Embodiment Construction

[0033] exist figure 1 A double flywheel shock absorber 1 according to a first embodiment of the invention is shown above, in particular for a transmission of a motor vehicle. The double flywheel shock absorber comprises a primary flywheel 2 and a secondary flywheel 3 , one movable in rotation about an axis X relative to the other.

[0034] The primary flywheel 2 comprises a central axle seat 4 called a primary axle seat comprising a cylindrical tubular portion 5 from which a radial portion 6 extends radially outwards. The radial portion 6 of the primary axle seat 4 is fixed by screws (not shown) to the end of the crankshaft of the internal combustion engine. The radial portion 6 is also fixed to the radially inner periphery of the primary inertial mass 7, which is annular and extends radially. According to a variant, the primary inertial mass 7 is fixed to the radial portion 6 by means of a flexible steel plate 8 , as is known to those skilled in the art. Such flexible stee...

Abstract

The invention relates to a torque-transmitting device (1) comprising a torque input member (2) and a torque output element (3) which are relatively movable in rotation, and elastic members (24, 25) coupled between the torque input member (2) and said torque output element (3) are mounted, wherein the torque input member (2) comprises a first part (7) and a second part (16, 19, 22), by torque-limiting means (14, 15 ) are rotationally connected to each other, and wherein the torque-limiting means are designed such that the first and second parts are combined and rotate when a torque transmitted to the first part (7) is smaller than a predetermined threshold value, and are designed to allow the first part (7) to rotate relative to the second part (16, 19, 22) when the torque transmitted to the first part (7) is greater than the threshold.

Description

technical field [0001] The invention relates to a torque transmission device, in particular for motor vehicles. In particular, the invention relates to a double flywheel shock absorber. Background technique [0002] The applicant's patent application DE 100 33 523 describes a double flywheel shock absorber comprising a primary flywheel and a secondary flywheel, one relative to the other, and radially acting elastic members. One is active in rotation, the elastic member is mounted between said flywheels. The double flywheel shock absorber also includes a torque limiting unit for the secondary flywheel. [0003] The primary flywheel is used to secure the end of the crankshaft of an internal combustion engine. The secondary flywheel is used to couple to the input shaft of the gearbox via a clutch. [0004] More particularly, the secondary flywheel includes a first radially inner portion, and a second radially outer portion for coupling to the input shaft of the gearbox. ...
