Definitions
- the invention relates to a chain guide element, in particular for a CVT transmission of a motor vehicle.
- Chain guide elements are known in CVT transmissions according to the prior art for guiding the chain and for damping strand vibrations of the chain.
- DE 102 03 941 A1 discloses a continuously variable conical-pulley transmission as a CVT transmission in which opposing chain guide elements are used to guide the chain and to dampen vibrations.
- the two chain guide elements are coupled to each other via a coupling mechanism, wherein the coupling mechanism allows an adjustment of the wrap and thus an adjustment of the path of the chain and allows an adjustment of the chain guide elements.
- the chain is only partially over the entire operating life of the chain guide element, which can lead to vibrations of the chain and thus to increased wear and unwanted noise.
- Guide rail for applying and guiding a chain comprising a coupling element, which has a receptacle for a holding element, wherein the holding element is formed as a cylindrical member having a securing element, which is received by the coupling element.
- the coupling element is formed by means of two pairs of tongues, with two respective tongues forming a pair receiving the holding element between them and receiving the securing element between the two pairs of tongues is.
- the tongues of a pair encompass the retaining element and the tongues of a pair then lie on one side of the securing element, such that the tongues of the two different pairs are each arranged on a different side of the securing element.
- the guide rail has at least one laterally extending substantially flat plate which is acted upon against the chain is particularly advantageous.
- This at least one flat plate is used to guide the chain and the reduction of Trumschwingungen because when the chain is applied to the plate, a vibration is reduced because the degree of freedom of the chain is reduced.
- the chain can be guided between these plates, which reduces the Trumschwingungen.
- the tongues protrude from the plate. It is advantageous if the tongues protrude approximately perpendicularly from the plate and thus form a receptacle for receiving the retaining element with the securing element. If the tongues are flexible, then the retaining element can be pushed and clipped between the tongues.
- the tongues have thickenings at their end regions which are directed toward one another in adjacent tongues of a pair.
- a kind of undercut for the clipping of the retaining element can be achieved.
- the securing element is a cylinder or a non-round, uniformly thick element which receives the cylindrical holding element.
- the cylinder or the non-circular element of equal thickness can have a bore which receives the cylindrical or tubular holding element.
- a non-round, even-thick element is a non-circular element, which however has the same diameter at each angle of rotation.
- the cylindrical holding element is a tube which serves the lubricating oil supply. It is also advantageous if the cylinder is provided with at least one bore which is aligned with a bore of the tube to serve the lubricating oil supply of the chain. Accordingly, the cylinder with its at least one bore, preferably also two holes, placed on the holding element designed as a tube, which in turn has at least one bore from which lubricating oil can escape, which is then passed to the cylinder and exits there.
- the guide rail has two spaced plates and two adjacent opposing walls which connect the two plates at the edge and thus form a channel for receiving the chain. This ensures a secure and defined guidance of the chain.
- FIG. 1 shows a schematic view of a chain guide element with holding element and securing element in a perspective view
- FIG. 2 shows a sectional view of a chain guide element with holding element and securing element
- Figure 3 is a sectional view of the chain guide element with holding element and securing element
- Figure 4 is a side view of the chain guide element.
- Figures 1 to 4 show a chain guide element 1 for a chain, in particular a conical-pulley belt drive in various views.
- the chain guide element 1 has a longitudinally extending guide rail 2 and a coupling element 3.
- the coupling element 3 serves to receive a holding element 4 for coupling the guide rail 2 to the holding element 4.
- the guide rail 2 of the chain guide element 1 is held for example in a transmission housing.
- the chain guide element 1 in this case has a guide rail 2, which has a first plate 5, a second plate 6, which are laterally connected by two spaced apart walls 7, 8, to form a channel 9, through which a chain is feasible.
- the plates 5, 6 have a lateral extension, which corresponds to the running direction of the chain, so that the plates 5, 6 can act on the chain over a portion of its extension and thus can reduce Trumschwingungen.
- the plates 5, 6 are divided into two in their longitudinal direction, wherein according to Figure 3 each half side of the plate 5 and the plate 6 is connected to a wall 7, 8 and forms a kind of half-shell 9, 10.
- the two half-shells 9, 10 thus formed are connected to each other by means of connecting means 1 1.
- These connecting means may be, for example, locking means.
- the parts may also be glued together, welded or otherwise connected.
- the holding means 4 is a cylindrical element, which is formed for example as a tube and can be arranged in a transmission housing.
- the retaining element 4 may also be a pipe of the lubricating oil supply of the chain.
- the holding element 4 in the region of the chain guide element may have an opening 13 for the outlet of lubricating oil for chain lubrication.
- a securing element 12 is connected, which is designed as a cylinder.
- the cylinder 12 is pushed over the cylindrical or non-round same thickness retaining element 4 and preferably with the retaining element 4 positively, frictionally and / or materially connected.
- the securing element 12 has a radius r which is greater than the radius r of the holding element 4, so that the securing element 12 protrudes radially beyond the holding element 4 and has lateral contact surfaces 14 for abutment of the coupling element 3.
- the coupling element 3 has four tongues 15, 16, 17 and 18, which are arranged in pairs and project from the plate 6.
- the tongues are aligned substantially parallel to each other.
- the tongues 15, 16 and 17, 18 of a pair embrace the retaining element 4 on both sides and take it between themselves. So that the retaining element does not escape again, the tongues 15 to 18 have a thickening 20 at their respective distal end region 19.
- the tongue becomes a kind of snap-action hook and the retaining element 4 can only come out of the region of the enclosure of the tongues under force application.
- the thickenings 20 of a pair of tongues are directed towards each other.
- the tongues 15 to 18 are arranged such that the distance between adjacent pairs of tongues approximately the distance of the axial extent of the securing element, so that the tongues preferably laterally against the securing element 12 and there against a side edge as a contact surface 14.
- a twisting of the chain guide element 1 on the holding element 4 is restricted or prevented transversely to the longitudinal axis of the holding element 4.
- the securing element 12 has at least one channel or opening 21, which is aligned with an opening 13 of the holding element, in order to effect a lubricating oil supply.
