  • Patent number: 5853177
    Abstract: A sealing device for a drive line slip yoke includes a generally resilient seal and a substantially rigid cover that cooperate to provide a fluid-tight seal at the interface between a slip yoke and an axially moving splined shaft. The seal has a mounting portion that includes a shoulder received within a groove defined on an outer surface of the slip yoke. The cover is snapped over the seal and maintained in position by cooperating tabs on the cover and a groove defined on an outer surface of the seal. The seal includes a sealing portion having three axially spaced and radially inwardly extending lips. A middle lip acts as an O-ring that serves as a back-up in the event that one of the other two lips becomes damaged or deteriorates with use. The substantially rigid cover serves to maintain the seal in proper engagement with the end of the slip yoke and protects the seal from damage potentially caused by debris encountered during operation.

  • Patent number: 5848938
    Abstract: A twin mass flywheel comprising two co-axially arranged flywheel masses which are mounted for limited angular rotation in a drive and over-run direction relative to each other, and a plurality of pivotal linkages. Each pivotal linkage comprises a first link pivotally connected to one of the flywheel masses, a second link pivotally connected to the other of the flywheel masses and a pivot pivotally connecting the first and second links. The action of the links controls relative rotation of the flywheel masses, and the controlling action of the links is supplemented by one or more assister springs which operate over a significant proportion of the full drive direction range of relative rotation. The twin mass flywheel may further include end stops to positively limit relative rotation of the flywheel masses in the drive and over-run directions and may additionally include end stop resilient means which cushion the relative rotation of the flywheel masses just prior to contact of the end stops.

  • Patent number: 5839175
    Abstract: A buckling device used in conjunction with a strap for holding an object firmly in position is provided. The buckling device includes a male fastener and a female fastener. The male fastener includes a strap-mounting body for fixing a first end of the strap thereto and a tongue-like member formed on the strap-mounting body. The female fastener includes a rectangular body having a hollowed inside and formed with an insertion hole; a locking/releasing piece pivotally mounted on the rectangular body; and an elastic piece provided at the insertion hole. To engage, the tongue-like member on the male fastener is inserted into the insertion hole in the female fastener. The tongue-like member pressed on the elastic piece such that the elastic piece is bent downwards and thereby urges forcibly against the tongue-like member, thereby locking the tongue-like member in position in the female fastener and thus securely engages the male fastener with the female fastener.

  • Patent number: 5836060
    Abstract: A truck strap fastener is adapted to enable a strap to be attached to either a downwardly directed hook or to a flat iron carried by standoffs attached to a trailer's frame. Flatbed trailers typically provide either a flat iron bar or a downwardly directed hook as the point of attachment for load securing tie-down straps. A fastener is disclosed that is adapted to attach to either point of attachment, and also to the tie-down strap. The fastener provides a body carrying left and right prongs which jointly fasten in place about a flat iron. Alternatively, a hook opening in the body allows a hook to pass between the left and right prongs and through the hook opening in the body.

  • Patent number: 5836825
    Abstract: A propeller shaft including an FRP tube and joints connected to at least one end of said FRP tube. The FRP tube includes cylindrical end portions into which cylindrical portions of the joints are press-fitted, and intermediate tubular portions which have tapered inner peripheral surfaces connected at their large-diameter ends to terminal ends of inner peripheral surfaces of the cylindrical end portions and which are formed by a helical winding. The intermediate tubular portion is formed as a portion which is to be broken upon collision of the vehicle, and the cylindrical portion of the joint is formed as a breaking member which is adapted to collide against the tapered inner peripheral surface of the intermediate tubular portion by sliding under a shock load. In this way, a propeller shaft can be provided which is capable of absorbing a shock load upon collision of the vehicle.

  • Patent number: 5833277
    Abstract: A pipe connection is formed between a relatively soft pipe segment and a stiffer socket by inserting a split securing ring in a groove of the socket, then spreading this ring and inserting the pipe segment through the split ring into the pipe segment without contact with the split ring. The mounting body maintaining the spread state of the split ring is then removed to allow the spring ring to engage with its intrinsic elastic force along the periphery of the pipe segment. Even if the inner surface of the split ring is provided with a corundum layer or like friction-enhancing structure there will be no damage to the outer periphery of the pipe which might interfere with sealing.

  • Patent number: 5829754
    Abstract: A hub assembly with improved sealing and anti-clogging properties comprising a housing body with a central, longitudinal aligned bore. In the embodiment described herein, a rotating shaft unit on a consistency transmitter is disposed inside the central bore. A flow cavity is formed on the distal end of the housing body which directly communicates with the central passageway of a pipeline containing flowing fluid material. The flow cavity is sufficient in size so that fluid material inside the pipeline may freely flow therein during use. Located around the distal opening of the housing body is an inner bushing made of graphite material. Located immediately adjacent to the inner bushing is a compressible bellows seal which imparts a force against the adjacent, outer surface of the inner bushing. The bellows seal which rotates with the rotating drive unit, has a smooth silicone-carbide end surface which is pressed tightly against the end surface on the stationary inner bushing thereby forming a tight seal.
