Embodiment Construction

[0026] figure 1 By way of example, a torsional vibration damper 1 in the form of a dual-mass flywheel is shown, which has a primary part 2 and a secondary part 3 , which can be joined together about an axis of rotation 4 . Rotation and limited twist relative to each other. A spring damper arrangement 5 with a mechanical accumulator in the form of an arc spring 6 acts between the primary part 2 and the secondary part 3 . A torsional vibration damper 1 for a powertrain of a motor vehicle operating with an internal combustion engine, in particular for a DHT hybrid application, has the task of damping rotational inhomogeneities in the powertrain caused by the internal combustion engine.

[0027] The primary part 2 comprises a flange element 7 , which is connected radially outside in one piece to the primary cover 8 , which together enclose a spring space 9 which defines a spring space 9 for accommodating the arc spring 6 . In this case, the arc spring 6 is supported by one sprin...

Abstract

The invention relates to a torsional vibration damper (1), which is designed as a dual mass flywheel and comprises a primary part (2) and a secondary part (3), which are arranged together so as to be rotatable about an axis of rotation (4) and so as to be rotatable relative to one another, the primary part and the secondary part are arranged in the torque flow, and a spring damper device (5) is arranged between the primary part and the secondary part, the multi-part secondary part (3) comprises a torque limiter (12) which is designed as a slip clutch, the carrier flange (10) and the driving disc (16) of the secondary part are connected via at least one friction lining (17, 18), and the friction lining (17, 18) is arranged between the primary part and the secondary part. Wherein the drive disc (16) is coupled to the driven hub (11) and the centrifugal pendulum device (24), and the primary part (2) is screwed on the crankshaft of the internal combustion engine by means of a screw (29) which can be inserted into a bore (30) of the primary part (2) through an opening (36) of at least one component of the secondary part (3). The output hub (11) is guided axially on a support disc (15) associated with the carrier flange (10) and is connected in a form-fitting manner to the drive disc (16) via an engagement (31), the engagement (31) being releasable by an axial displacement of the output hub (11) against a spring force of at least one compression spring (34) and then the output hub (11) being rotatable, the opening (36) in the driven hub (11) and the hole (30) of the primary part (2) are aligned in position.

Description

technical field [0001] The invention relates to a torsional vibration damper, which is designed as a dual-mass flywheel and comprises a primary part and a secondary part, which together are rotatable about an axis of rotation and are opposite each other are arranged so as to be twistable relative to each other, and a spring damper arrangement is arranged in the torque flow between the primary part and the secondary part, wherein the multi-part secondary part comprises a torque limiter formed as a slip clutch, and the carrier flange of the secondary part and the slaving disc are connected via at least one friction lining, and the slaving disc is coupled to the driven hub and the centrifugal pendulum, and the primary part is fastened by means of screws at the crankshaft of the internal combustion engine, The screw can be inserted into the bore of the primary part through an opening of at least one component of the secondary part. Background technique [0002] In a motor vehic...
