Definitions
- the invention relates to a damping device for a transmission arrangement with two transmission elements.
- the invention further relates to a transmission arrangement with at least two
- the invention also relates to a roll stabilizer with a gear arrangement and / or a damping device.
- the present invention is generally applicable to any gear assemblies and transmission elements, the present invention is with respect to a gear arrangement in the form of a gear arrangement with gears as
- Gears which run for example in a transmission and are in engagement with another gear, have a backlash, which in a
- a gear arrangement for a transmission comprising a first and a second gear half, which are limited by an elastic member about a central axis relative to each other rotatably connected to each other, wherein the elastic member on a respective inner peripheral surface of the respective gear half is arranged to move the two gear halves relative to each other angularly limited, wherein the elastic element is formed substantially hollow cylindrical.
- An object of the present invention is therefore to provide a damping device for a gear assembly, a gear assembly and a roll stabilizer, which is simple in construction, requires fewer components, and also easy and inexpensive to produce and provides improved damping, in particular a reduced clearance between two transmission elements.
- Another object of the present invention is to provide an alternative damping device, an alternative transmission arrangement, and an alternative roll stabilizer.
- the present invention solves the problems in a damping device for a transmission arrangement with two transmission elements in that a
- Torque transmission device is arranged for the transmission of
- Torque transmission device comprises a solid shaft, which is designed to provide a torsion spring effect upon rotation of the two gear elements relative to each other.
- the present invention solves the problems in a gear arrangement with at least two gear elements in that a damping device according to one of claims 1-4 is arranged.
- the present invention solves the problems with a roll stabilizer with a gear arrangement according to one of claims 5-9 and / or with a
- the two transmission elements are arranged coaxially with the solid shaft. This provides a simple and at the same time compact damping device.
- At least one transmission element is connected by means of a press fit and / or by means of a positive connection with the solid shaft.
- the two gear elements are designed as gears.
- the solid shaft of the damping device is arranged by means of at least one pivot bearing in a transmission element carrier. So that the solid shaft can be stored easily.
- the at least one pivot bearing in the form of a sliding bearing, in particular made of plastic or a rolling bearing, in particular of metal, is formed. If the pivot bearing is provided in the form of a plain bearing made of plastic, a light,
- pivot bearing in the form of a rolling bearing, a particularly reliable bearing is provided which can absorb high forces.
- a spacer element is arranged between one of the rotary bearing and a transmission element.
- the advantage of this is that so that loads can be avoided by the transmission element on the transmission element carrier.
- the transmission arrangement of the transmission element carrier in the form of a planet carrier of a planetary gear and the transmission elements in the form of planets of the planetary gear are formed. In this way, a particularly simple and reliable damping of the planet or planet gears of the planetary gear can be provided.
- FIG. 1 shows a gear arrangement according to an embodiment of the present invention
- FIG. 3 shows a roll stabilizer with a gear arrangement and a
- Figure 1 shows a transmission arrangement according to an embodiment of the present invention.
- FIG. 1 shows a transmission arrangement 2 with a damping arrangement 1.
- the gear assembly 2 comprises two planetary gears 3, 4 made of metal of a planetary gear, which are rotatably supported by a torsion spring 5 in the form of a metallic solid shaft.
- the solid shaft 5 is mounted on two pivot bearings 8 - in Fig. 1 left of the planetary gear 3 and the right of the planetary gear 4 - on a planet carrier made of metal 9 of the planetary gear.
- the pivot bearing 8 while firmly arranged in the planet carrier 9.
- the planetary gears 3, 4 are further rotatably connected via connections 6, 7, here in the form of a press connection with the solid shaft 5. Now learns the one planetary gear 3, a different torque than the planetary gear 4, this relative rotation of the two planetary gears 3, 4 is cushioned to one another via the solid shaft 5.
- FIG. 2 shows parts of the gear arrangement according to FIG. 1, viewed along the solid shaft.
- the planetary gear / the planet 3 or the planetary gear / the planet 4 are shown individually on the left or in the center.
- the arrangement of the two planet gears 3, 4 is shown in the unloaded state.
- the two planet gears 3, 4 are coaxial with each other on the solid shaft fifth arranged.
- the teeth 10, 11 of the two planet gears 3, 4 are slightly rotated in the unloaded state of the torsion spring or the solid shaft 5 shown here (reference numeral 12) as already mentioned above. This springing of the planetary gears 3, 4 is already in the assembly of the
- Gear assembly 2 and damper device 1 made.
- the two planetary gears 3, 4 each have a toothing 10, 11, which is aligned in each case defined to a hole with a contour shape, which in the second
- Planet 4 is arranged differently than the first planetary gear 3. Are the two planetary gears 3, 4 formed with the common solid shaft 5 as
- Torsion spring connected then deviates the orientation of the teeth 10, 11 from the left planetary gear 3 to the right planetary gear 4 from. If solid shaft 5 and planet gears 3, 4 are rotatably rotated during assembly, so that overlap the teeth 10, 11, a torsional moment by as
- Trained as a torsion spring shaft 5 can be joined with positive connection within the planet carrier 9.
- a press fit between the respective planet gear 3, 4 and trained as a torsion spring solid shaft 5 can be pre-assembled, in which case the sub-assembly by a larger
- Figure 3 shows a roll stabilizer with a gear assembly and a
- FIG. 3 shows a part of a known chassis of a motor vehicle.
- the area of a rear axle of a vehicle is shown.
- wheels 202 are connected via a rear axle 203 of the vehicle with a damper 200 and a strut 201.
- Strut 201 and damper 200 are in turn connected to a body 204 of the vehicle.
- the vehicle axle 203 is further connected to a stabilizer arrangement 30 in order to minimize rolling movements when turning the vehicle.
- the stabilizer assembly 30 includes an actuator 205, which includes an electric motor 40 and a transmission 50, with the two sections 30a, 30b of the stabilizer assembly 30 are rotated against each other to compensate for said rolling movements of the vehicle.
- the transmission 50 in this case comprises a damping device according to Figure 1, so that when the load changes the vehicle hitting the transmission 50 of
