Problems solved by technology

[0006] In this type of torsional vibration damper, sliding sealing rings are used as seals, which has the disadvantage that fluids, especially silicone oil, are used as damping medium and do not have lubricating properties, making sliding sealings only limitedly suitable Solve sealing problems because the sliding seals have high wear over a short service life
Furthermore, sliding seals do not ensure complete protection against the intrusion of very small particles and, for example, water

Embodiment Construction

[0022] exist figure 1 and figure 2 The torsional vibration damper shown in and generally designated by the reference numeral 1 has a hub part 2 which can be fixed on the engine drive shaft and a flywheel ring 3 which surrounds said hub part 2 in the radially outer region, so The hub part may also be referred to as primary mass and the flywheel ring may also be referred to as secondary mass.

[0023] Between the hub part 2 and the flywheel ring 3 there is a gap 4 which is filled with a fluid, preferably silicone oil. The area of ​​the gap 4 is sealed outwards by a sealing means 5 which will be described in more detail below.

[0024] Each sealing device 5 comprises, respectively: a first ring 6 sealingly connected to the hub part 2; a second ring 7 also sealingly connected to the freewheel ring 3; and a ring 8 made of elastomer, which On the one hand, it is tightly connected to the first ring 6 and on the other side to the second ring 7 .

[0025] The respective first and ...

Abstract

A torsional vibration damper (1) having a hub part (2) (primary mass) which can be fastened on a drive shaft of a motor, and a flywheel ring (3) (secondary mass) which encloses the hub part (2) in theradially outer region, a gap (4) which is filled with fluid and a seal device (5) being provided between the hub part (2) and the flywheel ring (3), by means of which seal device (5) the escape of the fluid is to be avoided, is configured in such a way that the seal devices (5) in each case have a first ring (6) which is connected tightly to the hub part (2) and a second ring (7) which is connected tightly to the flywheel ring (3), and a ring (8) which is made from an elastomer and is connected on one side sealingly to the first ring (6) and on the other side to the second ring (7).

Description

technical field [0001] The invention relates to a torsional vibration damper with a hub part (primary mass) that can be fastened on the drive shaft of an engine and a flywheel ring (secondary mass) surrounding the hub part in a radially outer region. quality), wherein a fluid-filled gap and a seal are provided between the hub part and the flywheel ring, by means of which the fluid is to be prevented from escaping. Background technique [0002] A torsional vibration damper of this type is known, for example, from GB 11 05 292 A. [0003] This generally also refers to torsional vibration dampers with an outwardly offset flywheel ring, in contrast to which designs are also known in which the flywheel ring is mounted in a completely encapsulated manner in a separate housing. [0004] The disadvantage of the latter design is that the mass of the housing is not relevant for the function of the shock absorber and the heat dissipation is limited due to the encapsulation of the flyw...
