Definitions
- the invention relates to a toothed chain formed by a plurality of pivotally interconnected links with at least one center strap and at least two on both sides of the center flap arranged cover plates, the cover plates and the center strap are connected to each other via at least two connecting members, and arranged between the cover plates and the middle lasche Inner plates, which connect the chain links pivotally.
- toothed chains are often used in motor vehicles and serve there as a control and aggregate drive in the internal combustion engine.
- the toothed chain wraps around the crankshaft, which here is the driving shaft, and at least one camshaft or camshaft adjuster, which here is the driven shaft, and thereby transmits the rotational movement of the crankshaft to the camshaft.
- the inner plates For transmitting the rotational movement, in particular, the inner plates have tooth-like projections directed inwards and / or outwards, which engage in corresponding receptacles of the drive disks of the driving and the driven shaft.
- the middle tabs are rotatably connected to the connecting members, which are preferably designed as bolts, and serve for the transmission of tensile force within the chain links.
- the cover tabs are arranged on both sides of the center straps and cover the tabs formed by the center straps and the inner straps side.
- the center flaps form a common sam with the cover plates and the links the chain links of the tooth chain.
- the inner flaps are arranged between the center flaps and the cover flaps and connect the chain links with each other.
- the inner plates are pivotally held with a game on the links. Due to the pivotable arrangement of the inner plates, the chain links can be pivoted relative to each other, so that the chain is movable and can adapt to different progressions between the driving and the driven shaft.
- the tooth chain can fulfill their function, therefore, different tabs have to be provided with different functions.
- the non-rotatable arrangement of the center lug on the connecting members has proven to be expedient, because in this way the tensile forces can be transmitted without wear within the chain links, thereby significantly increasing the service life.
- Another important aspect in the design of the silent chain is the effective joint surface between the inner plates and the links, which should be as large as possible in terms of a long service life of the silent chain.
- the object of the invention is to provide a toothed chain with a long service life and at the same time low production costs.
- a further increase in the effective joint surface can be achieved by the inner plates have openings through which the inner plates are pivotally supported on the connecting links, the inner plates are formed as stamped parts and are cut in the area of the openings. By regrooving the smooth cut portion can be further increased, so that the articular surface increases by about 30%.
- the width of an inner flap should be smaller than the width of the center flap. Since the center lug is non-rotatably connected to the connecting member, this has no joint function and can according to their main function to transmit the tensile forces occurring in the chain link, are dimensioned correspondingly wide. Furthermore, in order to minimize assembly costs, only a center strap should be used, which e.g. rotatably by an interference fit and additionally firmly connected in the direction of displacement on the connecting member with this. Since the inner straps are pivotally supported on the connecting links with a play, the assembly effort per inner strap is comparatively smaller, so that the use of thinner inner straps, which can be inexpensively punched, makes sense here. So that the acting tensile forces are transmitted between the chain links, a plurality of inner straps can be used, preferably two or more inner straps should be arranged on both sides of the center strap.
- the inner straps and the middle strap fulfill their function particularly well with the lowest possible manufacturing costs of the toothed chain, if the width of the inner straps 1, 2-1, 7 mm, preferably 1, 5 mm, and the width of the center strap 2, 0-2.5 mm, preferably 2.3 mm.
- the invention will be explained in more detail with reference to the single FIGURE 1.
- FIG. 1 shows a plan view of a toothed chain according to the invention.
- each chain link KG is formed from a center I lug M, two cover links D covering the chain links KG and two connecting links B designed as bolts.
- the center links M are connected in a rotationally fixed manner to the connecting links B and have the task of acting the tensile forces within the chain links KG transferred to.
- the center straps M are preferably pressed together with the connecting members B, so that they are secured against rotation on the connecting members and additionally secured against lateral slipping.
- the connecting links B on both sides of the center straps M each two réellela see 11 and 12 pivotally connected, which connect the chain links KG with each other. Due to the pivoting of the inner plates 11 and 12, the chain links KG are also designed to be pivotable relative to one another, so that the tooth chain as a whole can adapt to different progressions between the driving and the driven shaft.
- the width m of the center flap M is 2.3 mm
- the widths i1 and i2 of the inner flaps 11 and 12 are each 1.5 mm
- the width d of the cover flaps D is 0.9 mm.
- the center strap M is therefore the widest single strap and takes the largest tensile forces, while on both sides of the inner strap M and M at least two are provided so that they can be designed somewhat thinner despite the high tensile forces to be transmitted without their Load limit is exceeded.
- the cover plates D are finally the thinnest individual tabs, since their actual task is not in the transmission of tensile forces, but is to cover the chain links laterally and ensure the cohesion of the chain links.
- the inner flaps 11 and 12 can be cost-effectively punched due to the proposed width ratios, while still a sufficiently large joint surface for a long service life of the silent chain can be realized by the choice of a corresponding number of inner flaps. If necessary, the inner plates produced in the normal stamping process, at least in
- Section of the openings through which the inner plates 11 and 12 are pivotally mounted on the links B are recut, so that the smooth-cut portion and the joint surfaces are further increased.
