Definitions
- the present invention relates to a method for producing an elastic force transmission member, in particular for transmitting torques, for example in a motor vehicle or in an industrial application, wherein the force transmission member provided with at least two receiving openings for connection with power transmission components, an elastomeric body and at least one embedded in the elastomeric body insert loop is.
- the invention further relates to an elastic force transmission member made by this method.
- Such power transmission members are known in the art.
- the document DE 10 2005 003 459 B3 shows a flexible disc, as it can be used in a drive train of a motor vehicle or in a steering column.
- Such flexible discs have a plurality of openings defined by bushes.
- these bushes are wrapped in pairs of several Schiingenveren so that between two adjacent bushes tensile forces can be transmitted.
- the bushes and Schiingenwovene are embedded in an elastomeric body.
- torques can be transmitted between two shaft sections to be connected to each other, wherein in each case three of the bushes are connected to a shaft portion and the respective intermediate bushes with the other shaft portion.
- Such a flexible disk can compensate for an axial offset and an angle between the two shaft sections due to gimbal deformation.
- Such joint discs are characterized in a correspondingly complex production by a long service life despite their gimbal load during operation.
- first single ventilation spines are positioned in the mold.
- These ventilation mandrels can already be formed on the mold or be displaceable in the form of slides in the mold.
- the ventilation mandrels create ventilation openings in the elastomer body, through which gas or air inclusions can escape from the elastomer body. This can already be done during vulcanization, for example, when the ventilation mandrels are hollow or when they are pulled out of the mold during vulcanization. Alternatively, this can also be done after vulcanization, for example, by the ventilation mandrels pulled out of the mold or the entire mold is removed.
- any ventilation opening already ensures a certain venting effect.
- the inventive method provides that the ventilation mandrel penetrates with its free end into the insert loop. Care must be taken to ensure that the ventilation mandrel does not injure the insert loop itself, but only ensures that the ventilation opening created thereby actually extends as far as the insert loop and possibly into it.
- the ventilation mandrel has a conical shape at least in sections. Furthermore, it is possible that the ventilation mandrel is provided at its free end with a taper or tip. This also makes it easier that the vent mandrel penetrates sufficiently deep into the insert loop.
- a development of the invention provides that the ventilation mandrel is solid or formed with a cavity. If the ventilation mandrel is solid, venting can only take place after removal of the ventilation mandrel. If it is formed with a cavity, the venting can take place through the cavity of the ventilation mandrel.
- the insert loop is formed by a thread package, wherein the ventilation mandrel projects into the thread package by displacing individual threads.
- a violation of individual threads of the thread package is inventively to avoid.
- a development of the method according to the invention provides that the at least one ventilation opening is closed after the venting with elastomeric material or a foreign material.
- an opening-free power transmission member can be obtained, in which a sufficient ventilation has taken place on the originally formed ventilation openings, which were subsequently closed.
- a subsequent closing of these vents is also considered when a single vent mandrel was removed during vulcanization, so that it could come to a vent, and then closes during vulcanization, the originally formed vent with vulcanizing elastomeric material.
- the invention further relates to an elastic force transmission member, in particular for transmitting torques in a motor vehicle or in an industrial application, wherein the force transmission member is provided with at least tworacöffnun- conditions for connection with power transmission components, an elastomeric body and at least one embedded in the elastomeric body insert loop. It is provided that the force transmission member is provided with at least one vent opening extending through the elastomeric body to the at least one insert loop out.
- the ventilation opening has at least sections conical course.
- the force transmission member has a flexible disc with a plurality of circumferentially arranged insert loops, which are embedded in the elastomer body, wherein at least one insert loop, preferably each insert loop, at least one vent is associated.
- the individual ventilation openings can be arranged only on one side of the flexible joint or on two opposite sides.
- the ventilation opening is arranged in each case in a central region of the insert loop between two receiving openings.
- the force transmission member can have a force transmission link with at least one insertion loop embedded in the elastomer body, wherein the ventilation opening is arranged in a middle region of the insertion loops between two receiving openings.
- Such insert loops can be provided for example in coupling arrangements, for example so-called tab couplings.
- the at least one insert loop can each be formed by a thread package.
- Figure 1 is a plan view of a flexible disc according to the invention.
- Fig. 2 is a sectional view taken along section line AA of Fig. 1;
- FIG. 3 shows a plan view of a force transmission link according to the invention
- FIG. 4 shows a sectional view along the section line B-B from FIG. 3.
- a trained as a flexible disk power transmission member is shown in front view and generally designated 10.
- This comprises a plurality of bushes 12, which are arranged with their centers on a circular path K.
- the bushes are embedded in a rubber elastic elastomer body 14.
- each have a plurality of textile thread packages 16, 18 are embedded, which are enclosed by the elastomer composition.
- FIG. 2 It can be seen there that, for example, around the bushes 12i and 12 2 (see FIG. 1) two thread packages 16i and 16 2 are arranged, which run in different planes. Furthermore, a central thread package 18i is wrapped around the bushings 12 3 and 12 4 .
- the thread packages 16 ensure a tensile force transmission between two adjacent bushes.
- the embedding in the elastomeric mass 14 provides for dimensional stability of the joint body and also for the possibility of elastic deformation to (not shown) to transmit, for example, a torque between two shaft portions, wherein the first shaft portion to the jacks 12i, 12 3 and 12 6 and the second shaft portion is coupled to the sockets 12 2 , 12 4 and 12 5 .
- the flexible disc 10 allows in a conventional manner, a compensation of a certain axial offset between the shaft sections and a compensation of an inclination of these shaft sections to each other by gimbal movements.
- Vents 20 which are incorporated in the elastomeric body 14 during manufacture and extending from the outer environment to the respective Schiingenveren 16i, 16 2 and 18i.
- the Schiingenwovene are not isolated from the ambient atmosphere, but connected to this via the ventilation openings 20.
- These vents 20 serve to ensure during manufacture, in particular during the vulcanization of the elastomer body, that gas or air inclusions, which have resulted in injecting the elastomeric material into a mold on the Schiingenveren can escape from the interior of the flexible disk 10 and so a life-reducing weakening of the flexible disc due to these gas inclusions can be avoided.
- These vents 20 therefore extend to the Thread packages 16, 18 zoom in, preferably even in this. They are achieved in the manufacture of this joint disc by suitable mandrels.
- Fig. 3 shows a power transmission plate 50, which is used for example in a tab coupling. This also has two bushes 52i, 52 2 , around which a loop package 54 (see FIG. 4) is guided around for the transmission of traction.
- the Schiingenzig 54 and the bushes 52i and 52 2 are embedded in an elastomeric body 56.
- vent 58 which is introduced into the force transmission plate 50 for the same purpose, as described with reference to FIGS. 1 and 2 for the flexible disc.
- the vent 58 extends through the elastomeric body 56 toward the thread package 54 and into it. It has conical course at least in sections in its inner area. It should be noted that the ventilation opening 58 does not hurt individual threads of the thread package 54, but rather displaces them only during production. Significantly, the vent 58 provides communication between the loop pack 54 and the environment to allow for venting and venting of air or gases trapped in the filament package 54 during injection of the elastomeric material.
