Abstract

The invention relates to a plate clutch (1) having a clutch housing (2) having a plurality of outer plates (3, 4, 5, 6) and inner plates (7, 8, 9) which are arranged in an alternating manner, wherein at least one weight (23, 24, 25, 26) is arranged on each outer plate (3, 4, 5, 6) and on each inner plate (7, 8, 9) for compensating a sum imbalance (17) resulting from individual imbalances (13, 14, 15, 16) of the plates (3, 4, 5, 6) which occur during operation of the plate clutch (1).

Description

Plate clutch with reduced imbalance
Technical Field
The invention relates to a plate clutch.
Background
Plate clutches have been known for a long time from the prior art. A plate clutch or friction plate clutch is a mechanical element. A typical characteristic of the clutch system compared to other clutch systems is that the inner and outer plates with friction linings are arranged in parallel. The same pressing force acts on all friction pairs.
The plate clutch is shiftable under load. They are often used because they are compact and inexpensive. In most cases, they operate in oil and are used primarily in an automatically controlled drive in high-load main or starting clutches or in locking differentials. In construction machines (Baumaschinen), the disk clutch is also used as a service brake and a parking brake.
In the prior art, it is disadvantageous that imbalances occur due to the fact that the outer plates are connected with play in the clutch housing, which imbalances can add up randomly in the case of a plurality of plates. According to the prior art today, the lamellae are designed rotationally symmetrically and take into account the resulting imbalance that occurs. In the double clutch, an imbalance of the respectively open clutch is added, wherein in this case the possible centering of the side (flankenzentrieng) is not effective due to the load freedom.
Disclosure of Invention
There is therefore a technical task to overcome the drawbacks from the prior art.
According to the invention, this object is achieved in particular by a multi-plate clutch having a clutch housing with a plurality of outer plates and inner plates arranged alternately, wherein at least one weight is arranged on each outer plate and on each inner plate, said at least one weight being used to compensate for a sum imbalance resulting from individual imbalances of the plates that occurs during operation of the multi-plate clutch.
By providing a specifically directed weight, the plate can be brought into a radially defined position such that individual imbalances of the individual plates are exactly compensated. Preferably, weight is understood as an additional mass.
The weight is preferably designed such that the imbalance caused by the additional mass is always greater than the tolerance-dependent imbalance caused by the tolerances of the clearances, masses and components in the system. In this way, a defined position of the unbalance with respect to each sheet can be achieved.
Preferably, the sum imbalance of the outer plates is compounded by individual imbalances in the outer plates in the shell in different radial directions. Preferably, the sum imbalance is understood to be a total imbalance. The weights are oriented in such a way that the sum imbalance is minimal. Particularly preferably, the individual imbalance of the slices results from the product of the offset of the slices and the mass of the slices. The mass of the sheet consists of the sheet's own weight and the weight placed on the sheet.
Preferably, the first outer sheet has a first weight, the second outer sheet has a second weight, the third outer sheet has a third weight, and so on.
Preferably, the first interior sheet has a first weight, the second interior sheet has a second weight, the third interior sheet has a third weight, and so on.
Preferably, the plate clutch is a multiple disc clutch. Preferably, the outer plate is a clutch plate, in particular a steel plate. Preferably, the inner plate is an output plate, in particular a friction plate.
It is particularly preferred that at least one recess or bore hole can be introduced into the sheet instead of the weight. By providing a specifically directed recess or bore, the plate can be brought into a radially defined position in such a way that individual imbalances of the individual plates are exactly compensated.
In one embodiment according to the invention, each outer plate has a region which projects into the housing opening of the clutch housing, wherein a weight is arranged on at least one of the regions.
This makes it possible to mount the weight on the outer sheet in a simple manner.
In a further embodiment according to the invention, the outer plates are arranged in the clutch housing in such a way that the weights are arranged radially offset from one another in the longitudinal direction of the multi-plate clutch.
In this way, the weight is oriented in the clutch housing such that the total sum imbalance is minimized.
In a further embodiment according to the invention, the weights are arranged radially offset from one another by an angle of 360 °/X, with the number of outer sheets X.
This illustrates the possibility of a structured arrangement of the weights on the outer sheet.
In another embodiment according to the invention, each flap has at least one region on which a weight is arranged.
The weight can thus be mounted simply on the inner sheet.
In a further embodiment according to the invention, the inner disks are arranged in the clutch housing in such a way that the weights are arranged radially offset from one another in the longitudinal direction of the multi-disk clutch.
In this way, consider an alternative: the weights are oriented such that the sum imbalance is minimized.
In another embodiment according to the invention, the weights are arranged radially offset from one another by an angle of 360 °/X, with the number of inner sheets X.
Thereby illustrating the possibility of arranging the weight structurally on the inner sheet.
In a further embodiment according to the invention, the weight is arranged or formed as a gravity rivet (Wuchtnieten) by means of a punching method.
The weight can thus be simply mounted on the plate.
In another embodiment according to the invention, the product of the factors [ mass of weight ] x [ distance of center of gravity of weight to axis of rotation (z) of the outer plates ] is greater than the sum of the addends [ static unbalance of outer plates ] + [ dynamic unbalance of outer plates ].
In this way, the weights are oriented such that the sum imbalance is minimal.
In a further embodiment according to the invention, the static imbalance is derived from the imbalance of the outer plates themselves, and the dynamic imbalance is derived from the product of the mass of the outer plates and the play present between the outer shell surface (mantelflache) of the outer plates and the inner shell surface of the clutch housing.

Detailed Description
Fig. 1 shows a schematic longitudinal section of a known plate clutch 50. The multi-plate clutch 50 has a clutch housing 2 with a plurality of outer plates 3, 4, 5, 6 and inner plates 7, 8, 9 arranged in an alternating manner. Here, four outer sheets 3, 4, 5, 6 and three inner sheets 7, 8, 9 are shown.
Since the outer plates 3, 4, 5, 6 are connected with play in the clutch housing 2, a sum imbalance 17 occurs, which can add up randomly in the case of a plurality of outer plates 3, 4, 5, 6, as shown in fig. 3, in which a possible play 19 is shown. The sum imbalance 17 is composed of individual imbalances of the outer sheets 3, 4, 5, 6. The outer plates 3, 4, 5, 6 are rotationally symmetrical.
The individual imbalances 13, 14, 15, 16 of the outer sheets 3, 4, 5, 6 result from the product of the offset 13, 14, 15, 16 of the outer sheets 3, 4, 5, 6 and the mass of the outer sheets 3, 4, 5, 6. The mass of the outer sheets 3, 4, 5, 6 corresponds to the own weight of the outer sheets 3, 4, 5, 6. The resulting sum imbalance 17 is taken into account. In the double clutch, an imbalance of the respectively open clutch is added, wherein in this case the possible side centering is not effective due to the load freedom.
Each outer plate 3, 4, 5, 6 has a region 11 which projects into a housing opening 10 of the clutch housing 2. The clutch housing prevents a displacement of the outer plates 3, 4, 5, 6 beyond the geometry of the clutch housing 2. The offset of the outer sheet 3 is shown in fig. 2.
Fig. 4 shows a schematic longitudinal section of a multi-plate clutch 1 according to the invention. The multi-plate clutch 1 has a clutch housing 2 with a plurality of outer plates 3, 4, 5, 6 and inner plates 7, 8, 9 arranged in an alternating manner. Here, four outer sheets 3, 4, 5, 6 and three inner sheets 7, 8, 9 are shown. On each outer sheet 3, 4, 5, 6 a weight 23, 24, 25, 26 is arranged. The first weight 23 is disposed on the first outer sheet 3, the second weight 24 is disposed on the second outer sheet 4, the third weight 25 is disposed on the third outer sheet 5, and the fourth weight 26 is disposed on the fourth outer sheet 6.
Each outer plate 3, 4, 5, 6 has a region 11 which projects into a housing opening 10 of the clutch housing 2. A weight 23, 24, 25, 26 is arranged on one of the regions 11 of each outer sheet 3, 4, 5, 6, respectively.
The outer plates 3, 4, 5, 6 are arranged in the clutch housing 2 in such a way that the weights 23, 24, 25, 26 are arranged radially offset from one another in the longitudinal direction z of the multi-plate clutch 1. The weights 23, 24, 25, 26 are each arranged radially offset by 90 ° from one another. The weights 23, 24, 25, 26 are oriented in such a way that the total imbalance 17 is minimized or compensated for.
The weights 23, 24, 25, 26 are arranged or formed as gravity rivets by means of a punching method.
The weights 23, 24, 25, 26 are used to compensate for the sum imbalance 17 which occurs when the multi-plate clutch 1 is in operation. According to fig. 6, the resulting total imbalance 17 is caused by the individual imbalances 13, 14, 15, 16 of the outer plates 3, 4, 5, 6 in the plate shell 2, wherein a possible gap 19 is shown. The product of the offset 13, 14, 15, 16 of the outer sheets 3, 4, 5, 6 and the mass of the outer sheets 3, 4, 5, 6 yields a single imbalance 13, 14, 15, 16 of the outer sheets 3, 4, 5, 6. The mass of the outer sheets 3, 4, 5, 6 consists of the own weight of the outer sheets 3, 4, 5, 6 and the weights 23, 24, 25, 26 arranged on the outer sheets 3, 4, 5, 6. The offset of the outer sheet 3 is shown in fig. 5. Since the individual imbalances 13, 14, 15, 16 of the outer sheets 3, 4, 5, 6 are all oriented in opposite directions, a compensated sum imbalance 17 results, which is equal to zero.
Fig. 7 shows a further schematic cross section B-B of a subregion of the multi-plate clutch 1 from fig. 4.
As already mentioned, the weights are oriented such that the sum imbalance is minimal. The weights are arranged such that the imbalance due to the additional mass is always greater than the tolerance-dependent imbalance due to the tolerances of the gaps, masses and components in the system. In this way a defined position of the unbalance with respect to each slice is achieved.
The product of the factors [ mass of the weight 23 ] x [ distance 20 from the center of gravity of the weight 23 to the axis of rotation z of the outer plate 3 ] is greater than the sum of the addends [ static imbalance of the outer plate 3 ] + [ dynamic imbalance of the outer plate 3 ].
The dynamic imbalance results from the product of the mass of the outer plates 3 and the gap 19 which exists between the outer lateral surface of the outer plates 3 and the inner lateral surface of the clutch housing 2.
