摘要:
A transmission device for an automotive vehicle of the type includes, mounted on an output shaft formed by at least two wheel drive half-shafts of a vehicle mounted to freely rotate one relative to the other, at least one rotary gearwheel, and two clutch mechanisms with clutch sleeves arranged on both sides of the gearwheel. This device includes, on the one hand, two clutch sleeve configurations: the driving configuration of the gearwheel, and the engine brake configuration of the gearwheel, and, on the other hand, a declutching control mechanism that includes at least one clutch sleeve pilot unit, coaxial to the gearwheel, mounted relative to the gearwheel that moves angularly between two end positions. The declutching pilot unit can be driven into each of the end positions by the two wheel drive half-shafts when they are driven at a speed of rotation that is different from that of the gearwheel.

A reinforced vehicle structure includes a vehicle floor, a reinforcement member, an accessory attachment member and a plurality of mounting structures. The vehicle floor has an underbody floor surface facing an underbody of the vehicle and an interior floor surface facing an interior of the vehicle. The reinforcement member is mounted to the underbody floor surface. The accessory attachment member is mounted to the interior floor surface. The plurality of mounting structures is spaced along the reinforcement member and extends through the vehicle floor to couple the accessory attachment member to the reinforcement member.

A device for braking an elongated rotating body, includes at least two parts with coaxial conical surfaces, able to be slipped onto the body, and one, a so-called male cone, mounted integrally in rotation with the body, and the other, a so-called female cone, mounted fixed in rotation relative to the body. The female cone assumes the shape of a wheel with an axial bore with a conical bearing, and the male cone has a center recess. The cones are controlled in terms of axial relative movement by a control element. The male cone is, when the cones are close to one another, corresponding to the braking position, housed inside the axial bore of the female cone, with its conical external peripheral surface being held, by contact with a support, with the conical bearing of the female cone.

Transmission device between an input drive shaft and an output shaft, of the type including a housing inside which are placed at least partially a reduction gear mechanism and a progressive cone clutch mechanism, the reduction gear mechanism including a driving member engaged with a driven member, formed by a gearwheel mounted so as to rotate freely on the output shaft and able to be coupled to/uncoupled from the output shaft via two friction cones of the clutch mechanism, the cones being placed coaxial to the axial bore of the gearwheel and capable of coming, under the action of a control device, into bearing contact with a conical bearing surface of the gearwheel. The conical bearing surfaces of the gearwheel are, relative to the axis of rotation of the gearwheel, offset axially from the gear teeth of the gearwheel and are placed on the same side of the gear teeth.

A direction-reversing device includes at least one input shaft, an output shaft, and direction-reversing element with a clutch sleeve including a moving clutch sleeve, mounted to move axially on one of the shafts carrying it to enable occupying forward and reverse positions. This device also includes a blocking element that is driven in rotation by the input shaft that carries the moving clutch sleeve, whereby this blocking element is mounted to move between the off position, in which the moving clutch sleeve is able to switch from one operating position to the next, and the on position, in which the blocking element forms an obstacle that prevents the switching of the moving clutch sleeve from one position to the next, being able to switch automatically from the off position to the on position when the input shaft is driven at a speed of rotation that exceeds a predetermined threshold value.

A reinforced vehicle structure includes a vehicle panel, an elongated structural support member, and a support structure. The vehicle panel includes a first panel surface and a second panel surface, and defines a first opening that extends through the vehicle panel between the first and second panel surfaces. The elongated structural support member supports a portion of the first panel surface of the vehicle panel, and defines a first channel extending along the vehicle panel. The support structure is coupled to the structural support member at least partially within the first channel, includes a mounting structure that is aligned with the first opening in the vehicle panel, and defines a second channel extending transversely to the first channel of the structural support member.

A reinforced vehicle structure includes a first vehicle wall, a second vehicle wall, an accessory attachment member and a reinforcement member. The first vehicle wall has a first outer wall surface facing an outboard direction and a first inner wall surface facing an inboard direction. The second vehicle wall extends transverse to the first vehicle wall, and has a second outer wall surface facing a first direction and a second inner wall surface facing an opposite direction. The accessory attachment member is mounted to the first inner wall surface. The reinforcement member has a first end mounted to the accessory attachment member and a second end mounted to the second inner wall surface with the reinforcement member spanning the first and second vehicle walls such that the reinforcement member does not extend parallel to either of the first and second vehicle walls.

Transmission mechanism housing (1) of the type including two half-shells (1A, 1B) that can be assembled generally via a parting line, this housing (1) accommodating at least one control member (2) moved angularly with the aid of a lever (3) outside the housing (1), the lever (3) including a sleeve (4) that can be inserted removably into a receiving bearing (5) of the housing (1), the sleeve (4) being capable, in the state in which it is inserted into the receiving bearing (5), of being held in at least one predetermined axial position by locking elements (6A, 6B). The locking elements (6A, 6B) are configured in order to travel from the locked position to the unlocked position, and vice versa, by simple relative rotary movement of the sleeve (4) and of the bearing (5) about the longitudinal axis of the sleeve (4).

Transmission device for self-propelled equipment, includes a housing having a driving input shaft transmitting movement to an output shaft, the input shaft bearing a receiving pulley around which pulley a belt transmission is wrapped. The input shaft also bears a component that rotates as one with the shaft and a member for controlling the movement of the pulley along the input shaft in terms of the pulley movement towards or away from the component so that the pulley, which is mounted with freedom to rotate on the input shaft, can be moved from a disengaged position when it is away from the component, into an engaged position when it is close to the component, the pulley having a groove of constant predetermined width for accepting the belt so that when the belt is taut inside the groove, the belt tension is maintained as the pulley moves along the input shaft.
