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 100 17 005 A1 discloses a continuously variable conical pulley belt transmission as a CVT transmission, in which a chain guide element is formed as a receiving rail with an upper and a lower rail, which are connected to each other via at least one lateral arm as a spacer, wherein the Chain between the two rails runs in the longitudinal direction of the rails.
- the chain guide element is disposed within the transmission between the two conical disks and it is arranged pivotable and translationally movable via a combined pivot and translation bearing, so that the chain guide element can adapt to the respective course of the chains, if the transmission ratio by changing the radii of the Chain in the conical disks is changed.
- the chain guide element has a downwardly open receptacle below the lower rail, which can be placed on a pipe or a bolt, which is or arranged parallel to the axis of the conical disks between them. Below in this context means directed towards the median plane passing through the axes of the two conical discs.
- the chain guide element When the chain changes from an extreme position to another extreme position, the chain guide element describes a movement which consists of a composite movement of a rotational movement about the guide tube and a translational movement.
- the space used by the recording arranged under the rails, the space for the rails and the connecting element is limited, which means that they must be designed as such relatively narrow, resulting in their rigidity negative acts. This also has negative effects on the damping of first and second order front and back vibrations and on the production
- An embodiment of the invention relates to a chain guide element having a first rail and a second rail, which is spaced from the first rail, wherein on both sides of the rails in each case a lateral connecting element is arranged, which connect the two rails together, wherein first bearing means are provided for pivotably and translationally supporting the rails by means of second bearing means, the first bearing means being arranged on the lateral connecting elements and the second bearing means cooperating with the first bearing means arranged laterally of the rails.
- bearing means are provided laterally of the rails and thus the side of the chain, so that more space is available for the rails and the connecting element and the rails and the connecting element can be made more massive which has a positive effect on the rigidity of the rails and affects the manufacturing.
- first and the second bearing means are arranged substantially at the height of the chain in the chain guide element.
- first bearing means each have a receptacle, in which in each case a projection of the second bearing means engages or the first bearing means each have a projection which engages in each case in a receptacle of the second bearing means.

- the chain guide element can rotate about the projection by means of the receptacle. If the receptacle is elongate, a radial compensation can also take place.
- the projection and the receptacle are arranged substantially at the level of the chain in the chain guide element.
- the second bearing means are arranged connected to an axis, which is arranged spaced from the first and second bearing means.
- the second bearing means can be connected via the axle with a transmission housing. If the axis runs in the area between the conical disks of the conical-disk belt transmission, space can also be saved.
- the second bearing means protrude as projections from the axis, wherein the projections are formed as a pin extending in the axial direction. The intervention in the recordings then takes place in the axial direction.
- the second bearing means protrude as projections from the axis, wherein the projections are in the radial direction extending pan-like slices.
- engagement in the receptacles can essentially take place from the radial direction.
- the second bearing means are formed as a pocket, which are aligned open in the axial direction and the first bearing means are formed from projections which engage in the pockets in the axial direction is particularly advantageous.
- the radial extent of the receptacle is greater than the radial extent of the protrusion engaging in the receptacle.
- a projection has a circumferential annular bead, wherein a receptacle has an annular groove for receiving the one bead.
