Problems solved by technology

[0004] However, these devices have the disadvantage that a considerable amount of pressing force has to be stored, because a purely mechanical pressing device can hardly react to changing overall operating parameters, or because a pressing device controlled from the outside requires a relatively long reaction time

Embodiment Construction

[0077] figure 1 The transmission mechanism of the invention comprises an input cone 1 and an output cone 2, which interact with each other via an adjustable friction ring 3 in a manner known per se. In this case, the input cone 1 is operatively connected to the drive shaft 4 and the output cone 2 is operatively connected to the output shaft 5 . In the exemplary embodiment, the cones 1 , 2 are supported radially via cylindrical roller bearings 6 . Furthermore, the cones 1, 2 are axially clamped relative to each other in this embodiment via a four-point bearing 7A, so that the required clamping force can be applied, whereby the torque is transferred from the input cone via the friction ring 3 1 to output cone 2 or vice versa. The axial support of the input cone 1 is not shown in detail in this figure, but can likewise be realized, for example, by a four-point bearing roller bearing 7A or by an axial cylindrical roller bearing or the like.

Abstract

The invention relates to a cone-friction gear and method for making the cone-friction gear operate. The cone-friction gear comprises at least one input piece and at least one output piece which mutually relatively compact each other in aid of a compacting device, characterized in that: the compacting device operates by one operation state-compact force-characteristic curve and the average gradient of the operation state-compact force-characteristic curve between the static state of the cone-friction gear and the first operation state is different from the average gradient between the first operation state and the second operation state; at least one compact unit is operated by the operation state-compact force-characteristic curve of basically constant gradient.

Description

[0001] The application for the present invention is that the original application number is 03801159.X, the application date is December 23, 2003, and the title of the invention is "a pressing device for clamping two transmission parts and a transmission mechanism with this pressing device and the operation of this A divisional application of the patent application for a method for a friction transmission mechanism. technical field [0002] The invention relates to a conical friction drive and a method for operating the conical friction drive. Background technique [0003] Such a pressing device or a transmission is known, for example, from EP 0 878 641 A1 or EP 0 980 993 A2. In their second embodiment, the two documents disclose a pressing device, which applies a pressing force according to the transmitted torque of the driven cone of the disclosed conical friction ring transmission mechanism, and uses this pressing force to push the two The cone and the friction ring betw...
