Embodiment Construction

[0079] Identical or functionally equivalent elements are marked with the same reference symbols in all figures, so that different views of the device shown in the figures can also be understood from this. In particular, with the same reference numerals Figure 2A , 2B , 3A and 3B components correspond to Figure 1A with 1B parts and not specifically stated. Bolts 1a-1e correspond to Figure 1A with 1B the bolt 1.

[0080] Figure 2A with 2B A first design 200 of the invention is shown.

[0081] device 200 with the Figure 1A with 1B The arrangement 100 shown in FIG. 2 differs essentially in that two structurally identical additional elements 30 each in the form of a plate with an L-shaped cross section are fastened to the clutch housing 10 and to the flywheel housing 20 . In this case, the plate 30 is fastened on the clutch housing 10 in a friction fit with the pretension of the screws 1 a , 1 b and 1 c . Here, the plate 30 is composed of a flat, rectangular first sec...

Abstract

The invention relates to a friction fit connection and a method for increasing torque and / or lateral force. A device for friction-fitting, torque-transmitting and / or transverse-force coupling of two machine elements comprises a first machine element, a second machine element and at least one first fastening element, with which a preload can be generated, the preload The clamping force presses opposing separating surfaces of the first machine element and the second machine element, which are designed as friction surfaces, against each other in order to transmit a torque. In order to increase the torque and / or transverse force that can be transmitted via such an existing friction fit connection, at least one additional element is provided, which is fixed on the first component and on the second component. In this case, the fastening of the at least one additional element on the first component takes place in a friction fit using the pretension of the at least one first fastening element.

Description

technical field [0001] The invention relates to a device for friction-fitting, torque-transmitting and / or transverse-force-transmitting connection of two machine elements. Furthermore, the invention relates to a method for increasing the transmissible torque and / or the transmissible torque and / or the transmissible transverse force of a friction-fit connection of two machine elements via a friction-fit connection. Background technique [0002] Various connections of machine elements are known from the prior art, which have the task of transmitting torque or lateral force loads. In addition to form-fitting connections, friction-fitting connections are often used in machine construction. The transmissible torsional moment depends here on the diameter D of the friction surface, its distance from the axis of rotation or torsion and the normal force F acting there N And the friction value μ at this site. [0003] It is known from practice that in existing constructions it is on...
