The utility model relates to a self-controlling clutch for shafts intersecting at a 45 degree angle, including a drive shaft (1), ending with a fork (2) connected to a cross shaft (3) by hinges which are perpendicular to the axis of the shaft (1). The other two opposite ends of the cross shaft (3) are connected by control hinges (5, 6) to an intermediate control shaft (4) with two other hinges positioned symmetrically and perpendicularly to the control hinges (5, 6), to which, a second fork (7) is connected, with which an output shaft (8) ends. The three shafts (1, 4, 8) are connected to a control mechanism, which according to the utility model, consists of four symmetrically positioned springs (9), whereby two of the springs (9) are attached in one of their ends to the drive shaft (1), and, in their other ends, to the oppositely positioned control hinges (5, 6). The ends of the other two springs (9) are attached to the output shaft (8), and their other ends are attached to the oppositely positioned control hinges (5, 6), so that together with all shafts (1, 4, 8), they form a rotating group. The springs (9) can have the same stiffness and shock absorbers (10) can be mounted concentrically in them. The advantages of the clutch, according to the utility model, are the significantly increased reliability and lower cost, due to the use of a simple self-controlling system consisting of only four springs with the same stiffness, which reduces the overall maintenance costs throughout the useful life of the mechanism. |
