Definitions
- the present invention relates to a set of torsion springs, in particular for the drive train of a motor vehicle, with a first component located on the inside and a second component located on the outside rotatably therewith, with a spring acting between the first and second components, which is designed as a torsion spring, and with a first fastening arrangement for connecting a first end section of the spring to the first component and a second fastening arrangement for connecting a second end section of the spring to the second component, the spring extending essentially in the circumferential direction over at least part of the circumference of the first component.
- Torsion spring sets which, like the torsion spring set according to the present invention, can be used for the vibration-related decoupling of the drive train in motor vehicles are known.
- the background to the use of such torsion spring sets is that the internal combustion engines used in motor vehicles generate a torque on the crankshaft, the course of which is not constant over time.
- the middle torque of the engine is overlaid with dynamic components that lead to a non-uniform rotation of the crankshaft and the components connected to it. This creates vibrations in the drive train that can impair the driving comfort of the motor vehicle.
- An efficient way to reduce the transmission of the torsional vibrations from the crankshaft to the drive train is to decouple vibrations between the crankshaft and the drive train.
- a second rotating mass is usually connected to the flywheel of the crankshaft via a relatively soft torsion spring. While the flywheel follows the irregular rotation of the crankshaft, the speed fluctuations of the second rotating mass, which is connected to the gearbox via a clutch, are significantly smaller. In this way, the drive train can be calmed down.
- the central element of a torsion spring set is the torsion spring between the two rotating masses.
- the torsion spring must be flexible enough to adequately decouple the vibrations of the crankshaft; on the other hand, there must be sufficient spring travel to absorb the static torque of the engine and, in addition, to allow the relative movements between the two rotating masses caused by the crankshaft vibrations.
- torsion spring An example of a torsion spring is known from DE 40 06 121 A1.
- the spring is designed as a spiral spring which extends in several turns around the first inner component.
- the spring is accommodated in an installation space which is delimited by an outer contour and an inner contour.
- the outer contour and inner contour are concentric to the axis of rotation arranged.
- the disadvantage of the known arrangement is that it takes up a relatively large amount of space.
- the power density of the spring which in this context means the ratio of the torque that can be transmitted by the spring when maintaining a required stiffness to the installation space required by the spring, is not sufficient in all cases.
- the object of the present invention is therefore to provide a torsion spring set which takes up only a small amount of space.
- the object is achieved in the case of the torsion spring set with the features mentioned at the outset in that at least one of the fastening arrangements is designed such that the first and / or second end section is moved in the radial direction relative to the second component when the first component is rotated.
- a particularly simple design of the torsion spring is achieved in that one end section of the spring is firmly connected to the first or second component, while the other end section is arranged movably.
- the spring is accommodated in an installation space which is delimited by an outer contour and an inner contour, and that the maximum angle of rotation between the first is caused by the spring resting on the outer contour or inner contour and the second component is limited.
- the outer contour can be formed by the inner surface of the second component and the inner contour by the outer surface of the first component.
- the outer contour and inner contour are designed such that they limit deformation of the spring, which not only limits the angle of rotation between the first and second component, but also the mechanical stress on the spring body.
- the outer contour and / or the inner contour of the installation space are designed as an arc.
- the circular design means that when the spring, which in particular also extends over a circular arc and has a constant spring cross section, is applied to the outer contour or inner contour, a uniform deformation and stress is formed.
- a further improvement in the power density of the torsion spring set is achieved in that the outer contour and / or the inner contour are offset from one another.
- the outer contour and the inner contour are designed as arcs, the centers of the arcs are spaced apart from one another.
- the spring is compressed, the outer contour and the inner contour are rotated relative to one another about the common axis of rotation of the first and the second component.
- the center points of the arcs are in particular spaced from the axis of rotation.
- Inner contour when the spring is compressed until it rests on the inner contour on or adjacent to a straight line through the axis of rotation and a center of the firmly clamped end section.
- the focus is on this the inner contour in particular between the axis of rotation and the firmly clamped end section.
- the set of torsion springs can be designed according to the invention in such a way that the center point of the outer contour comes to lie on or adjacent to a straight line through the axis of rotation and the center of the firmly clamped end section when the spring springs out until it rests on the outer contour.
- the center point of the outer contour lies in particular on the section of the straight line which lies on the other side of the axis of rotation, on the side facing away from the firmly clamped end section.
- At least one of the fastening arrangements is designed such that the first and / or second end section is rotated about a pivot point when the first component is rotated relative to the second component. Twisting in this context means a rotation about a pivot point that is different from the axis of rotation. In this way, radial movement and rotational movement of the end portion of the spring is achieved. The stress on the spring in the region of the end section is thereby further reduced.
- At least one of the fastening arrangements has a spring-side first fastening section which interacts with a second fastening section of the first or second component.
- the first and second fastening sections can be positively connected to one another.
- the first fastening section is designed as a fastening foot having a tip and that the first and second fastening section are formed such that the fastening foot is rotated around its tip relative to the second component when the first component is rotated.
- a reliable fixing of the end section of the spring is achieved.
- due to the rotation of the fastening foot about its tip a radial displacement and a rotation of the end section of the spring can be achieved.
- the spring extends around the first component by an angle of less than 360 °.
- the single spring is not wound around the first component several times.
- the angle specification only refers to the effective spring length.
- a static imbalance of the torsion spring according to the invention can be avoided in that the torsion spring has at least one spring combination of a number n springs, the springs being parallel to one another and
- n is n greater than or equal to 2.
- each spring combination has two springs, a total of four springs are provided connected in parallel and arranged next to one another in the axial direction with respect to the axis of rotation.
- the two outer springs are arranged identically in their rotational position.
- the inner springs are both rotated by 180 ° about the axis of rotation compared to the outer springs.
- the spring combination arranged further to the left is mirror-symmetrical to that further to the right arranged spring combination, the plane of symmetry running in the middle between the two spring combinations.
- the inner springs are rotated 180 ° around the axis of rotation compared to the outer springs.
- the advantage of this arrangement is that the center of gravity of the spring assembly and the first and second component with inner contour and outer contour lies on the axis of rotation and thus a static and / or dynamic imbalance can be avoided when the parts rotate.
- This advantage can also be achieved in an analogous manner with other numbers of springs, for example by combining the two springs located inside in a single spring of double width. It is advantageous that the springs and the first and second components are arranged symmetrically with respect to a plane through the axis of rotation and the common center of gravity of all the springs comes to lie on the axis of rotation.
