flowing through, can not form damping force, reaches the object of damping hole quantity.
1. and 2. 1. and 2. 3. combine operational mode: integrated use mode, changes damping hole size simultaneously and changes damping quantity, reaches the object of adjusting damping characteristic.
Damping plug screw is arranged on the outside accessible place of sliding component, without decomposing clutch, can conveniently adjust.
Simplify damping hole adjustment operation, reduce workload, reduce labor intensity, can play bidirectional damper effect simultaneously, not only can effectively slow down the shock that clutch's jointing process sliding component in latter stage produces, and in the time there is the fluctuation of load, the damping in throw-out-of clutch direction can also prevent the drop out of gear that clutch is instantaneous.
In Fig. 1, traditional double is to damping structure, and input component 1, sliding component 2, end ring 3 have formed bidirectional damper structure jointly.The M face of input component 1, the P face of sliding component 2 and end ring 3 form damping oil pocket A, B, and input component 1 is provided with damping hole, and damping hole circumference uniform distribution is on input component 1.Damping force can be by changing damping hole size and damping hole quantity regulating.In the time that needs are adjusted damping characteristic, need to change damping hole size or change damping hole quantity.Changing damping hole when size, can only on the basis of former damping hole, carry out aperture increase, and can not reduce, and this process is irreversible, once damping aperture need to reduce, adjust and become difficulty.Change damping hole quantity and have equally the problems referred to above.When adjusting damping hole size or changing damping hole quantity, in operation, there is inconvenience.Repeatedly revise because damping characteristic adjustment is one the process of adjusting, may have multi-pass operation, and damping hole is positioned at damping structure inside, therefore adjust damping hole at every turn, clutch all must be decomposed, the workload of multi-pass operation is larger.
In Fig. 2, bidirectional damper structure of the present invention, input component 1, sliding component 2, damping plug screw 3, end ring 4 have formed bidirectional damper structure jointly.The M face of input component 1, the P face of sliding component 2 and end ring 3 form damping oil pocket A, B, and damping hole is arranged on damping plug screw 3.
Damping force can be regulated by the mode that changes damping hole size, change damping hole quantity or be used in combination, and changes the spiral plug screw in different damping hole, can adjust easily damping force.
Damping mechanism working principle is as follows:
When clutch joint action starts, sliding component 1 slippage to the right, be as the criterion with direction shown in Fig. 2, damping oil pocket A volume reduces, at P, before M face closure, lubricating oil directly enters damping oil pocket B by damping oil pocket A, at this moment the oilhole on the damping hole on damping plug screw 3 and sliding component 2 without flow of oil, do not produce damping force, sliding component 2 continues slippage to the right, P, after M face closure, lubricating oil can not directly enter damping oil pocket B by damping oil pocket A, but damping hole on overdamping plug screw 3, oilhole on sliding component 2 enters damping oil pocket B, and then produce damping force, damping force has slowed down the slip velocity of sliding component, therefore can effectively reduce vibration and the shock of sliding component, play buffer function.
Damping structure is in clutch's jointing process, and diverse location is as shown in Fig. 2 ~ Fig. 5.
After clutch engages, the position of damping structure as shown in Figure 5.Clutch is in engagement positio normal course of operation, if there is fluctuation in load, in the time there is the trend of slippage left in sliding component 2, lubricating oil in damping oil pocket B is by damping hole, oilhole, flow into rapidly in damping oil pocket A, the damping force producing hinders sliding component 2 and continues slippage left, makes sliding component 2 returning position again, thereby has effectively prevented the drop out of gear that clutch is instantaneous.
In the time that clutch need to be thrown off, continue to strengthen the moment of torsion of clutch output terminal, in the time that clutch output terminal moment of torsion is greater than damping force, 2 of sliding components start slippage left.The disconnecting process of clutch is contrary with engaging process, and in throw-out-of clutch process, damping structure present position is contrary with present position in clutch's jointing process.M emaciated face at the P of sliding component 2 face and input component 1 is opened before operating position, oilhole on damping hole, sliding component 2 that lubricating oil is flowed through damping plug screw 3 from damping oil pocket B all the time enters damping oil pocket A, and produce damping force, when the M emaciated face of the P of sliding component 2 face and input component 1 opens and closes co-bit postpone, lubricating oil directly enters damping oil pocket A from damping oil pocket B, no longer produces damping force.
