Definitions
- the invention relates to a centrifugal pendulum device with the features according to the preamble of claim 1.
- centrifugal pendulum devices are known, for example as a torsional vibration damper in their mode of action in particular from the use in drive trains of motor vehicles, for example from DE 10 2004 011 830 A1.
- pendulum masses are arranged limited pivotally mounted on a pendulum, which is driven by a subject with torsional vibrations drive unit such as internal combustion engine.
- torsional vibrations drive unit such as internal combustion engine.
- the pendulum flange can for example be formed integrally from a component of a torsional vibration damper or a dual mass flywheel or be arranged on one of these components.
- Pendulum masses can be arranged on both sides of the pendulum flange, with axially opposite pendulum masses being connected to one another by means of bolts.
- the bolts move in this case in openings which are adapted to the shape of the pendulum movement of the pendulum masses.
- the guide of the pendulum masses on the pendulum by means of introduced into this cutouts which are complementary to cutouts formed in the pendulum, wherein rolling in the cutouts rolling elements.
- During operation of the centrifugal pendulum device may cause a collision of the pendulum masses with rotating pendulum. Also, in the transition from turning to stationary pendulum a jerky collision of a pendulum against the circumferentially adjacent pendulum mass is possible, which can lead to disturbing noises of the centrifugal pendulum device
- the object of the invention is to improve the noise comfort of a centrifugal pendulum device at the same time optimal space utilization, in particular to dampen a jerky interaction circumferentially adjacent pendulum masses or to avoid.
- centrifugal pendulum device with the features of claim 1. Accordingly, a centrifugal pendulum device with a pendulum and fasten with both sides of the pendulum by means of bolts and guided by rollers and limited to the pendulum limited pivoting pendulum masses proposed, at least two pendulum masses are circumferentially adjacent to the pendulum and each pendulum mass has a side surface of the adjacent pendulum mass facing and the contour of the side surface has a substantially acute angle.
- the contour of the side surface can be configured such that two adjacent pendulum masses with respect to the pendulum can perform as far as possible pendulum movement during operation of the centrifugal pendulum device during this do not touch the pendulum masses.
- the contours of two mutually facing side surfaces of adjacent pendulum masses each have an acute angle.
- the contour of the side surface of a pendulum mass with respect to the contour of the adjacent side surface of the adjacent pendulum mass with respect to a radially extending line is designed mirror-symmetrically.
- the tip of the contour may be rounded if two adjacent pendulum masses should touch the tip first under certain circumstances. However, the contour may be such that tip-to-tip impact is unlikely.
- two side surfaces of a pendulum mass are connected radially outside by an outside surface and radially inside by an inside surface, whereby the acute angle of the contour of the side surface between the outside surface or the inside surface and the side surface is enclosed.
- two side surfaces of a pendulum mass are connected radially outside by an outer surface and radially inwardly by an inner surface, wherein the acute angle of the contour of the side surface is formed within the side surface.
- the acute angle of the contour of the side surface is formed substantially radially centrally on the side surface.
- the two side surfaces of a pendulum mass each have an acute angle in the contour, wherein a contour relative to the other contour with respect to a radially extending line is designed mirror-symmetrical.
- the one contour with respect to the other contour of a common pendulum mass with respect to a radially extending line can be designed asymmetrically.
- Figure 1 Side view of a arranged on a component of a torsional vibration damper centrifugal pendulum device in a specific embodiment of the invention
- FIG. 2 Spatial detail view of detail A from FIG. 1.
- FIG. 1 shows a side view of a component of a torsional vibration damper 10.
- This component is designed here as a damper flange, which has in a radially inner region window cutouts 12 for receiving energy storage elements such as coil springs.
- the damper flange also forms the pendulum flange 22 of the centrifugal pendulum device 20, wherein in each case two pendulum masses 24 are arranged axially on both sides of the pendulum flange 22 and are connected to each other via bolts 26 to a pendulum mass pair.
- the bolts 26 engage through cutouts 28 in the pendulum flange 22, wherein the cutouts 28 are formed such that they allow a pendulum movement of the pendulum masses 24 relative to the pendulum flange 22.
- the pendulum masses 24 are guided over rolling elements 30 relative to the pendulum flange 22, for which purpose the rolling elements 30 can roll in cutouts 32 on the pendulum masses 24 and in complementary cutouts 34 on the pendulum flange 22.
- a pendulum mass 24 radially outside an outer surface 36 and radially inside an inner surface 38.
- this is limited by side surfaces 40.
- two side surfaces 40 of a pendulum mass 24 and a pendulum mass adjacent thereto are assigned to one another in each case. Wundt.
- the contour of the side surface 40 has an acute angle 42 substantially centrally with respect to the radial extension of the side surface 40, as well as the respectively adjacent side surface of the adjacent pendulum mass.
- the contours of the side surfaces respectively adjacent pendulum masses and the contours of the two side surfaces of a pendulum mass are designed mirror-symmetrically with respect to a radial line.
- the two mutually facing side surfaces 20 may have a certain fixed or changing distance to each other during operation of the centrifugal pendulum device, it may happen under certain circumstances that touch the two pendulum masses with their side surfaces. Due to the special, pointed configuration of the contour of the side surface, a jerky encounter of the pendulum masses can be reduced because the pendulum masses can slide past in sections by acting as a guide contour of the pendulum mass.
