Abstract:
A run flat device configured to be fitted to a tubeless mounted assembly for a motor vehicle, which includes a wheel rim and a tire cover including beads mounted against edges of the rim, the run flat device including: an annular supporting structure which is configured to be mounted around the rim so as to support the cover following a drop in inflating pressure inside the mounted assembly, including: three composite spring segments forming sectors in an arc of a circle assembled circumferentially around the rim forming the annular supporting structure by means of transverse pins whose shape geometry is asymmetrical; and an arrangement for locking the beads against the edges which are configured to connect the annular supporting structure to these beads.
Abstract:
The present invention relates to a membrane for secondary air suspension of a land or rail vehicle, in particular of heavy truck or passenger wagon type, this secondary suspension incorporating it, such a vehicle which is provided therewith, and the method for manufacturing this membrane.This substantially toroidal membrane (103) comprises two attachment areas (110) and at least one corded layer (106) of fabric and/or metallic threads which is situated between two radially internal (104) and external (105) elastomer layers and which extends between these attachment areas.According to the invention, said at least one corded layer has its or each of its thread(s) individually sheathed by an elastomer sheath compatible with the internal and external layers.
Abstract:
A system. The system includes a wheel, and a valve assembly secured to an exterior surface of the wheel. The wheel defines a first air passageway. The valve assembly includes a valve member, and an adapter member connected to the valve member. The adapter member adjoins a vehicle wheel hub if the wheel is connected to the vehicle wheel hub. The valve assembly defines a second air passageway and a third air passageway. A first end of the first air passageway adjoins a first end of the second air passageway. A first end of the third air passageway adjoins an air passageway of the vehicle wheel hub if the wheel is connected to the vehicle wheel hub.
Abstract:
In this invention ballistic resistant materials are integrated into a wheel for protection of the Tire Bead Bundle, protection of hardware, and protection of hub components. The Tire Bead Bundle can be protected by supplementing the existing rim flange with ballistic resistant material and/or by placing such material between the flange and the bead bundle. Further, for protection of hardware (including Manual Inflation or CTI Valves), ballistic resistant material can be incorporated over or on wheel hardware. Finally, ballistic resistant materials can be incorporated over or on the wheel hub diameter to reduce the risk of damage due to ballistic attacks.
Abstract:
This is an apparatus and system for integration of Central Tire Inflation (CTI) valve functionality directly into a wheel. The CTI valve may be attached to the wheel or integrated into the wheel. In addition, the CTI valve may have a valve body or the valve components can be installed directly into the wheel. An air passageway between the vehicle air source and the CTI valve and/or an air passageway from the CTI valve to the tire cavity can also be employed.
Abstract:
A tire insert attachment apparatus includes a pin attached to a first part of the insert and extending into a second part of the insert to engage an actuator that draws the bolt into the second part. The actuator includes a tool engagement head that transmits rotational motion of a tool to a translator via a converter, the converter transforming the rotational motion of the head into linear motion imparted on the translator. The translator can be a rack and pinion setup or can be a thread arrangement. Preferably, the head rotates a worm, which rotates a pinion that has threads formed on an inner surface and engaging mating threads on the pin, the pin taking the form of a bolt, such as an eyebolt.
Abstract:
A device for attenuating the periodic vibrations of a mechanical structure adapted to obtain cancellation of periodic vibrations of rotating machines including at least one transducer, detecting original vibrations, delivering a detected signal, a detector of the periodicity of these vibrations delivering a synchronizing signal, and a control circuit and a transducer generating compensation vibrations which are applied to the mechanical structure. The control circuit includes a circuit for synchronous filtering of the detected signal, controlled by the synchronizing signal and delivering a filtered signal whose frequency spectrum contains only the instaneous fundamental frequency of the detected signal. A circuit for regulating the filtered signal delivers an antivibration-control signal applied to a generating transducer in order to minimize the amplitude of the detected signal.
Abstract:
Such a mount comprises a set of thin parallel and spaced plates, of flexible material, extending generally transversely to the vertical direction, the ends of these plates being supported on the one hand on a first armature, fastened to the structure of the vehicle, on the other hand, on a second armature fastened to the engine, through superposed blocks of elastic material, intercalated sandwich-style in said ends of the plates, these blocks embedding the ends of the plates without rigid fastening with the respective armatures. In this way, a great vertical flexibility and a high stiffness in the horizontal directions is obtained.
