Embodiment Construction

[0026] Figures 1 to 11 The upper parts of the single-mass flywheels 100 , 200 , 300 , 400 , 500 , 600 , 700 , 800 , 900 , 1000 , 1100 , which are rotatable about the axis of rotation d, are respectively shown in section. Their distinction is derived from the individual views, where, Figures 1 to 11 The disclosure includes combinations and substitutions of features of the individual single mass flywheels 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100 with each other.

[0027] figure 1 A single mass flywheel 100 is shown with a disc 101 and a centrifugal pendulum 102 . The disc 101 comprises radially on the inside a fastening flange 103 with a reinforcement ring 104 which is connected to the crankshaft flange of the crankshaft of the internal combustion engine (not shown) by means of fastening openings 106 and screws 107 arranged on the pitch circle 105 superior. In this case, the contact surface 108 formed on the plane E1 bears against the end face of the clutch f...

Abstract

The invention relates to a single-mass flywheel (100). The single-mass flywheel (100) is provided with a disc part (101), mounting openings (106) radially inwards for attachment to a crankshaft of an internal combustion engine and arranged on a partial circle (105), a friction surface (114) on one side of the disk part (101), and an attachment means (119) for forming a friction clutch. To fully design a single-mass flywheel (100) with a low mass, being environmentally friendly, having low space requirement and being able to interpret adequately for vibration damping, a centrifugal pendulum (102) is disposed on the side opposite to the friction surface (114), wherein the axially extended mounting space, relative to the disk part (101), intersects with a plane (E1) of an axial abutment surface (108) of the mounting openings (106).

Description

technical field [0001] The invention relates to a single-mass flywheel with a disk and fastening openings arranged on a reference circle (Teilkreis) on the radially inner side for fastening on the crankshaft of an internal combustion engine, with a ring on one side of the disk friction surfaces and fixtures for the construction of friction clutches. Background technique [0002] Flywheels or single-mass flywheels in the sense of the present disclosure differ from dual-mass flywheels which directly receive the clutch pressure plate—as known for example from DE 10 2011 104 240 A1—for forming friction clutches and connecting them to the crankshaft of an internal combustion engine. In this case, the flywheel mass of the single-mass flywheel is used for vibration isolation of the rotational vibrations of the internal combustion engine in addition to the torsional damper, which may be integrated in the clutch disk. In order to achieve a corresponding degree of isolation, correspo...
