The invention relates to a vibration damping system for a motor vehicle transmission, comprising:

Pendulum damping system equipped with support member having raceways juxtaposed continuously around rotation axis

A torsion damping device () of an automotive temporary coupling system, comprising: a torque input element (A,B) and a torque output element (); an upstream circumferentially acting elastic member (A) capable of being loaded by or of loading the input element (A,B); a downstream circumferentially acting elastic member (B) capable of loading or of being loaded by the output element (); a radial phase washer (A,B) arranged so that the two elastic members (A,B) are mounted in series; each elastic member (A,B) is received circumferentially between a phasing face (A,B) and an oppositely located radial retention face (B,A) of the phase washer (A,B), the circumferential distance (D) between said faces (A,B,B,A) being equal at most to the circumferential length of the elastic member at rest.

Torsion damping device comprising elastic members held individually in position by phase washer

A torsion damping device (), in particular for a motor vehicle transmission, wherein the damping device () comprises at least two pendulum oscillators, a first washer (A) having at least one first pendulum oscillator (P) and a second washer (B) having at least one second pendulum oscillator (P).

A double flywheel vibration damper including two coaxial masses free to rotate relative to each other and acting against elastic parts, in which one of the masses, referred to as the first mass, is intended to be fastened to a drive shaft, whereas the other mass, referred to as the second mass, includes a reaction plate assuring rotational connection to a driven shaft, and in which the first mass has a central hub projecting axially and carrying bearing member operating between the second mass and the central hub to enable the second mass to rotate on the first mass, wherein the central hub comprises two aligned coaxial parts, namely a first hub supporting the second mass rotationally via the bearing member fitted on this first hub, and a second hub intended to be fastened to the drive shaft, and wherein the second hub constitutes an axial spacer between the drive shaft and the first hub. The invention is applicable to motor vehicle transmission systems.

A polarised manual gearchange lever for a motor vehicle gearbox or the like comprises an upstream part having a knob and carried by a downstream part of the lever, with a slight misalignment between the two parts occurring on manipulation of the knob, together with a force threshold detector which includes electrical sensor means. The force threshold detector comprises a resiliently deformable, or elastic, bar having a head portion, which is fixed with respect to the knob, and a foot portion which is fixed against deflection in a female element that is itself fixed to the downstream part of the lever.
