Embodiment Construction
[0037] Figure 1a to Figure 1c Different embodiments of a compensating device for reducing vibrations in a traction drive are shown in plan view from the front. One or two balance masses 2 are respectively movably arranged on the mass support body 1 of the balance device and each balance mass 2 is equipped with an adjustment mechanism 3 , which adjusts the balance mass 2 in the direction of rotation D of the shaft 4 On or against the direction of rotation D of the shaft 4.
[0038] exist Figure 1aIn the balancing device shown, only one balancing mass 2 is arranged on the mass support body 1 at a distance from the axis of rotation A of the driven shaft 4 . The balancing mass 2 is moved by means of the adjustment mechanism 3 , which is supported on the mass support body 1 , preferably on a circular arc of the center of gravity of the balancing mass 2 about the axis of rotation A along or against the direction of rotation of the shaft. In addition to the desired compensating m...

The invention relates to a traction drive with a balancing device for reducing vibrations of a driven shaft (4) such as a camshaft of an internal combustion engine, a water pump shaft or a jet pump shaft, the traction drive having a shaft coupled A connected transmission wheel (9), transmission means, and at least one balancing mass (2) relatively movable in the traction transmission, and at least one adjustment mechanism (3) for moving the balancing mass. In this case, the balancing mass is movable in or against the direction of rotation of the shaft and the adjustment mechanism is designed as a tangentially acting actuator to move the balancing mass. Furthermore, the invention relates to a method for reducing vibrations in a traction drive with a driven shaft, a drive wheel and a transmission element, wherein at least one adjustment mechanism makes it possible for relatively movable At least one balancing mass is moved with the steps of: actuating the adjustment mechanism; moving the balancing mass; and generating a compensating moment at the driven shaft. In a control gear with a camshaft adjustment system for angular adjustment of the timing, the camshaft, which is movable relative to the traction gear, can simultaneously be used as a balancing mass for reducing vibrations.
Description
technical field [0001] The invention relates to a traction drive (Zugmitteltrieb), in particular for an internal combustion engine, with a balancing device for reducing vibrations in the traction drive, the traction drive having a driven shaft, a Transmission wheels, transmission means, at least one balancing mass relatively movable in or against the direction of rotation of a shaft in a traction drive, and at least one adjustment mechanism for moving the at least one balancing mass (Stellmechanismus ). Furthermore, the invention relates to the use of a camshaft adjustment system (Nockenwellen-Verstellsystems) for reducing vibrations in a traction drive and a corresponding method for reducing vibrations in a traction drive. Background technique [0002] In the development of modern motor vehicles, so-called NVH behavior (noise, vibration, harshness) is becoming increasingly important. In addition to the buyer's desire to have a high level of vibration comfort, a lower nois...
