Embodiment Construction

[0096] exist figure 1 A torque transmission device is shown in , which here is a double flywheel damper 1 .

[0097] The dual flywheel damper 1 is integrated into the vehicle power train. The powertrain also includes heat engines with two, three, four, five, six, seven or eight cylinders.

[0098] In known manner, the double flywheel damper 1 comprises a primary flywheel 3 . The primary flywheel 3 comprises a flange to which the starter ring is attached. The flange and the starter ring are joined to each other at their radially outer peripheries so as to at least partially delimit the inner volume 5 . An elastic return member 9 , for example curved, such as a helical spring, can be mounted in said inner volume 5 .

[0099]The elastic return member 9 extends in the circumferential direction and bears at a first end on a flange and / or starter ring and at a second end on a flange 23 belonging to the secondary flywheel 6 .

[0100] The elastic return member 9 makes it possibl...

Abstract

The invention discloses a torque transmission device (1), and the device comprises a pendulum damping device (22), the device comprises a support member (24) capable of rotating and moving around an axis (X) and at least one swing body (25). The displacement of the pivoting body (25) relative to the support is guided by at least one rolling member (34), and a counter-bearing element different fromthe pendulum damping device, and a stop damping system (50) coupled to the support (24), wherein a stop position of the pivoting body (25) against the support (24) is allowed to be damped, the invention is characterized in that the stop damping system (50) can be deformed between a non-active position, in which the at least one pivoting body (25) reaches a stop position, and an active position, in which the stop damping system (50) is at least partially compressed against the counter-bearing element.

Description

technical field [0001] The invention relates to a torque transmission device with a pendulum damper, in particular a double flywheel damper. The torque transmitting device is integrated, for example, into a drive train of a motor vehicle. Background technique [0002] Traditionally, such pendulum dampers use a support and one or more oscillating bodies movable relative to the support, the displacement of each oscillating body relative to the support being guided by one or two rolling members, Said one or two rolling members cooperate on the one hand with a rolling track associated with the support and, on the other hand, with a rolling track associated with the oscillating body. Each oscillating body comprises, for example, two oscillating masses riveted to one another. [0003] From application DE 10 2014 208 126 a double flywheel damper comprising a pendulum damper is known. In order to damp the stop position arrival (la venue en position de butée) of the oscillating bo...
