Abstract: A limited slip differential comprising an input member and two output members and moreover having, built into a housing, at least one planet gear and at least one sun gear that are arranged so as to enable total or partial securing, rotatably, of two of the three input and/or output members by means of at least one thrust means on a securing means during a decrease in one of the output torques caused by grip loss or shifting into differential velocities. The differential also includes at least one second dynamic thrust means that is antagonistic to the thrust of the first thrust means, the antagonistic second dynamic thrust means being arranged so as to be activated during a shift of the differential into differential velocities.

Abstract: This invention relates to a device for correcting the alignment of the machining of a chainset housing (1b), the housing comprising a pair of half-casings (2a, 2b) inserted in one of the openings of the housing (1b) to position the parts (3a, 3b) of a pedalling effort or chain tension sensor which pivots inside the casing (2) and positions the shaft of the chainset (4) so as to rotate eccentrically compared to the pivot axis (Y-Y?) of the sensor (3) inside the casing (2), said device being characterized in that the sensor enables pivoting of the half-casings via a rolling-contact bearing (5) which, in a cross section passing through the axes of the half-casings, allows a ball-joint-like turning of the pivot axis of the effort sensor (3) with respect to the axes of the half-casings in order to allow the pivot axis of the sensor to be positioned independently of the axes of the two half-casings so that errors of alignment between the axes of the two half-casings can be eliminated.

Abstract: A compensation device for a shock absorber comprising a hydraulic volume formed by two chambers separated by a removable wall of a piston and including at least one cartridge defining a shock-absorber body and a rod attached to the mobile wall of the piston. The hydraulic shock absorber includes an outer tube defining a cartridge in which said shock body is provided. The inner wall of the outer tube being capable of sliding against the outer wall of the shock absorber body so as to compensate, at the hydraulic chamber in which the piston rod is inserted, for the volume of the portion of the piston rod inserted into the hydraulic chamber upon a compression phase.

Abstract: The invention relates to a device for controlling a suspension hydraulic shock-absorbing device (2, 5) mounted on the frame (11) of a cycling vehicle, characterised in that the mobile wall of the piston (18) is provided with a valve, the opening of which is controlled by a cycling or tension detector (13) and controls the fluid flow from a chamber of the hydraulic portion to another one, and in that the valve is actuated by an actuation device attached to a cable (6) of the detector (13), the actuation device pivoting between a first valve-opening position and a second valve-closing position, the cable exiting its sheath at the level of a holder (43), wherein a compression spring (41) is positioned between the holder and the position for attaching the cable to the actuation device in order to resist the traction force of the cable on the actuation device, and returns the actuation device into a valve-opening position.

Abstract: A sensor for pedalling force and/or chain tension is mounted on a bicycle frame bottom bracket axle. An intermediate element that can pivot relative to the bottom bracket axle can pivot relative to the frame about a ring offset relative to the bottom bracket axle. A deformable retainer counters pivoting of the element. The element signals a stiffness controller with an indication of pedaling force and/or chain tension in response to the element being rotated in opposition to the holder.

Abstract: A device for actuating a system such as a clutch or a gearbox associated with an engine, particularly a motor vehicle engine, and comprising control element (26-31) and an actuation member (38). According to the invention, the device furthermore includes:a first shaft (4) rotationally driven by the engine;a second shaft (6) integral with the actuation member;coupling member (10, 13, 15, 16, 33) for coupling the second shaft to the first shaft under the action of the control element;a member (16, 32, 33; 48, 53) for uncoupling the second shaft from the first shaft after the second shaft has rotated through a predetermined angle; anda return spring (35) for returning the second shaft to its initial position after it has been uncoupled from the first shaft.

Abstract: This device comprises levers and cables (21, 29, 23) for actuating a clutch which is located between an engine and the gearbox, spring (37) for determining the angle through which the engine is rocked with respect to a nominal operating position, and cable (39) for opposing clutch engagement when the angle of rocking is greater than a predetermined angle.
