Definitions
- Clamping device for at least two traction mechanism drives
- Tensioning device for traction mechanism drives such as belt drives, chain drives or the like, with at least two tensioning arms having tensioning rollers at their free ends, which are pivotably mounted on a machine housing, in particular an internal combustion engine housing, and are preloaded in the sense of a displacement of the tensioning rollers in the tensioning means tensioning direction.
- Such a generic tensioning device is known from DE-198 49 659 A1.
- the tensioning arms are mounted at various points on the machine housing, carry tensioning rollers at their ends and have levers connected to the tensioning arms, between the ends of which a tensioner is arranged.
- This configuration of the tensioning device is intended to exert forces on both traction element runs of the traction mechanism drive which differ depending on the position and length of the levers and influence one another. It is therefore a special tensioning device for a traction mechanism drive.
- the object of the invention is therefore to provide a tensioning device for traction mechanism drives, which is suitable for tensioning two or more traction mechanism drives, this being done with little space and cost.
- the object of the invention is achieved in that the one tensioning roller is in operative connection with a first traction mechanism drive and in that the further or further tensioning rollers are in operative connection with further tension means drives.
- the one or more traction means drives are arranged offset to the first traction means in the axial direction of the drives, and the tensioning rollers are correspondingly offset from one another.
- the clamping arms can be biased against each other and / or against the machine housing.
- the bias or the pretensioner can be designed in any manner. It is possible to use spring / damping elements that support the clamping arms against each other. However, it is also possible to use spring / damping elements which individually support and dampen each tension arm with respect to the machine housing or which initially support one tension arm with respect to the machine housing and the further tension arm with respect to the first-mentioned tension arm. In this latter design, it is advantageous if the spring / damping elements are matched in terms of force and damping accordingly, since when the two clamping arms are ultimately supported against one another and then the one clamping arm against the machine housing, the latter spring / damping element is subjected to higher loads is. A particularly favorable and space-saving arrangement results when the clamping arms are arranged on a common bearing pin which is fastened to the machine housing.
- Two or more torsion springs can also be provided, which are supported individually on the machine housing and on each tensioning arm.
- each damping arm is also assigned a damping device with two damping elements, one damping element with a tension arm and the other damping element is fixed relative to the machine housing.
- the damping elements can be designed in a simple manner as a friction disk and friction lining, the friction lining preferably being connected in a rotationally fixed manner to the tensioning arm and the friction disk in a rotationally fixed manner with the bearing pin or with the machine housing.
- FIG. 1 shows a side view of two traction mechanism drives with a tensioning device
- FIG. 2 shows a side view corresponding to FIG. 1 with a modified clamping device
- 3 shows a side view of two traction mechanism drives according to FIG.
- FIG. 4 shows a section through a tensioning device according to FIG. 3,
- FIG. 5 shows a side view of two traction mechanism drives with a modified tensioning device
- FIG. 6 shows a side view of two traction mechanism drives with a tensioning device similar to FIG. 3, but in which the tensioning direction of the one tensioning roller is modified and
- FIG. 7 shows a side view of two traction mechanism drives with a tensioning device, the tensioning arms of which are independently biased and damped.
- 1 denotes a first traction drive, the drive pulley 2 of which is arranged on a crankshaft (KW).
- the driven pulley 3 of the first traction mechanism drive 1 is connected to a second drive pulley 4 of a second traction mechanism drive 5.
- a tensioning device generally designated 6, which has tensioning arms 7 and 8, at the ends of which tensioning rollers 9 and 10 are mounted, which are operatively connected to the first traction mechanism drive 1 and the second traction mechanism drive 5.
- the clamping arms 7 and 8 are arranged on a bearing pin 11 which is fastened to a machine housing 12 which is only indicated in FIG. 4.
- FIG. 7 shows spring / damping elements 13a, which are modified in such a way that each spring / damping element supports and dampens each clamping arm 7 and 8 individually with respect to the machine housing, which is not shown there.
- the tensioning arm 8 is supported on a machine housing (not shown) by means of a spring, while a further spring is provided between the tensioning arm 8 and the tensioning arm 7, which prestresses the tensioning arm 7 with respect to the tensioning arm 8.
- the bearing pin 11 has a head which represents an axial fixation with respect to the machine housing 12. It carries radial bearings 15 which support the clamping arms 7 and 8.
- a torsion spring 14 is provided between the tensioning arms 7 and 8, which prestresses the tensioning arms as shown in FIG. 3.
- the clamping arms 7 and 8 have on the surfaces facing away from one another in the area of the bearing pin 11 friction linings 16 which are in operative connection with friction disks 17.
- the friction disk 17 assigned to the tension arm 7 is supported in a rotationally fixed manner on the machine housing 12, while the friction disk 17 assigned to the tension arm 8 is connected in a rotationally fixed manner to the head of the bearing pin 11, the bearing pin 11 being fixed in a rotationally fixed manner on the machine housing 12.
- the tensioning device according to FIG. 6 essentially corresponds to the tensioning roller according to FIGS. 3 and 4. It differs from this tensioning device in that two torsion springs are provided support and on the other hand are each connected to a tension arm or that one torsion spring is supported on the machine housing and is connected to one tension arm, while the other torsion spring is supported on both tension arms.
